CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a divisional of U.S. application Ser. No. 10/876,702, filed on Jun. 28, 2005, which is a divisional of U.S. application Ser. No. 09/575,104, filed on May 19, 2000, now U.S. Pat. No. 7,100,105, the entire contents of each of which are hereby incorporated herein by reference. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to an information processing method and apparatus, and a medium. More particularly, it relates to an information processing method and apparatus, and a medium in which pre-set processing can be executed on a label bonded as a tag sheet on a desk top screen of a personal computer. 
     2. Description of Related Art 
     It has hitherto been a frequent practice to attach a tag sheet as an eye-mark for paper documents, to write a memo on the tag sheet and paste it somewhere for use as reminder. An application program for regenerating a similar thing on a desktop screen of a personal computer has been proposed by the present Assignee. In actuality, a personal computer on which is pre-installed this application program is on sale. In the following description, a tag sheet displayed on the desktop screen is called a label and an application program for displaying a label on the desktop is called a label software. In this label. Not only the test, such as letters, but also speech or pictures, can be handled by exploiting the fact that the label software is an application program on a personal computer. Meanwhile, a paper tag sheet cannot handle the speech or pictures, such as moving pictures. 
       FIG. 1  shows an exemplary representation of a label on the desktop screen. In this figure, not only the text, such as letters, but also letters or pictures, can be pasted on the label L. Meanwhile, the label L in a lower portion of  FIG. 1  shows the state in which a picture has been pasteed in position. If the speech etc is pasted on the label L, and a playback button PB, for example, is clicked, such as with a mouse, the speech can be reproduced. On the other hand, if a stop button B is clicked, such as with a mouse, the speech reproduction can be halted. 
     With the application program (label software) for pasting the label on the desktop, the operation of preparing, moving and deleting the label is possible. Moreover, changes in the text or pictures or speech recording can be performed on the label. 
     However, in the label software, in which, if the label has been corrected, only the latest information following the correction is preserved, so that it is not possible to identify what was the state of the label e.g., at an optional past time point. Moreover, if the label has been deleted, the data converning the label is completely erased, so that the label cannot be seen again, for example, the label cannot be re-displayed on the desktop. 
     SUMMARY OF THE INVENTION 
     It is therefore an object of the present invention to provide an information processing method and apparatus, and a medium, whereby the state of a label at an optional past time point can be identified and whereby, if the label is deleted, the label can be regenerated. 
     If the date and time indicated on a date/time indicator in a pre-set window on the desktop are to be changed, the routine practice is to indicate one of the year, month, day, hour and the minute etc of the date/time indicator and to change its figure. For example, if, with the display “1999: 05: 21: 12: 00: 00” (May 21, 1999, 12 o&#39;clock, 0 min 0 sec), the month figure is to be changed, the cursor is set to the month indication (“05”) to activate it and an entry is made directly from the keyboard. Alternatively, the up/down key on the keyboard is acted upon to change the figure, or a pre-set button for time up/down indication is clicked with a mouse. This time/date indication is highly cumbersome. 
     It is therefore another object of the present invention to provide an information processing method and apparatus and a medium in which, when the personal computer is to deal with the concept of time, time designation can be simplified and facilitated, and in which the information corresponding to the designated time can be retrieved easily. 
     In one aspect, the present invention provides an information processing apparatus including storage means for memorizing a pre-set processing unit, in which to paste the object information of different attributes, in association with the time information, and regenerating means for regenerating the state of the pre-set processing unit associated with a desired date and time, based on the time information. 
     In another aspect, the present invention provides an information processing apparatus including memorizing a pre-set processing unit, in which to paste the object information of different attributes, in association with the time information, and regenerating the state of the pre-set processing unit associated with a desired date and time, based on the time information. 
     In yet another aspect, the present invention provides a medium which permits an information processing apparatus to execute a program including a step of memorizing a pre-set processing unit, in which to paste the object information of different attributes, in association with the time information, and a step of regenerating the state of the pre-set processing unit associated with a desired date and time, based on the time information. 
     With the information processing method and apparatus and the medium, according to the present invention, the pre-set processing unit in which to paste the object information of different attributes and the time information are stored in association with each other, and the state of the pre-set processing unit associated with the desired date and time is regenerated based on the time information, whereby the label state at an optional time point, such as a past time point, can be recognized. Moreover, if the label is deleted, it can be regenerated.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to the drawings, preferred embodiments of the present invention will be explained in detail. 
       FIGS. 2 to 5  illustrate the appearance of a notebook personal computer  1  as an example of application of the apparatus and the method for processing the information according to the present invention. This notebook personal computer  1  is basically constituted by a main body portion  2  and a display portion  3  that can be opened/closed with respect to this main body portion  2 .  FIG. 2  shows the appearance of the notebook personal computer  1  with the display portion  3  being opened relative to the main body portion  2 .  FIG. 3  shows the plan view of the main body portion  2  and  FIG. 4  shows an enlarged view the vicinity of a jog dial  4 , as later explained, constituting the essential portions of the present invention.  FIG. 5  is a side view of the side of the jog dial  4  of the main body portion  2 . 
     On the upper surface of the main body portion  2 , there are provided a keyboard  5 , acted upon when various letters or symbols are to be inputted, a touch pad  6  as a pointing device acted upon for causing mouse cursor movement, and a power source switch  8 . 
     On the front side of the display portion  3 , there is provided an LCD (liquid crystal display)  7  for demonstrating a picture. On the right upper side of the display portion  3 , there are provided a power source lamp PL, a battery lamp BL, a message lamp ML and other LED lamps. 
     Referring to the setting positions of the jog dial  4  in detail, the jog  4  is built in a space between keys A and B (rightmost key) on the keyboard  5  on the main body portion  2 , on substantially the same level as the keys A and B. 
     The jog dial  4  executes pre-set processing responsive to the rotating actuation as indicated by arrow a in  FIG. 4 , while executing pre-set processing responsive to the movement actuation as indicated by arrow b in  FIG. 4 . The pre-set processing executed by the jog dial  4  will be explained subsequently. 
     The structure of this jog dial  4  is first explained. 
     The jog dial  4  includes a rotary encoding unit  12  and a push switch unit  13  on a contact mounting substrate  11 . The rotary encoding unit  12  is adapted for being moved in the horizontal direction within a pre-set range, whilst the push switch unit  13  is fixed. 
     Referring to  FIG. 7 , the contact mounting substrate  11  includes a contact plate  19  comprising a molded resin member in the form of a flat plate having recesses  15 , 17  and a terminal  18 . The recess  15  has a guide rail  14  for movement of the rotary encoding unit  12 , while the recess  17  has a retention wall section  16  for immobilizing the push switch unit  13 . The terminal  18  serves for transmitting electrical signals of the rotary encoding unit  12  to outside. 
     Referring to  FIGS. 8 and 9 , the rotary encoding unit  12  includes a box-shaped casing  20  of molded resin fitted in the recess  15  of the contact mounting substrate  11  and retained for movement within a pre-set range in the horizontal direction as indicated by arrow H 1  in  FIGS. 6 and 9 , and elastic contact legs  21 ,  22  protruded upwards and downwards from an elastic contact member  45  mounted by insert molding on the bottom surface of the box-shaped casing  20 . The rotary encoding unit  12  also includes a rotary member  25  of synthetic resin retained for rotational movement by a columnar shaft  23  formed integrally with the mid portion of the box-shaped casing  20  and which includes a disc-shaped radial contact plate  24  on the lower surface of which is elastically contacted the elastic contact leg  21 , and a peripheral actuating type circular knob  27  mounted by a screw  26  over the rotary member  25  for rotationally actuating the rotary member  25 . With the rotary encoding unit  12 , the lateral surface of the box-shaped casing  20  is pushed in the horizontal direction by a torsion coil spring  29  positioned by a pin-shaped projection  28  on the contact mounting substrate  11  (see  FIGS. 7 and 11 ) so that the rotary encoding unit  12  is biased to a position spaced in a normal state apart from the push switch unit  13 . Moreover, the elastic contact leg  22 , protruded downwards from the bottom surface of the box-shaped casing  20 , is in elastic contact with the contact plate  19  of the contact mounting substrate  11 . 
     The push switch unit  13  is secured by fitting in the recess  17  in the contact mounting substrate  11  so that an actuating button  30  faces the rotary encoding unit  12 , with the rear end of the button compressing against the retention wall section  16 .  19 , as shown in  FIGS. 6 and 7 . 
     A driving projection  31  formed integrally with the box-shaped casing  20  of the rotary encoding unit  12  compresses against the distal end of the actuating button  30  of the push switch unit  13 , as shown in  FIG. 9 . The foregoing is the structure of the jog dial. When the jog dial is to be mounted on an electronic equipment, legs  11 A,  11 B on the lower surface of the contact mounting substrate  11 , the connection terminal  18  of the rotary encoding unit  12  and a connection terminal  32  of the push switch unit  13  are introduced and soldered in mounting openings  33 A,  34 B,  35  and  36  of a printed circuit board  33  of the electronic equipment, with the jog dial being mounted in position with the end of the peripheral actuating knob  27  of the rotary encoding unit  12  opposite to the push switch unit  13  protruding from a gap of an exterior casing  37  of the electronic equipment. 
     The operation of the jog dial is explained. Referring first to  FIGS. 10 and 11 , a protruding portion  27 A from the exterior casing  37  of the peripheral actuating knob  27  mounted on the upper end of the rotary encoding unit  12  is acted upon by a tangential force so as to perform a rotational movement, whereby the rotary member  25  is rotated about the center columnar shaft  23  of the box-shaped casing  20  as the center of rotation. The upper elastic contact leg  21  then slides in elastic contact with the radial contact plate  24  provided on its lower surface. This sliding contact portion generates pulse signals timed to the rotational actuation of the peripheral actuating knob  27 . 
     The generated pulse signals are transmitted from the upper elastic contact leg  21  to the lower elastic contact leg  22  and thence to the contact plate  19  on the contact mounting substrate  11  to which is elastically contacted the elastic contact leg  22 . The pulse signals are then transmitted to the circuit of the printed circuit board  33  of the electronic equipment through the terminal  18  for external connection. 
     The protruding portion  27 A of the peripheral actuating knob  27  then is acted upon with a thrusting force in the horizontal direction interconnecting the center of the knob and the push switch unit  13 , as indicated by arrow H 2 , against the biasing force of the torsion coil spring  29  provided on the contact mounting substrate  11 , as shown in  FIG. 12 , to cause movement of the entire rotary encoding unit  12  in the horizontal direction along the guide rail unit  14  of the contact mounting substrate  11  to push the actuating button  30  with the projection  31  provided on the box-shaped casing  20 . The resulting signal is transmitted to the circuitry of the printed circuit board  33  of the electronic equipment through a connection terminal  21  shown in  FIG. 10 . 
     If the thrusting force applied to the peripheral actuating knob  27  is removed, the rotary encoding unit  12  is pushed back under the elastic recoiling force of the torsion coil spring  29  of the contact mounting substrate  11  to resume the state shown in  FIG. 11 . 
     In the above-described structure, the elastic contact leg  22 , protruded downwards from the bottom surface of the box-shaped casing  20  of the rotary encoding unit  12 , elastically contacts the contact plate  19  of the contact mounting substrate  11 , as means for transmitting the electrical signals of the rotary encoding unit  12  to the contact plate  18  of the contact mounting substrate  11 . Alternatively, the elastic contact leg may be protruded from the contact mounting substrate  11  so as to be elastically contacted with the contact plate on the bottom surface of the box-shaped casing  20 . The foregoing is the explanation of the structure and the operation of the jog dial  4  provided on the right lateral surface of the main body portion  2 . 
     Of course, the jog dial  4  may be provided on the left lateral surface of the main body portion  2 . The jog dial  4  may also be arranged centrally of the front surface of the main body portion  2  so that the jog dial  4  can be actuated with a thumb finger as the touch pad  6  is actuated with the index finger. The jog dial may also be arranged on the left or right surface of the display portion  3  carrying the LCD  7 , or along the left or right edge of the touch pad  6 . The jog dial may also be arranged longitudinally between left and right buttons or longitudinally between G and H keys of the keyboard unit  5 . The jog dial may also be arranged in an angled direction to permit facilitated actuation with respective fingers without distinction as to longitudinal or transverse directions. The jog dial  4  may also be arranged at a position permitting actuation with a thumb finger on a lateral surface of the mouse as the pointing device. An exemplary electrical structure of the notebook personal computer  1  is explained with reference to  FIG. 2 . a central processing unit (CPU)  11  comprises e.g., Pentium (trademark) of INTEL INC., and is connected to a host bus  52 . To the host bus  52  is connected a north bridge  53  which in turn is connected to a PCI bus  56 . The north bridge  53  comprises e.g., 400BX manufactured by INTEL. INC., and is adapted for controlling the CPU  51  or the main memory  54  with its periphery. The north bridge  53  and the south bridge  58 , as later explained, constitute a so-called chip set. 
     The north bridge  53  also is connected to a main memory  54  and to a cache memory  55  adapted for caching data used by the CPU  51 . Although not shown, a first-order cache memory is enclosed in the CPU  51 . 
     The main memory  54  comprises e.g., a DRAM (dynamic read-only memory) adapted for storing the programs executed by the CPU  51  or data necessary for the operation by the CPU  51 . Specifically, at the tune point of end of startup, an E-mail program  54 A, an auto-pilot program  54 B, a jog dial state monitor program  54 C, a jog dial driver  54 D, an operating program (OS)  54 E and other application programs  54 F 1  to  54 Fn are transferred from an HDD  70  for storage in the main memory  54 . 
     The E-mail program  54 A is a program for exchanging communication text over the network with communication networks, such as telephone network  76 , over a modem  75 , which will be explained subsequently. The E-mail program  54 A also has the function of acquiring oncoming mails as a specified function. This oncoming mail acquiring function inquires whether or not a mail addressed to the user has arrived at the mail box  79  to a mail server  78  of a provider  77  and acquired a mail addressed to the user, if any. 
     The auto-pilot program  54 B sequentially starts pre-set plural processing operations or programs to perform the processing. 
     The OS (basic program software)  54 E, typified by the Windows 95 or Windows 98 (trademarks) by MICROSOFT INC. or MAC OS (trademark) by APPLE COMPUTER INC., controls the basic operations of the computers. 
     The jog dial state monitor program  54 C receives the notice from the respective application as to whether or not the applications are adapted for coping with the jog dial. If the notice is affirmative, the jog dial state monitor program  54 C operates to demonstrate what can be done by actuating the jog dial  4 . The jog dial state monitor program  54 C is usually in a state of awaiting an event of the jog dial  4  and owns a list for receiving notices from the application. The jog dial state monitor program  54 C is responsive to the actuation of the jog dial state monitor program  54 C to execute various functions. 
     A video controller  57  is connected to a PCI bus  56  and is adapted for controlling the display on the LCD  7  on the display portion  3 . 
     To the PCI bus  56  is connected a sound controller  64  adapted for capturing an input from a microphone  66  or supplying audio signals to a speaker  65 . To the PCI bus  56  is also connected a modem  75  which can be connected over a public telephone network  76  or an Internet service provider  77  to a communication network  80 , such as Internet, or to a mail server  78 . 
     To the PCI bus  56  is also connected the south bridge  58  comprising e.g., PIIX4E of INTEL INC. and which is adapted for controlling various I/O (input/output). That is, the south bridge  58  comprises an IDE (Integrated Drive Electronics) controller/configuration register  59 , timer circuit  60  and an IDE interface  61 , and is adapted for controlling a device connected to the IDE bus  62  or a device connected via an ISA/EIO (Industry Standard Architecture/Extended Input Output) bus  63  or an embedded controller  68 . 
     The IDE controller/configuration register  59  is made up of two IDE controllers, namely a so-called primary IDE controller and a secondary IDE controller, and a configuration register. These IDE controllers are not shown for simplicity of the drawings. 
     The primary IDE controller is connected over the IDE bus  62  to a connector, not shown. An HDD  67  is connected to the connector. When bay devices, as so-called IDE devices, such as CD-ROM drive, second HDD or FDD, not shown, are loaded over other IDE buses, the secondary IDE controller is electrically connected to connectors of the loaded bay devices. 
     Meanwhile, the HDD  67  has stored therein plural application programs  67 F 1  to  67 Fn, in addition to the autopilot program  67 B, auto-pilot program  54 B, jog dial state monitor program  54 C, jog dial driver  54 D and the OS (basic program software)  67 E. The above-mentioned respective programs  67 A,  67 B,  67 C,  67 D,  67 E and  67 F 1  to Fn in the HDD  67  are sequentially transferred to the RAM  54  for storage therein during the startup (bootstrap) process. 
     To the ISA/EIO bus  63  is also connected an embedded controller  68  which comprises a micro-controller and which is used as an I/O controller. That is, the embedded controller  68  is constructed by an interconnection of an I/O interface  69 , a ROM  70 , a RAM  71  and a CPU  72 . 
     In the ROM  70 , there are stored from the outset a LED control program  70 A, a touchpad input monitor program  70 B, a key input monitor program  70 C, a wakeup program  70 D and a jog dial state monitor program  70 E. 
     The LED control program  70 A is a program for controlling the lighting of a lamp, such as a power source lamp PL, a battery lamp BL, a message lamp ML, if necessary, or other LEDs. The touchpad input monitor program  70 B is a program for monitoring the user input from the touch pad  6 . The key input monitor program  70 C is a program for monitoring the input from the keyboard  5  or other key switches. The wakeup program  70 D is a program for checking, based on current time data supplied from a timer circuit  60  within the south bridge  58 , whether or not the time is the pre-set time and, should the time be the pre-set time, various chip power sources are managed for starting pre-set processing operations or programs. 
     The jog dial state monitor program  70 E is a program for perpetually monitoring whether the rotary encoding unit  12  of the jog dial  4  has been rotated or pressed. The jog dial state monitor program  70 E will be explained in detail subsequently. 
     In the ROM  70  is further written BIOS (basic input/output system)  70 F. The BIOS is a basic input/output system, that is a software program controlling data exchange (input/output) between the OS or the application software and peripherals, such as display, keyboard or HDD. 
     The RAM  71  includes registers for a touchpad input status, a key input status and for time setting, and a jog dial status monitor I/O register, as registers  71 A to  71 F. For example, an LED control register  71 A controls the lighting of a message lamp ML displaying the instantaneous rising state of the E-mail on thrusting the jog dial  4  as explained later. The key input status register  71 C stores an actuating key flag when the jog dial  4  is pushed for one-touch operation as later explained. The time setting register  71 D is able to set optional time. 
     To the embedded controller  68  are connected the jog dial  4 , touch pad  6  and the keyboard  5  through a connector, not shown, to output signals associated with the operations of the jog dial  4 , touch pad  6  and the keyboard  4  to the ISA/EIO bus  63 . To the embedded controller  68  are also connected the power source lamp PL, battery lamp BL, message lamp ML and other LED lamps. 
     To the embedded controller  68  is also connected a power source control circuit  73  in turn connected to an enclosed battery  74  or an AC power source. The power source control circuit  73  furnishes the necessary power to each block, while managing control to charge secondary batteries of the peripherals. The embedded controller  68  also monitors a power source switch  8  operated on turning the power source on or off. 
     The embedded controller  68  is able to execute the above-mentioned programs  70 A to  70 E by an internal power source at all times even when the power source  8  is turned off. That is, the above-mentioned programs are running at all times even if no windows are opened on the LCD  7  of the display portion  3 . That is, the embedded controller  68  executes the jog dial state monitor program  70 E at all times even when the power source switch  8  is off or the OS 54  is not started on the CPU  51 . In particular, the embedded controller  68  furnishes the function of a programmable power key (PPK) to the notebook personal computer  1  even if the computer is not provided with a dedicated key, such that the desired software or the script file can be started simply when the user pushes the jog dial  4  in the power saving mode or in a power down state. 
     Referring to  FIGS. 14 to 16 , the operation of the e 48  on execution of the jog dial state monitor program  70 E is explained.  FIG. 14  shows the hardware configuration for monitoring of the state of the rotary encoding unit  12  of the jog dial  4  by the embedded controller  68  through a rotation sensor  85 .  FIG. 15  shows a flowchart for illustrating the execution of the jog dial state monitor program  70 E by the embedded controller  68 .  FIG. 16  shows a timing chart for illustrating the operation of the rotation sensor  85  shown in  FIG. 14 . 
     When the rotary encoding unit  12  of the jog dial  4  is rotated towards left or right, the rotation sensor  85  detects whether the rotation of the rotary encoding unit  12  is the leftward rotation or the rightward rotation, based on the timing of the signals A and B shown in  FIG. 16 . If the rotation of the rotary encoding unit  12  is detected to be the rightward rotation, the rotation sensor  85  sends a rightward rotation pulse to a counter ( 1 )  86  of the embedded controller  68 . Conversely, should the rotation of the rotary encoding unit  12  be detected to be the leftward rotation, the rotation sensor  85  sends a leftward rotation pulse to a counter ( 2 )  87  of the embedded controller  68 . 
     The embedded controller  68  executes the jog dial state monitor program  70 E to monitor the variation of the counter ( 1 )  86  and the counter ( 2 )  87 , difference therebetween and whether or not the jog dial  4  has been pushed, by polling at intervals of 5 ms. 
     First, at step S 1  in  FIG. 15 , the count value counter  1 (T−1) at time T−1 is subtracted from the count value Counter  1  (T) at current time T of the rightward rotation pulse to find the variation Counter  1  of the count value of a counter  87 . 
     Then, at step S 2 , the count value Counter  1 (T−1) at time T−1 is subtracted from the count value Counter  1  (T) at current time T of the leftward rotation pulse to find the variation Counter  2  of the count value of a counter  87 . 
     At step S 3 , the difference between the variations of the count values, that is the difference between the variation Counter  1  and the variation Counter  2 , is found. If this difference between the variations is negative, the rotation is leftward. 
     On the other hand, the pressed state of the jog dial  4  is acquired at step S 4 . At step S 5 , the variations as found at step S 3  are checked. At step S 6 , it is checked whether or not the pressed state of the jog dial  4  has been changed. If it is verified that the variation is detected at step S 5 , or that the pressed state has been changed at step S 6 , the current pressed state of the jog dial  4  and the variation are notified by interrupt through an I/O register  71 F to the jog dial driver  54 D, started by the CPU  51 . 
     If there is no change at step S 6  in the pressed state of the jog dial  4 , the program moves to step S 8 , where the polling is terminated and the processing as from step S 1  is repeated after lapse of 5 ms. 
     After the power source switch  8  is turned on, the CPU  51  executes the jog dial state monitor program  54 C in accordance with the procedure shown in  FIG. 17 . 
     That is, at step S 31 , it is perpetually monitored whether or not the jog dial  4  has been acted upon. It is also monitored whether or not the E-mail program  54 A or other applications  54 F 1  to  54 Fn have been activated. Here, the state of the jog dial  4  is monitored to monitor the processing from the jog dial state monitor program  70 E on the side of the CPU  51  through the jog dial driver  54 D, with the operation being substantially the same as the operation explained with reference to  FIG. 14 . 
     If a notice on the operation of the jog dial  4  is sent at step S 32  from the jog dial driver  54 D, the program moves to step S 33  where it is verified whether or not there is any active application. If there is no active application, the program proceeds to the launcher operation and, if otherwise, to an event operation. The launcher operation means the operation of selecting the registered application. 
     The launcher operation is explained briefly. This launcher operation is valid on the condition that there is currently no active application, as described above. In the jog dial menu are displayed applications previously registered in the launcher list. In the launcher list, there are registered application associated with the jog dial. 
     When the launcher operation is executed, the jog dial menu indicating the launcher state is demonstrated on the LCD  7 . In the jog dial menu, there is displayed and started a list of applications associated with the jog dial. 
     Assume that, when the pre-set OS 54 E has been started by the CPU  51 , there is no activated application, and the user has pressed the jog dial  4  once in the direction indicated by arrow b in  FIG. 4 . The pushed state of the jog dial  4  then is received by the jog dial driver  54 D by the forwarding of the flag state through the I/O register by interrupt, as explained with reference to  FIGS. 14 to 16 . So, the jog dial driver  54 D routes an actuation notice to the jog dial state monitor program  54 C similarly executed by the CPU  51 . 
     The CPU  51  then starts the application program pre-registered in the launcher list in association with the jog dial for adjusting the volume of the speaker  65 , luminance of the LCD  7  and its contrast and selecting the application, so that a jog dial menu shown in  FIG. 18  is demonstrated on the LCD  7  of the display portion  3  shown in  FIG. 2 . In this jog dial menu, there re displayed menu items “sound volume”, “luminance”, “contrast” and “selection of the application”, associated with the processing operations of the sound volume adjustment, adjustment of luminance on the display portion, contrast adjustment and the selection of the application. In this example, the selector A is displayed as the initial state on the menu item “sound volume”. 
     When the user then scrolls, that is rotates, the jog dial  4  in the direction indicated by arrow a in  FIG. 4 , for causing the movement of the selector A, the embedded controller  68  executes the calculations, explained with reference to  FIG. 15 , in accordance with the jog dial state monitor program  70 E, and notifies the calculated variation to the jog dial driver  54 D executed on the CPU  51 . 
     The jog dial driver  54 D then routes an actuation notice to the jog dial state monitor program  54 C so that the CPU  51  causes the selector A to be shifted to a menu item desired to be executed by the user. If, when the jog dial menu of  FIG. 17  is displayed on the LCD  7 , that is when the selector A is demonstrated on the “sound volume”, the user rotates, that is scrolls, the jog dial  4  downwards a pre-set distance or angle as indicated by arrow a in  FIG. 4 , the selector A shifts to the menu item “luminance”. If the user rotates the jog dial  4  further downwards, the selector A shifts to the menu item “selection of the application”, as shown in  FIG. 20 . 
     If, as a result of the rotating actuation by the user of the jog dial  4 , the selector A has shifted to the menu item corresponding to the desired processing, the user pushes the jog dial  4  down in the direction indicated by arrow b in  FIG. 4 , by way of performing the selecting operation. So, if the selector A is displayed on the menu item “luminance”, as shown for example in  FIG. 19 , the sub-menu associated with the menu item “luminance” is displayed, as shown in  FIG. 21 . In the present example, six sub-menus “5” to “0”, corresponding to the sub-menu “5” selected when the luminance is to be maximum through to the sub-menu “0” selected when the luminance is to be minimum, are displayed. The amount of the variation of the jog dial  4  corresponding to the rotating processing of the jog dial  4  by the user is found by the processing by the embedded controller  68  shown in  FIG. 15  and is sent to the jog dial driver  54 D, while being monitored by the jog dial state monitor program  54 C, to cause movement of the selector B. 
     On the other hand, if the selector A is displayed on the menu item “selection of the application”, as shown in  FIG. 20 , the sub-menu corresponding to the menu item “selection of the application”, is displayed by the selecting operation by the user, as shown in  FIG. 22 . In the present example, the sub-menu item “word processor”, selected on startup of a word processor application, sub-menu item “E-mail” selected on startup of an E-mail program, sub-menu item “table calculations” selected on startup of a table calculation program, sub-menu item “Internet” selected on startup of an Internet program and the sub-menu item table “calculator” selected on startup of a table calculator program, are demonstrated. In the present example, the selector B on the sub-menu is demonstrated on the topmost submenu item. 
     The user then rotates the jog dial  4  to cause the selector B to be moved to the submenu item desired to be selected, and then presses the jog dial  4  to perform the selecting operation. This selects the submenu item displayed on the selector B to permit the corresponding processing to be executed. If, for example, the submenu item “3” in the example of  FIG. 21  is selected, the luminance corresponding to the submenu item “3” is set. On the other hand, if the sub-menu item “Internet” is selected in the example of  FIG. 21 , the Internet program is started. 
     The case in which, after turning on of the power source switch  8 , the CPU  51  executes the jog dial state monitor program  54 C, and there is an active application at step S 33  in  FIG. 17 , is explained. This case corresponds to the event operation described above. The application needs to be associated with the jog dial and specifically is to be a pre-set application program having a picture displaying function. In the present instance, the map of Japan shown in  FIG. 23  is displayed on the LCD  7  by the application program. If the user rotates the jog dial  4  in this case, the picture is enlarged at a point indicated by a printer as the center, as shown in  FIG. 24 . 
     If the jog dial  4  is rotated in the opposite direction to that when the picture is enlarged, the picture is contracted, that is restored to the original size. So, in the pre-set application program having the picture displaying function associated with the jog dial, the picture displayed on the LCD  7  can be contracted or enlarged in association with the rotating operation of the jog dial  4 . 
     The above-mentioned applications as the specified examples are both the jog dial related software. However, not all applications stored in the HDD  67  and memorized in the RAM  54  after completion of the OS 54 E startup are not associated with the jog dial  4 . For example, the application  54 F 3  is not associated with the jog dial. The processing on the jog dial which the CPU allocates to the jog dial related application and to the jog dial unrelated application. For this reason, the jog dial related application notifies to the jog dial state monitor program  54 C executed on the CPU  51  in accordance with the procedure shown in  FIG. 26 . 
     First, at step S 61 , the jog dial related application declares to the jog dial state monitor program  54 C that it is a jog dial related application. The jog dial state monitor program  54 C then at step S 62  adds the application software to the list of the jog dial related software. 
     Although not shown specifically, in the above explanation, the jog dial menu display may also be made known to the user in the form of a jog dial guide as a display proper to the application. 
     That is, at step S 63 , the jog dial related application notifies the illustration of the jog dial operation in the current state to the jog dial state monitor program  54 C by a letter string. At step S 64 , a jog dial window  90  shown in  FIG. 27  is displayed at step S 64  to demonstrate letter strings, such as “jog dial guide”, “zoom”, “in”, “fit” or “out”. 
     The jog dial related application at step S 65  changes the letter strings depending on the state of the activated window to rewrite the list of the jog dial state monitor program  54 C. So, if the jog dial related application is active, the display of the jog dial window  90  demonstrates, in letter strings, the illustration as to which operation is to be performed by the application subject to jog dial actuation. 
     The application is classed into a jog dial related application and a jog dial non-related application, as discussed above. The distinction between the jog dial related application and the jog dial non-related application is made in accordance with the procedure shown in  FIG. 24 . 
     First, at step S 51 , the UI which performs an event operation is displayed on a window. 
     It is then checked at step S 52  whether or not the application is a jog dial related application corresponding to a pre-registered active application and a decision is given at step S 53 . If, at step S 53 , the application is verified to be a jog-dial non-related application, the program moves to step S 54  to make a message notice proper to the jog dial in accordance with the procedure shown in  FIG. 15 . If the application is a jog-dial non-related application, the program moves to step S 55  to make standard message notice. 
     Specified examples of the jog-dial related application and the jog-dial non-related application are shown below. 
     A first specified example is an application software showing a tag on a desk top for realizing the time-shiftable desktop environment, as disclosed in JP Patent Application No. 11-108535 (Internal Priority Application H-10-321772) proposed by the present Assignee.  FIG. 25  shows exemplary picture in case temporal cooperation is made between an application for realizing a time-shiftable desktop environment and an application of a picture browser. It is assumed that, in  FIG. 25 , retrieval is made on a desk top by an application realizing the time-shiftable desktop environment and time shifting is made until a given letter string presents itself on the desk top. It is assumed that, in the present embodiment, a letter string “wearable” is inputted to a retrieved letter input space  125 , the letter string “wearable” is retrieved by an application realizing the time-shiftable desktop environment and the icon or the letter string used at a time of a conference pertinent to the on a time-shiftable desktop window  200  letter string “wearable” is displayed on the time-shiftable desktop window  200 . It the present case, the desktop environment of the conference held on Nov. 20, 1998 Friday at 3 pm is displayed on the window  200 , as may be seen from the displayed contents of a date and time display  127 . If the “application time” is determined by the application realizing the time-shiftable desktop environment as discussed above, the time information is notified to a picture browser, which, on reception of the time information, displays the photo picture shot at the adapted for time (time during conference). In the present case, a photo picture shot on Nov. 20, 1998 at 4 pm is displayed on the window  201 . If conversely the picture browser is acted upon, the state of the desktop at a time point of the picture photographing is regenerated. Therefore, it can be understood under which situation the photo is shot, even though no caption (explanation) is attached to the picture. If the application is associated with the event operation of the jog dial  4 , the temporal moving direction and quantity of the time-shiftable desktop  200  can be acted on by the jog dial  4 . That is, for example, a jog dial window  90  may be displayed on the lower right corner of the time-shiftable desktop  200  to realize temporal movement to the past or to the future in association with the scrolling of the jog dial  4 . 
     A second specified example is the Smart Capture (trademark) as a tool for capturing still and moving pictures of a digital video camera. 
     A third specified example is the MediaBar as a music actuating tool. In this MediaBar, playback of the next number or the previous number may be selected or playback may be paused by scrolling with e.g., a jog dial or a keyboard. 
     A fourth specified example is the SmartPad (trademark) as a handwriting memo tool employing a touch pad  6 . The touch pad  6  is used as absolute coordinate detection means. The handwritten memo input from the touch pad  6  is processed by the drawing application and displayed. 
     As a fifth specified example, a schedule management tool, for example, may be used. 
     The setting of the jog dial is explained. By actuation of a “set up” button of the jog dial window  90 , the picture may be shifted to a jog dial setting picture  300  shown in  FIG. 26 . For example, an application can be registered in an application list started from a launcher application. The setting is registered by selecting a software registration area  301  and attaching a jog dial mark to the desired application. The setting registration comes to a close on clicking an OK button. 
     A label software of the present embodiment is now explained. 
     The label software of the present embodiment is an application program for realizing, on a desktop screen of a personal computer, the operation of exploiting a tag sheet attached as an index mark tio a paper document, writing a memo on the tag sheet and affixing it somewhere for use as a reminder. In the present embodiment, the label sheet displayed on the desk top screen is called a label sheet and an application program for displaying the label on the desk top is called the label software. 
     The label software of the present embodiment has the functions of handling the text of letters or symbols, still pictures, speech or music sound, as an object that can be affixed to the label as a tag sheet displayed on the desk top, editing a text affixed to the label, the recording and/or reproducing function of the sound affixed to the label, capturing/displaying a picture to be affixed to the label and cooperating with a application software fir capturing the picture from the CCD cam-era attached to the personal computer. The label software of the present embodiment also includes the functions of preparing a label having a change hysteresis as the temporal management function, fully supporting the jog dial with respect to the temporal management function and of handling a link as an object affixed to the label. 
     In the structure of data handled by the label software of the present embodiment, having these functions, there are three items, namely a project, a label and an object.  FIG. 27  shows the relationship between these data. 
     The adapted for project is a set of all label data. Usually, a project formulates only one project. In a project, there are all label information of past, present and future. However, for furnishing sample contents or project information exchange over the Internet, the label software of the present embodiment supports the project switching and addition. The project will be explained in detail subsequently. 
     The label corresponds to a tag sheet on a desktop. The label has the information as from its formulation until its disposal. This information is the information on the entire operations which the user performed through a personal computer on the label as from its formulation until its disposal, such as size or color change of the label, text correction, picture change or sound change. Although the label position information always has the attributes of displaying the latest information, the information between the labels, between the windows or between the label and the window is not held. The label may be classed into three sorts, that is the current label, past label and the future label. The current label is a label prepared at a time ahead the current time and which has not yet been deleted at the current time point. The relationship between the time of preparation of the current label, the current time and the end (deletion) time is (preparing time≦current time&lt;end time (deletion time). The past label is a label already deleted at the current time point. The relationship between the time of preparation of the current label, the end (deletion) time and the current time is (end time (deletion time)&lt;preparing time≦current time). The future label is a label not formulated as yet at the current time point, and the preparing time is set to a future time point. The relationship between the current time, the time of preparation of the current label and the end (deletion) time is (the current time&lt;the time of preparation&lt;the end (deletion) time. The label will be explained subsequently in detail. 
     The object is data affixed in the label and may specifically be enumerated by a text object, a picture object, a sound object and a link object. First, the overall structure of a picture is explained. 
     The main constituent parts of a desk top screen when the label software of the present embodiment is executed are explained. First, the overall structure of a screen is explained. 
     The label software state of the present embodiment (state of the application) may be classed into a normal mode and a time view mode. 
     The normal mode is a state in which a label has been affixed to the desk top in a state other than the time view mode.  FIG. 28  shows an example of a desk top picture in the normal mode. In this figure, the label is denoted by a reference figure L. in this normal mode, an icon IL of the label software of the present embodiment is displayed on a task tray TT of the task bar TB on the desktop screen. By accessing (clicking) this icon IL using a pointing device, such as mouse, it is possible to control the entire functions of the label software application of the present embodiment. 
     The time view mode is a mode in which temporal operation by the label software of the present embodiment is possible and which can be classed into three states of the present, past and future modes.  FIGS. 29 to 31  show an illustrative structure of a desktop screen in the present mode, an illustrative structure of a desktop screen in the past mode and an illustrative structure of a desktop screen in the future mode, respectively. As may be seen from these figures, the current state, past state and the future state of the label contained in the project are displayed for the present, past and future modes, respectively. On the desktop screen of  FIGS. 29 to 31 , letters “present”, “past”, and “future” indicating the respective modes are displayed at the center and at the four corners of the desktop screen of  FIGS. 29 to 31 . By these indications, the user is able to visually recognize the mode which prevails, that is the present mode, past mode or the future mode. Also, in the time view mode, the icon IL of the label software of the present embodiment is displayed on the task tray TT of the task bar TB of the desktop screen. 
     On switching to the time view mode, the entire area on the desktop is covered by a label software picture and a label is displayed thereon. If there are plural monitors, the entire areas of the entire monitors are covered by a label software picture and a label is displayed thereon. At this time, a time view console TVC for enabling the display/change of the time now acted on is displayed on the screen. Meanwhile, the time view console TVC is displayed in the standard state on the upper part of the screen.  FIGS. 29 to 31  show an example of displaying the time view console TVC in the lower portion of the screen. The time of the state in which the desktop display is made in the time view mode is referred to below as the operation time. 
     The window screen of the label displayed on the desktop is made up of a play/pause button, a stop button, a link button, a menu button, an object that can be affixed to the label (text, picture and sound), icons (alarm, repetition) and the like.  FIG. 32  shows an example of the window picture of the label L. In the case of the label L, shown in  FIG. 32 , the play/pause button PB, stop button SB, link button LB and the menu button MB are displayed and the text, sound, picture and the link are affixed in the label L. Meanwhile, the state in which the picture is displayed is shown. 
     The play/pause button PB is used for commanding the playback start and the pause of the sound when the label L contains a sound object. That is, if the label L contains the sound object, and the play/pause button PB is pressed, such as by mouse click, the sound is reproduced, whereas, if the play/pause button PB is pressed (clicked) during the sound reproduction, the sound reproduction is paused. On the other hand, the play/pause button PB is PB is associated with a tool chip TCt indicating the play time (sound recording time) shown in  FIG. 33 , such that, when a cursor MC is moved on the button PB, the tool tip TCt indicating the play is displayed. 
     The stop button SB is used for stopping the sound reproduction. If the stop button SB is pressed (clicked) during the sound reproduction, the sound reproduction is stopped. 
     The link button LB is used for opening the file of the link destination associated with the label L and for displaying the window of the HTML (Hypertext Markup Language). If a file path is set as an address of the linking destination on the label L, and the link button LB in the label window of  FIG. 32  is pressed (clicked), the file set by the file path is opened. If the URL (uniform resource locator) is specified as a linking address in the label L, and the link button LB is pressed (clicked), the window of the HTML (Hypertext Markup Language) is displayed. Also, the link button LB is associated with the tool chip TCl indicating the link contents (file path or URL of the linking destination), such that, when the cursor MC has been migrated onto the link button LB, the too chip TCl indicating the link contents is displayed. 
     The menu button MB, arranged on the right upper end of the label window, is used for displaying the menu of all operations relevant to the label, such as file, addition of new labels, time, label, help etc. If the menu button MB is pressed (clicked), the menu items, such as file, addition of desktop screen, time, label, help etc are displayed as the pull-down menu in the vicinity of the menu button MB. Meanwhile, when the right button of the mouse is clicked in each part of the lebel, or the application key is pushed with focussing, menu items (context menu items) are displayed as when the menu button MB is clicked. The pull-down menu activated on clicking the menu button MB on the label window and the context menu by the application key will be explained subsequently in detail. 
     Depending on the status or the setting of the label, an icon representing the current state is displayed on the upper right part of the label L (left: neighboring side of the menu button MB, as an example). The icon may be classified into an alarm icon IA and a repetitive icon IR as shown in  FIG. 35 . The alarm icon IA is displayed when an alarm is set on the label, whereas the repetitive icon IR is displayed when a repetitive display is set. 
     The label in the state of the time view mode may sometimes be a correction-inhibited label. The correction-inhibited label is varied in color in its edge from the color of the edge of the correctable label for distinction from the correctable label. That is, in the present embodiment, distinction is made by the label color so that the user will comprehend due to which state of the label it is uncorrectable. For example, the uncorrectable label is differentiated from the correctable label by having a purple or blue color. For example, if the label edge color is “purple”, it indicates that the present label is of the past mode or the future mode and cannot be corrected (correction-inhibited label). If the label color is “blue”, it indicates that the label is the past label, which is not corrected for any modes. 
     The time view console TVC has two window states, that is a state of a bar-shaped window shown in  FIGS. 29 to 31  and in  FIG. 36  and a state of a floating window as shown in  FIG. 37 . That is, the time view console TVC can be dragged by a pointing device, such as a mouse. When the time view console TVC is moved upwards or downwards in the screen, it is in a bar-shaped window, as shown in  FIGS. 29 to 31  and in  FIG. 36 , and otherwise in a floating-state window, as shown in  FIG. 37 . Although the screen configuration differs in the bar state and in the floating state, the function of the time view console is the same. 
     The bar-state window of the time view console TVC shown in  FIG. 36  is made up of a window title portion wt, the Christian era gauge unit cg, current button bb, an operation time display unit oti, an up-down button tub and tdb, time increasing/decreasing step selection list box ssl, a time increasing/decreasing step selection menu button sb, a menu button mb, a closure button cb, a help button hb and a rotation animation unit ra. 
     The window title unit wt displays a title of the window, a time view in the present example, and displays only the title. That is, the window title unit wt is provided for clarifying that the application responsible for the current picture in its entirety is the label software. 
     The Christian era gauge unit cg is provided for clarifying for the user at a glance to which time in the Christian era corresponds the label currently displayed. This Christian era gauge unit cg is displayed so that the time as the label is displayed on the screen will be perpetually at the center of the gauge. A yellow vertical line, for example, is also displayed for clearly displaying the time. That is, the time at the center portion of the Christian era gauge unit cg corresponds to the label of the past or future label, or to the current time, instead of corresponding to the real time (current time of the real world). The Christian era gauge unit cg in the example of  FIG. 36  is an illustrative display for a case wherein the time of the state in which a label is displayed on the screen, that is the time at the gauge center, is November 1999. A yellow vertical line  1   e  is displayed at the gauge center. In the Christian era gauge unit cg, a red vertical line  1   r  indicating that the real time (current time of the real world) is e.g., May 1999. That is, according to Christian era gauge unit cg, the relative position between the time corresponding to the displayed label, such as November 1999, and the real time, such as May 1999, can be recognized readily. 
     The current button bb is used for commanding restoration from the time corresponding to the displayed label to the real time (current time of the real world). Meanwhile, if the time is reset to the current time (current time of the real world) by the current button bb, the state of the label software (state of the application) is kept in the time view mode. 
     The operation time display unit oti displays which time state is the state in which a label is displayed on the screen. In the example of  FIG. 36 , it is the state of the label on Nov. 11, 1999, 3.27.9 pm, that is displayed on the screen. 
     The up-down buttons tub and tdb are used for advancing or delaying the time demonstrated on the operation time display unit oti by specified time advancing delaying unit (time advancing delaying step). Assume that there is focus on the operation tune display unit oti and that one of the year, month, day, hour, minute and second on the operation time display unit oti is activated. If now the up-button tub is pushed, the value of the activated portion is increased by a specified time increasing/decreasing unit (time increasing/decreasing step). In the label software of the present embodiment, the function which is the same as that of the up/down buttons tub and tdb may also be implemented by rotation of a wheel of a mouse fitted with the wheel, up/down operation of a cursor key or rotation of the jog dial  4 . That is, in the present case, if there is a focus on the operation time display unit oti, one of the year, month, day, hour, minute and second on the operation time display unit oti is activated, and the wheel of the mouse fitted with the wheel is rotated, the up/down cursor key on a keyboard is pushed, or the jog dial  4  is rotated. The value of the activated portion is increased or decreased in specified time increasing/decreasing units (time increasing/decreasing steps) to advance or lag the time. 
     The time increasing/decreasing step selection list box ssl demonstrates the time increasing/decreasing unit (time increasing/decreasing step) in case the time of the operation time display unit oti is increased and decreased. Stated differently, there is displayed in the time increasing/decreasing step selection list box ssl the time increasing/decreasing unit (time increasing/decreasing step) of an activated one of the year, month, day, hour, minute and second, as the activated time display portion, demonstrated on the time increasing/decreasing step selection list box ssl in the example of  FIG. 36 . In the present embodiment, the time increasing/decreasing units (time increasing/decreasing steps) are 100 years, 10 years, 1 year, 1 month, 1 hour, 1 minute, 1 second and varying time point. One of these time increasing/decreasing steps is displayed in the time increasing/decreasing step selection list box ssl. Meanwhile, the time increase/decrease in varying time units means increasing/decreasing the time with the time as from a time point when certain operation is made on the label by the user to modify the label, such as label movement, size change or object correction, that is a time point the label state on the desktop is changed, until the time point of occurrence of the next change, as one unit. So, if the time is increased or decreased in terms of the varying time units, the time interval of change with the increase/decrease at the change point is not constant. 
     The time increasing/decreasing step selection menu button sb is used for specifying the time increasing/decreasing steps demonstrated on the time increasing/decreasing step selection list box ssl by a menu selection button. Stated differently, the time increasing/decreasing step selection menu button sb is used for selecting the time displaying portion, that is the year, month, day, hour, minute or second displayed on the operation time display unit oti, that is desired to be activated. If this time increasing/decreasing step selection menu button sb is pushed, that is clicked, the time increasing/decreasing units (time increasing/decreasing steps), such as 100 years, 10 years, 1 year, 1 month, 1 hour, 1 minute, 1 second and on varying time unit, is displayed as a pull-down menu below the time increasing/decreasing step selection menu button sb. Therefore, by selecting the desired time increasing/decreasing step, the corresponding time displaying portion from the indications of the year, month, day, hour, minute and second is selected and activated. That is, if, for example, the 1 month is selected from the pull-down menu of the time increasing/decreasing step selection menu button sb, the month displaying portion of the display portions of the year, month, day, hour, minute and second is activated. In this state, rotation of the up/down buttons tub and tdb or the wheel of the mouse fitted with such wheel, thrusting the up/down cursor key downwards or rotation of the jog dial  4  enables the month can be changed. 
     Moreover, in the label software of the present embodiment, the same function as the function of selecting the time increasing/decreasing steps by the time increasing/decreasing step selection menu button sb may be realized by rotation of the up/down buttons tub and tdb or the wheel of the mouse fitted with such wheel, thrusting the up/down cursor key downwards or rotation of the jog dial  4 . That is, in the present case, if, with the focus on the operation time display unit oti, the wheel of the mouse fitted with such wheel is rotated, the left or right cursor key is pressed down, or the jog dial  4  is rotated, one of the time displaying portions arrayed in the left-and-right direction on the operation time display unit oti, that is the year, month, day, hour, minute and the seconds, may be selected to the activated state. 
     If the time is increased/decreased by operation of the mouse fitted with the wheel, it is possible to detect e.g., the continuous operation of a keyboard, rotational speed of the wheel of the mouse fitted with such wheel or that of the jog dial to change the time advancing or time lagging responsive to the detected results in an accelerating fashion. This provides for facilitated movement to the target time. Meanwhile, if the time increasing/decreasing step selecting function is implemented by the rotation of the mouse fitted with the wheel or the jog dial, it is necessary to set the environment for affording the rotation of the mouse fitted with the wheel, or the jog dial with the selecting function for the time increasing/decreasing steps. 
     The menu button mb is used for demonstrating the entire operating menus relevant to a project, such as file, addition of new labels or time labels. If the menu button mb is pressed (clicked), operating menus, such as file, addition of new labels, time or label are displayed as the pull-down menu in the vicinity of the menu button MB. Meanwhile, when the right button of the mouse is clicked in each part of the time view console TVC, or the application key is pushed with focussing, menu items (context menu items) are displayed as when the menu button MB is clicked. The pull-down menu activated on clicking the menu button mb on the time view console and the context menu by the application key will be explained subsequently in detail. 
     The closure button cb is a button for commanding closure of the time view console. 
     The help button hb is used for commanding the display of the help window used for checking into unclear points when a user acts on the label software of the present embodiment. 
     The rotation animation unit ra is used for visually demonstrating the time shifting to the user by animation display in such a manner as to rotate the rotation animation unit ra with changes in the operation time. The direction of rotation is reversed when the time proceeds to future from that when the time proceeds to past.  FIG. 38  shows only the vicinity of the rotation animation unit ra on the left end of the time view console TVC in the bar state. If attention is directed to the → portion in the drawing, it may be seen how the rotation animation unit ra is rotated in the sequence of (a), (b) and (c) in  FIG. 38 . By making the animation display in which the rotation animation unit ra is rotated in this manner, it is possible to permit the user to recognize how the time is changed. 
     The floating-state window of the time view console TVC shown in  FIG. 37  is made up of a window title portion wt, for indicating the title of the window, the time view console in the instant embodiment, a window menu unit wm for displaying the operating menu pertinent to the project, such as file, addition of new label, time, label or help, the Christian era gauge unit cg, similar to that in the bar state window, a current button bb, an operation time display unit oti, an up-down button tub and tdb, time increasing/decreasing step selection list box ssl, and a time increasing/decreasing step selection menu button sb. Meanwhile, the closure button for commanding the closure of the time view console in the case of  FIG. 37  is an “X” button. The window menu unit wm of the time view console in the floating state will be explained subsequently. 
     The screen structure of an icon IL of the label software of the present embodiment, as demonstrated on the task tray TT of the task bar TB on the desktop screen, is hereinafter explained. 
     If, as the cursor is moved on the icon IL of the label software displayed on the task tray TT, the clicking by pressing the left button of the mouse is repeated, the label software of the present embodiment alternately repeats the “all display” state and the “all hide” state of the label. If the cursor is moved on the icon IL, and the left button of the cursor is pushed twice by way of double clicking, the label software of the present embodiment performs the default operation pre-set by the user by e.g., the environment setting, such as addition of new labels, addition of new labels and the sound recording, addition of new labels and acquisition of captured picture or entrance to the time view mode. If, as the cursor is moved on the icon IL, the right button of the mouse is clicked, the label software of the present embodiment displays the entire operating menu for the project of the label software.  FIGS. 39 to 42  show an illustrative display of an operating menu when the state of “all display” is specified for the label in the normal mode, an illustrative display of the operating menu when the state of “all hide” is specified for the label in the normal mode, in the present mode, an illustrative structure of a desktop screen in the past mode and an illustrative structure of a desktop screen in the future mode, respectively. 
     The icons IL are adapted for being different in color in the present, past and future modes. The icons of different designs are displayed in the “all hide” state and “all display” state for the present mode. For example,  FIGS. 43(   a ), ( b ) and ( c ) show an example of the icon IL of the present mode, an example of the icon IL of the future mode and an example of the icon IL in the “all hide” state, respectively. This permits the user to know the current state visually without opening the menu on the task tray TT (menu of  FIGS. 39 to 42) . The menu in the icon IL on the task tray TT will be explained in detail subsequently.

If setting of the label software is made so that the time of preparation will be displayed, the time of preparation is introduced. With the item “sound label”, it is possible to prepare the label and to place it on the desktop. Sound recording is started as soon as the label is prepared. If setting of the label software is made so that the time of preparation will be displayed, the time of preparation is introduced. With the item “from capture picture”, it is possible to acquire the capture picture from the retrieving application of the capture picture, to prepare the label using the picture and to place it on the desktop. If setting of the label software is made so that the time of preparation will be displayed, the time of preparation is introduced. With the item “from clipboard”, it is possible to prepare a new label from data on the clipboard to place it on the desk top. The form of the clipboard that can be handled here is the memo from the text, picture and from the handwriting application. If setting of the label software is made so that the time of preparation will be displayed, the time of preparation is introduced. If the data from the clipboard is the text, the time of preparation is displayed on the leading line and the text in the clipboard is displayed from the second and following lines. With the item “from import file”, it becomes possible to prepare a new label from the file data to place it on the desktop. The form of the file form that can be handled here is the memo from the text, picture, sound and from the handwriting application. If setting of the label software is made so that the time of preparation will be displayed, the time of preparation is introduced. 
     With the item “time view mode”, it is possible to switch the display/non-display of the time view console. 
     With the item “time view sound”, it is possible to switch the on/off of the sound generated during the time view mode.

     With the item “label software”, the version information etc of the label software can be displayed. 
     With the item “end”, the label software can be brought to a close. 
     With the label software of the present embodiment, “operation on a project”, “operation on a label”, “operation on a time view”, “operation on a keyboard/mouse” and “operation on a jog dial” are possible. 
     The operation on a project” is first explained. 
     A project manages the entire labels belonging to the project. The label software of the present embodiment is so formulated that a project will necessarily be opened on actuation. 
     In the light source of the present embodiment, project is formulated on initial startup and when a new project preparation is selected from a menu. When preparing a new project, the project name is set and, if there is any pre-existing project, such project is closed to open a new project. 
     A project is made up of a project file, a label file or a project archive file. The project file has the information on the entire project and a label list, there being one project file for each project. 
     The label file has the information for individual labels, such as object information, there being one label file for each label. The project archive file is the project information and the information on plural labels contained in the project, and is prepared when exporting the project. The contents are a project achieve prepared at the outset, such that, when preparing a project, the contents can be contained in the newly prepared project. The project file and the label file belonging to the project file are present in one folder. 
     When preparing the project, a dialog shown for example in  FIG. 44  is displayed. The user enters a project name by this dialog. In this figure, the project name is the name of the lowermost folder of the project, and is entered as the project file name. Meanwhile, the pre-existing project name cannot be used. As the project name, a project comment containing up to a maximum of 127 letters can be entered. 
     When preparing the project, the folder of the project name is formulated and a project file is prepared therebelow. The as-prepared project has no labels. However, if designation is made to include the contents, the label information is captured from the archive. The operation of capturing the contents is the same as the import of the project as later explained. When preparing the project, the time information at the time of the project preparation is recorded as the internal data. 
     The project is opened on startup of the light source of the present embodiment or on designation from the console menu. Meanwhile, on startup of the label software, the project opened at the time of previous termination is opened. When the project is opened, the label belonging to the project is displayed on the desktop based on the time information and the position information. Two or more projects cannot be opened simultaneously, so that, if there is any opened project, such project is closed. 
     When the project is closed, the currently opened project is closed. At this time, the labels belonging to the opened project are closed. 
     The project import means adding the entire labels contained in another project in the archive form to the currently opened project. In importing the project, the file dialog is first opened on designation of the import menu. By this file dialog, the project archive file which the user desired to add is designated. On selection of the project archive file, a filter for checking the archive type is executed. The archive type of the label encompasses three types, namely “no correction”, “set the current time as start time” and “ask user as to start time”. Meanwhile, the archive type “no correction” is directly imported, without correcting the archive information. 
     When inquiring the user about the start time, a dialog specifying the input time and the minimum time units to be specified, as shown in  FIG. 45 , is displayed as the dialog for time setting for import. The user enters the start time by this dialog. 
     When the start time is inputted by the user by the dialog shown in  FIG. 45 , the dialog shown for example in  FIG. 46  is opened after executing the file. The dialog shown in  FIG. 46  is an import dialog of the project displaying the project information. When the import is executed, the data of the entire labels of the selected project archive file are copied in the currently opened project, along with the label file. 
     If there are such files for import having the same hysteresis as that of the label present in the current project, or if the entire hysteresis of one of the labels are fully coincident with the partial hysteresis of the other label, there is displayed a dialog designating the importing method, as shown for example in  FIG. 47 . On the dialog of  FIG. 47 , it is displayed whether both labels are identical or which one of the labels has a longer hysteresis. In the example of  FIG. 47 , it is possible to select a desired one of the respective items from the items “no labels are imported”, “label overwriting with the import file” and “prepare label copies”. 
     In the label software of the present embodiment, the labels contained in a project can be collectively saved in a sole archive file, that can be captured into another project, as the project export. In exporting the project, the dialog of the export of the dialog shown for example in  FIG. 48  is displayed on the desktop. On the dialog of  FIG. 48 , respective settings “export file name”, “is the export file deleted from the current project?” and “are all labels exported or are labels the generating and deleting time points are both included in the specified time range to be exported?” are made to prepare a project archive file. At the lower and of the picture of the dialog is displayed the number of the labels to be exported. The label export here means exporting the entire hysteresis of the label. 
     If then the user selects the project property, the label software of the present embodiment displays the dialog shown for example in  FIG. 49  on the desktop. In this dialog, such items as “project holder”, “project command”, “project preparing time and ultimate updating time”, “number of labels (total number, past, present and future)” and “range of existence of labels” are displayed. In the “project folder” is displayed the project folder name, whereas, in the “project command”, the explanation on the project asset on new preparation is displayed. The information in this “project command” can be edited. The “range of existence of labels” denotes the range of existence of labels, specifically, the range from the oldest hysteresis of the entire labels (time of preparation of the oldest label) up to the latest hysteresis. If there is any label the time of deletion of which is not specified, a check mark is attached to the item “there is a label the time of deletion of which is not specified”. 
     The “operation on the label” is explained. 
     As the “operation on the label”, such operations as “new preparation”, “addition of objects”, “correction of object”, “layout”, “arraying”, “property”, “import and export of object” and “label deletion” are possible. 
     With the “new preparation”, among the operations on the labels, an object inserted first can be specified when newly preparing the labels. Among the labels, newly prepared, there are “text level”, “sound level”, “from capture picture retrieving software”, “from clipboard” and “from import file”. In the newly prepared labels, the label preparing time, as a text object, is displayed in addition to the above object. Meanwhile, whether or not the time of preparation is to be displayed can be set by the setting picture. Each object is displayed in accordance with the default layout as later explained. A label file for storing the information on a label is prepared simultaneously with the new preparation of the label. 
     The “new preparation” includes new preparation for the future mode. That is, in the time view mode, labels prepared in future (future labels) can also be added. In the new preparation for the future mode, when the new preparation of the label is selected by a user, a property picture for the new label, shown in  FIG. 50 , is displayed. When the user sets the label start time, label end time, repetition and alarm, the future label can be newly prepared. Meanwhile, the default value of the display time of the property picture of  FIG. 50  is the operation time at the time point and continuation is checked (on). 
     In the operation for the label “object addition”, an object can be added to the label currently displayed. For newly inserting an object, the respective menu items “text”, “sound”, “picture”, “handwriting memo” and “link” are specified by the user from the menu button on the label. In the menu item “text”, respective operations of text editing, pasting, import file, and drag/drop operations are possible, whereas, in the “sound” menu item, respective operations of recording, importing files and drag/drop operations are possible. In the menu item “picture”, respective operations of shot, pasting, importing files and drag/drop operations are possible, whereas, in the “handwriting memo” menu item, the operation of pasting is possible. In the menu item “link”, respective operations of link editing, pasting, importing files and drag/drop operations are possible. Meanwhile, two or more objects cannot exist for a sole label. 
     In the operation on the label “object addition, “object addition by drag/drop”, “addition of object position and size” and “addition at the time of time view”. 
     In the “object addition by drag/drop”, if the file icons of the text, sound and the picture are dragged and dropped in sites other than the label link button, respective objects are inserted into the label. On the other hand, if an optional file icon is dragged and dropped on the label or on the link button, as e.g., the control key and the shift key on the keyboard are pushed simultaneously, the path of the file is added as the link object. 
     In the “addition of object position and size”, the size and the position of the added object follow the parameters of the default layout. If the test object and the picture object are set so as not to overlap with each other and if one of the objects is added newly, it is inserted below the pre-existing object. 
     In the “addition at the time of time view”, if the time view mode is the present mode, the operation similar to that for the normal mode can be made. If the time view mode is the future mode, an object can be added to the future label. As to the operation of object addition, only ultimate results are recorded and become the initial setting for the label display. As for the label that cannot be added, the label frame is displayed in a purple color (present level) or in a blue color (past level). 
     In the operation on the label “object correction”, “text correction”, “sound correction”, “picture correction”, “correction of handwriting memo”, “link correction”, “correction in time view mode” and “pasting from clipboard” are possible. 
     In the “text correction”, if the text editing item is selected by the user from the menu button MB, or the context menu mb, and the menu is selected, the editing dial having the present text as shown for example in  FIG. 51  is opened. In the dialog of  FIG. 51 , there are menus “file”, “edit” and “insert” in the text editing menu. The “file” has such items as “import file” and “text editing end”, such that, in the “import file”, the text file can be selected and inserted, whereas, in the “text editing end”, the text editing can be closed to reflect the text contents in the label. In the menu item “edit”, there are such items as “reset”, “clip”, “copy”, “paste”, “delete” and “select all”. In the menu item “insert”, there are such items as “current time and date” and “time and date of preparation”. In the “current time and date”, the time and date of the present (real time) is inserted, whereas, in the “time and date of preparation”, the label preparing time is introduced. 
     The “sound correction” is possible when the user selects the recording with the menu button MB or the context menu. There is displayed on the label a tool chip TCe indicating the recording time and the maximum recording time, as shown in  FIG. 52 , whilst the play button PB is changed to the recording button RB to advise the user of the fact that recording is going on. If the recording button RB is pushed during recording, the recording is paused and, if the recording button RB is pushed again, the recording is performed as from the paused point. In the “sound correction”, the existing sound data is overwritten. 
     In the “picture correction”, it is not possible with the label software of the present embodiment to correct the pre-existing picture object. For changing (correcting) the picture, a picture object is introduced to take the place of the pre-existing picture object. 
     For directly correcting the handwriting memo prepared by the handwriting application, for performing the “correction of the handwriting memo”, the handwriting application start is selected from the menu button MB or the context menu. After editing by the handwriting application, pasting of the edited memo in the menu button MB or the context menu is selected and newly introduced into the label. 
     The “link correction” is enabled by the user selecting the link editing item from the menu button MB or the context menu. That is, when the user selects the item of link editing, the label software of the present embodiment displays an editing dialog, having the current link, as shown for example in  FIG. 53 , on the desktop. The editing dialog of the link has an editing box EB and a file reference button. In the dialog editing box EB are stated URL such as the paths of the file or folder and the home page address. For example, if the “file reference button” is pushed, the file dialog is displayed. By selecting the file to which the link is desired to be produced, the path to the file is inputted to the edit box EB. The menu item of the dialog box of the link includes “file” and the “edit”. The menu item of the “file” includes such items as “reference” and “end of link editing”. The item “reference” is selected from the file dialog and is the same as the file reference button. The “end of link editing” closes the link correction picture to reflect the link contents in the label. The menu item “edit” includes such items as “reset”, “clip”, “copy”, “paste”, “delete” and “select all”. These contents are standard operations and are not explained specifically. 
     As the “correction at the time of time view mode”, it is possible to correct the object for the label newly displayed for the future in the time view mode. As for the object correction operation, only the ultimate results are displayed to effect initial setting at the time of label display. 
     In the “pasting from clipboard”, the text, bitmap picture, WAVE file and the handwriting memo in the clipboard can be pasted on the label. If only one object that can be pasted on the label is present in the clipboard, it can be pasted on the label. If two or more objects that can be pasted on the label are present in the clipboard, a dialog such as one shown in  FIG. 54  is displayed on the desktop. Here, a check box of data present in the clipboard is enable for display and checked data is pasted as a label object. 
     The “layout” for the label is determined with the default layout as a reference. It is noted that this setting of the default layout is utilized during label preparation and during addition of new objects. The default layout may also be used when the user manifestly selects the re-layout command. 
     In the default layout, there are parameters such as “label size (X×Y)”, “text margin (left end, upper end, right end)”, “picture margin (left end, upper end, right end”, “layout to evade the text overlapping with the picture” and “setting as to size change (re-layout and keep picture aspect ratio)”. The “label size” is used so that the horizontal direction will be of the maximum size and the vertical direction will be of the minimum size. The “text margin” and “picture margin” are defined as in  FIG. 55  and set by the dialog shown in  FIG. 56 . The vertical size of each object in the vertical direction is determined and stretched/contracted by the object data. If, as a result of stretching and contraction, the text object overlaps with the picture object, the lower object can be moved further downwards to evade overlap (setting item: layout to evade overlapping of the text with the picture). 
     For the operation when the label size is changed, there are two settings. One of these settings (re-laying out) is to lay out the object again if the label size is changed. In the absence of setting, the size of the internal object is not changed despite size changes in the label. The second setting (keeping the picture aspect ratio) is the setting as to whether or not the aspect ratio is to be kept in case there is change in the picture size. The above setting is made in a default label layout picture of the setting dialog of the present embodiment of the label software shown in  FIG. 56 . This setting may be made by displaying and dragging a sample, in place of inputting a numerical figure, as shown in  FIG. 57 . 
     With the present embodiment of the label software, layout can freely be customized by a user from one label to another in place of the default layout. For example, if a custom layout item is provided as the menu item, and the custom layout is executed, the label L is displayed as shown for example in  FIG. 58 . There is drawn a dotted-line frame circumscribing each object and the mouse can be dragged and dropped within this frame for movement. Moreover, with the present embodiment of the label software, the object size can be changed. For changing the size, the object is clicked to the selected state, in which state the label frame line is changed from a dotted line to a solid line. In addition, handles (e.g., a black small square) is displayed in the four corners and on the four sides. These handles can be dragged and dropped to change the object size. 
     Meanwhile, in the label software of the present embodiment, if, in changing the label size, automatic stretching and contraction is on and the aspect keeping is on, left and right margins are always kept constant unless the picture is of the minimum size. On the other hand, the margins at the four corners of the text are kept at constant values. In this case, the four corner margins may transgress the label window in the vertical direction of the picture in order to keep the picture aspect ratio. If the automatic stretching/contraction is on and the keeping of the aspect ratio is off, the four corner margins are always kept constant unless the text and the picture are of the minimum size. Also, if the automatic stretching/contraction is off and the aspect ratio is on or off, the text and the picture may transgress the label window. If, in all of these cases, the default layout is selected, the label size or the left-right margins and the upper margin are set at default values. The heights of the label, text and the picture are automatically adjusted to values which are sufficient to display the picture. The values which are sufficient to display the picture are those with which all pictures can be displayed. The values which are sufficient to display the text are those with which all picture portions can be viewed with the correct aspect ratio. A lower margin of the same size as the upper margin is added to the label. 
     The “arraying” of the operation on the label includes “arraying at the left end of a picture”, “arraying at the upper end of a picture” “arraying at the right end of a picture” and “arraying at the lower end of a picture” as sorts of arraying. In the “arraying at the left end of a picture”, labels are arrayed side-by-side from the upper left end of the picture in a downward direction. When the lower end of the picture is reached, the labels are arrayed in similar manner with a shift of one row towards right. In the “arraying at the upper end of a picture”, labels are arrayed side-by-side from the upper right end of the picture in a rightward direction. When the rightward end of the picture is reached, the labels are arrayed in similar manner with a shift of one row downwards. In the “arraying at the right end of a picture”, labels are arrayed side-by-side from the upper right end of the picture in a downward direction. When the lower end of the picture is reached, the labels are arrayed in similar manner with a shift of one row towards left. In the “arraying at the lower end of a picture”, labels are arrayed side-by-side from the lower left end of the picture in a rightward direction. When the rightward end of the picture is reached, the labels are arrayed in similar manner with a shift of one row upwards. The labels are arrayed in the sequence in which the labels are registered in a project label list (in the time order of preparation). The labels are arrayed so as not to be overlapped with one another, with the label size being not changed. 
     In the “property” of the operation on the labels, the property dialog of the label, such as is shown in  FIG. 50 , is displayed. The property display contents include “label number”, “number of times of hysteresis”, “term of validity”, “setting of repetitive labels” and “alarm setting”. In the “label number”, a label number unique in the project is displayed. This label number is managed by the label software of the present embodiment and cannot be changed by the user. The “number of times of hysteresis” displays the number of times of correction as from the time of the label preparation. The “term of validity” includes the “time of preparation” and “time of deletion”. The “time of preparation” displays the label preparation time. This “time of preparation” cannot be changed except at the time of preparation of a future label. The “time of deletion” is valid only when the continuation is checked. The, “setting of repetitive labels” includes such items as “interval and unit of repetition”, “next display start time” and “next display end time”. The “alarm setting” includes “time of alarm startup”. 
     In the label software of the present embodiment, the following setting contents of the “continue/discontinue”, “repetition setting” and “alarm setting” for the labels can be changed in the label property picture. If, in the item “continue/discontinue”, the setting is for “discontinue”, the label deletion time can be specified. When the time is the specified time, the label is deleted automatically. If, in the item “repetition setting”, the “periodic repetitive label” is checked, repetition setting is made. Moreover, in the item “repetition setting”, the interval of repetition, display start time and display end time can be set. In the item “alarm setting”, the alarm display time is set at the relative timing relative to the label start time. Meanwhile, the real alarm time is displayed below the alarm setting. 
     In the label software of the present embodiment, display/non-display can be repeated at regular intervals for the same label. For label repetition, “periodic repetition label (periodic repetition)” is checked in the label property picture of  FIG. 50  and the repetition interval, repetition display time and non-display time are set. For example, if a label is to be displayed for five minutes at 12.00 every day, the following setting is used: 
     repetition: every day 
     next display start time: YYYY/MM/DD (current date) 12:00:00 
     next display end time: YYYY/MM/DD (current date) 12:05:00 
     If, in the label software of the present embodiment, setting is made so that each frame picture of a moving picture is pasted on each of plural labels and so that each label will be sequentially displayed at the same position for a short time, animation-like display becomes possible. 
     Moreover, in the label software of the present embodiment, the user may be apprised of an alarm event before or after start of a specified label. For making the alarm notice, an alarm is checked on a property screen of the label of  FIG. 50  to set the alarm time. If the alarm time is set in this manner, an alarm dialog, shown in  FIG. 59 , is displayed on the desk top when the time is the time specified on the alarm. On this alarm dialog are displayed the alarm time and the label preparation time. By acting on this alarm dialog, the user is able to make selection whether the alarm is to be turned off or issued once more. If, the item “time-view the label preparation time after closing the dialog” in the dialog of  FIG. 59  is checked and the OK button is pushed, the time view mode is initiated and the operating time is set to the label preparation time. 
     Then, as the operation for the label “object import/export”, the label is able to import and display the text, sound and the picture file. The operation on importing is similar to that when adding and correcting an object. The label object is also able to take out only data as an export file. Among the forms of the file which each object is able to import and export, there are “text: text form (extender: .txt.)”, sound; WAVE form (extender:.wav)“ ”, “picture; bit map form (extender:.bmp)”, “GIF form (extender:.gif)” and “JPEG form (extender:.jpg)”. In exporting, an object for exporting is determined based on the extender of the export file. 
     Among the “label deletion” as an operation on the label, there are deletion of the present label and deletion of deletion of a future label. 
     If deletion of the present label is selected, the current time is recorded as the end time and deleted from the picture. However, the label file is not deleted such that the label can be displayed by reversion to the past by the time view mode. If the label is deleted in the future mode of the time view mode, a dialog as shown in  FIG. 60  is displayed to permit selection between setting the operating time to the end time or deleting the label at the current time. 
     If deletion of the future label is selected, the dialog of deletion of a future label as shown in  FIG. 61  is opened to render possible the selection between the setting of the operation time to the end time and the complete deletion of the file. If the label is completely deleted, the label file and recording are deleted such that these cannot be displayed again even in the time view mode. 
     The past label is already deleted and hence cannot be deleted further. 
     The “operation of time view” is now explained. 
     In the time view mode, the above-mentioned time view console TVC is displayed. The time operation in the time view mode is done from this time view console TVC. The transition to the time view mode is performed by displaying the time view console TVC by executing a command from a context menu of the label software icon IL of the time tray TT or from the label menu. 
     After transition to the time view mode, time increase/decrease can be executed by operating the up/down button tub, tdb of the time view console TVC or from the menu. The unit of time change by this time increase/decrease is by the setting of the above-mentioned time increasing/decreasing unit (time increasing/decreasing step). 
     With the label software of the present embodiment, the label preparation to the past/past label correction cannot be made. Although the past label cannot be corrected, label movement/label size change can be made. However, this operation is not recorded in the project. Also, directly after the end of the operation, such as directly after the end of the mouse drag, the label is restored to the original position/original size. This operation is performed for transiently changing the movement/size change for viewing the label hidden by superposition. 
     Moreover, in the label software of the present embodiment, a new label can be prepared as a future label distinct from a past label. If a future label is prepared, and the time is restored to the present, the label disappears from the desktop. However, when the time is the time when the future label was prepared, the label is again presented on the desktop. So, the future label can be prepared as a simple reminder. The future label can be corrected in the same way as at the present time. However, the hysteresis of correction is not recorded, in distinction from the case of the current time, such that only the corrected ultimate results are saved. Thus, should there be made correction for future, the ultimate results are used as parameters at the time of label preparation. 
     The end of the time view mode is achieved by pressing the closure button cb of the time console TVC or selecting the “close time view console” from the menu. 
     The on/off of the time view sound, furnished during the time view mode, during transition to the time view mode and on termination of the time view mode, may be achieved from the menu. 
     The operation on the “keyboard/mouse” is explained. 
     With the label software of the present embodiment, a variety of shortcuts are set as an operation proper to a keyboard. 
     For example, if the control key and the shift key are pushed simultaneously, or if the shift key, control key and the tab key are pushed simultaneously, the operation of changing the vertical orientation on the window of the labels displayed on the present picture is realized. Meanwhile, the operation at this time is changed with the number of the presently existing labels. For example, of there is not more than one label, no operation occurs. However, a pre-set sound is issued to indicate that the operation is invalid. If there are two or more labels, the control key and the tab key are pushed simultaneously to shift the label lying at the most forward position to the most backward position. Also, if the shift key, control key and the tab key are pushed simultaneously, the label at the most backward position is shifted to the most forward position. 
     For example, if the delete key is pushed, the presently focussed label is deleted. Before deleting the label, a dialog for inquiring whether or not the deletion is to be made is displayed on the dialog. 
     Of an escape key is pushed, the presently focussed label is temporarily set to the non-displayed position. The label in the non-display position is again displayed when next the time is changed. 
     When the control key and the B key are pushed simultaneously, the console is closed during the time view mode. Of the control key and the D key are pushed simultaneously, the presently focussed label is again laid out by default. When the control key and the E key are pushed simultaneously, the text editing of the presently focussed label is opened. If the control key and the L key are pushed simultaneously, the link of the presently focussed label is opened. If the control key and the N key are pushed simultaneously, the text label is prepared. When the control key and the O key are pushed simultaneously, the sound of the currently focussed label is stopped. When the control key and the P key are pushed simultaneously, the label of the currently focussed label is reproduced. When the control key and the R key are pushed simultaneously, the label of the currently focussed label commences to be recorded. When the control key and the T key are pushed simultaneously, the time view mode is entered/exited. When the control key and the V key are pushed simultaneously, the contents of the clipboard are pasted on the currently focussed label. When the control key and the down key/the control key and the up key are pressed simultaneously, the time in increased/decreased by the time view. When the control key and the left key/the control key and the down key are pressed simultaneously, the time increasing/decreasing steps are varied. When the control key and the home key are pushed simultaneously, reversion is made to the current time by the time view mode. 
     With the label software of the present embodiment, as the operation on the mouse, in particular the mouse fitted with the wheel, “operations on the label”, “operations on the time view console” and “operations on the desktop of the time view mode” are set. 
     Among the “operations on the label”, there are such operations as “drag and drop for a label”, “drop to a label from another application”, “right click for a label”, “wheel rotation for a label”, “wheel click for a label”, “drag and drop to a label (excluding the link button) for a file icon”, “drag and drop to a label (excluding the link button) for a control key, shift key and a file icon” and “drag and drop on a link button for a file icon”. In the operation of “drag and drop for a label”, labels are moved. In the operation of “drop to a label from another application”, an object is pasted to a label insofar as data recognized by the present embodiment of the label software is concerned. An error dialog is displayed insofar as data not recognized by the present embodiment of the label software is concerned. In the operation of “right click for a label”, the context menu dependent on the clicked object is displayed. In the operation of “wheel rotation for a label”, the forward/backward relationship of the labels is adjusted. In the operation of “wheel click for a label”, the time view console is displayed to transfer to the time view mode. In the operation of “drag and drop to a label (excluding the link button) for a file icon”, texts, pictures and sound files are inserted as objects. If a file cannot be recognized as an object, an inquiry is made as to whether or not it can be inserted as a link object for the file. In the operation of, “drag and drop to a label (excluding the link button) for a control key, shift key and a file icon” and “drag and drop on a link button for a file icon”, a path to the dragged and dropped file is inserted as a link object. If it is tried to insert a file path as a link object by drag and drop to a site other than the link button LB on the label, an alarm dialog shown in  FIG. 62  is displayed. If a button “YES” is pushed when the dialog is displayed, the processing is the same as when a file path is inserted as a link object by drag and drop on the link button LB on the label. 
     Among the “operations on the time view console”, there are such operations as “right click on the console”, “wheel rotation for the operating time display portion of the console” and “wheel rotation for a step selecting list box of the console time increase/decrease”. In the operation of “right click on the console”, the context menu is displayed. The operation of “wheel rotation for the operating time display portion of the console” corresponds to time increase/decrease. The operation of “wheel rotation for a step selecting list box of the console time increase/decrease” corresponds to change in the time increasing/decreasing steps. 
     In the operations of “operations on the desktop of the time view mode”, there are such operations as “wheel click for the desktop of the time view mode” and “right click on the desktop of the time view mode”. The operation of “wheel click for the desktop of the time view mode” corresponds to change in the time increasing/decreasing steps. In the operation of “right click on the desktop of the time view mode”, the time view context menu is displayed. 
     The “operation on the jog dial” is now explained. 
     In the label software of the present embodiment, the operation on the jog dial includes such operations as “right/left rotation of the jog dial”, “pushing of the jog dial (with the interval from pushing until release of pushing being not longer than one sec)” and “protracted pushing of the jig dial (with the interval from pushing until release of pushing being longer than one sec)”. In the label software of the present embodiment, the following functions are allocated to the operations on the jog dial. It is noted that, in the label software of the present embodiment, these jog dial operations are not globally picked at any time, but reaction to the jog dial actuation occurs when the label software is focussed. 
     For example, in a normal mode, the label software of the present embodiment reacts to the operations of “right/left rotation of the jog dial” and “pushing of the jog dial (with the interval from pushing until release of pushing being not longer than one sec)”. That is, if, in the normal mode, the operation of “right/left rotation of the jog dial” is made, the label software of the present embodiment causes the up-and-down relationship of the window of a label currently displayed on the picture. The operations at this time are changed depending on the number of the currently existing labels. If there is not more than one label, nothing occurs with the right/left rotation of the jog dial. However, a pre-set sound is issued to indicate that the operation is invalid. If there are two or more labels, and the operation for rightward rotation of the jog dial is made, the label at the most forward position is shifted to the most backward position among the labels. Conversely, when the operation for leftward rotation of the jog dial is made, the label at the most backward position is shifted to the most forward position among the labels. If, during the normal mode, the operation of “pushing of the jog dial (with the interval from pushing until release of pushing being not longer than 1 sec)” is made, the label software of the present embodiment displays the time view console to transfer to the time view mode. 
     Also, in the time view mode, the label software of the present embodiment reacts to all of the operations of “right/left rotation of the jog dial”, “pushing of the jog dial (with the interval from pushing until release of pushing being not longer than 1 sec)” and “protracted pushing of the jig dial (with the interval from pushing until release of pushing being longer than 1 sec)”. That is, if, in the time view mode, the operation of “right/left rotation of the jog dial” is made, the label software of the present embodiment corresponds to the time increase/decrease. For example, if the jog dial makes rightward rotation and leftward rotation, time proceeds in the future and past distentions, respectively. If the operation of, “pushing of the jog dial (with the interval from pushing until release of pushing being not longer than 1 sec)” is performed, the label software of the present embodiment corresponds to the change in the time increasing/decreasing units (time increasing/decreasing steps). For example, the time increasing/decreasing units are changed in the sequence of 100 years, 10 years, 1 year, 1 month, 1 day, 1 hour, 1 minute, 1 sec, 10 years, 10 years, . . . each time the jog dial is pushed. If the jog dial is rotated as the shift key is pushed, the time increasing/decreasing intervals are changed in the reverse sequence to that when only the jog dial is rotated. The time increasing/decreasing intervals selected at the time of the pushing of the jog dial can be set when setting the environment. When the operation of “pushing of the jig dial (with the interval from pushing until release of pushing being longer than 1 sec)” is done, the label software of the present embodiment closes the time view console to transfer to the present mode. 
     In the label software of the present embodiment, the operation that occurs on jog dial actuation is displayed on the desktop as the jog dial guide to present to the user the contents of the operations corresponding to the jog dial actuating state and to the jog dial actuation. That is, in the label software of the present embodiment, the jog dial guides of different contents are presented in the normal mode and in the time view mode since the functions are allocated in these modes to the jog dial actuation. 
       FIG. 63  shows an example of the jog dial guide during the normal mode and that during the time view mode. That is, in the jog dial guide during the normal mode, shown in  FIG. 63 , the contents of the functions corresponding to the “right/left rotation of the jog dial”, “pushing of the jog dial (with the interval from pushing until release of pushing being not longer than 1 sec)” are displayed as guides. In the jog dial guide during the normal mode, shown in  FIG. 63 , the contents of the functions corresponding to the “right/left rotation of the jog dial”, “pushing of the jog dial (with the interval from pushing until release of pushing being not longer than 1 sec)” and “protracted pushing of the jig dial (with the interval from pushing until release of pushing being longer than 1 sec)” are displayed as guides. 
     The setting contents in the label software of the present embodiment are hereinafter explained. In the label software of the present embodiment, “label setting”, “setting of default label layout”, “setting of sound recording”, “picture setting” and “environment setting” are possible. These setting contents are saved in a registry and used as common setting among the entire projects. 
     As the “label setting”, the label software of the present embodiment is able to set the label default values. In the label setting picture, there are “default background color”, “default font inclusive of text color”, “default word-wrapping state”, “display preparation time” and “apply text color only to text”, as shown in  FIG. 65 . In the “default background color”, the background color of the newly prepared label is set. In the “default font inclusive of text color”, the font of the newly prepared label is set. In the “default word-wrapping state”, it is set whether or not the word-wrapping is to be applied to the newly prepared label. In the “display preparation time”, it is set whether or not the preparation time is to be displayed on the newly prepared label. In the “apply text color only to text”, it is set whether the background color is to be applied to the entire label or only to the text. In the lower part of the label software setting picture, a sample of the label state in the current setting is displayed. 
     In the “default label layout”, default layout in the above-mentioned layout portion is made. 
     In the “setting of sound recording”, various parameters for sound recording are set. The setting contents include such items as “sound source”, “quantization level”, “sampling frequency” and “maximum recording time”. With the “sound source”, monaural/stereo setting is possible, whereas, with the “quantization level”, and “sampling frequency”, the setting of 8 bits/16 bits and the setting of 11.025 kHz, 22.05 kHz and 44.1 kHz are possible, respectively. 
     In the “picture setting”, the picture during use of the capture picture retrieving application is set. The setting contents include “operation on pushing the capture retrieving button”, “format of a picture retrieved from a capture picture retrieving application” and “setting of JPEG compression”, as shown in  FIG. 67 . The operation of “operation on pushing the capture retrieving button” includes such items as “retrieve picture in a presently selected label” and “retrieve picture in a new label”. In “retrieve picture in a presently selected label”, an inquiry is made whether or not a new label is prepared if no label is selected. In the “retrieve picture in a new label”, a new label is prepared to retrieve the picture in a new label. In the “format of a picture retrieved from a capture picture retrieving application”, there are such items as “bitmap” and “JPEG”. In the “bitmap”, H compression is not applied so that the picture is saved in its original state. In the “JPEG”, compression is applied, however, the disc capacity can be reduced. In the “JPEG setting”, the compression ratio of the retrieved picture is set when the “JPEG” is set in the “format of a picture retrieved from a capture picture retrieving application”. The compression ratio ranges between 1/1 to 1/64. 
     In the “environment setting”, “default command”, “startup” and “time increasing/decreasing interval” are set. In the “default command”, “add new label”, “add new label and record the sound”, “add new label and acquire picture from the capture picture retrieving application” and “enter into time view mode” etc. In the “startup”, it is set whether or not the registration in the startup is to be made. In the “time increasing/decreasing interval”, the time increasing/decreasing intervals (time increasing/decreasing steps) selected on pushing the time increasing/decreasing step selection menu button sb is set. The time increasing/decreasing interval not set here is not unusable and can be selected by selection from a combo-box or on clicking a date letter string. The time increasing/decreasing interval checked here are marked with “*” on the right side of a letter in the time increasing/decreasing step selection list box ssl as discussed above. 
     With the label software of the present embodiment, having the above-mentioned functions, the entire operations on the labels on the desktop are saved to enable reproduction of label states at an optional time point. For saving the label states on the desktop, a method of saving the entire information of plural labels at a given time point and a method of saving only the difference of the label information at a time point may be used. The label states may be saved periodically at regular intervals or at time points when changes are made in the labels. For saving the differences in the label information, the operations on the label, that is the operating hysteresis, are saved, or the difference of the label information before and after operations on the label, that is the variance in the label information, may be saved. 
     With the label software of the present embodiment, having the above-mentioned functions, not only the operations on the present label, but also the future operations, may be appointed to enable labels (future labels) to be used as reminders. The operations on the future labels are determined when the current time is the time set in the future level. Therefore, the hysteresis as to the operations on the future labels is not saved but only the information on the last operation is saved. Although the future label may also have the hysteresis, plural futures exist in this case. This surpasses the range of human understanding. For this reason, the present embodiment does not set the hysteresis for the future labels. For appointing the operations for future labels, repetitive operations of the label display/non-display may be envisaged in addition to the operation such as simple label preparation. 
     Moreover, in the label software of the present embodiment, having the above-mentioned functions, in which the label has the concept of time, it is possible to associate a label with an alarm to ring an alarm when the time is the pre-set time. This alarm rings irrespective of the current desktop display time, such that, even when the state of past or future label states are displayed, the alarm is rung to avoid the risk of overlooking crucial label information. Meanwhile, an alarm to a label can be attached to each label. In distinction from a usual alarm, the present alarm can be rung not only before the preparation time but also after label preparation. Moreover, an alarm can be rung even to the selected alarm. For this reason, the alarm can be rung after 1 year so that an alarm can be rung after lapse of a year from an anniversary. 
     Referring to  FIGS. 69 to 72 , the processing flow in the CPU  51  in case of implementing the above process by a personal computer is explained. 
       FIG. 69  shows the overall flow of the reproducing processing of the label states at an optional past time point, the reproducing processing of the appointment for operations for future labels and alarm processing. If the label software is started at step S 131 , the CPU  51  records the processing at step S 132  in case some operation or other is performed on the label. If the alarm setting is made, the alarm processing is performed at step S 133 , whereas, if setting for repetition is made for a label, the label updating processing is performing at step S 134 . The CPU  51  then verifies whether or not each processing has come to a close. If the result of check is YES, the CPU reverts to step S 132  and, if otherwise, the CPU moves to step S 136 . The CPU  51 , proceeding to step S 136 , performs the end processing of the label software. 
       FIG. 70  shows a detailed flow of the operational recording processing of step S 132 . If, in  FIG. 70 , the operating recording processing is started, the CPU  51  at step S 141  verifies whether or not some operation or other has been done on a label by the user. If the result of check is NO, the recording processing is closed to proceed to step S 133  and, if otherwise, the CPU  51  proceeds to the processing of step S 142  to compute the label difference information before and after the processing operation. The CPU  51  then verifies at step S 143  whether the operation on the label is that on the current label (operating hysteresis) or the operation on the future label (operation appointment). If the processing is verified at this step S 143  to be the operation on the current label, the CPU  51  at step S 144  adds the current time to the label difference information to save the resulting data. if the operation is found at step S 43  to be that on the future label, the CPU  51  at step. S 145  adds the appointed time to the label difference information to save the resulting data. After the processing of these steps S 144  and S 145 , the CPU  51  terminates the operation recording processing to proceed ti the processing of step S 133  of  FIG. 69 . 
       FIG. 71  shows a detailed flow of alarm processing of step S 133  of  FIG. 69 . In  FIG. 71 , when the alarm processing is started, the CPU  51  at step S 151  verifies whether or not an alarm has been set in the label. If the result of check at this step S 51  is NO, the alarm processing is terminated to proceed to the processing of step S 134  of  FIG. 69 . If the result of check is YES, the CPU  51  checks whether or not the current time is past (or is) the alarm setting time. If the CPU verifies that the current time is past the alarm setting time, it proceeds to step S 153  and, if otherwise, it proceeds to step S 156 . At step S 153 , the CPU  51  rings an alarm and, at step S 154 , it verifies whether or not the object label corresponding to the alarm is to be displayed. If the result of check at step S 154  is NO, the CPU  51  proceeds to the processing of step S 156  and, if otherwise, it proceeds to the processing at step S 255 . At step S 155 , the CPU  51  sets the display time to the time when the object label is saved and proceeds to step S 156 . At step S 156 , the CPU  51  checks whether or not the label alarm processing has come to a close. If the result of check is NO, the CPU reverts to step S 151  and, if otherwise, the CPU terminates the alarm processing to proceed to the processing of step S 134  of  FIG. 69 . 
       FIG. 72  shows the flow of detailed processing of step S 134  of  FIG. 69 . In this figure, when the label updating processing is started, the CPU  51  at step S 161  verifies whether or not there is any label set for repetition. If the result of check is NO, the CPU  51  proceeds to step S 163  and, if otherwise, to step S 162 . At step S 162 , the CPU  51  executes label repetition processing. The CPU  51  then proceeds to step S 163 . At step S 63 , the CPU  51  verifies whether or not the current state is being displayed. If the result of check at step S 63  is NO, that is the current state is the past or future mode, the CPU proceeds to step S 165  and, if otherwise, to step S 164 . At step S 164 , the CPU  51  sets the display time to the current time and then proceeds to step S 166 . At step S 165  After setting the display time to the current state, the CPU  51  proceeds to step S 166 . At step S 165 , the CPU 51  sets the display time to the user specified time, before it proceeds to step S 166 . At step S 166 , the CPU  51  displays the state of the label of the display time as set (present, past or future mode). The CPU  51  then terminates the label updating processing to proceed to the processing of step S 135 . 
     The label software of the present embodiment, having the above-mentioned functions, realizes not only definite information, such as text or picture, to the label, but also the link function of indirectly pasting the entire information. Thus, in the label software of the present embodiment, which realizes the link function, there is no necessity of displaying the entire information in a label of a definite size, thus enabling effective utilization of the label area. That is, in the case of a label having no link function, contrary to the present embodiment, the entire information needs to be retrieved at a time point the object is pasted to the label. Meanwhile, in the label software of the present embodiment, the entire link information can be displayed in a label. By this link function, the personal computer in the started state of the label software of the present embodiment is able to display not only the information in a local machine but also the information on the network on the label. Since the information on the network can be linked and set on a label, the personal computer of the present embodiment is able to display the link contents only when the user requests execution, such that there is no necessity of the personal computer being perpetually linked to the network. 
     The processing flow in the CPU  51  in case of realizing the link function on the label by the label software of the present embodiment is shown in  FIGS. 73 to 75 . 
       FIG. 73  shows the overall processing flow in case of indirectly pasting the entire information on the label by the link. When the label software is started at step S 171 , the CPU  51  at step S 172  verifies whether or not the link has been corrected. If the result of check at step S 172  is NO, the CPU  51  proceeds to step S 174  and, if otherwise, to step S 173 . At step S 173 , the CPU  51  executes link editing processing. The CPU  51  then verifies whether or not the link is to be executed. If the result of check at step S 174  is NO, the CPU  51  proceeds to step S 176  and, if otherwise, to step S 175 . At step S 175 , the CPU  51  performs the link execution processing. The CPU  51  then checks at step S 176  whether or not the processing has come to a close. If the result of check at step S 176  is NO, the CPU  51  reverts to step S 172  and, if otherwise, to step S 177 , where the CPU  51  executes label software terminating processing. 
       FIG. 74  shows the detailed processing flow of step S 173 . In  FIG. 74 , when the link editing processing is started, the CPU  51  checks at step S 181  whether or not the link editing is done by drag and drop by e.g., a mouse. If the result of check at step S 181  is YES, the CPU  51  proceeds to step S 183  and, if otherwise, to step S 182 . At step S 183 , the CPU  51  saves the dragged and dropped file path and URL as link and then terminates the link editing processing to proceed to the processing at step S 174  of  FIG. 73 . At step S 182 , the CPU  51  displays the link editing dialog shown in  FIG. 53  before proceeding to step S 184 . At step s 184 , the CPU  51  verifies whether or not, in the above-mentioned link editing dialog, the file path of the link destination or URL has been entered or the link reference command has been issued. If it is verified that the file path of the link destination or the URL has been entered, the CPU  51  proceeds to step S 187 . If it is verified that the link reference command has been issued, the CPU  51  proceeds to step S 185 . At step S 187 , the CPU  51  saves the input file path or the URL as the link destination to then terminate the link editing processing to proceed to step S 174  of  FIG. 73 . At step S 185 , the CPU  51  displays the link reference dialog before proceeding to step S 186 , where the CPU  51  saves the referenced file path or URL as the link destination. The CPU  51  then terminates the link editing processing to proceed to step S 174  of  FIG. 73 . 
       FIG. 75  shows the detailed processing flow of the processing at step S 175  of  FIG. 73 . In  FIG. 75 , when the link editing processing is started, the CPU  51  at step S 191  checks whether or not the saved link information is URL. If the result of check at step S 191  is YES, the CPU  51  proceeds to step S 193  and, if otherwise, to step S 192 . At step S 193 , the CPU  51  opens the saved link information as URL and subsequently terminates the link executing processing to proceed to the processing at step S 176  of  FIG. 73 . At step S 192 , the CPU  51  checks whether or not the saved link information is a path to an execution file. If the result of check at step S 192  is YES, the CPU  51  proceeds to step S 195  and, if otherwise, to step S 194 . At step S 195 , the CPU  51  executes the saved link as an executing file to then terminate the link editing processing to proceed to step S 176  of  FIG. 73 . At step S 194 , the CPU  51  opens the saved link as a document file to then terminate the link editing processing to proceed to step S 176  of  FIG. 73 . 
     With the label software of the present embodiment, having the above-mentioned function, the time label for the purposes of present/past/future can be easily displayed on the desktop. 
     For moving the label time on the desktop, it may be envisaged to advance/retract the time by a pre-set interval by the user executing a sole command. This enables the information one day before or after to be retrieved easily. 
     For moving the label time on the desk top, it may be envisaged to advance/retract the time up to a time point of change of the information by a user executing a command. The time interval at this time is not constant and determined by the change point of the label information so that the movement time is variable. This enables the label information switching time point to be retrieved easily. 
     For moving the label time on the desktop, it may be envisaged to vary the time advancing/retracting manner in an accelerated manner by the user executing the consecutive commands. This enables movement to the target time easily and speedily. 
     The processing flow by\y the CPU  51  in implementing the label time movement function on the desktop by a personal computer by the label software of the present embodiment is shown in  FIGS. 76 to 78 . 
       FIG. 76  shows the overall processing flow enabling movement to an optional present/past/future time. When the label software is started at step S 201 , the CPU  51  at step S 202  verifies whether or not the time movement unit, that it the above-mentioned time increasing/decreasing intervals (time increasing/decreasing steps) are to be changed. If the result of check at step S 201  is NO, the CPU  51  proceeds to step S 204  and, if otherwise, to step S 203 . At step S 203 , the CPU  51  changes the time movement unit, that it the above-mentioned time increasing/decreasing intervals (time increasing/decreasing steps). The CPU  51  at step S 204  verifies whether or not the label time movement on the desktop has been commanded. If the result of check at step S 204  is YES, the CPU  51  proceeds to step S 206  and, if otherwise, to step S 205 . At step S 205 , the CPU  51  performs the time movement processing, that is movement to a desktop picture in the past or future mode. After the time movement processing at step S 205 , the CPU  51  at step S 206  updates the display at the set time to proceed to step S 207 . The CPU  51  at step S 207  verifies whether or not the processing has come to a close. If the result of check at step S 207  is NO, the CPU  51  reverts to step S 202  and, if otherwise, to step S 208 . At this step S 208 , the CPU  51  executes the end processing for the label software. 
       FIG. 77  shows the detailed processing flow of the processing at step S 203  of  FIG. 76 . In  FIG. 77 , when the processing for changing the time movement unit (change of the time increasing/decreasing interval) is started, the CPU  51  at step S 211  verifies whether or not the information change point unit has been set as the movement unit. If the result of check at step S 211  is YES, the CPU  51  proceeds to step S 213  and, if otherwise, to step S 212 . At step S 213 , the CPU  51  sets the information change point as the time movement intervals (time increasing/decreasing intervals or time increasing/decreasing steps) to terminate the time movement unit change processing to proceed to step S 204  of  FIG. 76 . At step S 212 , the CPU  51  sets the specified unit (100 years, 10 years, 1 year, 1 month. 1 day, . . . to terminate the time movement unit change processing to proceed to the processing at step S 204  of  FIG. 76 . 
       FIG. 78  shows the detailed processing flow of the processing at step S 205  of  FIG. 76 . In  FIG. 78 , when the time movement processing is started, the CPU  51  at step S 221  verifies whether or not the time movement is directly commanded by the above-mentioned operation time display unit oti. If the result of check at step S 221  is YES, the CPU  51  proceeds to step S 223  and, if otherwise, to step S 222 . At step S 223 , the CPU  51  sets the above-mentioned directly commanded time as the time movement interval (time increasing/decreasing interval or time increasing/decreasing step) before terminating the time movement processing to proceed to step S 206  of  FIG. 76 . At step S 222 , the CPU  51  checks whether or not the information change point interval has been set as the time movement interval (time increasing/decreasing interval or time increasing/decreasing step). If the result of check at step S 222  is NO, the CPU  51  proceeds to step S 225  and, if otherwise, to step S 224 . At step S 225 , the CPU  51  advances (or retracts) the time with the so-set time interval to then terminate the time movement processing to proceed to the processing of step S 206 . At step S 224 , the CPU  51  retrieves the next or previous change point. The CPU  51  at step S 226  verifies whether or not the next or previous change point has been found. If the result of check at step S 226  is NO, the CPU  51  terminates the time movement processing to proceed to step S 206  of  FIG. 76  and, if otherwise, to step S 227 . At this step S 227 , the CPU  51  terminates the time movement processing to proceed to step S 206  of  FIG. 76 . If the result of check at step S 226  is YES, the CPU  51  proceeds to step S 227 , where the CPU  51  sets the time as found by retrieval as the movement time to then terminate the time movement processing to proceed to the processing of step S 206  of  FIG. 76 . 
     With the label software of the present embodiment, having the above-described functions, a jog dial can be used as a user interface for label time movement on the desktop. With the use of the jog dial, the operation of advancing/retracting the time is realized by the operation of rotating the jog dial in the rightward/leftward direction to provide for smooth time movement processing operations. 
     With the label software of the present embodiment, having the above-described functions, the jog dial pushing operation can be allocated to the alteration of the advancing/retracting time interval. Therefore, the entire operations of changing the label time can be realized solely by jog dial operation, as a result of which the time change can be realized without using routine keyboard or mouse. 
     With the label software of the present embodiment, having the above-described functions, the jog dial pushing operation can be allocated not only to making change in the regular time increasing/decreasing interval in label display but also to making the above-mentioned change point movement of the label information. The result is that the time movement with the attention directed only to the information change point can be realized solely by actuation on the jog dial. 
     Moreover, with the label software of the present embodiment, having the above-described functions, the amount of label time movement can be varied depending on the rotating speed of the jog dial to render more prompt retrieval of discrete time points. 
     In addition, with the label software of the present embodiment, having the above-described functions, the jog dial pushing is used as a trigger for the time movement mode and the subsequent jog dial rotation/pushing operation is allocated to the above-mentioned time movement operation. By dividing the function between the short jog dial pushing and the long jog dial pushing, the entire operation of entering into the time movement mode/exiting the time movement mode can be realized solely by the jog dial. In this manner, the information scattered in the present/past/future can be browsed solely by the jog dial. It is noted that data correction is in need of input devices, such as a keyboard or a mouse. 
     Furthermore, with label software of the present embodiment, the time movement processing is facilitated by employing a shift key or a control key in combination with the jog dial rotating/pushing operation to execute counter-functions. If, for example, the unit of the time increasing/decreasing interval are changed from smaller to larger values, by pushing the jog dial, and the shift key or the control key is used in combination, the unit of the time increasing/decreasing interval is changed in an opposite direction to the case of using only the jog dial to facilitate selection of the unit of the time increasing/decreasing interval. 
     The processing flow in the CPU  51  in case the time movement to present/past/future is to be realized by the jog dial operation is shown in  FIGS. 79 to 82 . 
       FIG. 79  shows the overall flow in case the time movement to present/past/future is to be realized by the jog dial operation. If, at step S 231 , the label software is started, the CPU  51  at step S 232  verifies whether or not the jog dial has been thrust. If the result of check at step S 232  is NO, the CPU  51  proceeds to step S 234  and, if otherwise, to step S 233 . At step S 233 , the CPU  51  browses the information by rotation of the jog dial. At step S 234 , the CPU  51  verifies whether or not the processing has come to a close. If the result of check at step S 234  is NO, the CPU  51  reverts to step S 232  and, if otherwise, the CPU  51  proceeds to step S 235 , where the label software proceeds to terminate the label software. 
       FIG. 80  shows the detailed processing flow performed at step S 233  of  FIG. 79 . If, in  FIG. 80 , the browsing processing by the jog dial is started, the CPU  51  at step S 242  verifies whether or not the jog dial has been pushed for long time, with the interval since pushing until release of the jog dial being not shorter than 1 sec. If the result of check at step S 242  is YES, the CPU  51  terminates the browsing processing to proceed to step S 234  of  FIG. 79  and, if otherwise, the CPU  51  proceeds to step S 243 . At this step S 243 , the CPU  51  verifies whether or not the jog dial has been pushed, with the interval since pushing until release of the jog dial being not longer than 1 sec. If the result of check at step S 243  is NO, the CPU  51  proceeds to step S 245  and, if otherwise, to step S 244 , where the CPU  51  changes the time increasing/decreasing unit corresponding to the pushing of the jog dial. When the CPU  51  proceeds to step S 245 , the CPU  51  verifies whether or not rotation of the jog dial has been made. If the result of check at step S 245  is NO, the CPU  51  reverts to step S 242  and, if the result of check at step S 245  is YES, the CPU  51  proceeds to step S 246  where the CPU  51  executes time movement processing corresponding to the rotation of the jog dial. At step S 247 , the CPU  51  changes the display with the set time to then revert to step S 242 . At step S 248 , the CPU  51  terminates the browsing by the jog dial to proceed to the processing of step S 234  of  FIG. 79 . 
       FIG. 81  shows the detailed processing flow of step S 244  of  FIG. 80 . In  FIG. 81 , the CPU  51  verifies at step S 251  whether or not the shift key has been thrust. If the result of check at step S 251  is YES, the CPU  51  proceeds to step S 253  and, if otherwise, to step S 252 . At this step S 252 , the CPU  51  checks whether or not the current time interval unit (time increasing/decreasing unit or step) is the minimum unit. If the result of check at step S 252  is YES, the CPU  51  proceeds to step S 255  and, if otherwise, to step S 254 . At step S 253 , the CPU  51  checks whether or not the current time interval unit (time increasing/decreasing unit or step) is the maximum unit. If the result of check at step S 253  is YES, the CPU  51  proceeds to step S 255  and, if otherwise, to step S 256 . At step S 254 , the CPU  51  sets the next unit on the operation time display unit oti as the time movement interval (time increasing/decreasing unit or time increasing/decreasing step). The CPU  51  then terminates the movement unit changing operation to proceed to step S 245  of  FIG. 80 . At step S 255 , the CPU  51  sets the above-mentioned information change point as the time movement interval (time increasing/decreasing unit or time increasing/decreasing step). The CPU  51  then terminates the time movement unit changing processing to proceed to step S 245  of  FIG. 80 . At step S 256 , the CPU  51  sets the previous unit of the operation time display unit oti as the time movement interval (time increasing/decreasing unit or time increasing/decreasing step). The CPU then terminates the time movement unit changing processing to proceed to step S 245  of  FIG. 80 . 
       FIG. 82  shows the detailed processing flow of step S 246  of  FIG. 80 . In  FIG. 82 , the CPU  51  verifies at step S 261  whether or not continuous jog dial rotating operation has been made. If the result of check at step S 261  is YES, the CPU  51  proceeds to step S 263  and, if otherwise, to step S 262 . At step S 263 , the CPU  51  sets to perform time increasing/decreasing at an accelerated pace, that is to accelerate time increasing/decreasing, in agreement woththe continuous rotating processing of the jog dial, before proceeding to step S 262 . At step S 262 , the CPU  51  verifies whether or not the information changing point interval has been set as the time movement interval (time increasing/decreasing unit or time increasing/decreasing step). If the result of check at step S 262  is YES, the CPU  51  proceeds to step S 264  and, if otherwise, to step S 265 . At step S 264 , the CPU  51  retrieves the next (or previous) information changing point, as it takes into account the results of check at step S 261 , if the acceleration setting is made at step S 263 . The CPU  51  then proceeds to step S 267 . At step S 265 , the CPU  51  advances the time with the time interval as set, as it takes into account the results of check at step S 261 , if the acceleration setting is made at step S 263 . The CPU  51  then terminates the time movement processing to proceed to step S 267  of  FIG. 80 . At this step S 267 , the CPU  51  verifies whether or not the next (or previous) information changing point has been found. If the result of check at step S 267  is YES, the CPU  51  proceeds to step S 268  and, if otherwise, to step S 269 . At this step S 269 , the CPU  51  sets the time of the last (or first) change point as the movement time to then terminate the time movement processing to proceed to the processing of step S 247  of  FIG. 80 . 
     In the label software of the present embodiment, having the above-described functions, the time movement processing by the jog dial as discussed above can be reflected, as a jog dial guide, on the picture. Moreover, with the label software of the present embodiment, a portion of the picture (rotation animation unit ra of the time view console) can be displayed as the rotation animation, in agreement with the jog dial rotating operation, while the difference in the jog dial rotating operation can be represented by changing the direction of the rotation animation. 
     Moreover, in the label software of the present embodiment, the current time is represented by numerical figures on the operation time display unit oti, whilst the western calendar graph is represented on the Christian era gauge unit cg, so that these representations can be made in real-time. In addition, time changes is rendered more definite by scrolling the western calendar graph. Meanwhile, in the western calendar graph, the current time and the time of the label displayed on the desktop are indicated by different lines, such as with different colors, to enable the relationship between the current time and the display time to be recognized more easily. 
     Furthermore, with the label software of the present embodiment, the desktop background picture is varied with the present/past/future to render the currently feasible operations definite. For example, the situation in which correction is not possible in the past, only the label operation appointment is possible for future and all operations are feasible at present is clarified for the user by changing the desktop background picture. 
       FIGS. 84 and 85  shows the processing flow in the CPU  51  in which the displaying function of the jog dial guide or the western calendar graph is realized with the personal computer. 
       FIG. 83  shows the overall flow when the jog dial operation is used as a user interface for time movement. First, when the label software is started at step S 271 , the CPU  51  at step S 272  verifies whether or not the jog dial has been rotated. If the result of check at step S 272  is NO, the CPU  51  proceeds to step S 274  and, if otherwise, to step S 273 . At this step S 273 , the CPU  51  browses the information in keeping with the rotation of the jog dial. At step S 274 , the CPU  51  verifies whether or not the processing has come to a close. If the result of check at step S 274  is NO, the CPU  51  reverts to step S 272  and, if otherwise, to step S 275 , where the CPU  51  terminates the label software.

At step S 283 , the CPU  51  displays the rotation animation in agreement with the direction of jog dial rotation. At step S 284 , the CPU  51  performs time movement in agreement with the direction and the amount of jog dial rotation. In addition, the CPU  51  at step S 285  displays the time by the time movement processing and updates the western calendar graph. The CPU  51  then at step S 286  checks whether or not the past/present/future state has been changed. If the result of check at step S 286  is NO, the CPU  51  proceeds to step S 288  and, if otherwise, to step S 287 , where the CPU  51  updates the background picture of the desktop picture depending on its past/present/future state to then proceed to step S 288 . At this step S 288 , the CPU  51  checks whether or not the browsing processing in keeping with the jog dial actuation is to be terminated. If the processing is verified not to be terminated, the CPU  51  reverts to step S 282  and, if otherwise, the CPU  51  performs the browser terminating processing at step S 289  to then proceed to the processing of step S 274  of  FIG. 83 . 
     In the label software of the present embodiment, having the above-mentioned functions, the state whether or not the information of respective labels can be changed during information browsing in the past/present/future is displayed on a label to realize the function of enabling the label state to be presented to the user. For displaying the label state, an icon may be shown on a portion of the label. Alternatively, labels may also be fringed such as by changing the fringe color. If the number of label states is increased from two, namely the correctable state and the correction inhibiting state, for clarifying the reason for correction inhibition, the user is able to recognize the state more clearly. 
       FIGS. 85 to 87  show processing flow in the CPU  51  in case the label state presenting function is to be realized by a personal computer using the label software of the present embodiment.

When the label software is started at step S 291 , the CPU  51  at step S 292  verifies whether or not the time movement processing has been made by rotation of the jog dial, keyboard actuation or the up/down button tub, tdb. If the result of check at step S 292  is YES, the CPU  51  proceeds to step S 29 , where the CPU  51  performs an information browsing operation in keeping with the time movement processing. At step S 294 , the CPU  51  verifies whether or not the processing has come to a close. If the result of check at step S 294  is NO, the CPU  51  reverts to step S 292  and, if otherwise, the CPU  51  proceeds to step S 295 , where the CPU  51  terminates the label software.

At step S 317 , the CPU  51  sets the label state to editable (present or future label) before proceeding to step S 318 . At step S 318 , the CPU  51  checks whether or not the updating processing of the entire labels has come to a close. If the result of check at step S 318  is NO, the CPU  51  reverts to step S 312  and, if otherwise, to step S 319 . At this step S 319 , the CPU  51  terminates the label state updating before proceeding to step S 307  of  FIG. 86 .

At step S 323 , the CPU  51  starts browsing the information before proceeding to step S 324 . At this step S 324 , the CPU  51  checks whether or not the processing has come to a close. If the result of check at step S 324  is NO, the CPU  51  reverts to step S 322  and, if otherwise, to step S 325 , where the CPU  51  performs the label software terminating processing.

     In the label software of the present embodiment, the design of the icon IL of the label software on the task tray TT is made different in the present, past and future modes, and in the all hide states in the present mode, so that a selectable menu will be predicted even if the context menu is not displayed. Meanwhile, this method is useful not only in an application with time shift processing but also in any application where there is no main window and where the menu is allocated to the task tray icon. In an application where there is a main window, it is a frequent occurrence that the state can be displayed in the main window but the task tray icon is always apparent. Therefore, menu items can be predicted even if the main window is minimized in size, without the necessity of resetting the main window to its original size.

If the result of check at step S 357  is NO, the CPU  51  reverts to step S 352 , in which case the CPU  51  performs browsing end processing to then proceed to step S 374  of  FIG. 90 . 
       FIG. 92  shows the detailed processing at step S 356  of  FIG. 91 . In  FIG. 92 , when the icon updating processing is started at step S 361 , the CPU  51  verifies whether the display time is past, present or future. If the CPU  51  verifies that the display time is past, present or future, the CPU  51  proceeds to steps S 363 ,  364  or  365 , respectively. At step S 363 , the CPU  51  sets a past icon, shown in  FIG. 43   b , in the label software icon IL on the task tray TT, before proceeding to step S 366 .
