Title: Calendar timer mechanism, medical image processing system, and control program

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a calendar timer mechanism for turning on and off a controlled object at preset times and changing preset times as desired, a medical image processing system, and a control program. 
     2. Description of the Related Art 
     In the image forming field, for example, there are employed image forming apparatus for forming an image captured by an ultrasonic diagnosis, a CT diagnosis, an MRI diagnosis, or an X-ray diagnosis as a visible image on a recording medium such as a photosensitive thermal-development recording medium, for example. 
     Such image forming apparatus usually have a drum housing a heater such as a halogen lamp or the like and an endless belt trained around about two-thirds of the circumferential surface of the drum and drivable by the drum. When the drum is rotated, a photosensitive thermal-development recording medium is inserted between and fed by the drum and the endless belt. During this time, the heater is energized to heat the photosensitive thermal-development recording medium to thermally develop an image thereon into a visible image. 
     The image forming apparatus are generally installed in hospitals and other medical facilities. It is customary for such installation sites to have predetermined periods of time during which the image forming apparatus are to be operated for each of the days of the week. It is desirable to schedule times to turn on and off the power supply of the image forming apparatus for each day and automatically control the operation of the image forming apparatus according to the established schedule. 
     There has been known an automatic operation control system for automatically controlling the operation of an apparatus (see, for example, Japanese Laid-Open Patent Publication No. 6-337727). The known automatic operation control system presets times to turn on and off the power supply of the apparatus to be automatically controlled, selects subsequent times to turn on and off the power supply from the preset times, and sets the selected times in a calendar timer device. When one of the set times is reached, the calendar timer device generates a signal to control the power supply. 
     According to the above automatic operation control system, it is not necessary for the operator to perform external manual control actions each time the power supply is to be turned on and off, instead the power supply can automatically be turned on and off by setting a schedule for the power supply control timing one time. 
     The applicant of the present application has proposed a calendar timer mechanism disclosed in U.S. patent application Ser. No. 10/396,468 as an effective energy saving mechanism. The disclosed calendar timer mechanism controls a processing apparatus to easily perform efficient and economic processing operations. 
     SUMMARY OF THE INVENTION 
     The present invention has been made in reference to the invention of U.S. patent application Ser. No. 10/396,468. 
     It is an object of the present invention to provide a calendar timer mechanism which makes it possible to set times flexibly in an energy saving mode for not only weekdays but also holidays, together with a medical image processing system and a control program. 
     According to the present invention, there are provided a calendar timer mechanism, a medical image processing system including a calendar timer mechanism, and a control program for controlling the calendar timer mechanism. The calendar timer mechanism is switchable between a normal mode for supplying energy to a controlled object and at least one energy saving mode for reducing the amount of energy consumed by the controlled object, according to a timer. Based on calendar data, including weekday information and holiday information, which is capable of setting a working day and/or a nonbusiness day for each day or weekday, the amount of energy consumed by the controlled object is reduced by the energy saving mode in a preset nonbusiness time zone on nonbusiness days, and on Sundays and holidays which are not working days. 
     By setting a working day and/or a nonbusiness day for each day or weekday using the calendar data, the controlled object can be set to the energy saving mode in a preset nonbusiness time zone on nonbusiness days and on Sundays and holidays which are not working days. Thus, the amount of energy consumed by the controlled object can easily be reduced. 
     The calendar data can be set for a half-day holiday for each day or weekday, and the amount of energy consumed by the controlled object is reduced by the energy saving mode in a half-day holiday time zone included within preset information concerning the set half-day holiday. The controlled object is therefore compatible with half-day holidays. 
     If the nonbusiness time zone can be set to include an afternoon time zone of a day preceding nonbusiness days and Sundays and holidays which are not working days, and a forenoon time zone of a day following nonbusiness days and Sundays and holidays which are not working days, then the nonbusiness time zone can be extended without changing the settings for the preceding day and the following day. 
     The calendar data may be selectable from a plurality of regional data and/or yearly data having different holiday information. Thus, regional and yearly calendars can be applied to allow the controlled object to set the energy saving mode to match different holidays in various regions of the world through simple control actions. 
     If there are a plurality of processing apparatus each as the controlled object, and the calendar data with working day information and/or nonbusiness day information set therein can be shared and set by the processing apparatus, then it is not necessary to make settings for each of the processing apparatus, and the time required to make such settings is greatly reduced. 
     Summer time information including period information and offset time information may be set, and the energy saving mode may be performed at a time shifted by a time represented by the offset time information in a period represented by the period information. 
     The normal mode may comprise an ON mode for turning on the controlled object, the energy saving mode may include an OFF mode for turning off the controlled object and at least two auxiliary energy saving modes for selectively bringing the controlled object into an OFF state or a low power consumption state, and times required to shift between at least three of the modes may be set optionally. 
     Specifically, the energy saving effect of the controlled object and the rising time thereof involve countervailing factors. If a large energy saving effect is to be obtained, then the rising time becomes long. Therefore, if the preset shutdown period is long, then a mode with a large energy saving effect (a long rising time) is selected. If the shutdown period is short, then a mode with a short rising time (a small energy saving effect) is selected. Consequently, it is possible to put the energy saving effect and the rising time into a desired balance, allowing improved energy savings for the controlled object as a whole. 
     The controlled object, which is to be controlled to save energy, may comprise an image forming apparatus having an exposure unit for applying a light beam to a recording medium and a thermal development device having a heat source for developing an image on the recording medium. 
     The above and other objects, features, and advantages of the present invention will become more apparent from the following description when taken in conjunction with the accompanying drawings in which a preferred embodiment of the present invention is shown by way of illustrative example.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       FIG. 1  shows in schematic vertical cross section an image forming apparatus (processing apparatus)  10   a  incorporating therein a calendar timer mechanism according to an embodiment of the present invention. 
     As shown in  FIG. 1 , the image forming apparatus  10   a  has a casing  12  housing therein a photosensitive medium supply device  14 , an image exposure device  16 , and a thermal development device  18 , which are successively connected by a feeder  20  in the direction in which a recording medium (photosensitive thermal-development recording medium) F is to be fed. The photosensitive medium supply device  14  has a pair of upper and lower loaders  24 ,  26  each supplied with a magazine  22  housing a predetermined number of stacked recording mediums F therein. The loaders  24 ,  26  comprise respective sheet feeding means, having respective suction cups  28 ,  30 . Feed roller pairs  32  of the feeder  20  are disposed in positions for receiving recording mediums F that are removed from the magazines  22  by the suction cups  28 ,  30 . 
     The image exposure device  16  has an exposure unit  34  for applying a light beam L that is periodically deflected in a main scanning direction to a recording medium F supplied from the photosensitive medium supply device  14 , and an auxiliary scanning feeding means  36  for feeding the recording medium F in an auxiliary scanning direction (indicated by the arrow X) that is substantially perpendicular to the main scanning direction. The exposure unit  34  comprises a known light beam scanner. The auxiliary scanning feeding means  36  comprises a pair of feed roller pairs  38 ,  40 . 
     The thermal development device  18  comprises a heating drum  42 , an endless belt  44 , and a peeler blade  46 . The heating drum  42  houses therein a heating light source such as a halogen lamp or the like or a heat source such as a heater or the like. In the present embodiment, the heating drum  42  houses a heater  48  therein (see  FIG. 2 ). 
     The heating drum  42  has a surface heated to and kept at a temperature depending on the thermal development temperature of the recording medium F. When the heating drum  42  is rotated about its own shaft  42   a , the heating drum  42  and the endless belt  44  sandwich and feed the recording medium F along the outer circumferential surface of the heating drum  42 . The endless belt  44  is trained around a plurality of rollers  50  and also around a certain range of the outer circumferential surface of the heating drum  42 . 
     A tray  52  for placing thereon a stack of recording mediums F, which have been thermally developed by the thermal development device  18 , is disposed on an upper surface of the casing  12 . A display panel  54  as a display unit is mounted on a front wall of the casing  12  above the tray  52 . 
     As shown in  FIG. 2 , a control system of the image forming apparatus  10   a  has a CPU (Central Processing Unit)  60  for controlling the image forming apparatus  10   a . To the CPU  60 , there are connected a heater controller  62  for controlling the heater  48 , a panel controller  64  for controlling the display panel  54 , and motor controllers  68   a  through  68   n  for controlling respective motors  66   a  through  66   n  of the sheet feeding means, the feeder  20 , and the auxiliary scanning feeding means  36 . 
     To the CPU  60 , there are also connected a calendar timer mechanism  70  for automatically controlling the image forming apparatus  10   a  according to the present invention, and a memory  72 . The memory  72  stores settings with respect to turning on and off the image forming apparatus  10   a  by the calendar timer mechanism  70 , as described later. The calendar timer mechanism  70  can gain access to the timer  73  through the CPU  60  for recognizing times and dates, and is associated with a consultation day setting function unit  71  for setting energy saving modes for holidays. 
     The memory  72  includes a nonvolatile storage area for holding preset data even when the power supply thereof is turned off. The memory  72  stores a program such as a control program  72   a  which is read and executed by the CPU  60  for controlling operation of the image forming apparatus  10   a , and data such as calendar data  122 , as described later. 
     A communication controller  74  for communicating with other apparatus through a network  100  is connected to the CPU  60 . 
     As shown in  FIG. 3 , the image forming apparatus  10   a  is connected to the network  100  for communicating with other apparatus that are connected to the network  100 . Specifically, the image forming apparatus  10   a , image forming apparatus  10   b ,  10   c , . . .  10   n , and a server  102  that acts as a management computer are connected to the network  100 , making up an image forming apparatus network system  104  as a whole. Each of the image forming apparatus  10   b ,  10   c , . . .  10   n  is similar to the image forming apparatus  10   a , and has at least the CPU  60 , the calendar timer mechanism  70 , the consultation day setting function unit  71 , the memory  72 , and the communication controller  74 . 
     Operation of the calendar timer mechanism  70  thus constructed will be described below in relation to the image forming apparatus  10   a , which incorporates the calendar timer mechanism  70  therein, and also the image forming apparatus network system  104 . In the operations described below, the calendar timer mechanism  70  operates based on a given program in cooperation with the CPU  60  and the memory  72 . The program is read from an external recording medium, a wide-area communication network, or the like, into a program storage area of the memory  72  by the CPU  60 , and then executed by the CPU  60 . 
     The image forming apparatus  10   b ,  10   c , . . .  10   n  have functions similar to those of the image forming apparatus  10   a  in terms of the calendar timer mechanism  70  and the consultation day setting function unit  71 . The image forming apparatus  10   a  will mainly be described below by way of example. 
     The calendar timer mechanism  70  can set an OFF mode in which all controlled objects (the heater  48 , the display panel  54 , and the motors  66   a  through  66   n ) of the image forming apparatus  10   a  are shut off and operation of the image forming apparatus  10   a  is halted for a relatively long period of time, an ON mode in which all the controlled objects are turned on, i.e., the image forming apparatus  10   a  is in normal operation, and energy saving modes (1) through (6) to be described below. 
     Specifically, as shown in  FIG. 4 , in the energy saving mode (1), the display panel  54  is turned off, and the motors  66   a  through  66   n  and the heater  48  are turned on. In the energy saving mode (2), the display panel  54  and the motors  66   a  through  66   n  are turned off, and the heater  48  is turned on. 
     In the energy saving mode (3), the display panel  54  and the motors  66   a  through  66   n  are turned off, and the heater  48  is turned on at a lowered target temperature, i.e., in a low power consumption state. In the energy saving mode (4), the display panel  54 , the motors  66   a  through  66   n , and the heater  48  are turned off. Therefore, the energy saving mode (4) corresponds to the OFF mode. 
     In the energy saving mode (5), the display panel  54  is turned off, the motors  66   a  through  66   n  are turned on, and the heater  48  is turned on at a lowered target temperature. In energy saving mode (6), the display panel  54  and the heater  48  are turned off, and the motors  66   a  through  66   n  are turned on. 
     The OFF mode may be referred to as a type of energy saving mode, from the viewpoint of reduced power consumption, and the energy saving modes (1), (2), (3), (5) and (6) may be referred to as auxiliary energy saving modes (energy saving sub-modes). The normal ON mode may be referred to as a normal mode. 
     In the present embodiment, the energy saving modes (1) through (3), the OFF mode, and the ON mode are selected, and times at which to shift between these modes are set as desired depending on the demands of the user of the image forming apparatus  10   a .  FIG. 5  shows the relationship between energy saving effects of the energy saving modes (1) through (3) and the OFF mode and rising times. As shown in  FIG. 5 , the energy saving effects of the energy saving modes (1) through (3) and the OFF mode are progressively higher from D to A, and the rising times are progressively shorter from D to A. 
     For example, in the energy saving mode (1), only the display panel  54  is turned off. Though the energy saving effect of the energy saving mode (1) is smaller than the energy saving effects of the other modes, the rising time of the energy saving mode (1) is extremely short because the image forming apparatus  10   a  becomes operational immediately when the display panel  54  is turned on. In the OFF mode, since all the display panel  54 , the motors  66   a  through  66   n , and the heater  48  are turned off, its energy saving effect is greatest. However, it requires the longest rising time for the image forming apparatus  10   a  to become operational because, in particular, the heater  48  requires a long time for heating up. 
     For automatically operating the image forming apparatus  10   a  in a hospital using the energy saving modes (1) through (3) and the OFF mode, a format as shown in  FIG. 6  is generated. The format illustrates mode selections for automatically operating the image forming apparatus  10   a  in a hospital for one week. 
     As shown in  FIG. 6 , the hospital takes Wednesday, Saturday, and Sunday off as nonconsultation days (nonbusiness days) and takes Monday, Tuesday, Thursday, and Friday as consultation days (working days) in each week. The hospital has a longer lunch break for Friday. For each nonconsultation day, the hospital starts its nonconsultation activity at 9 AM. The lunch break extends from noon to 1 o&#39;clock for Monday, Tuesday, and Thursday, for example, and from noon to 2 o&#39;clock for Friday, for example. 
     On Wednesday, Saturday, and Sunday as nonconsultation days, the calendar timer mechanism  70  sets the image forming apparatus  10   a  to the OFF mode so that the energy saving effect is maximum all day long. On the mornings of Thursday and Monday, following nonconsultation days, the OFF mode automatically changes to the ON mode. When the relatively short lunch break begins on Monday, Tuesday, and Thursday, the ON mode shifts to the energy saving mode (1) whose rising time is the quickest, and when the lunch break ends on Monday, Tuesday, and Thursday, the energy saving mode (1) shifts back to the ON mode. When the relatively long lunch break begins on Friday, the ON mode shifts to the energy saving mode (2) whose energy saving effect is higher than the energy saving mode (1). 
     On Monday and Thursday nights, the ON mode shifts to the energy saving mode (3) whose rising time is shorter than the OFF mode and whose energy saving effect is relatively high for the purpose of quickly entering the ON mode the next morning. On Tuesday and Friday nights, which are followed by nonconsultation days, the ON mode shifts to the OFF mode whose energy saving effect is the greatest. 
     In the present embodiment, as described above, the calendar timer mechanism  70  provides the OFF mode for turning off all the controlled modes, the ON mode for turning on all the controlled modes, and two or more energy saving modes, e.g., three energy saving modes (1), (2), and (3), for selectively turning off desired controlled objects or placing them in a low power consumption state. Considering how the image forming apparatus  10   a  operates in the hospital, e.g., in view of the nonconsultation days and lunch breaks, the energy saving modes (1), (2), and (3) are set as desired based on the relationship between energy saving effects and rising times. 
     Specifically, the energy saving effect and the rising time are countervailing factors (see  FIG. 5 ). If the OFF mode with the large energy saving effect is set, then the rising time becomes considerably longer. On Wednesday, Saturday, and Sunday when the preset turn-off time is long, the image forming apparatus  10   a  is set to the OFF mode with the greatest energy saving effect all day long. During lunch breaks with the short turn-off time, the energy saving mode (1) or (2) with the small energy saving effect and the short rising time is selected. 
     Therefore, the calendar timer mechanism  70  can provide more sensitive energy saving countermeasures to achieve a larger energy saving effect as a whole than the conventional calendar timer device which only sets times to turn on and off the power supply. When the image forming apparatus  10   a  is automatically controlled by the calendar timer mechanism  70  according to the present embodiment, the image forming apparatus  10   a  can easily perform an efficient and economical thermal development process. 
     If there is a possibility of operating the image forming apparatus  10   a  at night, then the calendar timer mechanism  70  does not shift from the ON mode directly to the energy saving mode (3) on, for example Monday nights, but during such times can set the energy saving mode (1) and/or the energy saving mode (2). As a result, the image forming apparatus  10   a  can be operated quickly to meet sudden demands. 
     The calendar timer mechanism  70  is capable of displaying the current mode of the image forming apparatus  10   a  on the display panel  54 , for example. It is preferable for the calendar timer mechanism  70  to control LEDs (Light-Emitting Diodes) to be energized continuously or intermittently, or to emit different colors for allowing the user to visually recognize transitions between the modes. 
     When the image forming apparatus  10   a  is placed in the ON mode, it performs a process of forming a visible image on a recording medium F. Specifically, the CPU  60  sends drive signals to the motor controllers  68   a  through  68   n  to energize the motors  66   a  through  66   n . Recording mediums F loaded in the photosensitive medium supply device  14  are taken one at a time from the loader  24  or  26  by suction cups  28  or  30 , and delivered to the image exposure device  16  by the feeder  20 . 
     In the image exposure device  16 , the exposure unit  34  generates a light beam L modulated depending on desired image data, and the light beam L is applied to the recording medium F while being periodically deflected in the main scanning direction. The recording medium F is fed in the auxiliary scanning direction indicated by the arrow X by the feed roller pairs  38 ,  40  of the auxiliary scanning feeding means  36 . The recording medium F is thus two-dimensionally scanned and exposed to the light beam L, for recording a latent image thereon. 
     The recording medium F with the latent image recorded thereon by the image exposure device  16  is then fed to the thermal development device  18  by the feeder  20 . In the thermal development device  18 , the recording medium F is inserted between the heating drum  42 , which has been heated to a predetermined temperature by the heater  48 , and the endless belt  44 . As the recording medium F is gripped and fed along the circumferential surface of the heating drum  42 , the latent image on the recording medium F is thermally developed into a visible image. The recording medium F with the developed visible image thereon is peeled off the heating drum  42  by the peeler blade  46 , and then stacked in the tray  52 . 
     In  FIG. 6 , it is shown that preset modes become effective within preset corresponding time zones. However, an automatic sleep function may be added for automatically changing any energy saving mode, so long as heating-up of the heater  48  will not be obstructed, when it is detected that the image forming apparatus  10   a  has not been operated for a predetermined period of time. In addition, the calendar timer mechanism  70  may be arranged to allow the user to set and distinguish from each other those time zones (e.g., time zones delimited by 15-minute time intervals) in which the automatic sleep function is effective and time zones in which the automatic sleep function is ineffective. 
     The consultation day setting function unit  71 , which is provided as a function of the calendar timer mechanism  70  for additionally setting holidays, consultation days, and nonconsultation days, in addition to the above settings for the days of the week, will be described below with reference to  FIGS. 7 through 11 . 
     The consultation day setting function unit  71  serves to make settings in addition to the energy saving modes set as shown in  FIG. 6 . Items that are set by the consultation day setting function unit  71  are executed in preference to the settings shown in  FIG. 6 . 
     The consultation day setting function unit  71  cooperates with the CPU  60  to make settings based on the images shown in  FIGS. 7 through 10 , which are displayed on the display panel  54 . The server  102  can also display the same images on its display unit, and can set information concerning nonconsultation days, nonconsultation time zones, and regional calendar details. 
       FIG. 7  shows a power saving mode image  110 , which is a main image for making settings with the consultation day setting function unit  71 . When a power saving mode execution button  110   a  on the power saving mode image  110  is selected (clicked) with a given pointing device, the image forming apparatus  10   a  immediately shifts into a set energy saving mode. When a calendar selection button  110   b , a nonconsultation day setting button  110   c , or a nonconsultation time zone setting button  110   d  on the power saving mode image  110  are clicked, the power saving mode image  110  shifts to a calendar selection image  120  (see  FIG. 8 ), a nonconsultation day setting image  130  (see  FIG. 9 ), or a nonconsultation time zone setting image  140  (see  FIG. 10 ), respectively. When a QUIT button  110   e  is clicked, the power saving mode image  110  is closed. 
     As shown in  FIG. 8 , the calendar selection image  120  displays a calendar selection area  120   a  and a summer time setting button  120   b . The calendar selection area  120   a  displays calendar data  122  of respective regions stored in the memory  72 . When one of the calendar data  122  is clicked and selected, it is displayed in a double (dual-line) frame. In the example shown in  FIG. 8 , “JAPAN” is selected. The calendar data  122  selected in the calendar selection area  120   a  serves as an initial value for displaying holidays in the nonconsultation day setting image  130  shown in  FIG. 9 . 
     The calendar data  122  are data having weekday information and holiday information of different countries, stored in respective file formats for those countries. The holiday information of the calendar data  122  is automatically set also with respect to holidays which may fall on certain numbered weekdays within certain months, such as Coming-of-Age Day in Japan (which falls on the second Monday of January). 
     The calendar data  122  can also be set for various regions. For example, “State C” and “State D” may be selected for “Country B”. Since holidays may change even within the same country or region, in this case, calendar data  122  corresponding to a new calendar may be selected. For example, “Country E 2004” which represents calendar data  122  corresponding to a calendar for year 2004 or later may be selected for Country E. The calendar data  122  represented by “Country E 2004” corresponds not only to the single year of 2004, but also the years of 2005 and after, including leap years. The calendar data  122  can additionally read from an external recording medium, a wide-area communication network, or the like. 
     When the summer time setting button  120   b  is clicked, a dialog image  128 , including an area  124  for setting summer time period information and an area  126  for setting offset time information, is displayed in the calendar selection image  120 . In a summer time period that is set in the area  124  of the dialog image  128 , the corresponding energy saving modes are performed with a delay represented by an offset time that is set in the area  126 . As a result, the calendar timer mechanism  70  is compatible with summer (daylight savings) time. 
     If the nonconsultation days of the hospital where the image forming apparatus  10   a  is used are Sundays and other regional holidays only, and do not include half-day holidays, then it is possible to set energy saving modes for the image forming apparatus  10   a  simply by selecting a calendar file for the region where the image forming apparatus  10   a  is used. Stated otherwise, if no detailed energy saving mode settings are required, then the settings made using the nonconsultation day setting image  130  (see  FIG. 9 ) and the nonconsultation time zone setting image  140  (see  FIG. 10 ) may be dispensed with. 
     The nonconsultation day setting image  130  shown in  FIG. 9  is an image for setting nonconsultation days. The nonconsultation day setting image  130  displays day buttons  132   a ,  132   b ,  132   c ,  132   d ,  132   e ,  132   f  and  132   g  corresponding from Sunday to Saturday, date buttons  130   a  for displaying dates of an indicated month in association with the day buttons  132   a  through  132   g , a WORK button  130   b  for setting consultation days, an ALL button  130   c  for setting nonconsultation days, a PM button  130   d  for setting afternoon half-day holidays, and an AM button  130   e  for setting forenoon half-day holidays. 
     The nonconsultation day setting image  130  also displays a month advancing button  130   f  and a month retreating button  130   g , both for designating a month to be set, a month display area  130   h  for displaying a month which is currently being set, an ENTER button  130   i  for entering setting details, and a QUIT button  130   j  for closing the nonconsultation day setting image  130 . 
     In an initial state, the nonconsultation day setting image  130  displays information of a month having days in which operations are to be performed. Each time the month advancing button  130   f  or the month retreating button  130   g  is clicked, the month to be set is advanced or retreated, updating the dates displayed by the date buttons  130   a  and the month displayed by the month display area  130   h.    
     Among the date buttons  130   a , date buttons  130   a  representing dates that have elapsed are displayed with broken lines to indicate that those dates cannot be set. Specifically, the nonconsultation day setting image  130  shown in  FIG. 9  is an example of an image that would be displayed assuming operations are performed therewith on Sep. 11, 2003, wherein dates on and before September 10 are displayed with broken lines. Referring to the calendar data  122 , which is selected using the calendar selection image  120  in an initial state, date buttons  130   a  representing holidays are displayed with cross-hatching, for indicating nonconsultation days. Since the nonconsultation day setting image  130  shown in  FIG. 9  is displayed with reference calendar data  122  based on the Japanese calendar, the dates of September 15 and 23 are displayed with cross-hatching. 
     For changing initial settings, for example, when a consultation day is changed to a nonconsultation day, the ALL button  130   c  is first clicked, and then a date button  130   a  corresponding to the day in question is clicked. The date corresponding to the clicked date button  130   a  is now displayed with cross-hatching, thereby changing the consultation day to a nonconsultation day. Conversely, for changing a nonconsultation day to a consultation day, the WORK button  130   b  is first clicked, and then a date button  130   a  corresponding to the day in question is clicked. The date corresponding to the clicked date button  130   a  is now displayed as blank, thereby changing the nonconsultation day to a consultation day. 
     Similarly, for changing a nonconsultation day or a consultation day to an afternoon half-day holiday or to a forenoon half-day holiday, the PM button  130   d  or the AM button  130   e  is clicked, and then a date button  130   a  corresponding to the day in question is clicked. The date at the clicked date button  130   a  is now displayed with cross-hatching, indicating an afternoon half-day holiday, or is displayed with broken-line cross-hatching, indicating a forenoon half-day holiday. 
     After clicking the WORK button  130   b , the ALL button  130   c , the PM button  130   d  or the AM button  130   e , if one of the day buttons  132   a  through  132   g  is clicked, all settings of the days corresponding to the clicked day button are changed. In the example of the date buttons  130   a  shown in  FIG. 9 , when the day button  132   g  is clicked after the PM button  130   d  has been clicked, all the Saturdays are set to afternoon half-day holidays. If the Wednesdays are nonconsultation days as shown in  FIG. 6 , then the day button  132   d  may be clicked after the ALL button  132   c  has been clicked. When the day button  132   d  is thus clicked, all the Wednesdays are set to nonconsultation days, and regardless of the Wednesday settings shown in  FIG. 6 , the image forming apparatus  10   a  on Wednesday is forcibly set to an energy saving mode or the OFF mode with respect to the month to be set. 
     On the nonconsultation day setting image  130 , day settings are made with respect to a given month to be set. However, day settings may be made with respect to all months by performing certain control actions. 
     Days that have elapsed, consultation days, nonconsultation days, afternoon half-day holidays, and forenoon half-day holidays may be displayed in different colors on the date buttons  130   a  for better visual recognition. 
     As shown in  FIG. 10 , the nonconsultation time zone setting image  140  displays an all-day nonconsultation setting area  140   a  for setting a nonconsultation time zone on a nonconsultation day, an afternoon nonconsultation setting area  140   b  for setting an afternoon nonconsultation time zone on an afternoon half-day holiday, and a forenoon nonconsultation setting area  140   c  for setting a forenoon nonconsultation time zone on a forenoon half-day holiday. The nonconsultation time zone setting image  140  also displays a nonconsultation day mode setting area  140   d , an afternoon half-day holiday mode setting area  140   e , and a forenoon half-day holiday mode setting area  140   f  for setting energy saving modes on nonconsultation days, afternoon half-day holidays, and forenoon half-day holidays, respectively. Furthermore, the nonconsultation time zone setting image  140  displays an UP button  140   g  and a DOWN button  140   h  for setting various numerical values on the nonconsultation time zone setting image  140 , a server information check box  140   i  for using information of the server  102  (see  FIG. 3 ), an ENTER button  140   j  for entering settings, and a QUIT button  140   k  for closing the nonconsultation time zone setting image  140 . 
     Each of the all-day nonconsultation setting area  140   a , the afternoon nonconsultation setting area  140   b , and the forenoon nonconsultation setting area  140   c  has a time zone start setting area  142   a  and a time zone end setting area  142   b  each for setting times. Specifically, after an hour entering window  144   a  or  a  minute entering window  144   b  of the time zone start setting area  142   a  and the time zone end setting area  142   b  are clicked, the UP button  140   g  or the DOWN button  140   h  may be clicked to increment or decrement an hour or minute setting. The UP button  140   g  or the DOWN button  140   h  may change the minute setting in the minute entering window  144   b  at intervals of 15 minutes, for example. 
     In the all-day nonconsultation setting area  140   a  and the forenoon nonconsultation setting area  140   c , the time zone start setting areas  142   a  can set times for the forenoon of the current day and times for the afternoon of the preceding day. In the all-day nonconsultation setting area  140   a  and the afternoon nonconsultation setting area  140   b , the time zone end setting areas  142   b  can set times for the afternoon of the current day and times for the forenoon of the following day. Since times can thus be set from time zones in the afternoon of the preceding day to time zones in the forenoon of the following day, the image forming apparatus  10   a  can continuously be set to an energy saving mode up to 7 AM, for example, for a consultation day which follows a nonconsultation day that has been set on the nonconsultation day setting image  130 . Stated otherwise, nonconsultation time zones, afternoon nonconsultation time zones, and forenoon nonconsultation time zones can be extended in preference to the settings on the following day and the preceding day on the nonconsultation day setting image  130 . 
     After the nonconsultation day mode setting area  140   d , the afternoon half-day holiday mode setting area  140   e , or the forenoon half-day holiday mode setting area  140   f  has been clicked, the UP button  140   g  or the DOWN button  140   h  is clicked a suitable number of times to set one of the energy saving modes (2) through (6) on a nonconsultation day, an afternoon half-day holiday, or a forenoon half-day holiday in the nonconsultation day mode setting area  140   d , the afternoon half-day holiday mode setting area  140   e , or the forenoon half-day holiday mode setting area  140   f . Numerical values displayed in the nonconsultation day mode setting area  140   d , the afternoon half-day holiday mode setting area  140   e , and the forenoon half-day holiday mode setting area  140   f  correspond to the numerical values of the energy saving modes shown in  FIG. 4 . The mode represented by (1) is the ON mode and is excluded. When the numerical value (4) representing the OFF mode is set in the nonconsultation day mode setting area  140   d , the afternoon half-day holiday mode setting area  140   e , and the forenoon half-day holiday mode setting area  140   f , the nonconsultation time zone, the afternoon nonconsultation time zone, and the forenoon consultation time zone are forcibly set to the OFF mode regardless of the settings shown in  FIG. 6 . On a day that is set as a consultation day on the nonconsultation day setting image  130  shown in  FIG. 9 , the settings shown in  FIG. 6  are effective in a time zone that is not affected by an extension of the nonconsultation time zone, the afternoon nonconsultation time zone, or the forenoon nonconsultation time zone, on the preceding day or the following day of the settings in the nonconsultation time zone setting image  140 . 
     A check mark in the server information check box  140   i  switches between a displayed state and a non-displayed state each time the server information check box  140   i  is checked. When the check mark is displayed in the server information check box  140   i , information from the server  102  (see  FIG. 3 ) can be used. When the check mark is displayed in the server information check box  140   i , the information set by the server  102  is used in preference to the data set by the image forming apparatus  10   a , making it possible to share the information from the server  102 . This process is performed by the consultation day setting function unit  71 , in cooperation with the CPU  60  and the memory  72 , based on the control program  72   a.    
     A processing sequence based on the control program  72   a  will be described in detail below with reference to  FIG. 11 . The control program  72   a  is read from an external recording medium, a wide-area communication network, or the like, into the program storage area of the memory  72  by the CPU  60 , and executed by the CPU  60 . 
     In step S 1 , the image forming apparatus  10   a  determines whether it uses information in the internal memory  72  thereof or not. Specifically, if no check mark is displayed on the nonconsultation time zone setting image  140 , then it is judged that the image forming apparatus  10   a  uses the information from its own memory  72 , and control goes to step S 2 . If the check mark is displayed in the nonconsultation time zone setting image  140 , then it is judged that the image forming apparatus  10   a  uses information from the server  102 , and control goes to step S 3 . 
     In step S 2 , the information currently set at that time within the various images is read. Alternatively, if there is information that has been previously set saved in the memory  72 , then that information is read from the memory  72 . 
     In step S 3 , the image forming apparatus  10   a  accesses the server  102  and requests the server  102  to supply information. The server  102 , having received the request, supplies the information saved in its own memory through the network  100  to the image forming apparatus  10   a.    
     In step S 4 , the image forming apparatus  10   a  receives the data supplied from the server  102 . If reception of the data is successful, then control goes to step S 5 . If reception of the data fails, control goes to step S 6 . The branching process in step S 4  is performed to increase the reliability of the image forming apparatus  10   a . Normally, the image forming apparatus  10   a  does not fail to receive data from the server  102 . 
     In step S 5 , the CPU  60  stores the information received from the server  102  into a certain storage area of the memory  72  and uses the stored information. At this time, the CPU  60  does not write the information from the server  102  over the information already held by the image forming apparatus  10   a.    
     In step S 6 , the CPU  60  displays any information reception failures on the display panel  54 , while also storing initial settings into a certain storage area of the memory  72  and uses the stored initial settings. The initial settings represent data that are set to the extent that they cause no trouble in the operation of the image forming apparatus  10   a.    
     On the nonconsultation time zone setting image  140  displayed by the server  102 , the server information check box  140   i  is not displayed, but a forced information distribution check box (not shown) is displayed. When the forced information distribution check box is checked to display a check mark thereon, the information of the server  102  is forcibly distributed to the image forming apparatus  10   a  through  10   n  and can be forced to be used thereby, irrespective of whether the check marks are displayed in the server information check boxes  140   i  of the image forming apparatus  10   a  through  10   n  or not. 
     As for processes by which information from the server  102  may be shared with the image forming apparatus  10   a , etc., apart from temporarily transmitting and supplying the information from the server  102  to the image forming apparatus  10   a , processes may be used by which the information is supplied successively as needed, or by which the memory  72  itself may appear to be commonly shared. The functions of the server  102  may also be provided by one any one of the image forming apparatus  10   a  through  10   n.    
     While operation of the image forming apparatus  10   a  has mainly been described above, the other image forming apparatus  10   b  through  10   n  operate in the same manner as the image forming apparatus  10   a.    
     As described above, the calendar timer mechanism  70  according to the present embodiment can make additional settings with respect to the energy saving modes shown in  FIG. 6 , by operating the consultation day setting function unit  71 , making it possible to set times flexibly and in detail. 
     For example, by setting consultation days and nonconsultation days on each day or weekday, based on calendar data  122  including weekday information and holiday information, the image forming apparatus  10   a  through  10   n  can be set to energy saving modes within desired nonconsultation day time zones on nonconsultation days and on Sundays and holidays which are not consultation days. Thus, the amount of energy consumed by the image forming apparatus  10   a  through  10   n  can easily be reduced. 
     Regional and yearly calendars can be applied to allow the image forming apparatus  10   a  to set energy saving modes to match different holidays in various regions of the world through simple control actions. 
     If the image forming apparatus  10   a  through  10   n  are expected to have the same settings with respect to energy saving modes, then the server  102  alone may be used to set information as to energy saving modes, and the check mark will be displayed on the server information check box  140   i  of the image forming apparatus  10   a  through  10   n . In this manner, the time required to set energy saving modes in the image forming apparatus  10   a  through  10   n  is greatly reduced. 
     In the present embodiment, the calendar timer mechanism  70  and the consultation day setting function unit  71  are incorporated in the image forming apparatus  10   a  through  10   n . However, the calendar timer mechanism  70  and the consultation day setting function unit  71  are not limited to use in the image forming apparatus  10   a  through  10   n , but may be incorporated in various processing apparatus such as a medical image processing system, a medical print system, etc. 
     Although a certain preferred embodiment of the present invention has been shown and described in detail, it should be understood that various changes and modifications may be made therein without departing from the scope of the appended claims.
