Title: Message data reception device and method for controlling display of message data items and other data items related to the message

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a data processing device, data display system, data display method, and storage medium, and more particularly to a data processing device and data display system with a data communication function and a data display method for the data processing device and data display system. 
     Recently, a portable data processing device with the data communication function has been popularized, which is represented by a paging receiver with the electronic notebook function. 
     The data processing device with a function like this has a lot of keys and a large display screen while giving importance to portability, and has a wide variety of functions, such as the various types of functions as an electronic notebook (telephone directory, schedule, memo, and the like), a message creation function to create a long message including Chinese characters (Kanji) and the like, and the data communication function by a wired/wireless modem and by means of infrared rays or DTMF signal output. 
     In this type of data processing device, the display screen is larger when compared with a conventional pager, and therefore, a long message can fully be displayed at one time. 
     There is another portable data processing device, which has a function to shift the display to a display of the personal data associated with the sender who has sent the message or the data associated with the matters included in the message data, by performing a necessary key operation from the message display screen of the received electronic mail, in the case where the data communication function is applied to the communication of the electronic mail. 
     However, the shift from the display of the above mentioned received message to the display screen of another data associated with the received message, includes a shift to a mode associated with the other data. 
     Accordingly, for each shift of the display, the CPU must start up an application program corresponding to the other data. 
     Recently, in order to achieve the speed up of a processing like this, such a method that the application program is temporarily made to be resident in the memory so as to reduce the time required for the start up, has also been adopted, but when the displays of a plurality of associated data are shifted, a plurality of corresponding application software must be resident, and the load for the processing of the CPU is extremely large. 
     Therefore, even if a plurality of operative application software are provided, such a display shifting function as mentioned above could not always achieve a comfortable operation, depending on the performance of the CPU, the display performance in which the importance is given to the portability, and besides, the operational environment.

     DETAILED DESCRIPTION OF THE INVENTION 
     A preferred embodiment of a data processing device, data display system, and data display method according to the present invention will now be described with reference to the accompanying drawings. 
     First Embodiment 
     The first embodiment in the case where the present invention is applied to a paging receiver which has the function of an electronic notebook and conforms to communication standard RCRSTD-43, will be described below by referring to drawings. 
     FIG. 1 shows the circuit arrangement of the first embodiment. A paging receiver  1  comprises an antenna  11 , a receiver  12 , a decoder  13 , an ID-ROM  14 , a RAM  15 , a ROM  16 , a CPU  17 , a display driver  18 , a display  19 , an alarm driver  20 , a key input  21 , a speaker  22 , an LED  23 , a vibrator  24 , and an IF (interface)  25 . The decoder  13 , ID-ROM  14 , RAM  15 , ROM  16 , CPU  17 , display driver  18 , alarm driver  20 , key input  21 , and IF  25  are connected by a bus line B. The display  19  comprises, for example, a liquid crystal display panel which is driven by the display driver  18 . The speaker  22 , LED  23 , and vibrator  24  are driven by the alarm driver  20  to perform alarming. 
     The antenna  11  receives data (frame data) sent from a wireless base station (not shown), and outputs the data to the receiver  12 . The receiver  12  is connected to the decoder  13 , and is driven on the basis of a control signal from the decoder  13  to demodulate and detect the received data. The receiver  12  respectively outputs the data in the case of being received binary level modulation data and four-level modulation data by taking in a synchronous portion in the data. 
     The decoder  13  includes a de-interleaving circuit  131 , a buffer memory  132 , an error correcting circuit  133 , and an address data collating circuit  134 . 
     The binary level modulated or four-level modulated digital data input from the receiver  12  is rearranged into parallel data of 8 bits, and is output to the bus line B. 
     The address data received by the address data collating circuit  134  and the address data previously registered in the ID-ROM  14  are collated. When the coincidence is detected, the address data collating circuit  134  issues a command to the receiver  12  so that the receiving operation may be continued. 
     The de-interleaving circuit  131  in the decoder  13  rearranges or de-interleaves the parallel data obtained by the receiver based on the modulation mode and a transmission speed of the received signal, and obtains the one frame data. The obtained data is temporarily stored in the buffer memory  132 . A BCH code of the one frame data is further decoded to perform an error correction. Message data including a sender code (numerical data of the lower 4 digits of the telephone number of the sender) is extracted. 
     The ID-ROM  14  stores a frame No. to be received by the paging receiver  1 , address data (code word) of  32  bits, vector type data of 3 bits, contents of various settings, contents of display control, call number, and the like in a correlated manner. 
     As shown in FIG. 2, the RAM  15  comprises plural memory areas, i.e., a received message area RM for storing the received message, a telephone number directory area TL for storing a plurality of personal data including telephone numbers and names, a schedule data area SC for storing schedule data, and a memo data area MM for storing memo data as the function of an electronic notebook, and empty area. The RAM  15  is formed of an EEPROM and the contents thereof are kept to be stored regardless of the feeding state of the electric power depending on an operation of a power supply key provided in the key input  21 , or the like. 
     The received message area RM, whose stored contents are shown in FIG. 3, is an area which stores a plurality of received message data each comprising a storing address, a reception address, received message contents, a sender code flag, a sender code (lower four digits of telephone number), and a reception day and time. 
     The sender code flag is set to “1” in the case where numerical data of 4 digits expressing the sender is additionally set at the end of the received message data together with the specified mark, for example, “] ]” and the name corresponding to the numerical data is registered in the telephone number directory area TL. When the sender code flag is set to “1,” the additionally set numerical data of 4 digits is set to the sender code. 
     The telephone number directory area TL, whose stored contents are shown in FIG. 4, is an area which stores a plurality of personal data each comprising a storing address, a telephone number, a name, and private data. A character string comprising kana(Japanese Character)/kanji, alphanumeric characters, and the like is stored in the telephone number directory area TL as character data according to the data input from the key board  211  of the key input  21  or the data input from the IF  25 . The private data is arranged to set, for example, an address, a birthday, an office, and the like by an arbitrary character string. 
     The schedule data area SC, whose stored contents are shown in FIG. 5, is an area which stores a plurality of schedule data each comprising a storing address, day and time, schedule contents, and an alarm setting flag showing whether an alarm operation should be performed or not. The data input from the key board  211  of the key input  21  or the schedule data input from the IF  25  is stored in the schedule data area SC. 
     The memo data area MM, whose stored contents are shown in FIG. 6, is an area which stores a plurality of memo data each comprising a storing address, a title, and memo contents. The memo data input from the key board  211  of the key input  21  or the memo data input from the IF  25  is stored in the memo data area MM. 
     The ROM  16  stores various types of programs and various types of data for operating the CPU  17 , and comprises an EEPROM. 
     To be more specific, these respective programs and various types of data include a shift control program for an operation mode (telephone number directory mode, schedule mode, and memo mode) on the basis of the data input from the key board  211  of the key input  21 , an application program, a viewer (one of application programs, which is loaded only for the display of the data registered in each mode. When the viewer is operated, input/editing is impossible, and at the time of start up of the data processing device, the viewer is loaded by giving comparatively a little load to the working memory), and a character generator  161  which displays kana-kanji, alphanumeric characters, and the like, or stores them in the areas for the electronic notebook function of the RAM  15  on the basis of the data input from the key board  211  provided in the key input  21 . 
     The CPU  17  contains a clock  171 , a counter  172 , a timer  173 , a register  174 , a working memory  175 , and an application loader  176 , and controls the total operation of the paging receiver  1  according to the control program stored in the ROM  16 , and further, controls the storage and display operation of the data, to be described later. 
     The clock  171  always counts the present time, and detects the reception day and time of the message data, the registration time of other modes, the start/end time of the schedule data, and the like, which are respectively stored in the correlated manner. 
     Furthermore, as shown in FIG. 7, the register  174  stores a plurality of sets of data, wherein one set of data is made of the name of the sender corresponding to the sender code detected from the received message and the count value of the associated message data, and further stores the number of times of key operations by the display shift key to be described later and the read out address as a set. 
     Furthermore, the application loader  176  has a function to load, in the case where the mode shift instruction is detected from the key input  21 , the corresponding application software and viewer from the ROM  16  to the working memory  175  of the CPU  17 . 
     The display driver  18  drives the display  19  to display the received message and other data. 
     The alarm driver  20  drives the speaker  22  which informs of receiving the message by sound, the LED  23  which informs of receiving the message by lighting or flashing, and the vibrator  24  which informs of receiving the message by vibration, under the control of the CPU  14 . 
     The key input  21  has the key board  211  which comprises various types of character input keys for inputting kana-kanji and alphanumeric characters, as well as a power supply key, a mode shift key, a reset key, and a display shift key for changing the display screen. 
     The IF  25  is a circuit which sends and receives the data to and from the external electronic equipment by using the data cable, the infrared rays, and the like as the transmitting medium, on the basis of the control from the CPU  17 , and has a buffer for temporarily storing the transmitting data and the received data. 
     Next, the operation of the embodiment will be described. 
     FIG.  8  and FIG. 9 show the contents of such a series of processing by the CPU  17  in which message data to the own equipment is received, the received data is stored and finally is displayed and reported if needs arise. At first, data of one frame conforming to the frame No. and address data stored in the ID-ROM  14  is taken into the decoder  13  in the state of intermittent receiving in synchronization with the received radio waves (step S 01 ). 
     The data taken in the decoder  13  is demodulated and subjected to the data processing (temporary storing in the buffer memory  132 , rearrangement of the received data by the de-interleaving circuit  131 , error correcting processing of the received data by the error correcting circuit  133 , and coincident determination of the address data by the address data collating circuit  134 ), and the message data in the message field of the received data is stored in the received message area RM of the RAM  15 . 
     In the case where the above mentioned specified mark “] ]” and the numerical data of 4 digits showing the sender are added at the end of the message data, “1” is set to the corresponding sender code flag of the received message area RM, and after setting the numerical data of 4 digits as the sender code, personal data conforming in lower 4 digits of the telephone number is retrieved from the telephone number directory area TL of the RAM  15  by using that numerical code of 4 digits (step S 02 ), and it is determined whether the personal data of the corresponding sender exists or not (step S 03 ). 
     FIG. 10 shows the state where new received message data is stored in the received message area RM, and here, the state is shown, where in the storing address “0400,” a message data whose received message contents are “I drafted meeting report” is stored as received message data together with the reception day and time “97.11.15 17:00” obtained by the clock  171  in the CPU  17 . 
     The sender code flag in the received message data is set to “1” and the numerical-data of 4 digits “4321” is set at the sender code, and therefore, it is understood that the sender code is additionally set following the message contents of “I drafted meeting report” in the received message. 
     Then, by retrieving the lower 4 digits of the telephone number of the personal data stored in the telephone number directory area TL using the sender code, it is understood that as shown in FIG. 4, the personal data of the sender, that is, a storing address “1100,” a telephone number “098-765-4321,” a name “Taro NOMURA,” and private data “private data 2 (contents are not specifically described),” is stored. 
     If it is determined at step S 03  that the personal data of the corresponding sender exists, the data associated with the sender is retrieved from all file data of the RAM  15  shown in FIG. 3 to FIG. 6, by using the sender code “4321,” and the names “NOMURA” and “Taro NOMURA” as the key words (step S 04 ), and the storing address of the data which conforms as the result of the retrieving, is stored in the register  174  in the CPU  17  as a read-out address. In the meantime, the number of items of data is counted by the counter  172  in the CPU  17  so that the number of items of windows to be displayed is determined, and it is stored in the register  174 . Furthermore, because of detecting that there is data which conforms as the result of the retrieving, the application loader  176  reads out the viewer from the ROM  16 , and loads it in the working memory  175  (step S 05 ). 
     FIG. 11 shows the storing state of the register  174  in the CPU  17  at this moment. The detected sender code “14321” and sender name “Taro NOMURA” are stored together with the count value “4” of the associated data, and the storing address “0400” of the lately received message data stored in the received message area RM as the readout address, and each of the storing addresses “0100,” “1100,” “2300,” “8100” of the associated data obtained by the retrieving are stored. 
     In this case, by summing up the received message data and the count value “4” of the associated data obtained by the retrieving, the number of items of data, that is, the number of items of windows to be displayed becomes “5,” and therefore, the numbers of times of key operations of the display shift key of the key input  21  corresponding to the respective readout addresses are respectively remainder numbers of “5” of “5N (N is a natural number),” “5N+1,” 5N+2,” “5N+3,” “5N+4”. 
     After that, while starting the clocking of the specified time of the receiving informing by the timer  173  in the CPU  17  (step S 06 ), at least one of the speaker  22 , LED  23 , and vibrator  24  which are previously set is driven by the alarm driver  20  so as to inform of the reception of the message. At the same time, the displays in which the head end is the window of the received message data are performed in the display  19  by the display driver  18  (step S 07 ). 
     FIG. 12 shows the display screen of the display  19  at this moment, and expresses such an image that the message contents “I drafted meeting report,” the sender “Taro NOMURA,” and the reception day and time “97.11.15 17:00” are indicated as the received message data, on the card (window display type) having the heading of “1” and positioned at the head end, among 5 cards having headings of “1” to “5” displayed on label display section  191 . 
     In this case, the shown received message data is read out of the received message area RM of the RAM  15 , on the basis of the read out address “0400” corresponding to the number “5N” of times of key operations stored in the register  174 . 
     After this display, by repeatedly determining whether any one of the keys in the key input  21  has been operated or not (step S 08 ), or whether or not the timer  173  in the CPU  17  has finished the clocking of the specified time to perform the receiving report (step S 11 ), the operation of the display shift key and the time up of the timer  173  are waited for. 
     Then, in the case where it is determined in step S 08  that any one of keys of the key input  21  has been operated, it means that a key operation has been performed within the specified time to perform the receiving report, and therefore, after resetting the clocking operation by the timer  173  (step S 09 ), the report caused by driving at least one of the speaker  22 , LED  23 , and vibrator  24  with the alarm driver  20 , is stopped, and at the same time, only in the case where the operated key is the display shift key, the read out address corresponding to the number of times of operations of that display shift key is obtained from the register  174 , and the viewer reads out the data stored in the corresponding storing address, from any one of the received message area RM, telephone number directory area TL, schedule data area SC, and memo data area MM, and displays the data by shifting the state from the display state of the received message data at step S 07  (step S 10 ), and the processing is finished. 
     FIG. 13 shows a display screen in the case where the display shift key of the key input  21  is continuously operated two times from the state of the display screen shown in FIG.  12 . In this case, an image is shown, in which the telephone number “098-765-4321,” the name “Taro NOMURA,” and the private data “private data 2” are indicated as the personal data read out from the telephone number directory area TL, on the card having the heading of “3” among 5 cards having headings of “1” to “5” displayed on the label display section  191 . 
     The personal data displayed here is read out on the basis of the read out address “1100” corresponding to the number “5N+2” of times of key operations stored in the register  174 . 
     Furthermore, in the case where it is determined at step S 11  that the timer  173  in the CPU  17  has finished the clocking of the specified time to perform the receiving report, it means that the specified time to perform the receiving report has elapsed while any key operation of the key input  21  is not performed, and therefore, the report made by driving at least one of the speaker  22 , LED  23 , and vibrator  24  with the alarm driver  20 , is stopped. At the same time, the display of the received message data in the display  19  as shown in FIG. 12 up to that time, is stopped (step S 12 ), and the processing is finished. 
     Furthermore, in the case where it is determined at step S 03  that there is no personal data of the corresponding sender, it means that there is no personal data in which the lower 4 digits of the telephone number conforms to the numerical code of 4 digits added and set to the received message data from the telephone number directory area TL of the RAM  15 , or that primarily, the numerical code of 4 digits is not added and set to the received message data. In any case, the sender cannot be specified from the personal data stored in the telephone number directory area TL. Therefore, the clocking of the specified time of the receiving report by the timer  173  in the CPU  17  is started (step S 13 ), and in the mean time, the presence of the receiving of a message is reported by driving at least one of the speaker  22 , LED  23 , and vibrator  24  which is previously set by the alarm driver  20 , and at the same time, the display of the received message data is performed in the display  19  by the display driver  18  (step S 14 ). 
     At this moment, it is only the character portion of 3 lines made by eliminating the image corresponding to 5 cards having the headings of “1” to “5,” on the label display section  191  from the display contents shown in FIG. 12 that is shown in the display  19 . 
     After the display of the received message data, by repeatedly determining whether or not any key of the key input  21  has been operated (step S 15 ), or whether or not the timer  173  in the CPU  17  has ended the clocking of the specified time to perform the receiving report (step S 18 ), a key operation and the time up of the timer  173  are waited for. 
     Then, in the case where it is determined at step S 15  that a key is operated, it means that a key operation has been performed within the specified time to perform the receiving report, and therefore, after resetting the clocking operation by the timer  173  (step S 16 ), the report made by driving at least one of the speaker  22 , LED  23 , and vibrator  24  with the alarm driver  20 , is stopped, and at the same time, while keeping the display state of the received message data in step S 14  (step S 17 ), this processing is finished. 
     Furthermore, in the case where it is determined at step S 18  that the timer  173  in the CPU  17  has ended the clocking of the specified time to perform the receiving report, it means that the specified time to perform the receiving report has elapsed without performing any key operation of the key input  21 . Therefore, the report made by driving at least one of the speaker  22 , LED  23 , and vibrator  24  with the alarm.driver  20 , is stopped, and at the same time, the display of the received message data in the display  19  up to that time, is stopped (step S 19 ), and this processing is finished. 
     Other embodiments of the data processing device according to the present invention will be described. The same portions as those of the first embodiment will be indicated in the same reference numerals and their detailed description will be omitted. 
     Second Embodiment 
     In the first embodiment, data to be displayed in the window of other mode can be seen by starting up the viewer program. However, it is impossible to input/edit the window data under the execution of the viewer. It is necessary to stop the viewer and to shift to the other mode to input/edit the window data. In the second embodiment, it is possible to start up the corresponding application program and to directly shift to each mode from the read out mode of the received message data by touching the label display section  191 . 
     The second embodiment in the case where the present invention is applied to a paging receiver which has the function of an electronic notebook and conforms to the standard RCRSTD-43, will be described below by referring to drawings. 
     FIG. 14 shows the circuit arrangement thereof, which is basically similar to that shown in FIG. 1, and therefore, the same numeral is applied to the same part, and the description thereof will be omitted. 
     The key input  21  comprises a touch panel provided as one piece on the display  19  and a driving circuit thereof, and with the touching operation using fingers, a specialized stylus pen  212 , or the like, it can perform the input of the desired characters, numerals, symbols, and the like, and setting, execution, selective specification, and the like of various types of functions, by the positional specification corresponding to the positions of the key board  211  and the like shown in the display  19 , the writing operation, and the like. 
     A transmission buffer  26  has a function to change the data into a data corresponding to the communication network of sending and to hold that, in the case where the transmission instruction of the data newly created and registered in each mode (especially, in the memo mode), is detected from the key input  21 . 
     A transmitter  27  is a circuit to transmit and output the data stored in the transmission buffer  26 , and an example is a modem (including both wired and wireless types), a dialer, or an infrared ray output section. 
     A storage medium driver  28  is a device for reading out the data stored in a portable storage medium  29  (including a semiconductor memory, a magnetic disk, an optical disk, an optical magnetic disk, or the like), or for writing the data into the portable storage medium  29 . 
     The RAM  15  comprises, for example, an EEPROM, and as shown in FIG. 15, includes a working area WHA used during the normal data processing, a data management area DM to be described later, a received message area RM for storing the received message data, a telephone number directory area TL for storing a plurality of personal data including telephone numbers, a schedule data area SC for storing the schedule data, and a memo data area MM for storing the memo data. The address range of each area is shown in the figure, and the contents thereof is kept to be stored regardless of the feeding state of the power supply or the like. 
     The data management area DM stores the correlation between the message data and each mode data, even if the processing at the time of receiving the message has been finished. As shown in FIG. 16, the data management area DM comprises 4 areas DMA, DMB, DMC, and DMD, and further it stores the display information (an icon picture of the label display section  191 ) and the like during the window display. 
     The area DMA stores the icon picture displayed in the label display section  191  of each window together with the management area, during the window display of the data, and at the time of the display of the received message, the viewer reads out and displays the data of the corresponding window by specifying, with a touch, the icon displayed in the label display section  191  of each window. 
     Furthermore, in the case where the icon displayed in the label display section  191  is specified with a touch continuously two times, the application loader  176  reads out the corresponding application program from the application program memory  162  of the ROM  16  in addition to the viewer  163 , and loads it to the working memory  175 , and while keeping the window display (that is, while making it possible to refer to the associated data of other modes, because of the loading in advance of the viewer), the shift from the display of the received message to the execution state of each mode to perform referring/input/editing/ deletion of the data, is performed. 
     The area DMB stores the data which is made to be the retrieving object when the message data is received, and in the first embodiment, merely the retrieving with the numeral of 4 digits (sender code) by displaying the name of the sender, is performed, but in the second embodiment, the retrieving by the reception day and time data, or the data of the key word with a specified character string is also possible, and the data for the retrieving can properly be input and set, and a flag F 1  for controlling the execution/nonexecution of retrieving is stored for that. 
     The area DMC is an area which stores, in the correlated state, the data detected as the result of the retrieving by using the area DMB when receiving the message data (however, this area is used only in the case of displaying the name of the sender), the related key word common to each mode data, the number of associated data showing the number of windows of the window display of the received message, and the corresponding address LA which defines the link of the data with the associated data storing address to be described later. 
     The area DMD is an area which stores the storing address of the associated data of each mode linked with the corresponding address LA of the area DMC, and in the meantime, which stores a display flag F 2  defining the execution/nonexecution of the window display of the data during the window display in the state of being correlated to each data. 
     The received message area RM, whose stored contents are shown in FIG. 17, is an area which stores a plurality of received message data each comprising a storing address, a reception address, received message contents, a reception day and time, a flag F 30 , and a flag F 31 . 
     The flag F 30  is used for the control of determining whether or not the registration of the window display as the associated data should be performed, and “1” shows allowance of the window display and “0” shows inhibition of the window display, and it is linked to the flag F 2  in order to perform the setting/control associated with the window display at the time of received message display, in each mode. 
     The flag F 31  is provided as a flag forced to be set as the associated data which should be displayed in the case of the unconfirmed message, and “1” shows the unconfirmed message and “0” shows the confirmed message, and when the display of the total message is detected, “0” is set. 
     Accordingly, in the unconfirmed message, “1” is respectively set to the flag F 30  and to the unconfirmation flag F 31 . 
     The telephone number directory area TL, whose stored contents are shown in FIG. 18, is an area which stores a plurality of personal data each comprising a storing address, a telephone number, a name, private data, and a flag F 4 . The private data sets, for example, the address, the birthday, the office, or the like by using an arbitrary character string, by detecting the input operation from the key board  211  of the key input  21 , or the selective operation by the stylus pen  212 . 
     The flag F 4  is a flag to be used for the control of determining whether or not the window display of the associated data should be performed, similar to the flag F 30  of the received message area RM. 
     The schedule data area SC, whose stored contents are shown in FIG. 19, is an area which stores a plurality of schedule data each comprising a storing address, a day and time, schedule contents, an alarm setting flag showing whether or not the alarm report should be performed, and a flag F 5 . 
     The flag F 5  performs the same function as those of the flag F 2  of the area DMD of the data management area DM, the flag F 30  of the received message area RM, and the flag F 4  of the telephone number directory area TL. 
     The memo data area MM, whose stored contents are shown in FIG. 20, is an area which stores a plurality of memo data each comprising a storing address, a title number, memo contents, and a flag F 6 . 
     The flag F 6  also performs the same function as those of the flags F 2 , F 30 , F 4 , and F 5 . 
     In the ROM  16 , the application program memory  162  in which the application program used in each mode is stored on the table, and the viewer  163  which starts up when the display of the associated data is instructed in the read out mode of the received message data are stored, as well as the character generator  161  described in the first embodiment. 
     This shows, in the visually discriminated state, the application program and viewer which are stored in the state of being mixed with the control program stored in the ROM  16  in the first embodiment. 
     Next, the operation of the second embodiment will be described. 
     FIG. 21 to FIG. 25 show the processing contents from the state of waiting for the receiving of the message and the selective operation of the mode. At the beginning, by repeatedly determining whether a selective operation of a mode by the key input  21  is detected (step S 101 ), or a receiving of the message data to the own equipment is detected (step S 102 ), the detection is waited for. 
     Then, when it is determined at step S 102  that receiving of the message has been detected, the received frame data is taken in (step S 103 ). In the decoder  13 , it is demodulated and subjected to data processing (temporary storage in the buffer memory  132 , rearrangement of the received data by the de-interleaving circuit  131 , error correcting processing of the received data by the error correcting circuit  133 , and address data correspondence determination by the address data collating circuit  134 ), and the message data in the message field of the received data is stored in the received message area RM of the RAM  15  (step S 104 ). 
     After that, the message data in the stored frame data is analyzed (step S 105 ). 
     FIG. 26 shows the state where the new received message data is stored in the received message area RM, and here, a state is shown, where the message data having the received message contents of “I drafted meeting report” is stored in the storing address “4200”as the received message data, together with the reception day and time “97.11.15 17:00” obtained by the clock  171  in the CPU  17 . It is assumed that the message of the storing address “3900” is not confirmed and “1” is set to the corresponding unconfirmation flag F 31 . 
     On the basis of the analyzed results of the received message data, as for the received message data, retrieving is performed by using such retrieving contents that “1” is set to the flag F 1  at the area DMA in the data management area DM (step S 106 ). 
     In the case it is determined that the retrieving contents are the numeral of 4 digits as shown in FIG. 16 (step S 107 ), retrieving is performed in the telephone number directory area TL by using that numeral of 4 digits, and it is determined whether or not there are any coincident lower 4 digits of the telephone number (step S 109 ). 
     In the case where there are no coincident lower 4 digits, the clocking of the specified time of the receiving report by the timer  173  in the CPU  17  is started (step S 110 ). The receiving of a message is reported by driving at least one of the speaker  22 , LED  23 , and vibrator  24  which is set in advance by the alarm driver  20 , and at the same time, only the received message data is displayed in the display  19  by the display driver  18  (step S 111 ). 
     After the display, by repeatedly determining whether or not a touching operation to instruct the reset of the key input  21  has been performed (step S 112 ), or whether or not the timer  173  in the CPU  17  has ended the clocking of the specified time to perform the receiving report (step S 114 ), the resetting operation and the time up of the timer  173  are waited for. 
     Then, if it is determined at step S 112  that a reset is detected, it means that a key operation has been performed within the specified time to perform the receiving report, and therefore, after resetting the clocking operation by the timer  173 , the report made by driving at least one of the speaker  22 , LED  23 , and vibrator  24  with the alarm driver  20 , is stopped, and the display is shifted to a display only of the received message data (step S 113 ). The state returns to a waiting state from step S 101 , again. 
     Furthermore, in the case where it is determined at step S 114  that the timer  173  in the CPU  17  has ended the clocking of the specified time to perform the receiving report, it means that the specified time to perform the receiving report has elapsed without performing any key operation of the key input  21 . Therefore, the report made by driving at least one of the speaker  22 , LED  23 , and vibrator  24  with the alarm driver  20  is stopped, and at the same time, “1” is set only to the unconfirmation flag F 31  corresponding to the received message data stored in the received message area RM. In the meantime, the received message data which has been displayed in the display  19  up to that time is stopped, and instead of that, an icon (not shown) showing the presence of an unconfirmed message is displayed in the display  19  (step S 115 ). The state returns to a waiting state from step S 101 , again. 
     Furthermore, in the case where at step S 109 , there are coincident lower 4 digits of the telephone number in the telephone number directory area TL, the corresponding name is read out of the telephone number directory area TL as a key word of conformity (or partial conformity) (step S 116 ). The retrieving is performed in each of the areas RM, TL, SC, and MM of the RAM  15  by the key word (step S 117 ). At this moment, the flags F 30 , F 4 , F 5 , and F 6  of each area are also simultaneously referred to. 
     This step S 117  is also immediately performed, in the case where it is determined at step S 107  that such retrieved contents that “1” is set to the flag F 1  at the area DMA in the data management area DM, is the key word including the telephone number. As a result of the retrieving, it is determined whether or not the corresponding data is present (step S 118 ). If not, step moves to the processing of the receiving report and the display using only the received message data from step S 110 . 
     Furthermore, in the case where it is determined at step S 118  that the corresponding data is present, the storing address of the received message data, the detection data used for retrieving, and the related key word are written and set in the area DMC of the data management area DM and the application loader  176  reads out the viewer  163  of the ROM  16  and loads it in the working memory  175  (step S 119 ). 
     After that, the corresponding address LA and the associated data storing address are set and registered in the area DMD of the data management area DM and “1” is set to the flag F 2  (step S 120 ). 
     Next, the number of items of associated data obtained by the retrieving at step S 117 , is counted, and the windows corresponding to that number are developed and displayed on the label display section  191  in the display  19  in the form of adding an icon showing the label corresponding to the kind of each data (step S 121 ). 
     Furthermore, the clocking of the specified time of the receiving report by the timer  173  in the CPU  17  is started, and in the meantime, the presence of receiving of a message is reported by driving at least one of the speaker  22 , LED  23 , and vibrator  24  which is previously set by the alarm driver  20 , and at the same time, a display where the received message data is made to be the head end window, is performed by the display driver  18  in the display  19  (step S 122 ). 
     After this display, by repeatedly determining whether or not a touching operation to instruct the reset of the key input  21  has been performed (step S 123 ), or whether or not the timer  173  in the CPU  17  has finished the clocking of the specified time to perform the receiving report (step S 133 ), the operation of reset and the time up of the timer  173  are waited for. 
     Then, in the case where it is determined at step S 133  that the timer  173  in the CPU  17  has finished the clocking of the specified time to perform the receiving report, it means that the specified time to perform the receiving report has elapsed without performing any key operation of the key input  21 . Therefore, the report made by driving at least one of the speaker  22 , LED  23 , and vibrator  24  with the alarm driver  20  is stopped, and at the same time, “1” is set to both the flag F 30  corresponding to the received message data stored in the received message area RM and the unconfirmation flag F 31  (step S 134 ). The contents which has been displayed in the display  19  up to that time is stopped (step S 135 ). The state returns to the waiting state from step S 101 , again. 
     If it is determined at step S 123  that a reset has been detected, it means that a key operation has been performed within the specified time to perform the receiving report. Therefore, after resetting the clocking operation by the timer  173 , the report made by driving at least one of the speaker  22 , LED  23 , and vibrator  24  with the alarm driver  20  is stopped, and “0” is set to the unconfirmation flag F 31  at the corresponding data part of the received message area RM to release the unconfirmed state, and in the mean time, a plurality of windows including the received message data are developed and displayed, again (step S 124 ). 
     At this moment, the part corresponding to the key word is discriminated by using, for example, reversing, under line, or the like to be displayed. 
     FIG. 28 shows the display screen of the display  19  at this moment, and an image is displayed in the window, where the message (contents) “I drafted meeting report,” the sender “Taro NOMURA,” and the reception day and time “97.11.15 17:00” are printed as the received message data on the card as window to which the label of “envelope” positioned at the head end is added, among 5 cards to which each of the icons of “envelope” showing the received message data, “memo pad” showing the memo data, “clock” showing the schedule data, and “(telephone) receiver” showing the telephone number directory data, is added as a label on the label display section  191 . 
     In this case, to the part “NOMURA” in the sender “Taro NOMURA,” the underline display is applied, and on the other hand, the guide message “registration will be performed ? Y/N” is displayed, which urges the instruction of whether the received message data should be displayed in the window after this as the associated data or not. 
     If the user operates “Y” to instruct registration, or “N” to instruct no registration according to the guide message, the contents are determined next to that by determining whether the instruction of the registration has been detected or not. (step S 125 ). 
     If it is determined that the “Y” is operated, it means that the registration of the window display of the received message data has been instructed, and therefore, “1” is set to the corresponding flag F 30  of the message data stored in the received message area RM (step S 126 ). 
     If it is determined at step S 125  that not “Y” but “N” has been operated, it means that such an instruction that the window display of the received message data from now should not be registered, has been issued, and therefore, “ 0 ” is set to the corresponding flag F 30  of the message data stored in the received message area RM (step S 126 ). 
     After that, by repeatedly determining whether there is an input to indicate the label parts of a plurality of windows displayed in the label display section  191 , by a touching operation at the key input  21  or not (step S 128 ), or whether the timer  173  in the CPU  17  has ended the clocking of the specified time or not (step S 132 ), which is similar to the above description, the indication of the label parts and the time up of the timer  173  are waited for. 
     In the case where it is determined at step S 132  that the timer  173  in the CPU  17  has ended the clocking of the specified time, it means that the specified time has elapsed without performing any indicating operation at the label part of each window, and therefore, the contents which have been displayed in the display  19  up to that time, are stopped (step S 135 ), and the state returns to a waiting state from step S 101 , again. 
     Furthermore, in the case where it is determined at step S 128  that one of the respective label parts of a plurality of windows has been indicated by a touching operation, the area DMD of the data management area DM is referred to by the viewer, and the corresponding data is read out of the telephone number directory area TL, the schedule data area SC, or the memo data area MM of the RAM  15  by using the associated data storing address of the corresponding data, and the display is performed so that the data may be the window at the head end (step S 129 ). 
     FIG. 29 shows the data displayed in the case where the label part of “(telephone) receiver” showing the telephone number directory data is operated from the state shown in FIG. 28, and here, the associated data storing address “4900” is read out of the area DMD of the data management area DM, and by using the address, “private data 2” of the telephone number, the name, the address, and the like which are the telephone number directory data of Mr. “Taro NOMURA” are read out of the address “4900” and so on of the telephone number directory area TL, and are displayed in the display  19  as the head end window. 
     Under the display state like this, furthermore, the detection of an instruction by a touching operation of the label part of the window displayed at the head end (on the label display section  191 ), is waited for (step S 130 ), and when it is determined that detection has been performed, the mode shifts from the read out mode of the received message data to a mode associated with the instructed label part, and the contents stored in the register  174  are transmitted to the areas DMC, DMD of the data management area DM, and the application loader  176  reads out the application program corresponding to the mode associated with the instructed label part, in addition to the viewer, from the application program memory  162  of the ROM  16 , and loads them in the working memory  175 . 
     That is, the step moves to the operation in this associated mode while keeping the window display (step S 131 ). 
     If it is determined at step S 101  that a selective operation of a mode directly performed by the key input  21  has been detected from the state of waiting for the receiving, whether the selected mode is the read out mode of the received message data or other modes, is determined, next to that (step S 140 ). 
     If it is determined that the mode selected here is the read out mode of the received message data, the message data in which “1” is set to the unconfirmation flag F 31 , is retrieved in the received message area RM of the RAM  15  (step S 141 ), and after that, whether there is a message data in which “1” is set to the flag F 31  or not is determined (step S 142 ), and in the case where it is determined that there is one, the message data in which “1” is set to the flag F 31 , is preferentially read out (step S 143 ). 
     Furthermore, in the case where it is determined that there is no message data in which “1” is set to the flag F 31 , the newest one is read out according to the contents of the reception day and time of each message data (step S 144 ). 
     Then, regardless of the presence or absence of the message data in which “1” is set to the flag F 31 , the read out message data is analyzed (step S 145 ), and whether “1” is set to the corresponding flag F 30  or not is determined (step S 146 ). 
     If it is determined that “1” is set to the flag F 30  of the corresponding message data, the received message storing address registered in the area DMC of the data management area DM is referred to, and the contents of the corresponding address LA are read out (step S 147 ). 
     Then, by using the read out corresponding address LA, all associated data storing addresses in which “1” is set to the flag F 2  in the area DMD of the data management area DM, are read out (step S 148 ), and by using the read out addresses, the corresponding data is read out of the received message area RM, the telephone number directory area TL, the schedule data area SC, and the memo data area MM, so that a plurality of windows corresponding to the number of items of associated data may be developed and displayed in the display  19  (step  149 ). 
     Then, after starting the widow display corresponding to the associated data, whether the instruction for releasing the registration of the window display has been detected or not is determined (step  150 ), and only in the case of determining that the instruction has been detected, “0” is set to the flag F 30  of the corresponding received message data of the received message area RM (step S 151 ), and after that, the step moves to the processing of waiting for the instruction of the label part of each window and the time up of the timer  173 , from step  128 . 
     Furthermore, in the case where it is determined at step S 146 , as the result of the analyzing of the read out message data that not “1” but “0” is set to the flag F 30 , a plurality of window displays by the associated data are not performed, and while displaying only the read out received message data in the display  19  (step S 152 ), the read out mode of the received message data is stopped, and the performance of the selective operation for shifting to the original receiving waiting state, is waited for (step  153 ). 
     Then, when it is determined that the selective operation has been performed, the read out mode is stopped, and the state moves to the waiting state from step S 101 , again according to the operation. 
     Furthermore, in the case where it is determined at step S 140  that the mode directly selectively operated by the key input  21  from the state of waiting for the receiving is a mode other than the read out mode of the received message data, whether the mode is the setting mode of a key word, or one of the telephone number directory mode, the schedule mode, and the memo mode, is determined, next to that (step S 161 ). 
     If it is determined that the mode is one of the telephone number directory mode, the schedule mode, and the memo mode, the application loader  176  reads out the corresponding application program from the application program memory  162  of the ROM  16 , and loads that in the working memory  175 , and in the state where the initial screen display of each mode is displayed in the display  19  (step S 162 ), whether the selective operation for newly performing the registration of the data has been performed by the key input  21  or mot is detected (step S 163 ). 
     If it is determined that the operation has been performed, continuously, in the sate where the screen for inputting the data is displayed in the display  19  instead of the initial screen (step S 164 ), while performing the display processing associated with the data of each item which is input in turn (step S 165 ), the input of the data is finished, and by repeatedly performing the processing of determining whether an instruction of registration has been detected or not (step S 166 ), the detection of an instruction of registration of the data is waited for. 
     Then, when it is determined that an instruction of registration has been detected, a guide message to prompt the selection of whether the associating with the message data should be performed or not, is displayed, next to that (step S 167 ), and then, whether the instruction to perform the associating has been issued according to that display or not, is determined (step S 168 ). 
     When it is determined that the instruction to perform the associating has been issued, “1” is set to the flag F 4  of the corresponding data of the telephone number directory area TL, if the selected mode is the telephone number directory mode and the input data is the telephone number directory data, or “1” is set to the flag F 5  of the corresponding data of the schedule data area SC, if the selected mode is the schedule mode and the input data is the schedule data, or “1” is set to the flag F 6  of the corresponding data of the memo data area MM, if the selected mode is the memo mode and the input data is the memo data (step S 169 ), and then, the step returns to the processing from step S 162 , again for preparing for the next data input. 
     Furthermore, when it is determined at step S 168  that an instruction so as not to perform the associating of the received message data corresponding to the input data, has been issued, “0” is set to the flag F 4  of the corresponding data of the telephone number directory area TL, if the selected mode is the telephone number directory mode and the input data is the telephone number directory data, or “0” is set to the flag F 5  of the corresponding data of the schedule data area SC, if the selected mode is the schedule mode and the input data is the schedule data, or “0” is set to the flag F 6  of the corresponding data of the memo data area MM, if the selected mode is the memo mode and the input data is the memo data, contrary to step S 169  (step S 170 ), and then, the step returns to the processing from step S 162 , again for preparing for the next data input. 
     Furthermore, when it is determined at step  163  that the selective operation for newly performing the registration of the data is not performed, the editing or deletion of the previously registered data should be performed next to that, and whether the instruction thereof has been detected or not is determined (step S 171 ), and if it is not detected, the step returns to the processing from step S 162 , again. 
     Then, if it is determined at step S 171  that the instruction of editing or deletion of the data has been detected, the corresponding data is read out of the telephone number directory area TL, the schedule data area SC, or the memo data area MM according to the continuous input operation, and in the state of displaying the data in the display  19  (step S 172 ), while performing the display processing associated with the data of each item which is input and edited, or stopped in turn (step S 173 ), by repeatedly performing the processing of determining whether the determining instruction of the contents of the data has been detected or not (step S 174 ), the detection of the determining instruction of the data is waited for. 
     Then, at the time of determining that the determining instruction has been detected, it is determined whether “1” is set to the flag F 4  of the corresponding data of the telephone number directory area TL, or to the flag F 5  of the corresponding data of the schedule data area SC, or to the flag F 6  of the corresponding data of the memo data area MM, depending on the mode (step S 175 ). 
     If it is determined that “1” is set to the flag, the guide message to prompt the selection of whether or not the associating with the message data should be performed, is displayed (step S 176 ), and then, it is determined whether or not the instruction to perform the associating has been issued according to that display (step S 177 ). 
     If it is determined that the instruction to perform the associating has been issued, the step returns to the processing from step S 162 , again for preparing for the next data input. 
     If it is determined at step S 177  that the instruction so as not to perform the associating of the received message data corresponding to the input data, has been issued, “0” is set to the flag F 4  of the corresponding data of the telephone number directory area TL, if the selected mode is the telephone number directory mode and the input data is the telephone number directory data, or “0” is set to the flag F 5  of the corresponding data of the schedule data area SC, if the selected mode is the schedule mode and the input data is the schedule data, or “0” is set to the flag F 6  of the corresponding data of the memo data area MM, if the selected mode is the memo mode and the input data is the memo data (step S 178 ). 
     After that, “0” is set to the flag F 2  of the associated data in the area DMD of the data management area DM (step S 179 ). After resetting the number of items of associated data in the area DMD (step S 180 ), the step returns to the processing from step S 162 , again for preparing for the next data input. 
     Furthermore, in the case where it is determined at step S 175  that “1” is not set to the flag F 4  of the corresponding data of the telephone number directory area TL, or to the flag F 5  of the corresponding data of the schedule data area SC, or to the flag F 6  of the corresponding data of the memo data area MM, depending on the mode, the guide message to prompt the selection of whether or not the associating with that message data should be performed, is displayed (step S 181 ). Then, it is determined whether or not the instruction to perform the associating has been issued according to that display (step S 182 ). 
     When it is determined that the instruction to perform the associating has been issued, “1” is set to the flag F 4  of the corresponding data of the telephone number directory area TL, if the selected mode is the telephone number directory mode and the input data is the telephone number directory data, or “1” is set to the flag F 5  of the corresponding data of the schedule data area SC, if the selected mode is the schedule mode and the input data is the schedule data, or “1” is set to the flag F 6  of the corresponding data of the memo data area MM, if the selected mode is the memo mode and the input data is the memo data (step S 183 ). The step returns to the processing from step S 162 , again for preparing for the next data input. 
     Furthermore, when it is determined at step S 182  that the instruction so as not to perform the associating of the received message data corresponding to the input data, has been issued, the step returns to the processing from step S 162 , again for preparing for the next data input. 
     FIG. 27 shows the stored contents of the data management area DM in the case where the processing is performed while shifting to each mode after the receiving of the message data, which is also shown in FIG.  26 . During the processing of the receiving, the received message data is written in the register  174 , and it is understood that at the storing address “4200”of the received message area RM in the area DMC, the received message data in which the detecting object data is “4321” and the related key word is “NOMURA” is stored, and that there are “4” other data associated with that, in the received message area RM, the telephone number directory area TL, the schedule data area SC, and the memo data area MM. 
     Furthermore, in the case where it is determined at step S 161  that the selected mode is the keyword setting mode, the absence of the detection of the operation for escaping from the key word setting mode is confirmed (step S 192 ), in the state of displaying the initial screen display of the corresponding mode in the display  19  according to that operation (step S 191 ). By repeatedly determining whether or not the selective operation for newly performing the registration of a key word has been performed (step S 193 ), or whether or not the selective operation for performing editing/deletion of the previously registered key word has been performed (step S 199 ), either of them is waited for. 
     Then, if it is determined at step S 193  that the operation for newly performing the registration of a key word has been performed, the screen for inputting a key word is displayed in the display  19  instead of the initial screen (step S 194 ). The display processing associated with the data of the key word which is input is performed (step S 195 ). By repeatedly performing the processing of determining whether or not the instruction of the registration has been detected (step S 196 ), the detection of the instruction of the registration of the data composing the key word is waited for. 
     Then, when it is determined that the instruction of the registration has been detected, the data of the input key word is written and set in the area DMB of the data management area DM as the retrieving object data (step S 197 ). “1” is set to the corresponding flag F 1  of the area DMB (step S 198 ). The step returns to the processing from step S 193 , again for receiving the input of the next key word. 
     If it is determined at step S 199  that the selective operation for performing editing or deletion of the previously registered key word has been performed, the key word to be the object of editing or deletion according to the input operation is read out among from the retrieving object data of the area DMB of the data management area DM (step S 200 ). 
     Then, while performing the display processing associated with the contents which are subjected to input and editing in turn for the data of the read out key word (step S 201 ), the detection of the instruction of determining by editing/deletion of the key word is waited for, by repeatedly performing the processing of determining whether the instruction to determine the contents has been detected or not (step S 202 ). 
     Then, when it is determined that the determining instruction has been detected, it is determined whether or not “1” is set to the flag F 1  for the corresponding retrieving object data of the area DMB of the data management area DM (step S 203 ). 
     If it is determined here that “1” is set to the flag F 1 , the data of the key word whose contents are edited as the retrieving object data is again written and set in the area DMB of the data management area DM, and a guide message for prompting the selection of whether or not the retrieving by the key word should be performed when the message is received, is displayed (step S 204 ). In the case where such an instruction that the data of the key word should not be edited but be stopped, has been issued, the corresponding retrieving object data is stopped from the area DMB instead of the writing-in setting. 
     Then, it is determined whether or not the instruction to perform the retrieving has been detected according to that display (step S 205 ). If it is determined that the instruction to perform the retrieving has been detected, the step returns to the processing from step S 193  again for receiving the next key word input. 
     If the instruction to perform the retrieving by the key word when the message is received, is not detected at step S 205 , “1” which has been set to the flag F 1  of the corresponding data of the area DMB of the data management area DM, is reset to “0” (step S 204 ). After that, the stored contents respectively including the corresponding addresses LA of the areas DMC and DMD of the data management area DM, are stopped (step S 207 ). Then, the step returns to the processing from step S 193  again for receiving the next key word input. 
     If it is determined at step S 203  that “1” is not set to the flag F 1  for the corresponding retrieving object data of the area DMB of the data management area DM, the data of the key word whose contents are edited, is again written and set into the area DMB of the data management area DM, as the retrieving object data, and the guide message to prompt the selection of whether or not the retrieving by the key word should be performed when the message is received, is displayed (step S 208 ). If such an instruction that the data of the key word should not be edited but be stopped, has been issued, the corresponding retrieving object data is stopped from the area DMB instead of the writing-in setting. 
     Then, it is determined whether or not the instruction to perform the retrieving according to that display has been detected (step S 209 ). If it is determined that the instruction to perform the retrieving has been detected, “1” is set to the flag F 1  of the corresponding data of the area DMB (step S 210 ). Then, the step returns to the processing from step S 193  again for receiving the next key word input. 
     If the instruction to perform the retrieving by the key word when the message is received, has not been detected at step S 209 , the step returns to the processing from step S 193  again for receiving the next key word input. 
     Furthermore, at step S 131  and afterward, in each mode, the newly input and created data can be registered as the transmission data. 
     FIG. 30 is a flow chart showing a series of flow up to new input/registration/transmission processing of the data after shifting to each mode. 
     In this flow chart, when shifting to the operation in the associated mode from step S 131 , the application program corresponding to that mode is loaded in the working memory  175  while keeping the window display (step S 211 ). 
     In this state, it is determined whether or not the selective operation to newly perform the registration of the data has been performed by the key input  21  (step S 212 ). 
     If it is determined that the operation has been performed, the screen for inputting the data is displayed in the display  19  instead of the initial screen, while performing the data creation processing and display processing by the continuous inputting (step S 213 ) and the data creation processing is finished. By repeatedly performing the processing of determining whether or not the registration instruction has been detected (step S 214 ), the detection of the registration instruction of the data is waited for. 
     Then, when it is determined that the registration instruction has been detected, the guide message to prompt the selection of whether or not the data should be sent through the communication network is displayed (not shown), and after that, it is determined whether or not the transmission request has been performed (step S 215 ). 
     If it is determined that the transmission request has been performed, the conversion program stored in the ROM  16  is further loaded in the working memory  175 , and the created data is converted into the data corresponding to the transmission network for sending and is transmitted to the transmission buffer  26 . Furthermore, at this moment, the data associated with the other end to which the data is sent, is read out of, for example, the telephone number directory area TL, and is set in the transmission buffer  26  (step S 216 ), and is made to be in the storage keeping state (step S 217 ). 
     After that, by determining whether or not the specified key operation of the key input  21  has been detected, the execution of transmission is determined, and if the transmission execution request is detected, the data is transmitted from the transmitter  27  (step S 219 ), and the step returns to step S 211 . 
     If the transmission execution request is not detected, the flow returns to the storage keeping state (step S 217 ). 
     Furthermore, even if the transmission execution request of the created data is not detected at step S 215 , the registration processing of the data is performed (step S 221 ). 
     Accordingly, by making it possible to perform such a transmission processing, a desired data can be created and edited in the corresponding mode while referring to the associated data of other modes by the viewer, and the transmission of that data can be transmitted. 
     Furthermore, the transmission processing can be executed between step S 165  and step S 166 , or step S 174  and step S 175  in FIG.  24 . 
     Furthermore, in the data management area DM, a new area DME may be provided as shown in FIG. 31, instead of the area arrangement shown in FIG.  16  and FIG.  27 . In this case, it is arranged that in the area DME, an icon of the label can be set, corresponding to the storing address of the associated data, and therefore, it is arranged that in the display at the time of receiving of the message data, an icon of the label of one&#39;s own making can also be displayed, other than the label previously set in each mode. 
     Thus, in the state where the data associated with the receiving message data is displayed in the window, not only it can be displayed in the state where to which mode each data belongs, is visually understandable, but also it is possible to immediately shift from the state of being displayed in the window to the corresponding mode, so that a more practical operational environment can be achieved. 
     Third Embodiment 
     In the second embodiment, it is arranged that in addition to the first embodiment, an icon is displayed as the label of each window at the time of window display, so that the shift to the operation of each mode may be performed while keeping the window display, but furthermore, in the third embodiment, the case where the display priority can be set as for the window display, will be described in detail. 
     The third embodiment in the case where the present invention is applied to a paging receiver which has the function of an electronic notebook and conforms to the standard RCRSTD-43, will be described below by referring to drawings. 
     By the way, the present embodiment is basically similar to that shown in FIG. 14, and therefore, the same numeral is applied to the same part, and the description thereof will be omitted. 
     FIG. 32 shows the stored state of each application program which is stored in the application program memory  162  like a table. 
     In this figure, in each application program, the minimum number of bytes required for the working memory during the loading of the program is stored in the correlated state. 
     That is, the load of the CPU  17  required for loading the program is smaller and the mode shift is faster as this number of bytes is smaller. It is expressed that on the contrary, the load of the CPU  17  required for loading the program is larger and the mode shift is slower as the number of bytes is larger. 
     Furthermore, in the case of the viewer, which is not shown in the figure, only the data display is performed, and therefore, the minimum number of executive bytes thereof is substantially smaller than that of these application programs. 
     FIG. 33 to FIG. 36 respectively show the stored contents of the received message area RM′, telephone number directory area TL′, schedule data area SC′, and the memo data area MM′ which are similar to those in the second embodiment. 
     In FIG. 33 to FIG. 36, the third embodiment is different from the second embodiment, in that the data volume (bytes) is stored and managed corresponding to each data in the received message area RM′ and schedule data area SC′, and that the data volume and the day and time of registration of the data are stored and managed corresponding to each data in the telephone number directory area TL′and memo data area MM′. 
     FIG. 37 shows the arrangement and the stored contents of the data management area DM′ in the third embodiment. 
     Similarly to the second embodiment, it comprises 4 areas DMA to DMD, but in addition to them, it further comprises an area DMF. 
     In the area DMF, an item which defines the display priority of the window display (overlap display) of the associated data if a plurality of associated data of the message data are detected when a message is received, and a flag W are stored in the correlated state. 
     That is, during the window display of a plurality of associated data, if “1” is set to the flag W corresponding to “the number of bytes for executing application,” the overlap display of the window is performed in such a way that one in which the load of the CPU  17  for loading is lighter, in the application programs corresponding to a plurality of associated data to be displayed, is preferentially displayed. 
     If “1” is set to the flag W corresponding to “data volume,” the priority of the overlap display of the window is determined according to the volume of a plurality of associated data to be displayed. 
     If “1” is set to the flag W corresponding to “schedule start day and time/registration day and time/reception day and time,” by referring to the day and time information (start day and time if it is the schedule data, registration day and time if it is the memo data or the telephone number directory data, and reception day and time if it is the received message data) of the plurality of associated data to be displayed, the overlap display of the window is performed in such a way that one having the latest day and time is preferentially displayed. 
     By the way, in the flag W, the setting can properly be changed by detecting the operation from the key input  21 , which is not described in detail. 
     FIG. 38 shows the contents of the processing from the message receiving state in the third embodiment, which is a flow chart of the processing performed between step S 120  and step S 122  of FIG. 22 in the second embodiment. 
     In FIG. 38, if “1” is set to the flag F 2  (step S 120 ) after setting and registering the corresponding address LA and the associated data storing address in the area DMD of the data management area DM, the number of items of associated data obtained by the retrieving at step S 117  is counted (step S 221 ). 
     Then, it is determined whether or not the number of items of associated data is 1 or more (step S 222 ). If it is “1”, the window corresponding to the associated data is developed and displayed in the display  19  in the form where an icon showing the label corresponding to the kind of each data is also added (step S 224 ). 
     If the number of items of associated data is more than “1”, the priority of the window display is determined according to the priority by which “1” is set to the flag W in the area DMF (step  223 ). After that, the windows corresponding to these associated data are developed and displayed in the display  19  in the form where an icon showing the label corresponding to the kind of each data is also added (step S 224 ). 
     FIG. 39 shows the display screen of the display  19  at this moment, and 5 cards (windows) to which the respective icons of “envelope” showing the received message data, “envelope” showing the past received message data, “memo pad” showing the memo data, “telephone receiver” showing the telephone number directory data, and “clock” showing the schedule data, are added as the label, are displayed in the overlapped state, in the order in which the number of executive bytes of the application program is smaller. 
     According to the present invention, it is easy to confirm whether or not data associated with input data is stored in a memory (RAM  15 ) of the device when the data is input and to refer the associated data. 
     Since a label or icon indicating the type or the identification number of the associated data is displayed if a plurality of associated data are present, each of the associated data can be easily referred to even if a plurality of associated data are searched for. 
     Further, a label or icon indicating the type or the identification number of the associated data is displayed according to the priority of each associated data relating to the day and time when the data is stored, the size (or volume) of the data, and the load of the CPU processing the data. Therefore, it is easy to understand the status of the associated data. 
     Moreover, it is possible to select whether or not data stored in the memory (RAM  15 ) is displayed as the associated data. 
     Since the input data and the associated data are displayed as a window and the window display is easily switched in a simple operation. Therefore, a load for display is small so that a portable data processing device can display them without causing any trouble. 
     According to the present program for editing the associated data, the associated data is displayed first and then loaded. Thus, it is possible to decrease the load of the device and the system. 
     Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the present invention in its broader aspects is not limited to the specific details, representative devices, and illustrated examples shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents. For example, in the second and third embodiments, it is arranged that the application loader  176  loads the viewer  163  during the window display of the associated data at the time of receiving the message data, and loads the corresponding application program when the processing has shifted to step S 162  (FIG.  24 ). 
     However, in the case where the viewer  163  is not stored in the ROM  16 , it is also possible that among the application programs corresponding to the associated data, a program required only for the display is loaded during the display of the associated data at the time of receiving the message data, and all these application programs are loaded when the processing has shifted to step S 162  (FIG.  24 ). 
     Furthermore, in the first to third embodiments, the case where the present invention is applied to a paging receiver which has the function of an electronic notebook and conforms to the standard RCRSTD-43, is described, but the present invention is not limited to this, and it can also easily be applied to an electronic equipment storing the data which may be associated with the input message data, such as a digital portable telephone or a PHS (Personal Handyphone System: simplified cordless telephone) which can store, for example, the telephone number directory data and can perform sending and receiving of the electronic mail. 
     Furthermore, it is also possible that the contents of the control (window display control, shifting display control) are previously stored in the portable storage medium  29 , and are read out by the storage medium driver  28  to be written in the ROM  16 , if needed. 
     Furthermore, the present invention can be carried out in various modifications in the range in which they do not depart from the true spirit and scope of the invention. 
     Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
