The blinking pattern signal generator 22 generates a blinking pattern signal under the control of the controller 15 when a call is received, and the generated blinking pattern signal is amplified by the amplifier 29 and then the LED 30. Is driven to emit light, and the calling state is notified by a flashing pattern of light.

The display buffer 24 sequentially stores the character pattern data read from the character generator 23 in accordance with a control instruction including a color code from the control section 15, and outputs the stored content to the color display section 31.

The color display section 31 is composed of, for example, a color liquid crystal panel and its drive circuit, and displays and outputs display data such as message data sent from the display buffer 24 as a color image. The input locus etc. are also displayed by the pen input by the writing operation in.

Next, a first operation example of the above embodiment will be described with reference to FIGS. 3 and 4. In FIG. 3, the paging receiver 1a on the calling side sends message data including image data of a drawn image to the paging receiver 1b on the responder side, and the paging receiver 1b corrects the message data. Paging receiver 1
This shows the contents of the processing operation of each of the paging receivers 1a and 1b when replying to a. First, at the beginning of the processing, message data including a drawn image as shown in FIG. 4A is created in the paging receiver 1a. (Step A1).

In FIG. 4 (1), if the character "Tanashi station" is the key input section 16 and the other map figures are pen input by the pen input section 17 by freehand, the message data is the key code. The data is composed of a combination of data and image data, and the created message data is temporarily stored in the RAM 18.

Next, in the paging receiver 1a, the speaker 26 is brought into contact with the transmitter of the telephone 2 as shown in FIG. The call number and the message data are sequentially converted into the DTMF signal by the DTMF signal generating section 19 by inputting with the key and the message data stored in the RAM 18 is designated and then the transmission is instructed. As described in FIG. 1, the data is transmitted to the paging receiver 1b via the telephone 2, the telephone line network 3, the paging service company 4, and the wireless base station 5 (step A2).

In the paging receiver 1b, the ID-ROM
Intermittent reception is performed in a time division cycle represented by the frame data stored in 14, and the call waiting of the own device is waited by the reception judgment of the address data assigned to the own device.
When a call is received by the transmission process of step A2,
First, the message data received following the call is stored in the RAM 18 (step B1), and subsequently, the character generator 23 reads the character pattern data of the corresponding character from the code data forming the received message data, and the image is also displayed. The data is expanded and stored in the display buffer 24, and both are displayed in a single color on the color display unit 31, for example, "black" (step B2).

In the paging receiver 1b, in order to modify the received message data next, for example, a color code of "red" is designated by the key input unit 16 (step B3), and then the pen input unit is specified. As shown in FIG. 4 (2), when the writing operation is performed on the color display unit 31 to make a correction, the input locus based on the image data is colored on the color display unit 31 by the color code specified above. Displayed with, and RAM as correction data
It is stored in 18 together with the designated color code (step B4).

Next, assuming that the paging receiver 1b has been corrected, the speaker 26 is brought into contact with the transmitter of the telephone 2 as in the case of the paging receiver 1a shown in FIG.
By inputting the calling number of the paging receiver 1a with the key input unit 16, designating the corrected message data stored in the RAM 18, and then operating the transmission key for instructing a reply, the calling number and the correction are performed. The completed message data is sequentially converted into a DTMF signal by the DTMF signal generator 19, and the speaker 26, the telephone 2, the telephone line network 3,
It is returned to the paging receiver 1a via the paging service company 4 and the wireless base station 5 (step B5).

After the message data is transmitted, the paging receiver 1a performs intermittent reception at a time division cycle represented by the frame data stored in the ID-ROM 14, and judges whether the address data assigned to itself is received. Therefore, when a call is received by the transmission processing of the step B5, first, the message data received following the call is stored in the RAM 18 (step A3), and then the received message is received. The data is expanded and displayed on the color display unit 31 (step A4).

In this case, the portion of the message data transmitted by itself is displayed in, for example, "black" as in FIG. 4 (2), and the portion based on the correction data corresponds to the color code, for example, "black". Display in red.

FIG. 4C shows an example of the contents displayed on the color display section 31 of the paging receiver 1a at this time, and the same portion as that shown in FIG. 4A is "black".
In the figure, the portion newly added by the correction processing in the paging receiver 1b is displayed in a section of "red".

In this way, the corrected content is displayed by partially changing the color from the initial content with the arbitrary color designated by the respondent, so that the corrected position can be confirmed at a glance. be able to.

In the first operation example shown in FIGS. 3 and 4, the correction process based on the image data is shown, but the correction process based on the code data can also be applied. Next, a second operation example will be described with reference to FIGS.

FIG. 5 shows the paging receiver 1 on the calling side.
The paging receiver 1 in the case where the message data of the code data string is transmitted from the a to the paging receiver 1b on the responder side, the message data is corrected by the paging receiver 1b, and the message data is returned to the paging receiver 1a.
FIG. 6 (1) shows the contents of the processing operation of each of a and 1b.
It is assumed that message data is created by the code data string as shown in (step A11).

FIG. 6 (1) shows all message data created by key operation in the key input unit 16, and is composed of a data string of key codes. The created message data is once the message No. Is added and stored in the RAM 18.

Then, in the paging receiver 1a, the speaker 26 is brought into contact with the transmitter of the telephone 2 as shown in FIG. Is input and the message data stored in the RAM 18 is designated, and then the key operation for instructing the transmission is performed, whereby the calling number and the message number.
The message data attached with is converted into a DTMF signal by the DTMF signal generating section 19 in sequence, and the telephone 26, the telephone network 3, and the telephone line network 3 are transmitted from the speaker 26 as described above with reference to FIG.
It is transmitted to the paging receiver 1b via the paging service company 4 and the wireless base station 5 (step A12).

In the paging receiver 1b, the ID-ROM
Intermittent reception is performed in a time division cycle represented by the frame data stored in 14, and the call waiting of the own device is waited by the reception judgment of the address data assigned to the own device.
When a call is received by the transmission process of step A12, the message data received subsequently to the call is stored in the RAM 18 (step B11), and the character generator 23 handles the code data forming the received message data. By reading the character pattern data of the character to be stored, the message data is expanded and stored in the display buffer 24 at any time, and is displayed in a single color, for example, "black" on the color display unit 31 (step B
12).

In the paging receiver 1b, some correction is made by the key operation of the key input unit 16 in order to make a correction to the received message data (step B13). As shown, the numerical value "2 million" in Fig. 6 (1) is changed to "2.5 million".
In addition to rewriting, the character string "Please confirm" should be rewritten as "Please reconsider with the above numbers".

After such correction processing, this is judged only when the contents of the message data are actually corrected, and a predetermined reply protocol for the corrected message data stored in the RAM 18 is determined. (Steps B14, B15), and then paging receiver 1
Assuming that the correction is completed in step b, the speaker 26 is brought into contact with the transmitter of the telephone 2 as in the case of the paging receiver 1a of FIG. 1, and the calling number of the paging receiver 1a is input by the key input unit 16. Then, by designating the modified message data stored in the RAM 18 and then operating the send key for instructing a reply, the calling number and the modified message data are sequentially displayed by the DTMF signal generator 19.
It is converted into a TMF signal and is returned from the speaker 26 to the paging receiver 1a via the telephone 2, the telephone line network 3, the paging service company 4 and the wireless base station 5 (step B16).

After the message data is transmitted, the paging receiver 1a performs intermittent reception at a time division cycle represented by the frame data stored in the ID-ROM 14, and judges whether the address data assigned to itself is received. Therefore, when the call is received by the transmission process of the step B16, the message data received subsequently to the call is stored in the RAM 18
(Step A13), and then it is determined whether or not the received message data includes a reply protocol, that is, whether or not the received message data is a reply to the message data issued by itself (step A1).
4).

When the reply protocol is not added to the received message data, the message data is merely normal message data, or the content of the message data even if it is a reply to the message data issued by itself. Since no modification has been made, the character pattern data of the corresponding character is read from the code data forming the received message data by the character generator 23 as it is to expand the message data at any time and display buffer 24. Then, the color display unit 31 displays it in a single color, for example, "black" (step A17).

When it is determined that the reply protocol is added to the message data received in step A14, the message data is a reply to the message data issued by the own device, and the contents are not corrected in any way. Since it is added, RAM18
Message No. stored in The contents of the transmitted message data and the contents of the received message data that are the same are compared and collated (step A15), and the portion of the received message data different from the original message data that has been modified is different from the other portion. Different colors, for example, "red" are displayed (step A16).

FIG. 6C shows an example of the contents displayed on the color display section 31 of the paging receiver 1a at this time. The same portion as that shown in FIG. 6A is "black".
3 shows a state in which the portion changed by the correction process in the paging receiver 1b is displayed in red.

As described above, by displaying only the content portion corrected by the respondent by changing the color from the initial content, the responder can confirm the corrected position at a glance. Further, since the responder side only has to send back the corrected data, the process on the responder side is simplified.

In the second operation example shown in FIGS. 5 and 6, the correction process using the code data has been described, but the correction process using the image data as shown in FIG. 4 can also be applied.

In the first operation example of FIGS. 3 and 4 and the second operation example of FIGS. 5 and 6, both the message data received by the paging receiver 1b on the responder side are subjected to correction processing. Although it is shown that the applied result is returned to the paging receiver 1a on the calling side as it is, the repair process when only the correction content is returned will be described with reference to FIGS. 7 and 8 as a third operation example. To do.

FIG. 7 shows the paging receiver 1 on the calling side.
The paging receiver 1 in the case where the message data of the code data string is transmitted from the a to the paging receiver 1b on the responder side, the message data is corrected by the paging receiver 1b, and the message data is returned to the paging receiver 1a.
FIG. 8 (1) shows the contents of the processing operation of each of a and 1b.
It is assumed that message data is created by the code data string as shown in (step A21).

FIG. 8 (1) shows all message data created by key operation in the key input unit 16, and is composed of a data string of key codes. Is added and stored in the RAM 18.

Next, in the paging receiver 1a, the speaker 26 is brought into contact with the transmitter of the telephone 2 as shown in FIG. Is input and the message data stored in the RAM 18 is designated, and then the key operation for instructing the transmission is performed, whereby the calling number and the message number.
The message data attached with is converted into a DTMF signal by the DTMF signal generating section 19 in sequence, and the telephone 26, the telephone network 3, and the telephone line network 3 are transmitted from the speaker 26 as described above with reference to FIG.
It is transmitted to the paging receiver 1b via the paging service company 4 and the wireless base station 5 (step A22).

In the paging receiver 1b, the ID-ROM
Intermittent reception is performed in a time division cycle represented by the frame data stored in 14, and the call waiting of the own device is waited by the reception judgment of the address data assigned to the own device.
When a call is received by the transmission processing of the step A22, the message data received following the call is first stored in the RAM 18 (step B21), and the character generator 23 handles the code data constituting the received message data. By reading the character pattern data of the character to be stored, the message data is expanded and stored in the display buffer 24 at any time, and is displayed in a single color, for example, "black" on the color display unit 31 (step B
22).

The paging receiver 1b waits for a pen input in order to make some correction by a writing operation of the pen input unit 17 in order to make a correction to the received message data (step B23). As shown in FIG. 8 (2), the numerical value “2” in FIG.
A strikethrough is added to the ", 000,000" portion and "250" is placed just above it.
The correction is made by adding the character "million" and the character "review" (step B24).

The correction data based on the image data added by the above-described correction processing is different from the message data based on the received code data, and a predetermined color reply protocol and the received message N.
o. After being added, the correction data and the original message data are combined and displayed in the color display section 31 (step B25).

After that, in the paging receiver 1b, the speaker 26 is brought into contact with the transmitter of the telephone 2 in the state in which the correction is completed, as in the case of the paging receiver 1a of FIG. 1, and the paging receiver 1a is called. By inputting a number in the key input unit 16, designating only the correction data stored in the RAM 18, and then operating the transmission key for instructing a reply,
Protocol and message N for calling number and color reply
o. Only the correction data shown in FIG. 8 (3), to which is added, is sequentially converted into a DTMF signal by the DTMF signal generator 19 and is transmitted from the speaker 26 through the telephone 2, the telephone line network 3, the paging service company 4, and the wireless base station 5. To send a reply to the paging receiver 1a (step B26).

After the message data is transmitted, the paging receiver 1a performs intermittent reception at a time-division cycle represented by the frame data stored in the ID-ROM 14, and judges whether the address data assigned to itself is received. By this means, it waits for a call of its own machine, and when the call is received by the transmission processing of the step B26, the message data received following the call is first stored in the RAM 18
(Step A23), and it is then determined whether or not the received message data includes a color reply protocol, that is, whether or not the received message data is a reply to the message data issued by itself (step A23). A24).

When the color reply protocol is not added to the received message data, the message data is just normal message data. Therefore, the code data that constitutes the received message data is used as it is. Character generator 2
By reading the character pattern data of the corresponding character in 3, the message data is expanded as needed and stored in the display buffer 24, and is displayed in a single color, for example, "black" on the color display unit 31 (step A28).

When it is determined that the color reply protocol is added to the message data received in step A24, the message data is a reply to the message data issued by the device itself, and the contents are modified in some way. Will be added, so RA
Message No. stored in M18. Search for transmitted message data having the same (step A25),
The character pattern data of the corresponding character is read by the character generator 23 from the code data forming the retrieved message data, so that the message data is expanded as a pattern of a single color, for example, "black" at any time and stored in the display buffer 24. , The received image data of the correction data is developed as a pattern of a color different from the message data, for example, "red", and is synthesized and stored in the display buffer 24 (step A26). Then, the developed message is displayed on the color display unit 31. A composite image of the data and the corrected data is displayed (step A2
7).

FIG. 8 (4) exemplifies the contents displayed on the color display section 31 of the paging receiver 1a at this time, and the same portion as that shown in FIG. 8 (1) is "black".
3 shows a state in which the portion based on the image data newly added by the correction process in the paging receiver 1b is color-coded and displayed in "red".

In this way, by displaying only the content portion modified by the responder by changing the color from the initial content, it is possible for the responder to confirm at a glance the corrected position and receive the paging. Paging receiver 1 from device 1b
The data to be returned to a does not include the original message data, but only the image data of the corrected portion, so the amount of data required for the reply can be greatly reduced.

In the third operation example shown in FIGS. 7 and 8, the case where the code data is corrected by the image data has been described. However, the case where the image data is corrected by the image data as shown in FIG. Can be applied.

Further, although the above embodiment has exemplified the case where the present invention is applied to a wireless paging system using a paging receiver having a dial function, the present invention is not limited to this. The present invention is also applicable to a paging system or the like using FM multiplex broadcasting that multiplexes and broadcasts with message information, and can be variously modified without departing from the scope of the present invention.
