DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment when the present invention is applied to a radio paging system in accordance with an advanced radio paging system (RCR STD-43 standard) will be described with reference to the drawings.
[0020]
FIG. 1 shows a circuit configuration of a paging receiver as a portable terminal. In the figure, the paging receiver includes an antenna 1, a receiving unit 2, a decoder 3, a CPU 4, a received data processing circuit 5, a display driver 6, a display unit 7, a key input unit 8, an ID-ROM 9, a RAM 10, a ROM 11, and transmission data. By the memory 12, the notification driver 13, the LED 14, the speaker 15, the transmission buffer 16, the D / A conversion unit 17, the amplifier (Amp.) 18, the speaker 19, the connector 20, the infrared (Ir) transmission / reception unit 21, the bus B, etc. It is configured.
[0021]
The antenna 1 receives data transmitted from a transmission antenna of a paging center not shown here and outputs the data to the receiving unit 2.
[0022]
The receiving unit 2 is connected to the decoder 3 and is driven based on a control signal from the decoder 3 to demodulate and detect received data. The receiving unit 3 selects and outputs serial bit data to the decoder 3 in accordance with a binary or quaternary modulation method by incorporating a synchronizing unit of the received signal.
[0023]
The decoder 3 rearranges the binary or quaternary serial bit data input from the receiving unit 2 into 8-bit parallel data and outputs the rearranged data to the bus B. When the decoder 3 receives the detection signal output in the case of a match after collating the address data in the address field in the signal received by the CPU 4 with the address data registered in the ID-ROM 9, The receiving unit 2 is instructed to continuously receive all data in the vector field and message field of the frame in the signal including the address data.
[0024]
The reception data processing circuit 5 includes a deinterleave circuit, a buffer memory, a BCH decoder, and the like, and the buffer memory temporarily stores a maximum of one frame in its own frame in units of blocks until the end of incoming processing. The deinterleave circuit restores the binary or quaternary 8-bit parallel bit data output from the decoder 3 and stored in the buffer memory according to the respective frame patterns and restored (for each phase). Then, the BCH decoder 17 decodes the BCH code of the data held in the buffer memory and performs error correction processing.
[0025]
The CPU 4 analyzes the incoming bit data based on various control programs stored in the ROM 11 and performs overall control of each circuit unit in the paging receiver according to various control signals input from the key input unit 8. .
[0026]
The display driver 6 drives the display unit 7 based on display control information input from the CPU 4. The display unit 7 is configured by a dot matrix type liquid crystal panel having a display area (not shown), an EL backlight, and the like, for example, having a display area of 56 dots vertically by 90 dots horizontally, and is driven and controlled by the display driver 6. Then, information such as messages and images is displayed on the liquid crystal display panel.
[0027]
The key input unit 8 is, for example, a cursor for detecting mode switching operation or image selection operation such as ON / OFF switching of the power source, main switch for detecting determination of various settings in each mode, incoming call waiting mode, notification mode setting mode, etc. Key, memory key to detect message read operation based on stored message data, reset of incoming call notification, release key to detect mode release, and numbers, alphabets, hiragana, katakana, kanji, symbols, etc. For example, a keyboard having a QWERTY layout provided for character input is used, and various operation signals corresponding to the input operation of each key are output to the CPU 4.
[0028]
As shown in FIG. 2, the ID-ROM 9 has a frame number of a frame to be received set in the paging receiver, address data (32 bits) for call detection, and v2, v1, set in a vector field. v0 3-bit vector type, setting contents of the address data, paging type, flag F1 indicating presence / absence of corresponding image, file name of the image file when the flag F1 is set, and image of the file The management address is associated and stored.
[0029]
Here, the frame number data to be received is “7”, and the individual call address data #A can receive the NP type paging service. As the setting contents, the first call address for the basic call is stored according to the vector type. ing.
[0030]
Further, the frame number data to be received is '63', the individual paging address data #B can receive the IP type paging service, and the setting contents include the 2nd address for the first information service according to the vector type. I remember it.
[0031]
Further, for the individual call address data #C of the frame number “87” to be received, the IP type paging service is received, and the setting contents include the 3rd address for the second information service by the image according to the vector type. And "1" is set as the corresponding image flag F1. Here, the corresponding file name stores “ticket XX”, and the image management address stores “001”.
[0032]
Similarly, for the individual call address data #D of the frame number “103” to be received, the IP type paging service is received, and the setting content is the 4th address for the third information service by the image according to the vector type. And “1” is set as the corresponding image flag F1. Here, the corresponding file name is stored as “info xxx”, and the image management address is stored as “002”.
[0033]
As shown in FIG. 3, the RAM 10 includes a user information memory area UD, a telephone directory data memory area TD, an individual call message memory area PMD, an information providing service data memory area IMD, an image data management memory area IMM, and an image data storage area. I have IMGD.
[0034]
In the user information memory area UD, for example, as shown in FIG. 4, the name of the user who owns this paging receiver and the call number are stored in association with each other.
[0035]
As illustrated in FIG. 5, the telephone directory data memory area TD includes a registration number and a name, a telephone (calling) number, an address, and a paging type flag F2 that indicates whether or not the paging type is a possible paging type. Store multiple sets.
[0036]
As shown in FIG. 6, the information providing service data memory area IMD includes a message number and an incoming address, contents of information displayed as a headline, a corresponding image management address, and an incoming date and time as a set. Remember.
[0037]
As shown in FIG. 7, the image data management memory area IMM is an image management address and image capacity, a copy prohibition flag F3 indicating whether or not the image is prohibited from being copied, and a copy of the image. A copy flag F4 indicating whether the image is received, the file name of the image, and a bitmap image obtained by simplifying the image data of the binary monochrome image are associated with each other, and the received image is stored.
[0038]
The image data storage area IMGD stores original image data that is not simplified in association with the file name of the image.
[0039]
As shown in FIG. 8, the ROM 11 includes a program ROM memory area 111, a character generator (CG) memory area 112, a JIS8 code conversion table 113, an 8-bit / dot pattern conversion table 114, a shift JIS area table 115, and a free word table 116. It consists of
[0040]
The program ROM memory area 111 mainly stores an operation program for the CPU 4, a display control program, and other various programs.
[0041]
The character generator memory area 112 stores dot pattern data of full-width characters displayed as horizontal 12 × vertical 13 dots.
[0042]
The JIS8 code conversion table 113 is a table for converting bit data sequentially read in units of 8 bits from the bit data string received by the IP paging service into corresponding characters (characters) as shown in FIG. The designation information is stored and arranged in a matrix with upper 4 bits (0 to F) and lower 4 bits (0 to F), and stores conversion designation information of characters (characters) to be generated by the character generator 112, respectively. For example, if the bit data is “41”, the character “A” is designated for conversion, and if the bit data is “B1”, the character “A” is designated for conversion.
[0043]
This JIS8 code conversion table 113 can originally specify 16 (upper 4 bits) × 16 (lower 4 bits) = 256 characters. However, in the IP paging system, “80” to “9F” are used when creating a transmission message. ”,“ E0 ”to“ FF ”, 64 conversion designation areas are instructed to be converted into so-called“ shift JIS ”codes in which 2-byte data of JIS X 0208 (Kanji code table) is replaced with data. Therefore, the 34 conversion specification areas “00” to “2F”, “7F”, and “A0” are undefined. Therefore, these 98 areas are not used in the IP paging system.
[0044]
Therefore, in the IP paging system, only 158 conversion designation areas “20” to “7E” and “A1” to “DF” excluding the above areas are valid in the JIS8 code conversion table 113. Yes.
[0045]
Therefore, in this paging receiver, 128 conversion designation areas “20” to “6E” and “B1” to “DF” in the 158 conversion designation areas are assigned as image data to the image pattern. Shall be used.
[0046]
The shift JIS area table 115 is assumed to be a table having 64 conversion designation areas “80” to “9F” and “E0” to “FF” in the table described with reference to FIG.
[0047]
The 8-bit / dot pattern conversion table 114 is for converting 8-bit data as image data into 7-dot dot pattern data as shown in FIG. 10, and the above-described “80” to “9F”, “E0”. Corresponding to the 64 conversion designated area bit data of “FF” to “FF”, a dot pattern of 7 dots of each dot “1” “0” is generated.
[0048]
That is, the white dot portion shown as a 7-dot pattern indicates “0” (off) in the bit data, and the black dot portion indicates “1” (on) in the bit data.
[0049]
For example, when “20” (0010 0000) is specified in the JIS8 code, it is converted into a 7-dot dot pattern of 7 bits (0000000) and used as part of image data displayed by the display driver 6. The
[0050]
As shown in FIG. 11, the free word table 116 is a conversion table for creating a free word message by combining two digits of dial data “1” to “0”. For example, dial data “23” is transmitted. It is possible to display hiragana “ku”.
[0051]
The transmission data memory 12 sequentially inputs and stores data to be transmitted.
[0052]
When the message is received by the individual call service, the notification driver 13 drives the LED 14 to blink according to the preset notification content, and performs a sound by the speaker 15.
[0053]
The transmission buffer 16 sequentially stores data (numerical data, etc.) that can be converted into a DTMF (Dual Tone Multi Frequency) signal based on the transmission data created by the CPU 4 and sends the data to the D / A converter 27. The D / A converter 17 converts the data into an analog signal, converts it into a tone signal (DTMF signal), amplifies it by the amplifier 18 and outputs it to the speaker 19 to obtain two preset audible frequencies. A DTMF signal composed of a combination of signals is output continuously.
[0054]
The connector 20 is for capturing image data to be attached to the message at the time of transmitting the message. For example, by connecting to a personal computer or the like prepared by a service provider, the connector 20 captures image data for a fee or free of charge. Data can be stored in the data storage area IMGD.
[0055]
The infrared transmitter / receiver 21 performs infrared communication with other electronic devices in accordance with, for example, IrDA (Infrared Data Association) rules, and captures an image in the same manner as the connector 20.
[0056]
Next, the operation of the above embodiment will be described.
[0057]
FIG. 12 to FIG. 14 show the contents of the operation processing in the message transmission mode for creating and transmitting a message, which is an item in the menu with the menu screen initially displayed (step S01). By repeatedly executing the process of detecting that the creation of a new message is selected (step S02), and detecting the selection of the reading of a message that has already been created (step S51), Wait for these detections.
[0058]
If it is determined in step S02 that a selection operation for creating a new message has been detected, the process of actually inputting the new message is sequentially executed (step S03), and the message input is terminated. It waits for an operation to be detected (step S04).
[0059]
If it is determined in step S51 that a selection operation for reading a message that has already been created has been detected, the transmission message is selected from the individual call message memory area PMD in the RAM 10, read, and edited if necessary. Are sequentially executed (step S52), and the system waits until an operation for ending the process is detected (step S53).
[0060]
If it is determined in step S04 that an operation for ending the message input has been detected, or if it is determined that an operation for ending the processing on the message read in step S53 has been detected, then the information providing service for the message Whether or not an image is attached in correspondence with the address data, that is, in the stored contents of the ID-ROM 9 in FIG. 2, the frame number '87' or the frame in which “1” is set in the corresponding image flag F1 It is determined whether or not the transmission is based on the address data corresponding to the number “103” (step S05).
[0061]
If it is determined that an image is attached, a guide message for prompting selection of whether to attach image data to the created message is displayed on the display unit 7 (step S06). It is determined whether or not an instruction input for attaching is made (step S07).
[0062]
If it is determined that an instruction for attaching an image has been input, then referring to the image data management memory area IMM of the RAM 10 shown in FIG. 7 above, whether or not a plurality of image data is stored, that is, image data It is determined whether or not it is necessary to select (step S08).
[0063]
When a plurality of image data is not stored in the image data management memory area IMM and only one image data is stored and set, there is no room for selection. Although selection processing of image data is omitted, if it is determined that a plurality of image data is stored and set, a bitmap image obtained by simplifying the image data stored and set in the image data management memory area IMM is used. An instruction input for selecting an image is detected while a guide message prompting selection of which image to attach is displayed on the display unit 7 together with the image data by reading all of them and displaying them sequentially on the display unit 7 (step S09). Is repeatedly executed (step S10), and the process proceeds to the next when the detection is made.
[0064]
That is, when the selection of the image data is completed, it is then determined whether or not “1” is set in the copy prohibition flag F3 on the image data management memory area IMM corresponding to the selected image data (step S11).
[0065]
Here, when “1” is set in the copy prohibition flag F3, it is prohibited to copy the image data and send it attached to the created message. After displaying a guide message indicating that it cannot be performed on the display unit 7 (step S34), the process returns to the process of determining whether or not to attach the image data from step S05.
[0066]
If it is determined in step S11 that “1” is not set in the copy prohibition flag F3, the copy flag F4 on the image data management memory area IMM corresponding to the selected image data is then set to “ It is determined whether 1 ″ is set (step S12).
[0067]
Here, when “1” is set in the copy flag F4, it is prohibited to copy the image data as it is and send it attached to the created message. After adding a character pattern based on the user name in the user information memory area UD shown in FIG. 4 to the image data, the image data is decomposed into 7-dot units and converted into JIS8 codes, and the created message At the same time, it is set in the transmission data memory 12 (step S33).
[0068]
FIG. 15 shows that when a bitmap image stored in association with the image management address “001” in the image data management memory area IMM is selected as attached image data, the image file name “HYAKA.BMP” is used. Illustrated is vertical 56 × horizontal 90 dot image data itself read from the image data storage area IMGD. Here, the entire image is divided into vertical 4 × horizontal 9 blocks, and a television image indicated by an arrow on the right side of the figure. It is assumed that each block is processed in the order of raster scan.
[0069]
FIG. 16 exemplifies the dot pattern of the block divided into 14 × 10 dots. Here, the contents of the dot pattern of the block “PICT2” shown in FIG. 15 are shown.
[0070]
Such a dot pattern is further divided into 7 dots in the order of raster scan in a television image, so that the block “PICT2” has a dot array of <1> to <20> as shown in FIG. Referring to the 8-bit / dot pattern conversion table 114 of the ROM 11 shown in FIG. 10 above, the dot pattern of each dot row can be converted into a JIS8 code row as shown in FIG. it can.
[0071]
Therefore, such a string of JIS8 codes is set in the transmission data memory 12 together with the created message.
[0072]
If “1” is not set in the copy flag F4 of the image data selected in the above step S12, the image data can be copied as it is and attached to the created message for transmission. Since it is permitted, the selected image data is directly decomposed into units of 7 dots, converted into JIS8 code, and set in the transmission data memory 12 together with the created message (step S13).
[0073]
Thus, when the setting of the data to be transmitted in step S33 or S13 to the transmission data memory 12 is completed, the guide message prompting the instruction to specify the transmission destination is displayed on the display unit 7 in the next state. (Step S14), it is detected that a destination is newly input, or is detected that a telephone number already stored in the telephone directory data memory area TD of the RAM 10 is selected as a destination. Wait (steps S15 and S28).
[0074]
If it is determined in step S15 that it is detected that a destination is newly input, a guide message that prompts the user to input data to the telephone directory data memory area TD including at least the individual call number and the paging type is displayed on the display unit 7. (Step S16) After that, while sequentially receiving input operations from the key input unit 8 (Step S17), the process of waiting for detection of completion of input (Step S18) is repeated.
[0075]
If it is determined in step S18 that the end of input has been detected, the content of the flag F2 indicating whether or not image data can be received corresponding to the paging type is set in the corresponding position in the telephone directory data memory area TD. A setting is input (step S19).
[0076]
If it is determined in step S28 that the telephone number already stored in the telephone directory data memory area TD is selected as the destination, the name registered in the telephone directory data memory area TD is entered. While being displayed as a list on the display unit 7 (step S29), it waits for detection that any one of them is selected as a transmission destination (step S30).
[0077]
When it is determined that selection of the transmission destination has been made, the column of the paging type flag F2 is referred to according to the contents of the telephone directory data memory area TD of the selected transmission destination (step S31).
[0078]
Accordingly, it is determined whether the content of the paging type flag F2 set in step S19 or the content of the paging type flag F2 referred to in step S31 is “1” or “0” (step S20).
[0079]
Here, when the content of the paging type flag F2 is “0”, since a message with image data attached cannot be transmitted to the transmission destination, a guide message indicating that the image cannot be transmitted is displayed. After being displayed on the display unit 7 (step S32), the process returns to the process from step S14 to specify the transmission destination again.
[0080]
If it is determined in step S20 that the content of the paging type flag F2 is “1”, image data can be attached to the transmission destination and transmitted, so that the previously set message In addition to the image data, the individual call number of the transmission destination is set in the transmission data memory 12 (step S21).
[0081]
Thereafter, while the speaker 19 is in contact with the handset of the nearest telephone set, while waiting for an instruction to actually perform transmission (step S22), it is determined whether or not the instruction has been detected (step S23). The process is repeated.
[0082]
When it is determined that it has been detected, first, the individual call number of the transmission destination set in the transmission data memory 12 is converted into a digital DTMF signal and transferred to the transmission buffer 16, and the D / A converter 17 Then, the individual call number of the transmission destination by the DTMF signal is sent from the speaker 19 through the amplifier 18 (step S24).
[0083]
Subsequently, while waiting for an instruction to execute transmission again (step S25), the process of determining whether or not the instruction has been detected (step S26) is repeated.
[0084]
When it is determined that the message has been detected, the message data set in the transmission data memory 12 and the image data attached thereto are converted into a digital DTMF signal and transferred to the transmission buffer 16, and the D / D Message data and image data based on the DTMF signal are transmitted from the speaker 19 via the A conversion unit 17 and the amplifier 18 (step S27), and the processing in the message transmission mode of FIGS.
[0085]
FIG. 19 shows an example of the data structure of the message part in the message field output from the speaker 19 at this time. Here, it is assumed that the frame is transmitted in two frames depending on the capacity of the attached image data.
[0086]
That is, in the message field of the first frame shown in FIG. 19 (1), in addition to the message data, an image identification code indicating that image data is attached and its image property data are arranged, and then the actual image is displayed. A division code (1) indicating that there is a part of the data and the divided image data in another subsequent frame is arranged.
[0087]
The image property data includes the image file name and information for prohibiting copying, and is included in the first frame here, but is included in other frames after the second frame. Also good.
[0088]
Further, in the message field of the second frame shown in FIG. 19 (2), the actual image data remaining after the image identification code indicating that the image data is attached, and the image divided in other subsequent frames as well. When there is data, a division code (2) is provided, or when the transmission of image data is terminated in the second message field, an end code is provided.
[0089]
Note that the size and capacity of the image data attached to the message data and transmitted by the paging receiver are variable as illustrated in the configuration of the image data management memory area IMM in FIG. 19 except that the smallest one is divided into two frames of message fields as shown in FIG. 19, and the larger one is sequentially increased in the number of division codes as necessary to increase the number of frames. It shall be divided and transmitted.
[0090]
In step S05, no image is attached corresponding to the address data for the information providing service of the message, and in the stored contents of the ID-ROM 9 in FIG. 2, “1” is set in the corresponding image flag F1. If it is determined that the transmission is not based on the address data corresponding to the frame number “87” or the frame number “103”, or if it is determined in step S07 that an instruction for attaching an image has not been input. The image data attached to the message is not transmitted, and only a newly input or selected message is set in the transmission data memory 12 (step S35), and then an instruction for designating the transmission destination on the display unit 7 With the guide message prompting the input being displayed (step S36), the transmission destination is set. It is repeatedly waited for detection of input to a rule or detection of selection of a telephone number already stored in the telephone directory data memory area TD of the RAM 10 as a transmission destination (steps S37 and S42). .
[0091]
If it is determined in step S37 that a new transmission destination has been detected, a guide message for prompting the user to input data into the telephone directory data memory area TD including at least the individual call number and the paging type is displayed on the display unit 7. (Step S38) Thereafter, while receiving input operations from the key input unit 8 in sequence (Step S39), the process of waiting for detection of the end of input (Step S40) is repeated.
[0092]
If it is determined in step S40 that the end of input has been detected, the content of the flag F2 indicating whether or not image data can be received corresponding to the paging type is set in the corresponding position in the telephone directory data memory area TD. A setting is input (step S41).
[0093]
If it is determined in step S42 that it has been detected that the telephone number already stored in the telephone directory data memory area TD is selected as the destination, the name registered in the telephone directory data memory area TD is entered. While being displayed as a list on the display unit 7 (step S43), it waits for detection that any one of them is selected as a transmission destination (step S44).
[0094]
Thus, after setting the paging type flag F2 in step S41 or determining that the transmission destination selection has been detected in step S44, the individual call number of the transmission destination is transmitted in addition to the previously set message. Set in the data memory 12 and wait for an instruction to actually perform transmission with the speaker 19 in contact with the transmitter of the nearest telephone (step S45), and determine whether or not the instruction has been detected (Step S46) is repeated.
[0095]
When it is determined that it has been detected, first, the individual call number of the transmission destination set in the transmission data memory 12 is converted into a digital DTMF signal and transferred to the transmission buffer 16, and the D / A converter 17 Then, the individual call number of the transmission destination by the DTMF signal is sent from the speaker 19 through the amplifier 18 (step S47).
[0096]
Subsequently, while waiting for an instruction to execute transmission again (step S48), the process of determining whether or not the instruction has been detected (step S49) is repeated.
[0097]
When it is determined that the message has been detected, the message data set in the transmission data memory 12 is converted into a digital DTMF signal and transferred to the transmission buffer 16, via the D / A converter 17 and the amplifier 18. Then, message data based on the DTMF signal is sent from the speaker 19 (step S50), and the processing in the message transmission mode shown in FIGS.
[0098]
Next, processing contents when an incoming call is detected by a paging receiver similar to the paging receiver having the circuit configuration shown in FIG. 1 will be described with reference to FIG.
[0099]
This figure shows the processing executed when an incoming call that matches the frame, address data, and vector data registered in the ID-ROM 9 of the own device is detected. At first, one frame is received first. The data processing circuit 5 fetches the data (step S60). First, it is determined whether an image identification code is set in the message field (step S61).
[0100]
Here, if it is determined that no image identification code is set and no image data is attached to the message field detected as an incoming call, it is then determined whether or not there is message data (step S65).
[0101]
If it is determined that there is message data, the notification driver 13 and the speaker 15 are notified by the notification driver 13 when the incoming call is detected, and at the same time, the received message data is displayed on the display unit 7 and displayed. (Step S66), and the process at the time of incoming is finished.
[0102]
If it is determined in step S65 that there is no message data, the notification driver 13 performs the incoming notification using the notification driver 13 and the speaker 15 as it is when the incoming call is detected (step S72). This completes the process for incoming calls.
[0103]
If it is determined in step S61 that an image identification code is set in the message field of the incoming frame, the content of the divided code attached to the end of the message field is (1). (2) It is determined whether the end code replaces the transition or division code, or whether a code similar to the division code and the end code is not set (step S62).
[0104]
If it is determined in step S62 that the division code attached to the end of the message field is (1), the frame is a frame located at the beginning of a series of image data. Since part of the image data is arranged and image property data may be arranged, a new image management address is set in the image data management memory area IMM, and the image property data is arranged. If it has been stored, after storing the copy prohibition flag F3, copy flag F4, file name, etc. based on the property data (step S63), the corresponding file name is also set in the image data storage area IMGD. The image data is stored (step S64).
[0105]
Thereafter, the process proceeds to step S65, where it is determined whether there is message data together with image data in the message field. If it is determined that there is message data, the process proceeds to step S66, and a notification accompanying the detection of an incoming call is made. At the same time that the driver 13 performs the incoming call notification using the notification driver 13 and the speaker 15, the received message data is displayed and output on the display unit 7. On the other hand, if it is determined that there is no message data, the process directly goes to step S72. Only the incoming call notification using the notification driver 13 and the speaker 15 by the notification driver 13 accompanying the detection of the incoming call is executed.
[0106]
Further, it is determined whether or not there is message data in step S62 (step S65).
[0107]
If it is determined that there is message data, the notification driver 13 and the speaker 15 are notified by the notification driver 13 when the incoming call is detected, and at the same time, the received message data is displayed on the display unit 7 and displayed. (Step S66), and the process at the time of incoming is finished.
[0108]
If it is determined in step S62 that the end of the message field is a divided code or end code after (2), the frame is a frame positioned at the second or later of a series of image data, and the image identification is performed. Since part of the image data is arranged after the code and there is a possibility that the image property data is arranged, the image property data is arranged at the image management address set in the image data management memory area IMM. If it has been stored, after storing the copy prohibition flag F3, the copy flag F4, the file name, etc. based on the property data (step S67), the image data of the corresponding file name set in the image data storage area IMGD Is added and stored (step S68), and then the message field Division code or an end code to the end to determine whether it is set (step S69).
[0109]
If it is determined that a split code or end code has been set, the process ends as it is and the next incoming call is entered, but if it is determined that something other than the split code or end code has been set. Alternatively, if it is determined in step S62 that neither the division code (1), the division code (2) or after, or the end code is arranged at the end of the message field, the message field in the received frame is specified. Whether or not it is based on the information providing service is determined by the attached specific identification code or the like (step S70), and only when it is determined that it is the specific information providing service, the ID-ROM 9 together with the file name is determined. Is written to additionally set a new image management address (step S71). To end the process.
[0110]
21 and 22 exemplify the display state of message data with image data attached as described above. As shown in FIG. 21, in the state where the content of the message data received on the display unit 7 in the process of step S66 is “There is a bargain tomorrow”, other data is displayed at the bottom of the display unit 7. For example, a symbol a is displayed.
[0111]
By operating, for example, a downward cursor key of the key input unit 8 corresponding to this display, the image data attached to the message data is displayed on the display unit 7 as shown in FIG. In this case, the sender name b shown as “Takeshi Ogawa” in the figure indicates that this image data has been copied by the sender.
[0112]
In the above embodiment, since the copying of the image data is completely prohibited and the information representing the sender is inserted into the image and the transmission itself is permitted, it is restricted in two stages. It is possible to realize setting of restrictions on copying for each image data as necessary.
[0113]
