The electronic mail received and transferred by the telephone 1 is displayed and the electronic mail input by the tablet input unit 6 is transferred to the telephone 1.
[0045]
Next, the operation of the above embodiment will be described.
FIG. 5 illustrates a storage state when the users of the plurality of display terminals 3, 3,... Respectively register the recognition codes in a predetermined area of the memory 16 of the telephone 1 prior to receiving the electronic mail.
[0046]
For example, the character string is input by handwriting using the display terminal 3 used by Mr. “Taro”, and the display terminal 3 is attached to the telephone 1 as shown in FIG. The registration setting information is stored in both the memory 16 of the telephone 1 and the memory 23 of the display terminal 3 as shown in FIG. 5 by operating the pointing command of the registration setting command displayed on the display unit 3a with the stylus pen 5. Will come to be.
[0047]
Similarly, in order to register “Hanako” as the ID code “B” on the display terminal 3 used by “Hanako”, the ID code and the address of the electronic mail are “B: hanako @... In addition, in order to register “Kenji” as the ID code “C” on the display terminal 3 used by “Kenji”, the ID code and the electronic mail address are “C: kenji @…” Set each as follows.
[0048]
By performing the registration as described above, with respect to the electronic mail received by the telephone 1 thereafter, one of the ID lamp units 4 is the transfer lamp 2b depending on the personal name attached to the head of the address. When the transfer key 2b is operated after attaching the display terminal 3 corresponding to the recognition code, the electronic mail received after identifying the display terminal 3 is transferred and stored in the display terminal 3. Become.
[0049]
In the above embodiment, the mail address is acquired for each user in the group (for example, family) (contracted with the provider), and the electronic mail individually stored in the server is associated with the group. Although it was set as the system which transmits to a telephone number, it is not restricted to this, For example, a mail address is comprised with "group + member" (For example, "taro (member) + yamada (group) @ ..."), The server may store electronic mails related to the group in a lump and send the electronic mails to the telephone numbers corresponding to the group in a lump. In this case, on the mail phone side, the electronic mail is sorted by the members of the address.
[0050]
FIG. 6 shows the personal name attached to the head of the address of the received electronic mail and the lamp blinking in the ID lamp section 4 of the telephone 1, the display terminal 3 used by each individual, And an identification code / user's personal name relationship. For example, when an electronic mail with an address “taro @...” Is received, lamp A blinks and is transferred to a terminal having “ID: A”. .
[0051]
Next, FIG. 7 shows an operation when the telephone 1 actually receives an electronic mail sent via the public line network NW. This figure mainly shows the contents of processing performed by the control unit 12 of the telephone 1, and initially, electronic mail (shown as "E-mail" in the figure) is received from the public network NW via the communication control unit 11. (Step B1), and when it is determined that it has been received, the received electronic mail is stored in a predetermined area of the memory 16 (step B2).
[0052]
Next, the destination is confirmed from the personal name attached to the head of the address in the received electronic mail, the lamp of the corresponding ID lamp unit 4 is driven to blink (step B3), and the incoming call which is also the transfer key 2b The lamp is driven to blink to notify that there is an incoming electronic mail (step B4). This series of processes is completed, and the electronic mail reception standby state at step B1 is resumed.
[0053]
Next, referring to FIG. 8, the electronic mail received by attaching the corresponding display terminal 3 to the telephone 1 in the state in which the incoming call lamp is blinkingly driven by the transfer key 2 b to notify the incoming call state is sent to the display terminal 3. The operation when transferring is described.
[0054]
That is, the telephone 1 waits for the operation of the transfer key 2b which also functions as an incoming call lamp in the notification state (step C1). When it is determined that the transfer key 2b is operated, the transmitter / receiver unit 1a is operated. Then, in order to confirm the display terminal 3 that should be attached, a request signal for transmitting the recognition code to the display terminal 3 is transmitted (step C2).
[0055]
The display terminal 3 attached to the telephone 1 waits for this request signal to be received by the transmitter / receiver unit 3b (step D1). When it is determined that the request signal has been received, the ID code of its own device is sent via the transmitter / receiver unit 3b. (Step D2).
[0056]
The telephone 1 receives the ID code sent from the display terminal 3 (step C3), and then searches the memory 16 based on the received ID code to determine whether there is a corresponding electronic mail. (Step C4).
[0057]
If it is determined that there is no corresponding electronic mail, this process is terminated at that time and the process returns to the standby state for the transfer key 2b operation in step C1, but there is an electronic mail corresponding to the attached display terminal 3. If determined, the electronic mail is then read from the memory 16, and the read electronic mail is transferred from the light transmitting / receiving unit 1a to the light transmitting / receiving unit 3b of the display terminal 3 by the optical communication control unit 17 (step C5). ).
[0058]
The display terminal 3 determines whether or not an electronic mail is received from the telephone 1 after transmitting the ID code to the telephone 1 in the above step D2 (step D3), and when there is no electronic mail. Returns to the processing from step D1 again assuming that the electronic mail addressed to itself is not stored in the telephone 1, but if it is determined that the electronic mail is received, the received electronic mail is then stored in the memory 23. In step D4, a completion signal is transmitted to the telephone 1 in order to complete the reception of the electronic mail (step D5). This series of processes is completed, and the operation returns to step D1.
[0059]
On the other hand, when the telephone set 1 determines that the transfer is completed after waiting for the reception of the completion signal from the display terminal 3 (step C6), the transferred electronic mail is deleted from the memory 16 (step C7). It is determined whether or not the electronic mail with the personal name of the same ID code as that of the display terminal 3 that has transmitted the electronic mail is left in the memory 16 (step C8).
[0060]
Here, when it is determined that the electronic mail still remains in the memory 16, the transfer of the electronic mail to the display terminal 3 has not been completed. Repeat the process from the confirmation process.
[0061]
If it is determined in step C8 that there is no electronic mail remaining in the memory 16, the transfer of the electronic mail to the display terminal 3 is completely completed, and the ID lamp unit 4 is attached. The lamp corresponding to the display terminal 3 is turned off (step C9), and it is determined whether or not there is still an electronic mail for the display terminal 3 that has another recognition code and is not currently mounted in the memory 16 (step C10). .
[0062]
Here, when it is determined that there is still an electronic mail to be transferred to another display terminal 3 in the memory 16, the display state of the incoming call lamp and the ID lamp unit 4 as the transfer key 2 b is temporarily kept as it is. This process ends and the process returns to the process from step C1 again.
[0063]
If it is determined in step C10 that the electronic mail to be transferred to another display terminal 3 is not already stored in the memory 16, no ID lamp unit 4 has already been blinked at that time. Therefore, the incoming call lamp which is the transfer key 2b is also extinguished, and this process is completed.
[0064]
In the display terminal 3 to which the electronic mail is transferred, a symbol indicating that the received electronic mail is stored in the memory 23 is displayed in a part of the display unit 3a, and the symbol position is pointed by the stylus pen 5. When operated, the electronic mail stored in the memory 23 is read and displayed on the display unit 3a.
[0065]
As described above, in a state where the reception of the electronic mail is informed by the incoming call button, any one of the plurality of display terminals 3, 3,. When the electronic mail corresponding to the recognition code of the attached display terminal 3 is received and stored by operating 2b, the electronic mail is automatically transferred to the display terminal 3, so this transfer completed The display terminal 3 can be detached from the telephone 1 again, and the contents can be confirmed by the display unit 3a of the display terminal 3 at a place different from the place where the telephone 1 is installed.
[0066]
In this case, whether or not the electronic mail received and stored by the telephone 1 is addressed to the user can be readily understood by the display state on the ID lamp unit 4, and the electronic mail other than the addressed to the user is used by the user. Since the display terminal 3 cannot transfer the information, the confidentiality of the electronic mail can be reliably maintained.
[0067]
In the above embodiment, a plurality of display terminals 3, 3,... Have been described as being selectively attached to one telephone 1, but a configuration for only one display terminal 3 is also conceivable. In this case, the configuration relating to the ID lamp unit 4 and the recognition code and the control associated therewith can be simplified.
[0068]
Further, the display terminal 3 is not dedicated for mounting on the telephone 1, and may be mounted as one function of an information device having a display unit such as an electronic notebook, personal computer, or portable information terminal. . In this case, the above function is not fixedly provided, and a program for realizing the function may be read from a recording medium such as a memory card, a floppy disk, a CD-ROM, or a DVD-ROM.
[0069]

[0084]
Here, the control unit 54 controls the entire apparatus based on a predetermined protocol stored in the ROM 55.
The ROM 55 stores a control program in the control unit 54. The RAM 56 temporarily stores data handled under the control of the control unit 54, and in particular secures a predetermined capacity area for storing received electronic mail and electronic mail to be transmitted.
[0085]
Next, the operation of the above embodiment will be described.
FIG. 12 shows both the PHS master unit 31 and the PHS slave unit 32A (to 32D) when the PHS master unit 31 receives the electronic mail and transfers it to the PHS slave unit 32A (to 32D) corresponding to the destination of the electronic mail. This shows the processing contents.
[0086]
First, the PHS base unit 31 waits for an incoming call via the public network NW (step E1), and when it is determined that there is an incoming call, it determines whether the incoming call is an electronic mail (step E2). .
[0087]
If the incoming call is not an electronic mail, the incoming call is for a telephone call and the process proceeds to call processing. However, if the incoming call is an electronic mail, the PHS slave unit 32A corresponding to the destination is sent. Only one of .about.32D is called (step E3).
[0088]
Then, depending on whether or not there is a response to this call from the PHS slave unit 32A (to 32D), the PHS slave unit 32A (to 32D) may be within the communication range of the PHS master unit 31 and transfer electronic mail. If it is determined whether or not there is a response, then the received electronic mail is sequentially transferred to the PHS slave unit 32A (to 32D) using the own device as a relay device (step E5). ).
[0089]
Thereafter, it is determined whether or not a completion signal has been sent from the PHS slave unit 32A (to 32D) (step E6), and if it has not been sent, the relay operation at step E5 is continued.
[0090]
When it is determined that a completion signal has been sent from the PHS slave unit 32A (to 32D), a series of electronic mail reception and transfer processes are terminated, and the process returns to step E1 again to wait for the next incoming call. .
[0091]
On the other hand, the PHS slave unit 32A (to 32D) waits for a call from the PHS master unit 31 (step F1), and when it determines that there is a call, it sends a signal for response to the PHS master unit 31. At the same time, it is determined whether or not the call is for reception of electronic mail based on the content of the control code portion in the received signal from the PHS base unit 31 (step F2).
[0092]
Here, if it is not the reception of the electronic mail, the reception is for a telephone call, so the process proceeds to the telephone call processing. The electronic mail in the received signal transferred as a repeater is sequentially stored in a preset area of the RAM 56 (step F3), and the completion signal is transmitted to the PHS main unit 31 when the reception and storage of the electronic mail are completed. (Step F4), the series of processes is completed as described above, and the operation returns to Step F1 again.
[0093]
In the PHS cordless handset 32A (up to 32D) that has received the electronic mail, a symbol indicating that the received electronic mail is stored in the RAM 56 is displayed in a part of the display unit 33d, and a key input unit corresponding to the display. For example, when a specific key such as “mail read” of 33e is operated, the electronic mail stored in the RAM 56 is read and displayed on the display unit 33d.
[0094]
If the PHS master unit 31 determines that the response to the call is not received from the PHS slave unit 32A (-32D) in step E4, the PHS slave unit 32A (-32D) communicates with the PHS master unit 31. Since it is out of service area and electronic mail cannot be transferred, only one of the incoming lamp 31d and ID lamp unit 31e corresponding to the destination of the electronic mail is driven to blink, and there is only reception of the electronic mail. (Step E7), and the process returns to step E1 again.
[0095]
In this case, the user of the PHS cordless handset 32A (-32D) who later notices the notification by the incoming call lamp 31d and the ID lamp unit 31e recognizes that the electronic mail has been received to the own machine, and again the PHS. By accessing the electronic mail server via the base unit 31 and the public line network NW, the received electronic mail can be reliably fetched.
[0096]
As described above, when an electronic mail is received by the PHS master unit 31, if the PHS slave unit 32A (up to 32D) that is the destination of the electronic mail is within the communication range of the PHS master unit 31, the PHS master unit 31 relays the electronic mail received and transfers it to the corresponding PHS cordless handset 32A (-32D), and if there is no destination PHS cordless handset 32A (-32D) within the communication range, Since only the destination is notified, a memory for storing and storing the received electronic mail in the PHS master unit 31 is not required, and the configuration can be simplified.
[0097]
In addition, since the PHS slaves 32A to 32D that are normally used by individuals are also used as display terminals for receiving electronic mail, a dedicated display terminal is not required, and the burden on the user can be reduced.
[0098]
In addition, although the said embodiment demonstrated using the structure by the main | base station and the subunit | mobile_unit of PHS, this invention is not limited to this, An analog / digital cordless telephone for home use, or an analog / digital Needless to say, this can also be realized by a mobile phone and a parent device that has registered it.
In addition, the present invention can be variously modified and implemented without departing from the scope of the invention.
[0099]
【The invention's effect】
