The operation by the dedicated pen 30 is monitored (step S1). When the “PC link” button is operated by the dedicated pen 30, a check signal for setting a link relationship with the desk PC 1 is transmitted by the infrared communication device 25. The infrared signal is transmitted to the desk PC 1 (step S2), and the desk PC 1 responds to the check signal.
Check if there is a response signal from.

If there is no response from the desk PC1, it is impossible to set a link relationship with the desk PC1, and thus the PC link processing is immediately terminated, and the desk PC1 is terminated.
If there is a response from the PC 1, the PC link signal is transmitted to the desk PC 1 by infrared rays through the infrared communication device 25 (step S4), the link state with the desk PC 1 is established, and the menu displayed on the display unit 21 is displayed. A “mail transfer” button is displayed on the screen as shown in FIG.

If the mail transmission request signal has not been received, the process proceeds to step S10. The mail communication program stored in the storage device 23a is started, and FIG.
When the mail window screen is displayed on the display unit 21 (step S7) as shown in (5), the "destination", "subject" and the text of the mail are input, and the file and data to be transmitted are received from the desk PC 1 (step S8). 5), the file and data to be transmitted are attached to the mail text as shown in FIG. 5D (step S9), and the wireless communication protocol is executed by the wireless communication interface 24, and the wireless base station and the public network To transmit a wireless mail to an external communication service center via the Internet.

If the CPU 23 does not receive a mail transmission request signal from the desk PC 1 in the process of step S6, the CPU 23 proceeds to the process of step S10, and presses the “mail transfer” button displayed on the menu screen of the display unit 21. Is operated by the dedicated pen 30. If the "mail transfer" button is not operated, the process returns to the step S6, and if the "mail transfer" button is operated, the mail communication program stored in the internal memory 23a is started, and shown in FIG. Thus, the mail window screen is displayed on the display unit 21 (step S11), and the mail list of the mail received from the communication service center addressed to the user of the portable information terminal device 20 and stored in the internal memory 23a is further displayed. Then, as shown in FIG. 7B, the mail to be transferred is specified (step S12).

Then, the CPU 23 reads out the specified mail from the internal memory 23a, converts the text of the mail included in the mail into text (step S13),
The image data is converted into a bitmap (step S1).
4) The text data and the bitmap image data are transmitted to the desk PC 1 by the infrared communication device 5 by infrared transmission (step S15), and are displayed on the display device 6 of the desk PC 1 and displayed on the reception screen as shown in FIG. , And display the text and image of the specified mail.

Further, the CPU 23 checks whether or not there is an attached file in the specified mail (step S1).
6) If there is no attached file, the process returns to the step S6. If there is an attached file, the attached file is transmitted to the desk PC 1 by infrared rays through the infrared communication device 5 (step S17), and the display device of the desk PC 1 is sent. After the attachment file icon is also displayed on the reception screen shown in FIG. 7D as shown in FIG. 7D, the process returns to step S6.

A link state is established between the two, and a “mail transmission” button is displayed on the display screen of the display device 6 as shown in FIG. 5E or FIG. 7C (step P2).

Next, the CPU 2 executes the portable information terminal 2
In step P3, it is confirmed whether or not the forwarded mail transmitted by infrared in the PC link processing has been received (step P3).
If the forwarded mail is not received, the process proceeds to step P7. If the forwarded mail is received, the received text data, bitmap image data, and attached file icon are displayed on the display screen of the display device 6 as shown in FIG. The display is performed as shown in d) (steps P4 to P6).

If no transfer mail is received in step P3, the CPU 2 checks whether or not the "mail transmission" icon displayed on the display screen in step P7 has been operated. If the "send mail" icon is not operated, the process returns to the step P3 and the "send mail"
When the icon is operated, a file or data to be attached to the mail is specified (step P8).

When the file or the data is specified, the CPU 2 causes the infrared communication device 5 to transmit a mail transmission request signal to the portable information terminal device 20 by infrared rays (step P9). The mail transmission process described in the link process is started (see FIGS. 5C and 5D), and the specific file or data is transmitted to the portable information terminal device 20 by the infrared communication device 5 via infrared rays (step P10). ), And returns to the process of step P3.
