The kanji conversion command is transmitted to the portable information terminal main unit 13 through the terminal. After transmitting the kanji conversion command to the portable information terminal body 13, there are some kanji candidates in the portable information terminal body 13,
When the pop-up menu 17 is displayed, the switch 3 is pressed once more, and a kanji selection command is transmitted from the pen 6 to the portable information terminal body 13 via the communication cable 15.

When the kanji to be selected is determined, the switch 3 is pressed twice at a high speed (so-called double-click), and a confirmation command is transmitted from the pen 6 to the portable information terminal body 13 via the communication cable 15. The portable information terminal body 1 that has received the confirmation instruction
3 determines the kanji and ends the kanji conversion work.

Energy for driving the control unit 2 and the communication means inside the pen 6 is supplied from the battery 5.
The control unit 2 and the communication cable 15 are operated only when the switch 3 is pressed in order to extend the life of the battery 5.

FIG. 5 is a block diagram of a pen-input type portable information terminal according to the present invention, showing another example. In FIG.

When the kanji to be selected is determined, the kanji determination command is transmitted via the communication cable 15 or the transmission / reception units 16a and 16b by double-clicking the switch 3 of the pen 6. The portable information terminal body 13 that has completed the kanji determination processing transmits a determination end notification to the pen 6 via the communication cable 15 or the transmission / reception units 16a and 16b, and the pen shifts to a standby state. The reason why the ID authentication is always performed in the flow of the kanji conversion process is that when a nearby person uses the same pen input type portable information terminal, the pen input type portable information terminal held by the user and the other person are different. This is to prevent a malfunction due to signal cross-talk with the pen input portable information terminal held by the user.

[0017]

Since the pen is provided with a switch for conversion, selection and confirmation, a smooth kanji conversion operation can be performed.

By providing a conversion, selection, and confirmation switch on the pen, the conversion and confirmation pad is not required on the portable information terminal main body, and the portion directly touched by the tip of the pen can be reduced. As a result, the failure rate due to scratches and the like can be reduced.

By performing the kanji conversion operation according to the present invention wirelessly, it is possible to obtain a pen-input portable information terminal that is cableless and has good operability.

Since ID authentication is performed between the pen and the portable information terminal main body, malfunction due to signal crosstalk between the pen and the similar device being used by another person can be prevented.
