To achieve the above object, in the present invention, as shown in FIG. 1, a frequency setting unit 2, a gate 3, a frequency analyzing unit 4, a transmitting unit 5, and a receiving unit 6 are provided in an electronic pen 1. To provide. The frequency setting unit 2 outputs a specific frequency f ₂ indicating an identification number ID unique to an individual who uses the electronic pen 1. The frequency analysis unit 4 detects the output signal f ₁ output from the tablet.

[0006]

Now, when the operator touches a tablet (not shown) with the electronic pen 1, the radio wave of the frequency f ₁ output from the tablet is received by the receiving section 6, which is analyzed by the frequency analyzing section 4 to generate f ₁ Then, the gate 3 is turned on.

As a result, the signal of frequency f ₂ indicating the operator's ID is transmitted from the frequency setting unit 2 to the transmitting unit 5 through the gate 3 and the radio wave of f ₂ is transmitted. Recognizing that this f ₂ is detected by the tablet and is f ₂ , and that it is a person authorized to use this tablet, the power is turned on, the computer is started, the coordinates touched by the electronic pen 1 are detected, The input instruction is judged.

At this time, if the frequency output from the electronic pen 1 is not f ₂ but another frequency, it is determined that the tablet is not the ID of the authorized user and the computer is not started. Further, if the application name is displayed in the specific frame portion of this tablet, by simply touching it with the electronic pen 1, f ₂ is detected by the tablet, it is recognized as a licensed person, and the computer system starts up. The OS runs. Moreover, since the application program is selected and activated according to the coordinates touched by the electronic pen 1, even a user unfamiliar with such a tablet device can easily activate the application program.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. FIG. 2 is a block diagram of an embodiment of the present invention.
[Fig. 6] is an operation explanatory view of the present invention.

In FIG. 2, the same symbols as in FIG. 1 indicate the same parts, 10 is a tablet, 11 is a receiving unit, 12 is a receiving frequency detecting unit, 13 is a discriminating unit, 14 is a registering unit, and 15 is a system activation control unit. , 16 are control units.

The frequency setting unit 2 of the electronic pen 1 sets the frequency indicating the ID of the individual who uses the electronic pen 1. Then, in order to selectively set the frequency, dip switches SW1, SW2 ... SWn are provided, and for example, when the SW1 is turned on, the frequency f ₂ is output.

Although the tablet 10 is a coordinate input means for a position designated by the electronic pen 1, it will be described here as including a computer body, a liquid crystal display device on which the tablet is present, and the like.

The receiver 11 receives the radio wave transmitted from the electronic pen 1 and sends it to the reception frequency detector 12. The reception frequency detection unit 12 detects the frequency of the radio wave received by the reception unit 11.

The discriminating unit 13 determines whether or not the frequency of the received radio wave is an ID indicating a person authorized to use the tablet 10.
The determination is made by referring to 4. The frequency of the electronic pen 1 permitted to use the tablet 10 is entered in the registration unit 14. This frequency may be limited to one, or a plurality of frequencies may be set.

The system activation unit 15 activates the system of the computer including the tablet 10 and operates the OS. The control unit 16 comprehensively controls the tablet 10.

Next, the operation of FIG. 2 will be described. When the tablet 10 is touched by the electronic pen 1, the reception unit 6 of the electronic pen 1 receives the radio wave transmitted from the tablet 10 and transmits the radio wave to the frequency analysis unit 4. The frequency analysis unit 4 recognizes that the reception frequency is f ₁ and turns on the gate 3. Since this time the frequency setting unit 2 has a frequency set to f _2, the frequency signal f ₂ is transmitted to the transmission unit 5 via the gate 3, radio waves of the frequency f ₂ is outputted from the transmitting unit 5. This radio wave is received by the receiving unit 11 of the tablet 10, and the following processing is performed by the tablet 1 as described in FIG.
It is done at zero.

The receiving section 11 receives the radio wave transmitted from the electronic pen 1. The reception frequency detection unit 12 detects the frequency of the reception radio wave and notifies the discrimination unit 13 of this. For example, it notifies that the received frequency is f ₂ . The determination unit 13 checks whether or not this frequency is the frequency registered in the registration unit 14 as an ID indicating the authorized user of the tablet 10, that is, the specified frequency. If the frequency is not the specified frequency, the system will not start and the OS will not operate.

If the frequency is the specified frequency, the discriminating section 13 activates the system starting section 15 to start up the system, and
To work. As a result, the control unit 16 of the tablet 10 detects the coordinates of the position touched by the electronic pen 1.
