Japanese Patent Application No. 61-21970 (JP-A-63-70326)
Japanese Patent Application No. 62-208293 (JP-A-6-208293).
The description is omitted because it is well known in Japanese Patent Application Laid-Open No. 4-53223). Also, during the coordinate detection period, the electromagnetic wave generated from the loop coil closest to the resonance circuit 15 of the electronic information pen 10 ′ of the tablet 30 for a predetermined duration and with a constant cycle is the same as the resonance wave of the electronic information pen 10 ′. Generates a large induced voltage, and furthermore, diodes 18a, 18b
, And passes through the low-pass filters 18d and 18e. At this time, the output of the low-pass filter 18f does not exceed the threshold value of the comparator 18i and no start signal is output, so that the D flip-flop 19a is not set. , Counter 19b, shift register 19c, latch 1
Neither 9d nor the selector 19e operate.

In the information transmission period, when an electromagnetic wave (a) continuous from the loop coil closest to the resonance circuit 15 of the electronic information pen 10 ′ of the tablet 30 is generated for the predetermined period or more, the electromagnetic wave (a) is transmitted to the electronic information pen 10 ′. 'Resonance circuit 15
Generates a similar induced voltage (b), but this induced voltage
(B) causes the comparator 18i to generate a start signal (h) via the diode 18c and the low-pass filter 18f (g).
The start signal (h) sets the D flip-flop 19a.
(I) The counter 19b starts counting and sets the shift register 19c and the selector 19e to an operable state.

Thereafter, the electronic information pen 1 of the tablet 30
According to the information to be transmitted from the loop coil closest to the resonance circuit 15 of 0 'to the electronic information pen 10' side, the electromagnetic wave (A) generated for a certain period sufficiently shorter than the predetermined period or for a certain period sufficiently shorter than the predetermined period is Electronic information pen 1
A similar induced voltage (b) is generated in the resonance circuit 15 of 0 ',
These cause the comparator 18g to generate a clock (d) through a diode 18a and a low-pass filter 18d (c), and generate a clock (d) at the diode 18b and a low-pass filter 18e (e).
To the comparator 18h through the information bit, an 8-bit information comprising an information bit of code "1" and an information bit of code "0"
(F) is generated. Here, the information bit of code "1" is an induced voltage corresponding to an electromagnetic wave (a) generated for a certain period sufficiently longer than a certain time, and
The information bit of code "0" is an induced voltage corresponding to an electromagnetic wave (a) generated in a certain time.

The clock (d) increments the counter 19b and stores 8-bit information in the shift register 19c.
(F) are sequentially read. The counter 19b is a clock
When (d) is counted by 8 bits, the D flip-flop 19a
Is reset, and the data of the shift register 19c, that is, 8-bit information (f) is latched by the latch 19d. The contents of the latch 19d are periodically read into the microprocessor 22 as described above, and processed according to the contents as described above.

On the other hand, during the counting of the clock (d) as described above, the selector 19 e
Switch 16b according to the information consisting of a binary code of bits
Is turned on / off to change the resonance frequency of the resonance circuit 15.

Here, the induced voltage (b) is equal to that of the tablet 3.
A reception signal (induction voltage) (not shown) is generated in the loop coil closest to the resonance circuit 15 of the electronic information pen 10 'of 0, but a reception signal is generated based on the induction voltage (b) based on the electromagnetic wave continuous for the predetermined period or more. At this point, the D flip-flop 19a is in the reset state and the selector 19e
Is inoperable, so switch 22b is off,
That is, the capacitor 16a is not connected to the resonance circuit 15. Therefore, the output value of the A / D conversion circuit 43 based on the received signal at this time becomes a reference value in detecting the phase difference.

The processing unit 45 is connected to the A / D conversion circuit 4 at this time.
3 is compared with the output value of the received signal obtained after conversion by the A / D conversion circuit 43, using the output value of No. 3 as a reference value.
If they are the same, the switch 16b is turned off, that is, the code "0", and if they are different, the switch 16b is turned on, that is, the code "1", and the information from the electronic information pen 10 'is received.

The processing device 45 sends the received information, that is, personal information or operation information, to the terminal device main body 70 'together with the coordinate value of the designated position. And information transmission is repeated.
