In the figure, 1 is a coordinate detection device consisting of two detection plates 2 and 3 facing each other, 4 is a liquid crystal dot matrix display device arranged below the coordinate detection device 1, and 5 is an analog-to-digital conversion circuit 6 and an arithmetic unit. 7, etc., controls the blinking of the liquid crystal dots on the display device 4. on the other hand,
The detection plate 2 consists of a coordinate detection section 8 which is made of a transparent material such as polyester having low resistance and coated with a metal oxide or an elemental metal as a resistor by vapor deposition or the like, and electrodes 9 provided at both ends of the coordinate detection section 8. It becomes more. In addition, detection plates are provided at both ends of the coordinate detection section 10, which is made of a transparent material and coated with a metal oxide or a metal element as a resistor by vapor deposition or the like, and at both ends of the coordinate detection section 1o to interpolate the electrodes 9. These coordinate detecting parts 8 and 10 each consist of an electrode 9
The evaporation surfaces are placed opposite each other through insulating spacers 12 in which small transparent insulating pieces having uniform resistance in the longitudinal direction of 11 are regularly arranged. A pair of conducting wires 13 and 14 are connected to the electrodes 9 and 11, respectively, and the other end is connected to an input switching device 15 of the control device 6.

れ演算装置７に入力される。To explain the operation in the above configuration, first, the input switching device 16 applies the voltage V of the drive power source 16 to the electrode 11 of the detection plate 3 through the conductor 14. At this time, the coordinate detection unit 1
0 has a constant potential in the vertical direction of the electrode 11 depending on its position. When the coordinate detection section 8 is pressed for input using the writing instrument 17, the coordinate detection sections 8 and 1o come into contact with each other at the pressed input point.
The potential corresponding to the input point on 0 is detected by the electrode 9 of the detection plate 2. This potential is input to the input switching device 15 of the control device 5 through the conducting wire 13, and then converted into a digital signal by the analog-to-digital conversion circuit 6 as a potential difference with a reference voltage and input to the arithmetic unit 7.
ここで演算装置７はこのデジタル信号を１次元の入力位

検出部１ｏおよび８を透過して見ることができる。The input switching device 15 is then switched, and the voltage V is now applied to the electrode 9 through the conductor 13. The rest of the process is similar to that described above, so that the potential corresponding to the input point on the coordinate detection section 8 is detected on the electrode 11 of the detection plate 3. This potential is also input to the arithmetic unit 7 as a digital signal by an operation similar to that of the control device 6 described above, and is input to the arithmetic unit 7 as a digital signal.
Together with the dimensional input position information, this information is processed as two-dimensional input position information, and the blinking of the liquid crystal dots on the display device 4 is controlled. The blinking liquid crystal dots on the display device 4 can be seen through the transparent coordinate detection sections 1o and 8.

Furthermore, by changing the arithmetic processing method of the arithmetic device Y, characters and figures can be easily deleted. Therefore, the user can input characters and figures while viewing them at hand, just as if they were writing on paper with a pencil, and there are fewer erroneous inputs.
