Abstract

PURPOSE: To improve the operativeness and speed, by utilizing the variation of resistance value due to pressure of a sensible pressure conductive sheet, and also making it possible to separately detect the position of a pen in the X directon and the position of a pen in the Y direction.
CONSTITUTION: An X conductor and a Y conductor are provided through the insulating plate 24, and the input board is formed by providing sensible pressure conductive sheets 20, 22 on each conductor, and also an electrode plate 21. An output of the counter 25 is input to the decoder 26 and drives the X conductor in order. In case the input board is pushed by a pen, when the X conductor existing at that position has been driven, voltage is applied to the point A through the electrode plate 21. The level detector 30 detects this voltage, sets FF31, and the counter is stopped due to a drop of the reset output. Value of the counter 25 is set to the X register 34 by an output of the sampling pulse generator, and it is taken out as an X coordinate code. A Y co-ordinate is also taken out in the same way.
