Abstract
PURPOSE: To prevent error input by extracting the ON-OFF state of each contact corresponding to several adjacent coordinates of a pressure-sensitive data input part and then by outputting normal input data only when one of them is in the ON state.
CONSTITUTION: Counter 23a drives decoder 21 by the clock of clock oscillator 24, and counter 23b also drives multiplexer MX22 by using a high-order 5-bit clock. Corresponding to one signal from counter 23b, MX22 outputs signals of three continuous Y lines from pressure-sensitive data input part 20. Decoder 21 drives X lines of input part 20, one by one, according to the signal of counter 23a. Three outputs of MX22 are supplied to 3-bit shift registers SR25WSR27. All bit outputs of SR25W SR26 except 26B2 are inputted to AND gate 29 via an inverter and the output of SR26B2 is inputted to gate 29 as it is. Therefore, when only one contact of input part 20 is made, data is outputted from gate 29.
