Abstract

PURPOSE: To simplify the driving line selection circuit by driving the electromagnetic type input unit via the output of each stage of the shift register.
CONSTITUTION: Counter 2'b counts clock pulse CP and generates address signal A to supply it to shift control code memory 2'c. With shift control code (b), shift right signal (c) and shift left signal (d) are generated. These signals are supplied in sequence to shift register 3'a connected to the driving line which detects the electromagnetic coupling to be converted into signals (e)W(h) which vary alternately with each stage output featuring the adjacent phases of output stages Q1, Q2, Q3... of register 3'a to which initial value 1000... are supplied. These stage outputs are supplied to driving lines l1Wln via the driving transistor.
