Abstract

PURPOSE: To prevent erroneous operations, etc., by making it possible to obtain various input key operation signals repeatedly or in another place or at another time.
CONSTITUTION: A binary parallel signal is obtained by input circuit 2 according to operations of switches 11W136 and is converted to a series transfer signal by shift register 3 and is supplied to modulation circuit 4 to modulate the modulation wave supplied from timing circuit 5. This modulation signal is recorded on a tape recorder, and the reproducing output of this tape recorder is supplied to input terminal 7. Demoduation circuit 8 separates the tape recorder output into the series transfer signal and the synchronizing signal, and the synchronizing signal is supplied to timing circuit 10, and the series transfer signal is supplied to shift register 9. Shift register 9 converts the series transfer signal to a parallel signal and holds it in latch 11 and converts it to the original output signal through buffer 12.
