Abstract

PURPOSE: To make parallel connection of respective touch plates possible by constituting the touch plates by parallel-connected tape switches and pulse generators which generate echo pulses after a fixed delay time in response with the timing pulses.
CONSTITUTION: The touch plates T1'... of respective courses are constituted by respectively parallel-connected tape switches TS-1', TS-2'... and pulse generators D1, D2,... and in response to the timing pulses of the specified periods from a printing timer 8 by respectively different time constant circuits, the generators D1, D2... generate echo pulses after the different time within the said periods and send them to the timer 8 when the switch part is ON. By the echo pulses of the generation time differing by each course, the respective record plates T1', T2'... are parallel- connected to one address line ABL, by which the arrival time is determined and the installation and mounting of the touch plates are made easy. If the timing pulse periods are shortened, the accuracy and resolution of the recording time will improve.
