Abstract
An electronic cash register comprises a control switch for allowing and prohibiting printing and issuance of a receipt according to input data introduced by input keys and a delay circuit for deferring operation of the control switch for a predetermined period of time of the actuation of the control switch. The delay circuit provides accurate control for the allowance and prohibition of receipt printing and issuing operation independently of actuation timings when the control switch is energized, thereby preventing random printing and publication of the receipt dependently on the timed relationship of actuation of the control switch.
