Abstract

PURPOSE: To make clear the operationability of the repetitive operation set, by enabling the set of repetitive operation only during timer operation.
CONSTITUTION: When the timer time is set to the memory counter 9 and the start switch 31 is operated, the pulse from the wave shape circuit 26 is fed via the OR circuit 10 and the timer counter 7 starts the time count and SR type FF12 is set with the output pulse of the circuit 26. Thus, until FF12 is reset with the agreement between the count time of the counter 7 and the set time of the counter 9, the AND gate 13 is closed with the set output of FF12. Accordingly, when the switch 32 is operated until the counter 7 starts count and the set timer reaches the time, the output pulse of the wave shape circuit 27 sets the repetitive operation SR type FF 15 via the gate 13 and the repetitive operation is set. As a result, the operation of the troublesome repetitive set is made simpler to prevent the occurrence of malfunction.
