Abstract

PURPOSE:To enable preset operation at one section, by the addition or subtraction of the counter with one preset switch only. CONSTITUTION:The output of a monostable multivibrator 4 is delivered to an inverter 5. The output of the inverter 5 and that of a pulse train generating circuit 8 are respectively input to two input terminals of the AND gate circuit 6. During the operation of the multivibrator 4, the circuit 6 is closed and the pulse train produced from the pulse train generating circuit 8 is not delivered to the next stage, and when the multivibrator 4 is finished for the operation, then the circuit 6 is set and the pulse train is delivered to the next stage. The output from the circuit 6 is input to the UP-terminal of the counter 7 and the counter performs addition one by one every time when one pulse of the pulse train is input. This addition is kept while the preset switch 1 is depressed.
