Abstract
PURPOSE: To simplify the circuit by impressing the up-down counting signals, which are generated when a maual switch is turned on, and carry signals upon a counter which is supplied with clocks as all times.
CONSTITUTION: When one of UP and DOWN switches is turned on, UP or DOWN signals are generated so that an FF 1 is set through overflow preventing gate 4 or 5. And, counters 21 and 22, which are supplied with the clocks of an oscillator 3 at all times, are brought into UP or DOWN mode. At the same time, the carry signals from the logic circuit 6, which is supplied with the UP and DOWN signals through the gates 4 and 5, are impressed so that the counters 21 and 22 effect the UP or DOWN count of the clocks of the oscillator 3. According to such construction, the clocks are impressed no indirectly through the gate circuit but directly to a counter so that the circuit can be so cimplified as to be free from any miscount due to the influences from the impedance of the connecting wire
