PURPOSE:To simplify the switching operation for time correction, by generating two signals from one switch input signal via a timer circuit, and correcting independent counting circuits respectively. CONSTITUTION:When a signal is inputted to a switch input terminal 7, chattering is absorbed by a chattering preventing circuit 1. A monopulse signal is outputted from a first wave shaping circuit 3. A counter 6 for a 10min position performs +1 counting. If the signal is continued to be inputted to the switch input terminal 7, a timer 2 receives the signal of the output 8 of the chattering preventing circuit 1 and begins the operation. After the time length set in the timer, a second wave shaping circuit 4 outputs the signal of the monopulse waveform, and a counter 5 for a 1min position performes +1 counting. |
