Abstract

PURPOSE:To achieve reduction in cost by simplifying composition of a circuit, by making an alarm auto counter and a snooze counter count signals for intermittent operation of a motor and decide alarm-sounding time and snoozing time. CONSTITUTION:An alarm auto cut circuit 112' and a snooze control circuit 114', which are respectively provided inside with quinary counters, count up-and-down of signals for intermittent operation of a (1/60)Hz motor sent from a frequency- dividing circuit 105. And, if a minute switch 107 and an hour switch 108 are closed during duty period of the signal for intermittent operation of the motor, an alarm input circuit 109 latches a high-level output status in response to it, and immediately after this, an alarm signal is issued from an alarm control circuit 110. Further, if a snooze switch 115 is ON at the time when an alarm is sounding, an output prohibiting signal is given from the circuit 114' to the circuit 110, and when the counter of the circuit 114' counted 5 pieces, the circuit 110 is given a snooze cancelling signal and emits an alarm operating signal.
