PURPOSE:To make snoozing time coincide with an elapsed time indicated on a time indicator, by making a snoozing counter count pulses produced by a switch mechanism which opens or closes in response to minutely change of time indication of clock movement. CONSTITUTION:This is so designed that opening or closing of a minute switch 107' is directly conveyed to a snoozing circuit 114', and at the same time, it is also conveyed to an alarm input circuit 109' and an alarm auto-cut circuit 112' through a signal processing circuit 116, and then, opening or closing of a time switch 108 is conveyed to the alarm input circuit 109' directly. And, the swit 107' is to be opened hile a motor is operating for 6 seconds every minute, and the switch 107' is not to be opened only when clock time is just about to coincide with the reference time. Pulses produced by opening of the switch 107' are counted by a built-in counter of the circuit 114' and the snoozing time is decided. This allows counting pulses to be given to the circuit 114' in accordance with feeding of clock movement, and therefore, the snoozing time coincides with the elapsed time indicated on a time indicator. |
