PURPOSE:To certainly achieve the purpose of an alarm, by mounting an apparatus capable of arbitrarily setting the number of times of effective snoozes and making it possible to temporarily stop an alarm when the content of a count circuit for counting said number of times is coincided with the set number of times. CONSTITUTION:An alarm switch S1 is opened to bring a snooze circuit SN to a non-operable state while analogue switches AS3, AS4 are opened to push a sound stopping switch S2 desired number of times and an alarm apparatus AL is allowed to generate confirmation sound. When the switch S1 is closed at predetermined time, alarm sound is emitted from the apparatus AL to open the switch AS2 and the switches AS3, AS4 are closed to bring the circuit SN to an operation preparatory state. Next, when the circuit SN is set to stop the alarm and this operation is repeated for the predetermined number of times, a switch AS1 holds a closed state. By this method, the circuit SN is made non-operative and the stopping of the alarm can be prevented. |
