Filed: 1983-04-15
Abstract: PURPOSE:To facilitate and secure the setting of an alarm time by selecting an alarm time setting mode for a specific timer period with a pulse switch on, and extending the timer period according to alarm time setting operation. CONSTITUTION:When the pulse switch 1 is pressed, a contact 2 is made to discharge a capacitor 21, which is held at a low level for a specific time period until the capacitor 21 is recharged with the output of a comparing circuit 19 which forms a timer.

Then, the output of a comparing circuit 9 is inverted to a high level as far as an alarm time is set by turning the switch 1, and the TR14 is turned on to discharge the capacitor 21, extending the timer period. Thus, an alarm time is set easily and securely only with one hand.
