Abstract
PURPOSE: To enable the time intervals at which an alarm is made depending upon the duration of the preset time intervals to be automatically adjusted by providing a circuit of setting the alarm time by the set contents of a set counter.
CONSTITUTION: While an unlock switch 1 is held turned ON, the input of the alarm time intervals from a switch 3 may be inputted to a set counter 5 and when the unlock switch 1 is turned OFF, the contents of a set counter 5 are retransferred to a down counter 6 and at the same time the down counter 6 is made to perform subtraction operation by the 1 Hz signal from terminal 8, whereby a second counter 18 is operated. The length of the alarm time intervals having been set in the set counter 5 is detected by passing the output from the second counter 18 to AND gates 20, 22 24, thus an alarm 27 may be sounded at desired time intervals.
