Abstract
PURPOSE: To enable the setting of correct alarm time with simple constitution, by making coincidence between the alarm time and present time electronically through the storage of the count time difference and controlling the rotation of the step motor for display.
CONSTITUTION: When alarm time is set with the operation set 12, the time difference counter 13 counts and stores the time difference between the set time and present time via the control circuit 11, and when the count value is zero, the alarm tone is casted from the alarm unit 16 with electronic coincidence. On the other hand, the display difference counter 15 counts and stores the difference between the display time and present time with the pointer 6 via the circuit 11, and the magnitude of the memory content is discriminated at the discriminating circuit 17 in response to the display selective operation of the set 12, the step motor 4 is turned forward or reverse by the count difference stored in the counter 13 to perform the display selection of the present time and alarm set time. The alarm time can accurately be set in the unit of second with a simple constitution not requiring coincidence circuit and easy and sure display selection.
