Abstract

PURPOSE: To detect the time with high accuracy by controlling the second contact of the alarm setting device in a closable manner by a counting wheel 16.
CONSTITUTION: An alarm setting wheel is engaged with a hour wheel and rotates in synchronism therewith. Three minutes before the alarm set time, an unlocking wheel 20 and engagement grooves 22a and 22b of the alarm setting wheel, receiving the compressive force of a lift spring 10a, coincide with each other. The unlocking wheel shaft 12 comes into abutment with the lift spring 10a to make the first contact device in a closed state. When the counting set time is reached, the minute cam 16a of the minute counting wheel 16 integrally formed with the third wheel 40 comes into abutment with a ratch lever 32a of the minute control level 32 to move the lever 32 in the clockwise direction. Then, the operating member 32b of the lever 32 is separated from a movable contact plate 10c, and the movable contact plate 10c is rotated to be restored to a position contacting the movable contact plate 10b, and the closing operation of the second contact device is obtained to actuate a sound announcing device.
