ABSTRACT:
An alarm device of clocks having snoozing function in which, when a set time is reached in clock mechanism, switching means for alarm sound source is actuated to be ON-state through an actuating lever by a set-time indexing wheel shifted on a shaft being rotated by the clock mechanism. The actuating lever disposed for transmitting the shifted motion of the indexing wheel to the switching means is pivotable respectively in a first plane including axial shifting directions of the wheel and in a second plane perpendicular to the first plane. Pivotal motion of the lever in the first plane followingthe shifted motion of the wheel on the set time causes the switching means to be switched ON, in which state a snoozing means manually operated moves the lever pivotally in the second plane to cause the switching means temporarily to be switched OFF and restrict the lever in this position for a fixed cyclic period after the set time. As long as the lever is in the pivotally moved position in the first plane, repetitive restrictions of the lever in the position moved in the second plane by the snoozing mechanism are also released in the same cycle of the fixed period to repetitively sound the alarm sound source.
