Abstract

In the time detecting device of an alarm clock is provided with an hour gear wheel and an alarm gear wheel, each having an indication hand, engaging with a second hour gear wheel and a second alarm gear wheel respectively. An detecting cam plate is provided so as to be axially shiftable and continuously pushed and turned by the second hour gear wheel. A projection is formed on either the second alarm gear wheel or the detecting cam plate while a hole is formed on the other. When the respective phases of the projection and the hole coincide, the detecting cam plate is allowed to shift to actuate the alarm device.
