Claims (1)

[Scope of Claim for Utility Model Registration] A clock mechanism that displays the time on a time display and outputs an alarm control signal when the time set in the time display comes, and a clock mechanism that detects infrared rays corresponding to human body temperature. Pyroelectric infrared sensor,
an alarm control means for outputting an alarm control signal from the clock mechanism section only while a predetermined infrared detection output from the pyroelectric infrared sensor is obtained; The alarm clock is equipped with a motor as the clock mechanism, the motor rotates the hands on the time display section to display the time, and the motor causes the pyroelectric An alarm clock characterized by driving a tipper mechanism for an infrared sensor.
