Abstract

PURPOSE:To detect a human body stably over the range of 360 deg. by securing a human body sensor to the clock body, and rotating a reflector constantly in one direction to enter the infrared rays from a human body into the human body sensor, thereby avoiding the failure due to contact of the movable part and a connection wire. CONSTITUTION:A reflector 8 is rotated constantly in one direction through a drive section 10 to direct the infrared rays from a human body toward a human body sensor 2 secured to a clock body 4. A detection circuit 12 detects a human body over the range of 360 deg. based on an output signal from the sensor 2 and delivers a detection signal. When the surroundings is bright, an AND gate 18 is opened by a signal from a brightness sensor 16 and a detection signal is applied to the input 10 of a simulation sound IC 26. Consequently, the IC 26 produces a note of bird which is delivered from a speaker 30. When the surroundings is dark, an AND gate 22 is opened and a detection signal is applied to the input 11 of the IC 26 thus producing the chirps of a cricket. Since the connection wires and the like are not wired at the rotary part, failure due to disconnection or twisting of the connection wires can be eliminated.

In the conventional timepiece described above, when the sensor in the pendulum is connected to a device or the like outside the pendulum, the rotation support shaft is wired. For this reason, the movable parts such as the rotary support shaft and the wiring come into contact with each other, causing a disconnection,
There was a high possibility that defects such as a pendulum stop would occur.

Further, if the pendulum is rotated 360 degrees or continuously rotated in one direction, the connecting line is twisted, so that the connecting line cannot be used, and wiring processing is performed with a more complicated connecting structure. Was needed.

The present invention has been made in view of the above problems, and an object thereof is to detect a human body capable of detecting a human body at 360 degrees around a timepiece without a movable part being influenced by wiring and having a simple structure. It is to provide a timepiece with a mechanism.
