The oscillating coil 12 includes a detection coil serving as a sensor for detecting the oscillating magnet 5e and a drive coil serving as an electromagnet provided coaxially. The drive circuit unit (not shown) generates an induced voltage in the detection coil when the swinging magnet 5e passes near the detection coil, and causes a current to flow through the drive coil based on the induced voltage. A swing circuit of the pendulum 5 can be maintained by applying a suction repulsive force to the swing magnet 5e in accordance with the swing of the pendulum 5 by a drive circuit unit (not shown). Therefore, the magnet 5d provided at the lower end of the swing ball 5c swings right and left.

Next, the light emitting units 6, 8, and 10 will be described. The three light emitting units 6, 8, and 10 have the same configuration and are arranged on the frame 2. Light emitting units 6, 8, 10
Are arranged on the frame 2 so as not to overlap each other when viewed from the front of the frame along the trajectory of the magnet 5d.
That is, the light emitting unit 6 is arranged on the left side of the trajectory of the swing of the magnet 5d, the light emitting unit 8 is arranged substantially at the center of the trajectory, and the light emitting unit 10 is arranged on the right side of the trajectory. Each of the light emitting units 6, 8, and 10 is a flat circuit board 6a, 8a, 10a.
And magnetic circuits 6b mounted on the circuit board,

It is composed of The three light emitting units 6, 8, 10
Is a rib (not shown) provided on the frame 2 and the circuit board 6.
a, 8a, and 10a are fixed to the frame 2 by engaging with each other.

Since the three magnetic circuits 6b, 8b and 10b have the same configuration, only the magnetic circuit 8b will be described.
As shown in FIG. 6, the magnetic circuit 8b includes a yoke 8d and a coil member 8e wound in the axial direction of the yoke 8d. The magnetic circuit 8b includes a circuit board 8a

They are electrically connected by the pattern provided above. Thus, when the pendulum magnet 5d approaches the yoke 8d, a magnetic flux is generated inside the yoke 8d, a voltage is induced in the coil member 8e, and a current is supplied to the light emitting diode 8c to emit light instantaneously.

Next, the operation of the pendulum timepiece having such a configuration will be described with reference to FIGS. As shown in FIG. 2, when the pendulum 5 is located substantially at the center of the frame 2 (when the magnet 5d passes over the magnetic circuit 8c), the magnetic circuit 8
A magnetic flux is generated inside the yoke b, and a voltage is induced in the coil member wound around the yoke, so that a current is supplied to the light emitting diode 8c electrically connected to the coil member, and the light emitting diode 8c It emits light.

As described above, when the pendulum 5 swings, the three light emitting portions 6, 8, and 10 sequentially emit light so as to match the swing of the pendulum 2, so that a pendulum clock with a rich taste can be obtained. Also,
Since a control circuit for sequentially emitting light from the plurality of light emitting units 6, 8, and 10 in accordance with the swing of the pendulum 5 is not required, it can be easily manufactured. Further, since the light emitting units 6, 8, and 10 are arranged on the frame, it is possible to prevent a cord for supplying electric power to the light emitting unit from being routed, and it is possible to greatly ease restrictions on mounting.

Next, a second embodiment will be described with reference to FIGS. For convenience of description, FIGS. 7 to 9 omit the frame.

b and 10b are installed in the frame so that the light emitting diodes emit light when the light emitting diode and the smoke plate 5g overlap when viewed from the front side of the frame. Thus, when the light emitting diode and the through hole overlap in a front view, the light emitting diode emits light instantaneously. That is, when the pendulum 5 is located to the left of the frame 2, a red glowing ball appears on the surface of the smoke plate 5g, and when the pendulum 2 is located substantially at the center of the frame, it appears on the surface of the smoke plate 5g. When a yellow glowing ball appears and the pendulum 5 is located to the right of the frame 2, a blue glowing ball appears on the surface of the smoke plate 5g, so that the pendulum swings as in the first embodiment. A plurality of light-emitting portions are sequentially lit so as to match, and a pendulum clock with a rich taste can be obtained.
