DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a timepiece, and particularly to a timepiece that can function as both a pendulum clock and a total swing clock.

In recent years, electronically driven watches using O crystal oscillators, etc.
Pendulum clocks, whose pendulum is driven by the driving force of a movement case, have been widely put into practical use as decorations.

This type of pendulum clock has a movement case and a swinging rod supported in a swingable manner, and usually has a structure in which a V-groove of the swinging rod is supported by a knife of the movement case. A pendulum is locked at the F end of the swing rod body, and the swing rod body and pendulum are oscillated by an electromagnetic driving force between a magnet fixed to the swing rod body and a drive coil provided in the movement case. Can sustain exercise.

Further, in recent years, the total swing time d[, in which the movement case and the pendulum swing relative to the pendulum fulcrum, has been widely put into practical use for decorative purposes.

In this type of total swing clock, the movement case and pendulum are supported so as to be able to swing freely about the pendulum fulcrum of the fixed support, and in normal cases, the knife of the V-groove VC movement mechanism of the fixed support is supported. The structure consists of The oscillating motion of the movement case and pendulum can be maintained by the electromagnetic driving force between the drive coil provided on the movement case and the magnet on the plate between the magnet receiver and the fixed support.

The problem with the general swing clock is that it has a separate structure and cannot be used as both a pendulum clock and a general swing clock.

The present invention has been made to solve the above-mentioned conventional problems, and the main purpose of the present invention is to use the same movement case and electromagnetic drive plate in common, so that it can be used as both a pendulum clock and a general swing clock. The aim is to provide a watch that can be used.

In order to achieve the above object, the present invention provides a support part provided at one end of the movement case and whose support end serves as a pendulum fulcrum, and a drive part provided at the other end opposite to the @1 support part of the movement case. An electromagnetic drive plate having a coil or a magnet, a receiving portion that engages with the support portion at one end, and a magnet or drive coil that is magnetically coupled to the *T period drive coil or magnet at the other end; '5rami, when the pendulum swings I
When using it as an IT, the movement case is fixed through the clock mechanism case, and the amount of electromagnetic drive is determined by using the plate as a plate for the swing receiver. When the pendulum is oscillated and used as a total swing clock, the electromagnetic drive amount is fixed by fixing the plate, fixing the pendulum to a clock mechanism case that houses and fixing the movement case, and attaching the movement case to one electromagnetic body plate. It is characterized in that it is supported so as to be able to swing freely, so that it can function as both a pendulum clock and a calm clock.
