Problems solved by technology

[0044] However, when the rotor rotation is unstable, the time until the IC drive is also deviated, even if the preset value is corrected, the time cannot be accurately aligned, and there is a problem that it is difficult to perform high-precision time synchronization.
[0045] In addition, even if the rotation force caused by the drive rod is constant, and the flexibility of the drive rod must be managed with high precision, such management can achieve the accuracy that can be fully utilized in general purposes, but there is a problem that it is difficult to obtain higher accuracy

Abstract

A timing device with a starting device that applies mechanical rotational force to the rotor of an electromagnetic converter such as a generator to start it. A starting spring (60) is provided, and an engaging portion (63) capable of engaging with the No. 6 pinion (11a) in the gear train connected to the generator is provided. When the crown is pulled out, the return lever (70) is activated to energize the starter spring and engages with the No. 6 pinion, and then when the crown is pushed in, the urging force of the starter spring is released. The starting spring returns to the original position under the action of its elastic force, and at this time, the mechanical turning force of the pinion is given. This turning force can give the rotor (12) stable turning force because it can only be set by the elastic force of the starting spring.

Description

technical field [0001] The present invention relates to a watch type timing device with a starter device for an electromagnetic converter in a generator or a motor. Background technique [0002] In Japanese Patent Application Laid-Open No. 8-5758, a known electronically controlled mechanical watch is described. The mechanical energy when the mainspring is released is converted into electrical energy by means of a generator. The current value in the watch can accurately drive the pointer fixed on the wheel train to accurately indicate the time. [0003] At this time, once the power of the generator is supplied to the filter capacitor, the rotation control device is driven by the power from the capacitor. However, since the AC electromotive force synchronized with the rotation period of the generator is usually input to the capacitor, it is possible to use IC or crystal oscillator. It is not necessary to maintain the electric power for the operation of the swing control devic...
