[0036] First, a first embodiment of the present invention will be described. A first embodiment of the invention is a timepiece with a rotor and a wheel train, ie, an analog electronic timepiece. 1-4, in the first embodiment of the analog electronic timepiece of the present invention, the movement mechanism (mechanical part) 100 of the analog electronic timepiece has a chassis 102 constituting the movement mechanism. The reel 110 is installed in the reel guide hole of the chassis 102 and can rotate. A dial 104 (shown in phantom in FIG. 2 ) is mounted in the movement mechanism 100 . The motion mechanism 100 has a switching spring 166 for determining the axial position of the spool 110 .
[0037] On the "surface side" of the movement mechanism 100 are arranged the following various parts: battery 120, circuit module 116, hour motor 210, hour display wheel train 220, minute motor 240, minute display wheel train 250, second motor 270, second Show gear train 280 etc. The chassi...

[0077] Next, a second embodiment of the present invention will be described. A second embodiment of the invention is a mechanical timepiece with a mainspring and a train of wheels. Referring to FIGS. 5-7 , in a mechanical timepiece, a movement mechanism (mechanical part) 300 of the mechanical timepiece has a chassis 302 constituting a base plate of the movement mechanism. The reel 310 is assembled in the reel guide hole 302a of the chassis 302, and is rotatable. A dial 304 (shown in phantom in FIG. 26 ) is mounted on the kinematic mechanism 300 . Usually, among both sides of the chassis, the side with the dial is called the "inner side" of the movement mechanism, and the side opposite to the side with the dial is called the "surface side". The gear train installed on the "surface side" of the kinematic mechanism is called the "surface side gear train", while the gear train installed on the "inside" of the kinematic mechanism is called the "inner gear train".

Abstract
The invention relates to a timepiece which has a resin substrate, rotors, and wheel trains, and relates to a wheel train apparatus which has a resin substrate, bearing members, gear wheel, and the like. The invention is constituted by a timepiece comprising; a gear wheel, and a substrate which supports a shaft of a rotor and / or a shaft of the gear wheel, the substrate being formed from a filled resin. Alternatively the invention is constituted by a wheel train apparatus comprising: a gear wheel; a substrate which supports one shaft section of the gear wheel, and a bridge which rotatably supports an other shaft section of the gear wheel, the substrate and the bridge being formed from a filled resin.
Description
technical field [0001] The present invention relates to timepieces having resin-made substrates, rotors, gears, etc., for example, analog electronic timepieces, mechanical timepieces. In addition, the present invention also relates to a gear train device having a resin-made base plate, a bearing member, a gear, and the like. Background technique [0002] Conventionally, clocks having a wheel train driven by a motor, for example, an analog electronic timepiece, have driven a rotor constituted by a stepping motor to rotate the wheel train. For example, a gear train composed of gears such as the fifth wheel, the fourth wheel, the third wheel, and the minute wheel. The rotor pinion (in the rotor, the part except the rotor magnet, the same below), the fifth wheel, the third wheel, etc. can be made of metal, or can be made of so-called engineering plastics such as polyoxymethylene. [0003] In addition, conventionally there is a gear train device that rotates by the power of a m...
