In the normal hand operation without the time adjustment of the hands, the rotor of the step motor is the driving source, and the driving torque is from the wheel train to the rotor pinion → 5th gear / 5th pinion → 4th gear / 4th pinion (second hand axis)
→ 3rd gear / 3rd kana → 2nd gear / 2nd kana (minute hand shaft)
→ Day reverse gear / Day reverse kana → Transmission is via the hour wheel (hour hand). On the other hand, the correction torque at the time of the correction of the hands is transmitted through the route of crown / makizuma → tsumi wheel → reverse gear → second pinion (minute hand correction), reverse wheel kana → hour wheel (hour hand correction).

て、輪列の中で通常3番カナと2番歯車の噛合いを外す
ことによって修正トルクが秒針とその先に伝わることを
阻止し、修正操作が円滑にできるようにしている。When the correction torque further acts on the speed-up gear train and the rotor, the correction torque becomes excessive due to the resistance, the correction speed decreases, the phase of the rotor magnetic pole shifts, and the timing of restarting is delayed. Therefore, the second hand only needs to be stopped at the time of correction, and it is not necessary to rotate and correct it. Normally, the correction torque is released by disengaging the third gear and the second gear in the wheel train. This prevents the second hand and the second hand from being transmitted so that corrective operations can be performed smoothly.

れている。A mechanism for disengaging the lower gear is provided with a lower bearing of a third wheel (a bearing closer to the pinion) on a lever mechanism, and this lever is rotated in conjunction with an operation of pulling a crown to lower the lower bearing. Away from the 4th axle (pointer axis). As a result, the third wheel is inclined, and while the meshing between the third gear and the fourth wheel is maintained, the third wheel is disconnected from the second wheel, and the correction torque is not transmitted to the second hand and the rotor. . The above basic configuration is also disclosed, for example, in Japanese Utility Model Laid-Open No. 58-71181.

When the crown is pulled during the correction of the hands, the leading end of the winding stem moves upward, the winding engaging portion also moves upward, and the main body 51 rotates slightly counterclockwise. When the crown is pushed in after the correction operation, it returns to the old position.

It is inserted into the fork of a switching lever (shown in another figure) having a third wheel lower bearing, which is turned at the time of correction to disengage and is restored when the correction is completed. The return torque for restoration is generated by the return spring portion 55 whose tip is engaged with the part 11 of the main plate and is slightly bent in advance. As described above, the reset lever is also a kind of multi-purpose part. The relationship with other mechanisms will be described more clearly later in the embodiments of the present invention.
