As shown in the figure, in order to keep the stop position of the second hand unchanged, one of the gear trains that drives the second hand is pressed against the tip of the train wheel setting lever to press the front end of the train wheel setting lever.
Is determined by the spring portion 103 of the actuating lever, and the train wheel setting lever does not have elasticity. The direction of the pushing force is in the direction of the central axis of the gear wheel. It was known how to make a tongue contact with.

Although it is determined by the elasticity and strain of the spring portion 103 of the operating lever, there is a limit to how thin and long the spring portion 103 of the operating lever can be made due to the limited space and processing capability of the watch parts. There is a drawback that the contact force between the gear and the gear is strong, and the tooth tip of the gear to be set is deformed when the second hand is repeatedly stopped. When the train wheel setting lever 104 comes into contact with the gear 107, the pressure contact portion 104d of the train wheel setting lever 104 with the gear wheel 107 moves to the third position.
It is almost impossible to make contact with multiple tooth tips at the same time, whether it is an arc shape as shown in the figure or a flat shape as shown in FIG.
In most cases, it contacts the tip of one tooth of the gear 107. In such a case, as one of the rare cases, one of the tooth tips may be subjected to the centripetal pressure contact, but in general, the pressure contact is displaced from the centripetal direction. As described above, the pressure contact portion 104d of the train wheel setting lever 104 is settled down while being supported by the two tooth tips of the gear. Therefore, train wheel setting lever 10
After the pressure contact portion 104d of 4 contacts the tooth tip of the gear 107, the gear 107
The movement of the gear until it is supported by the two tooth tips of is transmitted to the second hand, and when adjusting the time of the clock, the position of the second hand changes when the winding stem is operated, not only the appearance is not good, but also the train wheel setting lever 104 is pressed. Depending on the number of teeth of the gear 107 and the deceleration rate,
Move the rotor of the stepping motor to rotate it to a position with a polarity different from the stop position, and when adjusting the clock time,
Stop the second hand at the advanced or delayed position. When driving the stepping motor again, from the function of the stepping motor, if the second hand stops at the advanced position, the movement of the second hand is corrected and the time indicated is correct, but if it stops at the delayed position, the second hand does not move. There was a defect that it was delayed for 2 seconds and the hand was moved.
本発明では限られたスペースでも規正レバーと規正する
歯車の圧接力を緩和し，且つ秒針の停止位置が変化して

うにした。(Means for Solving the Problem) The present invention will be described in detail. As shown in FIG. 7 or FIG. 8, the direction of the pressure contact surface at which the train wheel setting lever for stopping the movement of the pointer and the gear are in pressure contact, and the train wheel setting lever The direction of the pushing force is different, and the train wheel setting lever is S-shaped or inverted S-shaped. The direction of the normal of the pressure contact surface where the train wheel setting lever and the gear are in pressure contact with the direction of the pushing force of the train wheel setting lever. Thus, the direction in which the gear to be trained is fed is set so that the S-shaped or inverted S-shaped compression direction of the train wheel setting lever substantially coincides with the perpendicular direction of the pressure contact surface.

とができる。(Operation) When the train wheel setting lever thus configured is pressed against the gear that stops the movement of the pointer, the direction of the normal line of the pressure contact surface where the train wheel setting lever and the gear are in contact is the direction in which the gear rotates, so Since the direction of the force applied to the gear moves in the direction of sending the gear and the train wheel setting lever is S-shaped or inverted S-shaped, the elastic portion can be lengthened, and when the pressure contact surface is pressed against the gear, it is S-shaped or inverted S-shaped. The letter-shaped portion is compressed in the substantially vertical direction of FIG. 7 or FIG. 8 (almost perpendicular to the pressure contact surface), and the pressure contact surface hardly tilts to the left or right in the figure, even if the gear stop position is the polarity of the stepping motor. Even if the position is changed, the pointer is stopped at the position where the pointer is advanced. Therefore, when the stepping motor is moved again, the step time for matching the polarities of the magnet and the rotor is stopped at the position where the pointer is advanced. Since it is equal to the time allowed, the time indicated by the pointer becomes accurate and the object of the invention can be achieved.

いる。When the door 1 is rotated, the tip of the reset lever 2 first contacts the reset pin 8 to stop the electrical action of driving the stepping motor, and the door 1 is further rotated so that the tip of the train wheel setting lever 4 is moved. When the press contact surface 4d with the gear 7 provided is in contact with the gear 7, and when the rod 1 is rotated about the rotation center 5 to the meshing position of the rod 1 and the lever 10 shown in FIG. 8, the train wheel setting lever 4 is moved. The inverted S-shaped elastic portion is compressed while increasing the pressure contact force between the gear 7 and the pressure contact surface 4d of the train wheel setting lever 4. At this time, the direction of the pressure contact surface is prevented from changing by forming an elastic portion in an inverted S shape.
