る。(Prior Art) In a crystal oscillation type watch, when stopping one of the high-speed wheels, such as the second hand wheel, a regulating lever that can be operated from the outside of the watch body is provided, and the frictional resistance of this lever is reduced. One that utilizes engagement is known. In this case, use the shaft of the second hand wheel,
In order to bring the elastic lever into elastic contact with the side surface of this shaft and stop the vehicle, it is necessary to apply strong side pressure to the shaft. However, applying strong side pressure may damage the tenon at the end of the shaft.
For this reason, conventionally, for example, when stopping the rotation of a balance wheel, one end of a leaf spring is pressed into contact with the balance wheel (Utility Model Publication No. 10616/1973), or a specially shaped cam is installed coaxially on the idler wheel or rotor. A device that engages a stop lever with this cam to stop it (Japanese Patent Laid-Open No. 54
-92651, JP-A-50-104970) are known.

Therefore, not only is it necessary to specially manufacture the cam, but the structure itself is complicated, and the timepiece assembly process is also complicated.

そこで本考案の目的は、高速段の車に従来から

回転を停止せしめるように構成されている。(Means for Solving the Problems) The feature of the present invention is that the swingably supported stop lever is provided with an elastic arm and an operating arm, and this elastic arm is used for high-speed self-starting watches. It can be elastically contacted from the side with the shaft of one of the wheels in the gear train of the stage, and the operating arm is provided with an operating piece, and this operating piece has its tip end so that it can be operated from the outside. A click protrusion is formed in the opening of the main plate to protrude outside the main plate from the opening of the main plate, and the opening is formed with a click protrusion that protrudes inward from the rotation locus of the operating piece in order to hold the operating piece in position. When the elastic arm of the stop lever comes into elastic contact with the shaft of the car from the side, a part of the outer circumferential surface of the shaft of the car is attached to prevent excessive lateral pressure from being applied to the shaft that supports the car. A protrusion is provided, and the rotation of the vehicle is stopped by elastic contact between the elastic arm of the stop lever and the protrusion.

転し始める。(Function) Therefore, when the operating piece of the stop lever is grasped and moved from one end to the other end through the opening of the main plate, the elastic arm of the stop lever moves to the high speed stage of the watch. The elastic arm makes elastic contact with the shaft of the car, and when it is in elastic contact with the shaft, the elastic arm reliably stops the car with a weak pressure due to the protrusion of the shaft.
When the stop lever is returned to its original position, the car starts rotating again.

A clock wheel train 3 is pivotally supported by a middle plate 2 and a rotor 6 is located between the magnetic poles of a stator 5 around which a coil 4 is wound. A wheel 10, an intermediate wheel 11, a minute wheel 12, a date wheel 13, and an hour wheel 14 are engaged in sequence. A circuit board 16 provided with circuit elements and circuit wiring (not shown) is fixed to the bobbin 15 of the coil 4.

スであり、２３は文字板である。 By the way, a stop lever 18 is swingably supported on a shaft 17 that hangs down from the main plate 1, and this lever has an operating arm 18a and an elastic arm 18b, and an operating piece 19 at the tip of the operating arm 18a. is standing up. The tip of the operating piece 19 protrudes outward from an opening 20 formed in the upper case 1 as shown in the third diagram, and this opening has an inner surface shape that approximately matches the rotation locus of the operating piece. . As shown in FIG. 2, the opening 20 has a protrusion 2 that protrudes inward from the rotation locus of the operation piece 19 and performs a click action.
0a is formed. The tip of the elastic arm portion 18b can come into elastic contact with the rotor shaft 6a. A plurality of axial protrusions 21, 21 are formed on a part of the outer peripheral surface of the rotor shaft 6a. Note that 22 is a lower case, and 23 is a dial.

作動について述べると、通常時にはロータ６の
回転により時計輪列３を介して秒針車１０、分針

先端と弾接し、ロータ６は回転することができな
くなり、時刻は丁度０秒で停止する。 When adjusting the time, for example, when the second hand points to exactly 0 seconds, the protruding end of the operating piece 19 shown by the chain line in FIGS. 20a and push down to position the operation piece 19 at the solid line position. Then, the stop lever 18 swings counterclockwise, and the tip of the elastic arm 18b touches the rotor shaft 6.
a, the protrusions 21, 21 elastically contact the tips of the elastic arm portions 18b, the rotor 6 is no longer able to rotate, and the time stops at exactly 0 seconds.

ついで分針、時針を合わせ時刻信号を待ち、丁

起動する。 Next, set the minute hand and hour hand, wait for the time signal, and when the time exactly matches, turn the operating knob from 19 to 19'.
When the rotor 6 is moved to , the rotor 6 is released and immediately starts automatically.

弾性腕部１８ｂを突起２１，２１に接触しただ

させることができる。 Since the rotor 6 can be completely stopped simply by contacting the elastic arm portions 18b with the protrusions 21, 21, the lateral pressure on the rotor shaft 6a is small, and the tenon at the end of the rotor shaft is not damaged. Since the shaft 6a rotates eight times per second in this example, the two protrusions 21,
21, the rotor shaft 6a can be stopped within 1/16 second.

防止することができるなどの優れた効果がある。(Effects of the invention) As described above, the invention does not require a complicated circuit configuration, and has a simple configuration that only requires forming a protrusion on a part of the outer peripheral surface of the shaft and adding a stop lever. With a simple operation, you can stop a high-speed vehicle such as the second hand at any position, and you can also restart the second hand with a simple operation, so when adjusting the time, you can stop the second hand or other high-speed vehicle at any position. It is easy to align, and since a part of the shaft of a high-speed vehicle is provided with a protrusion as mentioned above, the lateral pressure of the elastic arm against the shaft of this vehicle is reduced when the vehicle is stopped. It is small and has excellent effects such as preventing damage to the tenon of the shaft.
