【考案の詳細な説明】
本考案は停止装置付き時計機械体に関するもの
である。[Detailed Description of the Invention] The present invention relates to a timepiece mechanical body with a stop device.
近来の水晶発振式時計などの高精度の時計にお
いては、秒の単位まで正確に合わせることが要求
されることからこの要求に答えるため秒針を停止
する機構を設けた時計機械体が知られている。 Modern high-precision clocks such as crystal oscillation clocks are required to be set accurately down to the second, and to meet this requirement, clock mechanisms are known that are equipped with a mechanism to stop the second hand. .
そしてこのような時計機械体の一例としては、
秒針あるいはロータなどに係合可能な規制レバー
が設けてあり、この規制レバーを外部から操作し
て秒針車などに係合せしめるように構成したもの
があり、規制レバーは他の部材とは別個に設けら
れている。 An example of such a clock mechanism is:
There is a regulating lever that can be engaged with the second hand or rotor, and is constructed so that this regulating lever can be operated from the outside to engage the second hand wheel, etc., and the regulating lever is separate from other parts. It is provided.
しかしながら、このような構成によると部品点

に不利であつた。またこの構成では、時計輪列を
構成する歯車の上方あるいは側方に規制レバーを
配設しなければならないため、規制レバーの厚み
や設置スペース確保などにより、小形化、薄形化
に支障を来たすという欠点がある。 However, such a configuration is economically disadvantageous because it increases the number of parts and the number of assembly steps. In addition, with this configuration, the regulating lever must be placed above or to the side of the gears that make up the clock train, so the thickness of the regulating lever and the securing of installation space pose an obstacle to miniaturization and thinning. There is a drawback.
このような問題点を解決するため、実開昭56−
11689号公報において、駆動モータ用のコイルを
巻回するコイル枠に規制レバーを一体的に突設し
たものが提案されている。 In order to solve these problems,
Japanese Patent No. 11689 proposes a coil frame around which a drive motor coil is wound, with a regulation lever integrally protruding from the coil frame.

り、組立の自動化を図る上での障害となる欠点が
ある。 However, although this configuration is effective in reducing the number of parts and the number of manufacturing steps, it is space-efficient because the regulating lever must be placed above or to the side of the wheel train, similar to the conventional example described above. Because of the poor performance, it still has the disadvantage that it is difficult to achieve smaller and thinner designs. In addition, with this configuration, the regulating lever gets in the way when winding the coil around the coil frame, making it difficult to wind the coil, and the regulating lever is easily deformed or damaged, making handling troublesome and making it difficult to assemble. There are drawbacks that become obstacles to automation.
そこで本考案の目的は、停止装置付き時計機械
体の小形化、薄形化を達成することにあり、さら
には組立の自動化を容易にすることにある。 Therefore, an object of the present invention is to achieve miniaturization and thinning of a timepiece mechanical body with a stop device, and further to facilitate automation of assembly.

込み可能となつている。 As shown in FIGS. 2 and 3, each gear forming the timepiece train is rotatably supported by a base plate 1, an upper base plate 2, and an intermediate base plate 3. As shown in FIGS. Rotor 4
A permanent magnet 4 a is fixed to the coil 6 , and a coil 6 is excited by a drive pulse every second output from an electronic circuit (not shown) formed on a circuit board 5 . The rotor 4 is intermittently driven at 180 degrees per second by the generated magnetic flux. The rotation of the rotor 4 is transmitted to the second hand wheel 9 via the drive wheel 8, and the second hand 10 attached to the tip of the second hand wheel 9 is moved intermittently. Furthermore, the rotation of the second hand wheel 9 is controlled by an intermediate wheel 11, a minute hand wheel 12,
It is transmitted to the minute wheel 13 and the hour wheel 14. As shown in FIG. 2, the intermediate base plate 3 is formed with a rotary support portion 3a that pivotally supports the rotor 4, drive wheel 8, second hand wheel 9, intermediate wheel 11, and minute hand wheel 12, and both the upper and lower base plates 1, A positioning post 3b for regulating the positions of the upper and lower base plates is provided at the engaging portion with 2. As shown in FIGS. 1 and 3, the intermediate plate 3 is made of plastic material, and a fulcrum spring portion 3d is integrally formed to extend. The middle part of the regulating arm 3c is connected to the tip of the fulcrum spring part 3d, and the regulating arm 3c extends in the plane direction of the intermediate plate and is swingable about the fulcrum spring part 3d as a fulcrum. One end 3c 1 of the regulating arm 3c faces the lower surface of the second hand wheel 9, and the one end 3c 1 is provided with an engaging portion 3c 2 that can engage with the lower surface of the second hand wheel 9. Further, the other end portion 3c 3 of the regulating arm 3c is provided with an operating portion 3c 4 that penetrates the top plate 2 and projects to the outside, and the operating portion 3c 4 can be pushed in from the outside.

と秒針車９との係合が確実に行なわれる。 Next, the operation of stopping the second hand will be explained. When the operating part 3c4 is operated from the outside and pushed in the direction of the arrow in FIG. 3, the regulating arm 3 swings around the fulcrum spring part 3d, and the engaging part 3c2 engages with the lower surface of the second hand wheel 9. .
This prevents the second hand wheel 9 from rotating and stops. At this time, the fulcrum spring portion 3 of the regulating arm 3c
Since the lower surface near d is supported by the support pillar 1a, when the operation part 3c4 is pressed down, the fulcrum spring part 3d
The engaging portion 3c 2 is not bent and pushed down.
The engagement between the second hand wheel 9 and the second hand wheel 9 is ensured.

車に係合するように構成してもよい。 When the operating portion 3c4 is released, the regulating arm 3c returns to its original position due to the elasticity of the fulcrum spring portion 3d, and the engagement between the engaging portion 3c2 and the second hand wheel 9 is released. 9 starts rotating immediately. Note that when the operating portion 3c4 is pressed down, the lower surface of the operating portion 3c4 comes into contact with the regulating column 1b to regulate the amount of depression, so the engaging portion 3c2 may press the second hand wheel 9 with more force than necessary. In the above embodiment, the tip of the support column 1a is in contact with the lower surface of the regulating arm 3c, but the tip is closely opposed to the lower surface of the regulating arm 3c with a small gap therebetween. It may be configured as follows. Further, in the above-described embodiment, the engaging part provided on the regulating arm is engaged with the second hand wheel, but it is also possible to engage the engaging part with a gear other than the second hand wheel, such as a rotor or a drive wheel. may be configured.

化、薄形化の達成が容易になる。 As explained in detail above, according to the present invention,
A regulating arm for stopping the drive of the timepiece train is integrally formed with the intermediate base plate via a fulcrum spring part that connects the regulating arm in the middle thereof, and is extended in the plane direction of the intermediate base plate, and is attached to the lower surface of the gear of the timepiece train. By arranging the parts to face each other, the number of parts is reduced and the number of assembly steps is reduced, and space efficiency is improved, making it easier to achieve miniaturization and thinning.
