Although not shown, the electronic component and the time setting contact device 4 for driving the clock lubrication heat are fixed to the substrate 2.

The time setting contact device 4 is approximately It consists of a stationary contact member 6 which is bent in a shape of a child and a movable contact member 10 which has elasticity and is provided with a tongue section 8 and an engaging portion 9 which are foldable with the stationary contact member 6.

Although not shown, the fixed contact member 6 and the movable contact member 10 are connected to a power source and an alarm sound generating device, and the alarm sound generating device operates by contacting both contact members.

2 is a cross-sectional view of the time setting cam mechanism, and the time setting gear 14 is rotatably supported on the mechanism receiving plate 12 as a time setting set difference for arbitrarily setting the time setting time by external operation. .

The hour hand pipe 18 is inserted inside the time setting pipe 16 integrally formed with the time setting gear 14, and the minute hand pipe 20 is inserted inside the hour hand pipe 18. The hour hand pipe 18 and the minute hand pipe 20 each have a hour hand gear 22 and a minute hand gear 24, and constitute a well-known clock rotation.

A flow cam 26 is mounted between the hour hand gear 22 and the time setting gear 14, and the protrusion cam 28 and the time setting click 30 are formed on the flow cam 26.

As the projection 28 engages with the perforation 32 installed in the hour hand gear 22, the flow cam 26 can rotate integrally with the hour hand gear 22 and move in the axial direction at the time setting time. It has the function of time setting delivery vehicle that delivers setting time.

As shown in FIG. 1, the movable contact regulating member 34 is axially slidable in the vicinity of the time setting gear 14 to uniformly press the flow cam 26 in the direction of the time setting gear 14. .

The axial structure of the movable contact regulating member 34 is shown in FIG. 3, and the pressing column protruding from the holding member 36 and the case 38 having a substantially V-shaped cutout 36a formed in the instrument receiving plate 12 is shown. (V) 40.

The movable contact regulating member 34 can be easily woven into the cutout portion 36a of the holding member 36 of FIG. 3 in an extremely simple operation only by mounting the shaft 35 of the movable contact regulating member 34. .

In addition, the shaft 35 is easily maintained by the upper portion of the cutout portion 36a blocked by the pressing column 40 by the combination of the case 38 and the instrument receiving plate 12.

In addition, as shown in FIG. 4, the movable contact member 34 is provided with a dense protrusion 42, and the dense protrusion 42 is polymerized with the tongue section 8 of the movable contact member 10. As shown in FIG. Is placed on.

From the above configuration, the flow cam 26 rotates integrally with the hour hand gear 22 so that the time setting clicks 30 and 31 of the flow cam 26 are the time setting grooves 15 and 17 of the time setting gear 14. The movable contact regulating member 34 is movable in the axial direction by falling in the.

The magnetic stop switch body 44 is shown in FIG. 4 and FIG. 5, and is comprised from the operator 46, the press part 48, the plate 50, and four clicks 52. As shown in FIG.

A positioning hole 54 is formed in the plate 50, and the positioning hole 54 engages with the convex portion 56 formed in the case 38 to hold the switch body 44 at a predetermined position.

The four clicks 52 are elastically engaged with the side walls 60 of the perforations 58 formed in the case 38, as shown in FIG. 5, whereby the switch body 44 is moved in both arrows A and B. .

At the tip of the pressing section 48, as shown in FIG. 4, an inclined surface 49 facing the engagement section 9 of the movable contact member 10 is formed.

With the above configuration, when the switch body 44 moves in the direction of the arrow A and the inclined surface 49 of the pressing portion 48 rises up to the engaging portion 9 of the movable contact member 10, as shown in FIG. Likewise, the section 8 is elastically deformed in the direction of the arrow C. FIG.

On the other hand, the fixed contact member 6 and the movable contact member 10 can be contacted.

The embodiment of the present design is configured as described above and the operation thereof will be described next.

First, when the switch body 44 is held at the position of the magnetic stop of FIG. 4, the pressing part 48 and the engagement part 9 are separated, and thus the movable contact member 10 does not elastically deform.

As a result, the fixed contact member 6 and tongue tongue 8 become incapable of contact, and the time setting clicks 30 and 31 of the flow cam 26 shown in FIG. Even if the dense projection 42 of the movable contact regulating member 34 falls to the dashed line position by dropping to (15, 17), the magnetic noise generating device (not shown) does not operate.

In addition, when the switch body 44 is moved in the direction of arrow A in FIG. 4 and maintained at the self-locking disengagement position in FIG. 6, the inclined surface 49 of the pressing portion 48 is raised to the engaging portion 9 of the tongue section 8. FIG. In this way, the tongue piece 8 is elastically deformed in the arrow C direction.

In this state, the time setting clicks 30 and 31 of the flow cam 26 of FIG. 2 are separated from the time setting grooves 15 and 17 of the time setting gear 14, and the movable contact regulating member 34 is raised. If the projection 42 is located at the solid line position in Fig. 6, the tongue section 8 is in contact with the densely raised projection 42, so that it is not in contact with the fixed contact member 6.

However, when the time setting clicks 30 and 31 engage with the time setting grooves 15 and 17 and the movable contact member 34 moves in the axial direction at the time set time, the compacted protrusion 42 is in the chain position of FIG. Since the tongue section 8 and the fixed contact member 6 come into contact with each other, the magnetic noise generating device, not shown, is operated.

As described above, according to the illustrated embodiment, the movable contact member 10 of one time-set contact position 4 provided on the substrate 2 is in a state of elastic deformation and release of elastic deformation by the movement of the switch body 44. Only when the state is selected and the elastic deformation state is possible, the movable contact member 10 can perform the function of the conventional time setting cam contact in conjunction with the time setting cam mechanism.

In addition, in the illustrated embodiment, the tongue section 8 of the movable contact member 10 is set to be interlocked with the conventional time setting cam mechanism through the movable contact member 34, but the tongue setting section 8 extends directly to the time setting cam. Can be linked with the mechanism.

According to this configuration, the parts score is further reduced.

In addition, the engaging portion 9 of the tongue section 8 of the movable contact member 10 of FIG. 1 is formed by a cutout portion 11, which is protruded and the tongue section 8 forms the movable contact regulating member 34. FIG. Although it is adjusted to be pressed by an optimal elastic force, the cutout part 11 can be implemented even if it is not installed in particular.

In addition, although the time setting contact device 4 is mounted on the board | substrate 2, this can also be attached to the instrument receiving plate 12 or the case 38. As shown in FIG.

In addition, the switch body 44 is mounted to the case 38 so that the case 38 moves in the planar direction, but the switch body 44 is mounted to be movable in the vertical direction with respect to the plane of the case 38. The object of the present invention is also achieved.

As described in detail above, the present invention can set the automatic contact member of one contact device to either the state of elastic deformation or the release state of elastic deformation by an operator of an externally operated magnetic stop switch device. The movable contact member is elastic Only when it is set in a deformed state, the time setting cam contact function that works with the conventional time setting cam mechanism can serve.

Therefore, the two contact devices for the conventional time setting cam contact and the magnetic stop switch are reduced to one, and at the time of assembly, the movable contact member is not given any elastic force by simply setting the switch body to the magnetic stop state. .

As a result, the parts can be easily managed, and the positional shift of the watch parts and the injuries of the parts are eliminated by the elastic force of the elastic member during assembly, thereby simplifying the assembly and significantly reducing the manufacturing cost.

Furthermore, since there is only one contact portion, it is possible to reduce the occurrence rate of contact failure compared with the conventional one and to improve the reliability.
