2. Description of the Related Art As a timepiece device, an alarm mechanism such as a buzzer or a chime is activated at a desired set time,
Alternatively, a so-called alarm clock that drives a radio or the like connected to a clock device as an alarm mechanism, and a time clock that issues a chime notification when the hour comes, for example, are known.

In an alarm clock, there is provided a reference device for setting a desired time at which an alarm operation is required and performing an alarm operation when the set time coincides with an instruction time of the clock. Generally, as this guide device,
Including the hour hand wheel linked to the clock wheel train and the guide setting wheel provided from the outside that is operated from the outside and setting the guide hand to the desired set time, using the cam mechanism provided on the hour hand wheel and the guide setting wheel Various structures have been proposed for mechanically controlling the movement of a reference contact or the like for controlling an alarm mechanism (for example, see Japanese Utility Model Publication No. 63-10542).

In addition, as a timepiece, for example, through holes are formed in each gear of a wheel train in a drive system for a second hand and each gear in a wheel train in a drive system for a minute hand, and a light emitting element is connected to the light emitting element through the through holes. Various proposals have been made such that a light-receiving element is opposed to the light-emitting element, and each light-emitting element is provided with a pointer position detecting device that detects when light emitted from the light-emitting element is received by the light-receiving element. (See, for example,

According to the present invention, the rotation of the minute wheel is transmitted to the intermediate wheel, where the rotation speed of the minute wheel is reduced and transmitted to the hour wheel. Thus, the hour wheel (not shown) rotates by 30 ° per hour, and makes one revolution in 12 hours. Also,
The rotation of the intermediate wheel is transmitted to an intermediate transmission unit that is a part of the time notification mechanism. As a result, the intermediate transmission portion is rotated at a predetermined speed, and is rotated at a predetermined angle for a predetermined time. The detection unit detects that the intermediate transmission unit has rotated by a predetermined angle, and thereby the control system determines that the time has reached the correct time.

According to the present invention, the rotation of the intermediate wheel is transmitted to the intermediate transmission pinion which is a part of the timing mechanism, and this rotation is transmitted to the hour wheel. As a result, the hour wheel rotates at a predetermined speed, and at this time, the origin index portion also rotates integrally.
Here, one rotation of the hour wheel is detected by the detection unit cooperating with the origin index unit when the origin index unit is rotated once.

b, and the rotation of the minute wheel 20
Is transmitted to

As a result, the hour wheel 32 makes one revolution per hour. With the rotation of the hour wheel 32, the movable element 33c having the elasticity of the contact switch comes into contact with the side surface of the origin indicator 32a of the hour wheel 32. The mover 33c slides while maintaining the state of contact with the origin index portion 32a,
Deflected away from the fixed contact 33b with the rotation of the hour wheel 32.
The contact state for a is released. As a result, the movable element 33c is fixed to the fixed contact 33b by the urging force when the contact state is released.
And contacts the fixed contact 33b. Fixed contact 3
When the movable member 3b and the mover 33c come into contact with each other, the contact switch is turned on, and a signal indicating this on state is output to the output terminal 3
3d and 33e are output to a time control system via a lead wire (not shown), and are reported as an hour.

A guide needle (not shown) is attached to the guide pipe 21a. The guide needle is set by rotating the guide correction shaft 22 in either the forward or reverse direction at a desired time when an alarm operation is required. You. Then, with the alarm switch (not shown) turned on, the reference cam 210 is also rotated in the same direction with the rotation of the hour wheel 19 described above. Guide cam holes 21b and 21c of guide setting vehicle 21
To fall. As a result, the contact 213 is fixed to the fixed contact plate 21.
2 and the signal is output to a control system (not shown), whereby the alarm mechanism is activated to notify that the set time has come.

During manual correction, the head 23b of the manual correction shaft 23 is manually rotated clockwise or counterclockwise. The rotation of the manual correction shaft 23 is controlled by the minute wheel 20.
Is transmitted to the minute hand pipe 18a of the minute hand wheel 18 via the center wheel and to the hour hand wheel 19 via the pinion of the minute wheel 20. At this time, since the minute hand pipe 18a of the minute hand wheel 18 is in phase with the manual correction shaft 23, the minute hand pipe 18a rotates at the same speed as the manual correction shaft 23, and the hour hand wheel is rotated at a reduced speed. Thereby, it is manually corrected at a desired time.

As described above, according to this embodiment,
Using a movement for alarm, the shaft end of the minute wheel 20 is projected from the lower plate 11, and the minute transmission kana 31 is attached to the shaft end, and the hour wheel 32 and the detection unit 33 are at predetermined positions. The lower plate 11 is moved so that the guide pipe 21a or the like protrudes toward the front side of the timepiece with respect to the time mechanism receiving plate 30 provided.
Is fixed by screwing
The clock device having both the alarm function and the alarm function can be easily configured by using only one movement, and thus there is an advantage that the component management can be simplified and the cost can be reduced. In addition, kana 31 and hour car 32
By appropriately selecting the gear ratio of the pinion portion 32b,
It is possible to realize not only a time-based timing function but also a desired time-based timing function.

In this embodiment, a timepiece having both the alarm function and the alarm function has been described as an example. However, for example, the urging spring 211 and the fixed contact plate 212 are not provided in the configuration of FIG. With this configuration, it is possible to realize a timepiece device having only a time notification function.
