Reference numeral 2 is an operation mechanism such as an alarm mechanism in an alarm clock, an electric music box, a mechanism for an electric doll. In this embodiment, the phosphorus 4 and the hitting ball 6 that comes into contact with the phosphorus 4 by rotation to generate an alarm sound,
The alarm mechanism consisting of is shown as an example.

A motor 8 drives the operating mechanism 2 and also generates electric power. In this embodiment, the motor 8 is composed of a DC brush motor capable of rotating in forward and reverse directions.

Reference numeral 10 designates a motor 8 which is operated by an external operation and is indicated by an arrow mark 3.
4 is a rotation transmission mechanism for power generation that rotates in four directions (hereinafter referred to as "power generation direction"), and includes a rotation lever 12 for operation, and the rotation lever 12 attached to a rotation shaft.
It is composed of a gear 14 that rotates with the gear 2 and a movable gear 16 that meshes with the gear 14 and transmits the rotation to a motor pinion 18 attached to the motor shaft of the motor 8. The movable gear 16 is supported by inserting a rotary shaft thereof into a long hole 20 provided in a main plate (not shown) that also supports other gears, and the rotary lever 12 is indicated by an arrow 22 in the figure.
When rotated in the direction of, the gear 14 is set to move along the elongated hole 20 while maintaining the state of meshing with the gear 14 and mesh with the motor pinion 18 to transmit the rotation of the rotary lever 12.

Reference numeral 24 is a drive transmission mechanism for transmitting the rotation of the motor 8 to the operation mechanism 2, and a movable gear 26 which rotates by meshing with the motor pinion 18 and a rod 32 having a hitting ball 6 attached thereto are attached to a rotating shaft. In addition, a gear 30 that meshes with the movable gear 26 to rotate is provided. Similar to the movable gear 16 described above, the movable gear 26 also has a rotary shaft inserted into and supported by a long hole 28 provided in the main plate, and the motor pinion 18 is in a direction opposite to the arrow 34 (hereinafter referred to as “drive”). When the motor pinion 18 rotates in the power generation direction indicated by the arrow 34, it moves along the elongated hole 28 while maintaining the state in which it meshes with the motor pinion 18, It is set so that the meshing of is disengaged.

Next, the operation of the mechanical components of the power generation mechanism having the above structure will be described. When the motor 8 rotates in the drive direction opposite to the arrow 34 by the electric power supply from the circuit configuration section described later, in this case, one movable gear 16 keeps meshing with the gear 14 and meshes with the motor pinion 18. The movable gear 26 is disengaged, and the other movable gear 26 meshes with both the motor pinion 18 and the gear 30. Therefore, the rotation of the motor pinion 18 is transmitted to the gear 30 via the movable gear 26, the ball 6 is driven to hit the phosphorus 4, and an alarm sound is generated. At this time, since the movable gear 16 and the motor pinion 18 do not mesh with each other, the rotation of the motor 8 is not transmitted to the gear 14 via the movable gear 16.
Therefore, the rotary lever 12 does not move when the alarm sound is generated.

When the motor 8 is externally operated to generate electric power, the rotary lever 12 is rotated in the direction of arrow 22. By the rotation of the gear 14 at this time, the movable gear 16
Moves along the long hole 20 and meshes with the motor pinion 18. Therefore, the rotation of the rotary lever 12 is transmitted from the gear 14 to the motor pinion 18 via the movable gear 16, and the motor 8 rotates in the power generation direction indicated by the arrow 34 to generate electric power. Supply power. still,
When the motor pinion 18 rotates in the power generation direction indicated by the arrow 34, the movable gear 26 moves along the elongated hole 28 while maintaining the meshing state with the motor pinion 18, and the mesh with the gear 30 is disengaged. Therefore, while the rotary lever 12 is being operated, the hitting ball 6 is not driven via the movable gear 26 and the gear 30.

It should be noted that in order to completely disengage the moving gear 16 and the motor pinion 18 in the state where the alarm is issued, the elasticity of a spring or the like is removed in the direction in which the movable gear 16 is detached from the motor pinion 18 as shown by an arrow 36. A member may be provided to urge the member.

Generally, when a DC brush motor is used to generate electric power, and the electric power is used to charge a secondary battery or the like and drive the motor with the charged electric power, the motor must be rotated during power generation unless the connection state is changed. Will be driven in the opposite direction. As described above, in the present embodiment, the operating mechanism is driven by rotating the motor 8 in the power generation direction to generate power and rotating the motor 8 in the drive direction.
As described above, in this embodiment, since it is necessary to switch the rotation direction of the motor 8 during power generation and during driving, this is performed by the circuit configuration unit described later.

FIG. 3 and FIG. 4 are circuit diagrams showing the configuration of the circuit components of the power generation mechanism according to the embodiment of the present invention. Reference numeral 38 is a power storage circuit including a secondary battery or a large-capacity capacitor. Reference numeral 40 denotes a changeover switch circuit, which includes a backflow prevention diode 42 and a changeover switch 44 formed of two externally operable circuit switches. The changeover switch 44 includes connecting pieces 46 and 48 connected to the (+) terminal and the (−) terminal of the storage circuit 38, respectively.
The diode 4 is connected to one connection end 8a of the motor 8 respectively.
2 and a contact point 50 connected via an alarm switch 54
a, 52a and contacts 50b, 52b connected to the other connecting end 8b of the motor 8, and connecting pieces 46, 4
When one of the contact pieces 8 and 8 contacts the contact 50a or 52b, the other contacts the contact 50a or 52b, and when one of the connecting pieces 46, 48 contacts the contact 50b or 52a, the other contacts 50b, 5b.

Next, the operation of the circuit structure portion of the power generation mechanism having the above structure will be described. Normally, as shown in FIG. 4, in the changeover switch 44, the connecting pieces 46 and 48 of the changeover switch 44 are the contacts 5 respectively.
It is in contact with 0b and 52a. In this state, when the alarm time comes and the alarm switch 54 is turned on by the operation of the clock mechanism or the like, the motor 8 is connected to the power storage circuit 38 via the changeover switch 44 and the alarm switch 54. At this time, the connection ends 8a and 8b of the motor 8 are connected to the (−) terminal and the (+) terminal of the power storage circuit 38, respectively, and thereby rotate in the driving direction.

On the other hand, when charging the storage circuit 38 with the electric power generated by the motor 8, the changeover switch 44 is operated to switch the connection pieces 46 and 48 so as to contact the contacts 50a and 52b, respectively. As a result, as described above, the motor 8 is rotated in the power generation direction by an external operation and its connecting end 8 is rotated.

Since the diode 42 prevents the reverse flow of current, the motor 8 does not operate during charging. In addition, the connection piece 4 of the changeover switch 44 is the same as when charging.
When the switches 6 and 48 are brought into contact with the contacts 50a and 52b, respectively, the motor 8 that has been operating in the driving direction due to the power supply from the storage circuit 38 is stopped. It can also be used as a stop switch.

Further, in this embodiment, the alarm switch 5 is used because it is used as an alarm clock as an example.
4 is provided, but when it is used in an operating mechanism other than an additional mechanism for a clock, such as a music box or a doll, a warning switch or a timer switch may be provided instead of the alarm switch 54. good.

[0021]

According to the present invention, since it is possible to generate electric power and drive the operating mechanism by using one motor, it is not necessary to add an electric motor for electric power generation, and the capacity of the battery can be increased or added. No need to build a new one.

In particular, when the power generation mechanism of the present invention is used as an additional mechanism for a timepiece such as an alarm mechanism, it is possible to use not only the alarm and the mechanical mechanism but also the charged electric power to drive the timepiece. It is also possible to provide a timepiece with an additional mechanism that does not require a battery.

Further, since it is not necessary to install a battery, there is no need for storage or maintenance when it is not used for a long period of time.
If you want to move it, you can instantly activate it by charging it.

Furthermore, since the operating mechanism is disengaged from the motor when the rotating lever is operated to generate power, and the rotating lever is disengaged from the motor when the operating mechanism is driven, the load applied to the motor is minimized during both power generation and driving. Therefore, the operation of the rotary lever can be lightened, and the power consumption of the motor can be minimized.
