Is provided with a reference hand 420 indicating the scheduled time, and the scheduled time is arbitrarily set by the user operating a knob (not shown) for rotating the reference hand 420.

The drive device 700 of this embodiment has a pair of plates 710 fixed to the case 800, a motor 720 installed on the case 800 and the plate 710, and a first rocking body 730 pivotally supported by the plate 710. And a plurality of second oscillators 74 pivotally supported by the first oscillator 730.
0, and a drive mechanism 750 that swings each of the first swing body 730 and the second swing body 740 as the motor 720 rotates. The case 800 and the plate 710 are the supports. In addition, reference numeral 760 is a case 8
00 and the first oscillating body 730. The deformable material 760 is a sheet-shaped member made of cloth or soft rubber, and deforms in accordance with the movement of the first rocking body 730.

The first oscillating body 730 is a casing that constitutes the upper body of the doll, and is constructed by assembling a plurality of members. The plate 710 and the drive mechanism 750 have a first
It is covered by a rocking body.

Each second oscillating body 740 constitutes the arm of the doll, and the base end portion 741 is pivotally supported inside the first oscillating body 730, and the tip portion 742 is the first oscillating body 73.
0 is a member exposed to the outside. The first swinging body 73
An opening for letting the tip portion 742 of the second oscillating body 740 escape to the outside is formed at a key point 0.

The drive mechanism 750 is constructed by assembling a plurality of gears and cams, and operates by the torque of the motor 720. Specifically, a first gear 751 meshed with the output shaft 721 of the motor 720 and axially supported by the plate 710, a second gear 752 meshed with the first gear 751 and axially supported by the plate 710, Two gears 752
And a fourth gear 754 that meshes with the plate 710, a fourth gear 754 that meshes with the third gear 753 and that is axially supported by the plate 710, and that that meshes with the fourth gear and that is axially supported by the plate 710. Fifth gear 7
55, a sixth gear 756 that is attached to the shaft S that supports the plate 710 and the first rocking body 730, and that meshes with the fifth gear 755 and that rotates about the shaft S.
A plurality of seventh gears 757 that are respectively meshed with the sixth gear 756 and axially supported by the first rocking body 730; a first cam C ₁ that is driven by the fourth gear 754 and connects the first rocking body 730; A plurality of second cams C ₂ are provided, which are driven by the respective seventh gears 757 and connect the respective second rocking bodies 740.

First cam C₁Is synchronized with the fourth gear 754.
It is a cylindrical boss that rolls and is installed at a key part of the first rocking body 730.
The cam groove 730a is locked. In addition, the second
Mu C _TwoIs a cylindrical boss that rotates in synchronization with the seventh gear 757.
The cam provided on the base end portion 741 of the second swinging body 740.
It is locked in the groove 741a.

According to this structure, the drive mechanism 750 is operated by the rotation of the motor 720, and the first rocking body 730 rocks with respect to the case 800 and the plate 710 in accordance with the movement of the first cam C _1. At the same time, each second swinging body 740 swings with respect to the first swinging body 730 according to the movement of each second cam C ₂ .

Here, the plurality of seventh gears 757 pivotally supported by the first rocking body 730 mesh with the sixth gear 756 which rotates about the shaft S (that is, the rocking shaft of the first rocking body 730). ing. Therefore, even if the first swinging body 730 swings,
The phases of the sixth gear 756 and the seventh gear 757 are secured.

Therefore, the doll presented by the drive device 700 is rotated by the motor 720, so that the doll shown in FIG.
As shown in the order of (b) to (b), the upper body is shaken left and right while swinging both arms to the left and right.

Further, the feature of this example is that the first oscillating body 730 and one of the second oscillating bodies 740 have different oscillating cycles from each other, and the plurality of second oscillating bodies 740 have different oscillating cycles from each other. is there. Such a difference in the swing cycle is caused by appropriately setting the gear ratio of each gear in the drive mechanism 750 and making the cycles of the first cam C ₁ and the plurality of second cams C ₂ different.

In the case of this example, the doll is constructed so that the right arm is shaken once left and right and the left arm is shaken left and right twice while the upper body is shaken once left and right. Of course, if you change the gear ratio setting,
In addition to this, various patterns are possible. For example, while swinging the upper body twice, one arm can be shaken once and the other arm can be shaken three times.

As described above, if the swing cycles of the first swing body 730 and the plurality of second swing bodies 740 are different, the motion of the doll can be set more complicatedly.

Further, the present driving device 700 includes a motor 720.
The first oscillating body 730 and the second oscillating body 7 depending on the rotation direction of the
The operation mode of 40 is different, and the control unit 100 reverses the rotation direction of the motor 720 to obtain a variety of doll motions.

That is, the first oscillating body 730 and the second oscillating body 7
The moving speed of 40 repeats acceleration and deceleration in synchronization with the rotation of the first cam C ₁ and the second cam C ₂ . And the motor 7
When the rotation direction of 20 is reversed, the timing of such acceleration and deceleration is reversed, so that their operation mode changes.

As described above, if the operation modes of the first oscillating body 730 and the second oscillating body 740 change in accordance with the rotation direction of the motor 720, the taste can be further improved.

Further, by increasing or decreasing the number of rotations of the motor 720,
It is also possible to change the rocking speed of the first rocking body 730 and the plurality of second rocking bodies 740.

In this example, the analog time display section 400 for driving the pointer 510 is adopted, or as shown in FIG. 5, the digital time display section 400 for displaying the time on the liquid crystal is adopted. Good. In the case of the alarm clock 1 shown in the figure, the scheduled time is input by operating the button type operation switch 430.

As described above, the drive device of this example is
It is possible to obtain a very interesting motion, and it can be used very suitably for improving the taste of the alarm clock. Further, the configuration of the drive device of this example can be applied to a mechanical clock and various other toys in addition to the alarm clock.
