In d, a brim 12e is provided above the through hole 11e. Therefore, the protrusion 11f is always located in the through hole 12f and is not lifted up. Also, on the upper surface of the body 12, the protrusion 11f of the head 11
A circular arc-shaped through hole 12f is movably inserted therein, and the rotation angle of the head 11 is restricted by the projection 11f and the through hole 12f.

A device 20 for swinging and driving the character 10 will be described. The drive motor 22 is fixed in the case 21 of the drive device 20 so that the alarm signal of the timepiece is supplied. The drive pinion 22a is fixed to the motor shaft of the motor 22, and the transmission gear 23 meshes with this pinion. A gear 25 is rotatably supported by a central shaft 24 whose both ends are supported by a case 21, and a pinion 23a of a transmission gear 23 meshes with this gear to transmit the rotation. A gear 26 is also rotatably supported on the central shaft 24, and the rotation of the gear 25 is transmitted to the gear 26 via an idler (not shown). A rotating body 27 is concentrically fixed to the gear 26 at each central portion by press fitting, and a drive cam 28 is fixed to the protrusion 27a of the rotating body 27 by press fitting. That is, the rotating body 27 and the drive cam 28
Are integrally rotated by the rotation of the gear 26. The drive cam 28 includes an eccentric cam 28a and a ratchet wheel 28b.

In the character 10, the lower end of the body portion 12 is inserted between the opposing support plate portions provided upward from the front and rear walls of the case 21 of the drive device 20, and by the swing center shaft 30 serving as a support means. It is swingably supported to the left and right. Bifurcated portions 15a and 15b extend downward from the body portion 12 of the character 10, and are inserted inside through an opening 21a opened in the case 21 to hold both sides of an eccentric cam 28a.

An actuating lever 16 is vertically positioned at a substantially central portion of the body portion 12. The actuating lever 16 has vertical grooves 16a and 16b provided at two positions, and the lower end of the actuating lever 16 engages with the ratchet wheel 28b.
16c is provided. A guide shaft 12g protruding to the inner surface of the body 12 penetrates the long groove 16a, and a swing center shaft 30 which is a support means of the character 10 penetrates the long groove 16b. Actuating lever 16
A coil spring 17 is hooked between the guide shaft 12g and the guide shaft 12g, and applies a spring force to the actuating lever 16 in a direction of engaging the claw 16c with the claw wheel 28b. The upper end of the actuating lever 16 is located between the shaft 13 and the pin 13b, and a U-shaped groove 16d for locking the pin 13b is provided.

With such a structure, the alarm signal is sent to the drive motor.
When supplied to 22, the rotation of the drive pinion 22a is sequentially transmitted to rotate the gear 26, the rotating plate 27, and the drive cam 28. Drive cam 28
Rotation of the eccentric cam 28a causes the two forked portions 15a and 15b that sandwich the opposite sides of the eccentric cam 28a to reciprocate to the left and right, and the character 1
0 swings left and right around the swing center axis 30. Since the center of gravity of the head 11 of the character 10 is offset forward and downward from the support shaft 12d that supports the head 11,
1 does not completely follow the swinging motion of the character 10, and a rotary motion with a one-tempo delay is added to this.

That is, as shown in FIGS. 4 and 5, when the eccentric cam 28a is positioned symmetrically, the character 10A maintains an upright posture via the bifurcated portions 15a and 15b. A view of this state viewed from directly above is shown in FIG. When the eccentric cam 28a rotates and its long diameter portion is located on the left, the two-forked portion 15
The character 10B inclines to the right through a and 15b. At this time, as described above, the center of gravity of the head portion 11 is offset with respect to the receiving portion, so that the protrusion 11
f moves in the arc-shaped through hole 12f, and only the head 11 rotates counterclockwise. When the eccentric cam 28a is further rotated and its long diameter portion is positioned to the right, the character 10C inclines to the left via the forked portions 15a and 15b. At this time, since the center of gravity of the head is deviated in the same manner as described above, the protrusion 11f moves in the arc-shaped through hole 12f as shown in FIG. 5 (a), and only the head 11 moves clockwise. Rotate to.

As described above, the drive device 20 swings the character 10 left and right, the head 11 of the character 10 reciprocally rotates by a predetermined angle, and a person shakes his body and shakes his head. In addition to this movement, both arms of character 10
12a also rocks up and down. That is, the rotation of the drive cam 28 also rotates the ratchet wheel 28b in the clockwise direction in FIG.
The claw 16c overcomes the spring force of the coil spring 17 and goes over the claws of the ratchet wheel one by one. Therefore, the operating lever 16 reciprocates up and down, and the pin 13b locked in the U-shaped groove 16d reciprocates up and down. The reciprocating motion of this pin causes the lever 13a
Swings, and the arm 12a fixed to the shaft 13 is driven to swing.

[Effect] Since the character drive device of the present invention having the above-described configuration swings the character by a simple mechanism and simultaneously rotates the head, when driving with a melody, it becomes a motion just like dancing, This complex movement adds to the fun. In addition, it can be provided at low cost.
