This timepiece normally displays the current time in analog form, and has a hand 30 composed of a minute hand 28 and an hour hand 29.
When does not indicate the hour, the decorative body 44 is submerged on the back of the indicator 42 as shown in FIG.

However, at the hour, as shown in FIG. 4, all the index pairs 40 rotate clockwise by 90 ° about the mechanism rotation axis 48. Then, the rotating decorative body 44 appears from behind the index pair 40. At the same time as the start of the mechanism operation, music is started by a music generating means (not shown).

Next, the index pair 40 and the decorative body 44 rotate clockwise around the mechanism rotating shaft 48 while maintaining their positions, and return to the initial position. The time required during this time is 15 seconds. Note that FIG. 5 shows a mechanism rotating shaft 48 in which the index pair 40 and the decorative body 44 maintain their positions.
Shows a state rotated by 180 ° around the center.

Next, when the index pair 40 and the decorative body 44 rotate clockwise 360 ° about the mechanism rotating shaft 48 while maintaining the mutual positions, the mechanism operation temporarily stops.

The time required during this period is 15 seconds.

The mechanism motor 46 continues to rotate for several seconds, but is constructed so as to prevent the mechanism operation by a known slip mechanism.

Thereafter, after the rotation of the mechanism motor 46 is stopped, it starts to reverse. That is, the index pair 40 and the decorative body 44 start rotating counterclockwise around the mechanism rotation shaft 48 while maintaining the mutual positions.

Then, when rotated 360 °, the decorative body 44 is rotated.
Stops at that position, and only the index pair 40 rotates 90 ° counterclockwise about the mechanism rotation axis 48.

Then, the decorative body 44 sinks to the back of the indicator 42 and the music by the music generating means stops. The time required during this period is 15 seconds.

Although the mechanism motor 46 continues to rotate for several seconds, a known slip mechanism is used to prevent the mechanism operation.

Thus, the mechanism operation ends.

Next, this mechanism will be described with reference to FIGS. 6 and 7. FIG.

A spring (not shown) is provided between the index pair 40 and the decorative body 44 to prevent skewing.

The mechanism rotating shaft 48 includes a concave portion 60 provided on the index pair 40 side and a convex portion 6 provided on the decorative body 44 side.
2, and are connected at the joint 48a.

FIG. 6 shows a normal rotation, and shows a mechanism for rotating both the index pair 40 and the decorative body 44 after only the index pair 40 rotates. The arrow in the figure indicates the moving direction of the driven plate 58, and as shown in FIG.
8 is driven by the driving plate 56.

Then, as shown in FIG. 6 (b), the projection 62 provided on the driven plate 58 engages with the recess 60 provided on the driving plate 56, so that they are integrally rotated. I do.

FIG. 7 shows a mechanism at the time of reverse rotation in which the index pair 40 and the decorative body 44 that have been rotated together are separately rotated. The arrow in the figure indicates the direction in which the driven plate 58 moves.

The protrusion 62 provided on the driven plate 58 engages with the recess 60 provided on the drive plate 56, so that the drive plate 5
6 and the driven plate 58 rotate integrally. However, when the convex portion 62 provided on the driven plate 58 comes off the concave portion 60 provided on the driving plate 56, only the index pair 40 rotates.

Hereinafter, the operation of the mechanical timepiece 1 according to the second embodiment of the present invention will be described.

The same members have the same reference characters allotted, and their configurations will not be described because they are the same.

The decorative body 44 is hidden behind the index 42. At the right time, the decorative body 44 rotates clockwise about the mechanism rotating shaft 48 and appears from the back of the index 42. Simultaneously with the start of the mechanism operation, music is started by music generation means (not shown).

After the index pair 40 is rotated clockwise by 90 ° about the mechanism rotation axis 48, the index pair 40 and the decorative body 44 are kept at the mutual positions from the initial position while maintaining the mutual positions. Rotate 360 ° clockwise around.

After 15 seconds from the start of the mechanism operation, the mechanism operation is stopped, but the mechanism motor 46 continues to rotate for several seconds. However, a known slip mechanism is configured to prevent a mechanism operation.

Next, the index pair 40 and the decorative body 44 rotate counterclockwise around the rotating shaft 48 from the 360 ° to the initial position while maintaining the mutual positions.

Next, the operation of the index pair 40 is stopped, and only the decorative body 44 is rotated counterclockwise by 90 °, and the decorative body 44 is immersed in the back of the index 42. At the same time, the music by the music generating means (not shown) stops. However, a known slip mechanism is configured to prevent a mechanism operation.

This completes the mechanism operation.
