In the decorative device configured as described above, the wiring for the motor 111 and the like are connected to a control system (not shown) provided in the mechanical timepiece body. In this apparatus, the dolls A1 to A4, B1 to B4 are controlled by a control system (not shown) in a positional relationship as shown in FIG.
4 is put on standby, and when the hour comes, the motor 111 is driven to control the carry-out and replacement of the doll located on the rear side to the front side and the reciprocating motion control in a predetermined range.

Next, an operation example of the above configuration will be described.
For example, in the initial state as shown in FIG. 2, when the hour has passed, the motor 111 is driven by the control system, and the dolls B1 to B4 located on the rear side of the apparatus are turned, for example, counterclockwise to the front side. Dolls B1-B4 and A1-A
The operation is temporarily stopped in a state where the positions 4 and 4 are exchanged.

Next, the rotation direction of the motor 111 is switched at predetermined intervals. Thereby, the dolls B1 to B4 (A
1 to A4) are reciprocated only for a predetermined distance. This reciprocating movement distance is, for example, the distance of two cams 101d in the triangular wave-shaped guide portion 101c shown in FIG.

When the rotation direction of the timing belt 104 is counterclockwise or clockwise in FIG. 2, the receiving plate upper surface sliding portion 107c2 of the receiving plate sliding portion 107c of the decorative body mounting member 107 and the sliding pin 17c3 are moved in the traveling direction. , And slides along the guide groove 101c so as to be located behind the doll attached to the decorative body attachment shaft 107b. Immediately after the rotation direction is reversed, the upper plate sliding portion 1
When 07c2 and the sliding pin 17c3 are located in front of the doll attached to the ornamental body attaching shaft 107b in the traveling direction, the sliding direction is temporarily stopped in the next cam 101d.

Here, the movement of the doll will be considered. In the counterclockwise direction, when the receiving plate upper surface sliding portion 107c2 and the sliding pin 107c3 slide along the guide groove 101c between the two cams 101d, for example, ascending right in FIG. Since the movement of the lower end of the mounting shaft 107b is regulated by the movement of the slide pin 107c3 inserted into the guide portion 101c, the decorative body mounting shaft 107b rotates clockwise. That is, the doll is rotated right. In this state, when the sliding pin 107c3 reaches the next cam 101d, the rotation direction of the ornamental body mounting shaft 107b is reversed, and the sliding pin 107c3 slides along the guide part 101c descending to the right and the next cam 101d. It rotates counterclockwise until it reaches 101d. That is, the doll rotates left.

Similarly, in the case of clockwise rotation, when the sliding portion 107c2 on the upper surface of the receiving plate and the sliding pin 107c3 slide along the guide groove 101c descending to the right, the lower end of the decorative body mounting shaft 107b is rotated. Since the movement of the part is restricted by the movement of the slide pin 107c3 inserted into the guide part 101c, the decorative body mounting shaft 107b rotates clockwise. That is, the doll is rotated right. In this state, the sliding pin 10
When 7c3 reaches the next cam 101d, the direction of rotation of the decorative body mounting shaft 107b is reversed, and the guide portion 1 rising to the right
The sliding pin 107c3 slides along the first cam 1c.
Rotate counterclockwise until it reaches 01d. That is, the doll rotates left.

Therefore, the doll B1 located on the front side of the device
Since B4 (or A1 to A4) changes the rotation direction from left to right with the cam 101d as a boundary during the reciprocating motion described above, the motions are precise and interesting. .

After such a dense and interesting reciprocating motion is performed for a predetermined time, the reciprocating motion is stopped, and then the doll is replaced again, and the reciprocating motion described above is performed. After the above operation is repeated several times at every hour, the state as shown in FIG. 2 is maintained until the next hour.

Note that, even if the dolls waiting on the rear side of the apparatus, for example, the faces are not aligned, they are aligned in one direction by the cam 101e provided on the rear side of the apparatus and conveyed to the front side of the apparatus. .

Since the decorative body conveyed to the front side of the apparatus only reciprocates a predetermined distance, the direction of rotation changes rapidly between right and left, and a precise, fun and interesting movement can be realized.

The guide groove 101c on the rear side of the apparatus is formed in a straight line shape, and both ends of the straight region are formed in a triangular wave shape such that the apexes come inside the receiving plate 101, respectively. Since the cam 101e having a square shape continuous to the outer side of the vertex is formed at the vertex portion, the direction of the doll waiting on the rear side of the apparatus may be set to the rear side of the apparatus even if the faces are not aligned. The cam 101e provided can be aligned in one direction and transported to the front side of the apparatus.

In this embodiment, the receiving plate 101
Cams 101d and 10 formed in the guide groove 101c
1e is formed as a rectangular groove, but is not limited to this. Any groove can be used as long as it can temporarily stop at the apex, and a predetermined frictional force is applied to the sliding pin 107c3. If the stop state can be maintained, the reversing action of the above-described receiving plate upper surface sliding portion 107c2 can be exhibited simply by forming the vertex of an acute triangle, for example. Further, it goes without saying that the number, arrangement position, operation control, and the like of the decorative bodies are not limited to the present embodiment.
