And is hidden behind and comes to the state of FIG. In this position, the rack 58 indicates that the operating portion 58b presses the switch 7b and the rack 58 is in the lower movement position. Rack 58
Cannot move down any further, so the pinions 46a, 57
a cannot rotate, but since the drive motor 4 continues to rotate, the rotation from the motor 4 is not transmitted to the slip wheels 46, 57.
Is not transmitted to the pinions 46a and 57a.

When the switch 7b is pressed as described above, the predetermined contact of the control board D is closed, the second drive motor 6 is driven, and the rotation is transmitted by the third drive wheel train C. Then, the rotating gear 67 rotates counterclockwise to rotate the door 11 270 degrees counterclockwise, and the rotation is stopped by a degree determining member (not shown) at a position overlapping the front surface of the door 10, and the state shown in FIG. 3 is obtained. . Since the drive motor 6 continues to rotate, the rotation transmitted from the motor 5 is not transmitted to the rotary gear 67 by slipping on the slip wheel 65.

Thus, the first, second and third drive trains A, B and C are all visible in the state shown in FIG.
As the drive gears 63, 51, 54, and 43 in the drive train are rotated, the decorations 30, 31, 33, and 34 act and the cam gear 64 The ornaments 32 and 35 perform by swinging the pair of arms 8 by rotation.

In order to return to the original state of FIG. 1 after the performance, if the drive motor 4 is driven in the reverse direction, the doors 12, 13, 14 and 15 return to the original positions, When the rack 58 is in the up position, the operation unit 58 pushes the switch 7a, and the rack 58 is in the up position.

When the rack 58 is moved upward, the door 12 is
From position (d) to position (c), the front door 12
Since the upper end of the rack A contacts the inner surface of the base plate 2 and cannot be moved any further, the rear door 1
7B, the front door 12A is moved away from the rear door 12B, and the rear door 12B is brought into contact with the inner surface of the main plate 2 as shown in FIG. 7B. Then, the rack 58 stops moving and returns to the original state as shown in FIG. In the state of FIG. 7A in which the door 12 is closed, the front surface of the front door 12A is aligned with the front surface of the third door 13, and in the state of FIG. 7D in which the doors 12 and 13 are opened, The door 12 is located behind and behind the door 13. this is,
As described above, the front door 12A and the rear door 12B are connected by the parallel link 1.
This is because the front door 12A and the rear door 12B are configured to approach each other when the spring 12e is released, and when the doors 12 and 13 are closed, the spring force of the spring 12e is applied. By moving the front surface of the front door 12A forward, the front surfaces of the doors 12 and 13 can be aligned. When the switch 7a is pressed, the drive motor 6 is driven to rotate in the reverse direction, so that the door 11 rotates 270 degrees clockwise and returns to the original state.

In the above example, the door 11 is restricted to rotate by 270 degrees, but it may be restricted to rotate by 90 degrees, or the door 11 may not be provided.

The present invention is not limited to driving both drive motors together as described above, but only one of the drive motors is driven, only the selected door is opened, and the decoration which has become visible is driven. Things are also possible.

[0031]

Since the present invention is constructed as described above, the drive train for driving the decoration can be used up to the front stage of the slip wheel in the drive train of the door, so that the structure is minimized. Can be something. Therefore, the configuration can be simplified, the manufacturing cost can be reduced, and the size of the device can be reduced. Since both the door and the dial are used, since the dial is opened and the decoration is driven, the effect is improved. When many doors are open, the front of the doors can be almost aligned when the doors are closed, while the front side of the doors can be almost aligned with the fixed doors. This improves the appearance of the dial.
