I'm engaged.

Explanation of operation

Next, operations and actions for turning the dial 30 to play a music box will be described. When the dial 30 is rotated clockwise, the clutch shaft 41 integral with the dial shaft 31 is also rotated clockwise. At this time, the upper spring clutch 42 is engaged with the upper clutch shaft step portion 46 and the upper pinion step. By tightening the portion 48, the upper pinion 43 is integrated with the dial shaft 31 and rotates clockwise. At this time, the crown gear 51 meshing with the upper pinion 43 also rotates clockwise (in FIG. 4). As a result, the crown gear 51, the pinion 53, and the gear 25 meshed with the pinion rotate, whereby the drum 24 rotates in the forward direction and the vibration valve 28 is played to play the music box.

At this time, the lower pinion 45 meshed with the crown gear 51 on the opposite side is forcibly rotated counterclockwise by the crown gear 51, but is engaged with the lower clutch shaft step portion 47 and the lower pinion step portion 49. When the lower spring clutch 44 is loosened, the lower pinion 45 and the lower spring clutch 44 are lightly slipped, so that the rotation of the crown gear 51 is not hindered.

When the dial 30 is rotated counterclockwise, the clutch shaft 41 integrated with the dial shaft 31 is also rotated counterclockwise. At this time, the lower spring clutch 44 is engaged with the lower clutch shaft step portion. By tightening 47 and the lower pinion step 49, the lower pinion 45 is integrated with the dial 30 and rotates counterclockwise. At this time, the crown gear 51 meshing with the lower pinion 45 rotates in the clockwise direction (in FIG. 4). At this time, the upper pinion 43 does not hinder the rotation of the crown gear 51 for the same reason as described above. As a result, the pinion 53 integral with the crown gear 51 and the gear 25 meshing with the pinion rotate, whereby the drum 24 rotates in the forward direction and the vibration valve 28 is played to play the music box. Therefore, no matter which direction the dial 30 is rotated, only the rotational force in one direction is transmitted to the upper pinion 43 and the lower pinion 44, and the drum 24 rotates in the forward direction to produce a music box.

The dial 30 is exposed to the outside through the window 13 provided in the upper container 12. The outer diameter, the exposed length, and the position of the dial 30 are determined by the thumb when the upper and lower containers 11 and 12 are held on the palm. It is set to a value that is easy to operate. Furthermore, the outer diameter size of the containers 11 and 12 is set so as to fit comfortably in the palm of the hand, and is usually made of plastic, wood, metal, cardboard or the like having sufficient rigidity to store and hold the music box body. It is built.

The music box apparatus constructed as described above can be easily assembled as follows. First, the music box body 20 is fixed integrally with the screw 15 through the hole 14 provided in the lower container 11. At this time, the dial 30 is aligned so as to be exposed from the window 13 of the upper container 12. The lower container 11 is completed by engaging with the upper container 12 at the respective step portions 16 and 17 and integrally fixing with an adhesive.

In addition, a part of the lower container 11 has a cut surface 18, which not only prevents rolling when the container is placed, but also a design such as a logo or a character that gives a decorative effect, It can be used as needed, such as attaching a printed label. In addition, by applying a rubber-based coating on the surface of the container, it is possible to improve the feeling of handling and to add a slip prevention effect during operation to the exterior decoration.

The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention. For example, as shown in FIGS. 6 and 7, a product shape such as a rectangular parallelepiped, a cube, a complete spherical shape (ball shape), or an oval shape may be used.
