  Next, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention. It should be noted that in the drawing, illustration of parts not related to the description may be omitted.

  As shown in FIG. 1, a music box device 10 according to an embodiment of the present invention has a space S formed therein and an opening at the front. In the space S, a music box movement OM (see FIGS. 2 and 6) is arranged.

  Specifically, as shown in FIGS. 1 to 7, the music box device 10 includes a rear plate 12, a lower plate 14, an upper plate 16, a left plate 18L, a right plate 18R, and a connecting member 20 (see FIGS. 2 and 6). , A base plate 22 and a music box movement OM.

As shown in FIG. 7, the rear plate 12 is a plate-like member that is long in the lateral direction. A screw hole 121 is formed in the rear plate 12 as shown in FIG. A stopper 30 is inserted into the screw hole 121 in order to stop the operation of the music box movement OM. The stopper 30 has a handle 302 formed with a male screw and a pin 304 extending from the handle 302.
As shown in FIG. 4, protrusions 122a and 122b are formed at the upper end and the lower end of the rear plate 12, respectively. The protrusions 122a and 122b are inserted into the groove 142 and the groove 162 extending in the left-right direction respectively formed on the lower plate 14 and the upper plate 16, and the rear plate 12 is slid to the right side (see the arrow shown in FIG. 7). Can be removed.

The lower plate 14 extends from the rear plate 12 to the front side, and is a plate-like member disposed on the lower side as shown in FIG. An end 144 on the front side of the lower plate 14 is curved and protrudes from the left plate 18L and the right plate 18R, and the width of the end 144 becomes smaller toward the front.
As shown in FIG. 3, leg members 54 are respectively attached to the corners of the lower surface of the lower plate 14. Of the four leg members 54, at least one is an adjuster.

The upper plate 16 is a plate-like member that extends forward from the rear plate 12 and is disposed on the upper side as shown in FIG. The front end 164 of the upper plate 16 is curved and protrudes from the left side plate 18L and the right side plate 18R, and the width of the end portion 164 becomes smaller toward the front.
Note that it is preferable that the front side end portions 144 and 164 of the upper side plate 16 and the lower side plate 14 protrude and the widths of the end portions 144 and 164 become smaller toward the front side, but the upper side plate 16 and the lower side plate 14 are reduced. Of these, only one of the front end portions may protrude, and the width of the end portion may be reduced toward the front.

The right side plate (an example of the first side plate) 18R is a plate-like member that extends from the rear plate 12 to the front side and is arranged on the right side (one side portion) when viewed from the front.
The left side plate (an example of the second side plate) 18L is a plate-like member that extends from the rear plate 12 to the front side and is arranged on the left side (the other side portion) when viewed from the front.
The adjacent lower side plate 14, upper side plate 16, left side plate 18L and right side plate 18R are preferably joined together. The sound quality is stabilized by being joined together.

As shown in FIG. 6, the connecting member 20 is a columnar member that connects the lower plate 14 and the upper plate 16. When the connecting member 20 connects the lower plate 14 and the upper plate 16, the acoustic effect is improved.
Note that the rear plate 12, the lower plate 14, the upper plate 16, the left plate 18L, the right plate 18R, and the connecting member 20 are preferably made of the same kind of wood.

The music box movement OM is a machine part for performing. The music box movement OM has a cylinder, a comb tooth, a spring, and the like. As shown in FIG. 2, the music box movement OM is disposed between the connecting member 20 and the rear plate 12 in plan view. The music box movement OM is placed on the base plate 22, and the base plate 22 is fixed to the lower plate 14 by wooden screws 50 shown in FIG. That is, the music box movement OM is fixed to the lower plate 14 via the base plate 22. The base plate 22 is preferably made of harder wood than the lower plate 14.
In the music box movement OM, when the stopper 30 is screwed into the screw hole formed in the rear plate 12, the pin 304 advances and the performance (operation) stops.

Next, a method for using the music box apparatus 10 will be described.
The music of the music box device 10 is played by winding the mainspring using the handle 52 shown in FIG. When the stopper 30 is screwed and the pin 304 is advanced toward the inside, the pin 304 comes into contact with the drive unit of the music box movement OM and the music box performance is stopped.

  The music box movement OM of the music box device 10 can be exchanged. The procedure for exchanging the music box movement OM is as follows.

(Step S1)
The rear plate 12 is slid rightward (in the direction of the arrow shown in FIG. 7) when viewed from the back side and removed (see FIG. 8).

(Step S2)
The screw 50 is removed, and the music box movement OM is removed from the lower plate 14 together with the base plate 22.

(Step S3)
