In the case of the playing hole type, the periphery of the playing hole may be deformed by an external force depending on the arrangement and carrying state of the paper bag-shaped case.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a music box disc case which can be stored without damaging the music box disc.

[0005]

In order to achieve the above object, the present invention is a music box in which a music box disc is housed in which a plurality of playing projections are formed at predetermined radial positions corresponding to the music. A case for a disc, comprising a storage section and a lid section for covering the storage section,
When the disc is stored,
The peripheral edge of the disc that is not formed and the playing projection
Touches the inside wall of the storage part
Is formed on the lid, and the disc is attached to the lid.
When the stored storage part is covered, the playing convex part is
The disc is stored in the storage part so that it is located on the side
Even if it is,
The state where the playing convex part does not hit the inner wall of the lid part
A contact portion is formed so as to contact with each other .

The music box disc case is constructed by providing a CD case with the contact portion.

According to the present invention, the storage portion and the lid portion are
Since the facing portion is provided so as to face the peripheral portion of the disc on which the playing convex portion is not formed, the playing convex portion does not come into contact with the storage portion, and the playing convex portion covers the lid even if it is mistakenly stored upside down. The music box disc can be safely stored in the music box disc case without being damaged.

FIG. 4 is a front explanatory view showing an example of the mutual positional relationship, FIG. 4 is a plan view showing the mutual positional relationship between the claw portion of the music box disc of the present embodiment and the music box valve body, and FIG. 5 is a view of the music box disc of the present embodiment. It is explanatory drawing which shows a structure.

Music box disc 1 according to the present embodiment
Is a disc-shaped music box disc 1 as shown in FIG.
A mounting hole 2 is formed at the center position of the music box, a positioning hole 3 is formed near the mounting hole 2 for positioning at the time of mounting, and in the radial direction of the music box disc 1, a valve of each scale of the music box valve body is formed. A plurality of playing projections 5 for playing a stick are formed in correspondence with playing music.

As shown in FIGS. 3 and 4, the music box disc 1 is provided with valve rods 7 of each scale, which are formed with hit portions 6a, 6b, ... The music box disc 1 is arranged with respect to the music box valve body 8, the music box disc 1 is driven to rotate about its axis, and the performance convex portion 5 formed corresponding to the musical piece tunes the ball hit portion 6a of the valve rod 7 at each scale. 6b ... are played in sequence, and the performance music is performed. Here, the valve rod 7 of each scale has the hit parts 6a, 6
In b ..., it is configured to be played only by the corresponding performance convex portion 5.

As shown in FIGS. 1 and 2, the music box disc case 20 according to the present embodiment has a storage section 1 as shown in FIG.
0 and a lid portion 11 that can be opened and closed with respect to the storage portion 10 are main constituent elements. The accommodating portion 10 is inserted into the mounting hole 2 of the music box disc 1 and has an elastic notch 13a on its peripheral surface.
A mounting bar 13 formed with and a positioning bar 14 inserted into the positioning hole 3 are formed to project. A ring-shaped contact portion 15 is formed in the storage portion 10 when the music box disc 1 is stored, the ring-shaped contact portion 15 is in contact with the peripheral edge portion of the music box disc 1 where the playing projection 5 is not formed.
On the other hand, the lid portion 11 has a ring-shaped contact portion 16 that is in contact with the peripheral edge portion of the music box disc 1 when the music box disc 1 is stored in the storage portion 10 and is rotated so as to cover the storage portion 10. Has been formed.

In order to store the music box disc 1 in the music box disc case 20 of the present embodiment having such a configuration, the mounting hole 2 is mounted with the positioning bar 14 inserted into the positioning hole 3 and positioned. When mounted on the bar 13, the elastic notch 13a bends to accommodate the music box disc 1 while being elastically held by the mounting bar 13, and the contact portion 15 forms the playing projection 5 of the music box disc 1. It will be in contact with the peripheral part that is not open. In this state, the playing convex portion 5 of the music box disc 1 does not abut the inner wall of the storage portion 10 even when stacked and transported, and the music box disc 1 is safely stored in the music box disc case 20 and the playing convex portion 5 is prevented from being damaged.

Further, the music box disc case 20
Even when the music box disc 1 is stored upside down, since the contact portion 16 is in contact with the peripheral edge portion of the music box disc 1, the playing projection 5 of the music box disc 1 hits the inner wall of the lid 11, The playing projection 5 is prevented from being damaged.

Further, in the present embodiment, the already-used CD (Compact Disk) case is used, and the contact portions 15 and 16 are provided on the case, so that it can be easily manufactured at a low manufacturing cost. Will be possible.

As described above, according to the present embodiment, the accommodating portion 10 of the music box disc case 20 has the contact portion 15 that is in contact with the peripheral edge portion of the music box disc 1 on which the playing projection 5 is not formed. Since the cover portion 11 of the music box disc case 20 is formed with the contact portion 16 that is in contact with the peripheral edge portion of the music box disc 1, the playing convex portion of the music box disc 1 housed in the music box disc case 20 is formed. 5 is a music box disc case 20
It is not damaged by carrying, stacking, dropping, etc., and can be easily manufactured at a low manufacturing cost by using the CD case.
