Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a storage case for an MD cartridge (mini disk cartridge).

[0002]

2. Description of the Related Art A conventional MD cartridge is formed in a thin box shape as shown in FIG. 4, and the left and right side surfaces of the storage section (9) are provided on the left and right side surfaces or on the left and right side surfaces of the cartridge. Provided recess (corresponding to recess 8 in FIG. 1)
The spring piece (1
0) is provided at the back of the storage part.

[0003]

Therefore, in the case of the related art, the cartridge can be stored from the front, back, front and back. This seems convenient at first, but take the cartridge out of the storage case and MD
This is troublesome when the recording / playback device is mounted, and it is necessary to check in which direction the cartridge that is picked up is facing and to retake it in the correct insertion direction. Especially when used in the car by the driver, the above operation is very dangerous and has a problem in safety.

Therefore, the main object of the present invention is to provide a storage case that can be stored only when the disk cartridge is oriented in a predetermined plane and direction, and thereby to solve the above conventional problems. To do.

[0005]

In order to achieve the above object, the present invention takes the following technical means. That is, in the storage case according to the present invention, the left and right side surfaces (5), the groove (6), (6) formed along the insertion direction at a position offset to the upper or lower side at one end portion Disc cartridge having
(7) and a case for accommodating the disc cartridge (7)
(1), the upper and lower heights of the storage portion of the case (1) are formed to have a size capable of storing the disk cartridge (7) without rattling, and the left and right side walls (2), (2) of the case (1). Grooves (6) of the disk cartridge on the inner surface, convex pieces (3) for preventing insertion error that fit into (6), and spring pieces (4) that elastically press the side surface of the disk cartridge (7). , (4) are provided.

[0006]

[Function] In the storage case (1) configured as described above, the grooves (6) and (6) of the disk cartridge (7) are provided with protrusions (3) and (3) for preventing incorrect insertion in the case. The disc cartridge (7) can be stored in the storage case (1) only when the above condition is met. Therefore, the disc cartridge (7) is always housed in the case (1) so as to face the predetermined plane and direction, and the MD cartridge taken out from the case (1) at the time of use can be used for MD reproduction without confirming its direction. It can be attached to a device, and the operation can be simplified.

[0007]

Embodiments of the present invention will be described below with reference to the embodiments shown in the drawings. 1 to 3, reference numeral (1) is MD
A storage case for storing the cartridge (7), which includes a storage portion (2) integrally molded of a synthetic resin material and having one end opened. The upper and lower heights of the storage portion (2) are formed so that the MD cartridge (7) can be stored without rattling. Also, the MD cartridge (7)
The right and left side surfaces (5), (5) are provided with grooves (6), (6) along one side of the one end portion, which are offset upward or downward along the insertion direction.

Also, the left and right side walls (2) of the storage case (1),
On the inner surface of the inner part of (2), the protrusions (3) and (3) for preventing mis-insertion that fit in the grooves (6) and (6) of the MD cartridge, and the inserted MD
Spring pieces (4), (4) that elastically engage with the recess (8) provided on the side surface of the cartridge (7) to eliminate rattling in the left-right direction.
Are provided.

In the storage case (1) constructed as described above, the grooves (6) and (6) of the MD cartridge (7) are provided with the protrusions (3) and (3) for preventing erroneous insertion in the case. The MD cartridge (7) can be stored in the storage case (1) only when it is inserted in the predetermined direction, that is, when the MD cartridge (7) is inserted upside down or in the reverse direction. In this case, the MD cartridge (7) cannot be completely stored by hitting the erroneous insertion preventing convex pieces (3) and (3). Therefore, M
The D cartridge (7) is always housed in the case (1) so as to face the predetermined plane and direction, so that the MD cartridge taken out from the case (1) during use can be used in an MD playback device without confirming its direction. Can be installed.

Although the embodiments considered to be representative of the present invention have been described above, the present invention is not necessarily limited to the structures of these embodiments. For example, the cartridge is not limited to the MD cartridge, but can be applied to an optical disk cartridge and other cartridges as long as it has the above-mentioned grooves (6) and (6) on the side surface. In addition, the present invention can be implemented by appropriately modifying it within the scope of providing the constituent elements, achieving the object of the present invention, and achieving the following effects.

[0011]

As described above, in the storage case of the present invention, the cartridge can be stored in the storage case only when the groove of the disk cartridge is aligned with the projection for preventing the incorrect insertion in the case. The disk cartridge can be housed in the housing case so as to face the predetermined plane and direction. As a result, the cartridge taken out from the case at the time of use can be installed in the playback device without checking the direction and surface of the cartridge, which simplifies the handling operation and reduces the risk of in-vehicle handling. Since the erroneous insertion preventing convex piece can be integrally formed with the case body by synthetic molding, it can be manufactured at the same price as the conventional case.
