With this arrangement, exposed portions of the minidisk cartridge B held in the storing case A are moved forward or backward to push the cartridge B out of the case A, whereby it can be easily taken out.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a storage case for storing a mini disk cartridge such as a magnetic disk and an optical disk.

[0002]

2. Description of the Related Art In recent years, various recording media have been developed. As one of them, a mini disk cartridge is known. The mini disk is put in a plastic cartridge, and the cartridge containing the mini disk is stored in a mini disk cartridge storage case. As a conventional mini disk cartridge storage case, a so-called sleeve-shaped storage case is used.

[0003]

However, with the current sleeve-shaped storage case for mini-disc cartridges, it is difficult to remove the mini-disc cartridge from the storage case with one hand, and it is necessary to remove it with both hands.
Therefore, the conventional sleeve-shaped storage case for a mini-disc cartridge is a slot-in type in which the mini-disc cartridge is inserted into an insertion slot without opening and closing a lid when the mini-disc cartridge is taken in and out of the recording / reproducing apparatus. Not adapted to the system. In addition, when used in a car or the like, it is often taken out with one hand, and there is a problem that the current sleeve-shaped storage case for mini-disc cartridges has poor usability.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a mini disk cartridge storage which can easily be taken out of the storage case with one hand. In the case, therefore, when inserting and removing the mini-disc cartridge from the recording / reproducing machine, it is compatible with the slot-in method, which is a method for inserting the mini-disc cartridge into the insertion port without opening the lid, etc. The mini disk cartridge storage case can be inserted into the mini disk cartridge storage case from either of the front and rear directions, and can be removed from both directions of the mini disk cartridge storage case. Is to provide.

[0005]

In order to achieve the above object, a mini disk cartridge storage case according to the present invention comprises a top plate, a bottom plate, and two opposing sides of four sides from the top plate to the bottom plate. A side plate is formed on one of the side surfaces, and a notch is provided adjacent to both opening surfaces of the top plate in a quadrangular prism-shaped sleeve type mini disk cartridge storage case capable of storing a mini disk cartridge therein. The mini-disc cartridge stored inside is pushed out with both fingers in the front and rear directions of the storage case, making it easy to remove. Further, two pairs of four protrusions are provided at positions close to the two opening surfaces of the bottom plate and adjacent to the side plates, so that even if the mini disk cartridge is inserted from both the front and rear directions of the storage case for the mini disk cartridge, the fit can be achieved. The feature is that the mini-disc cartridges housed inside are prevented from falling off.

According to the present invention, there is provided a storage case for a mini-disc cartridge in which the mini-disc cartridge can be easily removed from the storage case with one hand.
When inserting or removing a mini disk cartridge from a recording / reproducing machine, it is compatible with the slot-in method, which is a method of inserting a mini disk cartridge into the insertion slot without opening the lid etc. When the mini disc cartridge is inserted into the storage case, the mini disc cartridge can be inserted from either of the front and rear directions, and the mini disc cartridge storage case can be removed from both directions of the mini disc cartridge storage case. .
