Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk cartridge storage case capable of storing a plurality of disk cartridges such as an optical disk, a magneto-optical disk, and a 3.5-inch micro floppy disk in a stacked state. Things.

[0002]

2. Description of the Related Art FIG. 10 shows a known disk cartridge storage case.

The above-mentioned disk cartridge storage case 10
1. A case body 102 capable of storing a plurality of disk cartridges 201...
A cover 104 for opening and closing the cartridge entrance 103 of the case body 102;

The case body 102 accommodates a plurality of disk cartridges 201... 201 with their heights aligned.

[0005] The lid 104 is connected to the case body 10.
2 is rotatably mounted on a shaft 105.

Then, from the state in which the cartridge entrance / exit 103 of the case main body 102 shown in FIGS. 10 to 11 is closed by the lid 104, the lid 104 is moved by approximately 90 ° in one direction about the shaft 105. When rotated, the cartridge entrance 103 is opened as shown in FIG. Then, the lid 104 is further rotated by approximately 90 °.
When the cover 104 is rotated, as shown in FIG.
The case main body 102 is mounted on a table or the like in a state where the case main body 102 is slightly inclined with the base as a pedestal.

[0007]

The above-described conventional disk cartridge storage case 101 has the following problems.

(1) As shown in FIG.
When placed on a table or the like with the base as a pedestal, a part of the lid 104
In order to protrude from the position 02a, a large mounting space is required, which is inconvenient for mounting in a narrow place or the like.

(2) As shown in FIG. 11, the bottom plate 102b of the case body 102 is formed flat and accommodates the disk cartridges 201. , Cartridge entrance 10
It is difficult to pick out a desired disk cartridge 201 from 3.

(3) In order to solve the problem (2), a second bottom plate is disposed on the bottom plate 102b of the case main body 102, and the second bottom plate is inclined. Although it is conceivable to lift the plurality of disk cartridges mounted thereon in a stepwise manner, if the second bottom plate is tilted at a large tilt angle, the plurality of disk cartridges mounted thereon may be lifted. Since the disk cartridge at the end of the disk cartridge may fall from the second bottom plate, the second bottom plate may be greatly inclined to form a large step between the plurality of disk cartridges. Cannot be generated.

The present invention solves the above-mentioned conventional problems and reduces the mounting space by adopting a structure in which the case main body can be housed in the lid with the cartridge entrance opened. At the same time, when the case main body is stored in the lid, the cartridge mounting plate disposed on the bottom of the case main body tilts, and the stored plural disk cartridges are projected from the cartridge entrance and exit stepwise. In particular, when the cartridge mounting plate is inclined, the width from the lower end to the upper end is made longer than before the inclination, and the inclination angle of the cartridge mounting plate is increased. Larger steps can be created between multiple disk cartridges by making them larger In which it was to be able to bet.

[0012]

According to the present invention, there is provided a case body capable of accommodating a plurality of disk cartridges in a stacked state, and the case body being rotatably and slidably attached to the case body. By rotating with respect to the main body, the cartridge doorway is opened and closed,
A lid for accommodating the case body by sliding the cartridge entrance with the case open with respect to the case body, and a first shaft at one end attached to the bottom of the case body. The cartridge mounting plate that lifts the plurality of disk cartridges mounted thereon in a stepwise manner by tilting the center of the In the disk cartridge storage case provided with a cartridge mounting plate inclining means for inclining the cartridge, the length from the lower end to the upper end of the cartridge mounting plate in the inclined state is the length in the state before the inclination. By increasing the configuration, the cartridge is placed on the cartridge mounting plate before being tilted. Without dropping the disk cartridge at the end of the cartridge mounting plate from the cartridge mounting plate, the inclination angle of the cartridge mounting plate is increased so that a plurality of disk cartridges mounted on the cartridge mounting plate In this case, a large step is generated, so that the disk cartridge can be more easily taken out.
