DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk cartridge storage device, and more particularly to a disk cartridge storage device for storing a disk cartridge such as a magneto-optical disk in a detachable manner.

[0002]

2. Description of the Related Art Conventionally, this type of disk cartridge storage device is used for the purpose of preventing a tape cassette (or disk cartridge) from being damaged on a storage rack side. For example, Japanese Patent Application Laid-Open No. 4-121885 discloses that a storage rack is provided with a spring mechanism with a roller, and the action of the spring mechanism with a roller prevents the tape cassette from being easily damaged when the tape cassette is inserted into or removed from the storage rack. Is described.

[0003]

However, in the above-mentioned conventional example, the structure is complicated because a space area for accommodating the spring mechanism with the roller is provided in the storage rack. However, there is a disadvantage that the cost is higher. Further, in the above conventional example, since the opposite side end surface of the roller-equipped spring mechanism comes into surface contact with the inner wall of the storage rack, the side surface of the tape cassette (or disk cartridge) is damaged by the repeated operation. Inconvenience was always occurring.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to improve the inconveniences of the above-mentioned prior art, to effectively reduce the occurrence of damage accidents on the side surface of a disk cartridge, to reduce the number of parts, to simplify the overall structure, and to reduce cost. It is an object of the present invention to provide a disk cartridge storage device in which reduction is achieved.

[0005]

According to the present invention, in order to attain the object, a plurality of stages for individually storing one or more disk cartridges having a cartridge insertion opening for inserting and removing a cartridge on one surface are provided. A storage rack having storage shelves, a leaf spring provided at the above-described cartridge insertion slot of the storage rack, and a predetermined pressing force applied to a side end surface of a disk cartridge stored at the end of the leaf spring and stored. In a disk cartridge storage device including a roller for contacting and pressing, a guide shaft which is in contact with and functions when a disk cartridge is inserted and removed is provided at a position opposite to the roller at the cartridge insertion opening of the storage rack (claim) (Invention described in Item 1)).

Therefore, according to the present invention, when the disk cartridge is inserted into the storage rack, the disk cartridge is pressed against the opposite surface by the pressing action of the plate spring provided on one side and the roller. Moving. At this time, the guide shaft attached to the cartridge insertion slot of the storage rack is inserted while the side of the disk cartridge is in linear contact, so that friction is effectively reduced compared to the conventional surface contact, and a cartridge damage accident occurs. Is reliably reduced.

Here, the cartridge insertion opening of the above-mentioned storage rack is arranged such that the end of the side wall provided with the leaf spring on the side of the cartridge insertion opening is closer to the disk cartridge insertion direction than the end of the opposite side wall. (A second aspect of the present invention). With this arrangement, when the disk cartridge is inserted, first, the leading end is guided by the roller and the guide shaft at the cartridge insertion opening of the storage rack. In such a case, the roller is in rolling contact and the guide shaft is linear. Because of the contact, the frictional force on the disk cartridge is reduced, and the operation of inserting and removing the disk cartridge is further facilitated.

Further, the roller described above may be provided at a position where it engages with a concave portion formed in advance at the side end of the disk cartridge when the disk cartridge is stored (the invention according to claim 3). . With this configuration, the disk cartridge stored in the storage rack is effectively held by the storage rack because the roller on the storage rack side engages with the concave portion of the disk cartridge.
The play of the disk cartridge is eliminated, and the generation of vibration noise is effectively prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. First, in FIGS. 1 and 2, reference numeral 1 denotes a storage rack. This storage rack 1
Has a cartridge insertion port 2 for inserting and removing a cartridge on one surface. The storage rack 1 includes a plurality of storage shelves 4, 4,... For individually storing one or more disk cartridges 3 from the cartridge insertion slot 2. A roller 5 for pressing one side end surface of the disk cartridge 3 in the direction of the other side end surface is provided in the cartridge insertion opening 2 of the storage rack 1, and a pressing force is applied to the roller 5 while holding the roller 5. And a biasing leaf spring 6.

In addition, a guide shaft 7 which is in contact with the disk cartridge 3 when the disk cartridge 3 is inserted and removed is provided at a position opposite to the roller 5 at the cartridge insertion opening 2 portion of the storage rack 1. Have been. The guide shaft 7 is located at a predetermined distance from the opening 2 in the side wall portion of the storage rack 1 opposite to the roller 5 along the direction in which the disc cartridge 3 is inserted, and the ceiling plate 1A and the floor plate 1B. Between, is interposed.

Here, the edge of the side wall portion of the cartridge insertion port 2 provided with the above-described leaf spring 6 is larger than the edge of the cartridge insertion port 2 on the guide shaft 7 side located on the opposite side. 3 is set to protrude somewhat along the insertion side.

The aforementioned roller 5 is provided with a recess 3A at a side end of the aforementioned disc cartridge 3 so as to engage when the disc cartridge 3 is stored.
(Or 3B). These recesses 3A, 3B
Are provided at the same position on the left and right toward the cartridge insertion slot 2.

Next, the operation of the embodiment shown in FIG. 1 will be described. First, when the disk cartridge 3 is inserted into the storage rack 1, the disk cartridge 3 moves while being pressed against the opposite side surface by the pressing action of the leaf spring 6 and the roller 5, as shown in FIG. At this time, the guide shaft 7 attached to the insertion opening 2 of the storage rack 1 causes the side surface of the disk cartridge 3 to come in line contact and is inserted, so that friction is reduced, and the occurrence of damage to the disk cartridge 3 is effectively reduced. Is done.

In FIG. 2B, the disk cartridge 3
In the storage rack 1 is completely stored. In this state, the roller 5 is moved to the concave portion 3A of the disk cartridge 3.
(Or 3B). For this reason, the disk cartridge 3 is held on the storage rack 1 without rattling, thereby effectively preventing generation of vibration noise and the like.

In the above embodiment, the roller 5
And the leaf spring 6 are provided on the side wall surface of the storage rack 1, so that a case or the like for storing them is not required, and the number of parts is reduced in such a point, and the entire configuration is simplified. It has become possible to reduce it.

Here, in the above embodiment, FIG. 1 shows an example in which one set of the roller 5 and the leaf spring 6 is disclosed.
, And are omitted in FIG. On the other hand, the number of the disk cartridge storage shelf 4 and the set of rollers 5 and leaf springs 6 is not limited in the present invention. For example, as shown in FIG. 5 and a leaf spring 6 may be provided.

[0017]

The present invention is constructed and functions as described above. According to this, since the rollers functioning when inserting or extracting the disk cartridge are in rolling contact and the guide shafts are in linear contact, the disk cartridge Frictional force is reduced, and the operation of insertion / removal is further facilitated. Further, since the roller is held by the leaf spring and the leaf spring is fixedly mounted on the storage case, the configuration is simplified and simplified.
It is possible to provide an unprecedented excellent disk cartridge storage device in which the number of parts is reduced and the cost can be reduced.
