DESCRIPTION OF THE PREFERRED EMBODIMENTS The holding structure of a disk cartridge in a stocker of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is a side view of the holding structure of a disk cartridge in a stocker of the present invention, and FIG. FIG. 3 is a bottom view of the holding structure of the disk cartridge in the stocker of the present invention, FIG. 3 is an enlarged sectional view of a main part showing the holding state of the disk cartridge in the stocker of the present invention, and FIG. FIG. 6 is an enlarged cross-sectional view of a main part showing a released state of holding the disk cartridge in the disk cartridge holding structure in FIG.

Next, the holding structure of the disk cartridge in the stocker according to the present invention will be described with reference to FIGS. 1 to 4. The stocker 1 is constituted by a plurality of plate-like partition members 2 arranged at intervals. A shelf 3 is formed between the partition members 2. Further, the partition member 2 is formed of a synthetic resin molded product, and has a hole 2a provided at the center and a notch 2b provided at the lower surface. The elastic member 4 made of a leaf spring made of a metal plate includes an arcuate elastic portion 4a,
It has a pair of support parts 4b provided by bending from the side of one end of the elastic part 4a, and an engaging part 4c formed by bending downward from one end of the elastic part 4a.

The elastic member 4 is disposed in the hole 2a of the partition member 2, and is rotatably attached to the partition member 2 by a column 5 so that the elastic member 4 is cantilevered. ing. Further, the coil spring 6 is
The elastic member 4 is constantly urged by the coil spring 6 so that the elastic portion 4a always rotates in the direction of the shelf 3. The release means 7 has a displacement member 8 made of a metal plate or the like. The displacement member 8 is disposed in a notch 2b provided on the lower surface of the partition member 2, and the displacement member 8 is 9 so as to be rotatable. When the displacement member 8 is attached, one end of the displacement member 8 can be disengaged from the engagement portion 4c of the elastic member 4,
The elastic member 4 is rotated.

The disk cartridge 10 made of a box-shaped synthetic resin has a center hole 10b provided in the center of a lower wall 10a, and a disk 11 is accommodated in the disk cartridge 10. The disk 11 has a recording medium unit 12 and a cup-shaped metal body 13 provided at the center. When the disk 11 is stored in the disk cartridge 10, the cup-shaped metal body 1
3 faces the center hole 10b.

The disk cartridge 10 is inserted into the shelf 3 of the stocker 1 from the direction of arrow A, and the disk cartridge 10 is stocked on each shelf 3. First, when the disk cartridge 10 is inserted into the shelf 3, the elastic member 4 is turned at the tip of the disk cartridge 10 so as to enter the hole 2 a against the elasticity of the elastic portion 4 a and the coil spring 6. After the movement, as shown in FIG. 3, the elastic portion 4a of the elastic member 4 is moved by its own elasticity and the coil spring 6 into the center hole 10a.
b, the elastic portion 4a comes into contact with the edge of the center hole 10b and the metal body 13. And this elastic part 4a
As a result, the disc cartridge 10 is pressed against the partition member 2 located at the top, and the disc 11 is pressed against the inner surface of the upper wall of the disc cartridge 10,
The disk cartridge 10 is held.

When the disc cartridge 10 thus held is transported in the direction of arrow B, first, the displacement member 8 is rotated in the direction of arrow C by the release means 7. Then, as shown in FIG. 4, the displacement member 8 comes into contact with the engaging portion 4c of the elastic member 4, rotates the elastic member 4 against the coil spring 6, and the disk cartridge 10 of the elastic portion 4a.
And the disc 11 are released from the elastic pressure and engagement. Then, after the disc cartridge 10 is conveyed in the direction of arrow B by the conveying means (not shown), the displacement member 8 and the elastic member 4
Again, the state returns to the state shown in FIG. In this manner, the disc cartridge 10 is held in the stocker 1 and released.

[0012]

The disc cartridge holding structure in the stocker according to the present invention is such that the partition member 2 is provided with an elastic member 4, and the elastic member 4 is engaged with the disk 11 and the disk cartridge 10 in the center hole 10b of the disk cartridge 10. Since the disk cartridge 10 is held by the elastic member 4, the number of components is smaller than in the related art, and a disk cartridge holding structure in an inexpensive stocker can be provided. Also, the elastic member 4
Is made of a cantilevered leaf spring, and the free end side of the leaf spring is engaged with and disengaged from the disk cartridge 10. Therefore, the configuration is simple, the productivity is high, and the holding of the disk cartridge in an inexpensive stocker is achieved. Can provide structure.

Further, since the release means 7 for releasing the holding of the elastic member 4 by the engagement with the disk cartridge 10 is provided, it is possible to provide a structure for holding the disk cartridge in a stocker in which the disk cartridge 10 can be easily transported. Further, since the release means 7 is constituted by the displacement member 8 for displacing the free end side of the elastic member 4 so as to disengage the elastic member 4 from the disk cartridge 10, the structure is simple, thin, inexpensive and compact. The storage structure of the disk cartridge in the stocker can be provided.
