As a first means for solving the above problems, a disk cartridge accommodating a disk and a stocker having a plurality of shelves partitioned by a partition member for accommodating a plurality of the disk cartridges are provided. The partition member is provided with an elastic member which can be engaged and disengaged with a center hole of the disk and the disk cartridge, and the elastic member is formed of a cantilever plate spring, and a free end side of the plate spring is provided. A rotatable displacement member for engaging the disk and the disk cartridge in the center hole, holding the disk cartridge by the elastic member, and releasing the engagement of the disk cartridge by the elastic member. the releasing means having provided, said displacement member is rotated to displace the free end of the elastic member Has a configuration which is adapted disengage said elastic member with respect to the disc cartridge.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
The holding structure of the disk cartridge in the 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 the disk cartridge in the stocker of the present invention, and FIG. FIG. 3 is an enlarged sectional view of a main part showing a holding state of the disk cartridge in the stocker of the present invention, and FIG. 3 is an enlarged sectional view of a main part showing a holding state of the disk cartridge in the stocker of the present invention. FIG. 4 is an enlarged cross-sectional view of a main part showing a released state of holding the disk cartridge.
[0007]
Next, the holding structure of the disk cartridge in the stocker of the present invention will be described with reference to FIGS. 1 to 4. The stocker 1 is composed of a plurality of plate-shaped partition members 2 arranged at intervals. A shelf 3 is formed between them.
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 formed of a leaf spring made of a metal plate includes an arcuate elastic portion 4a, a pair of support portions 4b provided by being bent from one side of the elastic portion 4a, and one end of the elastic portion 4a. And an engaging portion 4c formed by bending downward.
[0008]
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.
The coil spring 6 is attached to the column 5, and 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 engaging portion 4c of the elastic member 4 so that the elastic member 4 rotates.
[0009]
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 disc 11 has a recording medium section 12 and a cup-shaped metal body 13 provided at the center. When the disc 11 is stored in the disc cartridge 10, the cup-shaped metal body 13 is placed in the center hole. 10b.
[0010]
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 distal end 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, the elastic portion 4a of the elastic member 4 protrudes into the center hole 10b by its own elasticity and the coil spring 6, as shown in FIG. Abut.
The elastic portion 4a presses the disk cartridge 10 against the partition member 2 located at the upper portion, and also presses the disk 11 against the inner surface of the upper wall of the disk cartridge 10, thereby holding the disk cartridge 10. .
[0011]
When the disk 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 to rotate the elastic member 4 against the coil spring 6, and the disk cartridge 10 of the elastic portion 4a Elastic pressure 11 and the engagement are released.
Thereafter, after the disk cartridge 10 is transported in the direction of arrow B by the transport means (not shown), the displacement member 8 and the elastic member 4 return to the state shown in FIG. 3 again.
In this way, holding and releasing of the disk cartridge 10 in the stocker 1 are performed.
[0012]
【The invention's effect】
The holding structure of the disk cartridge in the stocker of the present invention is such that the elastic member 4 is provided on the partition member 2, 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 so that 4, the disk cartridge 10 is held, so that the number of parts is smaller than in the past, and a disk cartridge holding structure in an inexpensive stocker can be provided.
Further, the elastic member 4 is formed 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 construction is simple, the productivity is good, and the stocker is inexpensive. And a disk cartridge holding structure can be provided.
[0013]
Further, since the releasing 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 disk cartridge holding structure 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.
