Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk-shaped recording medium (hereinafter referred to as a disk) or a plurality of disk cartridges in which disks are accommodated. The present invention relates to a magneto-optical disk recording / reproducing apparatus capable of recording / reproducing any one of them, and particularly to a disk cartridge housing apparatus in this magneto-optical disk recording / reproducing apparatus.

[0002]

2. Description of the Related Art As an example of a disk cartridge housing device in a conventional magneto-optical disk recording / reproducing apparatus, there is a technology disclosed in Japanese Patent Laid-Open No. 6-60591. In this disclosed technology, a disc clamp made of a magnetic metal in the center of the disc cartridge is attracted by the force of a magnet, thereby pushing the disc inside the disc cartridge to one side of the disc cartridge, or attaching a spring material to the bottom of the stocker. The disk clamp is installed and the disk clamp is pressed by this spring material to eliminate the play of the disk inside the disk cartridge.

[0003]

However, the attraction structure of the disk clamp by the magnet or the pressing structure of the disk clamp by the spring material needs to be configured in the thickness direction of the disk cartridge, and a plurality of disk cartridges are stacked. In this case, there is a problem in that the dimension in the thickness direction becomes large and it is difficult to make the device thinner.

When the rattle noise prevention mechanism is constructed by pressing the disk clamp with a spring material, the center of the disk clamp is pressed. In this case,
Since the disc clamp can move on a plane parallel to the disc clamp surface by an external force such as vibration, there is a problem that rattle noise cannot be completely removed.

The present invention has been made in view of the above problems, and its purpose is to reduce the dimension in the thickness direction of the disc cartridge so that the disc cartridge accommodating portions are stacked in a plurality of stages. Even in the case of a disc, the dimension in the thickness direction becomes small, the device can be made thinner, and the disc cartridge storage device of the magneto-optical disc recording / reproducing device can completely remove the rattling of the disc in the disc cartridge under vibration. To provide.

[0006]

In order to achieve the above object, a disk cartridge housing device of a magneto-optical disk recording / reproducing apparatus according to the present invention comprises a bottom surface part of a disk cartridge housing part for housing a disk cartridge containing a disk. An opening portion and a rattle spring mounting portion are provided on the rattle spring, and the rattle spring is configured by bending a spring wire to form a holding portion and a mounting portion. The rattle spring is attached to the rattle spring mounting portion at the mounting portion. It is characterized in that it is mounted and rises diagonally upward while the pressing portion is positioned inside the opening.

The pressing portion of the rattle spring is formed into a trapezoidal shape having a linear top end portion and a sloped portion on both sides sandwiching the top end portion by bending the spring wire, and the rattle spring is positioned in the opening. Then, it is preferable that the top end portion of the pressing portion is deviated from the center of the disc cartridge housing portion in a state of being raised obliquely upward.

[0008]

With such a structure, in the disc cartridge housing device of the magneto-optical disc recording / reproducing apparatus according to the first aspect, the dimension in the disc cartridge thickness direction becomes small. Therefore, the dimension in the thickness direction is reduced even when the disc cartridge storage parts are stacked in multiple stages,
The device can be made thinner.

In addition to the above effects, in the disk cartridge housing device of the magneto-optical disk recording / reproducing apparatus according to the second aspect, when the disk cartridge is inserted into the disk cartridge housing portion of the stocker, the rattle The trapezoidal holding part of the spring is inserted into the round hole in the center of the disc cartridge, the top end of this holding part presses against the surface of the recess in the center of the disc, and the inclined parts on both sides of the holding part are recessed. Since it comes into pressure contact with the edge portion of the disk, it is possible to suppress rattling of the disk vertically, forward and backward, and left and right, and rattle noise can be completely removed.

Moreover, since the rattle spring is mounted on the rattle spring mounting portion at its mounting portion and the pressing portion is trapezoidal, the disk cartridge can be inserted and ejected without letting the rattle spring escape. It becomes possible to operate.
