Abstract

PURPOSE:To easily load and unload a disk by providing a recessed part where the disk is loaded and a lock part which clamps the disk radially. CONSTITUTION:The recessed part 7 having nearly the same diameter as the external diameter of the disk is formed in the storage tray 6 molded out of a resin material and a step is formed of a slight projection part 8 provided to the outer peripheral part. This part corresponds to the outermost peripheral part of the disk and is formed only at the part which contacts a part where no signal is recorded. Further, four lock parts 9-12 which have elasticity and press the outer periphery of the disk toward the center of the disk are provided at positions symmetrical about the face direction of the disk, and claws 9a-11a which are pressed in pushing and spreading the lock parts 9-12 along slanting parts during loading and have revers tilt angles for clamping the disk completely when moving beyond the constant slanting parts are formed atop of the lock parts 9-12. Consequently, the disk is easily taken out of and put in the tray by applying one finger each between the lock parts 9 and 10, and 11 and 12.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a disc storage tray used in an optical disc system or the like in which digital signals are recorded at high density on information tracks of a disc-shaped recording medium. .

Conventional Structure and Problems Generally, this type of disc storage tray is used for video discs that record video signals and digital audio discs that record encoded audio signals, as well as for other combinations.・−.

It is applied to high-density information recording and reproducing discs for computers and the like.

In this system, coded video signals, audio signals, and various other information are recorded as information tracks on a disk, and while the disk is rotating at high speed, light emitted from a light source such as a laser beam is used to track the information on the disk. By focusing the light on the disk and reading the reflected light from the disk surface,
It reproduces the original recorded information.

This optical information reading device can record information at an extremely high density, and has the advantage of being able to record information at a higher density, with higher accuracy, and with higher performance than conventional analog systems.

However, these discs on which information is recorded with high density are made of resin materials such as acrylic or polycarbonate, and if the disc surface becomes scratched or has fingerprints on it, the performance may deteriorate significantly or the disc may become unplayable. Because of this, a storage tray to protect the discs is required.

3.\-7 The conventional storage tray will be explained below using a compact disc as an example.

Figure 1 shows a conventional storage tray and disk with a diameter of 1201 mm.
A disk 1 with a hole diameter of 151,111 mm and a thickness of 1.2 mm is manufactured by press-fitting the center hole 4 of the disk into a locking part 3 having spring properties formed near the center of a storage tray 2 molded from a resin material. can be stored. The disc 1 is slightly suspended on a part of the outer periphery of this locking part,
The convex portion 5 is formed so that the surface of the storage tray 2 does not come into direct contact with the disk surface.

However, with the above conventional configuration, when inserting the disc into the storage tray with your fingers, it is necessary to press the center of the disc with your finger, and when removing the disc,
Normally, only the outer periphery of the disc is lifted, but
Since the periphery of the disc warps and becomes difficult to remove, it is actually necessary to press the central part of the locking part 3 of the storage tray with your fingertips to weaken the springiness of the disc against the hole 4 while removing the disc. However, there is a problem in that it is difficult to attach and detach the disk.

There is also the problem that the disk may be damaged or stained due to incorrect operation when attaching or detaching the disk.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned problems of the conventional art, and an object of the present invention is to provide a disk storage tray that has a simple structure and allows disks to be attached and detached with simple operations.

Structure of the Invention The present invention is a storage tray that includes a recess into which a disk can be mounted and a locking portion that clamps the disk in the radial direction.
The disk can be easily attached and detached using two fingers.

Description of examples FIG. 2 shows an embodiment of the present invention.

In FIG. 2, a storage tray 6 molded from a resin material is formed with a recess 7 that can accommodate a disc and has approximately the same diameter as the outer diameter of the disc, and at the same time, it is possible to prevent the surface of the disc from coming into contact with the surface of the recess. 6. In order to avoid bending, a step is provided by a slight convex portion 8 provided on the outer periphery. This portion corresponds to the outermost circumferential portion of the disk, and is formed only in the portion that contacts the portion of the disk where no signals are recorded.

Further, four locking portions 9, 10, 11, and 12 having spring properties that press the outer periphery of the disk toward the center are provided at mutually symmetrical positions in the surface direction of the disk. Also, at the tip of each of the locking parts 9 to 12, when installing, push the locking parts 9 to 12 apart along the sloped part, and when the disc is over a certain slope, the disc can be completely clamped. The claws 9a to 11a are formed with opposite inclination angles.

In this way, between the locking parts 9 and 10 and between the locking parts 11 and 1
Since the spaces between the discs 2 and 2 are formed at symmetrical positions and separated from each other, place one finger between each of the locking parts 9 and 10 and between 11 and 12, pinch the outer periphery of the disc, and pull it up. As a result, the disc can be easily removed from the tray, and the disc can be easily stored in the tray by performing the reverse operation. For this purpose, it goes without saying that it is desirable that the shape of the concave portion 7 of the tray between each of the locking portions 9 and 10 and between 11 and 12 be formed to be slightly smaller than the outermost diameter of the disk.

Furthermore, the hole 13 provided in the center of the recess 7 of the tray is unnecessary for the purpose of simply storing a disc;
As a special case, when the disc is mounted on the playback player while still being mounted on the storage tray, the disc can be clamped through this hole and used to rotate the disc directly on the turntable.

Effects of the Invention As described above, according to the present invention, there are two holes in the recess of the storage tray.
You can easily attach and detach the disk without any wobbling by simply picking up the outer circumference of the disk with two fingers.
