Abstract

PURPOSE:To simplify the handling of a disc, by supporting the outside circumferential face of the disc by a disc cassette. CONSTITUTION:The disc cassette is set on a disc player 1 so that the side of an upper case 11 is the lower side; and when a lever part 7b of a ring 7 is turned, a projection 7a of the ring 7 is struck against a lever 8 to turn the lever 8, and a supporting material 10 recedes from the outside circumference of a disc 3. At this time, the disc 3 is released from the supporting material 10 and is set on a turntable 2 of a disc player body 1, and a recording signal is read out by a pickup 4. At the play end time, when the lever part 7b is returned to the original position, a spring 9 presses the supporting material 10 to the outside circumference of the disc 3, and the disc 3 is held.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a disc cassette for storing compact discs and the like.

Figure 1 shows a conventional disc player, which has a turntable (2) formed in the center of the player body +11.
) Place the disc (31) on the turntable (2)
The signal recorded on the disk (3) is read out by rotating the pickup (41) and moving the pickup (41) radially with respect to the rotation axis.This disk (3) is normally used when not in use. It is stored in the disk case (5), and it is complicated to put in and take out the disk (3), and the surface of the disk (3) gets dirty because the disk (31) must be held directly by hand when taking it in and out.
This was a cause of interference with accurate signal reproduction.

This invention was made to solve the above-mentioned drawbacks, and the outer periphery of the disk is supported by a disk cassette, thereby simplifying the handling of the disk.

Hereinafter, this invention will be explained with reference to FIGS. 2 and 3, which are one embodiment.

In the figure, (6) is a box-shaped lower case,
A ring-shaped protrusion (6a) in the center and this protrusion (6a)
(8 bosses placed inside and outside) (6b)
(6c) and a notch (6d) formed by cutting out the outer peripheral wall. (7) is a ring that is slidably arranged between the rows of ring-shaped projections (6a) in the lower case (6), and has a projection (7a) of 3a formed on the upper surface and a lever part C7. 'r3) is formed to protrude from the cutout (6d) of the lower case (6). (8)
(9) is a lever rotatably housed in the post (6a) of the lower case (6), and (9) is a lever (8) and post (6b)
) and biases the lever (8) in a predetermined direction, (lO) is an elastically deformable support mounted on the lever (8), and eight supports (lO) 1
It is possible to hold the disc (3) in position by pressing the disc (3) outward 8 VC at an angle of 20° and supporting the disc (3) on the lever (8). (11) is the lower case (6)
At the same time, the upper case that houses these has a through hole (lla) formed in the center thereof through which the disk (3) can be inserted.

With this configuration, the disc player II is installed so that the upper case (11) side of the disc player
I, and move the lever part C7b) of the ring (7) to the second position.
When the ring (7) is rotated as shown by the dotted line in the figure, the protrusion (
7a) collides with lever (8)K and moves the lever away. At this time, since the eight supports (lO:) move as shown, the disc (3) is released from the supports (lO5) and moves onto the turntable + of the disc player body fi+.
21, and the recorded signal will be read out by the pink-up (4). Note that the disk (31 is a through hole (ll) of the upper case (11)
The turntable (2) is not limited to being taken out from the disc cassette through a), but may be constructed so that the turntable (2) enters into the disc cassette. At the end of the performance, when the lever part (7b) is returned to its original position, the spring (9) will press the support (10,) against the outer periphery of the disc (3). It becomes possible to hold.

5 and 6 show other embodiments. In FIG. 5, a groove (8a) is formed in the lever (8), and a protrusion (7a) of the ring (7) is formed in the groove (8a). The spring (9) is constructed so as to be movably engaged with the lever part (7b).

Figure 6 shows four parts (7c) on the outer circumferential surface of the ring (7).
The rear end of the lever (8) is engaged in the four parts (7c) so that the tip end thereof can be rotated, and can be operated in exactly the same way.

In addition, in the above-mentioned example, the disk (3) was configured to be held by eight supports (10), but
It is also possible to support the disc (3) at two or more points, and by driving the lever part (7b) according to the operating state of the disc player body 11+
) damage can be prevented.

As explained above, according to the present invention, it is possible to eliminate the risk of contaminating the disc, and it is also possible to easily attach and detach the disc to and from the disc player, so the practical value of the present invention is great.
