However, according to the above-mentioned conventional disk holder, there is a problem that the size of the disk player cannot be reduced. In other words, when the optical disc is reproduced, the disc is rotated while being completely ejected from the disc holder. Therefore, the disc player device needs a storage width of the disc holder and a width for reproducing the optical disc. Therefore, the width of the disc player device cannot be less than twice the diameter of the optical disc, and there is a limit to miniaturization.

[0006] If only a part of the optical disk is ejected from the disk holder for reproduction, the optical disk hits the partition plate to cause damage or defective reproduction.

The present invention has been made in view of the above circumstances, and an object of the present invention is to improve the size of a disc player by improving a disc holder.

[0008]

According to the present invention, there is provided a disk holder detachably mounted on a disk player apparatus for playing back an optical disk, the disk holder having an opening and having the opening. Including a holder main body in which a type disk can be taken in and out, and partition plates provided at equal intervals in the holder main body, a space between each of the partition plates serving as a disk storage portion for storing an optical disk, Each of the partition plates is cut out in a discharge direction of the optical disk stored in the disk storage unit, and the holder main body has at least one of a flat portion and a bottom surface parallel to the optical disk stored in the disk storage portion. It is another object of the present invention to provide a disc holder characterized in that the opening side can be freely opened and closed.

The present invention also relates to a disc holder detachably mounted on a disc player apparatus for playing back an optical disc, wherein the holder has an opening so that the optical disc can be taken in and out. A disk holder comprising: a main body; and insertion guides projecting from both side surfaces of the holder main body so as to face each other, and the insertion guides support both ends of the optical disc. Is what you do. In particular, in this disc holder, at least one of the flat portion and the bottom portion of the holder main body parallel to the optical disc housed therein is openable and closable on the opening side.

In particular, in the flat portion 11b parallel to the stored optical disk d, the opening 15 is openable and closable. Specifically, the opening 15 in the plane portion 11b is cut out, and a door 19 that can be opened and closed is mounted here. The door 19 employs a resin hinge or a hinge at a bent portion thereof, but may be configured to be opened and closed by sliding the entire flat portion 11b back and forth.

On the other hand, the partition plates 13 are also made of synthetic resin or the like, like the holder body 11, and are arranged in parallel with the flat portion 11b and the bottom surface portion 11c of the holder body 11, and about five sheets are provided. Are formed as disk storage portions 16a, 16b,... For storing the optical disk d. Thereby, the optical disk d is provided between the partition plates 13 (disk storage sections 16a, 16b,...).
Can be stored separately from each other.

Incidentally, reference numeral 18 denotes a stored optical disk d.
And 17 are pressing pieces for discharging the optical disc d held by the leaf spring 18 to the outside.
The pressing piece 17 protrudes from the rear surface 11 d of the holder body 11. In particular, the pressing pieces 17 are arranged one by one in each of the disk storage sections 16a, 16b,..., And are located in the corresponding disk storage section (for example, 16a) when a required pressing piece 17 is pressed. The optical disk d is pressed at the base end of the pressing piece 17, and is ejected to the outside (Y1 direction). Further, when the optical disk d is pushed into the disk storage portion 16, both side edges thereof are pressed and held by the leaf spring 18.

Here, the partition plate 13 is notched in the ejection direction of the optical disk d, and the flat portion 11b of the holder body 11 is cut out.
And is smaller than the bottom surface 11c. This allows
The rotation and reproduction of the optical disk d are enabled while a part of the optical disk d is stored in the disk holder. In particular, the partition plate 13 is shorter than the diameter of the optical disc d,
In addition, the end face 1 of the opening 15 is formed longer than the radius.
The partition plate 13 does not exist from 5a to the vicinity of the center of the optical disk d. That is, the partition plate 1
3, only approximately half (preferably more than half) of the optical disk d is supported on the far side.

Next, another embodiment of the present invention will be described with reference to FIGS. The same portions as those of the disk holder 10 are denoted by the same reference numerals, and description thereof will be omitted.

4 and 5, reference numeral 20 denotes a disk holder according to the present invention; 23, an insertion guide which protrudes from the center of both side surfaces 11a, 11a in the holder body 11 in place of the partition plate; Is the holder body 1
1 is a support guide provided on the back surface portion 11d, and the respective insertion guides 23 and support guides 25 are provided at equal intervals as shown in FIG. 5, and a disk housing in which one optical disk d is stored therebetween. The parts 16a, 16b, ... are formed. The optical disk d is supported at both ends at the center by an insertion guide 23 and at the rear edge by a support guide 25.

The insertion guide 23 is attached to the holder body 1.
1 is not limited to projecting from the center of both side portions 11a, 11a.
From the center to the back surface 11d, or may extend to the end surface 15a of the opening 15. Also in this example, it is preferable that the flat portion 11b of the holder body 11 can be opened and closed similarly to the disk holder 10.

Next, the usage of the disk holders 10, 20 according to the present invention will be described with reference to FIG. First, the disc holders 10, 20 are mounted on the disc player device p.
Is mounted by being inserted along the arrow Y2 direction. Then, when the load button of the desired disk d is pressed, the pressing piece 17 at the required location is pressed, and the desired optical disk d is ejected from the disk storage unit 16.

Thereafter, the optical disk d is sandwiched by a delivery roller r, which is driven to rotate, and a vertically movable support base m.
Is pulled out until the disc hole h fits into the turntable t placed on the disk (delivery state e).

The optical disc d set on the turntable t reads music information while being rotated by a pickup g (movable in the direction of arrow Y3) mounted on a support table m.

In the ejection direction of the optical disk d,
Since the partition plate 13 and the insertion guide 23 are not present, the optical disc d can be reproduced in a state where a part of the optical disc d is stored in the disc holders 10 and 20 as shown in the delivery state e of FIG. As a result, the width L of the disc player device p can be reduced, and the size of the disc player device p can be reduced. In particular, the insertion guide 23
Can be formed with extremely small projections, so that the disc holder 20 can be made thinner and, consequently, the disc player device p can be made thinner.

Here, the optical disk d is assumed to be a compact disk on which music information is recorded, but it goes without saying that a video disk or the like on which video information or the like is recorded may be used.
