Abstract

PURPOSE:To prevent operation stop by contact of disks with the wall members between disk housing grooves at the time of reentry of the disk by forming the radius in the side view of the front end guide parts of wall members for partitioning the disk larger than that of the disk diameter. CONSTITUTION:A tray body 5a has the grooves 8 for housing the disks, a projection 7 for detecting a sensor at its front part, bosses 13a for fixing a front rear surface reference plate in the lower part near the rear end and shaft grooves 14a near the front side on the right and left of the side faces. A tray body 5c has the grooves 8 for housing the disks on its front surface and rising surface, shaft holes 14c near the upper side on the right and left side faces and rear part reference plate fixing bosses 13c near the lower side of the rear part. The radius in the side view of the side faces of the guide parts 15 at the front end of the wall members for partitioning the disks is formed larger than the radius of the compact disks 9. As a result, the interference with the front ends of the wall members at the time of reentry of the compact disks is prevented even if there are dimensional errors in the tray bodies when the tray bodies are assembled. The flawing and collision of the signal surfaces, the operation stop, etc., are thus prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc tray that is used in an apparatus or the like suitable for storing a circular disc such as a compact disc.

[0002]

2. Description of the Related Art So-called compact discs are widely used as a medium for recording and holding sounds in sound reproducing devices such as audio devices and OA devices. In addition, as a sound reproducing device, there is a device such as a so-called jukebox or a karaoke device which selects and reproduces one song from various types of songs. In this type of reproducing apparatus, a so-called disc autochanger device is generally used. This disc autochanger device stores a large number of compact discs in a predetermined storage location in advance, and selects one of them when necessary and sends it to a playback device to reproduce sound. Is. This disc autochanger device requires a storage device for storing a large number of compact discs, for example, 20 to 100 discs, that is, a disc tray.

As a disc tray as described above, conventionally,
The one disclosed in JP-A-60-111545 is known. This disc tray is formed with a large number of grooves for accommodating compact discs by integral molding such as injection molding. However, since it is difficult to form a small groove width in this disc tray, the groove width is considerably wide. For this reason, the compact disc housed in the groove may be greatly shaken to damage the signal recording surface. Also,
There is a problem that the die becomes complicated and the manufacturing cost becomes very high.

In order to solve the above-mentioned problems, the applicant of the present invention divides a tray block having a plurality of disk storage grooves in the width direction into front and rear halves to form a front and rear disk storage groove for one disk. Disc trays have been proposed. (For example, Japanese Patent Application No. 5-166657) According to this disc tray, the height of the wall member can be made low and the groove width can be made narrower, and the die structure is simpler than the integral molding, and the cost can be reduced. It is lower than stacking a large number of thin wall members one after another. However, in this type of disc tray in which the front and rear divided tray bodies are connected, a process of passing from the front tray body to the rear tray body is essential when storing the disc,
Even if the dimensional error of each tray main body is not so large, there is a problem that a large error occurs in the overall size, particularly in the width direction, when a plurality of tray main bodies are connected.

Generally, in a disc autochanger device, a desired groove position of a large number of disc storage grooves arranged in the width direction is detected by a sensor,
The work of carrying the pickup device there and pulling out one compact disc in the groove is performed. In addition, at the time of putting it back in, the work of putting the compact disk back in the groove is performed in the same manner. At this time, if there is a large error in the positions of the grooves in the front and rear tray bodies, the compact disc cannot be put in and out accurately. In particular, the compact disc hits the upper surfaces of the wall members on both sides of the desired groove position of the rear tray body, and the compact disc cannot be put back in.

[0006]

DISCLOSURE OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems in the conventional disc tray, and the tray main body in which a plurality of disc accommodating grooves are consecutively arranged has a front-back direction. Is divided into multiple blocks,
In a disc tray that is independently fixed or slidably assembled, it is an object of the present invention to prevent the disc from hitting the tip of the wall member between the storage grooves of the disc and being deactivated when the compact disc is put in and out. To do.

[0007]

DISCLOSURE OF THE INVENTION In a disc tray according to the present invention, a tray main body in which a plurality of disc storage grooves for individually storing a plurality of discs are continuously provided is divided into a plurality of blocks in the front-rear direction, each of which is divided into a plurality of blocks. In a disc tray assembled independently so as to be fixed or slidable, a disc tray in which a side view radius of a guide portion at a tip of a wall member between disc storage grooves of a rear tray body of the tray body is larger than a radius of the disc. is there. Further, a tray body, in which a plurality of disc storage grooves for individually storing a plurality of discs are continuously provided, is divided into a plurality of blocks in the front-rear direction, and each disc is independently fixed or slidably assembled. In the tray, a chamfered guide portion is also provided at a corner portion of the tray body at the tip of the wall member of the rear tray body that comes into contact with the outer circumference of the disc.

[0008]

In the disc tray of the present invention, the tray body is divided into blocks in the front-rear direction, and disc storage grooves and wall members are alternately arranged on the upper surface of each block. When the compact disc is played, it is first returned to the front tray body and moved backward. After that, it rolls into the disc storage groove of the rear tray body. At this time, since the side view radius of the tip of the disk storage wall member of the rear tray main body is larger than the radius of the compact disk, the compact disk may make an arc contact with the tip of the wall member or two or more simultaneous contacts at the time of putting in and out. Without fail, it always hits the guide part at one point and smoothly fits in the disc storage groove between the wall members.
