Description

TECHNICAL FIELD The present invention relates to an autoloading disk player that automatically transports a disk such as a digital audio disk to a performance position and performs the performance.

BACKGROUND ART FIG. 2 shows a conventional autoloading disk player. As shown, the tray 101 is connected to the guide rail 103 relative to the player housing 102.
The discs 104 and 105 are placed on this tray 101 and transported to the performance position. Further, although not shown, a driving means for moving the tray 101 is provided.

Recesses 101a to 101c each having an arcuate outer periphery and capable of accommodating each disk are formed on the disk supporting surface of the tray 101.

SUMMARY OF THE INVENTION It is an object of the present invention to provide such an autoloading disk player that achieves overall miniaturization and cost reduction, has a large degree of freedom in design within the player housing, and has good operability. An object of the present invention is to provide an autoloading disc player.

The autoloading disc player according to the present invention has a tray that can be protruded from and stored in a player housing and has an arcuate outer circumferential recess for accommodating a disc, and that carries a disc in the recess and transports it to a playing position. It is characterized in that the width is smaller than the diameter of the recess.

Embodiments Hereinafter, an autoloading disk player as an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, a tray 1 is protruded from a player housing 2 via a pair of guide rails 3 so as to be freely stored therein. For example, three different types of disks 4, 5 and 6 can be placed on this tray 1. It is placed and transported to the performance position. In addition, disk 4
and 5 are disks with diameters of about 30 cm and 20 cm, respectively, and the other disk 6 is a compact disk with a diameter of about 12 cm. In order to move the tray 1, it is possible to provide a rack portion 1a on the tray 1 along the direction of movement and over substantially the entire length, and to drive a gear 8 that meshes with the rack portion to rotate by a motor (not shown) or the like. It will be done.

On the disk supporting surface of the tray 1, concave portions 1b to 1d having arcuate outer peripheries capable of accommodating each of the above-mentioned disks are formed concentrically and with predetermined steps. The width B of the tray 1 is the diameter of the recesses 1c and 1d.
It is smaller than D ₁ and D ₂ .

A turntable 9 is located inside the player housing 2.
is provided so that its disk supporting surface faces downward, and each disk supported on the tray 1 and housed in the player housing 2 in a direction parallel to the disk supporting surface of the turntable 9 faces downward. It is located directly below the disk carrying surface and separated by a predetermined distance. turntable 9
The disk that has reached the position directly below is lifted upward by the disk clamp mechanism 10 and separated from the tray 1, and is clamped against the disk supporting surface of the turntable 9. Note that the disk clamp mechanism 10 includes a disk-shaped pressing member 11 that comes into contact with the disk and presses it against the disk supporting surface of the turntable 9;
A support member 12 that is provided to be swingable in the vertical direction, that is, in a direction perpendicular to the disk supporting surface of the turntable 9 by means of a support pin 12, and rotatably supports the pressing member 11 at its free end, and this support member. 12 and a driving means (not shown) for swinging the shaft 12. A carriage 13 carrying an optical pickup is disposed on the support member 12, and is guided by a guide shaft 14 to move along the recording surface of a disk mounted on the turntable 9. Further, although not shown, driving means for moving the carriage 13 is provided.

In this embodiment, the width B of the tray 1 for transporting the disk is smaller than the diameter D ₂ of the arcuate outer circumferential recess 1c that accommodates the disk 5 having a diameter of about 20 cm, and the compact disk 6 having a diameter of about 12 cm.
However, the width B of the tray ₁ is not limited to this configuration.
It may be smaller than D ₃ . Also, this width B is D ₂
It may be larger than D1 and smaller than _D1 .

Effects of the Invention As described in detail above, in the autoloading disc player according to the present invention, an arcuate outer circumferential recess for storing the disc is formed so as to protrude from the player housing, and the disc is carried in the recess and moved to the playing position. It has a tray to be conveyed, and the width of the tray is smaller than the diameter of the recess (or at least one of the recesses in the case of a plurality of recesses).

Therefore, the space that must be secured within the player housing for the movement of the tray is reduced, and the player as a whole is made more compact, and the cost of materials is reduced accordingly. Furthermore, the degree of freedom in designing within the player housing is increased.

Furthermore, because of this configuration, the disc placed on the tray protrudes from the tray in the radial direction, making it easier to grab the disc when the tray protrudes outside the player housing, improving operability. be.
