Abstract

PURPOSE:To miniaturize a whole player, and to elevate operability by making the width of a tray, which bears a disk and conveys it to a playing position, smaller than the diameter of a depressed part. CONSTITUTION:The depressed parts 1b-1d having circular arc shaped outer circumferences capable of storing the respective disks, are formed on the disk bearing surface of the tray 1 so as to be concentric and have prescribed differences of level. The width of the tray 1 is made smaller than the diameters D1, D2 of the depressed parts 1c, 1d. Thus, space to be secured in a player housing 2 for the movement of the tray 1 comes smaller, and the miniaturization of the whole player can be attained.

Description

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

BACKGROUND ART FIG. 2 shows a conventional autoloading disc player. As shown in the figure, a tray 101 is provided so as to protrude from and be housed in a player housing 102 via a guide rail 103, and discs 104 and 105 are placed on this tray 101 and transported to a playing position. Also,
Although not shown, 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 disc player that achieves overall miniaturization and cost reduction, has a large degree of freedom in design within the player housing, and has an automatic loading disc player with good operability. To provide a loading disc player.

The autoloading disc player according to the present invention comprises:
The player has a tray that protrudes from the player housing and is freely retractable and is formed with a disk-accommodating circular arc outer circumferential recess, and that carries the disk in the recess and transports it to a playing position, and the width of the tray is smaller than the diameter of the recess. It is characterized by the fact that

Embodiments Hereinafter, an autoloading disc 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 discs 4, 5 and 6 can be placed on this tray 1. It is placed and transported to the performance position. The disks 4 and 5 have diameters of 30 cm and 20 cm, respectively, and the other disk 6 is a compact disk with a diameter of about 12 mm. In order to move the tray 1, a rack portion 1a is provided on the tray 1 along the direction of movement and along substantially the entire length, and a gear 8 meshing with the rack portion can be rotationally driven by a motor (not shown) or the like. It will be done.

Concave portions 1b to 1d each having an arcuate outer periphery and capable of accommodating each of the above-mentioned disks are formed concentrically and with a predetermined step difference on the disk supporting surface of the tray 1. The width B of the tray 1 is smaller than the diameters of the recesses 1c and 1d, and Dl.

A turntable 9 is provided within the player housing 2 with its disk supporting surface facing downward.
Each disc supported by the tray 1 and housed in the player housing 2 in a direction parallel to the disc supporting surface of the turntable 9 is located directly below the disc supporting surface of the turntable 9 with a predetermined gap therebetween. The disc that has reached just below the turntable 9 is lifted upward by the disc clamp mechanism 10 and placed on the tray 1.
It is spaced apart from above and clamped against the disk carrying surface of the turntable 9.

The disc clamp mechanism 10 includes a disc-shaped suppressing member 11 that contacts the disc and presses it against the disc supporting surface of the turntable 9, and a support pin 12 that is configured to press the disc in the vertical direction, that is, against the disc supporting surface of the turntable 9. a support member 12 that is swingably provided in a direction perpendicular to the support member 12 and rotatably supports the pressing member 11 at its free end;
Driving means (not shown) for swinging this support member 12
It consists of 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 disc is smaller than the diameter D2 of the arcuate outer peripheral recess 1c that accommodates the disc 5 with a diameter of about 20 cm, and it accommodates the compact disc 6 with a diameter of about 12 cm. recess 1d
However, the width B of the tray 1 is not limited to this configuration, and the width B of the tray 1 may be smaller than the diameter D3. Also,
This width B may be larger than Dl and smaller than Dl.

Effects of the Invention As detailed above, in the autoloading disc player according to the present invention, an arcuate outer periphery recess is formed to accommodate the disc and can protrude from the player housing, and the disc is supported in the recess and transported to the playing position. 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 disk placed on the tray protrudes from the tray in the radial direction.
When the tray protrudes outside the player housing, it is easy to grip the disc, improving operability.
