Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a digital signal for recording, for example, music or video, or to support a recorded disk on a turntable and to record information on both or one side of the disk. The present invention relates to a disc player for reproducing information. Therefore, the disc player referred to in this specification includes a recording-only disc device.

[0002]

2. Description of the Related Art Conventionally, there has been a technique of placing a disk on a tray and moving the disk to a take-out / exchange position outside the apparatus or a reproduction position of a turntable.

[0003]

According to the prior art, when a tray to be moved in an L-shape from the outside to the standby position and from the standby position to the reproduction position is guided by a boss and a feed groove,
It is necessary to form an opening for releasing the boss in the feed groove by engaging a plurality of bosses in the feed groove to improve the straightness, and to move the tray in a direction substantially orthogonal to the feed groove. When the tray is moved by the guide of the boss and the feed groove, there are functional problems such that the boss is easily caught in the opening formed in the feed groove and the tray cannot be moved smoothly.

[0004]

According to the present invention, there is provided a disk player for moving a tray on which a disk is loaded in an L-shape from outside the machine to a standby position and from a standby position to a playback position in a L-shaped manner. The tray is slidably provided on the rail body by the boss and the feed groove, and each of the feed grooves is extended so as to have a different length substantially in parallel with the direction of movement of the tray outside the machine or at the standby position. Since the feed groove is formed in multiple steps and a step is provided, the tray can be supported by a plurality of bosses without opening the middle of the feed groove, and the tray can be smoothly moved to the L-shape. .
