Abstract

PURPOSE:To contrive miniaturization of a reproducing device by separating a drawn tray and its upper side tray from each other under the state of the drawn tray being selected in a player main body and thus drawn from a magazine, forming a space between them and rotating a disk in this space. CONSTITUTION:The plural trays T are held movably up and down in the magazine M, and under the state that selected tray T is drawn from the magazine M in the player main body 11, the drawn tray T and its upper side tray T are made apart from each other to form the space S between them. Then the disk D on the tray T drawn in this space S is lifted up and this disk D is rotated, so that the disk D is reproduced under the state of remaining the drawn tray T and a part of the disk D in the magazine M. Consequently, a part of a disk standby position 12 and a part of a disk reproducing position 13 can be overlapped. By this method, the size of the player main body 11 can be reduced in depth and width as shorter than the conventional sizes, thus enabling a reproducing device to be contrived for miniaturization.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides a disc playback method in which a magazine containing a plurality of discs is attached to a player body, and any disc is selected and played. and its equipment.

) and video (CD-V), as well as information sources (CD-V).
- ROM), and for the purpose of continuous playback and increasing the amount of information, a playback device that can automatically exchange a plurality of disks is desired, and is now being produced in some places.

Here, a playback device that can automatically exchange discs is one in which a magazine containing a plurality of discs is attached to the player body, and the disc to be played is taken out from the magazine and played within the player body. In the conventional case, with the disc completely removed from the magazine,
It was designed to play discs.

(Problems to be Solved by the Invention) As mentioned above, conventional playback devices with a disk exchange function have a structure in which the disk to be played is completely taken out from the magazine within the main body, so the disk size is at least twice the diameter of the disk. The above dimensions are necessary for the depth and width of the player body, which results in an increase in size, which goes against the trend toward miniaturization of this type of disc playback device, including car audio devices.

The present invention has been made in view of these points, and aims to downsize a disc playback device having a disc exchange function.
