Problems solved by technology

[0009] (1) The existence of the rotation range θ of the rotating arm 209 increases its occupied space, resulting in a reduction in the efficiency of the installation space of the loading mechanism 207;
[0010] (2) As the turning range of the rotating arm 209 changes, the force acting on the bracket engaging portion 208 changes, making it difficult to move the bracket engaging portion 208 with a uniform force

Abstract

A recording and / or reproducing device for disk, comprising a disk auto changer having a disk cartridge with a plurality of trays for supporting disks, an elevator disposed on the side of the disk cartridge, and a loading mechanism (7) for pulling the trays from the disk cartridge into the elevator and returning the trays from the elevator to the disk cartridge, the loading mechanism further comprising a tray engagement part engaged with the hook parts of the trays, a belt for moving the tray engagement part in a tray loading and unloading direction, and a belt drive mechanism for running the belt, whereby the space efficiency for installation of the loading mechanism of the disk auto changer can be increased.

Description

technical field [0001] The present invention relates to a disc-shaped recording and / or reproducing device such as an automatic disc changer, and more particularly to an improved loading mechanism. Background technique [0002] known as Figure 32 As shown in the autodisc changer, this autodisc changer 201 includes a disc cartridge 204 which hierarchically contains a plurality of trays 203 on which recording media (hereinafter referred to as discs) are arranged; A lifter or lifting unit 205 opposite to the opening of the disc case 204; a movement control mechanism 206 for moving the lifter 205 up and down to the position of the selected tray 203 contained in the disc case 204; The sheet 203 is drawn from the cartridge 204 into the lifter 205 or from the lifter 205 to the loading mechanism 207 in the disc cartridge body 204 . A loading mechanism 207 is provided on the upper surface of the lifter 205 . [0003] like Figure 33 As shown, the loading m...
