The second chassis member 9120 is positioned above the second chassis member 120. In addition, the second chassis member 120 has a rotating body 420 connected to the other end of the lever member 410 is rotatably installed by a predetermined rotation means.

The rotating means is configured as follows.

A recess 214 is formed on an upper surface of the movable member 210 slidably coupled to the main slide member 200. The moving member 210 meshes with the second gear 104 which is rotated by the power of the motor 101 to move. In addition, an interlocking member 425 is rotatably supported in the main tray member 200 in which a protrusion 425a is formed in sliding contact with an upper surface of the movable member 210. The rotating body 420 is in contact with the upper surface of the interlocking member 425. Here, the rotating body 420 is elastically biased to press the upper surface of the interlocking member 425 by a torsion spring (not shown). Therefore, the protrusion 425a is elastically biased to press the upper surface. Therefore, when the protrusion 425a is interlocked with the recess 214 of the moving member 210, the rotor 420 is rotated. At this time, since the lever member 410 is rotated, the support plate 500 is moved in one direction.

On the other hand, referring to Figure 6, the stocker member 300 is provided with spring members (305, 306) for elastically pressing the upper surface of the sub-tray member (310). The spring members 305 and 306 stably hold the plurality of sub tray members 310 sequentially stacked on each other.

And the separation prevention means for preventing the separation of the plurality of sub-tray members 310 supported by the stocker member 300 is provided.

The separation preventing means has the following configuration. 2A, 2B, 2C, 6, and 12, an opening 318 for entering the turn table 151 is formed in the sub tray member 310. A first post 144 is vertically installed on the main deck 140, and a second post 409 is arranged in a line with the first post 144 on the bottom surface of the fixed plate 400. Formed.

Each free end of the first and second posts 144 and 409 maintains a space through which only one of the stacked sub-tray members 310 can pass.

However, when the sub-tray members 310 need to be fixed so as not to be separated from the stocker member 300, such as when the disc reproducing apparatus is moved, the first post 144 is upwardly moved by a predetermined driving means. By moving vertically, the interval with the second post 409 is narrowed. Accordingly, a passage through which one sub tray member 310 can pass is blocked, thereby preventing the sub tray member 310 from being separated.

The structure and operation of the first and second posts 144 and 409 will be described in more detail with reference to FIGS. 2b and 2c.

Maintain a gap where only one can pass. Accordingly, the selected sub tray member 310 may be moved to the main tray member 200 or the sub deck 150 without interference of the first and second posts 144 and 409.

On the other hand, when there is a risk that the book may be detached from the stocker member 300 by an impact from the outside, such as when moving the disc reproducing apparatus, the post member 144a of the first post 144 is raised to serve as a sub. Block the passage through which the tray member 310 can pass.

In other words, the motor member 148 is first rotated to rotate the cam gear 147 engaged with the motor member 148. Accordingly, the driving lever 145, one end of which is coupled to the pam groove 147a formed in the cam gear 147, is rotated. At this time, the drive lever 145 is rotated around the pivot shaft 146 installed on the main deck 140, and at the same time the post member of the first post 144 is coupled to the end of the drive lever 145 ( 144a is raised in the vertical direction.
