The reverse rotation of the drive motor 608 is transmitted to the gear portion 606 via the gear group 607 and moves the slide plate 210 to the inner side. Since the other slide plate 220 is connected to the slide plate 210 via the seesaw lever, it moves in the opposite direction, that is, forward.

By the movement of the slide plates 210, 220, the engagement pins 215, 225 are pushed up by the step grooves 212, 222. When the engagement pins 215, 225 reach the uppermost step portions 213, 223, the magazine holder 216 is located at the uppermost position.

When the engagement pins 215, 225 further advance, the engagement shaft 261 fitted in the elongated hole 255 of the rotation plate 250 moves to the slide plate 220.
By the taper portion 227 of the protruding piece 226, the engaging portion 201 is rotated counterclockwise by being pushed in the counterclockwise direction. As a result, the engaged state of the magazine 100 is released.

When the engaged state is released, the rotating member 240 rotates counterclockwise by the elastic force of the spring 242. At this time, the rotating member 240
Performs a constant rotational movement by the load of the damper 247 that meshes with the gear portion 246. Then, the magazine 100 is attached to the magazine holder by the magazine engaging portion 256 of the rotating member 240.
It is pushed out from the accommodation space 202 of 216.

In this way, when a specific CD storage tray 101 is selected from the magazine 100 accommodated in the magazine holder 216 and sent out to the turntable 501 side, the magazine holder 216 has the engagement pins 215 and 225 provided on the side surface of the side plate of the support frame 700. 70
It moves up and down with respect to the support frame 700 by moving inside the staircase grooves 212, 222 while the movement in the front-back direction is restricted by the elongated hole 718 formed in 3.

Also, on the front side surface of the magazine holder 216, the engaging pin 2
28 are provided. The engagement pin 228 is fitted and inserted into a long hole 721 formed in the side plate 703 of the support frame 700.

At this time, between the tip ends of the engaging pins 215 and 225 penetrating the slide plates 210 and 220 and the side plate 703 and projecting laterally, and the projection 719 formed by cutting and raising a part of the side plate 703, as shown in FIG. As shown in FIG. 2, a spring 720 is stretched. Therefore, the magazine holder 216 is pulled toward the locking projection 719 by the spring 720 and held at a predetermined position in the support frame 700.

The resilience of the spring 720 not only prevents rattling of the magazine holder 216 in the depth direction, but also prevents rattling of the magazine holder 216 in the lateral direction. As a result, the magazine holder 216 does not shake due to vibrations and shocks when the vehicle is running, and the magazine holder 216, the magazine 100, the CD storage tray 101, and the CD are not adversely affected.

As the spring 720, as shown in FIG. 3 and FIG. 4, the tear hole 7 is formed at the end fitted to the engaging pins 215, 225.
It is preferable to use the one to which the collar 723 having the holes 25 is attached. Also, in accordance with this, the engagement pins 215,
As 225, one having enlarged heads 219 and 229 formed at the tip is used.

In this case, the large diameter portion of the tear hole 725 is first set to the engaging pins 215, 225.
The enlarged heads 219,229 of the
Are transferred to the small diameter portion of the tear hole 725. As a result, the enlarged heads 219, 229 are restrained by the small diameter portion of the tear hole 725, and the engagement pins 215,
Color 723 will no longer fall out of 225. Therefore, the spring 720 can be easily attached to the engagement pins 215 and 225 without requiring an attachment such as an E ring.

[Effects of the Invention] As described above, in the present invention, the engaging pin provided on the side surface of the magazine holder penetrates the slide plate and the side plate of the supporting frame in the lateral direction to project the engaging pin and the supporting frame. A spring is stretched between it and a locking projection provided on the side plate to apply a force in the front-rear direction to the magazine holder. As a result, even if the CD player is subjected to vibrations or shocks during vehicle traveling, rattling in the front-rear direction and the left-right direction of the magazine holder is eliminated, and the magazine loading mechanism, the magazine, the CD, etc. are protected.
