01 presses down one end of the CD presser lever 403 with this pressing force. Therefore, the CD presser lever 403 is
It rotates counterclockwise around a fulcrum 645.

In synchronization with the operation of the push lever 301, the slide lever 6
20, the engagement pin 656 moves while being guided by the guide groove 414 of the guide plate 415, and the clamp release lever 410 rotates clockwise.

As a result, the clamp arm 690 rotates due to the biasing force of the spring, and the clamper 891 approaches the turntable 501. At this time, the clamper 691 lifts the CD toward the turntable 501 while contacting the center of the CD. As a result, the central portion of the CD is held between the clamper 69 and the turntable 501.

In synchronization with the operation of the clamper 691, the tip of the rotating piece 420 gradually rotates upward, lifting one end of the movable shaft 422 against the biasing force of the spring. Then, the horseshoe-shaped presser ring 423 rises while maintaining a constant slight distance from the CD.

When the clamping operation is completed, the motor 502 is driven,
The turntable 501 rotates to rotate the CD.

At this time, stepping motor 504 is also driven at the same time. The stepping motor 504 is powered by a small pulley 50.
3. Rotating shaft 5 via belt 506 and large pulley 505
This will be communicated to 07. Then, when the rotating shaft 507 rotates,
The pickup 510 engages with the threaded portion 508,
It gradually moves to the right while being guided by the guide rail 511. After the pickup head of the pickup 510 reads the information in the TOC area of the CD, it moves to a predetermined area, and the information recorded in that area is read out.

In this way, information such as music recorded on the CD is reproduced.

To finish reading the information, operate the end button on the control device built into the dash photo. In this operation, first, the drive of the motor 502 is stopped, and then the drive motor 601 is driven to rotate the rotary cam 810 counterclockwise. This causes each part to return to its predetermined position by operating in the reverse order. and,
After the CD is released from the clamped state, it is transferred to the CD storage tray 101 and stored at a predetermined position within the magazine 100.

Further, when the eject button of the control device is pressed, after the CD storage tray lot is stored in the magazine 100, the drive motor 6 (18) is driven in the opposite direction to that at the time of loading. Rotation is gear group 6
07 to the gear section 606, and the slide plate 21
Move 0 to the back. The other slide plate 220 is connected to the slide plate 210 via a seesaw lever, so it moves in the opposite direction, that is, forward.

By moving the slide plates 210 and 220, the engagement pin 2
15.225 is pushed up by the step grooves 212 and 222. The engagement pin 215.225 is the uppermost step 213.22
3, the magazine holder 216 is located at the uppermost position.

When the engagement pins 215 and 225 move further, the engagement shaft 261 fitted into the elongated hole 255 of the rotation plate 250 is pushed counterclockwise by the tapered portion 227 of the protruding piece 226 of the slide plate 220. , the engaging portion 201 rotates counterclockwise. As a result, the magazine 100 is disengaged.

When the engaged state is released, the rotating member 240
It rotates counterclockwise due to the repulsive force of 2. At this time, the rotating member 240 performs a constant rotational movement due to the load of the damper 247 that meshes with the gear portion 246.

Then, the magazine 100 is pushed out of the accommodation space 202 of the magazine holder 21B by the magazine engaging portion 256 of the rotating member 240.

Here, in this embodiment, as described above, the magazine 10
A pair of left and right regulating ribs 219, 219 are formed on the upper inner surface of the magazine holder 21B, which faces the upper surface of the push-back action end when loading the magazine holder 21B, that is, the front end.

Therefore, when the magazine 100 is loaded into the housing space 202 of the magazine holder 216 against the push-back force caused by the engagement of the rotating member 240 with the magazine engaging portion 256, the third
As shown in the figure, the top surface of the magazine 100 on the push-back action end side comes into contact with the regulating ribs 219, 219 to prevent floating, and the bottom surface of the magazine 100 on the opposite side from the push-back action end contacts the guide rail 203 and the guide rib 204. The posture that comes in contact with makes a roar. At this time, the regulating rib 219° guide rail 203. The guide ribs 204 are curved.

Therefore, regardless of the push-back action point of the magazine 110, that is, the engagement position with the magazine engaging portion 256, or even if the push-back force of the magazine engaging portion 256 is large, the magazine 100 cannot be loaded in the vertical direction. Posture is properly regulated.

In this way, since the push-back end of the magazine 100 is prevented from lifting up, the multi-type CD player can be placed not only horizontally, but also vertically.
The loading posture of the magazine 100 in the vertical direction can be correctly regulated.

In the above embodiment, the pair of left and right regulating ribs 219, 219 provided on the magazine holder 21B may be provided in the center of the magazine holder 216 in the width direction. It may also be composed of protrusions.

Further, the present invention is not limited to the magazine holder of a multi-type CD player into which a CD storage magazine is inserted as in the above embodiment, but can also be applied to a magazine holder that uses other magazines.

[Effects of the Invention] As explained above, according to the present invention, when a magazine is loaded into the magazine holder, the upper surface of the push-back end side of the magazine comes into contact with the regulating protrusion, preventing the magazine from floating up. The lower surface of the opposite end comes into contact with the rib to determine its posture.

Therefore, the loading posture of the magazine in the vertical direction can be correctly regulated regardless of the position of the push-back point of the magazine.
