[0005]

By the way, the conventional CD
In the autochanger body 44, when playing the CD 21a, the CD 21a is moved from the magazine 20 to the playing portion 43 side.
It was necessary to completely remove a, but with the advancement of technology in recent years, it has become possible to play the CD 21b by removing about half of the CD 21b from the magazine 20 to the playing section 33 side. As a result, the playing unit 33 becomes smaller than the playing unit 43, and the housing 3
The length L ₁ of ₁ is shorter than the length L ₂ of the housing 41, so that the CD autochanger main body 34 can be made smaller than the CD autochanger main body 44.

However, in the above door structure 49,
The length L ₃ of the opening 35 does not change and therefore the door 36
Since the length L ₃ of the CD does not change, when the door 36 is opened, the door 36 cannot be completely accommodated in the door accommodating portion 38 and protrudes from the CD automatic changer main body 34. As a result,
When the CD autochanger body 34 is mounted in a dashboard (not shown) or the like, the protruding portion 36a comes into contact with another device and the door 36 does not open completely, or the opening space of the protruding portion 36a is secured in advance. Need to be kept. Therefore, even if the CD autochanger main body 34 is downsized, it is difficult to actually downsize the entire device due to the restriction of the door structure 49, and it is difficult to mount it on the dashboard.

The present invention has been made in view of the above problems, and even when the shape of the door accommodating portion is smaller than the shape of the opening, the door when opened can be reliably placed in the door accommodating portion of the housing. It is an object of the present invention to provide a door structure that can be accommodated and that can realize downsizing of the entire device.

On the other hand, when the second door is rotated and closed, and then the first door is slid to a position in the opening which is not closed by the second door, the first door and the first door are closed. With the two doors, the entire opening can be closed completely. Further, even if the shape of the door accommodating portion is smaller than the shape of the opening, the first door can be reliably accommodated in the door accommodating portion, and the first door when opened is a device. Since it is prevented from protruding to the lateral side of the device, it is possible to reduce the size of the entire device.

Further, according to the door structure (2) of the present invention, since the second door is constantly urged in the opening direction by the elastic body, substantially the same operation as in the door structure (1) can be obtained. When the first door passes through the front of the second door and is accommodated in the door accommodating portion, the regulation force of the first door does not act. Then, the second door is automatically opened. On the other hand, when the first door is started to be closed, the front end of the first door pushes the front surface of the second door to generate a rotational force, so that the second door can be automatically closed. Become. Therefore, the opening / closing operation of the first door automatically opens / closes the second door at the same time, which facilitates the opening / closing operation.
