DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk device for recording and reproducing information on and from a disk housed in a cartridge. Particularly, even when an erroneous insertion is made, the cartridge is securely held until the erroneous insertion prevention mechanism is reached. To a cartridge holder that can be used.

[0002]

2. Description of the Related Art In a disk device using a cartridge, when the cartridge is inserted into the device, the cartridge is held by holding means called a cartridge holder, and then the cartridge holder is moved by a loading mechanism, and the cartridge holder is moved to the cartridge holder. It is customary to mount the held cartridge at its mounting position and mount the disk on the rotary drive.

If the cartridge is inserted in the wrong direction into the cartridge holder, the cartridge may damage the recording / reproducing optical head or the like, so that the cartridge may not be inserted into the cartridge holder halfway. A prevention mechanism is provided.

Conventionally, the depth dimension (dimension in the normal insertion direction) of the cartridge is made larger than the width dimension (dimension in the direction perpendicular to the normal insertion direction), and the width dimension inside the cartridge holder is reduced to the width dimension of the cartridge. It was set accordingly. In this case, when the cartridge is erroneously inserted with the left side or right side with respect to the normal insertion direction at the top, since the depth dimension of the cartridge is larger than the inner dimension of the cartridge holder, the cartridge is caught by the entrance of the cartridge holder. , So that it could not be inserted.

As such a disk device, for example,
There is one described in JP-A-61-246957. In this example, a stopper is provided at a position corresponding to the notch provided on the leading end side of the cartridge when the cartridge is inserted in the normal insertion direction, and the cartridge is engaged when the notch of the cartridge is engaged with the stopper. The front end face in the insertion direction operates a trigger lever for starting mounting of the cartridge. When the cartridge is erroneously inserted, the notch of the cartridge and the stopper cannot be engaged, and the insertion of the cartridge is restricted by the stopper, so that the trigger lever cannot be operated.

[0006]

However, in the above-mentioned conventional disk drive, no consideration has been given to using a cartridge whose width is longer than the depth of the cartridge. That is, when this conventional technique is applied to a disk device assuming a cartridge having a width dimension larger than the depth dimension of the cartridge, if the left or right side in the normal insertion direction is erroneously inserted at the top, The cartridge may come off from the support portion of the cartridge holder, and the inserted cartridge may damage the recording / reproducing head.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a disk drive assuming a cartridge having a width larger than the depth of the cartridge.
Even if the left or right side is mistakenly inserted at the top with respect to the normal insertion direction, the cartridge of the disk device can reliably guide the cartridge until it reaches the erroneous insertion prevention means without the cartridge coming off the cartridge holder. It is to provide a holder.

[0008]

In order to achieve the above object, according to the present invention, the width of a support portion of a cartridge holder which holds a cartridge having a width dimension w larger than a depth dimension d is defined, and the cartridge having a small dimension is formed. when inserted into the cartridge holder under the heading of depth side, at least in the inlet portion so as to be supported by the supporting portions on both sides are supported <br/> lifting the portion up to the insertion preventing mechanism erroneous from the inlet portion It was to so.

Further, when the cartridge insertion port into housing side is provided, the width of the support portion of the cartridge holder, between the insertion preventing mechanism erroneous from the inlet portion and the inlet portion, defined as supported lifting did.

[0010]
