This ejecting operation hole 181 is formed in a position covered with the inside of a door body 112 for closing a cartridge inserting/detaching port 110, in such a way as to forcibly move the cartridge holder from a loading position to an inserting/detaching position at emergency time when the movement of the cartridge holder by a loading driving mechanism is disabled.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording and / or reproducing apparatus for recording and / or reproducing information signals on a recording medium cartridge such as a magnetic disk cartridge.

[0002]

2. Description of the Related Art Conventionally, there is a disk cartridge in which a magnetic disk is rotatably housed in a cartridge body. An example of such a removable disk cartridge is a magnetic disk having a signal recording layer formed on a flexible disk substrate and having a diameter of 3.5 inches, that is, a so-called flexible disk as an information recording medium. It has been known.

A disk drive device 300 in which a disk cartridge of this type is mounted to record and reproduce information signals on a magnetic disk has a front panel having a cartridge insertion / removal opening through which a disk cartridge is inserted into / removed from the main body of the device. The front panel includes an opening / closing door which is provided to be openable and closable at a cartridge insertion / removal opening, a cartridge holder movably disposed between a cartridge mounting position and a cartridge mounting position, and a lifting operation plate for raising and lowering the cartridge holder. And a loading mechanism.

In the conventional disk drive device, a cartridge holder is provided on the front panel to forcibly move the cartridge holder from the cartridge device position to the cartridge insertion / removal position in an emergency when the movement of the cartridge holder is disabled. An ejection operation hole through which a push-in operation pin for pushing-in operation is inserted is formed.

In a disk drive device, a pushing operation pin is inserted into an ejecting operation hole, and the pushing operation pin pushes an abutting piece formed on a cartridge holder, whereby the cartridge holder is moved to a cartridge insertion / removal position. It is moved and the disk cartridge is ejected.

[0006]

However, in the above-mentioned conventional disk drive device, the eject operation hole is provided in the front panel, so that it is always exposed outside the device body. For this reason, in the conventional disk drive device, when external dust enters through the eject operation hole and adheres to the signal recording surface of the magnetic disk in the device main body or the recording / reproducing mechanism, the information signal recording / reproducing on the magnetic disk is performed. There is a problem that it is not possible to perform accurately.

Further, as described above, since the ejecting operation hole is always exposed to the outside, the cartridge holder is erroneously operated due to the operation member being erroneously inserted with the pushing operation pin or the like. There was a fear.

Accordingly, an object of the present invention is to provide a recording and / or reproducing apparatus capable of reliably preventing dust from entering the apparatus main body from a discharge operation hole.

[0009]

In order to achieve the above-mentioned object, a recording and / or reproducing apparatus according to the present invention is formed at a position covered by an inside of a door that closes an insertion / removal opening and is provided with a driving means. In order to forcibly move the cartridge holder from the mounting position to the insertion / removal position in an emergency where the movement of the cartridge holder due to is impossible, a discharge operation hole through which a pushing operation member for pushing the cartridge holder is inserted is provided.

In the recording and / or reproducing apparatus configured as described above, since the discharge operation hole is covered by the inside of the door that opens and closes the insertion / removal opening, external dust is discharged by the door. Is regulated.
