Claims

[Claims for Utility Model Registration] (1) A shutter member movable along one side of the cassette housing for opening and closing an opening window that exposes the recording/reproducing surface of a disk body housed in the cassette housing. In a disk drive device in which a provided disk cassette is removably loaded, a linear elastic member is provided extending in a predetermined direction from a support point provided on a cassette holder side that accommodates the cassette toward a rear part of the cassette holder. and bending the distal free end side toward the storage space side, and configuring the bent portion to be engageable with the shutter member side or an engaging portion formed between the shutter member and the cassette case, A disk drive device characterized in that a rotation space is formed on the side of the bending portion in the shutter member movement direction in which the bending portion engaged with the engaging portion can move in accordance with the cassette loading operation. (2) The scope of the utility model registration claim, characterized in that the elastic member extends parallel to the cassette storage surface and at a predetermined angle of inclination toward the shutter member return direction with respect to the cassette loading direction. The disk drive device according to item 1. (3) With the bent portion engaged with the engaging portion, by further pushing the disk cassette into the cassette storage space, the opening window portion is opened by the biasing force of the linear elastic member. The utility model according to claim 1 or 2, wherein while the shutter member moves in the direction, the bent portion is inserted into a notch formed on the cassette housing side at the mounting completion position. disk drive device.
