Claims

[Claims for Utility Model Registration] A floppy disk device having a plurality of openings for taking in and taking out floppy disks, each of which has a door, comprising: an opening/closing rod vertically fixed to each of the doors; and the floppy disk. A fixed shaft provided vertically in the device corresponding to the door; and a fixed shaft fitted to the fixed shaft so as to be horizontally rotatable about the axis of the fixed shaft and movable up and down. A horizontal arm attached at right angles to the fixed shaft, one side of the arm is a convex surface that starts from the tip of the arm, has a center of curvature on the fixed shaft side, and extends away from the arm. forming a curved portion extending as shown, and having a wedge-shaped notch cut in a direction from the tip of the curved portion to the tip of the arm;
a horizontal arm, the other end of the notch being connected to a rod-shaped protrusion protruding from the arm, and having a groove in the lower surface of the arm into which the top of the upper end of the opening/closing rod can fit and slide; a spring provided above the fixed shaft to press downward and provide resistance to horizontal rotation of the arm; a stopper device to lock the horizontal arm; and a stopper device to horizontally press the horizontal arm. A floppy disk device comprising: a swing device for opening the door; and a control device including a push button switch for operating the stopper device and the swing device.
