PURPOSE:To automatically clamp and set a magnetic disk only by inserting the magnetic disk, by detecting the insertion of the magnetic disk to a normal position through a sensor, and then operating a cone loading driving source on the basis of the detection signal of the sensor. CONSTITUTION:An one end of a shaft 43 coupled with a cone loading solenoid 41 through a wire 48, a roller 44 for displaying a cone 30 in a shaft direction is provided facing a rigid plate 38, and at the other end, a shutter 50 which rotates to open or close an insertion opening is fixed. Once the 1st sensor 52 detects the insertion of a floppy disk into the insertion opening, the cone loading solenoid 41 is driven by its detection signal, and the rigid plate 38 is displaced to move the cone 30 toward a driving hub. Thus, the magnetic disk is clamped and set automatically only by insertion. |
