ーデスクのチヤツク装置。 A drive pin that protrudes from the top surface of the turntable through a through hole provided in the turntable on which the floppy disk is placed and engages with a drive hole of the floppy disk is inserted between the center of the through hole and the It is planted on one side of a right-angled arm that is rotatably supported by a fulcrum pin provided on the underside of the turntable at a position away from the line connecting the centers of the turntable drive spindles, and rotates around the fulcrum pin. The turning locus of the drive pin intersects the line connecting the center of the spindle and the center of the through hole at a point that has turned very slightly, and there is a gap between the tip of the other side of the right-angled arm and the bottom surface of the turntable. The floppy piece is characterized in that the long side of the arm is held at the center of the spindle by the tension of a stretched coil spring, and the drive pin installed on the short side of the arm is moved toward the outer circumference of the turntable. Desk check device.
