Claims

[Scope of Claim for Utility Model Registration] (1) A concave shape with upper and lower guide grooves formed at opposing positions on the left and right side walls, and one guide post parallel to the direction of insertion of the spindle motor, step motor, IC board, and cartridge. a frame for fixing the frame, a slide plate formed into a concave shape that can be slid on the frame, and a slide plate having guide grooves having slopes and flat surfaces at opposing positions on the left and right side walls thereof, and a roller that engages with each of the guide grooves. movement of a slide plate which is rotatably supported by the guide post and slides in the direction of cartridge insertion; 1. A magnetic head support device for an FDD, in which a carriage is rotated by a push-up member that receives an FDD, and the push-up member is an elastic plate member that is fixed to the carrier at one end and presses the carriage at the other end. (2) Claim 1, wherein the push-up member has elasticity, has one end fixed to the slide plate, and has a U-shaped push-up part formed at the other end to receive the protrusion of the frame, and presses the carriage with the tip of the push-up part. A magnetic head support device for the FDD described above. (3) The push-up member is rotatably supported by a shaft fixed to the frame, and the locking part that locks into the window of the slide plate and rotates the push-up member itself is bent and formed, and the push-up part that presses the carriage is separate. 2. The magnetic head support device for an FDD according to claim 1, wherein the magnetic head support device is formed by bending.
