フロツピーデイスク装置。[Claims for Utility Model Registration] (1) A motor having a rotor that rotates integrally with a turntable for mounting a disc-shaped recording medium, and a stator that is attached to a device board facing the rotor. ,
A floppy disk comprising an index magnet fixed to the circumferential surface of the rotor along the rotation direction thereof, and a position detection means fixed to the stator and having a detection element for detecting the magnetic flux of the magnet. In the device, the position detection means includes a rotary plate provided with the detection element on a surface facing the circumferential surface of the rotor and rotates on a plane parallel to the axis of the rotor, and the rotary plate and the fixed member. A floppy disk device comprising: an adjusting mechanism disposed between the floppy disk device and the floppy disk device to rotationally adjust the rotary plate and vary the relative position of the detection element and the magnet with respect to the device board. . (2) The adjustment mechanism includes a bracket mounted on the stator, and a rotating member rotatably attached to the bracket, having the rotating plate fixed to one end and a screwdriver locking groove at the other end. A floppy disk device according to claim (1) of the utility model registration claim, characterized in that the floppy disk device comprises:
