Claims

[Scope of utility model registration request]

A moving base □ on which a magnetic head is mounted and a housing, a lead screw having a groove spirally carved around the periphery in which the ball of the housing engages, and passing through the moving base, and both ends of this lead screw. a plate spring inserted into one end of the lead screw, a thrust bearing provided on the feed base that presses the other end of the lead screw, and a stopper that restricts the amount of movement of the housing. A head feeding mechanism for a floppy disk device, comprising: a stepper motor provided on the feeding base; and a flexible coupling connecting the lead screw and the shaft of the stepper motor.
