Abstract

PURPOSE:To obtain a positioning device as durable against an external shock by providing a stopper against the rotational direction of a carriage around a guide shaft into a position with such an extent that a rack and a pinion in mesh are not dismeshed with each other toward the guide shaft of the carriage. CONSTITUTION:The stopper 22 is provided in the extent, in which the rack 16 and the pinion 12 are not unmeshable, against the carriage 15 including the rack 16 in their rotational direction. When a shock is given to the head positioning device from the exterior, the carriage 15 and the rack 16 are to be rotated around the guide shaft 19, and then the rack 16 and the pinion 12 in mesh are to be dismeshed, but the carriage 15 is regulated in its movement by the stopper 22 before dismeshing them. When the external shock is gone, the rack 16 and the pinion 12 can be restored to their original meshing condition by a pre-load giving the rack 16 and the pinion 12. By this method, a flexible disk driving device that is durable against an impact force can be obtained.
