Abstract
PURPOSE:To realize the accurate access movement of an optical head by eliminating erroneous counting, by providing a means to prevent the deflection of an optical scale in a direction intersecting orthogonally to a plane including the length direction and the width direction of the optical scale. CONSTITUTION:One end of a linear encoder plate 17 is fixed with a screw at a strut 15, and an end part on the other side is bent in a perpendicular direction to save a space by a strut 16 in which circular arc chamfering is applied on its corner part, and the end part is fixed at a member 19 with a screw hole with the screw. And as a deflection preventing means for the linear encoder plate 17, for example, a pressing spring 22 by a thin spring is provided. The pressing spring 22 is fixed at the strut 16 with the screw, and prevents the encoder plate 17 from being deflected by pressing the plate. In such a way, the erroneous counting can be prevented from being generated by receiving a beam of light from the light emitting part of a linear sensor by a photodetecting part, and reliability can be improved.
