Abstract

PURPOSE:To eliminate erroneous counting and to realize the accurate access movement of an optical head, by providing a means to prevent the aberration of an optical scale in a width direction from being generated. CONSTITUTION:In a linear encoder plate 17, an end part on one side is positioned by the positioning pin 22 of a strut 15, and is fixed with a screw, and the 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 with the screw. And as the aberration preventing means in the width direction of the linear encoder plate 17, for example, a pin 18 with a groove is provided. The pin 18 with the groove is fixed in a device, and prevents the aberration of the linear encoder plate 17 in the width direction from being generated. In such a way, the erroneous counting can be eliminated by receiving a beam of light from the light emitting part of the linear sensor accurately by a light receiving part, and reliability can be improved.
