发明名称 Position detecting apparatus for use with image blur correcting device having movable member
摘要 A position detecting apparatus applied to an image blur correction device having a movable member has a light emitting device, a reflecting member for reflecting light from the light emitting device, which has portions with different reflectivities and in where a position upon which the light from the light emitting device impinges changes according to movement of the movable member, and a light receiving device for receiving light reflected by the reflecting member and for outputting a signal representing a position of the position-detected object in accordance with the light received, thereby realizing the position detecting apparatus in the simplified and cost-reduced configuration. Further, the above position detecting apparatus is used for position detection of a movable member for preventing an image blur in an image blur correction apparatus or a movable optical member in an optical apparatus, thereby simplifying the configuration and decreasing the cost for the image blur correction apparatus or the optical apparatus.
