Publication number: 20060153555Abstract: The present invention relates to a collapsible type optical unit capable of moving its optical system between a working position and a retracted position as well as an image-pickup apparatus including the optical unit. Particularly, the present invention relates to the optical unit and the image-pickup apparatus capable of acquiring lens-position information by detecting a position of a lens barrel supported to be movable with respect to a fixed barrel. The optical unit according to the present invention is a collapsible type optical unit including: a second group lens frame movable along the direction of its optical axis with respect to a fixed ring and a rear barrel, and a solid-state image-pickup device provided behind the second group lens frame, in which on the movable second group lens frame, a position-detecting means for detecting a position of the second group lens frame is provided.Type: ApplicationFiled: October 24, 2003Publication date: July 13, 2006Inventors: Satoshi Imai, Nobuaki Aoki, Tatsuo Makii, Hideki Yamaoka
