摘要： 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. According to the present invention, projection and the like on the exterior portion can be eliminated to be small in size and an increase of the number of parts and the number of processes can be restricted to the minimum.

摘要： The present invention provides a lens holder comprising a third group frame that serves as a holding member which holds lenses, a guide shaft that supports the third group frame when the third group frame is moved along the optical axis of the lenses, a rear barrel part perpendicularly to which the guide shaft is locked, a first bearing member that is molded as an integral part of the rear barrel part in order to bear the end of the guide shaft distal to the rear barrel part, and a guide shaft presser that when the first bearing member bears the end of the guide shaft distal to the base, bears the end of the guide shaft proximal to the rear barrel part. Moreover, the present invention provides a lens barrel and an imaging apparatus that employ the lens holder. Consequently, the structure of a bearing that bears a shaft which supports the lens holding member when the lens holding member is moved along the optical axis of the lenses is downsized. Moreover, the bearing bears the shaft highly precisely.

摘要： This prevents biting and miniaturizes an entire mechanism. There is provided a lens driver including: a driver having a frame that holds a lens and a bearing for receiving a guiding axis to move the lens in an optical axis direction, a lead screw in which a screw to which a nut is screwed is formed, and a stepping motor for rotating the lead screw; an arm extended from the frame, in such a way a tip being next to the nut, and moving the frame by movement of the nut; a spring for pushing an arm tip towards the nut; and an idle rotation section placed on only side where the arm is placed for the nut at a lead screw end of the driver, and has an axis diameter disabling the nut to be screwed. Also there is provided an image capture apparatus having the lens driver.
