Abstract: An image blur correcting unit allows the optical axis of a lens system to coincide with the center of an imager, thus correcting an image blur. The unit includes a stationary member and a holder member. The holder member holds either one of the elements of the lens system or the imager and moves relative to the stationary member in a first direction and a second direction, the first and second directions being orthogonal to each other in a plane orthogonal to the optical axis. The unit further includes a first guide section and a second guide section for guiding the holder member in the first and second directions during movement, and a driving section moving the holder member in the first and second directions. The one of the elements of the lens system or the imager is disposed outside an area surrounded by the first and second guide sections.

Abstract: A lens holder includes 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.

Abstract: 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.

Abstract: 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.
