Abstract: An optical device and an image pickup device are provided to accurately prevent hand trembling when the optical device is used in the trembling compensation of a camera of the image pickup device, be miniaturized, and save power consumption. A first optical element(32A) includes a first deflection layer(58) and a first and a second transparent electrodes(50,52). The first deflection layer is formed as material whose refractive index is changed according to the amplitude of a supplied voltage. The first and the second transparent electrodes insert both faces of a thickness direction of the first deflection layer. A first optical element(32A) deflects a beam transmitted in the thickness direction of the first deflection layer. A second optical element(32B) includes the second deflection layer and a third and a fourth transparent electrodes(54,56). The second deflection layer is formed as material whose refractive index is changed according to the amplitude of the supplied voltage. The third and the fourth transparent electrodes(54,56) insert both faces of a thickness direction of the second deflection layer. The second optical element deflects a beam transmitted in the thickness direction of the second deflection layer. A first and a second optical elements(32A,32B) are overlapped in the thickness directions of a first and a second deflection layers(58,60). A first and a second transparent electrodes(50,52) supply the first voltage whose amplitude is gradually or continuously changed along the first direction orthogonal to the thickness to the first deflection layer. The third and the fourth transparent electrodes supply the second voltage whose amplitude is gradually or continuously changed along the first direction to the second deflection layer.

Abstract: A lens barrel includes an image-capturing optical system including a movable lens and its drive mechanism including a male screw member extending along the optical axis direction and being rotated by a motor, a female screw member moving along the male screw member with its revolution. The male screw member includes a male screw, and a shaft having an outside diameter equal or less than an inside diameter of a female screw, the shaft extending from an end of the male screw, the end being at an opposite direction to a direction in which the engagement section is in abutment with the end of the female screw member. The female screw member is disposed such that the female screw member can move along the male screw and can move from the male screw to a spot on the shaft in abutment with the male screw.

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: An image stabilization mechanism (1) moves a movable lens or an imager in first and second directions perpendicular to each other and perpendicular to a light axis of the lens or an incident light axis of the imager. The mechanism (1) includes a support member (20) for supporting the movable lens or imager, a base member (10), a guide shaft (30) secured to the base member (10) and extending in the first direction, where the guide shaft (30) is disposed in an elongate hole (21a) formed in the support member (20) in a slidable manner in the first and second directions, an anti-rolling member (40) fitted into the guide shaft (30) in a slidable manner in its axis direction and engaged with the support member (20) in a slidable manner in the second direction so as to prevent rolling of the support member (20) about the light axis, and two drivers for moving the support member (20) independently in the first and second directions.

Abstract: A collapsible lens mount optical unit comprises a fixed lens mount, a lens mount movable along the optical axis with respect to the fixed lens mount, an infrared ray intercepting filter interposed between the fixed lens mount and the lens mount. The collapsible lens mount optical unit further comprises a move-aside mechanism. When the lens mount is retracted and made to approach the infrared ray intercepting filter, the move-aside mechanism moves aside the infrared intercepting filter out of the optical axis in a direction perpendicular to the optical axis. The lens can be accommodated in a position on the optical axis after the infrared intercepting filter is moved.

Abstract: The invention provides a lens holding device comprising a 3-group frame (7) serving as a holding member for holding a lens, a guide shaft (14) serving as a support when the 3-group frame (7) moves along the optical axis of the lens, a rear lens-barrel (8) serving as a fixed reference for suspending the guide shaft (14), a first bearing member (91) formed integral with the rear lens-barrel (8) for supporting that end of the guide shaft (14) which is on the side far from the rear lens-barrel (8), and a guide shaft presser (9) serving as a second bearing member for supporting that end of the guide shaft (14) which is on the side near to the rear lens-barrel (8) with the first bearing member (91) supporting that end of the guide shaft (14) which is on the side far from the base block of the guide shaft (14). Further, the invention also provides a lens-barrel using this lens holding device, and an imaging device.
