摘要： A lens barrel standard position detection device, attached to a lens barrel equipped with a fixed tube having a first member and a movable tube rotationally moving back and forth along an optical axis of the lens barrel and having a second member engaging the first member of the fixed tube, to detect when the movable tube reaches a predetermined standard position. The lens barrel standard position detection device includes an actuating element movable between a first position and a second position, the actuating element moving to the second position when a working plane portion of the second member moves into contact with the actuating element corresponding to the movable tube reaching the predetermined standard position along the optical axis, an urging member which maintains the actuating element in the first position in a normal state due to an urging force of the urging member, and a detection unit which detects when the actuating element moves to the second position which opposes the urging force of the urging member, thereby detecting the movable tube reaching the predetermined standard position.

摘要： A camera having a lens barrier unit that opens without encountering obstructions in response to the operation of an operating member and without increasing the size of the lens barrel of the camera. The lens barrier unit covers the front surface of a photographic lens in a closed position, and moves clear of the front surface of the photographic lens in an open position. A sliding member, which is a separate member from the operating member, mechanically drives the lens barrier unit to an open position in response to the movement of an operating member by means of the operation for photographic preparation (e.g., when the camera is switched ON), and drives the lens barrier unit to a closed position, by coupling to the movement of the photographic lens unit while moving from the extended position to the retracted position (e.g., when the camera is switched OFF). The camera may include a finder optical system for visually recognizing an image of an object, with the sliding member disposed in the vicinity of a film aperture. The slide member is disposed in a face-to-face position to the finder optical system with the film aperture being interposed therebetween.

摘要： In a camera, there is a requirement for ensuring the timing of opening and closing a film cartridge light cutoff door when a cartridge chamber lid is opened and closed, and moreover for lightening the operational force for opening and closing the cartridge chamber lid. In view of these requirements, the camera according to the present invention includes a cartridge chamber into which a film cartridge which comprises a light cutoff door is loaded, a cartridge chamber lid which is selectively opened and closed so as respectively to communicate the cartridge chamber to the exterior or to isolate the cartridge chamber from external light, and a door opening and closing mechanism which exerts opening driving force upon the light cutoff door so as to open it, after the cartridge chamber has been isolated from external light by closing operation of the cartridge chamber lid. Preferably, the door opening and closing mechanism comprises an energy storage mechanism which stores energy from the cartridge chamber closing operation in order to open the light shielding door of the cartridge. The opening of the light cutoff door is started only after the cartridge chamber has been isolated from external light by closing operation of the cartridge chamber lid.

摘要： A high magnification zoom lens barrel including a drive ring having a short length in the optical axis direction to permit a compact camera configuration. The zoom lens barrel includes a first lens group support member to support a first lens group, and a second lens group support member to support a second lens group. The drive ring advances and withdraws the first lens group support member in the optical axis direction as the drive ring itself advances or withdraws in the optical axis direction as it rotates. The drive ring drives the first lens group support member with helicoids. A drive cam member is driven by the drive ring to rotate so that as the drive cam member rotates, it advances and withdraws the second lens group support member relative to the first lens group support member. A second drive ring is inserted into the drive cam member and rotates relative to the drive ring and is able to move in unison with the drive ring in the optical axis direction.

摘要： To avoid making a device body larger through positioning of a rotation shaft of a cartridge cover, a device having a device body containing a cartridge chamber into which a film cartridge can be inserted and removed in a axial direction, a cartridge cover provided on the device body which opens and closes the cartridge chamber by rotating about a predetermined axis of rotation, and a device-composing component positioned to the side of the cartridge chamber to extend in a first direction orthogonal to the direction of insertion and removal of the cartridge, the axis of rotation of the cartridge cover extends in a second direction inclined to the first direction from a position near device-composing component. The positioning of the axis of rotation of the cartridge cover in the camera body and not along an edge or corner also improves the camera's aesthetic and ergonomic qualities.

摘要： A lens barrel having first and second lens groups and first and second tubes. The first tube has first and second guide grooves to respectively guide the first and second groups in an optical direction. The second tube has first and second cam grooves to respectively guide the first and second lens groups, in conjunction with the first and second guide grooves, for focusing and zooming operations. A first collapsing use groove extends substantially perpendicular to the optical axis from an end of the second guide groove that is closer to an image surface to maintain the second lens group in a stationary position on the optical axis when the first lens group is collapsed toward the second lens group and when the first lens group is extended into a wide state. A second collapsing use groove extends substantially perpendicular to the optical axis from an end of the second cam groove that is closer to the image surface and overlaps the first collapsing use groove to perform the same functions as the first collapsing use groove. The first cam groove is inclined with respect to the optical axis and the second cam groove includes a wide state focusing portion extending substantially parallel to the first cam groove from an end of the second collapsing use groove portion to guide the second lens group uniformly with a movement of the first lens group for focusing of the first and second lens groups in the wide state. The second cam groove above the wide state focusing portion is a stepped groove having alternating zooming portions and focusing portions, wherein the zooming portions are inclined from the optical axis and the focusing portions are substantially perpendicular to the optical axis.
