Patent number: 6272288Abstract: A vibration correction system for a camera using a correcting lens driven by a reduction gear train attached to a motor. Image deflection, originating from vibration and the like of the camera, is prevented by shifting the correcting lens. A movement detector, to detect the amount of movement of the correcting lens, is arranged near the drive shaft of the motor or near the first couple of gears of the reduction gear train. After the correcting lens has been driven, the connecting lens is reset to a predetermined standard position, based on the output of the movement detector. By placing the movement detector on or near the drive shaft, a high resolving power is obtained. Accordingly, the correcting lens can be shifted with fine precise movements, and accurate correction of image deflection becomes possible.Type: GrantFiled: February 17, 1999Date of Patent: August 7, 2001Assignee: Nikon CorporationInventors: Yoshihiro Takeuchi, Hidenori Miyamoto, Isao Soshi, Minoru Kato, Junichi Omi

Patent number: 5999747Abstract: An image deflection preventing device for a camera, such as a still camera which is used to drive a deflection preventing optical system in accordance with readings from angular velocity sensors and other circuitry. Moreover, an exposure mode selection device is included to select strobe photography according to the focusing distance from a distance measuring unit maintained in the camera to a subject to be photographed. The selection device can select strobe photography when the focusing distance is closer than a predetermined distance or when photographic magnification from a focal length detection unit to a subject to be photographed is greater than a predetermined value. The selection of strobe photography is done using results from a photometric unit in conjunction with the determination of a brightness level. In particular, if a given brightness level is equal to or greater than a predetermined value, strobe photography is selected, otherwise, exterior light photography is selected.Type: GrantFiled: March 3, 1997Date of Patent: December 7, 1999Assignee: Nikon CorporationInventors: Yoshio Imura, Hidenori Miyamoto, Isao Soshi, Minoru Kato, Junichi Omi

Patent number: 5930042Abstract: An optical lens barrel having a lens group which serves as a vibration compensation lens group and a focusing lens group. The lens group is held by a holder movably secured to a plate. The lens group is movable within the plate on a plane perpendicular to an optical axis of the lens group via a pair of DC motors and associated gear trains. The DC motors and associated gear trains are mounted on the plate. The plate is slidably movable parallel to the optical axis of the lens group by a stepping motor via a series of concentric drive rings disposed around the plate. The drive rings also actuate an aperture mechanism which serves as a shutter. This reduces both the number of lenses and components needed to provide vibration compensation and autofocusing functions.Type: GrantFiled: December 9, 1994Date of Patent: July 27, 1999Assignee: Nikon CorporationInventors: Hidenori Miyamoto, Isao Soshi, Minoru Kato, Junichi Omi

Patent number: 5905918Abstract: A camera displacement mechanism control device can maintain the time required to effect removal of backlash within a set time. Zooming-down is started by the zoom-down switch being turned ON, and the lens barrel is driven as far as the wide-angle terminus if the zoom-down switch is not turned OFF during zooming-down. Alternatively, if the zoom down switch is turned OFF during zooming-down, the lens barrel is driven to the next halt position after the position where the zoom-down switch was turned OFF. In either case, the lens barrel is caused to overshoot the target halt position in the direction of scrolling-in for a time interval long enough to effect removal of backlash, and is subsequently driven in the direction of scrolling-out and halted at the described target halt position.Type: GrantFiled: January 8, 1997Date of Patent: May 18, 1999Assignee: Nikon CorporationInventors: Toshiyuki Nakamura, Tatsuo Amanuma, Hidenori Miyamoto, Minoru Kato

Patent number: 5754896Abstract: A lens device having a base unit, a lens unit and an intermediate member. The base unit includes a drive ring which is rotatable around an optical axis of the lens device and has a coupling portion which protrudes into the housing space. The lens unit is inserted into a housing space of the base unit. Moreover, the lens unit is rotatable around the optical axis of the lens device and rotatably coupled to the base unit so that the rotation of the lens unit around the optical axis of the lens device causes the lens unit to move along the optical axis. The intermediate member is connected to the lens unit and has a groove. The coupling portion of the drive ring is engaged in the groove so that the rotation of the drive ring causes the coupling portion to interact with the groove to move the intermediate member. The movement of the intermediate member causes the lens unit to rotate around, and thereby move along, the optical axis in accordance with the rotation of the drive ring.Type: GrantFiled: January 29, 1997Date of Patent: May 19, 1998Assignee: Nikon CorporationInventors: Hitoshi Aoki, Minoru Kato

Patent number: 5715482Abstract: A miniaturized collapsible zoom camera changes viewfinder magnification in accordance with a change in the photographic magnification. The camera is equipped with a collapsible cam tube to cause a first lens group, which rotates around the optical axis, to move from a collapsed position to a position just before a minimum magnification position. Likewise, a zoom cam tube causes the first lens group, which rotates around the optical axis, to move from the minimum magnification position to a maximum magnification position. Sector gears are formed on the outer circumference of the collapsible cam tube and the zoom cam tube. Furthermore, the camera is equipped with a cam tube drive gear which cooperates with the sector gears. A drive motor causes the drive gear to rotate. Another gear cooperates only with the sector gear of the zoom cam tube while a variable power and movement mechanism causes variable power operation in the viewfinder.Type: GrantFiled: February 7, 1997Date of Patent: February 3, 1998Assignee: Nikon CorporationInventors: Hiroshi Wakabayashi, Hidenori Miyamoto, Minoru Kato, Isao Soshi, Junichi Omi

Patent number: 5708266Abstract: An apparatus to detect the amount and direction of rotary motion for use in a vibration compensation system in an optical camera. An indicator disk is provided around the output shaft of a motor which actuates a compensation lens to compensate for vibrations to the camera. The periphery of the indicator disk is provided with a series of holes. A pair of photodetectors, are arranged on the periphery of the disk so as to detect the holes passing thereunder. The two photodetectors are separated by a distance equal to 3/4 of the distance between two holes. By comparing the pattern of signals emitted by the photodetectors the direction of rotation of the indicator disk can be determined. Further, the pulses in the output of either photodetector can be counted to determine the amount of movement. The actual direction and amount of movement as calculated is provided to a vibration compensation circuit as feedback for use in controlling the compensation lens.Type: GrantFiled: May 28, 1996Date of Patent: January 13, 1998Assignee: Nikon CorporationInventors: Isao Soshi, Hidenori Miyamoto, Minoru Kato, Junichi Omi, Tatsuo Amanuma, Toshiyuki Nakamura

Patent number: 5701245Abstract: A suspension control system of the present invention varies a damping force according to a velocity ratio of a mass-body velocity to a relative velocity, while ensuring both a comfortable drive and stable cruising. In the suspension control system, a CPU calculates a mass-body velocity Zd and a relative velocity Yd based on detection signals from sensors and determines a velocity ratio Zd/Yd (steps S110 and S120). A small skyhook damping coefficient is set for a small vehicle speed V to reduce a damping force according to the velocity ratio Zd/Yd (step S130). In the process of varying the damping force, a stepping motor used for the variation in damping force is driven at a low driving frequency for a small vehicle speed V (step S180).Type: GrantFiled: October 6, 1995Date of Patent: December 23, 1997Assignee: Toyota Jidosha Jabushiki KaishaInventors: Kazuo Ogawa, Takaaki Enomoto, Masato Kawai, Minoru Kato, Kunihito Sato
