| 20100091120 | OPTICAL UNIT WITH SHAKE CORRECTING FUNCTION - An optical unit with shake correcting function may include a movable module having a lens, a fixed body supporting the movable module, a shake detection sensor for detecting shake of the movable module, and at least one pair of magnetic drive mechanism for shake correction which is structured on both sides of the movable module so that the movable module is swung with respect to the fixed body on the basis of detection result of the shake detection sensor to correct the shake of the movable module. The magnetic drive mechanism for shake correction is disposed so that a shake correction magnet is held by the fixed body and a shake correction coil is held by the movable module. Further, a shake correction coil may be disposed in a first region, where magnetic lines of force generated by a shake correction magnet are directed in directions generally going away from a supporting point part and/or a second region where magnetic lines of force generated by the shake correction magnet are directed in directions generally going toward the supporting point part. | 04-15-2010 |
| 20100098394 | OPTICAL UNIT WITH SHAKE CORRECTING FUNCTION AND SHAKE CORRECTION CONTROL METHOD THEREFOR - An optical unit with shake correcting function may include a movable module on which at least an optical element is mounted, a fixed body which supports the movable module, a shake detection sensor which detects a shake of the movable module, a drive mechanism for shake correction for swinging the movable module on the fixed body on the basis of a detection result of the shake detection sensor to correct the shake of the movable module, and a control section which controls the drive mechanism for shake correction on the basis of the detection result of the shake detection sensor. The shake detection sensor is a gyroscope mounted on the movable module and the control section controls the drive mechanism for shake correction so as to cancel the shake detected by the gyroscope. | 04-22-2010 |
| 20110097062 | OPTICAL UNIT WITH SHAKE CORRECTING FUNCTION - Provided is an optical imaging device which improves the structure of an imaging unit drive mechanism for vibration correction in an imaging unit and can reliably correct the vibrations. An optical imaging device, wherein an imaging unit is displaced to correct the vibrations, and the imaging unit is supported on a stationary object by a total of four suspension wires. A first imaging unit drive mechanism and a second imaging unit drive mechanism are provided as a pair at two positions on either side of the optical axis L. In the imaging unit drive mechanisms, imaging unit drive magnets, are held on the imaging unit side, which is the movable side, and imaging unit drive coils, are held on the stationary object side. | 04-28-2011 |
| 20110103782 | OPTICAL UNIT WITH SHAKE CORRECTING FUNCTION AND PHOTOGRAPHIC OPTICAL DEVICE - Provided is a photographing optical device, which is able to reliably correct an unintentional movement by hand of a user by improving the constitution of a camera unit driving mechanism for correcting the deflection of a camera unit. In order that a camera unit is made to be rocked to correct the unintentional movement, a photographing optical device includes a first camera unit drive mechanism and a second camera unit drive mechanism, which are so disposed at two side portions sandwiching a pivot portion therebetween as to make a pair. In these camera unit drive mechanisms, camera unit driving magnets are held on the side of the camera unit as a movable body side, and camera unit driving coils are held on the side of a stationary body. The camera unit is pushed toward the pivot portion by a gimbal spring, which is provided with a plurality of arm portions extending mutually in the same circumferential direction. | 05-05-2011 |
