Patent number: 10996485Abstract: A laser pointer may include a laser light emitter that emits a laser beam, a housing accommodating the laser light emitter; a vibration detection sensor that detects a vibration produced in the housing, a shake correction mechanism that changes a direction of the laser beam emitted by the laser light emitter, and a controller that controls the direction of the laser beam, which is changed by the shake correction mechanism, into a direction so as to offset the vibration detected by the vibration detection sensor. The controller may be configured to calculate a frequency of the vibration; calculate a movement amount of the vibration; determine whether a vibration applied to the housing is caused by a hand-shake based on the frequency of the vibration and the movement amount of the vibration; and activate the shake correction mechanism in response to a determination that the vibration is caused by a hand-shake.Type: GrantFiled: February 26, 2019Date of Patent: May 4, 2021Assignee: NIDEC SANKYO CORPORATIONInventors: Takeshi Sue, Masato Gomyo, Ryoji Komatsu

Patent number: 10728456Abstract: An optical unit may include a movable body having an optical element, a support body movably supporting the movable body, a detecting part to detect a variation of a tilt of the movable body, a drive mechanism to change a tilt of the movable body, an output part to connect with an external device, a control part to control the drive mechanism based on the variation detected by the detecting part to correct the tilt by the drive mechanism, and an output control part to create information regarding the variation as a signal equivalent to drive signal data which are outputted to the drive mechanism for correcting the tilt from the control part and output the information to the external device during a period when the control part makes the drive mechanism correct the tilt. An optical system comprises the optical unit and the external device.Type: GrantFiled: May 15, 2018Date of Patent: July 28, 2020Assignee: NIDEC SANKYO CORPORATIONInventors: Yuta Otomo, Ryoji Komatsu

Patent number: 9185296Abstract: Provided is an optical unit with a blur correction function, wherein even when a photoreflector and a drive mechanism for blur correction are provided in a movable module provided with an optical element, sizes in an optical axis direction and a direction crossing the optical axis direction can be prevented from increasing. In an optical unit (100) with a blur correction function, a drive mechanism (500) for blur correction is provided between the outer peripheral surface of an image capturing unit (1) and a fixed body (200) (upper cover (250)), and a first photoreflector (580) and a second photoreflector (590) are provided between a bottom portion (substrate (15)) of the image capturing unit (1) and the fixed body (200) (lower cover (700)), between which a swing support (180) is provided.Type: GrantFiled: January 6, 2015Date of Patent: November 10, 2015Assignee: NIDEC SANKYO CORPORATIONInventors: Tatsuki Wade, Shinroku Asakawa, Shinji Minamisawa, Toshiyuki Karasawa, Katsushige Yanagisawa, Yoshihiro Hamada, Hayato Naito, Ryoji Komatsu, Hisahiro Ishihara
