Problems solved by technology

[0004] However, in the anti-vibration mechanism disclosed in Japanese Laid-Open Publication No. 2012-118336, the prism is rotated by rotating the two rotation shafts with the motor and the gear, and the deviation of the optical axis cannot be suppressed with a simple structure.

Abstract

In an optical unit, a first swing mechanism swings a holder with reference to the y-axis direction, and a second swing mechanism swings the holder with reference to the z-axis direction. A case has a first recess that accommodates at least a part of a first protrusion of the holder and a second recess that accommodates at least a part of a second protrusion of the holder. The first recess has a first side surface located on one side in the y-axis direction of the first protrusion, a second side surface located on the other side in the y-axis direction of the first protrusion, and a bottom surface. The second recess has a first side surface located on one side in the y-axis direction of the second protrusion, a second side surface located on the other side in the y-axis direction of the second protrusion, and a bottom surface.

Description

technical field [0001] The invention relates to an optical unit. Background technique [0002] When shooting still images or moving images with a camera, image blur sometimes occurs due to hand shake. Therefore, a hand-shake correction device for achieving clear photography in which image blur is prevented has been put into practical use. The hand shake correction device corrects the position and posture of the camera module according to the hand shake when the camera is shaken, so that the inconvenience caused by the hand shake can be eliminated. [0003] In addition, in order to miniaturize the camera module, there are known camera modules of a curved zoom system equipped with various lens groups and prisms, and studies have been made to eliminate hand shakes of camera modules of the curved zoom system (for example, refer to Japanese Unexamined Patent Application Publication No. 2012-118336). Japanese Laid-Open Publication No. 2012-118336 describes a vibration-proof mec...
