Embodiment Construction
[0056] Hereinafter, embodiments of the optical unit with shake correction function of the present invention will be described with reference to the drawings.
[0057] In the following description, the three directions orthogonal to each other are the X-axis direction, Y-axis direction, and Z-axis direction. In the static state, the optical axis L (lens optical axis / optical axis of the optical element) is assumed. It is arranged along the Z axis. In addition, in the jitter in each direction, rotation around the X axis corresponds to so-called pitch (pitch), and rotation around the Y axis corresponds to so-called yaw (yaw). In addition, mark +X on one side in the X-axis direction, -X on the other side, +Y on one side in the Y-axis direction, and -Y on the other side, on one side in the Z-axis direction (photographed The body side / front side in the optical axis direction is marked with +Z, and the other side (the side opposite to the subject side / the back side in the optical axis d...

An optical unit with a shake correction function reliably restricts movement of a movable body in an optical axis direction when a drop impact or the like occurs, suppresses transmission of the impactto an imaging element, and achieves miniaturization. The optical unit with a shake correction function may include an optical module having an optical element and an image pickup element, a movable body holding the optical module, a swing support mechanism swingably supporting the movable body, a fixed body supporting the movable body through the swing support mechanism, a shake correction drivemechanism structured to swing the movable body, and a stopper mechanism structured to restrict a movable range of the movable body. The stopper mechanism may include a spacer member in the movable body which includes a stopper protruded part extended to an opposite side to an object to be photographed with respect to the image pickup element, and a stopper member to abut with the stopper protrudedpart of the spacer member. The spacer member may be fixed to a member different from the optical module in the movable body.
Description
Technical field [0001] The present invention relates to an optical unit with a shake correction function that performs shake correction of an optical module installed in a portable terminal with a camera or the like. Background technique [0002] In optical units used in optical equipment such as imaging devices installed on portable terminals, dash cams, unmanned helicopters, etc., in order to suppress the interference of captured images caused by jitter, an optical module has been developed to offset the jitter The function of correcting jitter by swinging. In this shake correction function, a structure is adopted in which an optical module including an optical element is swingably supported with respect to a fixed body constituted by a frame of an optical device, and the optical module is swung in accordance with the shake by a shake correction drive mechanism. [0003] The driving mechanism for shake correction is configured to include a magnet and a coil, and to drive the opt...
