A camera with shake correction mechanism according to the invention comprises: an image pickup device for picking up object light; shake detecting device for detecting a shake exerted to a camera body; a shake correction unit provided with a driving section for exerting a swing force for swinging the image pickup device in a direction perpendicular to the optical axis; a control board on which electronic components are mounted; and a flexible wiring member for electrically connecting the shake correction unit to the control board, wherein the shake correction unit and the control board are arranged at adjacent positions to each other in a direction of almost the same plane, while in an adjacent part of the two elements, a space part is set up that can accommodate the flexible wiring member in a bent state. According to this configuration, in the camera in which a shake correction unit and a control board are arranged at adjacent positions to each other in a direction of almost the same plane so that the thickness size is reduced in the optical axis direction, the flexible wiring member for electrically connecting the two elements can be wired in an optimal manner.

Camera with shake correction mechanism

The size of the openingof the shutter base plateis set, considering driving amounts of the image sensorand the low pass filterduring shake correction, so that the size of the openingin X-axis direction (Y-axis direction) is set equal to or larger than the sum of the size of the low pass filterand the maximum moving amount of the low pass filterin the X-axis direction (Y-axis direction). Specifically, the length Lx of the openingof the shutter base platein the X-axis direction, and the length Ly thereof in the Y-axis direction respectively satisfy the following equations:+2&#x394;+2&#x394;where X represents the length of the low pass filterin the X-axis direction, Y represents the length of the low pass filterin the Y-axis direction, &#x394;x represents the maximum moving amount of the low pass filterin the X-axis direction with respect to the centering position, and &#x394;y represents the maximum moving amount of the low pass filterin the Y-axis direction with respect to the centering position.

An apparatus comprising planet gears,which rotate in engagement with a pinion gear,that itself rotates integratedly with the rotating shaft,of a motor,such that the planet gears,rotate around the periphery of the rotating shaft,, a carrier,which rotates integratedly to match the rotation of the planet gears,while supporting the planet gears in free rotation, and a photoreflector,for detecting rotation by detecting a rotation detecting part comprising a reflecting surface,and a non-reflecting surface,provided on the exterior surface of the carrier

Rotation detection mechanism and an apparatus provided with same

A mechanism, for optically adjusting a deviation of image forming position, which is installed in a lens barrel, for example, of a camera. The mechanism includes a first image shake preventing afocal lens and a second image shake preventing afocal lens which are supported by a first lens frame and a second lens frames, respectively. Each frame has a shaft supporting portion generally parallel to an optical axis and a gear input portion, for swinging each frame about the shaft supporting portion, opposed to the shaft supporting portion with respect to the optical axis. The first and second lens frames move in a direction generally perpendicular to each other. Each gear input portion is driven by a driving gear which is directly fixed to an output shaft of a driving motor. The motor is installed in the direction which is parallel to the optical axis.

Lens barrel with optical system for preventing image shake

A camera capable of correcting a shake includes a shake amount detector for detecting a shake amount of an object light image on an exposure plane, a memory for storing data in connection with a shake due to operation of a shutter release member, a calculator for calculating a shake correction control value based on a shake amount detected by the shake amount detector after operation of the shutter release member and the data stored in the memory, and a controller for controlling the optical system in accordance with a calculated shake correction control value to correct the shake.
