Imaging apparatus

摘要

An imaging apparatus includes a front lens group, which constitutes part of an imaging optical system, at a fixed position with respect to an optical axis direction, wherein the front lens group includes a front lens element and a reflector and the reflector reflects light rays exiting from the front lens element; a movable lens group provided closer to the image plane side than the front lens group and movable along the optical axis; a support member which supports the reflector; a movable frame which supports the front lens element and is supported by the support member to be movable along a plane orthogonal to the optical axis of the front lens element; and a driver which drives the movable frame in the plane, in accordance with vibrations applied to the photographing optical system, to reduce image shake.

1. An imaging apparatus comprising:
a front lens group, which constitutes part of an imaging optical system of said imaging apparatus, provided at a fixed position with respect to an optical axis direction, wherein said front lens group includes at least one front lens element, and a reflector, in that order from an object side, wherein said reflector reflects light rays exiting from said front lens element; a movable lens group, which constitutes another part of said imaging optical system, provided closer to the image plane side than said front lens group and movable along the optical axis; a support member which supports at least said reflector of said front lens group; a movable frame which supports said front lens element of said front lens group and is supported by said support member to be movable along a plane orthogonal to the optical axis of said front lens element; and a driver which drives said movable frame in said plane, in accordance with vibrations applied to said photographing optical system, to reduce image shake on said image plane, wherein at least said reflector is stationary relative to said movable frame during driving of said movable frame by said driver.
