Abstract:
A correcting device for correcting a tremble of a focused image comprises:a correction optical system for correcting a tremble of an optical axis in an optical device; a driving frame, holding said correction optical system, that can be moved in a predetermined direction on a plane perpendicular to said optical axis; a driving mechanism that includes a shaft having a central axis which is parallel to said predetermined direction, said shaft being linearly driven shaft along said central axis; and a transmitting mechanism that engages both ends of said shaft in order to transmit the linear movement of said driven shaft to said driving frame, said transmitting mechanism including two projecting portions that project from said driving frame along said optical axis so as to face the corresponding ends of said shaft, and a pressing member, provided on at least one of said two projecting portions, that causes said shaft to be engaged at both ends by pressing said shaft against the other of said two projecting portions.
