Abstract

An imaging apparatus of the present invention comprises an elastically-deformative band-like flexible printed-circuit (FPC) board having one end thereof fixed to a lens holding frame 4 supported movably in an optical-axis direction O and capable of electrically connecting the main unit of the imaging apparatus with the lens holding frame, and an FPC board take-up mechanism for fixing and supporting the other end of the FPC board and applying a tension to the FPC board so that the FPC board will not loosen. The FPC board take-up mechanism feeds or winds the FPC board according to advancement or withdrawal of the lens holding frame. Using this apparatus, a space within a lens barrel to be occupied by the FPC board for electrically connecting the main unit with the lens holding frame can be minimized. Furthermore, the present invention can be implemented in an imaging apparatus in which a lens holding frame makes a long stroke.
