<p>PROBLEM TO BE SOLVED: To provide an optical apparatus constituted of two frames performing a relative movement with each other capable of reducing a deflection of a flexible printed board provided therebetween while increasing the distance of the relative movement.SOLUTION: The optical apparatus having lenses comprises: a first frame; a second frame held movably with respect to a first frame in a direction of optical axis; and a flexible printed board mounted on the first frame and the second frame. The second frame has: a transmission region for allowing a beam of light coming through the lenses to pass therethrough; and a wiring plane which is positioned at the image side different from the transmission region and is generally perpendicular to an optical axis of the lenses. The flexible printed board is fixed to the wiring plane on the second frame by a support, and a wire is laid from the support along the wiring plane on the second frame and is bent and pulled out from the wiring plane on the second frame. When the second frame is moved toward the object, a part of the flexible printed board with the wire which is laid along the wiring plane on the second frame separates away from the wiring plane.</p> |
