Abstract
Abstract An image input apparatus in which a lens is exchangeable has a mount for mounting a lens and a member for adjusting a mounting position of the lens. The mount and the member are each constituted as a separate member, and are arranged such that the apparatus is, at the same time, capable of performing adjustment of the angle between an optical axis of the lens and a surface of a CCD.
