Patent ID: 7125378

Claim:
An imaging system comprising: an optical-system holding member for holding an optical system to form an optical image of a subject; an imaging-device holding member for holding an imaging device to obtain the optical image formed by the optical system; a case for hermetically enclosing the optical-system holding member and the imaging-device holding member, the optical-system holding member and the imaging-device holding member being disposed in the internal space of the case, the optical-system holding member having a slide contact surface which is slidable on the inner wall of the case, a protrusion on the outer surface of the optical-system holding member coming into contact with a contact portion on the inner wall of the case to restrict the forward movement of the optical-system holding member, and the rear end, including the protrusion, of the optical-system holding member coming into contact with the imaging-device holding member to restrict the backward movement thereof along the optical axis; a hermetic connector for hermetically sealing the case, the hermetic connector being electrically connected to the imaging device; a power generator for generating a driving force to move either the optical-system holding member or the imaging-device holding member, the power generator being arranged in the case and generating a driving force based on an electric energy supplied thereto via the hermetic connector; and a driving-force transfer member for connecting the power generator and either the optical-system holding member or the imaging-device holding member to transfer the driving force of the power generator to either the optical-system holding member or the imaging-device holding member.
