Endoscope
First Claim
1. An endoscope comprising:
- (1) an optical lens unit including a lens frame having a rear end portion, and lens frame cover and a plurality of lenses attached to the lens frame; and
(2) an image sensor unit attached to an outer periphery of the rear end portion of the lens frame and comprising,(a) an electroconductive image sensor housing, one forward end portion of which is attached to the outer periphery of the rear end portion of the lens frame, the image sensor housing having a rear end portion and a recess formed there;
(b) an electric circuit section comprised of a solid-state image sensor located within the recess and having a plurality of lead-in pins, and electric component parts electrically connected to the lead-in pins;
(c) an electroconductive shield pipe attached at a forward end portion to the outer periphery of the rear end portion of the image sensor housing and having the rearwardly extending rear end portion, the shield pipe containing the whole electric circuit section therein;
(d) electroconductive cable fixing means located behind the electric circuit section and having through recess means, the cable fixing means being fixed to the rear end portion of the shield pipe with a pipe holder therebetween; and
(e) shielding wires inserted into the shield pipe through the recess means and each having an outer cover, external conductors and internal conductors electrically connected to the electric component parts or the lead-in pins.
