Patent ID: 7435215

Claim:
An endoscope comprising: an elongated flexible inserting portion; an operating portion which is mounted on the proximal end side of the inserting portion and which has a grip portion capable of being gripped by an operator; an objective optical system which is mounted to the distal end side of the inserting portion and which can transmit an optical image of a subject into the inserting portion; image guiding fibers which can transmit the optical image incident from the distal end side via the objective system to the proximal end side and which is inserted into the inserting portion so that the proximal end side extends in the operation portion from the inserting portion; an optical image output portion which constitutes the proximal end side of the image guiding fibers and which outputs the optical image transmitted from the distal end side; an image pick-up unit having an image pick-up device for picking up the optical image transmitted from the optical image output portion; and a plate frame provided in the operating portion for suppressing a deforming of the operating portion, the plate frame having a notch portion to mount the image pick-up unit at a position at which the optical image transmitted by the optical output portion can be picked up in the operating portion.
