    摘要： An electronic endoscope apparatus includes: an image pickup apparatus mounted at a distal end portion of an insertion portion; an operation portion provided consecutively at the insertion portion, with a frame member incorporated therein; and an electrical cable extended from the operation portion for connection with an external device. In the electronic endoscope apparatus, the frame member has a circuit board portion which establishes electrical connection between shields of the insertion portion and the electrical cable, and on which various electronic parts for exchanging signals with the image pickup apparatus are mounted. In spite of the arrangement of the image pickup apparatus that can acquire high-quality images at a distal end portion of the insertion portion, a size of the apparatus, in particular, a diameter of the insertion portion, can be prevented from being increased.

    摘要： An image pickup apparatus of the present invention varies optical properties by moving a part of lenses of an objective lens, and includes a solid-state image pickup device unit that is disposed at a rear-end section and that subjects a subject image to photoelectric conversion, a fixed lens frame that retains the objective lens that is disposed in front of the solid-state image pickup device unit, a movable lens frame that retains the part of lenses that moves along a photographing optical axis O inside the lens frame, and an actuator having one end connected to the movable lens frame and that moves the movable lens frame forward and backward. The actuator includes a rigid member provided so as to extend to the vicinity of the rear end at which the solid-state image pickup device unit is disposed and a shape memory alloy that is coupled to the rigid member.
