Abstract: An endoscope includes an image pick-up device at a distal end part of an insertion part capable of being inserted into a body cavity. The image pick-up device includes a lens barrel that holds an imaging lens; an image sensor having a rectangular shape as an outer peripheral shape of the image reception surface on which imaging light incident via the imaging lens; and a sensor holder that holds the image sensor in a state where the image reception surface intersects a longitudinal direction of the insertion part. The sensor holder has a fitting part fitted to the lens barrel, and an extending wall part that extends in the longitudinal direction of the insertion part from the fitting part to cover at least a portion of the outer peripheral surface of the image sensor, and the fitting part and the extending wall part are integrally configured.

Abstract: Provided are an endoscope imaging device and an endoscope capable of adjusting a position of a fixed lens along an optical axis.
An endoscope imaging device includes: at least one movement group including a movable lens that is movable along an optical axis; a plurality of fixed groups including a fixed lens whose position is fixed with respect to the optical axis, and at least one of which is an adjustment group; a sensor that images an observation target; a lens drive portion that moves the movement group along the optical axis. The adjustment group includes a cylindrical holding part, and the holding part includes a grip part provided at one end part of the holding part and an end surface provided at the other end part opposite to the one end part in the optical axis direction. The grip part includes a projecting portion or a recessed portion whose diameter changes in a radial direction of the holding part, and the adjustment group is configured such that the end surface provided at the other end part of the holding part is disposed at a position spaced apart from the lens barrel body provided with a movement group, the fixed group, and the lens drive portion, or the fixed group in the optical axis direction, and the grip part is disposed at a position spaced apart from the lens barrel body or the fixed group in the optical axis direction and protrudes from the lens barrel body or the fixed group, and a side surface of the holding part is fixed to the lens barrel body or the fixed group.

Abstract: An endoscope includes an image pick-up-device at a distal-end-part of an insertion-part. The image pick-up-device includes a lens barrel holding an imaging lens; an image-sensor having a rectangular shape as an outer peripheral shape of an image reception surface on which imaging light incident via the imaging lens; and a sensor holder holding the image-sensor in a state where the image reception surface intersects a longitudinal direction of the insertion-part. The sensor holder has three independent wall-parts respectively covering three side surfaces of the image-sensor, and on an XY plane orthogonal to the longitudinal direction of the insertion-part, a gap length, in an X-axis direction on the plane between adjacent wall-parts of the three wall-parts and a gap length, in Y-axis direction, between the adjacent wall-parts are equal to each other. Additionally, the height of each of the three wall-parts is 1.5 times to 3 times the gap length.
