Title:
ENDOSCOPE
Document Type and Number:
WIPO Patent Application WO/2018/079077
Kind Code:
A1
Abstract:
Provided is an endoscope comprising an imaging device 20 at the distal end of an insertion part which can be inserted into a body cavity. The imaging device is provided with the following: a lens barrel 22 for holding an imaging lens 23; an image sensor 21 that photoelectrically converts imaging light incident on an image receiving surface thereof via the imaging lens, the outer periphery of the image receiving surface of the image sensor being a rectangular shape; and a sensor holder 40 that holds the image sensor in a state in which the image receiving surface intersects the lengthwise direction of the insertion part. The sensor holder has three separate wall parts 42 each covering one of three side surfaces of the image sensor. In an XY plane orthogonal to the lengthwise direction of the insertion part, the length of a gap in the X-axis direction on the plane between adjacent wall parts of the three wall parts is equal to the length of a gap in the Y-axis direction between adjacent wall parts of the three wall parts. Furthermore, the height of each of the three wall parts 42 is 1.5 to 3 times the length of the gap.
