Abstract:
1. A casing for a capsule endo scope which includes a first casing that has a bottomed cylindrical shape and retains an imaging element therein and a transparent second casing that has a cylindrical portion and a hemispheric portion having the same outer diameter as an outer diameter of the first casing and engages with the first casing, in which at least an illumination system and a lens located on an outermost side are positioned inside the second casing, the casing comprising: a base portion having a planar shape; a holding portion provided at a center of the base portion so as to protrude in a direction orthogonal to a principal surface of the base portion and hold the capsule endoscope; a plurality of abutting portions each protruding from the holding portion and abutting on at least a portion of an outer surface of the hemispheric portion of the second casing, wherein each of the plurality of abutting portions is located inside an optical viewing angle of the capsule endoscope and does not contribute to generation and/or use of an image captured by the capsule endoscope to realize alignment in a longitudinal direction of the capsule endoscope; and an index for alignment of the abutting portions with respect to an area of the outer surface of the hemispheric portion of the second casing, on which the abutting portions abut.
