Abstract

An endoscope system of the present invention is provided with: a long, thin inserted portion that includes an illuminating portion that emits an illumination light beam toward an imaging subject, an image-acquisition portion that acquires an image of the imaging subject, and a channel; and an illumination device that is disposed in the channel, wherein the illumination device includes an illuminating portion that emits, toward the imaging subject, an illumination light beam that has a divergence angle that is smaller than that of the illumination light beam and for which the image-acquisition portion has sensitivity, and a pulling member that extends to outside the channel from a base end of the illuminating portion, and wherein the illuminating portion can be removed from the channel by pulling the pulling member.

Dependent claims

An endoscope system comprising:

an inserted portion that includes a first illuminating portion that emits a first illumination light beam toward an imaging subject, an image-acquisition portion that acquires an image of the imaging subject, and a channel that passes therethrough in a longitudinal direction;
an illumination device that includes a second illuminating portion that is insertable in the channel and that emits a second illumination light beam toward the imaging subject, and a pulling member that is connected to a base end of the second illuminating portion and that extends to outside from a base end of the channel;
and
a protrusion that is fixed to an inner circumferential surface of the channel,
wherein the second illuminating portion is fixed at a predetermined position in the channel by a part of an outer circumferential surface of the second illuminating portion contacting the protrusion, and emits the second illumination light beam, which has a divergence angle that is smaller than that of the first illumination light beam and for which the image-acquisition portion has sensitivity, and
wherein the protrusion has elasticity.
