<p>PROBLEM TO BE SOLVED: To provide a scanning endoscope system capable of accelerating the recovery the transmissivity of a light receiving fiber without uselessly increasing the diameter of the insertion part.SOLUTION: A scanning endoscope system comprises: a scanning endoscope which has, at the tip of an insertion part, an end part of the light emission side of a light guiding fiber, an actuator part for swinging the end part of the light emission side, and an end part of the light incidence side of a light receiving fiber into the light incidence surface of which external light is entered; a reflection member capable of reflecting emission light emitted from a tip surface of the tip; and a contact member capable arranging the tip surface contactingly on a surface the contact member. The scanning endoscope system also includes: a light reflector configured such that at least part of the emission light is reflected off the reflection member and enters the light incidence surface while the tip surface is arranged contactingly on the surface of the contact member; and a control part which swings the end part of the light emission side such that a circular orbit is drawn with the longitudinal axis of the insertion part as the center while the tip surface is arranged contactingly on the surface of the contact member.</p> |
