<P>PROBLEM TO BE SOLVED: To provide an endoscope apparatus which can easily and reliably detect optical transmission loss caused by disconnection of optical fiber or the like. <P>SOLUTION: The endoscope apparatus is structured as follows: a plurality of illumination windows for emitting illumination light, and an observation window for observing an object are set up to the tip of an endoscope-inserting part to be inserted into the object. The endoscope apparatus includes: a light sauce; a light-guiding member the light emitting end of which is set up toward the illumination windows and which functions as a light pass through which output light from the light sauce is transmitted to the illumination windows through the endoscope-inserting part; and an illumination light-controlling means for controlling the lighting of the light sauce by switching between a normal lighting pattern for making endoscopic observation, and a loss-confirming lighting pattern for confirming the optical transmission loss of the light-guiding member and different in control from the normal lighting pattern so as to control the lighting of the light sauce. <P>COPYRIGHT: (C)2012,JPO&INPIT |
