Abstract

PURPOSE:To maintain the best lighting state at all times, by allowing a plate type stop to shield the incidence end of one light guide fiber arranged at the tip side of a tip hard part earlier than the incidence end of the other light guide fiber. CONSTITUTION:The diaphragm 113 and a condenser lens 2 are arranged in front of a xenon lamp 1, light guides (LG) 105b and 105a are arranged above before the condenser lens 2 respectively, and LGs 105b and 105a are arranged below and above an observation window 103 respectively. Further, when the diaphragm is put in operation shielding the lower half part of the condenser lens 2, projection light from the condenser lens 2 is projected only from the projection end of the LG 105b. Here, the LG 105b projects the light slightly above the vertical surface of the tip hard part 101, so when an observation is made through the observation window 103, an affected part can be observed in a uniform light distribution state at positions P2 and Q2. Consequently, the best lighting state is maintained at all times.
