Abstract

PURPOSE:To make the eye-ground easy to see by automatically inserting a variable filter into an optical path after the operation of a fluorescent observation and photographing start switch later than an exciting filter. CONSTITUTION:In the case of performing fluorescent observing and photographing, an F set switch 20 is turned on simultaneously with injection of a fluorescent agent, then a driver 21 is operated to energize a solenoid 17 which in turn automatically inserts an exciting filter 16 into a lighting optical path simultaneously with the operation of the F set switch 20. On the other hand, after a constant time since the operation of the switch 20, a driver 24 is operated by the effect of a delay circuit 23, by which a solenoid 19 is energized to automatically insert a variable filter 18 into an observing and photographing optical path after a constant time since the operation of the switch 20.
