PROBLEM TO BE SOLVED: To secure excellent illumination to a body to be observed even when the battery of a using LED light source runs out during observation or when there is a failure in the LED light source or the driving circuit or the like.
SOLUTION: A plurality of LEDs 26 inside the LED light source 21 for illumination are divided into a first set LED part 21a, a second set LED part 21b and a third set LED part 21c, batteries 23a, 23b and 23c are connected to each of the three set LED parts 21a-21c, and they are switched by a changeover operation switch 24 and switching circuits 22a-22c and used. At the time, the voltage of the battery during power feed at present or the like is detected, and when the voltage declines to a prescribed value or lower, an alarm is displayed or it is automatically switched to the other battery and the light emitting diode of the other set.
