ENDOSCOPE DEVICE

PROBLEM TO BE SOLVED: To provide an endoscope device relatively easy in operation, and capable of downsizing an external unit. SOLUTION: The inside of an endoscope 1 is provided with an LED 5 for emitting the illuminating light to an object, an objective optical system 4 on which the light of the object illuminated by the LED 5 is made incident, a light transmitting means 6 for transmitting the object light incident on this objective optical system 4 so as to be capable of forming an image, a half mirror 7 for dividing the object light transmitted by the light transmitting means 6 by the different optical axes, an eyepiece optical system 8 for forming an object image for observing the first divided object light divided by the half mirror 7, and an imaging means 10 capable of imaging the second divided object light divided by the half mirror 7. This endoscope device is composed of a first unit 25 detachably connected to this endoscope, and having a battery B capable of supplying electric power to the LED 5, a battery A capable of supplying electric power to the LED 5 and the imaging means 10, and a second unit 15 having an imaging signal processing part 16 for processing an image signal imaged by the imaging element 10.
