PROBLEM TO BE SOLVED: To provide an endoscope apparatus capable of performing high speed long-distance communication with an endoscope body part stably even when there are increases in kinds and the number of sensors mounted on an endoscope tip part.SOLUTION: An endoscope apparatus includes an insertion part 3 in which an imager 11 is provided to a tip part 2, sensors 12-14 for detecting a state of the tip part 2, and a body part 4 for receiving an image signal and a detection signal, and transmitting a control command signal to the sensors 12-14, etc. The tip part 2 includes an overlapping processing part 16 for overlapping the image signal and the detection signal, a light module 19 for subjecting an electric signal to electrooptical conversion, and a communication control part 17 for controlling input/output of the signal to the sensors 12-14, etc. The body part 4 includes a light module 41 for subjecting an optical signal to photoelectric conversion, and a separation processing part 42 for separating the electric signal into the image signal and the detection signal. The insertion part 3 includes an optical fiber 31 for transmitting the optical signal, and an electric wire 32 transmitting the control command signal.SELECTED DRAWING: Figure 1 |
