Abstract
An electric bending endoscope apparatus includes an electric bending endoscope, a bending control device for controlling a bending direction and the amount of bending of a bending portion based on a bending instructing signal outputted from a portion for instructing a bending operation in the electric bending endoscope, an image processing device for generating an observing image captured by the electric bending endoscope to a video signal, and a display device for displaying the video signal generated by the image processing device as an endoscope image, wherein the electric bending endoscope includes a bending driving portion for bending the bending portion arranged at an inserting portion, a bending motive portion for driving the bending driving portion, a portion for restoring transmission and disconnection of driving force that reversibly switches a status for transmitting the driving force by transmitting the driving force of the bending motive portion to the bending driving portion and a status for disconnecting the driving force, a portion for detecting a bending status which detects an operating status of the bending driving portion and detects the bending status of the be…
