Abstract
The endoscope system comprises a endoscope in which a bendable portion is motor bendable; an operation switch for giving an instruction as to a bending amount; a motor for bending the bendable portion in accordance with a bending instruction signal; a detection portion for detecting the bent state of the bendable portion; a first driving power generating portion which generates power for driving the motor in accordance with a difference between an instructed bending amount fed via the operation switch and a value representing the bending state of the bending portion and given by the detection portion; a second driving power generating portion for generating a pulse driving power having a predetermined magnitude; and a control portion whose control includes selecting one of the first and second driving power generating means depending on said difference, and causing the thus selected means to drive motor so as to bend the bendable portion.
