Abstract
In response to the operation of a bending operation switch, a controlling circuit switches on/off a plurality of transistors of a driving circuit, controls the polarity of a voltage applied to a motor or does not apply the voltage and, on the other hand, controls the voltage applied to the motor to be on/off while monitoring the rotating speed of the motor through an encoder to thereby drive and control the motor at a predetermined speed which can be variably set steppedly so that an endoscope bendable part may be bent at a fixed speed.
