Abstract
An operational remote controller integrates a joystick for bending a bending portion of an inserted portion in an endoscope. A bending lever stands on the joystick. For every automatically returning of the bending lever to a neutral position, a CPU of the operational remote controller detects the neutral position and sets an insensitive band within a predetermined range of the neutral position. Thus, the insensitive band can be set within a relatively narrow range irrespective of variation of neutral positions. The CPU supplies positional information of the bending lever to a control circuit for controlling a motor drive circuit. The control circuit controls a motor drive circuit based on the supplied positional information, and the motor drive circuit drives a motor to bend the bending portion of the inserted portion.
