1. an electrically bent endoscope, is characterized in that, this electrically bent endoscope has:

  • Bending section, it is arranged on the insertion section;

    Crooked driver element, it has a plurality of structure members that make described bending section flexure operation;

    Crooked power unit, it drives described crooked driver element;

    The case of bending detecting unit, it detects the case of bending information of described bending section by the action message of surveying described crooked driver element;

    Indicating member, its output make the crooked indication information of described bending section bending;

    AndThe flexure operation control unit, it is made of a plurality of logical blocks independently, and controls so that the case of bending information of the crooked indication information of described indicating member and described bending section is consistent,This flexure operation control unit has speed controlling piece (201b), torque controll block (201c), station control block (201a), in the situation of this speed controlling piece (201b) akinesia, by change-over switch section (210b, 210c), only remove speed controlling piece (201b), (201a) resets the gain setting value with position control module, makes closed loop characteristic identical.
