1. An electric bending endoscope apparatus comprising:

  • an electric bending endoscope having a bending portion at an inserting portion thereof and a bending driving portion with a plurality of members for bending the bending portion;

    a bending motive device which drives the bending driving portion;

    a bending angle detecting portion which detects an operating status of the bending driving portion and detects a bending status of the bending driving portion;

    a bending operation instructing portion having an instructing member which outputs a bending instructing signal for bending the bending portion, the bending operation instructing portion matching an instructing status of the instructing member to the bending status of the bending portion with a positional relationship;

    a bending control device comprising a driving signal generating portion which generates a driving signal outputted to the bending motive device based on the bending instructing signal outputted from the bending operation instructing portion and information on a bending position indicating the bending status detected by the bending angle detecting portion;

    a portion for restoring transmission and disconnection of driving force which reversibly switches a transmitting status for transmitting the driving force of the bending motive device to the bending driving portion or a disconnecting status; and

    a positioning portion which relatively matches the instructing status of the instructing member in the bending operation instructing portion to the bending status of the bending portion.
