Electric bending endoscope apparatus
First Claim
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.

Abstract
Driving force of a bending motor is transmitted to a sprocket via a clutch mechanism portion. The operation of a switching operation lever switches the clutch mechanism portion to a disconnecting/restoring status. A bending control device includes a bending angle calculating portion which calculates information on a bending status based on an output signal of a potentiometer, a motor driving signal generating portion which generates a driving signal for bending a bending portion, a JS-motor driving signal generating portion which calculates a position for an instructing status of a stick portion based on the information on the bending status and generates the driving signal for moving the stick portion to the position, and a calibration instructing portion which receives a position signal from a status detecting switch and which sends an instruction for outputting to a JS motor, the driving signal generated by the JS-motor driving signal generating portion. With the above construction, the calibration operation is easily performed in a freely bending status.
