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.
