摘要： 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.

摘要： An endoscope shape detection system has a CPU included in a control unit. The CPU performs frequency sampling on digital data to calculate coordinates indicating the spatial positions of source coils incorporated in an insertion unit of an endoscope and of marker coils. An inserted state of the insertion unit of the endoscope is estimated based on the calculated coordinate data indicating the positions of the source coils. Display data based on which shape of the endoscope depicted is produced from the calculated coordinate data indicating the positions of the source coils, and output to a video RAM. Display data based on which marker coils are depicted is produced from the calculated coordinate data indicating the positions of the marker coils, and output to the video RAM. Consequently, the positions of the markers are depicted together with the shape of the endoscope. The positional relationship between the insertion unit of the endoscope and a patient's body can therefore be ascertained.
