    摘要： A bend section is disposed on an insertion section. A rotary body, on which a proximal end portion of a wire for a bend operation, which has a distal end portion connected to the bend section, is rotatably supported in a large-diameter section. Driving force transmission portion, which converts linear movement of a working shaft that is operable in a linear direction to rotational movement of the rotary body, is provided in the large-diameter section. A driving source unit is detachably coupled to the large-diameter section on the proximal end side of the insertion section. The driving source unit is provided with operation section which linearly moves the working shaft, in accordance with an operation of a driving shaft that operates in a linear direction by a driving force from a driving motor.

    摘要： An electric bending endoscope comprises a bending portion arranged to an inserting portion, a bending driving unit and a buffering member. The bending driving unit bends the bending portion, and includes a motor, a first unit and a second unit. The motor generates driving force for bending the bending portion. The first unit holds the motor. The second unit includes a driving force transmitting member. The buffering member connects the first unit to an outer member of the inserting portion, a connecting code and a switch. The buffering member absorbs external force generated during the operation of the electric bending endoscope.

    摘要： An electrically-bent endoscope includes a bend driving portion for bending a bending portion. The bend driving portion has a motor for generating driving force, a gear train for transmitting driving force generated in the motor, a sprocket for converting driving force of the motor to a back and forth movement of bending operation wires for bending the bending portion at the head portion of an inserting portion, and a clutch mechanism for connecting and disconnecting driving force transmitted from the gear train to the sprocket. The clutch mechanism includes a transmitting member for connecting and disconnecting the gear train and sprocket, a thrust mechanism for moving the transmitting member in the axial direction of the sprocket and a clutch operating member, connected to the thrust mechanism, for inputting instructions for connecting and disconnecting the gear train and the sprocket.
