Abstract
An endoscope has a first bending portion and a second bending portion. The first bending portion is the distal portion of an elongated insertion member, and the second bending portion is located at the proximal end of the first bending portion. The dimension of the second bending portion in the longitudinal axis of the insertion member is smaller than the dimension of the first bending portion therein. The endoscope includes a hand-held unit having a control section that is used to bend the first bending portion and second bending portion. The control section of the hand-held unit has an angling knob that is used to bend the first bending portion, and a second angling lever that is used to bend the second bending portion.
