The first bending portion is the distal portion of an elongated insertion member and has a plurality of joint pieces concatenated so that the joint pieces can rotate freely. The second bending portion is located at the proximal end of the first bending portion, and has a plurality of joint pieces concatenated so that the joint pieces can rotate freely. The hand-held unit is located at the proximal end of the insertion member, and has a control section that is used to bend the first bending portion and second bending portion. In the endoscope, 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.

Abstract: An endoscope system includes an endoscope, two control apparatuses, electric cables, and two electric connector receptacles. The endoscope has a connector unit, which includes a light source connector to be coupled to a light source apparatus, fixed to the proximal end of a universal cord extending from an operation unit. The two control apparatuses electrically control the endoscope. The electric cables electrically link the control apparatuses and the endoscope. The two electric connector receptacles are included in the connector unit of the endoscope. Connectors attached to the electric cables are coupled to the two electric connector receptacles. When the connector of one of the electric cables is mounted on a first electric connector receptacle of the two electric connector receptacles, the direction in which the connector is oriented to be mounted is orthogonal to the direction in which the light source connector is oriented to be coupled to the light source apparatus.

Abstract: In an endoscope of the present invention, while a cover indicator on a distal cover is aligned with a scope indicator on a main distal part, the distal cover is put on the main distal part in an axial direction at a certain insertion angle. Thereafter, the distal cover is rotated while being thrust in the axial direction. The stoppage of a locking convex part of a hook of the main distal part by a claw of a reinforcement member is released, and the locking convex part of the hook is positioned in a locking ditch of the reinforcement member. The head of the hook is constrained to move in the axial direction by means of a main distal cover that is an elastic member and the claw. The locking convex part is then fitted into the locking ditch reliably. Consequently, the distal cover can be fixed to the main distal part readily, freely detachably, and reliably with high positioning precision.
