According to the present invention, an endoscope system having an insertion member thereof wound about a drum comprises an electronic endoscope, a drum, an angling input unit, a motor-driven angling unit, a camera control unit, a motor-driven angling control circuit unit, and a stowage case. A bending section included in an insertion member of the electronic endoscope is motor-driven to bend, and a solid-state imaging device is incorporated at the tip of the insertion member. The insertion member is wound about the periphery of the drum. The angling input unit is separated from the electronic endoscope, and used to enter a direction of bending in which a user wants to bend the bending section. The motor-driven angling unit is incorporated in the drum, and includes a driving source for driving a driving mechanism that drives the bending section. The camera control unit controls the solid-state imaging device, and includes a signal processor for processing an electric signal sent from the solid-state imaging device to generate a video signal. The motor-driven angling control circuit unit controls the movement of the bending section. The drum is rotatably stowed in the stowage case freely.

Disclosed is an industrial endoscope system having a rotary treatment member, attached to a hard top part at a distal end of an insertion unit, for effecting a treatment such as grinding by rotating this treatment member itself. The system includes a moving means for making a distal end of the treatment member movable in the axial directions of the insertion unit. This easily leads the treatment member to a target position via a lead-in port of an engine; or the treatment member can be set in a position suitable for the treatment.

A borescope apparatus having a borescope and a pressurized fluid supply device. The borescope has an operation unit and an insertion unit. The insertion unit comprises a bending tube portion, a jet port member coupled to a proximal end of the bending tube portion, and a flexible tube portion. The bending tube portion can be bent by operating the operation unit. The jet port member has a jet port. A pressuring fluid is supplied from the fluid supply unit to the jet port member, and is ejected through the jet port. The flexible tube portion can be bent by a jet of the fluid from through the jet port independently of the bending tube portion.

Borescope apparatus

An endoscope tip is fittable with either (a) a first kind of objective part, having an objective optical system provided with a rotary adjusting mechanism or (b) a second kind of objective part having an objective optical system provided with no rotary adjusting mechanism. A non-rotary connecting mechanism is formed for the first kind of objective part and a rotary connecting mechanism is formed for the second kind of objective part so that the connecting mechanism may not loosen when there is a rotary adjustment of the objective in order to focus the same.
