Abstract

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.
