PROBLEM TO BE SOLVED: To provide an apparatus for performing a work operation for processing a finished article and protecting a machine using a camera unit which can be quickly and easily assembled with reduced individual adjustment of optical components or without individual adjustment of the optical components.SOLUTION: A light source and a camera unit are configured to be attached to a first mechanical part so as to simultaneously operate with the first mechanical part. The camera unit includes: an objective lens body 42 having at least one lens element 44, an electronic image sensor 66 which is arranged in a component support body 64, a coupling part 68 with one-piece body which joins the objective lens body 42 and the component support body 64 at the prescribed relative positions; and an aperture stop 70. The one-piece body is installed in the state of being fixed to the component support body 64. With this, the aperture stop 70 is held at the prescribed position without individual adjustment with respect to the electronic image sensor.SELECTED DRAWING: Figure 3 |
