PROBLEM TO BE SOLVED: To make it possible to precisely recognize whether the position of an element substrate is right or wrong by a method wherein illumination which is used to recognize a recognition pattern is projected from the side end face of the element substrate, the part of the recognition pattern is made dark color, parts other than the part are made bright color and the position of the pattern is recognized on the basis of binary recognition. SOLUTION: A recognition pattern M on an element substrate A composed of a glass epoxy resin blank is projected from the side end face (a) of the element substrate A by means of illumination by a projector 1, the place of the recognition pattern M is made dark color by a recognition camera 2 which is situated just above the recognition pattern M, parts other than the place are made bright color, and the position of the recognition pattern M is recognized on the basis of binary recognition. As a result, when the recognition camera 2 is connected to a monitor, the position of the recognition pattern M can be recognized precisely, a recognition signal is sent to an element working machine, and the operation and the stop of the working machine can be controlled. As a result, whether the position of the element substrate A is right or wrong can be detected precisely. |
