<p>A transparent liquid testing apparatus for recognizing the boundary between a transparent liquid to be applied to a multi-block product on a base and the base and automatically test the coating state of the transparent liquid without being influenced by the background of the base. The surface of the transparent liquid is used as a mirror surface to form there the projected image by an illuminating light source (2). The projected image is picked up by cameras (41 to 44), and the picked-up image is analyzed by an image processor (8), whereby the displacement from a predetermined coating position of the transparent liquid and the spread of its liquid surface are tested.</p> |
