| description | PURPOSE:To provide an article-existence judgment apparatus in which the existence of even a low or transparent article can be judged precisely and which is not affected by the contamination or the like of a conveyor. CONSTITUTION:A linear optical beam is projected onto a stand 11 which conveys an article 10, and light-cutting lines 23a, 23b are formed. The shape of the light-cutting lines 23a, 23b is changed depending on whether the article 10 does not exist on the stand 11 and whether it exists. Consequently, the light- cutting lines 23a, 23b are imaged by a video camera 24 or the like, and a change in the shape is detected. Thereby, the existence of the article can be detected. |
