PROBLEM TO BE SOLVED: To provide a classification device for identifying articles at an automatic checkout counter.SOLUTION: A classification device 2 comprises: a memory unit 5 capable of storing digital reference signatures each of which is used for identifying a corresponding article; and a processor 6 connected to the memory unit 5. The classification device 2 further comprises a spectroscopic sensor 7 connected to the processor. The spectroscopic sensor 7 is placed so as to determine the measured signature of an article 3 if the article 3 is placed before, above or behind a measuring sensor 4. The processor 6 is placed so as to compare the measured signature with a digital reference signature in order to identify the article 3 as the identification of an existing article in the memory unit 5.SELECTED DRAWING: Figure 3 |
