<p>PURPOSE:To decide whether the reading is already confirmed or not and at the same time to improve the service performance by providing an imaging mechanism at a part of a symbol reading part and carrying out the imaging as soon as the reading is confirmed. CONSTITUTION:An imaging mechanism 3 is provided at a part of a symbol reading part 2 of a reader 1 for symbols including bar codes, etc. The reader 1 is pressed to a bar code sheet, and the part 2 reads optically the contents of the bar code. The mechanism 3 is actuated as soon as the reading is through with the part 2, and a mark 4 is printed on the bar code sheet with attachment of a confirmation symbol showing the reading is over. In such a way, it is possible with each article to decide that the reading is through or not. This suppresses psychologically the occurrence of dishonest acts including shoplifting, etc. When the mark 4 shows a date, the returns of articles can be carried out properly. This improves the service performance to customers.</p> |
