IPC: G07D7/00
Filed: 1992-12-28
Abstract: PURPOSE:To save the labor for office work wherein paper sheet, etc., is handled by reading a code printed on the paper sheet by the pattern recognition of the output of an image sensor and then automatically recording a printed surface. CONSTITUTION:A read controller 20 sends its output to an image sensor driving circuit when the code printed on paper money 14 passes by an image sensor 17 to energize the image sensor 17. The image sensor 17 converts the code printed on the paper money 14 into an electric signal. At this time, the read controller 20 confirms the arrangement direction of the paper money 14 which is moved on the basis of information sent out of a discrimination sensor 16 and when the arrangement direction is opposite, the kind of money of the paper money 14 and the image of the code are stored in a storage device after the output of the image sensor 17 is converted. Then the storage device stores the output of the image sensor 17 and sends it out to a printing device 19. The printing device 19 prints the code, printed on the paper money 14, and the kind of the paper money 14 on the basis of the read controller 20.
