<p>PURPOSE:To reproduce a correct contour by making information read by an array into a matrix, and reproducing the contour and the internal information line of a paper pattern by calculating the matrix. CONSTITUTION:A scanning table 5 for scanning an array train executes constant speed scanning from the lower surface of a placing table 3 by a step motor or a servo motor, etc. After the finish of the scanning, correction is executed by a correcting means 6 according to the overlapping part of each array 4, a space between the arrays 4 and scanning speed in a scanning direction and the light emitting period of a light emitting element as so on, and after generating a signal free from overlapping, a scanned surface is divided into small parts, and the matrix information of '0' and '1' is substituted for the presence or the absence of the information, that is, whether the contour line and the internal information line 2 of the paper pattern 1 exist or not by a converting means 7. Then, by inputting it in an arithmetic means 8, the contour is reproduced as the contour, and besides, the internal information line 2 is reproduced as the internal information line. Thus, it is possible to read long distance, and simultaneously, the contour of the paper pattern can be correctly reproduced.</p> |
