PURPOSE:To realize the detection for both the regions and their corresponding relations, by writing the inserting and sampling regions in different colors along with the use of the paper by which the corresponding regions can be connected with a segment of a line and reading each region by means of a double-color reader. CONSTITUTION:The output of a double-color reader 21 is supplied to the 4th storage device 8 which stores a binary electric signal (a) as well as to another 4th storage device 22 which stores a binary electric signal (b). A type-based mark detector 2 detects the type-based mark out of the output of the device 8. The 1st and 2nd detectors 3 and 23 detect the black and red closed curves to detect both the sampling and inserting regions and store the information on the size, position and shape, etc. into the device 4. Then the segments of lines connecting the regions detected by the detectors 3 and 23 are detected. The information on each region and the corresponding relations of the regions are recognized based on the results of the 3rd detector 24 plus the detectors 3 and 23 which are supplied to the 2nd storage device 6. Thus a correspondence table is produced. |
