ABSTRACT:
A hand scanner input system has a hand scanner. The scanner scans a medium having an image or images such as characters or graphic patterns. A mark is printed on this medium or on a transparent sheet to be placed on the medium. Hence, the mark is read when the scanner scans the medium. The image and mark read by the scanner are input to a data processor having a microcomputer. The microcomputer eliminates overlapping of the pieces of image data read by the scanner and the displacement of the scanning start position in accordance with the data representing the mark.
