JPS5620382A - Information input system using facsimile transmitter - Google Patents

Abstract

PURPOSE:To shorten the time of processing and to reduce memory capacity by correcting the position and gradient of a form by providing a simple rule for entering picture information and number-mark information in the form and then inputting data to a processor by recognizing numbers and marks. CONSTITUTION:On input form 1, reference position mark 2, gradient detection marks 3 and 4 and other several kinds of assignment marks are provided. Then when form 1 tilts down to the right, the scanning signal of facsimile transmitter 71 is received by interface circuit 72, which outputs picture signal P of every line. Position correcting circuit 73 detects mark 2 from picture signal P and outputs effective picture signals Pe following mark 2. Receiving signal Pe, tilt-angle calculating circuit 74 detects marks 3 and 4 to detect form 1 tilting down and right to the main scanning direction of transmitter 71 by a few lines and then sends an indication of a method needed for inclination correction to inclination correction circuit 75. Then, effective picture signals Pr having the inclination corrected by circuit 75 are generated successively and output to information area detecting dircuit 76, thereby inputting normal picture signals to processor 81 by way of interface circuit 80.
