<p>PURPOSE:To input required data information to a memory unit accurately and precisely by eliminating the need or additional facilities by photoelectrically scanning a pattern with the displayed data information by a photoengraving color scanner itself. CONSTITUTION:While pattern 1 where data information is graphed in a curve is rotated being wound around original-picture drum 2, pickup head 3 is moved in the axis-line direction of drum 2 for a sequential photoelectric scan. Pattern 1 consists of origin support line 6, reference coordinate axis line 7 and required data curve 8 of (t1), (t2) and (t3) in single scan time required in the main sdan (Y axis) direction, and pulse-width detectors 9, 10 and 11 detect lines 6, 7 and 8 respectively according to the rotation of drum 2. After (t1), counter 12 counts up by ''1'' at every time when head 3 passes through line 7, and counter 12 counts clock pulses while head 3 is between line 7 and line 8, so that an address value and input data value will be sent to the memory unit at that point in time.</p> |
