Abstract: PURPOSE:To exactly collate the printed-out result with a reference pattern without loading any burden to a tester by picking up the images of the reference pattern and a pattern to be tested with plural video cameras and optically overlapping the picked-up images in different colors. CONSTITUTION:A reference pattern 2 printed on paper and a pattern 3 to be tested are respectively photographed by two white-and-black video cameras 1, and the respective patterns are plotted through a video amplifier 4 onto another CRT 5 in different colors.

Abstract: PURPOSE:To certainly correct the interval and the inclined advance of form- sheets by arranging a linear stepping motor in the transportation passage for form sheets and arranging a rotor equipped with a solenoid and allowing a gate installed onto the solenoid to move in reciprocation at a constant speed. CONSTITUTION:Form sheets are transported towards between a pinch roll 3 and a resist roll 4 by the weak nip force formed between a slip roll 1 and a driving roll 2. In this case, a rotor 7 which moves in reciprocation on a linear stepping motor 5 shifts in the state where the gate 8 of a solenoid 6 projects into a form- sheet transportation passage towards the resist roll 4 from a home position 9. The form-sheet is allowed to reach the gate 8 before the gate 8 reaches the resist roll 4, and the transportation speed of the form-sheet is restricted. Therefore, the interval between the succeeding sheet for the preceding sheet can be corrected to a constant value, and the inclined advance state is corrected.
