PURPOSE:To facilitate alignment when setting papers by aligning the distance between anti-tilt board with the paper width on the basis of the differential potential of distance detection signal between each tractor and the anti-tilt board when regulating the paper width while moving one tractor manually. CONSTITUTION:When setting papers 3 in an unit, tractors 4-2 are moved manu ally while matching with the width of paper 3 to produce a voltage proportional to the differential voltage between the slide terminals 9, 15 through a differential amplifier 16 thus to drive D.C. motor 13. Consequently, a pinion 12 will rotate to move the anti-paper tilt boards 5-2 in the direction for eliminating the differen tial voltage through a rack 11. As a result, said boards 5-2 will move automati cally upon motion of tractors 4-2, thus to equalize the distance against the fixed tractors 6-2 and the anti-paper tilt boards 10-2. |
