PROBLEM TO BE SOLVED: To provide a conveyance device of a sheet matter capable of performing accurate conveyance in reverse conveyance with respect to different sheet materials.SOLUTION: A conveyance device for first and second sheet materials includes: an upstream roller which feeds the sheet material from a storage place; a driven roller of the upstream roller which is movable in a width direction; a guide device which regulates a width-directional position on the downstream side of the upstream roller; a downstream roller which feeds the sheet material to a processing position on the downstream side of the guide device; and a roll rotating unit which returns the second sheet material to a storage place on the upstream side of the upstream roller. In the reverse conveyance, the driven roller is moved to a position shifted from the width-directional center, the upstream roller is driven in the case of the first sheet material, the roll rotation unit is driven in the case of the second sheet material, and the driven roller is moved so that the shifted positions in the cases of the first sheet material and second sheet materials are located in opposite directions across the center. |
