PROBLEM TO BE SOLVED: To omit a development processing of a photosensitive material and to shorten a time required for adjusting a press-fitting force of a press-fitting roller by tracing a line along a front surface or a back surface of the photo-sensitive material by a pen plotter while the photo-sensitive material is conveyed by a roller mechanism comprising a driving roller and the press-fitting roller. SOLUTION: A pen support member 66 is mounted to a second guide part 25 provided between first and second press-fitting rollers 21, 23 by two screws 67 and a pen 65 is mounted to the support member 66 by a mounting member 68. A tip end of the pen 65 is inserted to a hole part 25a formed on a second guide member 25. When a paper is conveyed from a lower position to an upper direction, in the case where a press-fitting force is appropriate, a pen track is traced on a center portion at a straight line since the paper is normally conveyed. In the case where the press-fitting force is not appropriate, a pen track is traced in a meander state. The press-fitting force of the first press- fitting roller 21 and the second press-fitting roller 23 is separately and independently adjusted by rotating an adjusting screw such that the pen track becomes a straight line.
