A clamper clamps an edge of a lenticular sheet and moves in a sub-scanning direction to transport the lenticular sheet. While the lenticular sheet is transported so as to form an image receptor layer on a rear side of the lenticular sheet, a sensor unit is moved in a main-scanning direction, such that the sensor unit is moved relative to the lenticular sheet in a direction which has a predetermined measurement scanning angle from the main-scanning direction. The sensor unit receives an inspection light projected toward and passed through the lenticular sheet, and outputs a detection signal corresponding to a received amount of the inspection light. Based on a variation of the inspection light, an oblique transportation angle of the lenticular sheet is calculated and the clamper is rotated in a direction to cancel the oblique transportation angle of the lenticular sheet. |
