PROBLEM TO BE SOLVED: To more surely correct the attitude of a sheet having a long sheet length.SOLUTION: When a long sheet PL is conveyed, two rotary members provided in each of second conveyance rolls 45 are separated. When the long sheet PL is conveyed as shown in a code 5A, a tip PF of the long sheet PL is detected by a rear sensor Cr and a front sensor Cf, and skew amount of the long sheet PL is grasped on the basis of the detection result. After that, a rear side roll 46R and a front side roll 46F are controlled on the basis of the grasped skew amount so as to reduce inclination of the long sheet PL.SELECTED DRAWING: Figure 5 |
