<p>PROBLEM TO BE SOLVED: To discharge even a sheet having a low stiffness without buckling. SOLUTION: Upper guides 40-1 to 40-5 and lower folding guides 43-1 to 43-5 are laid on sides of a pair of discharge rolls 25-1. The upper guides 40-1 to 40-5 are fixed at positions. The lower guides 43-1 to 43-2 are rotatable around a rotary shaft (which is not shown) as a center. A sheet S1 having a width less than a predetermined size, is discharged by the pair of discharge rollers 25-1, and side parts of the sheet are guided by the upper guides 40-1, 40-2 and the lower guides 43-1, 43-2, and so as to be bent upward (refer to Figure (a)). Further, when a sheet S2 having a width larger than the predetermined size is discharged by the discharge rollers 25-1, side parts of the sheet are guided by the upper guides 40-3, 40-4, 40-5 and the lower guides 43-4, 43-5 so as to be bent upward.</p> |
