PROBLEM TO BE SOLVED: To prevent collision between a rear end of an odd-numbered printing sheet and a tip of an even-numbered printing sheet to be discharged when a stencil printer performs printing in a double-speed printing mode.SOLUTION: Before a first printing sheet 4-1 passes through the position of a sheet discharge sensor 47 to get on a guide plate 63, the sheet introduction side in the guide plate 63 is oscillated downward. The guide plate 63 guides the printing sheet 4-1 in the obliquely upward direction to abut on an end fence 62. While the printing sheet 4-1 collides with the end fence 62, a second printing sheet 4-2 is discharged to the guide plate 63, but collision between the rear end of the printing sheet 4-1 and the tip of the printing sheet 4-2 can be avoided since the rear end of the printing sheet 4-1 is lowered.SELECTED DRAWING: Figure 3 |
