PROBLEM TO BE SOLVED: To lower an upper end position of a gradient guide surface so as to make misalignment of distal end positions of multiple lithographic printing plates stacked on a stacking surface, and to prevent the distal ends of the printing plates from being inserted below a stopper member. SOLUTION: A limiting member 90 is interposed together with a cushioning material 72 between a support plate 62 and a protective sheet 74 at the stopper member 60 for limiting a movement of the lithographic printing plate 46 in a conveying direction F. The member 90 limits a flexible deformation of the sheet 74 at its lower side part from an upper end of the gradient guide surface 94 of the sheet 74 at the time of colliding with the plate 46 with the member 60. Thus, when the plate 46 is made to collid with the member 60, a part of the lower side from the upper end of the guide surface 94 of the sheet 74 is prevented from being locally excessively flexibly deformed by a load from the plate 46 and the distal end of the plate 46 is prevented from being inserted below the member 60. |
