PURPOSE: To prevent the occurrence of defective folding when the paper having a narrow printing paper width is cooled by providing at least one opening hole guiding part of the cooling wind to the below of a paper mount base on the printing paper stacking face of the paper mount base. CONSTITUTION: Multiple opening holes 9 are provided in the paper width direction L2 on the stacking face of a paper mount base 7. The wind F from a cooling fan 8 is diffused against the blowing direction, the wind F1 from the cooling fan 8 is sprayed from the side face of the width direction of the printing paper 2a to cool it, the wind F2 is sprayed in the direction to float the printing paper 2a, and it is guided to below the paper mount base 7 from the opening holes 9 to prevent the floating action. The quantity of the wind F applied to the end section of the printing paper 2a is adjusted to hardly float it, and a folding problem is reduced. The wind F2 guided to below the paper mount base 7 forms a one-way air flow below the paper mount base 7 to cool the printing paper 2a from its lower section through the opening holes 9. |
