PURPOSE: To make the paging order of paper discharged correctly arrangeable at the time of automatic printing of continuous documents in bulk by forming a paper discharge tray into a movable system, and making a paper discharge direction free of changing over to both nearby and remote sides to an operator.

CONSTITUTION: When a paper discharge tray 10 is tilted to the side remote to an operator, paper 4 is discharged in a state of being upped of its face. Consequently, printing can be done as making certain of a printing state. In addition, when the tray 10 is tilted to the nearby side of the operator, the paper 4 is discharged in its face down state. Accordingly, the paper 4 is stacked aright at paging order.
