PURPOSE: To eliminate boarding work of printed paper and attain the automization and labor saving of printing work by using a belt board having belts capable of sliding on both surfaces of an air table to receive a falling printed paper.

CONSTITUTION: Two sets of belt boards 1, 10 consisting of belts capable of sliding laid to cover both surfaces of an air table, a guide rail 2 and pusher 16 for guiding the belt boards to a printed paper receiving position, a sucker 19 for fixing the surface side belt, and a lifting truck 22 for receiving the belt boards and moving them to another device are provided. The surface-side belt is partly fixed by the sucker 19, and the air table 1 or 10 is pushed to the printed paper receiving position at a proper timing, whereby the printed paper can be taken out every fixed number of sheets and transferred to another device without preventing the normal falling of printed papers.
