PROBLEM TO BE SOLVED: To solve a problem of notable difficulty in printing on both sides without worrying about smudging in a delivery blow-up device for a conventional sheet-fed printer using a paper guide bar. SOLUTION: This delivery blow-up device for the sheet-fed printer is constituted to lift printing paper in the air by setting a paper guide plate under the printing paper, setting an air nozzle thereunder, and blowing up air between the printing paper and the paper guide plate so that the printing paper gripped by a chain gripper does not hang down.
