PURPOSE:To store sheets at a folded sheet storage part properly by providing a sheet excessive-tension prevention mechanism part provided with thin plate- shaped vanes between a printing part and the sheet storage part, and rotating the thin plate-shaped vane synchronously with the delivering motion of a sheet to hit the sheet to be stored at the sheet storage part. CONSTITUTION:A sheet excessive-tension prevention mechanism part is constituted so as to move synchronously with the sheet delivering motion of the sheet delivering mechanism and provided with a motor 2 which rotates synchronously with the motion of the sheet delivering mechanism, and thin plate-shaped vanes 5, 8 which rotate synchronouly with the motor 2. Besides, the thin plate-shaped vane 5 is sent from a printing part by the sheet delivering mechanism to come into intermittent contact with the reverse surface of sheet 13 which drops in itself due to its gravity, and the thin plate-shaped vane 8 is provided at a lower position than the thin plate-shaped vane 5 to come into intermittent contact with the surface of the paper 13 which has passed through the thin plate-shaped vane 5. Because the edge which comes into contact with the sheet 13 of the thin plate-shaped vanes 5, 8 is formed into a continuous circular arc, it comes into partial contact with the sheet 13 to hit the sheet 1 effectively.
