Claims

[Scope of Claim for Utility Model Registration] In a printing device that performs printing while feeding printing paper P from a paper supply side to a paper discharge side via printing units 2 and 6, the paper supply side of the printing units 2 and 6 and Paper feeding means 8, 9 for feeding the printing paper P on the paper discharge side; and paper feeding rollers 12A, 12B for bringing the printing paper P into contact with the paper feeding means 8 on the paper supply side.
and a discharge roller 15 which is arranged so as to be able to come into contact with and separate from the paper feed means 9 on the paper discharge side, and which brings the printing paper P into contact with the paper feed means 9 when the discharge roller 15 comes into contact with the paper feed means 9; a moving means 14 that moves toward and away from the means 9; a signal generating means 13 that generates a predetermined signal before the printing paper P leaves the paper feed rollers 12A and 12B as the printing paper P is fed; 17, based on the signals from the signal generating means 13, 17, actuating the moving means 14 to move the discharge roller 15;
a control means 17 for bringing the paper into contact with the paper feeding means 9.
