To provide a double-side printing apparatus capable of automatically applying printing to both upper and rear surfaces of printing paper.
Stencil paper is provided on the outer peripheral surface of a printing drum 3. A paper feed roller 21 supplies printing paper P to the printing drum 3. A press roller 26 presses the supplied printing paper P to the printing drum 3 to perform printing. The printed printing paper P is passed through a re-transfer preventing mechanism 28 to enter a belt type reversal means 30 by the changeover of a changeover means 35. The printing paper P is sucked and held to a belt by an air force holding means 32 and turned upside down by the driving of the belt to enter a primary paper discharge part 25. The primary paper discharge part 25 is raised to be set to the position of a paper feed stand 19. The printing paper P of which the rear surface is printed is again sent to the printing drum 3 by the paper feed roller 21 and the upper surface is also printed. The changeover means 35 is changed over and the printing paper is discharged to a secondary paper discharge part.
