PURPOSE: To carry out paper feed smoothly, and clean an acute rotator simply by providing a covering member for covering the acute rotator in a manner that a partially circumferential surface apart from the paper eject roller of the acute rotator projects from the cut-out part.

CONSTITUTION: Paper printed at a printing part C and fed to an eject roller 11 is pressed down on the eject roller 11 by means of a spur (an acute rotator) 12, and ejected then from the roller 11 to a paper receptalce 19. Since the spur 12 is not brought into press contact with a rotational resistor such as a plotter roller, no excessive rotational loads operate thereto, so that the printed paper can be forwarded urgedly smoothly by the spur 12 and eject roller 11. As required, while the spur 12 is rotated appropriately, the upper circumferential surface 12u of the spur 12 can be cleaned, which projects from the cut-out hole 13a of a spur holder (covering member) 13. In this instance, cleaning work can be done safely, because the spur 12 is exposed only in its upper circumferential surface 12u.
