ABSTRACT:
The present invention discloses an apparatus disposed in a printer for turning over printed papers, which is capable of guiding printed papers to move toward a first paper receiving tray or a second paper receiving tray so as to pile the printed papers thereon with face down or face up. The apparatus includes a shaft disposed within the printer which is capable of being pivotally rotated around its longitudinal axis; a guiding means fixed on the shaft, having a first guide surface for guiding printed papers to move toward the first paper receiving tray and a second guide surface for guiding printed papers to move toward the second paper receiving tray, the first and second guide surfaces are disposed in such a way that only one of the first and second guide surfaces, in one time, is guided to face printed papers when the shaft is pivotally rotated around its longitudinal axis; and a crank capable of being urged by the first paper receiving tray. The gravitation center of the guiding device and the shaft are eccentric to the longitudinal axis of the shaft, so that the gravitational force of the guiding device and the shaft always drive the shaft to rotate to a first attitude that the first guide surface faces printed papers to guide the printed papers to move toward the first paper receiving tray, and the crank will guide the shaft to rotate to a second attitude that the second guide surface faces printed papers to guide the printed papers to move toward the second paper receiving tray when the first paper receiving tray urges the crank.
