A paper feeding device comprising a tray storing case (3) attachable to and removable from a device housing (2); a rotatable tray (4), provided in the tray storing case (3), which rotates copy paper (44) to a longitudinal and lateral feed position; and a mechanism for lifting up a paper-feed end of a paper holding plate (25) provided in the tray when paper is to be fed. The mechanism is composed of a guide member (17) provided in the device housing (2); a lift-up guide (55,56) provided on a side face located on a paper-feed end of the tray; a first rotary bar (40) provided in the tray storing case (3) and driven by the guide member (17) when the tray (4) is attached thereon; and a second rotary bar (41), a spring (54) and a lift plate (26) driven by the lift-up guide (55,56) when the tray is in the paper-feed position. The first and second bars (40,41) are driven simultaneously, thus lifting up the paper-feed end of the paper holding plate (25). Alternatively, the mechanism comprises at least three springs (63-65) provided between the tray and the tray storing case; a guide rib (85,86) provided in the tray storing case; and a pivot pin (61), a wire (78) and a slide plate (68,74) provided on the paper holding plate. The guide rib causes the slide plate to rotate and the wire pulls the pivot pin downwards. A simplified and miniaturized mechanism that lifts up and lowers the paper holding plate (25) is thus achieved. <IMAGE> |
