<p>PURPOSE:To favorably realize stacking of discharged paper sheets in a simple constitution by supporting a tray through a pantograph mechanism in a device where the tray is provided in a movable manner in parallel in the vertical direction in a discharged paper sheets stacking device. CONSTITUTION:A discharged paper sheets stacking device A attached to a laser printer or the like is provided with a discharged paper sheets stacking device body 21 whose bottom surface 22 is inclined toward a printer body 10 by the angle alpha relative to the horizontal plane, and provided with a tray 23 on this inclined surface part 22a in a movable manner in parallel in the vertical direction through a pantograph mechanism 24. This tray 23 is also formed in the shape where the printer body 10 side is inclined similarly to the bottom surface 22. In the pantograph mechanism 24, a pair of levers 25, 26 which are crossed to each other in a rotatable manner at the fulcrum shaft 27 are arranged on both sides, and the respective ends of an energizing spring 30 whose intermediate part is supported by the fulcrum shaft 27 are engagingly locked to the lower side of the respective levers 25, 26 and the tray 23 is energized upward, and the tray 23 is lowered according to the weight of the paper sheets stack.</p> |
