Abstract:
1. A sheet alignment and ejection mechanism for use in an office machine, said sheet alignment and ejection mechanism comprising: a sheet alignment device comprising at least one paddle, a first one-way element and a first rotation shaft, wherein said first one-way element comprises an alignment gear, said first one-way element is sheathed around said first rotation shaft, and said paddle is attached on said first rotation shaft, wherein when said first one-way element is rotated in a first direction, said first rotation shaft and said paddle are driven by said first one-way element to be rotated in said first direction, wherein when said first one-way element is rotated in a second direction, said first rotation shaft and said paddle are immobile; a sheet ejection device comprising at least one sheet ejection assembly, a second one-way element and a second rotation shaft, wherein said second one-way element comprises a sheet ejection gear, and said second one-way element is sheathed around said second rotation shaft, wherein when said second one-way element is rotated in said first direction, said second rotation shaft and said sheet ejection gear are driven by said second one-way element to be rotated in said first direction, wherein when said second one-way element is rotated in said second direction, said second rotation shaft and said sheet ejection gear are immobile; a power device comprising a driving gear, wherein said driving gear is driven by said power device to be rotated in either said first direction or said second direction; and a transmission unit comprising plural gears, wherein said plural gears are connected with said power device, said first one-way element and said second one-way element for driving rotation of said first one-way element and said second one-way element, wherein said first one-way element and said second one-way element are rotated in opposite directions.
