  • Patent number: 9026031
    Abstract: The bottom surface of a paper cassette that supports recording paper is configured of a first bottom surface and a second bottom surface. The second bottom surface is formed of a swing member having a fulcrum at the downstream side in the paper feeding direction and being capable of swinging about the fulcrum with the upstream side in the paper feeding direction serving as a free end, thereby providing a structure in which an angle formed by the second bottom surface and a separation slope increases when the second bottom surface is caused to sink downward by a swing of the swing member.

  • Patent number: 8616667
    Abstract: In a feeding course, a first design side end position Xsn of a paper is calculated. A first side end position of the paper is detected by a paper width detector, and the detected position is set to a first side end position Xd1. When the paper is fed from an additional cassette and a paper end detection flag F1=1, an ejection starting position adjustment amount ?X=Xd1?Xsn is set. However, when the deviation amount is not |Xd1?Xsn|?L, the ejection starting position adjustment amount ?X is limited to a limit value L.
