Abstract: A sheet feeding roller (101) which feeds a sheet S stacked on a sheet supporting plate (110) capable of being lifted and lowered is swingably supported at a swing end of a sheet feeding roller supporting arm (104) which is arranged swingablyin an up-and-down direction and a roller biasing member (103) applies a force to the sheet feeding roller supporting arm (104) in a direction that the sheet feeding roller (101) is pressed to sheets S stacked on a sheet stack tray (61). A swing fulcrum (104a) is arranged in arange between a tangential line of the sheet feeding roller (101) at the upstreammost pressing position against the sheet feeding direction and a tangential line of the sheet feeding roller (101) at the downstreammost pressing position out of pressing positions where the sheet feeding roller (101) is pressed to the sheets as being varied inaccordance with a sheet stacking state of the sheets.

Abstract: A sheet feeding roller (101) which feeds a sheet stacked on a sheet supporting plate (110) capable of being lifted and lowered is supported by a support portion (71a) as being linearly movable in an up-and-down direction, and a roller biasing member (103) applies a force to the support portion (71a) in a direction in which the sheet feeding roller (101) is pressed to a sheet stacked on the sheet supporting plate (110). A biasing direction (101b) of the sheet feeding roller (101) due to the roller biasing member (103) is set within a range between a normal line of the sheet feeding roller (101) at the upstreammost pressing position against the sheet feeding direction and a normal line of the sheet feeding roller (101) at the downstreammost pressing position out of the pressing positions where the sheet feeding roller (101) is pressed to the sheet as being varied in accordance with a sheet stacking state of the sheets.

Abstract translation: 供给堆叠在能够升降的片材支承板（110）上的片材的片材进给辊（101）由能够沿上下方向直线移动的支撑部（71a）支撑， 辊偏压构件（103）沿着将片材进给辊（101）按压到堆叠在片材支撑板（110）上的片材的方向向支撑部分（71a）施加力。 由于辊偏压部件（103），供纸辊101的偏置方向101b被设定在上游侧压纸位置的送纸辊101的法线与送纸方向 以及在片材进给辊（101）被按压到片材的按压位置之外的最下压位置处的片材进给辊（101）的正常线根据片材的片材堆叠状态而变化。
