Claims (1)
より順次送り出す給送手段と、直流モータを備え
た駆動装置と駆動連結され、前記シート積載部を
待機位置から給紙位置へ押上げる押上げアームと
、前記給送手段に接する使用位置と該使用位置か
ら退避した退避位置との間で移動可能な手差し台
とを有する給紙装置において、前記手差し台が退
避位置から離れたことを検知する検知手段を設け
、シート積載部が給紙位置にある際、検知手段の
信号により前記直流モータをシート積載部が給紙
位置から待機位置へ戻る方向へ回転駆動すること
を特徴とする前記給紙装置。 a feeding unit that sequentially feeds out the sheets stacked on the sheet stacking unit starting from the topmost sheet; a push-up arm that is drivingly connected to a drive device including a DC motor and pushes up the sheet stacking unit from a standby position to a paper feeding position; In a paper feeding device having a manual feed table movable between a use position in contact with the feeding means and a retracted position retracted from the use position, a detection means for detecting that the manual feed table has left the retracted position. The paper feeding device is further characterized in that when the sheet stacking unit is at the paper feeding position, the DC motor is rotationally driven in a direction in which the sheet stacking unit returns from the paper feeding position to the standby position based on a signal from the detection means.
