Title: Sheet processing unit

Abstract: A taking part has a taking unit that comes in contact with the piled sheets to generate a taking force and to take the sheets one by one with the taking force. A movable lever is arranged in a side of the taking unit with respect to the piled sheets, and a driving unit gives a driving force in a linear or rotational direction to the movable lever. A force controller controls the driving force given to the movable lever by the driving unit. A detecting unit detects a position of the movable lever, and a sheet supplying unit supplies the piled sheets to the taking unit. A sheet supplying unit controller controls the sheets supplying unit on the basis of the position of the movable lever detected by the detecting unit. The sheets are pressed by the lever at a preparatory step, and then the sheets are lifted and pressed to the taking unit while canceling the driving force by the lever. The sheet and the taking unit are assured to become in good contact with each other to make the taking operation stable.
