Abstract
A paper feed unit has a paper feed tray stacking sheets thereon, a primary paper feed roller and a secondary paper feed member, wherein an uppermost sheet among the sheets stacked on the paper feed tray is transferred toward the secondary paper feed member from the primary paper feed roller, a tip end of the sheet then contacts with the secondary paper feed member, and primary paper feed is then completed while the sheet is being bent. A counter rotation stop mechanism, which allows the primary paper feed roller to rotate in a paper feed direction but prevents the primary paper feed roller from rotating in a counter direction to the paper feed direction, and a rotation stop release mechanism, which releases a state in which the primary paper feed roller is prevented from rotating in the counter direction by the counter rotation stop mechanism, are also provided.
