Abstract:
A paper feed unit comprising:a paper feed tray stacking sheets thereon; a primary paper feed roller; a secondary paper feed member provided downstream to the primary paper feed roller in a transferring direction of the sheets, an uppermost sheet among the sheets stacked on the paper feed tray being transferred toward the secondary paper feed member by rotation of the primary paper feed roller, the sheet being further transferred while a tip end of the sheet contacts with the secondary paper feed member, and primary paper feed being then completed while the sheet is being bent; a counter rotation stop mechanism allowing the primary paper feed roller to rotate in a paper feed direction but preventing the primary paper feed roller from rotating in a counter direction to the paper feed direction; and a rotation stop release mechanism releasing a state in which the primary paper feed roller is prevented from rotating in the counter direction by the counter rotation stop mechanism.
