ABSTRACT:
A platen, supplemental feed rollers and a paper feed roller are driven by a motor, feeding a stack of sheet papers on a hopper one by one to the platen. When a predetermined period of time elapses after the sheet paper has reached a photosensor, the motor rotates in the reverse direction to reversely rotate the platen. The paper feed roller and the supplemental feed rollers however keep rotating to execute an oblique compensation of the paper. Then, an electromagnetic clutch is disengaged to permit the paper feed roller to freely rotate, feeding the paper to a print position by the rotation of the platen. When the power of a printer is turned off and an operational lever is moved to a paper releasing position, a switching lever oscillates, disengaging a planetary gear mechanism from other gears. This sets the supplemental feed roller free. Further, manipulating the operation lever presses down the support plate of the hopper to separate the paper from the paper feed roller, thus permitting removal of this paper.
