ABSTRACT:
A printer is provided in which even if short sheets are fed therethrough, these sheets are properly fed and are prevented from twisting during a sheet feed operation. Thus a paper jam caused by a defective sheet feed operation can be prevented. The printer includes sheet feed rollers, a hopper that is retractable with respect to the sheet feed rollers 21, the hopper urging a sheet to be printed upon toward the sheet feed rollers 21, and a link that insures the hopper moves in parallel with the sheet feed rollers when retracted, and when even short sheets are placed within the hopper.
