Abstract:
1. A printer, comprising: a sheet supply unit that accommodates a stack of sheets therein; a pickup roller which contacts and drives one side of the stack of sheets accommodated in the sheet supply unit and thereby feeds each sheet toward a printing unit; a cover which covers the other side of the stack of sheets accommodated in the sheet supply unit; and a forcible curling unit which forcibly curls the sheets accommodated in the sheet supply unit in a sheet width direction, wherein the forcible curling unit reduces curling of the sheets during feeding in a sheet feed direction that is substantially perpendicular to the sheet width direction, wherein the forcible curling unit includes a rib which is provided inside the sheet supply unit to protrude toward the cover so that a tip of the rib will press the stack of sheets accommodated in the sheet supply unit at its central part in regard to the sheet width direction, and wherein the cover is provided with a pressure plate which applies pressure on the sheets accommodated in the sheet supply unit toward the pickup roller, the pressure plate being separate from, and attached to the cover in such a manner as to cause the sheets to curl in the sheet width direction, the pressure plate having a width that is substantially same as a width of the sheets.
