Patent ID: 8356813

Claim:
A paper feeder assembly for an image forming apparatus, the paper feeder assembly being configured to sandwich a sheet of paper between a roller and an opposing pressing member and to feed the sheet of paper by the roller being rotated, the paper feeder assembly comprising: a pressure variable member configured to vary pressurized contact force between the roller and the pressing member; wherein based on a mechanical linkage between the pressure variable member and a power supply switch provided in a main body of the image forming apparatus, the pressure variable member is configured to generate pressure between the roller and the pressing member to ensure pressurized contact between the roller and the pressing member when the power supply switch is turned on, wherein based on the mechanical linkage between the pressure variable member and the power supply switch provided in the main body of the image forming apparatus, the pressure variable member is configured to separate the roller and the pressing member from each other when the power supply switch is turned off, wherein the roller is configured to rotate about a first axis, wherein the pressing member is configured to rotate about a second axis, wherein the first and second axes define a segment of a first plane between the first and second axes, and wherein the pressure variable member is configured to rotate about a first fulcrum disposed in a second plane that perpendicularly intersects the segment of the first plane.
