摘要： A printer has a paper feed mechanism that can reliably balance the paper feed force of the paper feed roller and paper pressure roller on the left and right sides of the recording paper width. Using the self-centering action of a pressure lever fulcrum and adjustment of the position where an extension spring applies force, the paper feed mechanism of a printer can press the paper pressure roller that is supported by a pressure lever to a paper feed roller so that the paper pressure roller applies equal pressure at all points along the width of the paper feed roller, can balance the paper feed force applied by the paper feed roller and the paper pressure roller to the recording paper left and right widthwise to the paper, and can prevent the recording paper from meandering, skewing, and jamming.

摘要： A sheet feeding device includes a holding unit configured to hold a stack of sheets; a pickup roller, which feeds a sheet placed on top of the stack held in the holding unit when the pickup roller comes in contact with the sheet; a holder arm having a distal end to which the pickup roller is attached, wherein the holder arm has a swing center set at a position closer to the pickup roller side than the holding unit, and wherein the distal end of the holder arm extends from the swing center to the holding unit side; and a resiliently-deformable unit, which generates a swing moment to swing the holder arm to increases contact surface pressure between the sheet held in the holding unit and the pickup roller, wherein the swing moment increases as a contact angle between an extension direction of the holder arm and the sheet increases.

摘要： A printing medium supply device and an image forming apparatus having the same are provided. The printing medium supply device may include a pickup unit and an adjustment unit. The pickup unit may include a shaft, a pickup roller spaced apart from the shaft to come into contact with printing media, a pickup holder to support the pickup roller, the pickup holder being rotated about the shaft to lift or lower the pickup roller, and a link member connected to the pickup holder so as to be rotated about the shaft. The adjustment unit may include a pressure member coming into contact with a pressure applied portion of the link member to rotate the link member by applying pressure thereto, and an elastic member elastically supported by the pressure member to transmit elastic force to the link member. This configuration ensures constant pickup pressure despite variation in the quantity of printing media.
