Abstract
A printing medium feeding device includes: a driving roller having a roller circumferential surface coming in contact with a printing medium to apply a feeding force to the printing medium around a core line of a rotation shaft and rotating to feeding the printing medium downstream; a driven roller in contact with the driving roller and following the rotation thereof; a shaft supporting member supporting the rotation shaft at least at two supporting positions; and a regulation unit regulating a core position of the rotation shaft between the two supporting positions at which the rotation shaft is supported by the shaft supporting member, wherein the regulation unit has a pressing surface coming in contact with the rotation shaft from the upstream side or the downstream side of the rotation shaft, and wherein the core position of the rotation shaft at the position of the regulation unit is located by the pressing surface to be more downstream than a straight line passing through the core positions of the rotation shaft at the two supporting positions when the pressing surface comes in contact with the rotation shaft from the upstream side, and the core position of the rotation shaft at the position of the regulation unit is located to be more upstream than the straight line when the pressing surface comes in contact with the rotation shaft from the downstream side.
