An image reading device including an image reading unit, a pick roller, and a single feed roller. A projection is provided on the roller shaft, and a pawl is provided in the pick roller, so that the projection can engage with the pawl to transmit the rotation of the roller shaft to the pick roller, and the projection can disengage from the pawl to allow the pick roller to freely rotate relative to the roller shaft. In a further aspect, a sheet separating pad assembly comprises a pad mount member pivotally attached to the frame by a pivot shaft, a sheet separating pad supported by the pad mount member, a backing pad swingably attached to the pad mount member by a backing pad shaft, and a spring arranged below the backing pad shaft to urge the backing pad to thereby urge the sheet separating pad to the pick roller.
