This invention is related to a feeder for transporting a print medium from a tray along a U-shaped transporting path. The feeder comprises a movement member (50) coupled to a feeding roller (10). Themovement member (50) comprises a first portion (50b) located at a position such that the print medium makes contact with the first portion when a transporting roller (13) and the feeding roller (10) simultaneously make contact with the print medium. The first portion receives a force from the print medium when the first print medium makes contact with the first portion. The movement member (50) moves the feeding roller by utilizing the force such that a distance between the feeding roller (10) and the support surface of the tray increases.
