Patent ID: 7628394

Claim:
A feeder for transporting a print medium from a tray along a U-shaped transporting path, comprising: a tray comprising a support surface upon which a print medium is to be placed; a feeding roller located at a position facing the support surface of the tray, wherein the feeding roller feeds the print medium toward the U-shaped transporting path; a transportation guide forming the U-shaped transporting path; a transporting roller located at a position adjacent to a downstream end of the U-shaped transporting path, wherein the transporting roller and the feeding roller have a positional relationship that allows the transporting roller and the feeding roller to simultaneously make contact with the print medium; a controller that controls the transporting roller and the feeding roller such that a tension is generated in the print medium when the transporting roller and the feeding roller simultaneously make contact with the print medium; and a movement member coupled to the feeding roller, wherein the movement member comprises a first portion and a second portion, the first portion is configured to be located at a position where the print medium makes contact with the first portion when the transporting roller and the feeding roller simultaneously make contact with the print medium, the first portion receives a force from the print medium when the print medium makes contact with the first portion, the second portion is configured to be located at a position where the second portion pushes the print medium being transported from the tray, and the movement member moves the feeding roller by utilizing the force such that a distance between the feeding roller and the support surface of the tray increases.
