Claims (1)

[Scope of Claim for Utility Model Registration] A paper storage section, a rising biasing member that urges the paper in the paper storage section to the rising side via the bottom plate, and a topmost paper that is lifted by the rising biasing member. A paper feed roller that rotates and presses against the paper to feed the paper, a pair of separation claws each having claws located at both corners of the feeding end of the paper, and at least one of which moves in the paper width direction perpendicular to the paper feeding direction. a pair of side fences, the separating claw is rotatable at least toward the moving side of the side fences so as to regulate the upper limit of the rise of the sheet lifted by the rise biasing member; At the same time, a locking portion is provided approximately directly below each claw portion of the pair of separation claws to protrude in the paper feeding direction, and the locking portion is received in the paper storage portion opposite to the locking portion. A paper feeding device characterized in that a separating claw upward regulating groove is formed at the same time to allow movement in the moving direction of the side fence.
