Claims

[Scope of utility model registration request]

The side fence is attached to the bottom of the cassette so that its position can be adjusted perpendicular to the paper feeding direction and guides both sides of the paper during paper feeding, and the front end of the side fence rotates in a vertical plane parallel to the side fence guide surface. an arm whose one end is freely pivoted; the arm has a horizontal protrusion at its free end that projects horizontally inward when the arm extends forward and is positioned horizontally; and a horizontal protrusion that is parallel to the side fence guide surface. In the paper feeding cassette, the vertical protruding part of the arm has a lower inclined surface on the inner surface of the vertical protruding part, the lower edge of which reaches at least the guide surface of the side fence, and the upper edge of the vertical protruding part of the arm. A paper feed cassette characterized in that a flat plate which is in contact with the lower surface of the horizontally projecting part and substantially parallel to the side fence guide surface is elastically supported so that the distance between the flat plate and the inner surface of the vertically projecting part can be expanded and contracted.
