    摘要： A feeding device includes a paper feed tray, a detector on an image forming apparatus main body, a control member rotatably supported by the paper feed tray, and spacers. The detector includes movable pieces and contact points corresponding to the movable piece, and switches each contact point by the position of the corresponding movable piece. The control member includes a control surface formed on its outer circumferential surface with projecting and recessed portions. The projecting and recessed portions are disposed in a pattern corresponding to rotation angles in an area of the control surface facing the movable pieces. Controlling the positions of the movable pieces according to the pattern encodes paper size. Each movable piece is lined in the circumferential direction facing the control surface. The outer circumferential surface of the projecting portions is formed in a cylindrical surface shape centering around the rotational axis of the control member.

    摘要： A feeding device includes a receptacle, a conveyor, an elastic member, and a load adjuster. The receptacle is vertically movable and holds a stack of sheets. The conveyor feeds an uppermost sheet of the stack of sheets on the receptacle in a feeding direction in which a sheet of the stack of sheets is fed. The elastic member biases the receptacle to press the uppermost sheet of the stack of sheets on the receptacle against the conveyor. At least when a height of the stack of sheets on the receptacle is equal to or greater than a given value, the load adjuster applies a reduced magnitude of load downward to the stack of sheets on the receptacle in response to a decrease in the height of the stack of sheets.
