Abstract: A photo receiving device includes four side rails with four corner members joining the side rails to form a rectangular frame, each of the side rails having a dove-tailed groove defined therein in which a plurality of pressing members and a hanger are movably and rotatably received. Each of the pressing members and the hanger has an ellipse shank which is sized to be movably received in or securely engaged with the dove-tailed groove by rotation. Each of the side rails has a flange extending from an inner side thereof so as to support a board mounted thereto which is pressed by the pressing members.
