Abstract:
A device for positioning a sheet member, the device comprising:a generally flat plate on which the sheet member is received; a conveying device provided so as to correspond to the sheet member received on the plate, and conveying the sheet member in one direction; a temporary abutment member provided at a side of the plate in the one direction, and due to the sheet member, being conveyed in the one direction, the sheet member abutting the temporary abutment member at at least two points, which determines a position of the sheet member in a temporary direction; an actual abutment member provided at said side of the plate, and due to the sheet member being conveyed in the one direction after the position in the temporary direction has been determined, the sheet member abutting the actual abutment member at at least two points, which determines a position of the sheet member in an actual direction; a conveying force applying device applying a conveying force to the sheet member in another direction substantially orthogonal to the one direction, to the sheet member; and a reference abutment member provided at another side of the plate in that another direction, and due to the conveying force in said another direction being applied to the sheet member, the sheet member abutting the reference abutment member, which determines a position of the sheet member in said another direction, wherein an angle of inclination of the temporary direction with respect to the one direction is &agr;, and an angle of inclination of the actual direction with respect to the one direction is &bgr;, &agr;
