Abstract
A plate positioning apparatus which determines the position of a plate workpiece for a processing machine by an aligning member which moves in the X-axis direction and an aligning member which moves in the Y-axis direction. The Y-axis aligning member is provided with a movable retainer which retracts toward the Y-axis side when it comes in contact with the X-axis side aligning member and comprises a base part and an extension member which is remountable on the base part. The aligning member for the X-axis is provided on its upper surface with at least one aligning bar which contacts the plate workpiece. The aligning members for both directions of X and Y axes are adapted to be guided by the base frame and their moving strokes are controlled by position detecting switches provided in the base frame, the base frame being closed at its upper side by the cover plate. The respective slits along which the aligning members move are covered with respective movable dust-proof belts.
