摘要：A mechanically operated, gravity-assisted display device has the capability of being remotely controlled by an unskilled operator to display current numeric pricing indicia for a product or other alpha-numeric indicia for any required purpose. The device is ideally suited for displaying the unit price of gasoline on an elevated sign at a filling station. Multiple gravity-biased sliding panels which are arrayed to form variable indicia are operated remotely by flexible suspension elements equipped individually with fixed enlargements. Interchangeable coded remote operating cards for groups of the flexible suspension elements have passages through which predetermined enlargements may pass while other enlargements are blocked. Movement of the block enlargements with the flexible suspension elements to which they are attached under influence of the coded cards establishes the required change of displayed indicia. The coded cards are engaged in movable card holders which are shiftable between active and inactive positions in the housing of the controller.
