Abstract
A control apparatus insures precise reading or entry of data in the proper columns and rows or lines of chart sheets mounted atop a board. The same columns with appropriate indicia appear on both the top of the chart sheets and on a vertically shiftable ruler member attached to the board. A slide block associated with the ruler member not only maintains the ruler in a positive horizontal disposition parallel to the chart sheet rows but automatically adjusts in height to accommodate a varied amount of chart sheets on the board.
