A printed circuit board coordinate reader may be used to read coordinates on different types of cards with different coordinate schemes. A transparent framelike fixture contains slots along one side and along the bottom to receive scales for the X and Y directions. A pair of transparent reader guides, each provided with a hairline, ride respectively in the horizontal and vertical directions until the intersection of the hairline coincides with the component lead in question. The coordinate position of the lead is then read from the scales at the side and bottom of the fixture. As shown in the figure, the reader includes a transparent frame- like fixture 10 which provides a rectangular opening 12 intended to overlie the circuit board whose coordinates are to be read.
