ABSTRACT:
An apparatus for quickly and accurately aligning a layout to be duplicated having a copy board with an upper work surface for receiving a layout to be aligned and duplicated; an alignment pattern member including an alignment pattern; a wave energy projecting member positioned adjacent the upper work surface of the copy board for projecting an image of the alignment pattern onto the upper work surface; a duplicating member positioned adjacent the upper work surface of the copy board for duplicating the image of the layout; an orienting member for orienting the projected image of the alignment pattern with the duplicating member; and a cut off member for removing the projected image of the alignment pattern from the upper work surface of the copy board prior to the operation of the duplicating member.
