Abstract
A low profile opto-device panel assembly suitable for use in an input detection apparatus used as an input device in conjunction with a visual display is disclosed. Arrays of light emitting devices and light detecting devices are juxtaposed along the internal edge of a peripheral frame printed circuit board to reduce the overall height of the panel assembly. Alignment housings surrounding each of the arrays of opto-devices are attached to the printed circuit board and extend inwardly of the sides of the peripheral frame printed circuit board. The opto-devices disposed in the alignment housings along the internal edge of the printed circuit boards are mechanically and electrically interconnected to the printed circuit board by bent leads which extend along the upper surface of the printed circuit board and into conventional printed circuit board holes.
