Abstract
A plurality of image arrays are sandwiched between a first and a second substrates. The common electrodes of the image arrays are connected to the first substrate; the individual electrodes of the image arrays are connected to the second substrate by flip chip connection. The image arrays are installed in holes of a spacer made by etching a metal plate. Plural lenses are installed in a lens plate made by etching a metal plate; the lens plate is secured to support members for positioning the lenses with respect to the image arrays. The image arrays include a plurality of light elements which may be either light emitter or light receiver elements.
