ABSTRACT:
An optical unit array comprises a plurality of optical units (2) in each of which a plurality of light source modules (1) are arranged and a first comb-teeth member (41) and a second comb-teeth member (42) which are provided for holding the optical units (2), and respective first pins (213) and second pins (214) of a plurality of optical units (2) are held by the first comb-teeth member (41) and the second comb-teeth member (42). In the optical unit array (4), positions of a plurality of optical units (2) relative to one another can be determined with high accuracy by bringing the first pins (213) and the second pins (214) into contact with grooves (411) and grooves (421), respectively. The outgoing positions and directions of light beams emitted from the light source modules (1) are also determined with high accuracy in each optical unit (2).
