ABSTRACT:
Disclosed herein is a light source unit for emitting multiple beams, which can be reduced in size. The light source unit (10) is formed by a base block (5) and ten stays (3). Ten locating pins (6) are provided on each side of the base block (5) at a second space (d) in a direction Y' and a third space (l) in a direction X'. Eight holes (7) are provided in each stay (3) at a first space (D), while holes (8) for locating pins (6) are provided on both ends thereof. A semiconductor laser is arranged in each hole (7). Each of the locating pins (6) is inserted into one individual one of the pin holes (8) and the ten stays (3) are then fixed to the base block (5) by through bolts (17). Thus, eight times ten semiconductor lasers are arranged on a two-dimensional plane of X'-Y' coordinates.
