A light source unit (30) is provided with light source parts (300), a fixable member (31) and a positioning member (32). Each light source part comprises a submount (302,303) receiving a bare chip (301) of a laser diode thereon and a collimator lens (306) collimating laser beam emitted from the bare chip of the laser diode for defining the emitting direction. The plurality of light source parts are directly fixed to the fixable member consisting (31) of a member having excellent thermal conductivity for quickly transmitting generated heat to a cooling unit (33) and radiating the same and having a wiring function (305) for supplying current to the light source parts. The positioning member (32) has lens holes on prescribed positions so that the collimator lenses (306) of the light source parts are fit therein for positioning the light source parts. Thus, a light source unit, having a plurality of channels, improving the degree of integration and precision of laser diodes and an image recorder employing the same can be provided. <IMAGE> |
