SOLUTION: A surface of the light source 10, specifically, a -y side face of a package 10b, is brought into pressure contact with a bottom wall face of a recess 74b formed in the first holder 74, by biasing a substrate 76 to the first holder 74 by a bias member 78.

A positional relationship between the substrate 76 and the first holder 74 is also kept constant by fixing a holding member 77 onto the first holder 74 under the condition where a grasping part grasps the substrate 76. The positional relation between a coupling lens 11 (optical element) supported by the second holder 72 and the light source 10 is thereby maintained at constant as a result thereof.

摘要： PROBLEM TO BE SOLVED: To improve the using efficiency of a light beam without entailing a higher cost of the apparatus.
SOLUTION: The light quantity control of a light source 10 is performed by monitoring the luminous flux not contributing to scanning among the luminous fluxes of the light beam. Thereby, the light quantity control of the light source 10 can be performed without degrading the using efficiency of the light beam contributing to the scanning. Also, the light beam is guided by a protection member 71 to a photodetector 18. Accordingly, the need for using an element, such as a beam splitter, for branching the light beam from the light source 10 is eliminated and the cost reduction of the apparatus is achieved.
