<P>PROBLEM TO BE SOLVED: To provide a light-emitting element adjusting and fixing structure capable of facilitating a jig configuration, preventing an optical axis and a beam pitch of the light-emitting element from changing in an adjustment and fixing, and holding the light-emitting element for adjusting the rotation. <P>SOLUTION: A light-emitting element adjusting and fixing structure adjusts a distance between respective light-emitting points P1 and P2 by rotating a light-emitting element 9 having a flange portion 9a and the plurality of light-emitting points P1 and P2 around an optical axis of the light-emitting points P1 and P2, and fixes the light-emitting element 9 to a housing 7. The housing 7 includes a mounting hole 7c having a reference plane 7b to which the light-emitting element 9 is mounted, and the mounting hole 7c has a holding portion 21a which rotatably holds the flange portion 9a, while bringing the flange portion in contact with the reference plane 9b. <P>COPYRIGHT: (C)2012,JPO&INPIT |
