Abstract

A light beam emitting apparatus including: a light source having plural light emitting points emitting beams; and a holding member configured to hold the source and having first, second, and third abutment portions, an emission direction of the beams being regulated by the abutment portions in abutment with the source, wherein as viewed along an optical path of the beams, an angle formed by a first line connecting two farthest light emitting points with a second line connecting the first and second abutment portions is smaller than angles formed by the first line with a third line connecting the second and third abutment portions and formed by the first line with a fourth line connecting the third and first abutment portions, and a distance between the first and second abutment portions is larger than distances between the second and third abutment portions and between the third and first abutment portions.
