摘要：
A light projecting device includes a base board, a light guiding member, a holding member, a cover, and a positioning member. A plurality of light-emitting elements are arranged in a line on the base board in a main scan direction. The light guiding member faces a radiation surface of the light-emitting elements and guides light projected from the light-emitting elements to an irradiation region of an illuminated object. The holding member holds the base board. The cover covers the base board and the light guiding member. The positioning member positions the light guiding member on the holding member. The holding member and the cover sandwich the light guiding member positioned by the positioning member. The light projecting device includes the holding member, the light guiding member, the base board, and the cover as a single unit which is detachably mountable relative to a chassis of the light projecting device.
