摘要： A sheet feeding device, which is included in an image forming apparatus, includes a sheet container to accommodate a recording medium, a sheet feeding body to press a surface of the recording medium in the sheet container and feed the recording medium in a sheet conveying direction, a pair of sheet position regulators to regulate a position of the recording medium in a sheet width direction perpendicular to the sheet conveying direction, and a load applier to contact the surface of the recording medium and apply a load to the recording medium at the surface. The recording medium is brought to move toward one of the pair of sheet position regulators while the recording medium is being fed. A lower face position in a standby state of the sheet feeding body is lower than a lower face position in a standby state of the load applier.

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.
