    Abstract: An irradiation device includes a light source that performs irradiation with light, a refraction portion that has a curved region and is arranged at a position at which the curved region is directly irradiated with the light from the light source, and refracts the light of the irradiation from the light source, and a light reception portion that is arranged at a position, which is adjacent to the light source and at which reflective light reflected by the curved region after the irradiation from the light source is received, and that receives the reflective light.

    Abstract: A light-emitting device includes a wiring substrate, a base member provided on the wiring substrate, a light-emitting element array that has a first side surface and a second side surface facing each other, that has a third side surface and a fourth side surface facing each other and connecting the first side surface and the second side surface, and that is provided on the base member, a drive unit that is provided on the wiring substrate at a side of the first side surface and drives the light-emitting element array, a first circuit element that is provided on the base member at the side of the first side surface, a second circuit element that is provided on the base member at a side of the second side surface and has a larger occupation area on the base member than the first circuit element, and wiring members that are provided at a side of the third side surface and at a side of the fourth side surface and extend from an upper surface electrode of the light-emitting element array toward an outer side of the light-emitting element array.

    Abstract: A light-emitting element array includes multiple light-emission instruction units arranged in a first direction; a first light-emitting element group row including light-emitting element groups each including a multiple light-emitting elements such that the light-emitting element groups are arranged in a direction intersecting the first direction; a second light-emitting element group row including light-emitting element groups each including a multiple light-emitting elements such that the second light-emitting element group row is arranged along the first light-emitting element group row in the first direction; and a multiple wiring lines that connect the multiple light-emission instruction units to the light-emitting element groups in the first light-emitting element group row and the light-emitting element groups in the second light-emitting element group row to provide a light-emission instruction. The multiple wiring lines are connected such that in response to the multiple light-emission instruction units sequentially providing a light-emission instruction in the first direction, the light-emitting element groups in the first light-emitting element group row sequentially emit light in the direction intersecting the first direction and, after turning on of the first light-emitting element group row is completed, the light-emitting element groups in the second light-emitting element group row sequentially emit light in the direction intersecting the first direction.
