Abstract: An optical measuring apparatus includes first and second light-emitting elements that emit light and a controller. Upon detection of the presence of a body by light emitted from the first light-emitting element, the controller performs control so that the second light-emitting element will emit light with an amount for measuring the body.

Abstract: A light-emitting device includes a light-emitting unit. The light-emitting unit includes an array of multiple light-emitting element groups, each including multiple light-emitting elements. In the light-emitting unit, the multiple light-emitting element groups are sequentially driven along the array such that, for each of the multiple light-emitting element groups, the multiple light-emitting elements included in the light-emitting element group are concurrently set to a state of emitting light or a state of not emitting light.
