US 2023/0408700 A1 · OPTICAL DISTANCE-MEASURING DEVICE AND IMAGE FORMING APPARATUS

Abstract

An optical distance-measuring device includes: a light emitter having plural light-emitting areas that are arrayed in a first direction; an optical system provided at a position toward which the light emitter emits light, the optical system causing light beams respectively emitted from the plural light-emitting areas to be deflected in respectively different directions; and a detector including plural detecting elements configured to detect a reflection of light outgoing from the optical system. Detecting directions of some of the plural detecting elements are different from detecting directions of others of the plural detecting elements in the first direction.
