Abstract
A projector for emitting projection light in a projection direction used in a floor set-wall projection and floor set-floor projection modes. The device includes an aspheric reflection mirror, which reflects light from a light source in the projection direction, and a case, which accommodates the mirror. The mirror reflects the projection light to emit the projection light through an opening in the case. The case includes a first setting surface, which is arranged adjacent to a floor when in the floor set-wall projection mode, and a second setting surface, which is arranged adjacent to the floor when in the floor set-floor projection mode. The second setting surface in the floor set-floor projection mode is located immediately below the mirror and bulges to a location that is in alignment with or frontward from a front end of the mirror.
