Patent ID: 8755095

Claim:
An illuminating device comprising: a light-emitting element; a reflective member; and a light-guiding member that guides light emitted from the light-emitting element toward an irradiated object and the reflective member, the illuminating device illuminating the irradiated object with light that has been emitted from the light-emitting element and guided to the irradiated object by the light-guiding member and with light that has been emitted from the light-emitting element, guided by the light-guiding member and reflected to the irradiated object by the reflective member, wherein the light-emitting element and the reflective member are disposed to sandwich a path through which light reflected by the irradiated object passes, and the light-guiding member is disposed on a side of the light-emitting element relative to the path, the light-guiding member includes a direct emission unit that is disposed between the irradiated object and the light-emitting element, and through which light emitted from the light-emitting element to the irradiated object is transmitted, and an indirect emission unit that is disposed between the reflective member and the light-emitting element, and through which light emitted from the light-emitting element to the irradiated object via the reflective member is transmitted, and a light incident face of the direct emission unit and a light incident face of the indirect emission unit face to the light-emitting element, the light-emitting element is disposed on a side of an interior angle formed by the light incidence faces, and the direct emission unit and the indirect emission unit have a condensing property, wherein an area of the light incidence face of the direct emission unit differs from an area of the light incidence face of the indirect emission unit.
