A polygon mirror includes a mounting portion and a plurality of reflective surfaces. The mounting portion is mounted on a rotating body having a support surface. The mounting portion has the shape of a polygonal plate. The plurality of reflective surfaces are arranged around the rotating body so as to surround the rotating body. A plurality of protrusions configured to abut against the support surface of the rotating body are arranged on one side of the mounting portion.

A polygon mirror includes a reflective surface group having n number of reflective surfaces (M(), . . . , M(n)) formed individually as outer peripheral side faces, a flat portion which shuts one end portion of the reflective surface group, and n number of pin gate traces (L(), . . . , L(n)) which are provided on the flat portion, correspond to the n number of reflective surfaces, individually, and are kept individually at distances from edge portions at which the reflective surfaces cross the flat portion. There are conditions DM()&#x3e;DL()/, . . . , DM(n)&#x3e;DL(n)/and DM()&#x3e;DL(n)/, . . . , DM(n)&#x3e;DL(n&#x2212;1)/, where DM(n) is a shortest distance from an edge portion at which the reflective surface M(n) and the flat portion cross each other to the pin gate trace L(n) and DL(n) is a shortest distance between the pin gate trace L(n) and the pin gate trace L().

A temperature control system has a light intensity detection device for providing temperature compensation in accordance with the variation in angle of incident sunlight. The light intensity detection device includes a photoelectric device having a light receiving surface and which produces an electrical output signal in accordance with the intensity of received light. An optical device is disposed between a light source and the light receiving surface. Incident light transmitted through the optical device is re-directed to the light receiving surface by a plurality of prism surfaces disposed on the optical device facing the photoelectric device. The prism surfaces may be concentrically arranged around the optical axis of the photoelectric device. The surface area and angle of orientation of respective prism surfaces are predetermined such that the output electrical signal of the photoelectric device corresponds to a predetermined function in accordance with the thermal energy produced in the vicinity of the light intensity detection device as a function of the angle of incidence of incident light. Thus, the temperature, for example, in an automobile cabin may be precisely and accurately controlled and any variation in thermal energy within the interior of the cabin due to incident light may be compensated for.
