Abstract: A relative rotational angle of a rotary body is measured with respect to a reference angle. First openings are arranged about the circumference of a disk, which rotates integrally with the rotary body, at predetermined pitches. A first detecting element detects the first openings and generates a first binary code. The relative rotational angle of the rotary body is computed in accordance with the first binary code. A second detecting element detects the second openings and generates a second binary code. The reference angle of the rotary body is computed and reset in accordance with the second binary code. Third openings are concentrical with the first and second openings. A third detecting element detects the third openings and generates a third binary code. The reference angle is determined based on the combination of the first and third binary codes.

Abstract: A rotor is fixed to a steering shaft to rotate with the steering shaft, and outer and inner slits are formed along different circles on the rotor. Outer and inner sensors, which detect the presence or absence of the slits, generate reflective codes and are located next to the rotor. Stored pattern data that matches the reflective code is used to determine the rotational angle. Alternatively, if the pattern data does not match the reflective codes, the rotational angle of the steering shaft is computed on the basis of the reflective codes.

Abstract: A scanning optical system is provided with a semiconductor laser, a polygonal mirror, which deflects a beam emitted from the semiconductor laser, an f&thgr; lens for converging the beam deflected by the deflector onto a surface to be scanned, and a diffractive surface between the polygonal mirror and the surface to be scanned. The diffractive surface compensates for a lateral chromatic aberration caused by the f&thgr; lens. Further, the diffraction efficiency of the diffractive surface on an optical axis of the f&thgr; lens is smaller than that of a peripheral portion to cancel a power variation due to a variation of the light quantity transmitted through the scanning lens.

Abstract: A rotational angle detector provided with a circular rotary plate integrally rotatable with a rotor of a motor and including a circumferential surface having marks, which are spaced apart by different angular intervals in a circumferential direction. A rotational angle detection unit is arranged along the circumferential direction of the rotary plate to detect a rotational angle of each mark, rotated together with the rotary plate, in a predetermined detection zone. The rotational angle detector determines, when adjacent marks are located in the detection zone, angular intervals between the adjacent marks based on the rotational angle of each mark, specifies a mark that is located in the detection zone based on the determined angular intervals, and detects the rotational angle of the rotor based on the rotational angle of the specified mark rotating in the detection zone.
