    摘要: A slider tester includes a driving unit that rotates a test medium, a set plate that detachably supports a slider as a single body, and an investigating apparatus that is electrically connected to the slider supported by the set plate and investigates the characteristics of the slider. A movable support part 30 that tiltably supports the slider is provided on the set plate. There is also provided a pressing mechanism that elastically presses the slider via the movable support part toward a surface of the medium to dispose the slider floating over the surface of the medium. The pressing mechanism includes an elastic body 56 composed of a plate spring that contacts the movable support part and elastically presses the movable support part.

    摘要: There is provided a scanning optical system, which is provided with a light source that emits at least one beam, a polygonal mirror, and an imaging optical system that converges the at least one beam deflected by the polygonal mirror to form at least one beam spot on a surface to be scanned. The at least one beam incident on the polygonal mirror is inclined in an auxiliary scanning direction which is perpendicular to the main scanning direction. Further, at least one lens surface of the imaging optical system is configured such that a beam reflected therefrom proceeds toward an outside region of the polygonal mirror.

    摘要: A relative rotational angle of a rotary body is measured with respect to a reference angle. A disk rotates integrally with the rotary body. First openings are arranged about the entire circumference of the disk and spaced from one another by a predetermined pitch. A first detecting element detects the first openings and generates a first binary code. Second openings are arranged concentrically with the first openings. A second detecting element detects the second openings and generates a second binary code. A CPU computes a relative rotational angle of the rotary body in accordance with the first binary code and initializes the reference rotational angle of the rotary body in accordance with the second binary code. When the first detecting element generates the first binary code, the CPU determines the reference angle based on a combination of the first and second binary codes stored by a ROM.

    摘要: A scanning optical system is provided with a light source, a deflector that deflects a light beam emitted from the light source to scan in a main scanning direction, a scanning lens that converges the light beam deflected by the deflector on an imaging surface to form a spot which scans on the imaging surface in the main scanning direction, and a mirror arranged between the deflector and the imaging surface, the mirror bending an optical path of the laser beam between the deflector and the imaging surface. With this structure, the reflecting surface of the mirror has a diffraction surface to compensate for lateral chromatic aberration generated by the scanning lens.

    摘要: Disclosed is a laser scanning optical system wherein light emitted from a laser source is deflected by a polygonal mirror to a scanning target surface via an imaging optical system. The laser source, the polygonal mirror, and the imaging optical system are arranged such that a stationary ghost image formed by an m-th reflection surface is formed out of the light source side end of an effective scanning range on the target surface, and a stationary ghost image formed by an (m+1)-th reflection surface is formed out of the other end of the effective scanning range.
