摘要： In a reflective scanning optical system employing an imaging optical system having a curved mirror with a rotationally symmetrical reflecting surface configuration, the change in magnification of the imaging optical system in the auxiliary scanning direction is reduced and thereby the beam spot diameter on the scan target surface is equalized, as well as equalizing the scan line interval on the scan target surface when the system is applied to a multibeam scanning optical system. The imaging optical system of the reflective scanning optical system includes a curved mirror with a rotationally symmetrical reflecting surface and a lens having an anamorphic lens surface configuration on its one side. In the anamorphic lens surface configuration, slope and curvature of the line of intersection of the lens surface and a plane parallel to the auxiliary scanning cross section change independently of each other as the position in the main scanning direction changes.

摘要： A rotary filter type particulate removing device is provided. A rotary cylinder (2) rotates in a stationary cylinder (1) to change an exhaust gas introduced into the stationary cylinder (1) to a circulating flow so as to apply a centrifugal force on particulates in the exhaust gas in order to collect the particulates circulating in the stationary cylinder (1) into a trap (15) provided at a lower part of the particulate removing device. A filter is located on an inner wall of the rotary cylinder (2) and a huge number of punching holes (8) are formed in the lateral wall of the rotary cylinder. A fan (7) is secured on the rotary cylinder (2) which projects to the outside from the stationary cylinder (1) to constitute a sirocco fan. The exhaust gas passes through the punching holes (8) of the rotary cylinder (2) and flows into the interior of the filter. The exhaust gas further flows towards the sirocco fan. Then, the exhaust gas passes the filter again, and is discharged to the outside through the punching holes (8) of the rotary cylinder (2).

摘要： Laser beams emitted from a plurality of light emitting points of a light source unit are converged by a first optical system to be focused in an auxiliary scanning direction in the vicinity of a reflecting surface of a polygon mirror, dynamically deflected by the polygon mirror, and converged by a second optical system to form scan lines on a scan target surface. The first optical system includes a plurality of cylindrical lenses, in which a second cylindrical lens is attached to a holder so as to be movable in the optical axis direction and is selectively stopped at two positions that satisfy a particular relationship. By the composition, the interval between the scan lines on the scan target surface measured in the auxiliary scanning direction can be switched correctly and with extreme ease in the multibeam optical system, without the need of using a movement control mechanism composed of high precision parts.

摘要： A scanning optical system includes a light source for emitting a beam of light and a first optical system that changes a cross-sectional shape of the beam into an oblong shape along a main scanning direction. A light deflector deflects the oblong cross-sectioned beam of light in the main scanning direction, and a second optical system receives a beam of light deflected by the light deflector for focusing the deflected beam of light onto a scanning surface. At least one surface of a lens in the first optical system is formed as a sub-scanning-plane aspherical surface so as to correct the spherical aberration of the scanning optical system in a sub-scanning direction caused by the second optical system.
