    摘要： A scanning optical system has a drawing light source, a rotary scanning deflector, a scanning lens and a detection device for detecting a rotational position of the scanning deflector. The drawing light source is controlled by a timing control signal generated by a timing control device as a function of drawing data. The scanning optical system may have a transmission scale, a scanning light receiving portion and a diffusion plate disposed between transmission scale and scanning light receiving portion and adapted to diffuse the monitor beam made incident to the scanning light receiving portion.

    摘要： A scanning optical system projects a light beam from a light source as a line spread function image in a principal scanning plane before the light beam is made incident onto a scanning deflector. A static deflector is disposed in a line spread function image position to guide a light beam from a light source to the scanning deflector. The static deflector has a slit mirror for reflecting a light beam from the light source or a mirror with a slit for permitting a light beam to be transmitted therethrough.

    摘要： An exposure apparatus where a mask table having an exposing pattern and a work to be exposed are relative to each other movable, wherein the moving amount of the mask table is detected by a scale image formed through a projection lens system, so that even if the projection lens system has a magnification error, by optically offsetting it, the moving amount of the mask table can be detected. Thus, a more accurate control can be obtained so that a mask image can be more precisely reproduced on a work.

    摘要： A scanning optical system for use in a laser beam printer which is small and available at low cost, and yet is capable of effectively compensating for tilting and beam shaping. The scanning lens unit in this optical system has two-element composition consisting of, in order from a deflector side, a first lens of a negative lens element having a concave spherical surface on the deflector side and a concave cylindrical surface oon the scanning surface side having a curvature in the auxiliary scanning cross section, and the second lens having a planar surface on the deflector side and a convex toric surface on the scanning surface side which has a stronger curvature in the auxiliary scanning cross section. The scanning lens unit has a shorter focal length in the auxiliary scanning cross section than in the main scanning direction and forms an image at a finite distance with the object point lying at focusing point where image is formed by the cylindrical lens. Thus, the scanning lens unit greatly reduces the effects of tilting of the deflector positioned between the focusing point and the scanning lens unit.

    摘要： An optical system particularly for a laser beam printer comprising a semiconductor laser, a collimating lens, a cylindrical lens having curvature in the sub-scanning cross section, a deflector and anamorphic scanning lens system concentrating the light on a scanning plane. The anamorphic scanning lens system may have one to four lenses but has one lens with a convex toric surface facing the scanning plane. The anamorphic scanning lens system has stronger power in the sub-scanning cross section than in the main scanning cross section.
