摘要： An image magnification control mechanism for a facsimile zoom lens is provided in which a position detecting section is directly coupled to a drive member for moving the optical system of the zoom lens. The positions of the lens groups are controlled by a servo mechanism controlled by a pulse signal from the detecting section which also controls the speed of the zoom lens. An address instruction detecting section is used to achieve the positioning operation quickly and accurately. In the preferred embodiment, the invention is comprised of a stationary detection slit and a rotary member having only a finite number of slits corresponding to different magnification ratios. Speed control slits are provided on either side of either the stationary or movable slits to provide signals for stepwise increasing or decreasing the zooming speed. Address slits and corresponding detectors are provided for determining which of the magnification ratios is presently being used.

摘要： An optical scanning system in which light emitted from a light source is deflected by a deflector and converged onto a surface to be scanned by an optical image forming system. The optical image forming system has a curvature of field in a sub-scanning direction to cancel a change in a beam spot diameter caused by a change in an F-number in the sub-scanning direction, depending on an image height in the main scanning direction. The invention is also addressed to a method for determining a curvature of field in the optical scanning system.
