    摘要: An improved drive for a scanning optical system in a photocopier is disclosed. The drive incorporates an adjustable capstan and precision tapes as well as cables. The precision tapes are used between the two carriages which mount the optics because precise control of length in this portion of the system is critical. Cables are used in the remainder of the drive where flexibility in all directions is important. There is also a single drive embodiment. Also disclosed is a method for proper alignment of the carriages after field replacement of a broken cable.

    摘要: A continuously variable reduction optical system for document copiers including various embodiments. A scanning optical system embodiment is disclosed for corner referenced documents. Full-exposure optical system embodiments are disclosed for both single-edge referenced and corner referenced documents. The systems can make use of single focus lens or variable focus lens. Specific mechanisms are disclosed for continuously variable adjustments to magnification, to total conjugate length, to image position, to scan speed and scan length and to leading edge registration. All adjustments are tied together under the control of the machine operator.
