    Abstract: Coherence of an optical fiber bundle with randomly different geometries at its two ends is achieved electronically. A photosensitive random access memory is used as a sensor array to determine the addresses of fiber at which light exits when light is sequentially directed into consecutive fibers at the other end. The addresses are stored in a ROM and used to provide coherence of an otherwise unordered fiber optic bundle having one end formed in a linear array, for example, and used to scan documents. A printer also is described using electronically acieved coherence.

    Abstract: An image input device is disclosed including an image source which generates an image light and a light sensor facing the image source. The image light is divided into a number of components by an image dividing device. The light sensor contains a number of photoelectric converting elements, the number of photoelectric converting elements being smaller than the number of components constituting the image light. The image dividing device is placed between the light sensor and the image source to divide the image light into components in a predetermined timed order. The photoelectric converting elements are thereby irradiated in the predetermined timed order and the electrical signals generated by these photoelectric elements are read out in this same predetermined timed order and stored in a memory.

    Abstract: An image reading apparatus includes a light guide including a light guide portion configured to guide light emitted from a plurality of light sources, a deflection portion configured to deflect and emit light guided by the light guide portion, and a projection portion. The light guide portion includes a first surface and a second surface configured to internally reflect the light from the light sources. At least one of the first surface and the second surface includes a concave portion positioned to cover the projection portion in the arrangement direction. In a plane passing through the concave portion and parallel to the arrangement direction, a distance between the first surface and the second surface in a portion where the concave portion is formed is smaller than a distance between the first surface and the second surface in a portion where the concave portion is not formed.
