    摘要: For preventing occurrence of interference fringes derived from interference of light rays on a contact plane between a contact glass and a cover glass, and thus homogenizing an output wave that may otherwise undergo the adverse effect of interference fringes, a close-contact type image sensor includes a contact glass arranged to come into contact with a read surface of an original, a light source for irradiating light to the read surface, an image forming lens for converging light reflected from the read surface, an image sensor part for reading an image of the original formed on an image plane of the image forming lens, and a cover glass for fixing the light source and the image forming lens at respective predetermined positions in a housing, wherein an air layer is present between the contact glass and the cover glass.

    摘要: There is an image reading apparatus for use in a facsimile apparatus, a copying machine or the like. This apparatus illuminates the light from a light source such as an LED array onto an original which is conveyed by a conveying device and thereby reading an image data on the original. To smoothly guide the edge of the original, an original guiding device which guides the original non-rippingly is provided downstream of the position where the original is read in the original conveying direction by the conveying device. As an original guiding device, a flat or concave guide surface, a flat or concave notch, original guide rollers, a guide member having a concave surface, or the like is provided. The guiding device may if desired be light-reflective.

    摘要: An image reading apparatus for reading an image by radiating the light onto an original includes a photosensor array the photosensors of which are arranged along the width of the original and receive the light scattered from the original surface and convert that light into electric signals. A period of time from the time when the photosensors receive the light until outputs containing the read information are derived cannot be ignored as compared with a reading scan time when the signals are read from the photosensor. A light source is arranged along the width of the original and is divided into a plurality of. A light-on controller for lighting the blocks of the light source to illuminate pixels for the reading of an image on the original, in advance of the reading of the pixels, for a time interval over neater than the foregoing period of time. In this apparatus, only a single LED array is used, so that the arrangement of the apparatus is simplified and the cost of the apparatus and its operating cost are also reduced.
