    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.
