Abstract
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.
