摘要： An image reader is adapted to read an image represented on a document. The image reader comprises a reading unit, an LEDs driving circuit, and means for moving the reading unit and the document relatively. The above reading unit comprises an LEDs array arranged in a straight line as light sources, a rod lens array for guiding the light emitted from each LED of the LEDs array and focusing the light on the document, and a pair of photosensors being disposed in parallel and connected in parallel with respect to each other for converting a reflected light from the document to a photocurrent. And each LED of the LEDs array is turned on only one at a time sequentially by means of the LEDs driving circuit, then the reading of the document is effected by means of the photosensors.
