摘要： A scanning device for scanning an original which is set at a predetermined position and has information recorded thereon comprises: a plurality of light emission members for emitting lights of different wavelengths from each other; a first reflection member having a plurality of reflection planes for selectively reflecting emitted lights of a plurality of wavelengths coming from the light emission members and an optical aid portion; a second reflection member for reflecting the lights reflected by the first reflection member to focus them on the original in a linear pattern; and an imaging optical system for focusing the lights of the linear pattern onto a sensor, whereby the sensor receives the information of the original. The device has depressions arranged around the light emission members for reflecting lights and the depressions are shaped differently depending on increased wavelengths of the light emissions of the corresponding light emission members so that the light intensities of the respective wavelengths of light emissions and decreased non-uniformity of the light intensity are attained.
