    Abstract: A raster input scanner, and a reproduction system that uses that input scanner, having multiple depths of focus. The raster input scanner includes a light source for emitting light toward an image bearing member and at least two lens arrays, with the ability to selectably position any one lens array in optical conjugate relationship between the image bearing member on a transparent platen and a photosensor array. One of the lens arrays has a first depth of focus, while the other lens array has a second depth of focus that is different than the first depth of focus. Beneficially, the input scanner responds to an operator selection of which depth of focus is to be used to image a given image bearing member.

    Abstract: An image reading system for optically reading an original includes a convergent type light-emitting diode array as a light source, a white level reference and an image sensor disposed opposite to the white level reference. The light emitted from the LED array has a light intensity distribution which reduces in level in a transverse direction from an irradiation axis. The LED array is preferably so disposed with its irradiation axis passing a mid-point between the white level reference and an intersection point between an original surface travelling line and a straight line extending between the white level reference and the image sensor.
