Abstract: An image reading device reads a document using a plurality of reading modes including a sheet-through reading mode for reading a document at a fixed reading position while the document is automatically fed. The image reading device includes a first resolution changer, a second resolution changer, and a resolution setting unit. The first resolution changer changes one of a linear velocity at which the document is fed and a traveling speed of a reading carriage to change a resolution at which the document is read in a sub-scanning direction. The second resolution changer electrically interpolates image data output from the first resolution changer to change a resolution of the image data. The resolution setting unit provides a plurality of combinations of resolution change rates between the resolution changers as resolution change modes and sets the resolution changers to one of the combinations of resolution change rates.

Abstract: An apparatus for illuminating a photoconductive surface. The apparatus includes a housing defining a chamber and an open end. An imaging device is placed in the housing chamber. The imager transmits light rays through the open end of the housing to the photoconductive surface. An air pump is coupled to the housing. The air pump maintains an outwardly directed flow of air from the open end of the housing so as to move particles away from the open end. Electrically biased electrodes are located between the imaging device and the photoconductive surface. They attract the particles so as to prevent the particles from contaminating the imaging device.
