ABSTRACT:
An imaging device of the present invention includes a separating unit for separating a stack of original documents one by one. The separating unit feeds the separated document to a reading unit capable of reading an image out of the document. To insure stable operation of both the separating unit and reading unit, the separating unit and reading unit are respectively provided with an exclusive separating motor and an exclusive reading motor. A first transporting roller is included in the separating unit and rotated at a speed equal to or higher than the rotation speed of a second transporting roller included in the reading unit. This insures stable transport of the document from the separating unit to the reading unit. Even when any drive element included in the separating unit fluctuates, drive elements included in the reading unit are free from the influence of the fluctuation.
