An information reading apparatus reads information on a recording sheet. The apparatus includes a first information reading unit that reads information recorded on one side of an information sheet. A second information reading unit reads information recorded on the other side of the information sheet. An information sheet conveying unit conveys the information sheet to the second information reading unit via the first information reading unit. A control unit controls one of the first information reading unit and the second information reading unit to re-read the information sheet when the other information reading unit is unable to read the information.
