The compact design of a CIS device is exploited, resulting in a more compact scanning mechanism and in lighter and smaller scanning devices. The CIS is incorporated into a drive belt attached to the length of the CIS. The CIS is forced to traverse the document by a drive mechanism that pulls the entire belt and CIS across the document while maintaining the tension necessary to keep the document in the narrow depth of focus. This mechanism provides a uniform force on the CIS, reducing the possibility of yawing motion, and keeps the document in focus through the tension on the drive belt. The combined CIS and transport mechanism power requirements can be supplied by standard computer interfaces, requiring no additional power supplies. This new mechanism also hides the internal workings of the scanner behind a drive belt that is the size of the platen window. The drive belt can either be printed to present the operator with instructions or markings to indicate document placement or with other information, or the drive belt can be left blank to present the operator with a cleaner and less cluttered scanning device.
