摘要： The present invention relates to a scanner and a method of conveying and scanning photographic media. In the invention, an entrance roller pair and an exit roller pair are used to convey the photographic media thorough the scanner. The entrance roller pair and the exit roller pair each include idler rollers that can be selective moved toward their respective drive rollers and away from their respective drive rollers so as to selectively provide for an engaged or a disengaged position for each of the entrance roller pair and the exit roller pair. With the system of the present invention it is possible to lift the idler rollers before the leading and trailing edges of the media passes over the respective drive rollers to thus minimize any disturbance of media motion during scanning.
