Abstract
The copying machine permits a selective use of either a single sheet original, or a file original such as a book, and in which an original is moved by means of rollers for scanning an image thereof. A plurality of drive rollers are disposed on the under side of a path of movement of an original to be copied, whereas mating driven rollers are mounted on a movable frame so that they can be retracted from their normal position when a file original is used. The frame is manually moved to the retracted position without substantial change in its posture, thereby permitting an operator to easily operate the frame. After the frame is retracted, a file original may be placed on a transparent sheet member which is arranged to be fed on the drive roller so as to be moved thereby for scanning.
