Abstract: A device which can feed originals from a holder via a feed path to an exposure window using a cooperating pair of rollers and a conveyor device, the direction of movement of which can be reversed to allow returning of the originals via a discharge path to the holder. The pair of rollers is provided with a drive mechanism and a coupling belt which, during conveyance of an original to the exposure window, convey the original to and on the window in cooperation with the conveyor device and which stop the pair of rollers or reverse the direction of movement of the rollers during the conveyance of an original from the exposure window to the discharge path in order to inhibit feeding of the new original on one hand, and to position the new original on the other hand. There is a fixed time relation between the times at which the states of the movement of the pair of rollers and the conveyor device change.

Abstract: A copying machine is provided with a sheet stapling device for both automatically fastening together in a corner area a bundle of sheets successively printed in the copying machine and fastening together a bundle of sheets manually inserted in an externally accessible opening formed in the side of the stapling device. Preferably, the opening is formed by an elongated slot which extends to the operating side of the copying machine and which coincides with the opening through which sheets printed in the copying machine are discharged from the stapling device. A bundle of sheets can be inserted in the opening so that any edge part is under the stapling means. Thus, the inserted bundle can be stapled at different places along any edge. The opening is provided with two detectors to determine when a bundle of sheets inserted manually is correctly positioned under the stapling device and to initiate the stapling action.
