ABSTRACT:
A copying machine for copying a document in two-in-one mode comprises a scale (120), an automatic document feeder (ADF) (60), a document selection key (105) and a control circuit (CPU2). A scale (120) is arranged upstream or downstream of the glass platen (29) in the document conveying direction and protruded upward from an upper surface of the glass platen (29). The ADF (60) has a first mode and a second mode. In the first mode the ADF (60) conveys two document sheets to an exposure position (SP) with their ends made coincident with each other without restricting them by the scale (120). In the second mode the ADF (60) conveys two documents sheets on the glass platen (29) with an interval provided therebetween and making the ends of the two document sheets coincident with each other by restricting one of the two sheets arranged on one side close to the scale (120). The ADF (60) is controlled by the control circuit (CPU2) in the mode selected by the document selection key (105) according to the quality of the document.
