Abstract

A copying machine including a paper sheet deflecting device is disclosed. For compact copying machines an excessively curved sheet deflection is achieved for a space-saving construction. In order to reliably and independently of the type of sheets ensure a deflection with a relatively pronounced curvature, the deflecting device of the new copying machine is constructed as a guiding element which partially surrounds a withdrawal roller and which, while leaving an introducing gap, rests with a predetermined contact force against the circumference of the withdrawal roller. The resulting active contact pressure force on the withdrawal roller for the sheet to be drawn in permits a secure paper transport with a simultaneous deflection with a small radius of curvature.
