Abstract
An automatic duplex electrophotographic copying machine comprises a paper supply device, a photoreceptor, a copy enabling device, a copied paper expelling device, a single-side copied paper storing device, and a selector activated for selecting the copied paper expelling device or the single-side copied paper storing device. The single-side copied paper storing device is movable to receive the single-side copy paper and supply it to the paper supply device, so that the single-side copied copy paper is transported to the photoreceptor and the copy enabling device, to copy a new image onto the other or reverse side of the paper. The selector comprises a flapper flapped for the selection. The single-side copied paper storing device comprises a paper regulating device for regulating the exact position of the paper within the device to copy the image on the exact position of the reverse side of the paper.
