ABSTRACT:
The invention is directed to an apparatus for recording image information on both sides of recording sheets which, lying against a partial circumference of a print roller are conducted past an image recording unit. A format of the inventive apparatus which is particularly simple in structural terms is achieved in that a sheet seating surface approaches the underside of the print roller upon formation of a sheet draw-in gap which lies preceding the image recording unit as seen in the rotational sense of the print roller and in that a sheet guidance surface forming a sheet acceptance gap together with the print roller and following the image recording unit as seen in the rotational sense of the print roller is arranged across the print roller and approaches the sheet seating surface at an acute angle.
