ABSTRACT:
The invention relates to a contact pressure mechanism for pressing or lifting a web-shaped image receiving material against or off from a drum-shaped image carrier in a toner image transfer station of an electro-photographic recording or copying device comprising a contact pressure rail extending over the width of the image receiving material which can be swiveled in and out via an electro-magnetic actuation device. The image receiving material is thereby situated in positive engagement with transport elements in the form of tractors which are arranged preceding and following the contact pressure rail. The image receiving material is conducted over a length compensating means arranged between a transport element and the contact pressure rail, said length compensation means having a seating surface for the image receiving material, whereby the length compensating means is coupled such to the contact pressure rail that the seating surface thereof executes a motion opposite the pivot motion of the contact pressure rail and thus releases or compensates the length of the image receiving material required or becoming free during the in/out-swivel of the contact pressure rail.
