Abstract

Two pressure wheels are mounted on respective support parts and are pressed against respective edges of print medium by a common force-applying device such as a cable acting substantially equally on two mechanical devices on which the pressure wheels are mounted in order to transmit substantially identical forces thereto; each wheel may be mounted at one end of a lever which is hinged to the corresponding support part and which supports a pulley over which the cable passes.
