Arrangement for guiding a printer carriage in an ink jet printer

摘要

The invention relates to an arrangement for guiding a printer carriage (20) in an ink jet printer. Starting from a paper guide (11) which is mounted resiliently on a transporting roller (10) for transporting a recording medium (12), it is proposed to mount the printer carriage (20) near to its centre of gravity (40) at a first and a second guide point (31, 32) so as to be pivotable and displaceable on a guide rod (30). Furthermore, a guide knob (23) is provided, which is mounted as a third guide point (33) on the paper guide (11). It is proposed optionally to provide a fourth guide point (34) which is supported resiliently on a frame (50). Due to the changing material thickness of the recording medium (12) as well as production tolerances and wear, the printer carriage (20) is pivoted about the axis of the guide rod (30) and the distance of the nozzle outlet surface (22) from the surface of the recording medium (12) is thus kept constant. <IMAGE>
