Abstract (en)

[origin: US5360276A] PCT No. PCT/EP91/01484 Sec. 371 Date Feb. 10, 1993 Sec. 102(e) Date Feb. 10, 1993 PCT Filed Aug. 6, 1991 PCT Pub. No. WO92/02370 PCT Pub. Date Feb. 20, 1992.In a printing device having an abutment (10) intended for supporting a recording medium (52), a print head (32) which is movable relative to the abutment (10) in the direction of the lines, an actuating drive (28, 26, 24) for setting the print head distance relative to the abutment (10) and a pressing element (36) which extends the full width of the recording medium and presses the recording medium (52) onto the abutment (10) and can be deflected in accordance with the thickness of the recording medium (52), a magnet (54) is arranged on one of the parts (pressing element 36, part 46 fixed to the print head) and at least one Hall probe (56) is arranged on the respective other part (part 46 fixed to the print head, pressing element 36) in such a way that the magnet (54) and the Hall probe (56) can be brought into congruence with one another in a predetermined print head position corresponding to a measurement position, a circuit arrangement (60) being provided to measure the Hall voltage and to regulate the latter to a predetermined value (intended Hall voltage), which circuit arrangement controls the actuating drive (28, 26, 24) of the print head (32) as a function of a difference between the actual Hall voltage and the intended Hall voltage.
