Abstract:
1. A printer, comprising a plurality of printing bands, each printing band bearing a plurality of print types and each printing band being positively guided around a single selector wheel and each printing band also being guided around a single counter-pressure element, each counter-pressure element being spaced apart from the corresponding selector wheel, wherein selected print types are set into printing position on the counter-pressure elements by rotation of the selector wheels, the selector wheels having engagement recesses and stop members associated with the selector wheels, such that the stop members elastically engage in one of the engagement recesses when a printing position is reached, thereby fixing the selector wheels and hence the printing bands in the printing position, wherein the stop members comprise a comb-shaped stop spring having individual elastic tongues with one of the elastic tongues being assigned to each selector wheel, each of the elastic tongues having a section that engages in a respective engagement recess of a respective selector wheel, wherein the sections have an arcuate surface that is in substantially full facing engagement with an arcuate surface of the respective engagement recesses, wherein the elastic tongues are formed on a common base part, the tongues having a spacing equal to a spacing of the selector wheels, wherein the elastic tongues and the base part are comprised of spring sheet steel and a retaining block is arranged between the selector wheels and counter-pressure elements of the printer, the retaining block having a slot into which the common base part positively engages by being inserted into the slot from above.
