Abstract
Abstract There is disclosed a print head with selectively settable printing bands, a selector for selectively driving any one of the printing bands, a wheel for supporting the printing band at the printing zone, brackets for adjusting the amount of tension in the bands, flexible resilient fingers for detenting the wheel, and flexible resilient fingers for diminishing increases in the tension in the bands during printing band selection.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
194 words
Printing apparatus, comprising: a plurality of flexible endless printing bands, each printing band having printing elements on its outer side and teeth formed on its underside; means for mounting the printing bands including a plurality of side-by-side multi-sided wheels for supporting the respective printing elements of each printing band at a printing zone and a plurality of side-by-side driven wheels, each driven wheel having a plurality of spaced apart notches engaged by the teeth of a respective printing band, a mounting block having at least one independent spring finger in resilient engagement with each printing band to diminish the increase in tension in the printing band as the driven wheel and the multi-sided wheel rotate, and rollers mounted by the mounting block for supporting the driven wheels and cooperable with the notches in the driven wheels for detenting the printing bands; flexible resilient means molded integrally with the mounting block for independently detenting each multi-sided wheel, means for adjusting the tension on the printing bands, and a selector having an integrally molded drive lug drivingly cooperable with any one of the driven wheels to effect selective setting of any one of the printing bands.

Claim 3
Dependent Claim
146 words
Printing apparatus, comprising: a plurality of flexible printing bands each having a plurality of printing elements, spaced-apart teeth formed on the underside of each printing band, means for mounting each printing band under tension including a molded plastic block in contact with the printing bands and drive wheels for advancing the respective printing bands, and a plurality of pairs of opposed, independent, flexible, resilient spring fingers molded integrally with the plastic block, each pair of spring fingers acting in opposite directions on the respective printing band by resilient contact with the underside of the printing band at opposed locations to compensate for manufacturing tolerances in the respective printing band and to diminish the increase in tension as the respective drive wheel is rotated to bring another of the printing elements to the printing zone, the oppositely acting spring fingers exerting opposite forces on the printing band.
