Abstract

A feed arrangement for transporting a record carrier around and in intimate contact with a printing platen in a printer. The feed arrangement includes a rotatable guiding member in the form of a paddle wheel having a number of resilient blades mounted in interference relationship to the platen. The guiding member serves to capture the leading edge of the record carrier and redirect it toward and then urge it into intimate contact with the platen.

Claims

1. A record carrier feed arrangement for a printer having a platen rotatable about a first axis for serially transporting record carrier sheets past a printing region and against which each record carrier sheet is to be urged in intimate contact, wherein the leading edge of the record carrier sheet, when transported by said platen, diverges therefrom in the vicinity of said printing region, said feed arrangement being characterized by including

guiding means rotatable about a second axis, said guiding means comprising a set of peripherally spaced resilient members, extending outwardly from said axis, between which the record carrier leading edge may be captured, by which it may be redirected toward said platen as it diverges from said platen, downstream of said printing region, and by which it may be urged into intimate contact with said platen, said first and second axes being fixed relative to one another and being positioned so that the ends of said peripherally spaced members blades interfere with the surface of said platen.

2. The record carrier feed arrangement as defined in claim 1 characterized in that said second axis is substantially parallel to and spaced from said first axis.

3. The record carrier feed arrangement as defined in claim 1 characterized in that said guiding means comprises plural sets of peripherally spaced resilient members in axially spaced relationship to one another.

4. The record carrier feed arrangement as defined in claim 2 characterized in that said peripherally spaced members are substantially coextensive with said platen.

5. The record carrier feed arrangement as defined in claim 2 or 3 characterized in that said peripherally spaced members are driven in a direction opposite to the direction of said platen.

6. The record carrier feed arrangement as defined in claim 5 characterized in that said peripherally spaced members are driven at a rate faster than the rate of said platen.
