Abstract
An improved paper feed roller assembly for the paper feed mechanism of a printer is provided with an adjustable arrangement so that a plurality of different widths of perforated edge paper may be accommodated thereby. The arrangement includes a rotatable member having a plurality of indentations which cooperate with stops to select an axial position for the feed pins mounted on the roller, corresponding to the selected indentation.
Claims19
In a web feeding mechanism a roller assembly for accommodating any one of a plurality of webs of differing widths and having feed holes, comprising:
- an elongated cylindrical shaped roller;
- a sleeve coaxially mounted on said roller and axially slidable thereon and having a plurality of radially extending pins spaced circumferentially thereabout and adapted for engagement with the feed holes of said web;
- resilient means for normally urging said sleeve in a predetermined axial direction along said roller;
- and
- said sleeve including positioning means for axially positioning said sleeve along said roller, said positioning means being adjustable to one of a plurality of precise predetermined positions, said resilient means being adapted to retain said positioning means in its selected position said positioning means including indentations arranged along one edge of said sleeve and being of differing depths and projection means on said roller cooperating with said indentations for axially positioning said first sleeve according to the indentation aligned with said projection.
In a paper feed roller assembly for printers and the like including a roller and a pair of spaced apart sleeves mounted on said roller for rotation therewith, said sleeves including pins for feeding engagement with paper having feed holes along opposite longitudinal edges, an arrangement for selectively setting the axial spacing between said sleeves including adjustable positioning means associated with each of said sleeves, each of said positioning means comprising a plurality of indentations arranged about said sleeves each being of a respective predetermined depth;
- a stop member for each positioning means fixedly mounted on said roller and each adapted to fit within a selected indentation;
- and
- resilient means for normally urging each of said sleeves against a respective one of said stop members to maintain the respective stop member within a selected indentation.

- a pair of adjustable positioning sleeves mounted on the roller, each of said positioning sleeves having a plurality of indentations each of a respective predetermined depth;
- a stop member for each positioning sleeve fixedly mounted on said roller and each adapted to fit within a selected indentation portion of a respective positioning sleeve;
- and
- resilient means for normally urging each of said paper feed sleeves against a respective one of said positioning sleeves so as to maintain the respective stop member within a selected indentation.
