Abstract

Shown is a simple low cost nonincrementing, clean inking supply suitable for use with segment platen printers. The platen arm is translated across the print line and this motion turns the roller journaled therein against the machine frame. The turning roller drives a porous ink disc which rotates against the ink transfer disc mounted for rotation on the platen arm. The area of contact of the ink transfer disc is treated to provide friction and hold the ink transferred from the porous ink supply disc. This results in a constant supply of ink in the area in which the print head, which may be of a wire matrix type, contacts the paper. With this arrangement, there is little obscuration of the print line and the need for ribbon feeding and reversal is eliminated.

Segment Platen Ink Disc

Shown is a simple low cost nonincrementing, clean inking supply suitable for use with segment platen printers. The platen arm is translated across the print line and this motion turns the roller journaled therein against the machine frame. The turning roller drives a porous ink disc which rotates against the ink transfer disc mounted for rotation on the platen arm. The area of contact of the ink transfer disc is treated to provide friction and hold the ink transferred from the porous ink supply disc. This results in a constant supply of ink in the area in which the print head, which may be of a wire matrix type, contacts the paper. With this arrangement, there is little obscuration of the print line and the need for ribbon feeding and reversal is eliminated. The porous ink supply disc is a relatively simple structure, and is easily replaced without requiring extensive cleanup.
