Abstract

Optimum spacing for a wire-matrix printer is provided by a spacer roller located in close proximity to the print head. Printed entries on a passbook 1 are made by a wire-matrix print head 2. The passbook is held in position on platen 3 by pressure clamp 4. Springs 5 urge the platen against the print head. Optimum spacing is maintained by spacing roller 6, which allows the head to be moved across the passbook as printing is accomplished. The dimensions of the rollers are such as to accommodate ribbon 7 between the passbook and the print head.
