ABSTRACT:
Character belt apparatus for use on a line printer and including a thin, flexible metal belt formed into an endless band for carrying replaceable character slugs affixed thereto at regular intervals. Each character slug has a front side on which an alphanumeric character is provided and a rear side which is recessed in a particular manner so as to mate with a mounting and fastening element that is itself affixed to the belt by spot welding or the like. Although the fastening mechanism of the element may vary from embodiment to embodiment, in each case the matingly engaging surfaces of the element and slug provide for accurate positioning of the slug relative to the belt in both the longitudinal and transverse belt directions. In one embodiment a screw is used to fasten the slug in registration with a nut type element plate. In second and third embodiments, spring clip type elements mount and affix specially adapted character slugs to the belt.
