Abstract
A teleprinter includes a carriage for conveying a dot matrix-type print head along an operating path parallel to a print-receiving surface. The carriage is mounted on parallel-spaced support rods by means of spaced bearings slidably engaged to one of the support rods, and a pair of perpendicularly-aligned guide rollers which engage the other guide rod. The carriage is advanced by a drive belt which extends along the carriage operating path and is attached to the carriage at either end. A stepper motor coupled to one of the pulleys drives the belt to position the carriage. A removable cartridge on the carriage contains an inked ribbon which is advanced with movement of the carriage by a drive gear engaged to the drive belt. A unidirectional clutch prevents the inked ribbon from moving in a reverse direction during carriage return.
