Abstract

A high speed matrix printer has a mechanical drive unit for the printing head carriage comprising an endless belt drive (61) passing around two belt pulleys (60, 62) and supporting the carriage (41). One of the pulleys serves as a drive pulley which is powered by a motor (46) attached to a base plate (23). The drive shaft (48) of the motor powers a vertically running shaft (51) via worm gearing whereby a gear wheel at the top of this shaft drives a gear wheel (56) on the shaft of the drive pulley (60). A drive pin (65) is fixed to the belt and moves within an open ended slit in the carriage. The slit lies parallel to the plane of the belt pulleys and at right angles to the length of the two belt strings.
