Abstract
A high-speed printer includes a standard printing element, such as a daisy wheel, a paper feed mechanism and a ribbon feed mechanism. All of these various devices are controlled by a single linear actuator which comprises an elongated cylindrical magnet, C-shaped in cross-section, through which a ferrous core axially extends. A plurality of separate armatures envelope the core in the air gap between the magnet and core and are adapted to move linearly upon application thereto of a control current. The armatures control, respectively, the movement of the carriage containing the printer element, the rotation of the printer element, the advancement of the paper feed mechanism and the incremental positioning in both directions of the ink ribbon.
