摘要： The sheet feeder is formed by a separate unit (10) which can be easily mounted spaced from the platen roller (14) on a typewriter (12) or printer of a data processing system. The print carriers comprise either a continuous web (22) or individual sheets (20). The continuous web is advanced by pin wheels (72) and guided towards the platen roller. The individual sheets (20) which are supported on a feed tray (30) are fed one at a time by means of stripper rollers (40) and passed towards the platten roller (14). The printed sheets are passed into a collector tray (6) by means of collector rollers (54, 56). The pin wheels (72) device and the stripper rollers (40) are rotated selectively from the platen roller by way of a mechanical transmission including a clutch which is actuated by a manual control to connect the pin wheels (72) or the stripper rollers (40) alternatively to the platen roller (14).

摘要： A ballistic type wire printing head comprises a metal front support (11) for guiding the printing wires (23) and supporting a group of actuating electromagnetic units (37, 39, 41) associated with the wires. The armatures (41) of the electromagnetic units are pre-assembled on a disc (40) of plastics material. A rear cover (59) which is also of metal encloses the electromagnetic units and in its interior supports spring spider (58) which co-operates with all the armatures of the electromagnetic units. The electromagnetic units have a common internal, ferromagnetic support (35) from which heat is conducted to the front support (11) and cooling fins (25). In a second embodiment, the printing head also comprises a second group of electromagnetic units associated with another series of printing wires. In that case, an intermediate metal member acts as a cover member for the first group of electromagnetic units and as a support for the second group of electromagnetic units.
