摘要： An ink ribbon feeder having a pair of rotatable ratchet wheels for driving ribbon spools. A control member rockable toward either ratchet wheel carries a ratchet wheel drive member movable on the control member for driving a respective one of the ratchet wheels to which the control member has been rocked. When ribbon from a spool has run out so that ribbon tension prevents further driving of a particular ratchet wheel, the control member rocks toward the other ratchet wheel to bring the ratchet wheel drive member into position to drive the other ratchet wheel and feed the ribbon in a reverse direction.

摘要： A molded one-piece wire guide which aligns the free ends of a plurality of reciprocating print wires in a given vertical plane which extend from a set of solenoid assemblies disposed in the transverse array. The wire guide comprises first guides which constrain the individual wire so as to suppress a movement thereof in a direction transverse to the reciprocating movement of the print wires, and second guides which constrain the individual wires to suppress a vertical movement thereof.

摘要： A wire printer comprises a platen which guides a record medium, a carriage supported for reciprocable movement parallel to the platen, and a print head assembly carried by the carriage and including a plurality of print wires. The head assembly includes a plurality of print wires. The head assembly includes a plurality of solenoids, each of which is connected with one end of an associated print wire, the other end of which is disposed adjacent to the platen with a small clearance therebetween. The other end of each print wire is provided with a portion which is aligned with each other on a common vertical plane. The print head assembly is pivotally connected with the carriage and is guided to undergo a composite motion including an angular and a radial motion such that as the carriage is moved, a given point on the extension of the linear portion of the print wire moves along an imaginary centerline which passes through the center of stroke of the carriage and which is at right angles to the platen. The linear portion of the print wire has an offset angle from the platen which increases with an increase in the distance from the centerline. The maximum offset angle is chosen to be compatible with the practical printing operation.
