Abstract
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.
