  • Patent number: 4743133
    Abstract: The inked ribbon cartridge comprises an endless ribbon, an elongated housing for the ribbon, a first laterally extending finger at one end of the housing, a longitudinally slidable arm at the other end of the housing carrying a second finger disposed generally parallel to the first finger. A drive wheel is located behind the ribbon and is rotatable for withdrawing ribbon from the front section and is operative to create folds in the used ribbon and to stuff the folds of ribbon between the drive wheel and the ribbon. A fixedly mounted stripper ring encircles the drive wheel and carries a stripper foot to strip the ribbon from the wheel. At the exit port are three aligned support members with the middle support member being over center with respect to the other two. A leaf spring member is located in contact with all three support members. The ribbon passes between one of the support members and the spring.

  • Patent number: 4250513
    Abstract: This invention relates to a linearly adjustable support mechanism in general, and more specifically to an apertured adjustment disc which provides a plurality of incremental linear, vertical adjustments, with no horizontal component, to raise and lower a supported member. This device has particular significance in a printing environment to align an ink or toner applicator member, such as a magnetic ink brush, with respect to a recording head or recording medium to insure that the magnetic brush will be parallel to the surface of the recording head or recording medium, to prevent the occurrence of a print intensity gradient in one instance or apply a uniform coating to the recording member in the other instance.

  • Patent number: 4197797
    Abstract: A modular high speed printing system for printing alphabetic and numerical information upon individual items or documents fed individually or in series through the modules. A feeder module performs accounting functions as to the number of documents processed, provides multiple or single mode document feeding and is adjustable to accommodate different size documents. The system also includes one or more printing modules for printing machine readable repetitive data, machine readable consecutive data, repetitive alphanumeric information and consecutive numeric information. A document receiver module adjustable to different size forms is also provided. The printing modules employ common document drive systems including an adjustable document end stop to permit horizontal placement of the information on the document. Vertical positioning of the information on the document is accomplished by means of adjusting the print mechanisms.
