Definitions

  • ABSTRACT Disclosed is an imprinter for printing upon documents from a printing plate, the imprinter utilizing a compensating roller platen.
  • the platen may be of the dry roll-type and includes a plastic or nylon outer sleeve of typically to durometer hardness, Shore D" scale.
  • An inner sleeve is also provided, the inner sleeve being rotatably mounted with respect to the imprinter carriage. This sleeve has a peripheral grooved portion disposed along a substantial portion of the length thereof.
  • the inner sleeve is also of 80 to 90 durometer hardness, Shore 0" scale.
  • an intermediate, annular, cylindrical resilient member Disposed between the inner and outer sleeves is an intermediate, annular, cylindrical resilient member which has a Shore "D" scale hardness of typically 40 to 45 durometer and which may be may be made of rubber. Because of the groove on the inner sleeve, the resilient intermediate member has room in which to retract whenever the combined thickness of the printing plate and the document encountered by the roller platen is greater than that for which the imprinter was originally set. Thus, a wide range of printing plate and document thicknesses may be accommodated.
  • This invention relates to imprinters and in particular to imprinters of the type which compensate for varying thicknesses of printing plates and/or documents used therewith. Further, in particular, this invention relates to an improved compensating roller platen.
  • a particular frequent and troublesome problem relating to the imprinting of documents is smudging. 'lhis quite often causes the character reader to make errors thereby decreasing document throughput. Smudging, in turn, is generally caused by excessive printing pressure. Usually, excessive printing pressure occurs whenever the combined thickness of the printing plate or credit card and of the documents encountered by the roller platen is greater than that for which the imprinter was originally set. Since, in practice, a wide range of card thicknesses are encountered because certain cards are used more than others, the problem of smudging is quite widespread and severe.
  • the varying card and/or document thicknesses encountered in practice cause the print density of the printed characters to vary from very light to very heavy, thereby further restricting the capability of the character readers to efficiently and accurately read the printed matter.
  • FIG. I is a perspective view of an imprinter utilizing the compensating roller platen of this invention.
  • FIG. 2 is an end view of an illustrative embodiment of a roller platen in accordance with the invention.
  • FIG. 3 is a cross-sectional view taken on the line 3-3 of FIG. 2.
  • FIG. I there is shown a perspective view of an imprinter utilizing the improved roller platen of the invention.
  • the imprinter comprises a base It) upon the upper surface of which is disposed a print bed 12.
  • a printing plate 14 such as a credit card.
  • a document [6 Disposed over the plate [4 is a document [6 upon which is printed any information embossed or raised from the plate 14 in a wellknown manner.
  • the document I6 is a sales invoice and imprinted upon the document is a customers name and account number such as indicated at 17.
  • I may also include digit wheels which may be set by the operator to provide the printing of variable information upon the document I6.
  • digit wheels which may be set by the operator to provide the printing of variable information upon the document I6.
  • Respectively disposed within the two long sides of base 10 are a pair of lengthwise slots, one of which is indicated at 18 and the other of which is not shown in FIG. I.
  • Mounted for longitudinal movement along the slots is a carriage 20 which contains a roller platen 22 which may be of the inked or dry roll-type.
  • a shaft extends between the vertical legs 24 and 26 of carriage 20, the platen 22 being mounted upon the shaft for rolling movement whenever the platen engages a document placed upon the print bed 12.
  • the manner of mounting the roller platen and its associates shaft is a matter of design and many means for doing this are well known to those of ordinary skill in the art.
  • FIGS. 2 and 3 respectively show an end view and a cross-sectional view of an illustrative embodiment of a roller platen in accordance with this invention.
  • the roller platen comprises an outer sleeve 28, which is typically made of nylon and which has a typical hardness of to durometer, Shore "D" scale. All hardness values hereinafter are in the Shore "D” scale.
  • the outer sleeve 28 may be ink porous rather than of the dry roll-type.
  • the roller platen also includes an inner sleeve or shaft 30 which, as best seen in FIG. 3, has a peripheral, grooved portion 32 which extends entirely around shaft 30 and along a substantial portion of the length thereof but less than the length of the roller platen. Further, the length of grooved portion 32 is greater than the height of print field of the printing plate, which in FIG. I, for example, would extend from the bottom of the NUMBER indicated at I7 to the top of the NAME also indicated thereat. Thus, the print field constitutes that area of the printing plate 14 containing the information to be printed. As will become more apparent hereinafter, the importance of the peripheral grooved portion is paramount and its presence brings about the desired results claimed for this invention.
  • a journal opening 34 extends through the sleeve 30 which is adapted for rotatable mounting upon the shaft (not shown, but discussed hereinbefore) which extends between the vertical legs 24 and 26 of the carriage 20.
  • the opening 34 is optional and other means for rotatably mounting the sleeve 30 with respect to the carriage 20 may be provided.
  • the inner sleeve 30 is also typically made of nylon and has a typical hardness of 80 to 90 durometer.
  • annular, cylindrical member 36 Disposed between the inner and outer sleeves 28 and 30 is an annular, cylindrical member 36 which is typically made of rubber and which has a typical hardness of 40 to 45 durometer.
  • the distance between the outer peripheral edge of outer sleeve 28 and the print bed will vary in accordance with the combined thickness of the particular printing plate 14 and document I6 disposed upon the print bed l2 of the imprinter of FIG. I.
  • the compensating roller platen 22 will permit the resilient member 36 to withdraw or retract into the peripheral grooved portion 32 to thereby retract the platen from the print bed whenever the thickness is less than that for which the imprinter was originally set.
  • the resilient member 36 is shown as being of solid construction, a plurality of annular, resilient members may be disposed coaxially between the sleeves 28 and 30. In such a case, a plurality of peripheral, grooved portions would extend along the length of sleeve 30 and would be respectively disposed adjacent the plurality of annular, resilient members to thereby permit the resilient members to retract into the plurality of grooved portions.
  • the resilient members might be rings or the like.
  • the length of the groove 32 with respect to the overall length of the inner sleeve 30 can be adjusted to meet the do mands of the particular situation. The only requirement is that the length thereof be sufficient to permit enough retraction of the resilient member 36 so as to insure effective compensating action.
  • the outer diameter of the outer sleeve 28 may be l inch; the outer diameter of the annular member 36 may be seven-eighths inch; the outer diameter of the nongrooved portion of the inner sleeve 30 may be three-eighths inch; the diameter ofjoumal hole 34 may be one-fourth inch; the depth of the grooved portion 32 may be one thirty-seconds inch; the overall length of the sleeve 30 may be 1 l/l6 inches; and the distance between the outer end of sleeve 30 and the outer end of groove 32, one-eighth inch.
  • a compensating roller platen for use with apparatus for imprinting a document with information from raised characters on a printing plate comprising an outer sleeve;
  • an inner shaft having a peripheral grooved portion extending entirely around said shaft. said grooved portion extending axially for a distance greater than the height of the print field of the printing plate but less than the length of the roller platen;
  • an intermediate, annular member disposed between said inner shaft and outer sleeve, the resiliency of said intermediate member being l) substantially greater than that of said inner shaft to permit said intermediate member to retract within said grooved portion of the inner shaft and (2) substantially greater than that of said outer sleeve, the resiliency of said outer sleeve being substantially the same as or greater than that of said inner shaft, said roller platen being dimensioned such that the portion of said intermediate, annular member which overlies said grooved portion is depressed into said grooved portion whenever the combined printing plate and document thickness encountered by said roller platen is greater than that which the imprinting apparatus is normally used with, said grooved portion thereby compensating for combined printing plate and document thicknesses greater than normally encountered to minimize undesired background smudging and provide sharp contrast of the printed information.
