Definitions

  • a hammer having a face formed of a convex surface is mounted so as to engage the platen and deflect it in a direction which results in the movement of the convex face of the hammer over the face of the platen to produce a rubbing action which transfers the printing material from the ribbon to the record material.
  • This invention is directed to a printing mechanism for printing color bars on a tag for use in semi-automatic, mark-sensing systems for check-out counter applications in supenmarkets' and retail department stores, credit card and inventory control applications, and the like.
  • the tag may be attached to an item to be sold, for example, and then read, during the sale thereof, by a hand-held, optical probe scanner, which is scribed, or glided, across the tag.
  • An example of an optical probe scanner is found in U.S. Pat. No. 3,238,501, issued Mar. 1, 1966, on the application of Stephen M. F. Mak et al.
  • a printing mechanism for applying ink to a record member which includes a spring-mounted platen member and a hammer member having a type face composed of a convex surface.
  • the hammer is so mounted that, as it travels through its path of movement, it will strike and deflect the platen in such a manner that the convex face of the hammer will move across the face of the platen, thereby producing a rubbing action which is sufficient to transfer the ink from a printing ribbon to a record member.
  • FIG. 1 is a plan view of a color-coded record tag showing the arrangement of the various color bars which are utilized to store data on the tag.
  • FIG. 2 is a partial side view of the printing hammer and the platen, showing the hammer at the initial contact with the platen.
  • FIG. 3 is a view similar to FIG. 2 except that the hammer is shown at the bottom of its printing stroke
  • the present invention is directed to a printing mechanism for printing data in the form of color bars on a tag or label.
  • the data-encoded tag member 16 (FIG. 1) consists of a plurality of contiguous color bars, each color bar being one color of three or more colors and of a color difierent from the color of its neighboring color bars.
  • the colors that are employed in the tag 16 are green 17, black 18, and white l9.
  • the green and black color bars are printed over a white background, so that the white color bars are defined by areas where no green or black colored bars are printed.
  • FIG. 2 there is shown a partial side view of the printing mechanism, including a hammer 20 and a platen 21, which comprises the end portion of a cantilever leaf spring 22, which is mounted to a support member 23 by a screw 24.
  • the tag member 25 and a printing ribbon 26 are positioned between the hammer and the platen. Both the tag member 25 and the printing ribbon 26 move in a direction perpendicular to the plane of rotation of the hammer 20.
  • the support member as shown in FIG. 2, is mounted at an angle so as to provide a pre-load force between the platen 21 and the hammer 20 and also to insure that the face of the platen is in a horizontal plane.
  • the hammer 20 is pivoted about a shaft 27, which is mounted parallel to the direction of travel of the tag members. The movement of the hammer during a printing stroke follows a circular arc.
  • the face 28 of the hammer 20 is formed of a circular arc which provides a convex surface.
  • the face of the hammer forms the bar type which is printed in one of the colors on the tag member 16 (FIG. 1).
  • Another printing mechanism will print the bars in the second color.
  • the face 28 of the hammer 20 will initially contact the tag 25, the printing ribbon 26, and the platen 21 at one of its ends as shown in FIG. 2.
  • the hammer moves through its printing stroke, it follows a circular are which deflects the platen 21.
  • the deflection of the platen allows the convex face 28 of the hammer to move across the face of the platen, which produces a rubbing or shearing action between the hammer and the platen.
  • the cantilever leaf spring 22 (FIG. 2) was designed to give a deflection curve which would have a slope equal to the slope of the convex surface 28 of the hammer at the final contact point of the face, as shown in solid lines in FIG. 3. Due to the curvature of the hammer face 28 and the deflection of the spring platen 21, the point of contact between the two moves across the hammer face during the print stroke, so that, at the end of the stroke, the point of contact is at the other end of the hammer. In this way, the entire bar is printed. This point of contact between the hammer and the platen produces a high printing pressure sufficient to transfer the ink from the ribbon up to the tag with a relatively low hammer force.
  • Rubber dampers may be mounted below the spring platen 21 to support the platen against the action of the hammer in order to dampen any vibration which the platen might have due to the action of the hammer.
  • the color bars are printed on the tag in a manner which is relatively simple in its construction and also in its operation.
  • a hammer member comprising an elongated body portion pivotedly mounted at one end and having a portion offset in a generally perpendicular direction to said body portion at the other end, said offset portion having an end portion comprising a convex printing surface, said hammer member adapted for rotational movement during each printing operation;
  • said support member comprising an elongated resilient member fixedly mounted at one end and having a free flat surface portion at its opposite end which end extends in a direction towards the pivoted end of said hammer member where the flat surface portion is juxtaposed with the convex printing surface for supporting a record member and an ink carrier in a blocking position with the movement of said convex surface, said support member mounted to position the record member and the ink carrier into engagement with the convex printing surface and in a plane parallel with the longitudinal axis of the elongated body portion of said hammer member whereby upon rotation of said hammer member during a printing operation, the flat surface portion of said support member is deflected by movement of said convex surface sufficiently to allow the convex surface to move across the ink carrier, thereby transferring ink from the carrier to the record member.
  • a printing apparatus comprising a. a hammer member consisting of an elongated body portion pivotally mounted at one of its ends for rotational movement and having a right-angle portion at the opposite end, said right-angle portion having an end portion in the form of a convex printing surface, said hammer member adapted to be rotated about its pivoted end during each printing operation to move the convex printing surface in a printing direction;
  • a platen mounted adjacent the convex surface of said hammer member, said platen comprising the free end portion of a cantilever leaf spring the other end of which is fixedly mounted, said free end portion extending in a direction towards the plane of the axis 0 rotation of said hammer member and in a juxtaposition with said convex surface normally blocking the printing movement of said surface, said leaf spring mounted to position the platen into engagement with one end of said convex surface and in a plane parallel with said elongated body;
