Definitions

  • the print opening of a card holder is configured to have unidirectionally angled upper and outer edges that progressively cam the edges of a sheet into engagement with a platen without catching the corner of the sheet or otherwise jamming the paper feed opera tion.
  • FIG. 1 A first figure.
  • Printers such as typewriters typically include a device positioned adjacent the printing point termed a card holder whose function it is to hold a writing sheet against a support platen. This function is particularly important where relatively stiff card stock is being typed upon which otherwise would not follow the contour of the platen.
  • a card holder made of clear plastic material has been found to be particularly convenient since it does not in terfere with the operators view of typed material. Furthermore, useful scales can be directly imprinted upon the clear plastic material in a particularly convenient manner.
  • the plastic card holder may be made to completely surround the printing point thereby providing an opening through which print impact occurs.
  • a plastic card holder of this configuration serves its function well but requires the printing point to be positioned over a central portion of a writing sheet being inserted into the typewriter. Where the printing point is positioned adjacent to the left margin of the sheet being inserted, the print opening in the card holder has a serious tendency to trap the corner of the sheet. Where lightweight sheet material is being inserted, this trapping may cause the corner to fold and the sheet to be spoiled. Heavier card stock, when trapped, may actually jam the feed operation. Alternatively, where easily replaceable snap-in card holders are employed, trapping of heavy card stock may cause ejection of the card holder from its support.
  • the leftward or outer edge of the print opening is likewise inclined outwardly so as to engage but a single point on the left edge ofa sheet. This engagement point moves progressively toward the corner of the sheet as the printing point moves rightwardly to prevent jamming.
  • FIG. 1 is a fragmentary perspective view of a portion of a typewriter having a card holder constructed in accordance with the prior art.
  • FIG. 2 is a fragmentary perspective view of a portion of a typewriter similar to that shown in FIG. 1 but employing an improved card holder constructed in accordance with my invention.
  • FIG. 3 is a front elevational view of the card holder and typewriter platen shown in FIG. 2, and
  • FIG. 4 is a side cross-sectional view of the card holder and platen shown in FIG. 3 taken along line IV-IV thereof.
  • FIG. 1 a typewriter or printer 10 is shown having a print forming type element 11 supported by a carrier 12 adjacent an elongated circular cylindrical paper sheet support platen 13.
  • Type element 11 and platen 13 defines a printing point 14 therebetween.
  • Carrier 12 is in turn supported on a laterally extending shaft 15 for movement horizontally with respect to the platen 13 thereby displacing the printing point 14 along a writing line 16.
  • a paper deflector plate 30 is carried beneath platen 13 and includes idler pressure rolls 31 for gripping a sheet of paper or other writing material 20 against the platen 13.
  • the platen 13 is rotatably mounted by bearings 32 in frame side plates 33. Knobs 34 at either end of the platen l3 enables it to be rotated to move sheet 20 in a paper feed direction 35 during paper insertion.
  • a prior art type card holder 40 is supported adjacent the printing point 14 by a support bracket 17 that in turn is carried by a mounting plate 18 on the carrier 12.
  • Card holder 40 includes an inverted U-shaped print opening 41 through which print element 11 impacts sheet 20.
  • the card holder 40 is curved or otherwise configured to wrap the sheet 20 about platen l3 and into close adjacency therewith particularly at the printing point 14.
  • a paper bail 36 carrying rollers 37 thereon further assists in holding the sheet material 20 around the platen 13.
  • the prior art card holder 40 will satisfactorily receive a sheet 20 that is rolled to its printing position with print point 14 positioned over a mid portion of the sheet 20.
  • a failure can occur as shown in FIG. 1 where the corner 21 of sheet 20 is aligned with part of the print opening 41 during initial roll in.
  • the corner 21 of the sheet 20 being unrestrained, projects through the print opening 41 and ultimately becomes trapped as shown in FIG. 1.
  • corner 21 will fold over forming a dog car and the sheet 20 may be spoiled.
  • the feed will simply jam requiring the operator to roll back the platen 13, move the print point 14 to the right, and reroll the platen 13 to the starting position.
  • a similar entrapment of the corner 21 can occur if typing is to be done very close to the upper left-hand edge 22 of the sheet 20. In this event, the unrestrained corner 21 becomes trapped as shown in FIG. 1 as the carrier 12 moves rightwardly with letter feeding movement.
  • a card holder 50 constructed in accordance with my invention has a print opening 51 partially defined by camming edges 52 and 53 that are configured to engage the edges 22 and 23 of sheet 20 progressively and thereby move the sheet 20 into close adjacency with the platen 13 without trapping the sheet corner 21 as in the case of the prior art card holder 40 described in FIG. 1. More specifically, the card holder 50 shown in FIGS.
  • FIG. 2 and 3 constructed of a transparent plastic plate-like body comprising a pair of side portions 54 and 55 which extend upwardly in the paper feed direction 35 and define respectively side edges 53 and 56 of the print opening 51. These side edges 53 and 56 are separated by a spacing 57 that spans the print point 14.
  • An upper bridging portion 58 of the card holder 50 interconnects the side portions 54 and 55 and defines the upper edge 52 of the print opening 51.
  • upper edge 52 of the card holder 50 is unidirectionally angled upwardly and to the left throughout the entire spacing 57.
  • the longer side edge 53 is angled slightly upwardly and laterally outwardly with respect to the printing point 14.
  • edge 52 functions to limit engagement of the edges 23,52 to a single point for example, point 24 on the sheet leading edge 23 as the sheet is moved in the paper feed direction 35.
  • the angle of edge 53 functions similarily upon letter feed movement of print point 14 rightwardly along writing line 16.
  • the point of sheet edge engagement between the edge 52 or 53 of the card holder opening 51 moves toward the corner 21 of the sheet 20 and progressively displaces the corner 21 inwardly toward the platen 13 where it cannot be trapped as shown in FIG. 1.
  • the crosssection of the upper camming edge 52 is tapered to provide a camming surface 59 best shown in FIG. 4 thereby avoiding an abrupt ledge that might otherwise serve as a trapping surface for the corner 21 of the sheet 20.
  • left edge 53 is similarly tapered.
  • the operator need not be concerned with the relative location of the left corner of a page with respect to the typewriter printing point.
  • the sheet leading edge 23 will be progressively engaged by the edge portion 52 until the corner 21 is guided beneath the upper bridging portion 58.
  • a printer including print forming mechanism, and a writing sheet support platen, said print forming mechanism and said platen defining a printing point and writing line therebetween, means for feeding a writing sheet into operative interposition between said print forming mechanism and said platen in a paper feed direction that is normal to said writing line, and means for holding the writing sheet against said platen at said printing point
  • a plate-like body means supporting said plate-like body adjacent said platen at said printing point, said plate-like body comprising a pair of side portions that extend in said paper feed direction and are spaced laterally on opposite sides of said printing point, and an upper bridging portion positioned above said printing point and interconnecting said side portions, said side and upper bridging portions thereby respectively defining side and upper edges of an open portion through which said print forming mechanism is enabled to have print cooperation with the writing sheet supported by said platen, said platelike body being configured to urge the writing sheet into close adjacency with said platen at said printing point; wherein the improvement comprises:
  • said upper bridging portion of said plate-like body defining an upper camming edge of said open portion that extends transverse to said paper feed direction at a unidirectional angle other than substantially throughout the entire space between said side portions.
  • a printer as defined in claim 1 wherein said printing sheet support platen comprises an elongated circular cylindrical member that is rotatably mounted to provide said writing sheet feeding means.
