Definitions

  • This invention relates to a printer in accordance with the preamble of claim 1.
  • Japanese Laid-open Patent Specification No. 38175/82 shown in Fig. 2 relates to a feeding apparatus that can use the continuous form 6 and the cut form 15; however, it fails to provide a linear form feed path because it has a roller platen 20 opposite the printing head 1.
  • the continuous form is fed by a tractor 5 with pins.
  • Guide plates 21 and 22 are used for the cut forms and the continuous forms, resp.
  • the roller platen 20 has been employed in printers for both the continuous and the cut forms because it feeds the print paper along a curved path and change of path can be easily attained.
  • the cut form 23 is of carbon copy type consisting of multiple sheets, for example, of five plies, the radius of each sheet from the center of platen varies with each other to cause slight difference D of feed for the upper and lower sheets, so that it has a problem to cause so-called shingling where the printing positions for the upper and lower sheets are gradually shifted.
  • the insertion of the cut form is prevented by the facts that the pin feed tractor projects a plurality of pins over the continuous form surface, and that there is a paper holding plate over the pins.
  • planar platens do not provide combined feeding means for continuous and cut forms; therefore the object of the present invention is to provide a printer of the aforementioned kind that allows both continuous and cut-forms to be printed without the problems encountered in the prior art.
  • the printer of the invention for both continuous and cut forms can eliminate the problem of displacement of printing because it does not have a roller platen providing a curved feeding path and does not cause shingling when a multiply cut form is used. Instead, a planar platen is used and arranged to provide a linear feeding path.
  • the pin feed tractor is removed from the form feeding path to have a free path for the cut form; at the same time, the drive -transmission is disconnected from the pin feed tractor, so that it is not necessary to dismount the remaining continuous form from the pin feed tractor; productivity of the printing operation is therefore improved.
  • Figure 1 is a perspective view of overall configuration of the invention
  • Fgure 2 is a - schematic view of the prior art
  • a printer shown in Figure 1 comprises a printing head 1, a planar platen 2 that provides an opposite plane to the printing head, feed rollers 3 and 4, and a pin feed tractor for feeding a continuous form.
  • platen 2 need only have a portion which holds the form during printing on a linear path, it may have any cross sectional configuration including a trapezoid, a rectangular and a circle with subtense.
  • the rollers 3 and 4 feed the form by holding it between their upper and lower rollers.
  • the roller 4 is for feeding the leading edge of print paper toward the platen 2, and may be eliminated.
  • the pin feed tractor 5 has a series of pins 5a engaging with feed perforation of the continuous form, a paper holding plate 5b, and a hinge 5c mounting the paper holding plate on the pin feed tractor body in such a manner that the plate is permitted to be freely opened or closed.
  • the series of pins 5a are driven by a gear 7, which is in turn engaged with a gear 8 that is driven by a motor 10 through a toothed belt 9.
  • Figure 4 is a side efevational view of a state feeding the continuous form that is perspectively shown in Figure 1.
  • the pin feed tractor 5 feeds the continuous form 6 linearly along the form feed tine connecting the upper surface of the platen 2 and the holding point of the feed roll 3. Because the path of the continuous form 6 shown in Figure 4 is inclined by about 45°, it is convenient for observation of printing condition, or insertion or removal of a cut form.
  • the inclination may be set at any angle from 0° to 90° if required.
  • a cut form 15 is inserted from the upper right portion of Figure 5. At that moment, the lower end 15a of the cut form 15 slides over the paper holding plate 5b of the pin feed tractor 15 and the continuous form left thereon to maintain a substantially linear feeding path. If there is no continuous form 6, the lower end 15a of the cut form 15 slides over the paper holding plate 15a and an intermediate guide plate 16 to maintain a substantially linear feeding path.
  • the cut form 15 may be inserted from the lower left portion to the upper right portion with inclination in the figure.
