Abstract
PRINTER
Abstract To provide a virtually common linear path to, and through the printing station of a printer in which pin-feed tractor-driven continuous paper and cut-sheet paper are to be accommodated, the tractor drive is pivotable out of its normal feeding position, thus making room for a cut-sheet feed along substantially the same linear path as that followed by the tractor-driven continuous paper.

Detailed Description of the Invention:
Background of the Invention This invention relates to a printer that can use both long print paper with perforations for feed on its side edges (so-called continuous form) and short print paper without perforation (so-called cut form).
The printer is characterized in its relation to a form feed path with a platen and its construction in which a continuous form feeding means can be evacuated.

38175/82 relates to a feeding apparatus that can use the continuous form and the cut form, it fails to provide a linear form feed path because it has a roller platen.
Although a planar platen is known, there is no such one that relates a continuous form feeding means with a cut form feeding means as in this invention.
!
Problems to Be Solved by the Invention The roller platen 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. However, if the cut form is of carbon copy type consisting of multiple sheets, for example, of five plies, the radius of -1~5~ 7 each sheet from the center of platen varies with each other to cause slight difference of feed for the upper and lower sheets, so that it has a problem to cause so-called shingling where the printing po-sitions for the upper and lower sheets are gradually shifted (Figure 3).
On the other hand, when the feeding path for the cut form is overlapped with that for the continuous form by using the planar platen, there is such problem that the feeding means for the continuous form (pin feed tractor~ becomes an obstacle when the cut form is inserted.
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.
The subject of the invention is to solve simulta-neously both of the above-mentioned problems.
~ZS~Z~7 Means for Solving the Problems (Figure 1) The shingling should be eliminated if the form feed path in a prin-ting station consisting of a printing head and a platen is arranged to be linear. Thus, as the platen, a planar type that provides a linear feeding path is employed in place of a roller type.
Another problem caused by this that prevent the cut form from insertion because of overlapping of feeding paths for the continuous and cut forms is solved by evacuating the pin feed tractor at least at end portions near the platen from the form feeding path A-A. It may be allowed to evacuate entire pin feed tractor.
Embodiment of the Invention (Figures 1, 4 and 5) 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.

Since the platen 2 is sufficient to be one of which portion holding the form during printing provides a linear path, it may have any cross sectional config-uration 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 engag-ing 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 elevational view of a state feed-ing the continuous form that is perspectively shown in Figure 1. The pin feed tractor 5 feeds linearly the continuous form 6 along the form feed line con-necting the upper surface of the platen 2 and the holding point of the feed roll 3. secause the path of the continuous form 6 shown in Figure 4 is in-clined 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.
Now, it is assumed that it is required to switch the paper to the cut form. Although it is not required to remove the continuous form being used from the pin feed tractor 5, it is required to cut or reversely feed the continuous form so that its remaining por-tion does not protrude from the end of pin feed trac-tor near the platen (see 6a in Figure 5). Then, when a lever 12 is rotated clockwise (in Figure l) around a pivot 13 by a cam 11 (or any other means such as an JA9~85-005

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.
The subject of the invention is to solve simulta-neously both of the above-mentioned problems.

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 elevational view of a state feed-ing the continuous form that is perspectively shown in Figure 1. The pin feed tractor 5 feeds linearly the continuous form 6 along the form feed line con-necting the upper surface of the platen 2 and the holding point of the feed roll 3. secause the path of the continuous form 6 shown in Figure 4 is in-clined 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.
Now, it is assumed that it is required to switch the paper to the cut form. Although it is not required to remove the continuous form being used from the pin feed tractor 5, it is required to cut or reversely feed the continuous form so that its remaining por-tion does not protrude from the end of pin feed trac-tor near the platen (see 6a in Figure 5). Then, when a lever 12 is rotated clockwise (in Figure l) around a pivot 13 by a cam 11 (or any other means such as an JA9~85-005
2~7 electromagnet), the end of pin feed tractor 5 near the platen 2 is rotated clockwise around a shaft 14 and evacuated under the form feed plane A-A. At that moment, the gear 7 is disengaged from the gear 8.
Therefore, there arises no trouble even if the remaining continuous form on the pin feed tractor is not removed. 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.
24~7 Operation is described when the continuous form is used again. When the lever 12 is rotated counter-clockwise by the cam 11, the pin feed tractor 5 re-turns on the form feeding path. At that moment, the gear 7 engages with the gear 8 to complete the drive transmission relation. At that moment, if good meshing between the gears is not obtained because their teeth abut with each other, it is sufficient to slightly vibrate the gear 8 clockwise and counter-clockwise by supplying control signals for a moment to normally and reversely rotate the motor 10.
Effects o:f the Invent.ion The printer of the invention that can use both the 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 not cause the shingling when a multiply cut form is used.
Evacuating the pin feed tractor from the form feeding :~2513Z~'7 path solves the problem of prevention of the cut form, and disconnects automatically the drive trans-mission relation to the pin feed tractor, so that necessity to remove the remaining continuous form from the pin feed tractor. This allows to omit an operation to mount or dismount the continuous form to or from the pin feed tractor when the form is switched, so that the productivity of printing opera-t.ion is irnproved.

Therefore, there arises no trouble even if the remaining continuous form on the pin feed tractor is not removed. 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.
24~7 Operation is described when the continuous form is used again. When the lever 12 is rotated counter-clockwise by the cam 11, the pin feed tractor 5 re-turns on the form feeding path. At that moment, the gear 7 engages with the gear 8 to complete the drive transmission relation. At that moment, if good meshing between the gears is not obtained because their teeth abut with each other, it is sufficient to slightly vibrate the gear 8 clockwise and counter-clockwise by supplying control signals for a moment to normally and reversely rotate the motor 10.
