Description

[Detailed Description of the Invention] Various types of continuous copy forms can be used on typewriters, tabulators,
It is supplied to the printing device of office machines such as minicomputers and used for printing.

These continuous copying forms are a copying form in which a carbon transfer sheet is inserted and overlapped and copies are made by carbon transfer, or a copying form is made by a chemical reaction in which a dye-containing microcapsule is placed on the back side of the form and a royal coloring agent is placed on the front side. It is a carbonless copy form that forms an image. Typical continuous copying forms, as also shown in US Pat. No. 2,907,585 and British Patent No. 1,376,447, have rows of form feeding holes on both sides. Many serial copy forms are intended to be used in office computer printers and terminal printers, and to be removed from the printer after several sets of prints and ready for immediate use. When these machine copy forms are printed using a normal computer printing device, the supply holes on both sides of the form are engaged with the supply pins of a pair of traction pin feeding devices set above the printing section of the printing device. Ru. The traction device is therefore actuated and the stationary continuous copy form is advanced into the printing device. Therefore, after printing a predetermined amount on a unit copy form of a subsequent form, if the printed unit copy form is separated from the continuous state and removed from the printing device, printing is performed again.
Each time, it is necessary to load the supply hole of the most advanced unit copy form into the supply pin of the supply device located in front of the printing device, so the copy form at the leading edge of the continuous copy form is
It is a piece of paper that cannot be printed. For this reason, the unprinted copy form at the leading edge of the continuous copy form is discarded and is wasted. Therefore, in the present invention, a printed copy form can be taken out while the continuous copy form is set in the printing device of an office machine, and even after being taken out, the continuous copy form is maintained by the green feeding bands on both sides. To obtain a continuous copying form having an improved structure that can maintain engagement with a supply pin and thereby eliminating the wastage of copying forms since no copying form is produced without printing. It is.

The continuous copying form of the present invention has a plurality of webs superposed one on top of the other, along at least one side edge an intermediate web joined to each other, and a row of feed holes on both sides for engagement with a feed device of an office machine. The continuous copy document is advanced through the printing device by means of an outer web having an upper web and a lower web. The outer webs, the upper web, the lower web, and the intermediate web, are bonded to each other and to only one of the outer webs. One of the outer webs is removable from the other outer web together with the intermediate web, so that when the glued intermediate web is separated from the serial copy document along with one of the outer webs, the outer web of the serial copy document The grooves on the other and both side edges are left to form a drive web for starting printing by the printing device.
Embodiments of the invention will now be described in detail with reference to the accompanying drawings. In the drawings, like reference numerals refer to the same or corresponding parts, and the continuous copy form is designated by the reference numeral 10 in FIGS. It has a web 11 and a lower web 12.

As shown in the figure, the rows of spaced-apart holes 13 are provided in the upper web 11 and the lower web 12 along both side edges in alignment with each other. Longitudinal adhesive parts 15 (first adhesive parts) and 16
A second bonding section (second bonding section) is provided inwardly of the row of aperture holes for attaching the upper and lower webs 12 to each other at this side edge. A longitudinal perforation line 17 (first weakened line) is provided only in the upper wip 11, slightly inward of the adhesive portion 15. Also, the upper web 11 has a cutout line 1 located slightly inward of the adhesive portion 16.
There is a longitudinal cut along 8 (second weakened line). If the adhesive part 14 is provided further outside the supply hole of the supply V feed belt 33, the strength of the supply belt will be increased and feeding can be performed smoothly. Bonded portion 15 of lower web 12
, 16 are provided with perforation lines 17a, 18a.
The perforation lines 17 and 18 of the upper web 11 have a longer length than the perforation lines 17a and 18a of the lower web 12, so that they can be easily cut. Carbon transfer sheet 21
When combining them to form a copy document, the plurality of intermediate webs 19 are stacked between the upper web 11 and the lower web 12 together with carbon transfer sheets 21 placed on both sides of the intermediate web.

As shown, the intermediate web 19 is connected to the carbon transfer sheet 2.
1 and near the perforation line 17.
Further, the intermediate web is attached to the upper web 11 via the overlapping carbon transfer sheets 21. For example, the carbon transfer sheet 21 is attached to the web by overlapping it with the adhesive part 22 of the third adhesive part. Then, the carbon transfer sheet 21 is attached only to the intermediate web below the adhesive part 23 that is slightly spaced apart from the adhesive part 22 of the third adhesive part. In the above-mentioned embodiment, a continuous copying form with a carbon copying structure in which a carbon transfer sheet 21 was interposed was described, but a continuous copy form without using a carbon transfer sheet 21 was described.
A continuous copying form employing a carbonless copying system in which dye-containing microcapsules are applied to the back surfaces of an upper web 11 and an intermediate web 19, and a main coloring agent is applied to the surfaces of an intermediate web 19 and a lower web 12 to perform copy entry. In this case, since the carbon transfer sheet 21 is not present, the intermediate web 19 is placed at the position of the adhesive part 22 of the third adhesive part.
is connected to the upper web 11.

The carbon transfer sheet 21 has many diagonal cuts 24, and the cuts 24 are provided between the adhesive parts 22 and 23.

This cut 24 is covered by U.S. Patent No. 2907585.
Similarly to No. 3, this is provided between the adhesive part 22 and the adhesive part 23 of the third adhesive part, so that the carbon transfer sheet 21 and the upper web 11 and the intermediate web 19 can be fixed by adhesion at the cut 24. When the continuously copied form passes over the circumference of the supply cylinder or platen cylinder, etc., the gap 24 occurs between the upper and lower forms, which causes wrinkles on the paper. Continuously copied forms can be fed accurately and easily because they can be transferred smoothly without any problems, and any misalignment can be naturally adjusted to the original state after passing through the cylinder. Each of the upper web 11 and the intermediate web 19 has a longitudinal cutout line 25 slightly inward of the adhesive portion 22.
is provided.

Further, the horizontal cutout lines 26 are provided at the same position on each web at predetermined intervals for each unit copy form of the continuous copy form, so that the upper web 11 through which the copy form passes after passing through the printing device.
can be removed together with the intermediate web 19 from the lower web 12. The adhesives 22, 23 of the embodiment may be replaced by an attachment in which paper staples are used, as shown in GB 1,676,447.

Next, the use of the continuous copy form of the present invention will be explained.

The continuous copy form of the present invention is one in which information is printed by a terminal printing machine, and the copy form on which predetermined information is printed is
As shown in FIG. 3, with the terminal printing machine loaded, the upper web 11 and the intermediate web 19 are cut out along the perforation line! 7, 18 and the transverse cut-off hole line 26, the lower web 12 and the feed strips 33 on both sides remain on the printing machine, and are separated from the continuous copy form, and the cut copy In order to print on the copy form located next to the form, the continuous copy form is printed as it is, and the feed is also sequentially printed, and after printing, it is separated from the continuous copy form and used as described above.

After the upper web 11 and the intermediate web 19 have been removed, the lower web 12 is cut out from the perforation lines 17a, 18b and the transverse perforation line 26 when necessary, and the supply band 33 is removed to form a unit web. It is. To separate the web of the unit web and the transfer sheet, grasp the free edge of the transfer sheet shown in FIG. 2 outwardly with one hand and the line 25 with the other hand and pull in the reaction direction. The transfer sheet and web can be easily separated. As described above, the continuous copying form of the present invention can be separated from the continuous copying form immediately after printing without removing it from the printing machine after being printed by the printing machine.
Even in the case of a one-off occurrence, the copy form can be printed immediately without having to be set in the printing machine each time, and the supply hole in the supply belt is always connected to the supply pin. Because of this, there is no need to send the copy form to the supply device set above the printing section during printing, which is economical since no copy form is produced without printing. In addition, the cutout lines 17 and 18 of the upper web 11
is configured to be easier to cut than the cutout hole lines 17a, 18a of the lower web 12, so that the supply hole does not come off from the supply pin or damage the cutout hole lines 17a, 18a of the lower web 12 due to pulling during cutting. It is extremely easy to cut out.
