Description

[Detailed description of the invention]

[0001]

INVENTION The present invention relates to a relates to a sheet for duplex printing, in particular, double-sided printer printable paper size is specified, it relates to printable duplex printing sheet even more defined size.

[0002]

2. Description of the Related Art In a conventional printer having a double-sided printing function, for example, in a single-piece non-impact printer, a printable paper size is specified, and two-sided printing can be performed on a sheet of a predetermined size or more. could not.

[0003]

For this reason, conventionally, the above-mentioned printer is extremely inconvenient because the use of the printer is limited due to the limitation of the paper size. An object of the present invention is to provide a double-sided printing sheet which can solve the above-mentioned inconvenience and can print even a specified size or more.

[0004]

SUMMARY OF THE INVENTION The double-sided printing sheet of the present invention to achieve this object, the sheet is two-folded, while bonding the mating surfaces together releasably, against
Each of the exposed surfaces in the wearing state is a printed surface.

[0005]

[Action] After printing on the front and back print surfaces that are exposed in the state of overlapping and bonding , peeling off the superposed surface,
The folded sheet is twice as large,
A4 size printer that can print A4 size
Printed on three size sheets.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Here, FIG. 1 is a schematic plan view showing a printed sheet, FIG. 2 is a sectional view taken along line AA, FIG. 3 is a plan view showing the sheet opened, and FIG. FIG. 5 and FIG. 5 are schematic cross-sectional views showing an embodiment applied to an adhesive sheet, and FIG. 6 is a cross-sectional view in a state where the sheet is opened.

First, a first embodiment will be described with reference to FIGS. As shown in FIGS. 1 and 2, the sheet 1 is folded in two, and the size in the folded state is the maximum printable size of a target duplex printer (not shown), for example, A4 size. . Then, the superposed surface of the sheet 1 is pre-applied, usually does not adhere, but can be adhered by applying a predetermined pressure, and is releasably adhered by the pressure-sensitive adhesive 2 which can be peeled off after the adhesion. I have. This pressure-sensitive adhesive 2 is made of, for example, natural rubber 10
0 parts by weight, 2 parts by weight of styrene and 10 parts of methacrylic acid
Parts by weight of a natural rubber latex obtained by graft copolymerization with 5 parts by weight of a terpene resin-based tackifier.
It is preferable to add a mixture obtained by adding 20 parts by weight of silica gel having an average particle size of 5 μm.

On the other hand, the exposed surface of the sheet 1 is the printed surface 3
a, 3b, and appropriate information 4, 5 is printed on these print surfaces 3a, 3b by the above-described double-sided printer. A notch 6 is provided at one corner of the printed surface 3a of the sheet 1 so that a finger can be put on the sheet 1 to easily perform a peeling operation when the overlapping surface of the sheet 1 is peeled.

Since the present embodiment is constructed as described above, when a finger is put on the notch 6 of the printed sheet 1 and the releasable superposed surface is peeled off, the sheet shown in FIG.
And as shown in FIG. 4, twice the size of the folded state,
In other words, if the sheet is folded in two and the size is A4, the size becomes A3 and the print surface 3 located on the same side
Sheet 1 on which appropriate information 4 and 5 are printed on a and 3b
Becomes

Next, an example in which the present invention is applied to an adhesive sheet according to a second embodiment will be described with reference to FIGS. The adhesive sheet 11 is folded in two, and the size in the folded state is the maximum printable size of a target double-sided printer (not shown), for example, A4 size, as in the first embodiment. Then, the sheet 11
The superposed surface has a pressure-sensitive adhesive 12 and a release agent 13 which have high adhesive strength and cannot be peeled off after bonding, are applied in advance so as to face each other, and are thereby bonded in a peelable manner.

On the other hand, the exposed surfaces of the adhesive sheet 11 are printed surfaces 14a and 14b.
4b, the appropriate information 15, 16 is printed by the double-sided printer described above.

Since the present embodiment is constructed as described above, when the releasable superposed surface of the printed adhesive sheet 11 is peeled off, as shown in FIG. Size, that is, A in folded state
If the size is 4, the size is A3, and the appropriate information 1 is printed on the print surfaces 14a and 14b located on the same surface side.
5 and 16 become the printed adhesive sheet 11 and can be adhered to a desired position with the exposed adhesive 12. Thus, the adhesive sheet 11 has an advantage that a protective sheet such as a release paper provided for covering and protecting the adhesive surface is not required.

The present invention is not limited to the above-described embodiment. For example, in addition to the above-described structure, the overlapping surface may be quasi-bonded by close-pressing or the like. It is possible to employ a configuration in which two resin films adhered to the substrate are interposed, or a peelable adhesive is applied only to one side of the superposed surface.

[0014]

[Effect of the invention] As is clear from the above explanation,
According to the present invention, the sheet is folded in two, and the overlapping surfaces are releasably bonded to each other, while the exposed surface is a printed surface.
This produces an effect that a printed sheet having a size twice as large as the maximum printable size of the printer can be obtained.
