Description

The present invention relates to a print sheet having an information protection function for printing information that requires security protection.
The print paper having the information protection function of the present invention enables information that requires confidentiality protection to be printed directly on the information protection paper that has been bonded to the print paper in advance, thereby facilitating peeling off the information protection paper.

In recent years, services that print various personal information such as gas, water usage, power consumption, etc. on site and distribute them to users as forms have become popular. This service has the advantage of reducing costs in terms of administrative procedures in that it can issue forms to each user, but there is a problem of leakage of personal information such as peeping forms and worries about unauthorized use by workers.
As a method for dealing with such a problem of information leakage, a postcard having an information protection function has been put into practical use.
A postcard with an information protection function is a method in which personal information is concealed by pasting information protection paper covering this area into a postcard area in which personal information has been previously entered.
In this case, in order to peel off the information protection paper, in the vicinity of the corner of the information protection paper, cut out a part to make a step or remove the adhesive paste, and clearly state the caution statement such as "Please open from here" However, a method of reliably peeling the information protection paper from this portion is adopted.
If the paper is thick like a postcard, it is stepped on a part of two overlapping papers, or the paper (sticker label) bonded with an adhesive is raised (one of the paper by cutting) To remove the unnecessary part by winding, etc.), paste removal processing (print on the surface coated with adhesive to eliminate the adhesive force), and implement a method of creating a cut of peeling However, the method of providing information protection function using information protection paper such as postcard on the print paper requires printing work and affixing information protection label, and it takes time to protect information. There is a problem.

In order to save the trouble of pasting information protection paper, there is an attempt to print information that requires confidentiality protection directly from the information protection paper that has been pasted on the print paper. Since it is difficult to process such as postcards, it is difficult to provide a peeling notch, and it is difficult to peel a sheet without any peeling notch.
SUMMARY OF THE INVENTION An object of the present invention is to easily change a thin information protection paper having an information protection function to print information requiring confidentiality protection from information protection paper previously bonded to the print paper as information protection paper. An object of the present invention is to provide a print sheet having an information protection function that can be easily separated from the print sheet so that the user of the print sheet can easily remove the release sheet.

In the present invention, the information protection paper having a concealing property of 20 to 50 μm thick is bonded to the entire upper surface of the printing paper with a bonding strength that does not hinder the running by the printer printing, and in the vicinity of the top of the side surface of the paper, An arc cut that does not reach the tip is provided in the information protection paper that is bonded to the print paper, and it has a configuration that can be peeled between the print paper and the information protection paper laminate layer using the arc cut. The problem is solved by realizing a printing paper having an information protection function.

Since the print paper having the information protection function of the present invention is arranged so that the apex of the cut of the arc line provided on the information protection paper is in contact with the paper edge, by curving the paper, the information protection paper can be removed from the print paper. Since the top of the notch peels off and rises, the information protection paper and the print paper can be easily separated with a weak force by gripping and pulling off the top of the notch that has risen.
In addition, the arc notch provided on the information protection paper has a structure in which the apex is arranged in a direction that does not oppose the printing direction and does not interfere with printing, so the information protection paper and the printing paper are peeled off inside the printer. Designed to be difficult to jam and not jammed.
Information protection paper that has been peeled off by human hands is rolled into a cylindrical shape due to the tension repulsion caused by the adhesive of the information protection paper at the time of peeling, so that it can be discarded into a household trash can. In the case of a roll, it becomes easier to peel off.

FIG. 1 is an explanatory diagram showing an example of the configuration of a print sheet having an information protection function of the present invention. In FIG. 1, (a) is an explanatory view showing an example of the configuration of a print paper having the information protection function of the present invention in a state where the information protection paper is bonded, and (b) has the information protection function of the present invention. It is explanatory drawing which shows the structure of the cross section of the printed paper.
In FIGS. 1A and 1B, reference numeral 10 denotes an information protection paper having a concealing property, and reference numeral 40 denotes a thermal printing paper.

It can be peeled off by force.
The arc line notch 20 has a configuration in which the apex is arranged in a direction that does not oppose the printing direction so as not to interfere with printing running.
The thermal print paper 40 and the information protection paper 10 are bonded together with a bonding layer strength that does not interfere with printing, and after printing, as shown in FIG. The information protection paper 10 is bonded in a configuration that can be peeled between the bonding layers 30.
The information protection paper 10 having a concealing property is limited to a thin one having a thickness of 20 to 50 μm so that sufficient heat transfer to the thermal print paper 40 can be obtained.

Even if the printer head is heated from the top of the information protection paper 10, the thermal print paper 40 can be used for normal visual inspection by using the information protection paper 10 having a thickness of 20 to 50 μm. It has been confirmed that it is possible to print with a print quality that can be read by a character.
In addition, by using information protection paper 10 with a thickness of 20 to 50μ, even if pressure-sensitive printing paper is used for printing paper 10, it is transmitted to printing paper 10 without impairing the printing pressure of the impact printer. Therefore, it is possible to use a pressure-sensitive print paper as the print paper 40.
The information protection paper 10 having a concealing property can be provided with concealing properties by using a paper mixed with a dye such as colored paper or a paper printed with printing ink. The method of mixing the dye and the method of printing the ink are not limited, and any method can be used as long as it can provide concealability. Generally, the hue for hiding is desirably black. A dye or printing ink that can provide a density higher than the color density of thermal paper or pressure sensitive paper is desirable.
