Description

  The present invention relates to an electronic pen dedicated sheet, and more particularly to an electronic pen dedicated sheet in which a phosphor is mixed in printing ink printed on an electronic pen dedicated sheet so that the electronic pen dedicated sheet is not used illegally.

Conventionally, when submitting various documents such as application forms and application forms, the applicant has filled out the necessary information on the application form on which the prescribed printing has been performed and submitted it.
In recent years, there have been many ways to submit documents, such as printing the above-mentioned forms acquired on the Internet, filling out the necessary items and submitting them by mail, or entering and sending data directly into the displayed forms. Options are expanding.

However, not all those who wish to apply can print out and use forms retrieved via the Internet as described above, or input and send data directly on the screen to the retrieved forms for submission. In particular, an elderly person or a person unfamiliar with a personal computer first shows a refusal reaction to an input with a keyboard.
As a result, government offices and financial institutions have to leave a method of submitting them on paper forms that have been used in the past. However, in recent years, convenient input systems have been provided for such subjects. This is a system developed by “Anoto” in Sweden, which uses an electronic pen called anotopen (hereinafter simply referred to as an electronic pen) and an electronic pen dedicated paper on which a predetermined dot pattern is printed.
The electronic pen includes a normal writing unit, an imaging unit for reading a dot pattern printed on the writing surface of the electronic pen dedicated paper, a communication unit compatible with Bluetooth or USB, and the like.
In the electronic pen, when a writer writes characters on the electronic pen dedicated paper, the electronic pen's imaging unit reads the dot pattern on the electronic pen dedicated paper as the pen moves, and the user writes it. The input data such as the selected character is stored as electronic data.
This input data is transmitted from the electronic pen to a nearby communication terminal such as a personal computer or a mobile phone by, for example, a Bluetooth compatible communication unit.
Even the subject who feels resistance to the keyboard can use the above-described system using the electronic pen without any resistance because the electronic pen functions as a keyboard.
On the other hand, in government offices and financial institutions that provide systems, input data transmitted by a system using an electronic pen can be handled in the same way as data transmitted from a personal computer. There is no need to do it.

  In such a system using an electronic pen, an “electronic pen dedicated paper” is provided in which a protective layer is formed of a transparent material on a portion to be described multiple times on the electronic pen dedicated paper (see, for example, Patent Document 1). ).

In the example shown in FIG. 2, ruled lines, check boxes, “USB” characters, etc. printed together do not emit light. That is, in the case of the electronic pen dedicated paper shown in the figure, the phosphor is mixed only in the ink used for printing the dot pattern of the ink marked on the electronic pen dedicated paper.

With reference to FIG. 3, another example of the electronic pen dedicated paper of the present invention will be described.
The example of the electronic pen dedicated paper shown in the figure shows a visible pattern when a part of the electronic pen dedicated paper 100 in the lower right of FIG. 1 is cut out and irradiated with ultraviolet rays or infrared rays.
The visible pattern indicates a state where the phosphor mixed in the printing ink of the ruled line 12 and the check box 13 (including the characters “USB”) emits light.
In the example shown in FIG. 3, the dot pattern printed together does not emit light. That is, in the case of the electronic pen dedicated paper shown in the figure, the phosphor is mixed in the ink used for printing the ruled lines 12 and the check boxes 13 (including the characters “USB”) marked on the electronic pen dedicated paper. This is an example.

Here, the phosphor (ultraviolet light emitting fluorescent agent and infrared light emitting fluorescent agent) mixed in the printing ink will be described.
As the printing ink used as a base, for example, an ultraviolet drying type process ink or an ink color-matched with these inks is used.
In addition, as the printing ink serving as the base of the dot pattern printing ink, a commercially available ultraviolet drying type ink that is absorbed in the light source wavelength region of the imaging unit of the electronic pen is used.

The ultraviolet light emitting fluorescent agent is excited by ultraviolet light and has a peak of emission spectrum in the wavelength range of blue, green, red, etc., and emits light to high purity phosphors of zinc sulfide or alkaline earth metal sulfide. In order to make it stronger, an activator is added and obtained by high-temperature baking.
A small amount of metal such as copper, silver, manganese, or bismuth is used as an activator.

As an infrared light emitting fluorescent agent, there is an infrared visible conversion fluorescent agent that is excited by infrared light and emits visible light. In order to cause the infrared-visible conversion fluorescent agent to emit light, visible light emission is excited by using a plurality of low-energy infrared photons.
As the type of excitation, there are a type performed by multistage excitation in the activator ion and a type performed by multiple times of resonance energy transfer from the sensitizer.
Commercially available phosphors are used for both the ultraviolet light-emitting fluorescent agent and the infrared light-emitting fluorescent agent, and are mixed in the process ink in the range of 0.05 to 1% by mass as described above.

(Example)
UV-free fluorescent offset ink UV / BF / SG (manufactured by The Inktec) UV-colored fluorescent medium ink (manufactured by The Inktech) 1% was added (the content of the phosphor with respect to the dot pattern printing ink was 0.1% by mass).
UV / BF / SG UV-drying offset ink UV / BF / SG (manufactured by The Inktec) as an ink for dot pattern printing with an infrared-emitting fluorescent agent UVM SDP 10 medium ink (The Inktech) 1% was added (the phosphor content was 0.1% by mass with respect to the dot pattern printing ink).
Further, as a determination tool, a commercially available ultraviolet irradiation lamp with a wavelength of 360 nm (manufactured by Toshiba) and a commercially available infrared irradiation lamp with a wavelength of 980 nm (manufactured by Japan System) were used.
Those mixed with the ultraviolet light-emitting fluorescent agent emitted purple light when irradiated with ultraviolet rays, and those mixed with the infrared-visible conversion fluorescent agent emitted green light when irradiated with infrared light.
