In addition, on the information description surface of the electronic pen form, the form name, for example, “application form”, caution text, item name in the information entry column, background pattern, and other designs are printed.

  The light source used for the electronic pen 1 is often a light source in the infrared region, and the dot pattern exclusively for reading the electronic pen is printed with ink having a low reflectance in the infrared region, and the surface on which the dot pattern is printed, Caution wordings, item names in the information entry field, background patterns, and other designs are printed with ink having high reflectivity in the infrared region.

Here, an input system using the electronic pen and the electronic pen dedicated paper will be described with reference to FIG.
The electronic pen 1 includes a normal writing unit, an imaging unit (not shown) for reading the dot pattern 2100 printed on the information description surface of the electronic pen form 2, a communication unit (not shown), and the like. is doing.
In the electronic pen 1, when the writer describes characters or the like on the electronic pen form with the electronic pen, the image pickup unit incorporated in the electronic pen is moved by the pen and stroke coordinate information displayed by the dot pattern 2100 ( Hereinafter, the coordinate data is simply read, and the communication unit transmits the read coordinate information to a connected communication terminal (not shown).
The coordinate information received by the communication terminal is transmitted to an electronic pen system management server (not shown) connected on the network. The coordinate data converted into text data by the electronic pen system management server is returned to the server on the user side or the communication terminal.
When the electronic pen system management server function is built in the communication terminal, it is converted into text data by the electronic pen system management server function.

First, the electronic pen 1 will be described with reference to FIG.
The electronic pen 1 includes a writing unit 106 with an ink cartridge 108, an imaging unit 105 using a digital camera that reads a dot pattern, a storage unit 103 that stores writing information (dot pattern coordinate information) read by the digital camera, and mobile communication. A communication unit 102 that transmits coordinate information to a terminal, a control unit 104 that controls these functions, a pressure sensor 107 for an electronic pen, and a power supply unit (not shown), which are arranged inside the casing 101 of the electronic pen 1 It is mounted on.
The electronic pen 1 reads the dot pattern information printed on the paper dedicated to the electronic pen by the imaging unit 105 and stores it in the storage unit 103. Although not shown, the electronic pen 1 and the unique identification information of the electronic pen are connected from the communication unit 102 to the portable communication terminal. 2 to send.
The communication unit 102 is compatible with USB (Universal Serial Bus) or Bluetooth.
The writing unit 106 incorporated in the housing 101 of the electronic pen 1 can also be used as a simple writing instrument.

The writing unit 106 plays a role of making the distance between the imaging unit 105 by the digital camera and the dot pattern printing surface constant, in addition to the role of leaving the writing information in the description unit in a visible state.
When the writing unit 106 is attached to the electronic pen housing 101, the tip on the ink cartridge 108 side comes into contact with the pressure sensor 107 for the electronic pen attached to the electronic pen housing 101.
The pressure sensor 107 has a function of notifying the control unit 104 that information description is started and a function of recognizing the strength of writing pressure.
In addition, when checking the remaining amount of the ink cartridge 108 or filling ink, for example, the writing unit 106 is pulled out from the tip of the electronic pen housing 101 to check the remaining amount of ink or fill the ink. Do.

With reference to FIG. 5, the dot pattern for electronic pens printed on the electronic pen form will be described.
The vertical and horizontal virtual lines shown in the figure are shown for ease of explanation, and are not actually printed.
Each dot of the dot pattern dedicated to the electronic pen is arranged and formed in one of four different directions near the intersection of vertical and horizontal imaginary lines that intersect at right angles formed at intervals of 0.3 mm.
In the above-mentioned “Anoto” system, 36 dots (a group of dots printed on the inner side of about 4 mm ² ) are handled as one unit information.

When characters etc. are written on the electronic pen form with the electronic pen, the position of the pen tip is traced, the coordinate information of the dot pattern printed in the vicinity is read, and the locus of unit information that the pen tip has moved is read. This is stored in the storage unit of the electronic pen.
When a predetermined part of the electronic pen form is marked with the electronic pen, the coordinate information described in the electronic pen form is transmitted from the electronic pen to the communication terminal.
In the “Anoto” system, one application is managed so that the same dot pattern is not used.

The electronic pen system management server will be described.
In many cases, the electronic pen system management server is divided into a PLS server and an ASH server.
The coordinate information transmitted from the communication terminal is first transmitted to an electronic pen system management server called PLS (Paper Look-up Service).
The PLS server determines the application being used from the received coordinate information of the dot pattern, and sends the URL (Uniform Resource Locator) and coordinate information of the ASH (Application Service Handler) server that supports the application to the communication terminal. .

The above communication terminal will be described.
The communication terminal is, for example, a mobile phone, PDA (PDA) having input means such as a keyboard, transmission / reception means connected to the Internet for transmitting / receiving input information, display means such as a display, and storage means for storing input information and read information. (Personal Digital Assistance), a personal computer.
As described above, the communication terminal transmits the information transmitted from the electronic pen 1 to the electronic pen system management server, and receives and uses it as information converted into text data or the like.

An example of the electronic pen form according to the present invention will be described with reference to FIG.
In FIG. 2, a is the information writing surface (dot pattern printing surface) of the electronic pen form 2 (“application form”), b is the back of FIG. A printed on the entire surface with colored ink, c The figure shows the back side of FIG. A printed in a solid shape with colored ink only on the back side area of the information description surface.
In FIG. 2, in the example of FIG. 2A, five information description columns 211 are provided on the information description surface 21 and a dot pattern is printed on the entire surface, but a dot pattern is printed only on the five information description columns 211. May be.

As described above, a dot pattern is printed on the entire surface of the information description surface 21 of FIG. A with infrared absorbing ink, and the inside of the frame of the five information description fields 211 is printed with other inks. There is no section.
Moreover, the back surface 22 of a figure shown to b figure is printed with the colored ink containing white and silver.
When light in the infrared region is irradiated from the information description surface 21, the back pattern read through the base material of the electronic pen form (in many cases, paper) must not adversely affect the reading of the dot pattern. It ’s good.
As for the area 221 printed in a solid shape in FIG. c, the back pattern read through the base material of the electronic pen form (in many cases, paper) is the dot pattern as described in FIG. The reading should not be adversely affected.

With reference to FIG. 3, an example of the effect of the solid pattern printed on the back surface of the electronic pen form of the present invention will be described.
The electronic pen form 2 shown in FIG. 3 is a modified example of FIG. 2a in which a dot pattern is printed only in the five information description fields 211 on the information description surface.
It is assumed that when information is written on the electronic pen form 2, the information is written with an underlay 3.
In that case, as can be seen from the portion other than the information description column 211, the diagonal line pattern formed on the underlay passes through the base material of the electronic pen form 2 and is photographed by the imaging unit of the electronic pen.
However, if the back surface of the information description column 211 is printed as a solid pattern on the entire surface and reflects light in the infrared wavelength region, it is not affected by the diagonal pattern formed on the underlay.
Even when the solid pattern shown in FIG. 2b extends over the entire surface, the effect can be easily estimated as in the case of the partial formation described above.

(Example)
A high-quality paper of 64 gm ² was used as the base material for the electronic pen form.
For the dot pattern on the information description surface, a commercial ink (gray) having an absorption region in the infrared region (wavelength 900 nm) was used.
Create a gray color with a commercially available UV curable process ink, create a solid pattern on the back side of the information writing surface of the electronic pen form, and the thickness of the printing ink to be 2 μm in a dry state. Printed on.
Newspaper was laid on the back side of the electronic pen form created as described above, and characters were written with the electronic pen on the dot pattern printing surface, but the solid pattern printed on part of the back side of the information writing surface It was literally converted to text data written on the pen.
On the other hand, some characters written with an electronic pen in a portion where no solid pattern was printed were not correctly converted into text data.

  Both sides of paper cannot be used as an information description medium, and it can be used for electronic pen-dedicated papers that are limited in cost.

It is a figure for demonstrating an example of the electronic pen and the form for electronic pens of this invention. It is a figure for demonstrating an example of the electronic pen form of this invention. It is a figure for demonstrating an example of the effect of the solid pattern printed on the back surface of the electronic pen form of this invention.
