With recent advances in information processing technology, recorded documents, report documents, and the like are mainly generated as a collection of text data by keyboard input. Text data can be easily added, changed and deleted without a trace. In other words, information that is not true may exist and circulate as true information. It is important to generate and distribute trustworthy and true information in an information society that is becoming more and more advanced.

There is no appropriate means to deal with text data as a base. Therefore, an old method is adopted in which a recording original is obtained by recording on a paper medium with a writing instrument. However, this record original alone has the risk of being rewritten or lost, leading to the present invention.

The present invention includes the same contents as physical paper medium recording by placing a paper medium for recording on a placement part on a pressure sensor and recording with a writing instrument (ball pen, mechanical pencil, etc.). A digital record based on a time cycle can be obtained.

Digital recording becomes handwriting information by taking handwritten points (including coordinate values and writing pressure values) for each stroke from the pressure sensor in time series.

The time information and position information received from GPS in the synchronization cycle are attached to the handwriting information as GPS information.

Handwriting information and GPS information are integrated into a database as handwriting record information, and when, where, and who created this recorded document by searching using time information, position information, and handwriting image as key Can be accurately reproduced.

In a society full of a lot of information, it helps to purify information by distributing as much true and reliable information as possible with confidence.

Components of the processing apparatus 100 are a CPU, a ROM, a RAM, an I / O port, and the like.

The paper medium placement sensor 6, the power switch 7, the output transmission button 8, and the mode switching button 20 are devices for instructing the start of the main body, the output of acquired information, and the end of operation via the I / O port of the control circuit 101. is there.

A display 30, a display display item selection button 31, a selection decision button 32, and a display display scroll knob (rotary type) 33 are devices for confirming the operating status of the main body and instructing the next action.

The wireless transceiver 300 and the USB port 400 are devices used for exchanging information with external devices. In particular, the wireless transceiver can receive and display messages from other external devices on the display 30 in a text format by setting its own mail address.

Details of the handwriting information will be described with reference to FIGS.

A case where the paper medium 50 is placed on the placement unit 4 of the information recording apparatus 1 and the katakana “a” is handwritten using the writing instrument 2 will be taken as an example.

The pressure-sensitive sensor board 3 is installed in substantially the same range as the placement unit 4 of the information recording apparatus 1. The upper left corner is the origin of the XY coordinate value 0.0.

Acquisition of handwriting point information of the first stroke starts when the tip of the writing instrument 2 comes into contact with the paper medium 50 on the pressure-sensitive sensor board 3 and the pressure-sensitive sensor board 3 senses the writing pressure. As an example, it is P ₁ (P is an abbreviation for point), and when the handwriting continues, the movement position of the handwriting is continuously acquired as the XY coordinate value for each time cycle transmitted from the control circuit. When the pen pressure is detected, the first stroke ends. If Shimese example a _P 1 to P _7. (Fig. 4)

Followed by a second Brushes eyes handwriting point _is a _P 8 _{~P 11.} The letter “a” is completed with two strokes.

In addition to the XY coordinate values, the handwriting points are displayed in three stages of S = start, C = continuous, and E = end. In addition, the writing pressure level is given in numerical form.

From the pressure-sensitive sensor board 3, three types of pressure-sensitive sensor information, that is, an XY coordinate value, a handwriting state, and a writing pressure level can be acquired for each handwriting point based on a time cycle.

On the other hand, time information and position information are acquired from the GPS receiver 200. Although the time information is very accurate but in units of seconds, the processing apparatus 100 changes the time information to units of 1/100 second to make a time cycle in the information recording apparatus 1. The location information is used as acquired.

The XY coordinate value, the handwriting state, and the writing pressure level for each handwriting point acquired from the pressure-sensitive sensor board 3 are collectively pressure-sensitive sensor information, and the time information and position information are generally GPS information.

Information obtained by synchronizing pressure-sensitive sensor information and GPS information on the basis of a time cycle and integrating and generating them in units of handwriting points is a table shown in FIG. 5, and information of this content is handwriting recording information.

The handwritten record information is compressed by omitting the unchanged part because the amount of information becomes enormous.

FIG. 6 is a flowchart showing a process in which handwriting record information is generated from the stage where the recorder starts recording.

Next, another embodiment relating to handwriting information processing will be described with reference to FIG.

If the recorder has created a recorded document using the information recording device 1 in the past, but the document is not found, if the part of the recorded content is known, find the target document with the text or figure as a clue It is an attempt to put out.
