Description

Description: TECHNICAL FIELD The present invention relates to a printing method for general documents, technical documents, patent specification documents, and other documents output from a computer. The present invention relates to a text printing method capable of dramatically increasing the amount of paper resources and increasing waste.

<Prior Art> General documents, technical documents, patent specification documents, and the like are intended to be finally deciphered visually by humans and to understand information printed on the documents. Therefore, a document that a human finally sees uses a method of printing or developing characters, figures, and the like on paper or film using ink or photosensitive material while maintaining the two-dimensional image. I have.

On the other hand, a document in which various characters and figures are printed with an image that can be discerned by human eyes requires a large number of documents in order to print a considerable amount of information, and in order to save it, , Space is also needed.

In order to improve the space factor at the time of document storage, it is common practice to convert printed documents into microfilm.

Furthermore, recently, characters and graphics are coded (replaced with numbers, symbols, etc. according to specific rules), and are then recorded on a dedicated recording medium such as a magnetic disk or optical disk in the form of a magnetic pattern or light reflection pattern. So-called filing systems for preservation have also appeared.

<Problems to be Solved by the Invention> The conventional printing method of printing or developing on paper or film using ink or photosensitive material has the convenience that a human can view a document as it is. However, there is an advantage that it can be stored on a recording medium for many years, but there is a problem that the information density is limited by the resolution of the human eye and the information transmission ability cannot be enhanced.

On the other hand, document storage using a microfilm or a filing system can increase the information density, but has a disadvantage that a system for rendering the image visible to humans becomes large-scale.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an information transmission and recording method using paper has been improved, and a transmission and recording method adapted to the importance of information has been adopted. It is an object of the present invention to provide a new document printing method capable of increasing the amount of information that can be printed in (1) and effectively using resources.

<Means for Solving the Problems> A printing method according to the present invention for solving the above-described problems is a method for printing information including characters and figures on paper, and a main part or a part of the information to be printed is directly used. At the same time as printing in a size that can be read in the form of
This is a printing method for printing detailed information of the information or related information with a standardized code signal.

<Operation> The main part or a part of the information printed on the paper can be read by a human as it is.

The portion printed with the standardized code signal is developed in a certain rectangular area and printed as a dot row according to the presence or absence of a dot, so that a large amount of information can be stored in a small area.

The information stored here cannot be read by a human being as it is, but is read out by a readout display as needed, and is displayed on a display unit in a human-readable form (size).

<Example> Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a conceptual diagram for explaining the printing method of the present invention, and FIG. 2 is a diagram showing a conventional printing method, which is compared with the printing contents of FIG.

In the figure, reference numeral 1 denotes paper, which is a thin paper such as ordinary paper or plastic paper. 2 is information printed on a sheet, for example, if it is a paper, its title, 3 is its author, and 4 is an outline of the paper. This information, which is a relatively important part of the dissertation, is printed as it is in a form that can be immediately read by humans, as in a conventional printing method. Further, in the contents of the dissertation, the description portion 5 corresponding to the title of each chapter or each section is printed as it is in a size that can be immediately read by a human.

A blackened portion 6 following the description portion 5 corresponding to the title of each chapter or each section is a coding section in which detailed information related to the title is printed with a standardized code signal.

The coding unit 6 is obtained by developing and printing a standardized code signal in a certain rectangular area, and is capable of storing a large amount of information in a small area.

The information stored here cannot be read by humans as it is, but can be read out using a readout display as needed, and can be displayed on a display unit in a human-readable form (size). It is like that.

According to such a printing method of the present invention, in the case of the conventional printing method shown in FIG.
Printing can be performed so as to be all accommodated in one sheet of paper.

Such a printing method can be performed by using a printer based on information from a computer or information from a word processor.

FIG. 3 is a conceptual diagram showing an example of the configuration of the coding unit 6. As shown in FIG. A code storage area 62 is provided in the rectangular positioning pattern area 61.

The size of the rectangular pattern area 61 is, for example, a rectangle about 8 cm in width and about 1 cm in height here.

FIG. 4 is a diagram showing details of the alignment pattern area 61 and the code storage area 62 provided inside the pattern area 61. In the code storage area 62, for example, one using each dot corresponding to a bit corresponding to the printing resolution of the printer is shown. The pattern area 61 for positioning is also formed of similar dots (three dots in width), and has a checkered pattern here. In this way, the resolution is also expressed, which is convenient for reading.

In the code storage area 62, one byte is represented by 10 dots in the horizontal direction. The breakdown of 10 dots is 8 dots for code, 8 dots for parity, and 1 for each stop bit.
There are as dots.

The vertical direction is also divided every eight characters, and a vertical parity and a stop bit are provided.

Taking the information printed on the code section enclosed by ○ as an example,
By forming a dot array in which b0, b4, and b5 have dot printing (with dots) and b1 to b3, b6, and b7 have no dots, “、 3
1 "=" A ".

The reasons (functions) for providing the alignment pattern, parity bit, stop bit, vertical parity, and vertical block division are as follows.

(Positioning pattern) The display resolution differs depending on the printer that prints the document.
The size of the dot can be determined.

Also, even if the dots are not aligned or distorted during printing in the X and Y directions, the data dots can be read correctly.

(Parity bit) This is for checking reading errors.

(Stop bit) For detecting byte breaks.

(Vertical parity, vertical block division) This is to deal with uneven printing in the vertical direction.

FIG. 5 is a conceptual diagram when the coding unit 6 is read in a document printed by the printing method of the present invention.

Reference numeral 7 denotes a reading display provided for reading the coding unit 6. In this readout display 7, 71
Is a display unit using, for example, a liquid crystal, and 72 is a coding unit 6
For example, a reading unit that optically reads a code is used. Reference numeral 73 denotes a switch provided on the outer frame of the display unit 71.

When the reader wants to know the detailed information printed on the sheet, as shown in the figure, the reading unit 72 approaches the coding unit 6,
The code printed thereon is read, and the code signal is displayed on the display unit 71 as character or graphic information in a human-readable form.

FIG. 6 is a configuration block diagram showing an example of the readout display 7.

The reading section 72 for reading the dot row of the coding section 6 uses a two-dimensional array sensor, and a data signal indicating the dot row is applied to the data processing section 74, where it is converted into a character or a figure corresponding to the dot row. It is configured to be displayed on the display unit 71.

The reading unit 72 has a resolution sufficiently higher than the resolution of print dots of various printers. In addition, an area larger than the maximum area size of the coding unit 6 to be printed can be sensed. In this case, assuming that the area of the coding unit 6 to be printed is 1 cm × 8 cm, the reading unit 72
It is assumed that the size of the sensor reading surface is about 2 cm × 10 cm.

When the printed coding unit 6 completely enters the sensor reading surface of the reading unit 72, even if the relationship between them is slightly inclined, the alignment pattern, the stop bit, the parity bit, the vertical parity, the vertical block division, and the like are determined. By detecting and correcting the read data based on these, accurate information can be extracted.

The display unit 71 converts the read data into characters or figures and displays the read data in a form and size that can be read by human eyes. The existing data processing unit and display unit can also be used by using character codes and graphic codes specified by the standard.

In the readout display having such a configuration, the switch 73 is used.
When is pressed, the information (data) encoded from the dots is read by the reading unit 72, and the information printed on the encoding unit 6 is displayed on the display unit 71 in a form and size that can be read by human eyes. You.

The switch 73 is configured such that when the upper part is pressed, the screen displayed on the display unit 71 is scrolled upward, and when the lower part is pressed, the screen is scrolled downward. It is configured so as to be convenient when it is performed.

According to such a printing method, the paper is printed with a mixture of a character portion and a coded portion using a printer from a computer or a word processor. Therefore, when reading such a printed document, the reader can first read important and important information such as a title and an outline easily and directly in the form of characters and figures. Then, when it is desired to see more detailed information, the reading unit 72 is applied to the document encoding unit 6 using the reading display unit 7, and the contents are displayed on the display unit 71 and read.

In the above embodiment, only the information of the coding unit 6 is displayed on the display unit 7, but the information read from the coding unit 6 may be input to a computer. In this case, the following applications can be expected,
There is an advantage that data and software can be publicized on the same medium at a very low price in a printed document such as a book.

(1) Input of Numeric Data Sequence (2) Input of Program Source List <Effect of the Invention> As described in detail above, according to the present invention, the following various effects can be obtained.

(1) The amount of information of a document using paper such as plain paper can be dramatically increased.

For example, in the area of the coded part of 1 cm x 8 cm, 5 dots / m
Assuming that m is printed and read out, the number of dots that can be printed in this area is 5 (dots) x 10 (mm) x 5 (dots) x 80 (mm) = 20,000.

Assuming that 15% of this number of dots is used for alignment patterns, dots for correction of apologies, etc., and the remaining 85% corresponds to the bit string for information transmission, 20,000 x 0.85 = 17,000 bits = 2.13 bytes .

Since the JIS kanji code is 2 bytes, this is about 1000
Character corresponding. This number of characters is equivalent to the information amount of 0.5 pages of a general technical magazine.

(2) Data other than characters and figures can be transmitted.

For example, it is most suitable for publicizing software such as audio, images, programs, and data strings.

(3) Paper resources can be used effectively.

By converting only necessary information into characters and encoding detailed information and related explanations, the paper can be effectively used.

(4) An existing printer or the like can be used as it is for printing on a document.

This is because by providing a dot group for alignment, it is possible to estimate the print dot density at the time of reading.
