Abstract

PURPOSE:To improve the reading accuracy of the discrimination code paper of a binary code. CONSTITUTION:Discrimination code paper has an X axis base line 1, a Y axis base line 2, plural small sections 3, a section mark 4 arranged in a grid-shape and an asymmetrical auxiliary display mark 5, and a data display area b is regulated by being surrounded by the X axis base line 1, the Y axis base line 2 and the asymmetrical auxiliary display mark 5. Thus, even if the relative direction and relative reading speed of discrimination code paper and a sensor change and the width and area of a small section change due to a printing error the ruggedness of a stuck surface, etc., the small section can be exactly set, the discrimination code can be always and exactly read and the discrimination accuracy of the discrimination code can be improved.

There is also a method of reading, but you can read multiple codes (example
Area (two-dimensional) sensor of the size of each page
The same purpose can be achieved by using
Line itself, the direction of the Y base line and the position of the auxiliary mark itself
You can read not only the direction of but also the direction of the character string. in this case
Each table is displayed in the direction of X base line 1 and Y base line 2 and the position of auxiliary mark 5.
As described above, the indication area can be determined.
The direction of the character string depending on the position and number of the auxiliary marks 5.
You can also decide. For example, referring to FIG.

It is possible to detect the inside-out pasting and correct it on the memory.
It is possible to cope with a mistake in pasting another code. Change
As shown in FIG. 9, above the subsection 3 in the display area b.
If there is a space between adjacent ones on the bottom left and right
Binary signal marks (black mark) for all subsections 3 in the vertical direction.
(4) Discontinuity between the division mark 4 and the binary signal mark
Is clearly distinguished from the straight X-axis baseline 1 and Y-axis baseline 2.
Since the calculation of the display area b becomes more accurate,
It is convenient. [0016] In addition, the X-axis baseline 1 and the adjacent subsection 3
And between the Y-axis baseline 2 and the adjacent subsection 3
(No signal mark part) is set to connect binary signal marks.
It is possible to separate the straight line from the continuation and both baselines
However, as shown in Fig. 8, the gap (no signal mark part) is intermittently generated.
If present, both baselines can be determined and displayed more accurately and easily.
The rear can be easily determined. FIG. 12A shows both base lines 1 and 2.
The case where the gap g is formed adjacent to
It may be formed in the middle of the small section as shown in b.
By changing the position and number of the
It is used as a command to specify the reading direction of character strings and
Use as instructions for subdivision combinations that make up minutes
You can also Furthermore, as shown in FIG.ⁿSmall wards
By making the interval g exist every minute, one display area is displayed.
Display the binary code corresponding to multiple Kanji characters
I can do it. The flowchart in Fig. 3 shows a single task.
Although it is the first speed processing in the, the memory area of the sensor input
Capture and computation; higher if output can be multitasked
Can speed up. [0017] As described above, the present invention is based on the X-axis baseline.
1, the display area b is determined by the Y-axis base line 2.
2^FourIf you do not divide into the above subsections, for example, horizontal
Even if it is divided into multiple parts only in the vertical direction or in the vertical direction,
The display area can be divided into two horizontal rows.
You may split and display the code in two rows above and below]. Furthermore, the table
Consider the display area as a single subdivision, and
Recorded with other coded marks
The reading area can be read in unlimited directions.
Thus, the object of the first invention can be achieved. Also, the ward
2 by minute processing using the minute mark 4ⁿ[N ≧
4], the line sensor will
Move the sir by hand to move the sensor relative to the identification code paper.
Accurate reading even when the moving speed changes
At the same time, due to the expansion and contraction of the identification code paper and the unevenness of the pasted surface
Precisely even if the effective area for a small section of the sensor changes
It is legible. [0018] In addition, handy computer and other general
You can print the identification code using a simple printer,
You can write the identification code by hand, or use a high-quality barcode.
It is also possible to use plain paper without using paper. SE
Data can be captured if it is within the reading range of the sensor.
Therefore, even if the individual code is large or small or the direction is different, it can be read.
Yes, printout and handwriting by printer
Or a mixture of different types of labels or affixing different labels to the identification code paper
Even when combined, the object of the present invention can be achieved. Transparent magnetic

Become. The remainder of the code, about 57800 (= 65536-7700)
If you register minutes, Thai and Arabic phonetic symbols will also be displayed.
It is possible to read speech synthesis readers for the blind, such as newspapers and magazines.
It can also be used for storage. The X-axis baseline 1 and the Y-axis baseline 2 are
Without making them orthogonal, as shown in FIG.
It is possible to intersect and make subsections of shapes other than square.
It [0019] As described above, according to the present invention, the identification code paper and the security
Always accurate even if the relative direction to the sensor or the relative reading speed changes.
The display area is readable and
It can be read even when mixed with different size and direction)
It Items other than the display area that are not related to the identification code
Even if is recorded, only the display area is determined and predetermined identification is performed.
It is possible to read the code. Furthermore, the identification code
The relative reading speed between the paper and the sensor may change, printing errors,
The width and area of one small section may change due to unevenness on the sticking surface.
Set subdivisions accurately and always read the identification code accurately
Therefore, the identification accuracy of the identification code can be improved.
