[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a one-dimensional code or a two-dimensional code on a cloth or the like by a weaving method.

[0002]

2. Description of the Related Art A one-dimensional code is used by printing it on paper, but a one-dimensional code or a two-dimensional code obtained by weaving it into a cloth or the like through a thread of natural fiber, synthetic fiber or metal fiber is used. Co-
There are no readers yet, and there are no readers to read them.

[0003]

However, if a one-dimensional code can be created on a fabric by using threads of natural fiber, synthetic fiber or metal fiber, it becomes possible to manage the fabric product from the original fabric. A method for creating them is desired. Although the two-dimensional code has not been popularized yet, it has a high information density, and it is useful for further information management by weaving it into a cloth or the like. However, in practice, when weaving a one-dimensional code or a two-dimensional code in a weaving method, the thread for displaying the one-dimensional code or the two-dimensional code is too long, and a part which is loosened from the fabric appears. Therefore, there is a risk that information will be lost due to thread breakage during fabric processing and washing. Therefore, the present invention solves various problems in producing a one-dimensional code or a two-dimensional code and provides a more rational code producing system.

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) FIG. 1 shows a three-dimensional one-dimensional code arranged horizontally, and an example in which the one-dimensional code is created by a loom system through a warp thread 10 and a weft thread 11. The one-dimensional code is ,
"Black thick bar Kb""Black thin bar Ka""White thick bar Sb"
It is composed of "white thin bar Sa". In the loom system, it is not easy to change the thickness and color of the warp yarn 10, but the weft yarn 11 has an advantage that the color and thickness can be easily changed. Therefore, in the present embodiment, a white yarn is used as the warp yarn 10, a weft fixing yarn (white yarn) and a weft information yarn (black yarn) are used as the weft yarn 11, and the warp yarn 10 and the weft fixing yarn 11 are alternately woven to form a cloth (mesh). ) Is created and the one-dimensional code “black thick bar Kb” and “black thin bar Ka” are performed through the lateral information thread (black). The "black thick bar" is three horizontal information threads, the "black thin bar" is one horizontal information thread, and the "white thick bar" and the "white thin bar" are created at similar intervals.

Next, a three-stage type one-dimensional code A1 (black thin bar, white thin bar, black thick bar, white thick bar, shown in FIG.
…), A2 (black thin bar, white thin bar, black thin bar, white thin bar, thick black bar, thick white bar ...), A3 (black thin bar, white thin bar, black thin bar, thin white bar…) A method of forming the warp yarns 10 and the weft yarns 11 will be described. The one-dimensional codes A1, A2, A3 shown in FIG. 1 are woven by different producing methods. First, in the areas other than the one-dimensional code, the horizontal fixing threads, x, y, and z are shifted by 1 pitch from each other,
By alternately weaving with the vertical fixing yarns 10 (abcd ...), this area is displayed in white.

The next weft thread uses the black information thread a to display the code A1 (black thin bar), the code A2 (black thin bar), and the code A3 (black thin bar). And code A1
In contrast to (black thin bar), the horizontal information thread (black thread) a is on the front side (indicated by a solid line in the figure) with respect to the information area of the vertical fixed threads a to g.
One element "black thin bar" is displayed, and both ends are created as fixed points. For the code A2 "black thin bar", one element is created in two split display, and the vertical fixing threads (j to l) and (n to p) are set to the front side.
For, weave on the back side (indicated by the broken line in the figure). as a result,
The code A2 (black thin bar) is divided by the vertical fixing thread m (white), and fixed points are created at both ends and the center. For the code A3 "black thin bar", the transverse information thread (black thread) a is
By weaving with the vertical fixing threads (s to y) alternately,
One element divided into three white vertical fixing threads t, v, and x'is displayed in four divisions, and fixed points are alternately created for the vertical fixing threads 10. Thus, the horizontal information thread (black) can display the one-dimensional code “black thick bar” and “black thin bar” while creating the fixed point. The end of the horizontal information thread a stands by on the back side of the vertical fixed thread and displays the next code.
And continue.

Next, in order to fabricate a cloth (mesh), the horizontal fixing yarn b is offset by 1 pitch from the horizontal fixing yarn z, and is woven alternately with the longitudinal fixing yarn 10. Next, since the cords A1, A2 and A3 are all "white thin bars", the horizontal fixed thread c is the vertical fixed thread 1
Weave alternately with 0 to create a fine white bar. Next, the horizontal fixing yarns d are alternately woven with the warp fixing yarns 10 to make a fabric.

Next, code A1 (black thick bar) and code A2
The display of (black thin bar) and code A3 (black thin bar) will be described. The horizontal information threads e are vertical fixed threads a to g, j to l, and n.
~ P, suwy 'as the front side and the other warp fixing yarn as the back side, the same "black thin bar" as described above can be created and the first code A1 can be created, as well as the code A2 And the creation of code A3 is over. The next horizontal fixing thread f is woven with the vertical fixing thread 10 alternately to form a fabric.
Then, a second "black thick bar" for the cord A1 is created with the following lateral information yarn g, and the cord A2 is made to be the front side for the vertical fixed yarns a to g and the back side for the other vertical fixed yarns.
And the code A3 is displayed as "white thin bar". Horizontal fixed thread h
Creates a cloth, and the next weft information thread i is the third "black thick bar" for code A1, the first "black thick bar" for code A2, and the code A3. "White thin bar"
Is created in the same manner as described above. In the same manner, the fabric (mesh) can be created by weaving the horizontal information yarn and the horizontal fixed yarn with respect to the vertical fixed yarn, and the codes A1, A2 and A3 shown in FIG. 1 can be displayed in different modes.

Considering the creation of the above-mentioned three kinds of one-dimensional codes, the method of creating the one-dimensional code A1 is woven according to the code length (element). There is a concern that a part of the cloth may be released, and the lateral information thread may be cut off when the cloth is processed or washed, and the information may be lost. On the other hand, the weaving method of the cord A3 is woven alternately, so there is no such concern. The weave of the cord A2 is located in the middle. Therefore, when weaving a multi-stage one-dimensional cord, the cord A3 or A2 is preferable.

In the code A2, the horizontal information threads (black) aeg ... Are separated by the vertical fixing threads (white) m, and in the code A3, the horizontal information threads (black) aeg ... are vertical fixing threads (white) tvx '. Is divided into three parts, and in each case, the white part is displayed. Therefore, taking the code A3 as an example, to show the conditions for reading with the CCD sensor, it is necessary to set the thickness of the vertical fixing thread 10 to 1/2 or less of the vertical dimension of the pixel P of the CCD sensor. Specifically, referring to FIG. 2, 1
4 (L1) μ × 200 (L2) μ pixels P are 2000
Assuming that the CCD sensor 43 of the one-dimensional code reader of the array is arranged, the one-dimensional code is imaged through the lens, and if the reduction ratio is 1/2 to 1/3, the allowable length of the one-dimensional code is used. The length is two to three times 200μ (400
˜600 μ). Therefore, if the diameter (L3) of the white vertical fixing thread tvx 'that divides the code A3 is 200 to 300 μ or less, which is half of the above value, the pixel P of the CCD sensor should map only the vertical fixing thread. Instead, it is mapped with a black transverse information thread included. As a result, code A3
Even if there is a vertical fixing thread to be divided as shown in (1), it can be accurately read as information.

As described above, the one-dimensional code displayed in the state in which there is a vertical fixing thread to be divided can prevent the loss of information because there is no place where the information thread is loosened from the cloth, and the information can be easily read through the code reader. It is possible to identify information (black, white). The optical reduction ratio of the one-dimensional code reader is 1/3 ~
If you select 1/4, the thickness of the above-mentioned vertical fixing thread to be divided can be set to 300 to 400μ, and CC
If the vertical dimension L2 of the pixel of the D sensor is 300 μ, a thickness of 300 to 450 μ can be permitted.

Further, it is desirable that the one-dimensional code reader reads in a defocused (blurred) state as shown in FIG. The CCD camera, as shown in FIG.
The object 45 is imaged via the CCD sensor 43 via 2. The distance between the CCD sensor 43 and the lens 42 is L
x, the distance between the lens 42 and the reading port 40a of the main body case is L
Y

In this CCD camera, the normal form is to focus and image a one-dimensional code. In such a state, when the one-dimensional code shown in FIG. Since the (mesh) elephant is mapped, it is desirable to exclude that image, and as a result of various studies, it was found that reading in an out-of-focus (blurred) state is good. It was also found that the same effect can be obtained by further increasing the vertical dimension L2 of the pixel of the CCD sensor 43.

Therefore, as shown in FIG. 3 (B), the distance between the lens 42 and the reading port 40a of the main body 40A can be calculated as shown in FIG. 3 (A).
The method of forming the main body 40B is longer (La> LY) than that of the main body 40, and the method of forming the main body 40B is shorter (Lb <LY) as shown in FIG. 3C. Thus, when the main body 40A, 40B of the conventional reading device is formed and read, the object 45 is imaged in a defocused state,
Reduces the sensitivity of “white” and “black”, making it easier to use “white”,
I was able to identify "black". When reading the one-dimensional code of the present invention, either of the main bodies 40A and 40B may be configured, but the code written on paper or the like is preferably read in a focused state. It is desirable to adopt the main body 40B because it is possible to read the read port 40a of the main body 40B apart from the main body 40B by forming the main body 40B short. The one-dimensional code reader is also effective for a two-dimensional code described later. It should be noted that, in addition to the above-mentioned one-dimensional code reader, a laser type code reader can be used for the same reading. That is, in the laser type code reader, the spot of the laser beam may be controlled to be elliptical, and the major axis of the ellipse may be selected to be at least twice as long as the longitudinal fixed yarn.

Further, when the "black thick bar", "black thin bar", "white thick bar", and "white thin bar" constituting the above-mentioned one-dimensional code are created, the lateral information yarns are fixed yarns (horizontal fixed yarns, longitudinal yarns). Needless to say, the thickness is preferably thicker than the fixed thread, and the thickness and the number of each thread may be selected in consideration of the accuracy of the one-dimensional code code reader and the like. The color of each thread may be selected such that the horizontal information thread can be distinguished from other threads, for example, when the horizontal information thread is white, the horizontal fixed thread and the vertical fixed thread are black. . In addition, the one-dimensional code (FIG. 1) is the horizontal fixed thread zbd before and after the horizontal information thread aegi.
Although it is a method of making it through fg or the like, it is clear that it can be made without using these transverse fixed threads zbdfg. Furthermore, in the one-dimensional code (FIG. 1),
For the “white thin bar” and “white thick bar”, the white fixed yarn is used instead of the fixed horizontal yarn, and the “white thin bar” is used.
The number of lines corresponding to the “white thick bar” can be created (FIG. 1 (C)).

It should be noted that it is desirable to use transparent yarns for the vertical fixed yarns m, t, v, x'for creating the fixed points of the one-dimensional code shown in FIGS. 1B and 1C, and the information yarn a. Is on the back side of the vertical fixing yarns m, t, v, x ', but by using the transparent yarn, the information yarn a can be seen. As a result, the horizontal information threads a, e, ...
Even at a fixed point with x ′, the color of the lateral information thread is displayed, and a continuous one-dimensional code having a fixed length but no break can be created. Further, by using flat yarns or single yarns (non-twisted yarns) for the lateral information yarns a, e, ..., the contour of the one-dimensional code becomes clear and can be easily read by a conventional one-dimensional code reader. it can. In particular, when flat transparent yarns are used for the vertical fixing yarns m, t, v, x ′, the horizontal information yarns a, e, ... While there is a possibility of misreading due to the lens effect of being imaged on the sensor, such a lens effect is eliminated and the possibility of misreading is reduced. Furthermore, the lateral information thread a,
By using a shape memory alloy thread or a shape memory resin thread for e, ..., It becomes possible to prevent the loss of information even after washing or the like.

When the one-dimensional code shown in FIG. 10 (A) is created, for example, as shown in FIG. 10 (B), weft-fixed yarns x, y, z outside the area where the one-dimensional code is displayed. And thermo-bonding fiber yarns are used for the horizontal fixed yarns v and w, and the horizontal fixed yarns x, y, z and the horizontal fixed yarns v, w are set to the vertical fixed yarns x, y,
Alternately woven with respect to z, a ..., The front side and the back side of the thermocompression bonded fiber yarn have the same area. On the other hand, FIG.
In (C), the horizontal fixed yarns w and y and the horizontal fixed yarns u and w ′ of the thermocompression bonding fiber yarn are woven so that they are on the front side with respect to the vertical fixed yarns z, h, q, and z, and the back side. The adhesion area is increased by making the area of the area larger than the area of the front side.
Alternatively, the thermocompression bonding fiber yarn may be thicker than the other yarns so as to increase the bonding area. The one-dimensional code thus created can be easily attached as a code label to other articles by ironing or the like. or,
This one-dimensional label can be easily attached to airbags, clothing, etc. and is useful for management. The thermocompression bonding fiber yarn can be configured to be used as a horizontal fixed yarn (excluding the horizontal information yarn) or a vertical fixed yarn in the area where the one-dimensional code is displayed.

(Second Embodiment) Next, FIG.
This is for the barcode (A3) shown in (A), and a plurality of (one in FIG. 4) "black thin bar" of a one-dimensional code is created. One-dimensional code (A3) is "black thin bar", "white thin bar", "black thin bar", "white thin bar", "black thin bar", "white thin bar", "black thick bar" Configured. Therefore, in the "black thin bar", the lateral information yarn a is alternately woven with respect to the longitudinal fixed yarns a to h, and the next lateral information yarn c is woven with a shift of 1 pitch from the lateral information yarn a. Like this
By weaving the two lateral information threads a and c with a pitch shift, at least one of the lateral information threads is imaged on the CCD sensor, so that accurate information can be displayed and a one-dimensional code can be easily created. , It is possible to prevent information loss due to yarn breakage because it is woven alternately. In the following, the one-dimensional code is created by weaving the lateral information yarn with respect to the longitudinal fixed yarn in the above-mentioned manner. The horizontal fixed threads e and g display a "white thin bar" through the horizontal fixed thread f, and the horizontal information threads y, a ', c', e ',
g'and i'indicate "black thick bar" through the horizontal fixed yarns z, b ', d', f ', and h', and weaving them by adjusting their intervals. In addition, in the creation of the one-dimensional code, it is possible to create without using the horizontal fixed threads b, d, f, ... In the above example, the horizontal information thread is shifted by one pitch. Obviously, the pitch may be shifted by 2 pitches by weaving every two yarns of the warp fixing yarn 10.
Further, in the creation of the one-dimensional code according to this embodiment, various types can be considered in consideration of the thickness of the thread, the accuracy of the reading device, and the like.

(Third Embodiment) In this embodiment, the one-dimensional code (A1, A2, A3) shown in FIG. 1 (A) in the first embodiment is created with the vertical and horizontal directions reversed. To do. That is, the three-stage one-dimensional code (B
1B2, B3), a black horizontal information thread, a white horizontal fixed thread, and a white vertical fixed thread are prepared as shown in FIG. 5 (B). The horizontal fixed yarns xyz are offset from each other by one pitch, and are alternately woven with the vertical fixed yarns 10 to create a white area. For the lateral information thread a, a one-dimensional code of B1 is created for the vertical fixed thread 10 and the black thin bar Ka is provided on the front side of the vertical fixed thread a.
Represents the thin white bar Sa on the back side of the vertical fixed thread b and the thick black bar Kb on the front side of the vertical fixed thread cde, and the same applies to the vertical fixed threads f to m. To Then, the cloth is created by the horizontal fixed thread b, and hereinafter, the horizontal information thread ceg is created in the same manner as the horizontal information thread a to generate the code B1.
Complete. The next horizontal fixed yarn hij indicates a boundary with the cord B2. As described above, a one-dimensional code can be created, and the length between fixed points becomes the longest when the "black thick bar" is displayed for the horizontal information thread. The horizontal fixed thread bdfg provided adjacent to the horizontal information thread aceg is not always necessary and can be read by the reading device shown in FIG.

(Fourth Embodiment) This embodiment is a method of creating a two-dimensional code as shown in FIG. FIG.
(A) shows an example of a two-dimensional code, the information of the cell C11 is "black", C12 is "white", C13 and C14 are "black" .... Next, a method of creating a two-dimensional code will be specifically described with reference to FIG. The display of one cell uses five vertical and horizontal threads, the horizontal information thread is black, and the other threads are white so that they can be identified by the camera. First, the horizontal fixed yarns xyz are shifted by 1 pitch from each other, and the vertical fixed yarns 10
, Which are alternately woven to represent white. Next, cell C1
In order to display 1, C12, C13 ...
"Black" is displayed as the front side for the vertical fixed threads ace, moq .... In this way, the lateral information yarn a is alternately woven with respect to the warp fixed yarn, so that the lateral information yarn is not cut. The next horizontal fixing yarn b is alternately woven with respect to the longitudinal fixing yarn 10. The next lateral information thread c is the same as the lateral information thread a, and the lateral fixed thread d
Creates the lateral information yarn e and the lateral fixed yarn f in the same manner as the fixed yarn b. Hereinafter, a two-dimensional code is created by weaving the lateral information yarns with respect to the longitudinal fixed yarns based on the cell information (black and white) shown in FIG. In the two-dimensional code created in this manner, the horizontal information yarns that display "black" are alternately woven with the longitudinal fixed yarns, so that the fixed points are alternately produced and the yarns can be prevented from being cut.

Further, in the cells C21 and C22, it is necessary to prevent the cell information from continuing to be "white" and "white" and the distance between the fixed points of the horizontal information thread gik from increasing. Therefore, in the lateral information yarn gik, the cell information on the left and right of the boundary yarns (longitudinal control yarns f, l, r) of the cells of the longitudinal fixed yarn 10 is “white”.
When it is "white", it is on the front side with respect to the longitudinal control thread f. Therefore, in the longitudinal control yarn f at the boundary between the cells C21 and C22, the lateral information yarn gik is set to the front side,
The fixed point of the lateral control yarn can be created almost every cell, and a two-dimensional code capable of preventing information loss due to cutting or the like can be created.
In FIG. 6 (B), as described in the first embodiment, the lateral information yarns a, c, e ...
It is preferable to use transparent yarns for the longitudinal fixing yarns b, d, f, h, ... Since they are on the back side because the fixing points are created by d, f, h ,. As a result, the lateral information threads a, c, e ...
While fixed, the vertical fixing yarns b, d, f, h, ... Can be displayed through the watermark, so that continuous information display is possible. or,
It is desirable to use flat yarn, single yarn (non-twisted yarn), shape memory alloy yarn, or shape memory resin yarn as the transverse information yarn. Also, in consideration of using as a label, by using thermocompression bonding fiber yarn for the horizontal fixed yarn (excluding the horizontal information yarn) or the vertical fixed yarn, it can be easily attached to other articles by ironing or the like. You can wear it.

(Fifth Embodiment) Next, FIG. 7 (A)
Is for creating a two-dimensional code by the same creating method as in FIG. 6B, but the color of the longitudinal control thread flr is set to the same "black" as the lateral information thread. As a result, in the created two-dimensional code, the vertical boundaries of cells are displayed in "black". Then, in the two-dimensional code that is premised on the existence of this "black" boundary, each cell information can be confirmed by the existence of such a boundary in the reading device. Figure 7
FIG. 7B employs the lateral control yarn (black) zflr in FIG. 7A to form the lateral boundaries of each cell. This lateral control thread zf
lr is the longitudinal fixed yarns ae, gk, mq ... and the longitudinal control yarn z.
Alternately weave for flr ... to form lateral boundaries of cells. In this two-dimensional code, vertical and horizontal boundaries are created for each cell so that the reading device can distinguish it from other cell information (black, white). As described in the first embodiment, when transparent yarns are used for the vertical fixing yarns b, d, h, j ..., the lateral information yarns a, c, e. d, h,
Although it is on the back side with j ..., it is desirable that it can be displayed transparently and continuous information can be displayed while being fixed. It is desirable to use shape memory alloy thread or shape memory resin thread, and considering that it can be used as a label, use thermocompression bonding fiber thread for horizontal fixed thread (excluding horizontal information thread) or vertical fixed thread. By making it, it can be easily attached to other articles with an iron or the like.

(Sixth Embodiment) In the present embodiment, for each cell information (black) of the two-dimensional code shown in FIG. 6, the horizontal information thread (black) is set to the vertical fixed thread (white) 1. It is created corresponding to a book. Specifically, referring to FIG. 8, since the cell C11 is “black”, the cell C12 is “white”, and the cells C13 and C14 are “black”, the lateral information thread a is the longitudinal fixed threads a, e, g.
The front side and the back side with respect to the vertical fixing yarn c.
Then, in the next horizontal fixation, the fabric is created by weaving the vertical fixation yarns 10 alternately. Next, cells C21 (white), C22
For white (white) and C23 (black), the lateral information thread c is used,
"Black" is displayed on the front side of the vertical fixed thread e. Below, it is created in the same manner based on the information of the two-dimensional code. In this way, for the information (white, black) of the two-dimensional code, the horizontal information thread (black) for the vertical fixed thread (white) is "black".
If it is on the front side and if it is "white" on the back side, the code can be created easily. It is desirable to use a thicker yarn as the lateral information yarn than other fixed yarns.

(Seventh Embodiment) In the present embodiment, the conventional two-dimensional code shown in FIGS. 9A and 9B is created by the method shown in FIG. 8 (FIG. 9A1). ) (A2)
(B1) (B2)). The two-dimensional code shown in FIG. 9 (A) has left edge portions (C (1, 1) to C as positioning information.
(10, 1)) and the lower edge (C (10, 1) to C (10,
10)) is a continuous "black" display. Therefore, FIG.
As shown in (A1), the black lateral information yarn aceg ...
By positioning the white warp fixed yarn a and the black transverse information yarn s on the front side of the white warp fixed yarn aceg ..., a positioning display in which "white" and "black" alternate Become. Further, when the black horizontal information yarns adeg ... Are created on the front side with respect to the white vertical fixed yarns at the location of the information (black) of the two-dimensional code, the code display shown in FIG. 9 (A2) is obtained. Further, FIG. 9B is a positioning type two-dimensional code in which four edges are surrounded by black, and FIG. 9B1 is shown in FIG.
The code shown in FIG. 9B2 is obtained by creating the code information on the cloth or the like by the same method as 1).

However, when the conventional two-dimensional code shown in FIGS. 9A and 9B is changed to the form shown in FIGS. 9A2 and B2, it cannot be read by a commercially available two-dimensional code reader at present. The following methods are available for reading this two-dimensional code. (1) In the conventional two-dimensional code reader, FIG. 9 (A)

(2) In creating the two-dimensional code shown in FIGS. 9A and 9B, the vertical fixed threads zbdfh ... And the horizontal fixed threads zbdfh. Use colored threads. As a result, the information (black, white) of each cell is displayed in a state of being surrounded by a black frame.
The pattern is the same as that illustrated in (B), and reading is possible. (3) When creating the two-dimensional code shown in FIGS. 9A and 9B, the vertical fixed thread zbd that does not display the information of each cell
fh ... and horizontal fixed threads zbdfh ... are used as white ultrafine threads. As a result, the alternating pattern of "black" and "white" in the positioning display is similar to a continuous pattern of black, and can be read by the defocused CCD sensor shown in FIG. 3 or the laser type code reader.

In principle, the one-dimensional or two-dimensional code shown in each of the above figures displays the information while weaving the lateral information yarns alternately with the longitudinal fixed yarns, thereby creating fixed points of the lateral information yarns. However, in consideration of the allowable length between the fixing points of the lateral information thread, the accuracy of the code reader, etc., and in the above-described embodiments, in principle, the lateral information thread and the lateral fixing thread are Although the one-dimensional or two-dimensional code created alternately is illustrated, a combination of a plurality of weft information threads and one (or a plurality of) weft-fixing threads, and further, weft-fixing threads and warp-control threads are eliminated. Needless to say, codes of various formats can be created based on various conditions such as, so that the method of creating the one-dimensional or two-dimensional code created by the present invention is limited to the method described in each of the above embodiments. It is not something that will be done.

Further, in each of the above-mentioned embodiments, the color of the lateral information thread is described as "black", but it is also clear that the color which can distinguish the information display from other fixed threads may be selected. It is also clear that it is preferable for the information display to use a thicker yarn as the lateral information yarn than other fixed yarns.
In addition, by using a transparent thread for the vertical fixed thread, the horizontal information thread creates a fixed point. By using a transparent thread for the vertical fixed thread, the horizontal information thread can be seen through even on the back side. Is desirable because it can display information continuously while being fixed. Furthermore, it is desirable to use a flat yarn, a single yarn (a yarn that is not a twisted yarn), a shape memory alloy yarn, or a shape memory resin yarn as the transverse information yarn, in order to display clear information and prevent information loss. Further, as shown in FIGS. 1B and 1C, when the lateral information yarns a, e, ... Are on the back side to create fixed points for the longitudinal fixed yarns m, t, v, x ′, When flat transparent yarns are used for the vertical fixing yarns m, t, v, x ', the lens effect is eliminated and the possibility of misreading is reduced.

Further, the one-dimensional or two-dimensional code created in each of the above-described embodiments can be easily read by using the CCD sensor in the defocused (blurred) state of the lens shown in FIG. It can be read by a laser type code reader. In addition, the one-dimensional code and the two-dimensional code created in each of the above-mentioned embodiments include a magnetic material such as red iron oxide in the dyeing process, in addition to the use of threads such as natural fiber, chemical fiber, and metal fiber. It is possible to use the transverse information yarn containing the magnetic material. A one-dimensional or two-dimensional code created with such a transverse information thread can be easily read through a magnetic code reader. Furthermore, when the one-dimensional or two-dimensional code created in each of the above-mentioned embodiments is used as a label, a horizontal fixed thread (excluding the horizontal information thread) or a vertical fixed thread used outside or in the area of the code is used. By using thermocompression bonding fiber yarn, you can easily attach it to other articles with an iron, etc.
In order to increase the bonding area of the thermocompression bonding fiber yarn, it is effective to use a thermocompression bonding fiber yarn thicker than other yarns or to make the back side area larger than the front side.
