Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Fields] The present invention is directed to the use of optical identification marks such as recorded barcode information, particularly in the above-mentioned applications such as those given to fiber cloth, etc. The present invention relates to an identification mark recording body that allows identification marks to be read accurately and quickly.

In the present invention, the information recorded on an optical identification mark such as a barcode includes, for example, a manufacturer code given by the manufacturer, product item code, processing method, washing method, handling method, size, color, manufacturing date, etc. Various data such as date, store code given by the store, price, etc.
Typical examples include purchasing-related data, and of course, other information useful in various types of business may also be used.

In addition, the mark may be used by the owner of cloth, sewn products, or clothing, bedding, or other items to which the mark-bearing recording material is attached by gluing or sewing.
It may also be information representing information for identifying the owner, depositor, etc.

[Prior Art] In the distribution industry centered on POS (Point of Five Ale) systems, barcode symbols for identifying individual items are widely used.

For example, by reading the barcode at a retail store, the barcode is used for inventory and sales performance management to avoid key personnel at the register or to quickly grasp sales trends.

However, if the identification mark recording body is significantly deformed, there is a problem in that the reading rate by the optical reading device is extremely reduced.

In particular, when the information recording material is fiber cloth, it becomes unreadable due to deformation such as wrinkles and folds, so it has not yet been put into practical use. Currently, it is being used and utilized. Furthermore, even with paper, identification marks such as barcodes are still widely used in items that are easily bent and deformed, and in products and fields that are easily bent and deformed. The current situation is that this has not been done.

[Problems to be Solved by the Invention] In view of the above-mentioned points, the present invention provides a method for recording identification marks even when the recording body is made of flexible paper or fiber cloth.
Solving the problem of deformation of the recording medium during reading,
It is an object of the present invention to provide a new identification mark recording body that makes it possible to significantly improve the reading rate of identification marks.

Note that the identification mark referred to in the present invention refers to barcodes, 0C
R (Optical Character
cognition) etc.,
The standards are not particularly limited as long as they can be optically read and processed by any reading device that conforms to them.

[Means for Solving the Problems] The identification mark recording body of the present invention that achieves the above-mentioned objects has the following features:
An identification mark recording body comprising an information recording material provided with an optical identification mark and a shape memory material.

Further, the identification mark recording body of the present invention is preferably characterized by having a structure in which a shape memory material and an information recording material are laminated, or alternatively,
Preferably, the shape memory material is film-like or plate-like, or preferably, the shape memory material is fibrous or rod-like. Alternatively, preferably, the shape memory material is fixed and present in a structure in which at least a part of the shape memory material is wrapped in the information recording material, or alternatively, preferably, the information recording material is It is characterized in that the material is made of a fiber fabric, and in this case, in particular, the information recording material is made of a fiber fabric mainly composed of ultrafine fibers of 1 to 0.00001 denier. This is a characteristic feature.

[Action Co. The present invention will be explained in detail below.

The term "shape memory material" used in the present invention includes superelastic materials, which means a shape memory material in the narrow sense of the term, meaning that even if the shape memorized at a high temperature is deformed at a low temperature, it returns to its original shape when heated. Alternatively, it may be a superelastic material that deforms very flexibly when external stress is applied, but quickly returns to its original shape when the external stress is removed.

The identification mark recording body of the present invention is composed of an information recording material in which such a shape memory material is used in at least a portion thereof and an optical identification mark is provided.

The identification mark recording body of the present invention has at least a portion of the identification mark recording body made of the shape recording material described above, so that it is not possible to heat the identification mark recording body above the shape recovery temperature or to remove external stress during reading. Accordingly, it is possible to return the recording body to its original shape, that is, the state at the time when the identification mark was recorded, and thereby the optical readability can be greatly improved.

The information recording material used in the present invention may be paper, a translucent film, a transparent film laminated thereon, or a fiber cloth. Alternatively, the identification mark may be directly recorded on the shape memory material.

In particular, when the information recording material is made of so-called fibrous fabrics such as woven or knitted fabrics or non-woven fabrics, these fibrous fabrics are
The present invention produces great effects because it is inherently prone to wrinkles and is difficult to accurately identify.

Furthermore, since the printing quality of barcodes and the like is greatly influenced by the flatness of the surface, when composing the information recording material of the present invention using fiber fabric, the fineness of the constituent fibers should be sufficiently small, and the fibers should be dense and dense. This is an effective method because it can reduce the reading error rate by using a fiber cloth of the same type. According to the findings of the present inventors, in particular, 1 to o, o
oo.

By making the fabric mainly using 1 denier ultrafine fibers, the spacing between the fibers becomes very dense, resulting in a cross-sectional structure with no visible gaps, which is preferable. Furthermore, by applying appropriate external pressure treatment (for example, press treatment) to the surface of the fiber cloth, the arrangement of each ultrafine single fiber becomes even more flat and dense, and the surface structure of the fiber cloth becomes a flat, close-packed structure. , resulting in a surface condition to which the colorant is effectively transferred. That is, it becomes possible to obtain a pattern with a practical density close to that of high-quality paper and clear boundaries. Alternatively, the same effect can be obtained by using a cross-sectional flattened fiber having an oblateness ratio (major axis/minor axis ratio) of 1°5 or more. 1 to 0 above
．． It is more preferable to use ultrafine fibers of 00001 denier and have a cross-sectional aspect ratio of 1.5 or more.

In addition, since fiber fabrics using such ultrafine fibers are extremely flexible, they can easily return their deformed forms to their original forms, and in particular, the effects of using shape memory materials can be improved. , it is also possible to exhibit even greater synergistic effects.

When forming the identification mark recording body of the present invention from a shape memory material and an information recording material, there are no particular limitations, but they may be formed into a structure in which they are layered at least in part, or the recording body may be Preferably, a shape memory material is used for the periphery or other important parts.

The shape memory material can be preferably used in the form of a film or plate, or in the form of fibers or rods.

In particular, according to the findings of the present inventors, the identification mark recording body of the present invention is preferably configured such that the shape memory material exists in a structure in which at least a portion thereof is wrapped in the information recording material, For example, as in one embodiment of the identification mark recording material 1 of the present invention shown in FIG. A structure in which the shape memory material 4 is wrapped around and fixed is preferable.

Alternatively, when the shape memory material 4 is made of a fibrous or rod-like material as in another embodiment shown in FIG. 2, identification can be made by sewing the fibrous or rod-like material The marks can be incorporated into the mark recording body 1. At this time, sewing methods such as rolling stitches and overlocking stitches can be employed.

Of course, it is also possible to use the fibrous shape memory material and make it into a fiber fabric by knitting or non-woven fabric manufacturing technology, or by weaving or knitting it into a part of the fabric, an identification mark can be recorded. It can also be taken into the body.

In addition, in any of the figures, the identification (barcode) mark 2 may have a structure in which it is provided over almost the entirety of the identification mark recording body 1.

When forming a structure in which a shape memory material and an information recording material are laminated, the entire area of both may be mutually laminated, or alternatively, only a part of them may be laminated. It's okay.

Note that the identification mark recording body of the present invention is not limited to a method for recording the identification mark.

In particular, when the identification mark of the present invention is used for distribution of textile products, the information recording body itself may be a part of clothing products, bedding products, or various textile products, or , it may also be used as a textile identification mark tag having the features of the present invention attached to an appropriate item. In other words, small pieces in the form of narrow O-tape that are used by being sewn onto sewn products such as clothing, bedding, or various other products, or attached by appropriate means such as fusing or needle-clamping. For example, it may be a tag on the back of the collar of a shirt or jacket, or a tape indicating the manufacturer's name, material, etc. on the inside of the waist of pants or slacks.
