Description

  The present invention relates to valuable printed matter having an asset value such as banknotes, securities, and gift certificates, and in particular, there are a plurality of types of ticket types. A printed matter having an identification element capable of identifying a species.

  Traditionally, various valuable security technologies have been used for valuable printed matter such as banknotes and various securities that have asset value, in order to keep the value of the printed matter beneficial, and there are multiple types of coupons. An identification element for identification is given.

  Most of the identification elements are identified by touching the surface of the printed material with the fingertips (hereinafter referred to as “tactile sensation”) so that visually impaired persons can be identified. It is an identification element (hereinafter referred to as “identification mark”) given to the ticket.

  Currently, the lower right and lower left of the Bank of Japan issued by the Bank of Japan are L-shaped for 10,000 yen, octagon for 5,000 yen, and three round shapes for 2000 yen, In the 1000-yen voucher, a horizontal linear identification mark is formed in a raised shape by intaglio printing.

  Like the identification mark formed on this Bank of Japan note, a general tactile identification mark has a concave-convex shape on the surface of the base material. It becomes possible to identify, and furthermore, by making the shape different for each ticket type, it is possible to identify which ticket type.

  As a technique for improving the identification of the identification mark, the present applicant forms an identification mark on a part of the substrate and attaches an optical change element (specifically, a hologram) in the vicinity of the identification mark. By doing so, the difference in the tactile sensation between the smooth state (smooth feeling) on the surface of the optically variable element and the uneven shape (grainy feeling) of the identification mark, and the shape due to the height difference between the convex portion of the identification mark and the substrate surface Two types of identification methods for confirmation are disclosed (for example, see Patent Document 1).

  Also, as a technique for identifying the ticket type, in addition to the tactile sensation, the sheet itself is folded in half, the upper sheet and the lower sheet are overlapped, and the upper and lower sheets are rubbed against each other in the horizontal direction. A generated sheet, wherein unevenness is arranged in a fixed arrangement on the surface of a part of the upper sheet and the lower sheet of the sheet, and the unevenness is formed by a pair of convex portions and concave portions, and a pair of convex portions And the pitch of the concave portion is divided into the distance of the upper bottom portion of the convex portion and the distance of the lower bottom portion of the concave portion, the length of the lower bottom portion is formed with a length larger than the length of the upper base portion, and the convex portion A sheet that generates special sounds by changing its shape, orientation, and horizontal and vertical dimensions of the convex portion is disclosed (for example, see Patent Document 2).

JP 2004-58605 A JP 2007-268712 A

  However, Patent Document 1 has an identification function that further improves the tactile sensation of the conventional identification mark alone, that is, the tactile sensation due to the difference between the unevenness of the identification mark and the smoothness of the optically variable element. Because it is formed in a convex shape by intaglio printing, the initial convex shape (especially height) cannot be maintained due to various conditions such as friction and pressure in the distribution process of the market. There was a problem that it was difficult to perform the function.

  In addition, since Patent Document 2 performs identification by sound rather than tactile sensation, it is affected by the environment in which identification is performed. If identification is not performed in a relatively quiet environment, the upper side There is a problem that the special sound generated when the sheet and the lower sheet are rubbed together cannot be accurately heard, and furthermore, different special sounds cannot be distinguished for each ticket type.

  Therefore, in the distribution process of the market, such as a printed matter in which a convex shape is formed on the base material with ink, or a printed matter in which a concave shape is formed on the base material with embossing, depending on various situations such as friction and pressure, An identification mark that can be discriminated even if there is some change in the uneven shape (height and depth, etc.) at the initial stage, and that does not affect the external environment such as ambient sounds It was desired.

  Therefore, the present invention makes use of the difference in height between the concave and convex portions of each region when overlapping the identification marks formed in different regions on the substrate, so that the conventional identification marks can be used. An object of the present invention is to provide a precious printed matter that can be distinguished by a sufficient tactile sensation with a height difference of about 2 times.

  In order to solve the above-described problems, the present invention is configured such that two regions composed of concave and / or convex elements are formed on the same surface or different surfaces of a base material, and the two regions are overlapped in a predetermined direction.

  Embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiments described below, and various other embodiments can be implemented within the scope of the technical idea described in the claims.

  FIG. 1 is a diagram showing an example of a true / false discrimination formed body (1) having an identification mark in the present invention. The true / false discrimination formed body (1) of the present invention has different regions on the same surface of the base material (2) as shown in FIG. 1 (a) or different base materials as shown in FIG. 1 (b). The surface has a first identification region (3) and a second identification region (4).

  In the authenticity determination formed body of the present invention, the first identification region (3) and the second identification region (4) are overlapped and shifted in a predetermined direction, whereby low friction resistance and high friction resistance are obtained. Is used for identification.

  As for the base material forming the first identification region (3) and the second identification region (4), paper, plastic, metal, etc., intaglio printing, gravure printing, screen printing, flexographic printing or relief printing can be used. There is no particular limitation as long as it is a material and a base material that can be inserted, laser processed, and embossed. In addition, although the whole base material may be the above-mentioned material, only the area | region which provides a 1st identification area | region (3) and a 2nd identification area | region (4) may be the above-mentioned material.

  In the first identification area (3), as shown in FIG. 2 (a), a plurality of first elements (5) are arranged in a line, and in the second identification area (4), As shown in FIG. 2B, a plurality of second elements (6) are arranged in a line.

Each identification area will be described in detail below. First, as shown in FIG. 3A, the first identification region (3) includes a first element (5) arranged in a line, and a first direction (S ₁ ) and a second direction. Are arranged at different angles in the direction (S ₂ ) and are divided into a low friction region (7) and a high friction region (8). The first element (5) constituting the low friction region (7) is hereinafter referred to as a low friction element (9), and the first element (5) constituting the high friction region (8). ) Is hereinafter referred to as a high friction element (10).

  Note that the definitions of low friction and high friction in the present invention are high friction when the second identification area (4) is overlapped and rubbed to feel a large frictional resistance in the first identification area (3). In addition, the friction resistance is felt to be lower than the high friction, and the base material itself, which is an area other than the first identification area (3), other printed patterns, scratch patterns, holograms, etc. It does not indicate that the frictional resistance is high or low relative to other various components applied on the same substrate.

The first direction (S ₁ ) and the second direction (S ₂ ) may have an angle difference within a range of 30 ° to 90 °, preferably 60 ° to 90 °. is there. When the difference in angle between the first direction (S ₁ ) and the second direction (S ₂ ) is 90 ° or more, one direction, for example, the first direction (S ₁ ) is considered as a reference. When the starting point of the second direction (S ₂ ) is considered on the opposite side, it is also in the range of 30 ° to 90 °, so-called an angle of ± 30 ° to 90 ° with respect to the first direction Become. Therefore, the difference between the first direction (S ₁ ) and the second direction (S ₂ ) in the present invention is generally 30 ° to 90 °. If the difference between both the angles is smaller than 30 °, the low friction area (7) and the high friction area (8), which are the effects of the present invention, cannot be clearly distinguished from each other.

The pitch (P ₁ ) of the low friction elements (9) arranged in a line forming the low friction area (7) is the same as the second element (6) of the second identification area (4) described later. In particular, the arrangement is not limited to regularity, as long as the arrangement has smoothness, and may be in the range of 60 to 200 μm, as shown in FIG. It may be different in the region (7). However, in terms of design, it is preferable to arrange them at a regular pitch.

  Further, as shown in FIG. 3 (a), at least two low friction regions (7) are arranged with the high friction region (8) interposed therebetween. At least two low friction regions (7) are arranged. 3 (b), the pitch of the low friction elements (9) in the two low friction regions (7) may be different, and when three or more are arranged, all the pitches are different. It may be. However, as described above, the same pitch is preferable in terms of design.

  As described above, the fact that the low friction region (7) is arranged with the high friction region (8) interposed therebetween means that the low friction region (7) and the high friction region (8) are alternately arranged. However, since the discriminating effect of the present invention is not necessarily shifted from one direction with respect to the first discriminating region (3), the low friction region (7) is the first discriminating region. It is necessary to arrange on both sides of the region (3), and therefore, the low friction region (7) is arranged one more than the high friction region (8). For example, when two high friction regions (8) are arranged in the first identification region (3), three low friction regions (7) are arranged, and each of them is arranged alternately.

Further, the element width (W ₁ ) (the line width in FIG. 3) of the low friction element (9) is formed in the range of 30 to 1000 μm. This is because if it is formed to be thinner than 30 μm, it will be difficult to form the height of the later-described peak, and if it is thicker than 1000 μm, the design will be uncomfortable.

Further, as shown in FIG. 3 (c), the low friction elements (9) constituting the two low friction regions (7) sandwiching the high friction region (8) are arranged differently in the _first direction (S ₁ ). They may be arranged with angles (θ ₁ ) and (θ ₂ ).

In the present embodiment, the low friction elements (9) constituting the low friction region (7) are arranged at the same pitch, and the arrangement angle (θ) with respect to the first direction (S ₁ ) is the high friction region. The description will be made assuming that the second element (6) constituting (8) is disposed at 90 ° (vertical).

  4A is a cross-sectional view of A1-A2 in the low friction region (7) of FIG. 3A, and FIG. 4B is a first identification region (3) of FIG. 3A. It is sectional drawing of B1-B2. 4 (a) and 4 (b), the low friction element (9) and the high friction element (10), which are the first elements (5), are formed of ink having a predetermined rise (h). The predetermined recess may be formed on the base material by squeezing, laser processing or embossing. Further, the low friction element (9) may be formed by a concave portion, and the high friction element (10) may be formed by a raised ink, and vice versa. ) And the high friction element (10) are preferably formed by the same forming method. In the present embodiment, an example in which each element is formed with ink having a rise will be described.

  In order to form the ink having this swell on the substrate, intaglio printing, gravure printing, screen printing or flexographic printing is used. Also, letterpress printing can be used, but in that case, it is necessary to use foamed ink. As a printing method suitable for forming the bulge, intaglio printing may be used. The raised height (h) depends on the thickness of the base material itself and there is a limit to the ink raised state, so that the raised height (h) is in the range of 20 to 150 μm.

  The foamed ink described above is an ink in which at least a foaming agent is blended in the ink, and when heated, the blended foaming agent foams and the ink layer is raised. Examples of the foamed ink include plastisol ink, water-based ink, organic solvent-type ink, and the like. However, in the present invention, the type of ink used is not particularly limited because the ink may be raised to form a bulge.

  By forming the low friction region (7) so as to have a bulge, it is possible to grasp the location where the identification mark is formed using the height difference with the base material, By eliminating the height difference from the high friction region (8), it is possible to smoothly rub the substrate from the low friction region (7) to the high friction region (8).

  2 to 4, the first element (5) is formed in a line shape by arranging a plurality of lines, but the line of the first element (5) is a straight line. 5 (a) to 5 (c), it may be a dotted line, a wavy line, or a broken line, and a plurality of minute characters to be described later may be arranged in a line shape. However, for the low friction element (9), the first identification area (3) and the second identification area (4) are related to the frictional resistance with the second element (6), which is the effect of the present invention described later. ) Are overlapped and rubbed in a predetermined direction, it is necessary to reduce the frictional resistance as much as possible. The image line in the present invention includes all of the above-described straight lines, dotted lines, wavy lines, broken lines, and those in which minute characters described later are arranged in a plurality of lines, and those in which halftone dots and pixels are arranged in a plurality of lines. .

  When the low friction element (9) is formed by a dotted line or a broken line, it is necessary to shorten the range of the non-image portion (x) shown in FIG. If the non-image portion (x) is lengthened, the frictional resistance increases when the second element (6) is rubbed, and the low friction region (7) and the high friction region (8) The difference in frictional resistance is not clear and proper identification becomes difficult. Therefore, the distance of the non-image portion (x) is formed in the range of 10 to 300 μm.

  Furthermore, when the low friction element (9) is formed by a dotted line and a broken line, as shown in FIG. 6 (b), the position where the non-image portion (x) is arranged is the direction in which the dotted line or the broken line is drawn. If they are arranged on the same line in the vertical direction, a step is produced at that position and the frictional resistance becomes large. Therefore, as shown in FIGS. 6 (c) and 6 (d), each low friction element ( 9) It is preferable not to arrange the position where the non-image portion (x) in 9) is arranged on the same vertical line with respect to the direction in which the dotted line or the broken line is drawn.

Further, the high friction element (10) is not limited to a straight line, but may be a dotted line, a wavy line, or a broken line. Furthermore, as shown in FIG. May be. The high friction region (6) only needs to be arranged in such a manner that the frictional resistance is higher than that of the low friction region (5) described above. Therefore, the high friction region (6) is adjacent to the shape of each high friction element (10) arranged in a line. The pitch (P ₂ ) between the matching high friction elements (10) is important. Therefore, even if the high friction element (10) is formed by a dotted line, a broken line, a halftone dot, or a pixel, the distance of each non-image area (x) is not limited as in the low friction element (9), Further, there is no particular limitation on the preferred arrangement so that the arrangement of the non-image portion (x) between the adjacent high friction elements (10) is not on the same straight line.

  FIG. 8 shows another example of the first element (5). FIG. 8A shows a parallelogram having the same shape, with a plurality of first elements (5) arranged with non-image portions (x) obliquely at regular intervals. The same applies to an image line arranged in a straight line. FIG. 8B shows the first elements (5) arranged in an oblique direction.

  FIG. 8 (c) is a drawing in which minute characters are arranged in a straight line, and FIG. 8 (d) is a drawing in which the first element (5) is formed by a drawing. This is one in which small white characters are formed in the line of the book. 8 (c) and 8 (d) are both formed with a size that is difficult to visually recognize with the naked eye, and therefore, with the naked eye, they are only visually recognized as a line, but when enlarged with a loupe or the like, The characters can be visually recognized, and further anti-counterfeiting effects can be achieved. However, as described above, for any minute character, the pitch between characters and one term (for example, “JAPAN” in FIG. 8C) are used so as not to have a shape and arrangement that impairs the identification function of the present invention. It is necessary to pay attention to the distance between them. Note that in the case of using minute characters as shown in FIG. 8C, it is necessary to arrange minute characters in a line shape so that they are recognized as a single line, so the character height is the line width. The range is 30 to 1000 μm.

  The low-friction element (9), the high-friction element (10), and the second element (6) are not limited to a straight line, and each of the plurality of elements arranged in a dotted line, a broken line, a wavy line, a minute character, or a halftone dot Although it may be arranged in a line, as shown in FIG. 9, in one element, a dotted line, a broken line, a wavy line, a minute character, or a halftone dot may be combined.

  For example, as shown in FIG. 9, in FIG. 9 (a), one low friction element (9) may be formed with a straight line to the middle and formed with minute characters from the middle. ), One low friction element (9) is formed using dotted lines, halftone dots and straight lines.

The pitch (P ₂ ) of the plurality of arranged high friction elements (10) constituting the high friction region (8) needs to be the same as or wider than the element width of the second element (6). If the pitch (P ₂ ) is narrower than the second element (6), the second element (6) will not be fitted between the plurality of arranged high friction elements (10), and the low This is because there is no difference in frictional resistance from the friction region (7). The relationship with the second element (6) will be described in the identification principle of the present invention.

Similarly to the low friction element (9), the high friction element (10) has an element width (W ₂ ) (the line width in FIG. 3) in the range of 30 to 1000 μm. However, since the intended purpose of the high friction element (10) is different from that of the low friction element (9) as described above, the relationship with the element width of the second element (6) is important.

Also, the high friction element (10) is formed by using an ink having a bulge, similar to the low friction element (9). Accordingly, the height (h ₂ ) of the high friction element (10) is formed in the range of 20 to 150 μm, similar to the height (h ₁ ) of the low friction element (9). Note that the heights of the low friction element (9) and the high friction element (10) are not necessarily formed at the same height, and may be different. However, in consideration of design design, it is preferable that the pitch, width and height of the low friction element (9) and the high friction element (10) are the same.

  Next, the second identification area (4) will be described. The second identification area (4) is formed on the same substrate on which the first identification area (3) is formed. However, since it is necessary to overlap and rub the first identification area (3) and the second identification area (4) in order to perform identification, at least when the base material is folded or rolled, It is necessary to form it at a place where it can be overlapped. Therefore, preferably, it forms in the location symmetrical with the location in which the 1st identification area | region (3) was formed with respect to the center of the long side direction of a base material.

  As shown in FIG.1 (b), even when forming the 1st discriminating region (3) and the 2nd discriminating region (4) in the front and back of a base material, it is with respect to the center of the long side direction of a base material. Therefore, it is preferable to form it at a symmetrical place.

In the second identification region (3), as shown in FIG. 10 (a), the second elements (6) are arranged in a plurality of lines in the _third direction (S ₃ ). The third direction (S ₃ ) is identified by the frictional resistance between the second identification region (4) and the high friction region (8) of the first identification region (3). The direction is preferably the same as the _second direction (S ₂ ) in which the high friction elements (10) forming the friction region (8) are arranged. By making the same direction, when the identification is performed, the arrangement direction of the high friction element (10) and the arrangement direction of the second element (6) are changed by bending or rounding the base material at the center line in the long side direction. It becomes the same direction, and proper identification can be performed.

Even if the second direction (S ₂ ) and the third direction (S ₃ ) are not the same direction, the high friction element (10) and the second element (6) are in the same direction when performing identification. It suffices to superimpose so that However, in that case, the high friction element (10) and the second element (6) do not appropriately overlap each other only by bending or rounding the base material at the center line with respect to the long side direction. Needs to be bent or rounded to be slightly twisted. Therefore, since 45 ° is the limit of the angle at which the substrate can be twisted, the relationship between the angles of the second direction (S ₂ ) and the third direction (S ₃ ) is ± 45 °. , Preferably in the same direction.

  Moreover, about the shape of a 2nd element (6), since it is necessary to reduce frictional resistance between low friction elements (9), forming in a straight line is preferable. If the low friction element (9) is formed with a straight line, the second element (6) may be formed with a plurality of characters arranged in a dotted line, a wavy line, a broken line, or an image line. If there is little, there is no problem.

As described above, the relationship between the element width (W ₃ ) and the pitch (P ₃ ) of the second element (6) is important with the high friction element (10). By shifting the base material in a certain direction with the high friction element (10) and the second element (6) overlapped, the uneven shape of the high friction element (10) and the second element (6) is reduced. Since identification is performed by using the fact that the frictional resistance is increased by rubbing, the swelled portion of the high friction element (10) must be fitted between the second elements (6). . Therefore, it is preferable that the second element (6) is also formed of ink having a rise as shown in FIG. 10 (b). The raised height (h ₃ ) of the second element (6) is also formed in the range of 20 to 150 μm, like the low friction element (9) and the high friction element (10). However, it may not be the same as the raised heights of the low friction element (9) and the high friction element (10).

  The low friction element (9), the high friction element (10), and the second element (6), which are the first element (5), have a shape having a rise, but the rise shape is shown in FIG. As shown in (c) to (c), there is no particular limitation as long as it is a polygon or an ellipse such as a rectangle or a triangle and can form a bulge.

  Similarly, the low friction element (9), the high friction element (10), and the second element (6), which are the first elements (5), may be formed by recesses as described above. The shape of the recess is not particularly limited as long as it is a polygon or an ellipse such as a rectangle or a triangle and can form the recess, as shown in FIGS. In addition, about the depth in the case of forming in a recessed part, although depending also on the thickness of a base material, it forms in the range of 20-150 micrometers similarly to the rising height.

In order to have a relationship in which the high friction element (10) and the second element (6) are fitted together, for example, the element width (w ₂ ) of the high friction element (10) is adjacent to each other between the second elements (6). In this case, since the second element (6) needs to fit between the adjacent high friction elements (10), the adjacent high friction elements (10) The distance is equal to or greater than the element width (w ₃ ) of the second element (6), and the distance between the adjacent second elements (6) is equal to or greater than the element width (w ₂ ) of the high friction element (10). It becomes. The so-called pitch (P ₂ ) of the high friction element (10) −the element width (w ₂ ) of the high friction element (10) ≧ the element width (w ₃ ) of the second element (6) and the second element (6) Pitch (P ₃ ) −Element width (w ₃ ) of second element (6) ≧ Element width (w ₂ ) of high friction element (10) Therefore, if both element widths are the same, both pitches have at least twice the element width. The pitch (P ₃ ) of the second element (6) is also formed in the range of 60 to 2000 μm, like the low friction element (9) and the high friction element (10).

Further, the element width (w ₃ ) of the second element (6) is also formed in the range of 30 to 1000 μm, similarly to the low friction element (9) and the high friction element (10).

Next, the principle of overlapping and identifying the first identification area (3) and the second identification area (4) will be described. FIG. 12 is a diagram illustrating a state in which identification is performed using the authenticity determination forming body according to the present invention. In FIG. 12A, first, the base material of the authenticity determination formed body is bent at a predetermined position, and the low friction area (7) and the second identification area (4) of the first identification area (3) are overlapped. It is a figure which shows the state put together. When the low friction region (7) and the second identification region (4) are overlapped, the low friction element (9) forming the low friction region (7) is in the first direction (S ₁ ) ( In the drawing, the second elements (6) arranged in the horizontal direction with respect to the base of the base material and forming the second identification region (4) are in the third direction (S ₃ ) (drawing). In the above, since the elements are arranged in a direction perpendicular to the base of the base material, the respective elements are orthogonal to each other. Therefore, when superimposed, each element is in point contact (M ₁ ) as shown in FIG. Therefore, the friction resistance of the second identification area (4) and the low friction area (7) is low.

From a state where the low friction area (7) and the second identification area (4) of the first identification area (3) are overlapped, the base material is placed in a predetermined direction (direction toward the high friction area (8)). FIG. 13 (a) shows the state shifted. In this state, the second direction (S ₂ ) in which the high friction elements (10) are arranged (in the drawing, the direction perpendicular to the base of the base material) and the second elements (6) are arranged. Since the third direction (S ₃ ) (in the drawing, the direction perpendicular to the base of the substrate) is the same direction, the high friction elements (10) and the second elements (6 ) Is in a line contact (M ₂ ) state at a certain position, and when it is slightly deviated from that position, the second element (6) is fitted between the high friction elements (10). FIG. 13B illustrates this state.

FIG. 13 (c) is a schematic view of the state of FIG. 13 (b) as viewed from above the base material. When both elements overlap each other, it is in a line contact (M ₂ ) state. When the base material is slightly shifted from, the other element is fitted between one element.

By shifting the base material while superposing the high friction region (8) and the second identification region (4), the base material is superimposed while superposing the low friction region (7) and the second identification region (4). The frictional resistance is greater than the frictional resistance when shifting Further, the high-friction element (10) and the second element (6) are in the vertical direction (base material surface) in the line contact (M ₂ ) state and in the state where the other element is fitted between one element. The height difference is generated with respect to the vertical direction, and the substrate (respective areas) is held in a certain direction (here, the second direction (S ₂ ) and the third direction (S ₃ ) while pressing with the finger. ), It becomes possible to feel the difference in elevation continuously.

  In the conventional identification mark, since an identification mark having a concavo-convex shape is only formed in one area, when performing identification, the concavo-convex shape is felt by a finger. The height difference of the present invention was only the height or the depression of the base material, but as described above, by overlapping the two regions, it has a height difference at least twice that of the conventional identification mark, It is possible to feel the touch feeling with a finger quite strongly.

Further, from the state where the high friction area (8) and the second identification area (4) of the first identification area (3) are overlapped, the base material is moved in a predetermined direction (direction toward the low friction area (7)). FIG. 14 shows the state of being shifted. This state is the same as the state where the low friction area (7) and the second identification area (4) of the first identification area (3) are overlapped with each other, and the low friction element (9) and Since the second element (6) is in a point contact (M ₁ ) state, the friction is more than the frictional resistance when the high friction region (8) and the second identification region (4) are shifted while being overlapped. Resistance is reduced. Since the superimposed state is the same as the state of FIG. 12, the details are omitted.

  FIG. 15 shows a series of flows of the identification method in the present invention. The details of each state are the same as described above, and will be omitted. However, by shifting the base material from the state shown in FIG. 15A to the state shown in FIG. From the state where the frictional resistance of a) is low, the state shifts to the state where the frictional resistance is high as shown in FIGS. 15B and 15C, and again to the state where the frictional resistance is low as shown in FIG.

  The above description is the basic principle of the identification method according to the present invention. However, the purpose of the present invention is to provide different types of product values such as banknotes in the same type of printed matter, such as banknotes or gift certificates. Because it is to identify the type of ticket such as 1,000 yen, 5,000 yen and 10,000 yen by tactile sense, it has the original identification function only by recognizing the tactile sensation described above for one type of printed matter. It will not be. An example for identifying different types will be described next.

  In the present invention, the low friction area (7) and the high friction area (8) are arranged adjacent to each other so as to recognize the difference in tactile sensation. The arrangement of the low friction region (7) and the high friction region (8) may be different.

  For example, FIG. 16 shows identification marks formed on different ticket types in the same type of printed matter. FIG. 16 (a) shows a form in which one high friction region (8) is formed between two low friction regions (7), and FIG. 16 (b) shows three low friction regions (7) and two low friction regions (7). Two high friction regions (8) are formed, and the low friction regions (7) and the high friction regions (8) are alternately arranged. FIG. 16C shows a form in which the arrangement direction is 90 ° different from that in FIG. The second identification area (4) has the same form.

  Whether the identification person shown in FIGS. 16 (a) to 16 (c) has one region where the person who performs the identification feels high frictional resistance due to the tactile sensation due to frictional resistance by forming the identification marks in different types of bills. It is possible to identify the type of the ticket depending on which direction is the two or the direction in which the tactile sensation is felt.

  FIG. 16 shows an example in which identification is performed with different numbers depending on the number of the high friction regions (8) arranged and the direction in which the identification is performed. However, the present invention is not limited to this and is shown in FIG. Thus, it is possible to discriminate by the length (z) of the low friction region (7) and the high friction region (8), and it is possible to design appropriately using the basic principle of the present invention. is there.

  In FIG. 17, the example which varied the length of the high friction area | region (8) for every ticket type is shown. In FIG. 17 (a), the length of the high friction region (8) is (Z), whereas in FIG. 17 (b), it has a length (2Z) twice that of FIG. In (c), the length is three times (3Z). Thereby, it becomes possible to identify a ticket type by the difference in length which feels high frictional resistance.

  The identification mark in the present invention can be used for banknotes, gift certificates, etc. having asset values. However, in the passport, the passport for 5 years and 10 years is identified. It may be formed on the page.
