Description

  The present invention relates to a booklet.

  Terminal devices (hereinafter collectively referred to as ATM) such as an automatic teller machine (ATM) and an automatic passbook carryover machine record deposit / withdrawal information in the user's passbook. ATM stores an unused passbook in a closed state, and issues a new passbook when there is no longer a column for recording deposit / withdrawal information in the passbook inserted by the user. In other words, the ATM turns the cover of the stored unused passbook and prints personal information in return. Then, the ATM records unrecorded deposit / withdrawal information in the newly issued passbook.

  The unused passbook stored in the ATM may be deformed such as warping on its cover due to moisture absorption. When the cover is deformed such as warpage, the suitability of the curling is deteriorated, and a passbook with deformation such as warpage is sometimes clogged in the ATM at the time of issuance.

  Patent Documents 1 and 2 disclose a passbook in which a cover is composed of a cover paper piece and a facing paper piece.

  Specifically, Patent Document 1 is a single-sided water-resistant layer in which each of a cover paper piece and a facing paper piece has a water-resistant layer on one side, and the cover paper piece and the facing paper piece are used as a cover so that their water-resistant layers are both outer surfaces. The passbook is disclosed.

  Patent Document 2 discloses a passbook in which each of the cover paper piece and the facing paper piece is a water-resistant resin-containing water-resistant paper, and a passbook in which each of the cover paper piece and the facing paper piece is a double-sided resin-coated water-resistant paper. Further, Patent Document 2 laminates a cover paper piece that is a resin-impregnated water-resistant paper and a facing paper piece that is a single-sided resin-coated water-resistant paper so that the surface of the facing paper piece on the resin-coated layer side is one main surface of the cover. The bankbook is disclosed.

FIG. 5 is a schematic plan view when the cover of the booklet shown in FIG. 1 is opened and viewed from the cover paper piece side. 6 is a cross-sectional view taken along line VI-VI of the cover body included in the booklet shown in FIG.

  The booklet 1 shown in FIGS. 1, 2, 4 and 5 is a passbook, for example, a deposit passbook or a savings passbook.

  The booklet 1 includes a signature 2 and a cover 3 as shown in FIGS.

First, the signature 2 will be described.
The signature 2 includes one or a plurality of original paper pieces 21.

  The signature 2 is formed by folding a bundle of one or more paper sheets 21 into two. Preferably, the signature 2 is formed by folding a bundle of three to seven main paper pieces 21 into two. The signature 2 is provided with a fold by folding in half.

  The paper piece 21 is a piece of paper on which deposit / withdrawal information, for example, transaction information between a depositor and a financial institution is printed. As the paper sheet piece 21, for example, a paper piece generally used as a paper sheet piece of a passbook can be used.

The signature 2 further includes a first outermost layer 22.
As shown in FIG. 2, the first outermost surface layer 22 covers the surface corresponding to the last page of the paper sheet 21. In FIG. 2, the first outermost surface layer 22 covers the entire surface corresponding to the last page of the signature 2, but it may be partially covered. The size of the area covered by the first outermost surface layer 22 of the last page of the paper piece 21 is not particularly limited as long as the effect of suppressing the occurrence of tampering is obtained. The ratio of the area of the first outermost surface layer 22 to the area of the final page is, for example, 10% or more, and typically 80% or more.

The first outermost surface layer 22 is made of, for example, a mixture containing an inorganic compound as a filler and a resin compound as a binder. The inorganic compound is, for example, at least one selected from the group consisting of barium sulfate, barium carbonate, calcium sulfate, and calcium carbonate. Examples of the resin compound include rosin, silica, and benzophenone.
The first outermost layer 22 may be formed by printing, for example.

Next, the cover 3 will be described.
The cover 3 includes a cover main body 31.

  The cover body 31 is water resistant. Here, water resistance is imparted to the cover body 31 by providing an outer water-resistant layer 52 and an inner water-resistant layer 8 which will be described later.

  The Gurley stiffness of the cover body 31 is typically 8.83 mN to 24.52 mN, preferably 16 mN to 23 mN. The Gurley stiffness is measured according to the JAPAN TAPPI paper pulp test method no. 40: 2000 "paper and paperboard-stiffness test by load bending method-Gurley method".

  The cover body 31 includes a facing paper piece 4 and a cover paper piece 5. The cover body 31 further includes an inner water-resistant layer 8.

  The facing paper piece 4 is a piece of paper, typically non-coated paper, having a Steecht size of 80 seconds or less obtained in accordance with JIS P8122-1976 “Testing Method for the Paper Sickness Size”. Here, the non-coated paper means a piece of paper that does not include a water-resistant layer that covers the entire surface of a paper base layer 41 to be described later.

The basis weight of the facing paper piece 4 is, for example, in the range of 95 g / m ^{2 to} 110 g / m ² . The facing paper piece 4 is typically a paper piece having a Gurley stiffness of 1.0 mN to 5.0 mN. The absolute value of the difference between the underwater elongation of the facing paper piece 4 and the underwater elongation of the cover paper piece 5 described later is 0.12% or less. Here, the elongation in water of a piece of paper refers to the JAPAN TAPPI paper pulp test method no. 27: 2000 "Paper and paperboard-Underwater elongation test method".

  As shown in FIG. 3, the facing paper piece 4 is folded in half so as to sandwich the signature 2, and is bound to the signature 2 by saddle stitching. The saddle stitching herein refers to a binding method in which the facing paper piece 4 and one or a plurality of book paper pieces 21 are stacked to form a bundle, and the bundle is bound on a straight line that becomes a fold of the signature 2. Since the facing paper piece 4 sandwiches the signature 2, a crease is provided at a portion corresponding to the crease of the signature 2. This fold of the facing paper piece 4 corresponds to a portion 6 where the facing paper piece 4 is bound to the signature 2 (hereinafter also referred to as a binding portion 6). For binding, for example, thread binding or sewing binding can be used.

  The inner surface of the folded folded paper piece 4 is a surface facing the signature 2 in a state where the booklet 1 is closed.

The facing paper piece 4 includes a paper base material layer 41.
The paper base material layer 41 typically includes fibers such as cellulose fibers. The paper base layer 41 containing fibers may be impregnated with other components such as wax. Further, the paper base layer 41 may be imparted water resistance to the cover body 3 by impregnating it with other components such as resin.

  The facing paper piece 4 further includes a print area 42 as shown in FIG.

The print area 42 is included, for example, on the surface of the facing paper piece 4 that faces the signature 2. In the print area 42, personal information of a depositor or a savings person is printed by ATM when a passbook is issued. In addition, the print area 42 can be stamped with a seal. When printing or stamping, it is difficult to fix the ink with a piece of paper having too high water resistance, which is particularly problematic when water-based ink is used. As described above, the facing paper piece 4 is a piece of paper having a Steecht size of 80 seconds or less. The surface of the facing paper piece 4 facing the signature 2 is not provided with a water-resistant layer. Therefore, when the printing area 42 of the flip paper piece 4 is printed or stamped with ink such as water-based ink, the ink is quickly absorbed by the flip paper piece 4. In other words, the ink can be fixed immediately after printing or stamping when the booklet 1 is turned over. That is, the booklet 1 is excellent in printability on the side of the cover 3 that is turned over.
The facing paper piece 4 may further include a printing pattern.

  As shown in FIG. 6, the cover paper piece 5 includes a paper base material layer 51 and an outer water-resistant layer 52. As shown in FIGS. 1 and 5, the cover paper piece 5 may include a magnetic recording layer 53 that records personal information and the like as magnetic data on the outer water-resistant layer 52. The cover sheet piece 5 may further include a printing layer.

The cover paper piece 5 is single-sided water-resistant paper, and the basis weight is, for example, in the range of 140 g / m ^{2 to} 150 g / m ² . The cover sheet piece 5 typically has a Gurley stiffness of 5.0 mN to 7.0 mN. Further, as described above, the cover paper piece 5 has an underwater elongation in which the absolute value of the difference from the underwater elongation of the facing paper piece 4 is 0.12% or less.

  The paper base layer 51 is a layer containing, for example, cellulose. The paper base layer 51 typically includes fibers such as cellulose fibers. The paper base layer 51 containing fibers may be impregnated with other components such as wax. Further, the paper base layer 51 may be imparted water resistance to the cover body 3 by impregnating it with other components such as resin.

  The outer water-resistant layer 52 is provided on one main surface of the paper base layer 51 as shown in FIG. As the outer water-resistant layer 52, for example, a layer coated with a water-resistant agent can be used. As the water resistant agent, for example, a resin-based water resistant agent can be used. Examples of the resin water-resistant agent include styrene-butadiene copolymer latex. The outer water-resistant layer 52 is impermeable and suppresses moisture absorption of the paper base material layer 51 via the outer water-resistant layer 52.

  As shown in FIG. 6, the cover paper piece 5 and the facing paper piece 4 are formed between the back surface of the surface of the paper base material layer 51 provided with the outer water-resistant layer 52 and the back surface of the facing surface of the facing paper piece 4 facing the signature 2. Are bonded together through an adhesive layer 7 provided on the substrate. The adhesive layer 7 is made of, for example, an aqueous adhesive. Since the cover paper piece 5 is bonded to the facing paper piece 4, the fold of the cover paper piece 5 is provided at a portion corresponding to the fold of the facing paper piece 4.

  The inner water-resistant layer 8 has a strip shape extending in a direction parallel to the crease of the cover sheet piece 5. As shown in FIG. 6, the inner water-resistant layer 8 covers a portion corresponding to the fold of the cover sheet piece 5 in the back surface of the surface of the paper base material layer 51 on which the outer water-resistant layer 52 is formed.

  The inner water-resistant layer 8 is made of the same material as exemplified for the outer water-resistant layer 52, for example. The inner water-resistant layer 8 is impermeable to water like the outer water-resistant layer 52 and suppresses moisture absorption of the paper base material layer 51 through the inner water-resistant layer 8.

  The width of the inner water-resistant layer 8 in a state where the cover 3 is opened, that is, in a state where the cover 3 is opened so that the cover sheet piece 5 is flat is, for example, equal to or greater than the thickness of the booklet 1 in the state where the cover 3 is closed. is there. Since the thickness of the bankbook is normally about 2 mm, the width of the inner water-resistant layer 8 is typically 2 mm or more with the cover 3 opened. As will be described later, the inner water-resistant layer 8 contributes to the effect of suppressing the opening of the cover 3 due to moisture absorption. If the width of the inner water-resistant layer 8 is narrow, this effect does not appear remarkably.

  Further, the width of the inner water-resistant layer 8 in the state in which the cover 3 is opened is, for example, 8 mm or less, and the facing paper piece 4 and the cover paper piece 5 are bonded with a constant adhesive strength.

  A portion having a multilayer structure composed of the inner water-resistant layer 8 of the cover body 31 and a portion adjacent to the inner water-resistant layer 8 in the thickness direction is referred to as a first portion 9. A portion having a multilayer structure composed of portions adjacent to the first portion 9 in the in-plane direction is referred to as a second portion 10.

  In the first portion 9, the paper base material layer 51 is sandwiched between the inner water-resistant layer 8 and the outer water-resistant layer 52. Accordingly, moisture absorption of the paper base material layer 51 hardly occurs in the first portion 9. Therefore, even if the booklet 1 is left in a high-humidity environment, the cover 3 does not warp and therefore does not open greatly. That is, when this booklet 1 is used as a passbook stored in an ATM, the booklet 1 is excellent in turning ability of the cover 3 and therefore is not easily clogged in the ATM.

  Moreover, the 2nd part 10 contains only the outer side water-resistant layer 52 as a water-resistant layer. Therefore, in the second portion 10, moisture absorption from the outer water-resistant layer 52 side is suppressed, but moisture absorption from the facing paper piece 4 side can occur. If the paper base material layer 51 and the facing paper piece 4 absorb moisture in the second portion 10, the cover 3 may be warped and clogged inside an apparatus such as an ATM. By making the absolute value of the difference from the underwater elongation of the cover sheet piece 5 0.12% or less, warpage of the cover sheet 3 is prevented.

  The cover sheet 3 has an average and maximum value of the warp amount described below with reference to FIG. Normally, in ATM, if the average value of the amount of warpage of the cover is 8 mm or less, the frequency of clogging of the passbook due to the warpage of the cover is sufficiently low, and if the maximum value of the amount of warpage of the cover is 8 mm or less, the warpage of the cover Due to this, the bankbook is rarely clogged. If the absolute value of the difference in elongation in water is large, the amount of warpage of the cover 3 is also large, but the cover 3 of the booklet 1 has an absolute value of difference in elongation in water of the facing paper piece 4 and the cover paper piece 5 as described above. The average value and the maximum value of the warpage amount are 8 mm or less.

FIG. 7 is a diagram for explaining a method for measuring the amount of warpage of the cover.
In this method, first, the front cover 3 is cut to prepare five test pieces 100 having a dimension in the direction 101 of the grain of 80 nm and a dimension in the direction perpendicular to the direction 101 of the grain of 140 nm.

  Next, one of these test pieces 100 is placed on the flat table 102 so that the cover paper piece 5 faces downward, and in the state where the test piece 100 is placed on the flat table 102, an environment having a temperature of 30 ° C. and a humidity of 70%. Leave in for 8 hours. When the cover sheet 3 absorbs moisture, a part of the cover sheet 3 is separated from the plane table 102.

  After the test piece 100 is left in the environment for 8 hours, the maximum distance 103 between the flat table 102 and the test piece 100 is measured. This maximum distance 103 is defined as the amount of warpage of the test piece 100.

  By the above method, the amount of warpage is also measured for other test pieces 100. Then, an average value and a maximum value of these warpage amounts are obtained.

  As described above, when this booklet 1 is used as a passbook stored in an ATM, the passbook in the ATM caused by the clogging of the passbook in the ATM due to the cover being opened widely and the occurrence of warping. Can be prevented.

  Further, as described above, the cover body 31 of the booklet 1 includes the facing paper piece 4 having a steecht size of 80 seconds or less, and the surface of the facing paper piece 4 facing the signature 2 is provided with a water resistant layer. It is not done. For this reason, the booklet 1 is excellent in printability on the facing side of the cover 3.

The cover sheet 3 further includes a second outermost surface layer 32.
As shown in FIGS. 2 and 6, the second outermost surface layer 32 covers the surface corresponding to the reverse side page of the cover body 31. The size of the area covered by the second outermost surface layer 32 in the back-turned page of the cover main body 31 is not particularly limited as long as the effect of suppressing the occurrence of tampering is obtained. The ratio of the area of the second outermost surface layer 32 to the area of the reverse side page of the cover body 31 is, for example, 10% or more, and typically 80% or more.

The second outermost layer 32 is made of the same material as exemplified for the first outermost layer 22, for example.
The second outermost layer 32 may be formed by printing, for example.

  The booklet 1 may include either the first outermost surface layer 22 or the second outermost surface layer 32. Further, both the first outermost surface layer 22 and the second outermost surface layer 32 may be included.

  In the booklet 1, the first outermost surface layer 22 and / or the second outermost surface layer 32 has a friction coefficient between the back-facing page of the cover 3 and the last page of the signature 2, for example, a static friction coefficient and a dynamic friction coefficient, respectively. It is adjusted to be 0.3 or more and less than 0.4 and 0.25 or more and less than 0.35, or the static friction coefficient is 0.4 or more.

  In the booklet 1, when the static friction coefficient and the dynamic friction coefficient between the reverse page of the cover 3 and the final page of the signature 2 are extremely small, the paper piece immediately before the paper piece having the final page of the signature 2 (in FIG. 2, When squeezing (corresponding to C2 ′), tampering occurs. Here, the term “trolling” means that a plurality of paper pieces are rolled at the same time. “Taking” that occurs when hitting C2 ′ means that when hitting C2 ′, the last page (corresponding to C1 ′ in FIG. 2) is also put together.

  In the booklet 1, the surface corresponding to the front facing page of the cover body 31 and the surface corresponding to the first page of the paper sheet 21 are typically not covered by the outermost surface layer. The friction coefficient between the front cover page of the cover body and the first page of the signature is, for example, that the static friction coefficient and the dynamic friction coefficient are less than 0.4 and less than 0.35, respectively, or the static friction coefficient and the dynamic friction coefficient are each 0. .4 or more and less than 0.25.

  When the static friction coefficient and the dynamic friction coefficient between the front cover turning page of the cover and the first page of the signature are extremely large, tampering frequently occurs when the cover of the booklet is turned over by ATM. The tampering that occurs when turning the front cover means that when the cover 3 is turned, the piece of the signature 2 is rolled simultaneously with the cover 3.

  It is preferable that the static friction coefficient and the dynamic friction coefficient between the reverse page of the cover 3 and the final page of the signature 2 are 0.4 or more and 0.35 or more, respectively. It is preferable that the static friction coefficient and the dynamic friction coefficient between the front facing page of the cover 3 and the first page of the signature 2 are less than 0.4 and less than 0.25, respectively.

The booklet 1 shown in FIGS. 1 to 6 can be variously modified and improved.
For example, the position where the inner water-resistant layer 8 is formed may not be the back surface of the surface of the paper base material layer 51 where the outer water-resistant layer 52 is provided. The inner water-resistant layer 8 may cover, for example, a portion 6 of one main surface of the facing paper piece 4 where the facing paper piece 4 is bound to the signature 2. If the inner water-resistant layer 8 is provided so as to face the outer water-resistant layer 52 with the paper base material layer 51 interposed therebetween, the inner water-resistant layer 8 works in cooperation with the outer water-resistant layer 52 so that the paper base material layer from both the front and back sides of the front cover The moisture absorption to 51 can be suppressed, and as a result, the cover 3 can be prevented from opening greatly.

  In the case where the inner water-resistant layer 8 is provided on a portion 6 of one main surface of the facing paper piece 4 where the facing paper piece 4 is bound to the signature 2, the inner water-resistant layer 8 is the main water-proof layer 8 on the cover paper piece 5 side of the facing paper piece 4. The surface may be covered, and the main surface of the facing paper piece 4 on the signature 2 side may be covered.

  Further, the booklet 1 may not include the inner water-resistant layer 8. FIG. 8 is a cross-sectional view of the cover of a booklet that does not include the inner water-resistant layer 8. The cover 3 shown in FIG. 8 is the same as the cover 3 included in the booklet 1 described with reference to FIGS. 1 to 6 except that the inner waterproof layer 8 is not included.

  According to another modification, the absolute value of the difference between the underwater elongation of the facing paper piece 4 and the underwater elongation of the cover paper piece 5 may be out of the above-described range.

  Further, the Gurley stiffness and basis weight of the paper piece used in the booklet may be out of the above-described range.

  Furthermore, the booklet 1 may further include components other than those described in the drawings. For example, a slip varnish layer may be formed in a portion other than the print area 42.

  Other structures may be adopted for the cover body 31. For example, the inner water resistant layer 8 may be omitted.

  Alternatively, the cover main body 31 may further include a water-resistant layer that covers a surface located inside when the booklet 1 is closed in the paper base material layer 41. In this case, one or both of the water resistant layers 8 and 52 may be omitted.

  At least one of the paper base layers 41 and 51 may be impregnated with resin, thereby imparting water resistance to the cover body 31. In this case, one or both of the water resistant layers 8 and 52 may be omitted.

  Note that, as an aspect of the present invention, a bankbook has been described as an example, but the present invention can also be applied to a booklet other than a bankbook. That is, the booklet 1 may be, for example, a passport, a brochure, a book, or the like.

Examples Hereinafter, examples of the present invention will be described.

(Example 1)
In this example, a booklet similar to that described with reference to FIGS. 1 to 6 except that the inner water-resistant layer 8 is omitted, that is, FIGS. 1 to 6 except that the structure shown in FIG. 8 is adopted. A booklet similar to that described with reference was prepared. The booklet was produced according to the following method.

  First, a predetermined printing pattern was formed on the facing paper piece 4 and the main paper piece 21.

The dial paper 4, using a non-coated paper was internally added Gurley stiffness 1.0mN to 5.0 mN, a basis weight of 95 g / ^{m 2} to 110g / ^{m 2} wax. In addition, as the paper sheet piece 21, a paper piece generally used as a paper sheet piece of a passbook was used.

Next, the second outermost surface layer 32 and the first outermost surface layer 22 were formed on the facing paper piece 4 and the main paper piece 21, respectively, by printing.
The second outermost layer 32 was formed so as to cover 90% of the surface corresponding to the reverse side page of the facing paper piece 4. Further, the paper sheet piece 21 was formed so that the first outermost layer 22 covers 90% of the surface corresponding to the last page of the paper sheet piece 21.

  As the material of the first outermost layer 22 and the second outermost layer 32, a mixture containing a filler made of barium sulfate, barium carbonate, calcium sulfate or calcium carbonate and a binder made of rosin, silica and benzophenone was used.

  The facing paper piece 4 and a bundle including the seven pieces of the paper sheet 21 were superposed, and the obtained bundle was bound by sewing as shown in FIG.

Next, four-color printing was performed on the cover paper piece 5 to form a predetermined printing pattern. As the cover paper piece 5, a paper piece having a Gurley stiffness of 5.0 mN to 7.0 mN and a basis weight of 140 g / m ^{2 to} 150 g / m ² was used.
Furthermore, a latex water-resistant layer was printed on one side of the paper piece.

  Thereafter, the cover paper piece 5 was bonded to the back surface of the facing paper piece 21 of the bundle of facing paper pieces 4 obtained by the above-described sewing binding using an aqueous emulsion adhesive. When the Gurley stiffness of the cover body 31 produced by bonding the facing paper piece 4 and the cover paper piece 5 was determined according to the method described above, it was 16 mN to 23 mN.

  Subsequently, the bundle including the paper sheet piece 21 and the cover body 31 obtained by bonding with the adhesive was folded in two along the portion where the paper sheet piece 21 and the facing paper piece 4 were bound together. Further, drying and aging were performed to obtain a booklet.

  20 booklets were prepared as described above. Hereinafter, these booklets are referred to as “booklet A”.

  Further, 20 booklets were prepared in the same manner as described for the booklet A except that a slip varnish layer was formed instead of the first outermost layer 22 and the second outermost layer 32. Hereinafter, these booklets are referred to as “booklet B”.

  Further, 20 booklets were prepared by the same method as described for the booklet A except that the second outermost surface layer 32 was not formed. Hereinafter, these booklets are referred to as “booklet F”.

  Further, the first and second outermost surface layers 22 and 32 are not formed, but the outermost surface layer is formed so as to cover 90% of the surface corresponding to the front facing page of the paper piece 4, and the outermost surface layer is formed as a paper sheet piece. Twenty booklets were prepared in the same manner as described for booklet A, except that 90% of the surface corresponding to the first page of 21 was formed. As the material of the outermost layer, a mixture containing a filler made of barium sulfate, barium carbonate, calcium sulfate or calcium carbonate and a binder made of rosin, silica and benzophenone was used. Hereinafter, these booklets are referred to as “booklet G”.

  Further, the booklet is obtained by the same method as described for the booklet G except that the slip varnish layer is formed on the surface corresponding to the front facing page of the facing paper piece 4 and the surface corresponding to the first page of the paper sheet 21. 20 books were created.

  Further, a booklet is produced in the same manner as described for the booklet G except that the outermost surface layer is not formed on the surface corresponding to the front facing page of the facing paper piece 4 and the surface corresponding to the first page of the paper sheet 21. 20 bodies were made. Hereinafter, these booklets are referred to as “booklet K”.

  Further, 20 booklets were prepared in the same manner as described for the booklet G except that the outermost surface layer was formed only on the surface corresponding to the front facing page of the facing paper piece 4. Hereinafter, these booklets are referred to as “booklet L”.

(Example 2)
In this example, the suitability of the booklet created in Example 1 was tested using ATM.

  First, the produced booklets A to L were stored in a commonly used ATM, the ATM was operated, and the occurrence of tampering was examined. Specifically, the occurrence of tampering when the front cover was turned and the paper piece immediately preceding the paper piece having the last page of the signature 2 (corresponding to C2 'in FIG. 2) was examined.

  Tables 1 and 2 below show the results obtained for the static and dynamic friction coefficients, and the occurrence of tampering.

  In the table, “◯” indicates that no tampering occurred in all 20 books. “Δ” indicates that tampering occurred in one or two of the 20 books. “X” indicates that tampering occurred in 3 or more of 20 books.

  In addition, since it cannot be assumed that the dynamic friction coefficient becomes larger than the static friction coefficient, such cases are indicated by hatching in the table.

Table 1 shows the static friction coefficient and the dynamic friction coefficient between the reverse side page of the cover 3 and the last page of the signature 2, and the occurrence of tampering when the paper piece preceding the paper piece having the final page of the signature 2 is rolled. It is a thing.

Table 2 shows the static friction coefficient and the dynamic friction coefficient between the front facing page of the cover 3 and the first page of the signature 2, and the occurrence of tampering when the cover is turned.

  From Table 1, the static friction coefficient and the dynamic friction coefficient of the reverse page of the cover 3 and the final page of the signature 2 are 0.3 or more and less than 0.4 and 0.25 or more and less than 0.35, respectively, or the static friction coefficient As for the booklets having a size of 0.4 or more, that is, booklets A, D, E, and F, no tampering occurred in all 20 booklets, or 1 to 2 of 20 books even if they occurred. The book and the frequency of occurrence were shown to be relatively low.

  On the other hand, for the booklets in which the static friction coefficient and the dynamic friction coefficient of the back cover page of the cover 3 and the final page of the signature 2 are less than 0.4 and less than 0.25, respectively, that is, the booklets B and C are 3 It was shown that frequent occurrence occurred in books and more, and the frequency of occurrence was high.

  Also, from Table 2, the static friction coefficient and the dynamic friction coefficient of the cover page of the cover 3 and the first page of the signature 2 are less than 0.4 and less than 0.35, respectively, or the static friction coefficient and the dynamic friction coefficient are respectively For booklets of 0.4 or more and less than 0.25, ie, booklets H, I, J, and K, no tampering occurred in all 20 booklets or even 20 One or two books, showing that the frequency of occurrence is relatively low.

  On the other hand, for the booklets having the static friction coefficient and the dynamic friction coefficient of 0.4 or more and 0.25 or more on the first page of the cover 3 and the first page of the signature 2, respectively, the booklets L and G are 3 out of 20. It was shown that frequent occurrence occurred in books and more, and the frequency of occurrence was high.

  According to these embodiments, when the friction coefficient and the dynamic friction coefficient of the back page of the cover 3 and the last page of the signature 2 are increased, the occurrence frequency of the tampering is low, whereas the front page of the cover 3 is reversed. When the static friction coefficient and the dynamic friction coefficient on the first page of the signature 2 are increased, the occurrence frequency of tampering is high.

  Therefore, when a booklet having a water-resistant cover is stored and used in an ATM, the friction coefficient and the dynamic friction coefficient of the back cover page of the cover 3 and the last page of the signature 2 are increased, By reducing the static friction coefficient and the dynamic friction coefficient on the first page of the signature 2, the occurrence of tampering can be prevented.
