Description

  The present invention relates to a booklet in a form in which a plurality of sheets such as a book, a notebook, a note, a memo pad, a slip, and a book are stacked, and a copy book which is an embodiment of such a booklet.

  General booklets formed by stacking multiple sheets of paper, such as books, notebooks, notes, notepads, slips, books, etc., are manufactured through the process of cutting the required number of stacked sheets, usually on the spelling side The three cut surfaces except for are exposed. Here, “paper” refers to the paper that has been cut to a predetermined size from the base paper, and “cutting surface” refers to the edge of the paper that is the cross-section of the base paper that is expressed as a result of the cutting described above. This means the surface formed by the process. The three cut surfaces exposed in this way are in a state in which the ground color of the paper appears, but the books, notebooks, notebooks, books, etc., where the cut surface is coated with paint or gold foil to increase the product value. Etc. also exist (for example, refer nonpatent literature 1). Thus, the color applied to the cut surface is usually one color. In addition, by providing a colored region (a plurality of colors may be used) different from the paper color in the vicinity of the edge on the front surface (or back surface) of the paper, the color of the colored region can be seen from the cutting surface side. There is also a booklet. In such a booklet, as a result of a small part of the colored area being exposed to the cut surface side due to slight misalignment in the cutting process or bookbinding process of a multi-layered sheet, it looks as if the cut surface is colored. Although this color is used for a headline mark or the like, the cut surface itself represents the background color of the paper.

In addition to these, there is a so-called carbonless copy book that does not use carbon paper, in which the cut surface is colored blue or black. This phenomenon is due to the following structural factors of the copy book itself. That is, in general, a carbonless copy book has an upper sheet coated with a color-encapsulating microcapsule on the back surface, a colorant that flows out of the microcapsule destroyed by pressure, and a color developer that exhibits a color reaction on the surface. A copy form with multiple layers of coated lower paper, or one or more sheets coated with a developer and a microcapsule with built-in color developer between the upper paper and lower paper as described above. The bookbinding is performed by binding one end of the copy form group in which a plurality of medium sheets are stacked as a set. When the upper paper is written with a pen or the like, the microcapsule coated on the back surface of the upper paper or the middle paper is destroyed by the writing pressure, and the internal colorant flows out, and the surface of the middle paper or the lower paper By reacting with the developer applied on the surface and coloring, the same characters as those written on the upper sheet are copied on the surface of the middle sheet or the lower sheet. The copy book having such a configuration is such that the upper paper and the lower paper, or the upper paper, the middle paper, and the lower paper are stacked in the order of the copy form group and a plurality of the paper sets are stacked, or In addition to this, a front cover base paper is provided on the upper base paper, and a back cover base paper is provided in advance under the lower base paper before cutting, and a required portion is cut in a direction perpendicular to the paper surface. By doing so, a plurality of sets of a plurality of stacked copy form groups are obtained, and the state before bookbinding is finished. Here, when the blade is inserted into the base paper by the cutting machine, the microcapsules at the cutting position are destroyed by the pressure received from the cutting edge, and as a result, the reaction between the color developer and the developer on the cut surface in a set of multiple copy forms Color development occurs. Therefore, a color based on the reaction between the color former and the developer is colored on the cut surface of the copy book as a product. In the past, the book was printed and sold as a copy book with the color of the cut surface remaining, but when the copy book in that state was displayed at a store, it was displayed side by side with notebooks with a particularly white cut surface. In some cases, the cut surface of the copy book will be noticeably raised due to coloration, which may damage the scenery in the store, and the color of the cut surface may change to a spotted pattern over time due to sunlight, etc. If there is a chip in the blade, rain patterns may appear on the cut surface, which may impair the appearance of the copy book itself and reduce the product value. Various methods for making colors appear have been considered. As such a method, for example, a color developer is partially applied only to an area necessary for copying excluding a portion to be cut, not the entire surface of the middle sheet or the lower sheet, and color is not generated on the cut surface. And a method in which desensitizing ink that suppresses the reaction between the color former and the developer is printed in advance on each base paper portion corresponding to the edge of the surface of the middle sheet or lower sheet (for example, And Patent Document 1), and a method of applying a decoloring agent to the cut surface that has developed color after cutting (Japanese Patent Application No. 2004-072937).

  By the way, in various booklets, the product name, model number, manufacturer, logo, and other characters, symbols, patterns, etc. are displayed on the cover (one of front cover, back cover, back cover). In general, no indication is usually made on the cut surface composed of a set of edges of the paper constituting the booklet. In other words, as described above, the cut surface of various booklets is colored due to structural factors such as whether the background color of the paper appears or is colored to increase the commercial value, or a carbonless copy book. It is basically a single color that falls under any of the above, etc., but it is currently not actively used to display the cut surface as described above is there. When such a booklet is arranged on a bookshelf or desk drawer with the above-mentioned various notations invisible or difficult to see from the user, that is, when the booklet is arranged with the back cover facing backward, If the back cover is arranged in a state where it faces another booklet, it is difficult to determine which booklet is what, and it may be difficult to take out the target booklet immediately. For example, in the case of a book such as a dictionary, headings are indicated on the cut surface (in Japanese language dictionary, Japanese-English dictionary, etc., Japanese syllabary such as “A”, “I”, “U”, etc .; Etc.), but when such printing is applied to the cut surface, which is a bundle of paper edges, the closely stacked papers are bonded together due to the viscosity of the ink. There is a problem that it will be in a state and hinder page turning.

  On the other hand, especially for carbonless copy books, various techniques for eliminating the color appearing on the cut surface as described above have been considered, but it is troublesome to apply the developer only to the required location. The problem that the desensitizing agent and decoloring agent are relatively expensive and the manufacturing cost is high, and if the desensitizing agent or decoloring agent accidentally adheres to the surface of the paper, it should be copied in the original place. There are various problems, such as the problem that color development may be hindered and the product may become a fatal defective product. Therefore, there is a need for a cheaper, reliable and simple technique for leaving no color on the cut surface.

  Accordingly, in view of the above problems, the present invention has a first object of providing a new booklet that can utilize the cut surface as a new display area that has not been used so far, and a technique similar to this. The second object is to provide a carbonless copy book with a beautiful finish by removing the color of the cut surface using the.

  That is, the booklet of the present invention is bound in a state in which a plurality of sheets are stacked, and the cut surface is partially removed without contact with the cut surface formed by a set of edges of each sheet. A notation made up of characters, symbols, figures, patterns, etc. is formed by the non-contact removing means, and the cut surface is a display area having the notation.

  Note that the “booklet” in this specification refers to all books, notebooks, notes, notepads, slips, books (books, magazines), etc. that are provided in a state in which a plurality of sheets are superimposed. Including. The “cutting surface” refers to a portion of the booklet where the edges of the stacked sheets continuously form a “surface”. Furthermore, “notation” is composed of letters, symbols, patterns, etc. Specifically, the product name, product number, model number, sales code, manufacturing or sales company name of the booklet, the company logo, and falsification prevention The figure, pattern, name of the user by the name putting service, and other appropriate characters, figures, patterns, etc. are applicable. The non-contact removing means literally removes the cut surface without physically contacting the cut surface. Specifically, the non-contact removing means is a powerful light (visible light, invisible (ultraviolet, infrared, laser). (Including light), heat, etc.

  In the case of such a booklet of the present invention, the front cover, back cover, and back cover are not limited to the display area of the product name, model number, logo, etc. as in the conventional booklet, but also have a cut surface. A new display area can be used. In addition, some of the conventional booklets display the heading notation on the cut surface by printing. However, if the notation is formed in a non-contact manner as in the present invention, the papers are bonded to each other by ink to turn the page. Problems such as troubles or bleeding due to ink cannot occur. A laser beam can be mentioned as a particularly effective non-contact removal means. In this way, if a notation is formed by partially and instantaneously sublimating or evaporating and removing the cut surface by irradiation with laser light or the like, characters, figures, patterns, etc. can be drawn freely, small or large. The present invention can be applied to booklets of all aspects. In addition, unlike the case where the notation is engraved on the cut surface with a blade, no shavings, notation errors or misalignment occur. Furthermore, in order to irradiate the cut surface of the booklet with laser light or the like, for example, if laser light irradiation is performed in a state where a plurality of booklets are stacked, irradiation of the cut surface of the plurality of booklets is performed. The notation can be formed all at once, and the space, time, and cost for such processing can also be reduced.

  When binding a booklet on one end side, practically, the cutting surface that forms the display area by a non-contact removing means such as irradiating a laser beam or the like, the binding side on which a plurality of sheets are bound by bookbinding What is necessary is just to set it as the cutting surface which consists of a collection of edge edges other than an edge.

  As a preferable embodiment of the notation on the cut surface, the portion removed by the non-contact removing means such as the laser beam irradiated on the cut surface is described above, or the laser beam irradiated on the cut surface, etc. The remaining portion that has not been removed by the non-contact removing means is the above-described notation.

  When the cutting surface is coated with a paint or foil of a color different from the background color of the paper, the above notation is partially applied to the paint or foil together with the cutting surface by non-contact removing means such as laser light irradiation. By removing them, the contrast between the portion irradiated with laser light and the portion not irradiated with light can be clarified and a clear notation can be formed.

  A suitable booklet to which the present invention can be applied is a carbonless copy book. In such a copy book, the upper paper coated with the color former-containing microcapsules on the back surface, and the color developer that flows out of the microcapsules broken by the pressure and the color developer exhibiting the color reaction are coated on the surface. A carbonless type of paper that has been layered with the lower paper that has been processed, or one or more medium papers that have been coated with a developer-coated microcapsule on the back surface between the upper paper and the lower paper. It has one or more copies of a set of copy forms, and one or more sets of base paper sets in which the upper paper, lower paper, or upper paper, middle paper, and lower paper are stacked in the order of the copy form set are stacked. In this state, one or more sets of copy form sets are obtained by cutting a required portion in a direction perpendicular to the paper surface. If this is the case, it will be indicated by non-contact removal means such as laser light irradiation on the cut surface that has developed color by the reaction between the color former and the developer due to the cutting pressure in one or more sets of cut copy forms. By forming the cut surface, it is possible to actively and effectively utilize the cut surface as a new display area by using the color on the cut surface of the copy book that has been made unnecessary so far. In addition, since there is no need to use desensitizers and decolorizers, the cost of using them can be greatly reduced, and desensitizers adhere to the surface of paper that requires color development, resulting in defective products. There is no risk of occurrence.

  In addition to the above, as a booklet to which the present invention can be suitably applied, for example, a dictionary, a catalog, etc., a plurality of sheets are said to be at the edge part contacting at least one of the front and back surfaces. Examples include those having colored portions of different colors, and those colored portions that are visible from the side of the cut surface as a color different from the cut surface. In this case, the colored portion of the cut surface is visually recognized. It is desirable to form it at a site. By doing so, even if the portion removed by the non-contact removing means such as laser irradiation and the portion that has not been removed are the same color, the cut surface is caused by slight misalignment or sheerness of the stacked sheets Since the colored portion is visible, the above notation can be clearly displayed.

  In addition, in a booklet in which the paper is separable leaving the binding source end including the binding source side edge after bookbinding, the above-mentioned notation is left after the partial separation of the paper. By forming it on the cutting surface other than the edge on the binding origin side at the edge, it is possible to display the notation on the remaining portion at the binding edge even after the paper is cut off, until all the paper is used up It is possible to make the notation on the cut surface work.

  Note that the above notation is not separated from the paper as long as the paper is a booklet that can be separated by leaving a part, even if the paper is not separated from the paper by leaving the original end side. If it is formed on the cut surface of the remaining portion, the notation on the cut surface can be made to function until all the sheets have been used in the same manner as described above.

  In addition, among the booklets according to the present invention, in particular, the copy book includes an upper sheet coated with a color-encapsulating microcapsule on the back surface, and a color developing agent that exhibits a color-developing reaction with the color-developing agent that flows out of the microcapsule that has been destroyed by pressure. Overlay the lower paper with the colorant coated on the surface, or one or more medium papers with the developer on the surface and the microcapsules with color developer on the back surface between the upper paper and the lower paper. It has one or more sets of multi-layered carbonless copy forms, and one base sheet set in which upper paper and lower paper, or upper paper, middle paper, and lower paper are stacked in the order of the above-mentioned copy forms. A set of one or more copies of a cut form that is obtained by cutting a required portion in a direction perpendicular to the paper surface in a state where the set or a plurality of sets are stacked. Refusal By removing the cut surface by a non-contact removing means such as irradiating a laser beam to the cut surface by generating a color due to the reaction between the color former and the developer by pressure, the color development is erased and the cut surface is moved to the cut surface. It is characterized by exposing the background color of the paper.

  In this way, even in the case of a carbonless copy book, even if inevitable coloring occurs on the cut surface due to the cutting pressure, the cut surface is sublimated by performing processing by means of non-contact removing means such as laser irradiation. Or, by evaporating it, the color can be erased, eliminating the need to apply desensitizers and decolorizers as before, and reducing the cost. A copy book with a surface can be obtained. In particular, when laser light is applied as a non-contact removal means, microcapsules containing a color developer impregnated in paper and developer are also lost by sublimation or evaporation along with the cut surface at the part irradiated with laser light. To do. Therefore, if the cut surface that is colored by bringing the blade into physical contact with the surface is scraped off, a new color is generated due to the contact pressure of the blade, but in the present invention, laser light without physical contact is generated. Since the cut surface is superficially removed by non-contact removing means such as irradiation, the ground color of the paper can be exposed on the cut surface without generating a new color.

  In such a copy book, since a back cover may be formed by sticking a tape or the like on the binding side, non-contact removing means such as laser light irradiation on the cutting side of the binding side By performing processing by non-contact removal means such as laser light irradiation over almost the entire cut surface other than the cut surface that becomes the binding side when one or more sets of copy forms are bound. It is sufficient to expose the background color of the paper to the cut surface subjected to the removal process.

  In particular, in this type of copy book, at least one of the upper sheet, the lower sheet, and the middle sheet may be separable leaving the binding source end including the binding source side edge after bookbinding. In many cases, in order for the notation to remain on the cut surface of the copy book even after the used paper is cut off, such a notation is used at the front end portion that will remain after partial cutting of the paper. It is good to form in a cutting surface other than the edge of the said binding origin side.

  According to the booklet of the present invention, the cover (front cover, back cover, spine cover) is used as a display area for displaying the product name, model number, logo, etc., and the cutting surface is also a new display area, as in the conventional booklet. Is possible. Since such a notation is formed by partially removing the cut surface by a non-contact removing means such as laser irradiation, there is no problem that the sheets adhere to each other or cause bleeding due to viscosity like ink. Both small and large marks can be clearly and reliably formed. In addition, when forming the notation on the cut surface, it is possible to perform processing by non-contact removal means such as laser irradiation on the cut surface in a state where a plurality of booklets are stacked and placed on a plurality of booklets. The notation can be formed at the same time, and the working space, efficiency, time and cost can be reduced.

  Further, according to the copy book of the present invention, the cut surface is colored by a non-contact removal means such as irradiating a laser beam on the cut surface based on structural factors in the carbonless copy book. Therefore, it can be erased without using a desensitizing agent or a decoloring agent. As a result, the cost and labor required to apply desensitizers and decolorizers can be saved, and there is no risk of inadvertent adhesion of decolorizers etc. to the necessary areas, while the cut surface is printed on paper. It will be possible to provide a copy book with the same color as the ground color.

  Embodiments of the present invention will be described below with reference to the drawings.

  First Embodiment This embodiment shown in FIG. 1 shows an example in which a carbonless copy book A used as a delivery slip is adopted as one form of a booklet. In the present embodiment, not only the display area 21P indicating the notation P such as the manufacturer / sales company name Pa, the product name Pb, the product number Pc, etc. is provided at an appropriate location on the front cover 21 of the copy book A, but also the cut surface 1X. Is also used as the display area 1Q.

  The copy book A includes an upper sheet 11, a middle sheet 12, and a lower sheet 13 in order from the top (sometimes referred to as “sheet 1” or “each sheet 11, 12, 13” for convenience of explanation). A plurality of sets of copy forms 1S composed of three sheets (not limited to 50 sets in this example) are stacked vertically, and the front cover 21 is placed above the uppermost upper paper 11 and the lowermost lower paper. The back cover 22 is respectively arranged on the lower side of the sheet 13, and the entire left end portion is bound with a binding tape 23 serving as a back cover with the binding end portion 1t as a binding end portion 1t. As shown in FIG. 3A, each of the papers 21, 22, and 23 has a horizontally long rectangular shape with substantially the same size, and the edges 11a, 12a, and 13a are aligned in a superposed state. It is in a state (see FIGS. 1 and 3B). Accordingly, the four cutting surfaces 1X of the copy book A composed of a bundle of the edges 11a, 12a, and 13a of the papers 11, 12, and 13 are all substantially flush. The front cover 21 and the back cover 22 have the same shape as the internal paper 1, and the edges 21a and 22a of the front cover 21 and the back cover 22 also constitute a part of the cut surface 1X.

  Each of the papers 11, 12, and 13 is made of a white-colored paper material. The main pieces 11A, 12A, and 13A each having a necessary information printed as a delivery slip are printed on each surface, and a margin on the side of the binding end 1t. 11B, 12B, 13B, and used book pieces 11A, 12A, 13A and blank portions 11B, 12B so that used book pieces 11A, 12A, 13A can be separated from the blank portions 11B, 12B, 13B. , 13B are formed with perforations 11C, 12C, 13C, respectively. That is, the blank portions 11B, 12B, and 13B correspond to remaining portions that remain without being separated in the copy book A. The front cover 21 and the back cover 22 are made of a paper material that is thicker than the paper 1. In particular, the surface of the front cover 21 is the name of the manufacturer / sales company Pa, product name Pb, product number of the copy book A. This is a normal display area 21P displaying a notation P such as Pc. Note that the back cover 22 and the binding tape 23 (back cover) may also be used as a normal display area.

  Here, a structure for copying in the copy book A of the present embodiment will be described. On the back surface of the upper paper 11, microcapsules (not shown) with a built-in color former are applied on the entire surface. A developer (not shown) that is in contact with the color former and exhibits a coloring reaction is coated on the entire surface of the intermediate paper 12. Similarly to the back surface of the upper paper 11, a color former built-in microcapsule (not shown) is applied to the entire back surface of the middle paper 12. Further, a developer (not shown) is coated on the entire surface of the lower sheet 13 in the same manner as the surface of the middle sheet 12. That is, when writing on the surface of the upper paper 11, the microcapsules on the back surface of the upper paper 11 and the back surface of the middle paper 12 are destroyed by the writing pressure, and the internal colorant flows out. In addition, the developer applied to the surface of the lower paper reacts so that the description of the upper paper 11 is copied to the middle paper 12 and the lower paper 13 in a predetermined color (usually blue or black).

  Such a copy book A is manufactured by the following process. First, a winding base paper (not shown) is prepared in a state where each paper 11, 12, 13 is wound into a dedicated roll. The winding base paper for the upper paper 11 is previously coated with a color former-containing microcapsule on the back surface. The winding base paper for the medium paper 12 is preliminarily coated with a developer on the front surface and a microcapsule with a color developer on the back surface. A developer is coated on the surface of the winding base paper for the lower paper 13. Then, after printing necessary items such as ruled lines, characters, symbols, etc. on the surface of each of the winding base papers, each end of the three winding base papers is pulled out and stacked in three sheets for each predetermined length. Cut. Here, the roll-shaped winding base paper cut into a sheet is called an upper paper base, a middle paper base, and a lower paper base. These upper paper and middle paper The base paper for lower paper is called a set of base paper. Here, FIG. 2 particularly shows the upper paper base 31. In the present embodiment, nine sheets of upper paper 11, middle paper 12, and lower paper 13 can be cut out from each base paper (3 vertical sheets and 3 horizontal sheets). Each base paper is pre-formed with perforations that become the perforations 11C, 12C, and 13C of each paper after cutting. FIG. 2 shows a perforation 31 </ b> C formed on the upper paper base 31. A plurality of such base paper sets are stacked on top and bottom (in the case of this embodiment, 50 sets), and further, the top cover base paper 31 is placed on the top top base paper 31 and the bottom bottom base paper As shown in FIG. 2, a cutting machine blade is inserted along the cutting line 31a as shown by the alternate long and short dash line in FIG. 2, and a total of nine sets of 50 copies of copy forms 1S are obtained. . In such a cut state, the microcapsules coated on the back surface of the upper paper 11 and the back surface of the middle paper 12 are destroyed by the external force received from the cutting edge of the cutting machine, and the internal colorant flows out, and the color is generated. The agent reacts with the developer coated on the surface of the middle paper 12 and the surface of the lower paper 13, respectively, and color appears on the edge 12a of the middle paper 12 and the edge 13a of the lower paper 13 (FIG. 3 (a)). As the cutting pressure acts so as to gradually decrease from the edge side toward the inside of the paper 1, this color development is darkest at the edge edges 12a and 13a and gradually appears lightly toward the inside. However, although color is not generated at the edge 11a of the upper sheet 11, the result of color development at the respective edges 12a and 13a of the middle sheet 12 and the lower sheet 13 occupying 2/3 of the total number of sheets is shown in FIG. As shown in FIG. 5, the entire copy book A is colored on the cut surface 1X, which is a set of the edges 11a, 12a, and 13a of the sheets 11, 12, and 13. As shown in FIG. 1 and FIG. 3B, a copy of the copy form group 1S is bound to the bundle of copy forms 1S using the front cover 21, back cover 22, and binding tape 23 to obtain a completed copy book A. I am going to do that. Therefore, the front cover 21 and the back cover 22 are already arranged at the time of cutting, and before proceeding to the next step, the binding tape 33 is wound around the binding source end 1t to finish the bookbinding. The process up to this point is the same as the conventional copy book manufacturing process. The copy book A is not limited to the above-described procedure, and the cutting tape 23 is cut in a state where, for example, the cutting line 31a as shown in FIG. 2 is cut along four cutting lines in the vertical direction. It can also be obtained by a procedure of winding on the surface side and then cutting along the transverse cutting lines (four).

In this way, in the present embodiment, the copy surface A in which coloring occurs on the cutting surface 1X is irradiated with the laser light L on the three cutting surfaces 1X excluding the cutting surface on the side of the binding source end 1t. 1X is used as a display area 1Q displaying a notation Q such as a manufacturer / sales company name Qa, a product name Qb, and a product number Qc. This laser beam L is applied as an example of a non-contact removing means for removing the cut surface 1X of the copy book A in a non-contact manner. That is, as shown in FIG. 4, a plurality of copy books A (six copy books in the illustrated example, but may be more or less) may be placed on a pedestal (not shown) and stacked. The cut surfaces 1X are aligned vertically. Then, the laser beam L is irradiated on the aligned cut surfaces 1X so as to draw predetermined characters, figures, patterns, and the like from the laser irradiator LM. As a result, the material constituting the cut surface 1X (paper, the reaction product of the color developer and developer impregnated in the paper, the unreacted color developer and the microcapsule and the developer) is sublimated or evaporated to scrape off and the cut surface Form the notation Q on 1X. More specifically, at the part irradiated with laser light on the cutting surface 1X, the material itself disappears as a result of being exposed to high heat instantaneously, so that the cross section of the paper 11, 12, 13 is exposed, and the background color of the paper 1 The notation Q is formed by the contrast with the colored cut surface 1X around it. In order to form the notation Q, during irradiation of the laser beam L, either the laser irradiator LM or the mount on which the copy book A is placed is moved up and down and left and right as appropriate. Further, as the laser beam L, an appropriate type of laser beam may be used with an appropriate intensity. However, the light is instantly evaporated from the edges 11a, 12a, and 13a to the inside of the paper, and the irradiated paper is irradiated. In this embodiment, a CO ₂ laser is used in consideration of the advantage of not changing the color. In the present embodiment, a laser irradiation device manufactured by Keyence Corporation (product number ML-9100) is used as the laser irradiator LM with an output of 30 W. However, any laser irradiation device of this type may be used. can do.

  Here, in the present embodiment, the notation Q as described above is added to the portions corresponding to the main pieces 11A, 12A, and 13A of the papers 11, 12, and 13 in the cutting surface 1X, as well as the blank portions 11B, 12B, A product name “delivery note” Qd is also formed as a part of the notation Q at a location corresponding to 13B. In this way, as shown in FIG. 5, when the used pieces 11A, 12A, 13A are separated from the blank portions 11B, 12B, 13B, they correspond to the pieces 11A, 12A, 13A of the cutting surface 1X. Although the notations Qa, Qb, and Qc are gradually missing at the part, the part of the cut surface 1X where the binding tape 23 is not wound at the binding source end 1t of the copy book A can also be used as the display area 1Q. Therefore, the notation Qd remains even if the main pieces 11A, 12A, and 13A are separated, and the notation Qd can be kept until the copy book A is used.

  As described above, the copy book A of the present embodiment not only uses the cover (front cover 21) as the display area 21P for displaying the notation P such as the manufacturer / sales company name Pa, the product name Pb, and the product number Pd, but also cuts the cover. The surface 1X is also used as the display area 1Q. In order to form the notation 1Q on the cutting surface 1X, the laser beam L is irradiated as non-contact removing means for partially removing the cutting surface 1X in a non-contact manner. Specifically, when the copy book A is manufactured, the color of the cut surface 1X generated due to structural factors necessary for copying is erased, that is, a plurality of base papers 31 and the like are cut to overlap the upper paper 11, the middle paper 12, When the lower paper 13 is made, the color of the cut surface generated as a result of the reaction between the color former applied to each of the papers 11, 12, and 13 and the developer by the cutting pressure is determined for each material of the paper 1. The ground color of the paper 1 is exposed by partially removing the laser light L in a non-contact manner.

  Therefore, in the past, efforts have been made to erase the color on the cut surface of the copy book by applying a desensitizing agent or a decoloring agent. However, by using such color development on the other hand, a laser is applied to the colored cut surface 1X. The cutting surface 1X can be effectively used as a new display area 1Q that has not been used in the past due to the contrast between the background color of the paper and the developed color in the part removed by irradiating the light L. As a result, the use of a relatively expensive desensitizer or the like can be completely stopped. Further, by forming the notation Q on the cut surface 1X, the notation Q on the cut surface 1X can be seen by the user even when the copy book A is placed on a shelf, drawer, etc. without the notation P on the front cover 21 being visible. Therefore, the convenience when using the copy book A is also improved.

  In the present embodiment, since the laser light L is used as the non-contact removing means, the notation Q consisting of fine characters, figures, patterns and the like can be drawn on the cut surface. In this way, when the notation Q is formed on the cut surface 1X, unlike the case where the notation P is printed on the surface of the cover (front cover 21 or the like), a plurality of copy books A are stacked as in the above-described work example. Since the cut surface 1X can be irradiated with the laser light L as a state or as a state in which a plurality of copy books A are arranged upright, the notation Q on the cut surface 1X with respect to the plurality of copy books A It is possible to perform the forming process all at once. Further, the cut surface 1X of the copy book A includes not only the book pieces 11A, 12A and 13A which are separated after use, but also the copy book A after the used book pieces 11A, 12A and 13A are cut off. Since the notation Qd is also formed in the remaining blank portions 11B, 12B and 13B, the notation Q can be left until the copy book A is used up.

  In the first embodiment described above, an example in which the notation Q on the cutting surface 1X is formed by irradiating the portion corresponding to the character, symbol, pattern, etc. constituting the notation Q with the laser beam L is shown. However, for example, as in the copy book A ′ shown in FIG. 6, a portion other than the portion to be represented as Q ′ (Q′a, Q′b, Q′c, Q′d) in the colored cut surface 1X. Even when the laser beam L is irradiated to the mark Q ′, the notation Q ′ can be formed. That is, in the notation Q ′ part, the color development (for example, blue or black) generated by the reaction between the color former and the developer is left by the cutting pressure, and the color development is performed with the laser light L for each material for the other portions. Even when the ground color (for example, white) of the paper 11, 12, 13 is exposed by sublimation or evaporation, the contrast between the portion irradiated with the laser light L and the portion not irradiated on the cutting surface 1X is clear. Thus, the cut surface 1X can be used as the display area 1Q ′.

  Second Embodiment The present invention is not limited to the copy books A and A ′ as described above. For example, the second embodiment shown in FIG. 7 illustrates a journal B that is a kind of book. This journal B is a stack of a plurality of white-colored papers 100 printed on the surface with items that can be used as ordinary journals, and one edge thereof is bound with a cover 200. Accordingly, a gold foil 100g is applied to the edge 100a (excluding the binding-side edge) of each paper 100. Although not shown, the paper 100, which is the contents of the journal 1, is also formed by cutting a large number of base papers in the same manner as the copy book A of the above embodiment.

  As shown in the figure, on the cover of this journal B (front cover 200), as an example, the notation P ″ of the product name “journal book” is printed. On the other hand, the letter “Q” of the “journal book” as the product name is also applied to the cut surface 100X coated with the gold foil 100g except the cut surface on the binding source side among the cut surfaces that are a set of the edges 100a of the paper 100. a and a user name (○ △ Co., Ltd.) Q ″ b. That is, the journal B of the present embodiment not only has the cover (front cover 200) as the display area 200P but also the cut surface 100X as the display area 100Q.

  Such a notation Q ″ on the cut surface 100X is formed in the same manner as in the first embodiment. That is, after applying the gold foil 100g to the edge 100a of the paper 100, the cutting surfaces 100X are aligned in a state where a plurality of journals B are stacked or arranged side by side, and the notation Q '' is expressed with respect to these cutting surfaces 100X. By irradiating the laser beam L so as to draw, the gold foil 100g or the gold foil 100g at the irradiated portion and the material of the paper 100X are sublimated to expose the ground color in the cross section of the paper 100.

  By doing in this way, since the part without the gold foil 100g can be formed as the notation Q ″ in the cutting surface 100X coated with the gold foil 100g over the entire surface, the booklet having the display area 100Q also provided on the cutting surface 100X. The journal B can be obtained. In this case, the product value is not limited to simply increasing the product value by simply attaching the gold foil 100g to the cut surface 100X, and the product value can be further improved as the display area 100Q. Can be planned. In addition, although common to the first embodiment, the user name Q ″ b of the booklet can be applied as the notation Q ″ formed by the irradiation of the laser beam L, so a new name that has not existed in the past. It is also possible to develop products as a service. In the above example, the cutting surface 100X is coated with 100 g of gold foil, but the same applies to the case where ink of a color different from the ground color of the paper 100 is coated instead of the gold foil 100 g. A booklet with added value can be created. Note that, as in the modification of the first embodiment, the portion of the cut surface 100X other than the portion where the notation is to be formed is irradiated with the laser light L to expose the ground color of the paper 100, and the portion where the gold foil 100g remains is indicated. It is also possible.

  Furthermore, the notation formed on the cut surface is not limited to a fixed shape such as a character or a figure. For example, the modified example shown in FIG. 8 is a sales book B ′, which is a kind of book as an example of a booklet. In this example, a gold foil {or { Colored ink (color different from the paper)} 100 g is applied to the cut surface (excluding the cut surface on the binding side) 100′X composed of a set of edges 100′a of the paper 100 ′. , A notation Q ′ ″ composed of an irregular pattern (for example, a marble pattern) is formed. Such a notation Q ′ ″ can be formed by appropriately changing the output of the laser beam L when the cutting surface 100′X is irradiated with the laser beam L. That is, a change appears in the depth of the gold foil 100g or the ink of the edge 100′a of the paper 100 ′ or the material of the paper 100 ′, which is removed by the intensity of the output of the laser light L. The notation Q ′ ″ is formed. If it is such, it is possible to create a booklet having a cutting surface 100′X that is innovative in terms of design, and also to prevent tampering by partially removing the paper (page) 100 ′. Can do. In addition, as a conventional booklet having an appearance similar to this example, one in which ink is coated with a marble pattern on the cut surface is known, but in this example, a gold foil 100 g pre-coated on the edge of the paper or Since the ink or the material of the paper and the paper are removed by the irradiation of the laser beam L, the trouble that the papers stacked due to the adhesiveness of the ink stick to each other and cause trouble in turning the page is eliminated. be able to.

  Third Embodiment The present embodiment shown in FIG. 9 is a carbonless copy book A ″ similar to the first embodiment. That is, as shown in FIG. 3B, when the paper 1 (upper paper 11, middle paper 12, lower paper 13) is cut out from the base paper 31 or the like, it is applied to the back surfaces of the upper paper 11 and the middle paper 12. The microcapsule is destroyed by the cutting pressure, and the color developer inside the microcapsule flows out and reacts with the developer applied on the surface of the middle sheet 12 and the lower sheet 13, thereby causing color development on the cut surface 1X. is there. Note that the present embodiment is the same as the first embodiment except for the processing for the cut surface 1X of the copy book A ″, and a description thereof will be omitted.

  In this embodiment, all the coloring on the cutting surface 1X is erased to expose the ground colors of the papers 21, 22, and 23, and a copy book A ″ having a beautiful cutting surface 1X with no coloring is obtained. That is, in the first embodiment, when the cutting surface 1X is irradiated with the laser beam L as shown in FIG. 4, the laser beam L is irradiated so as to draw characters and figures, and the notation Q is formed. In the case of the form, the laser beam L is irradiated to the entire cut surface (excluding the cut surface on the binding side) 1X. In this way, the color of the cut surface 1X is sublimated with the material (paper, microcapsule, color developer, developer, and the reaction product of the color developer and developer) with the instantaneous heat of the laser beam L. Alternatively, since the ground color in the cross section of the paper 1 is exposed across the front surface of the cutting surface 1X by evaporating, the cutting surface 1X has the same color as the front and back surfaces of each paper 11, 12, 13 and the cutting surface 1X is colored. There can be no beautiful and good looking condition.

  In the case of the copy book A ″ in which the color of the cut surface 1X is erased as described above, it is not necessary to apply a desensitizer or decolorant to the cut surface as in the conventional copy book. It is possible to reduce the cost required for the purchase and application. Of course, by not using a desensitizing agent or the like, it is possible to eliminate the possibility of color development adhering to the surface of the paper 1 that is originally required, so it is possible to reduce product defects. Further, on the cut surface 1X where the color development has disappeared by the irradiation of the laser beam L, the color former (and microcapsule) and the developer previously applied to the paper 11, 12, 13 are also sublimated or evaporated. Even if a pressure is applied afterwards by hitting the cut surface 1X with no contact, for example, there is also a merit that no new color can be generated at that portion.

In addition, this invention is not restricted to each embodiment mentioned above, It is possible to apply to the booklet of all aspects. For example, the cut surface originally exhibits the background color of the paper, but the color or pattern is printed on the front or back surface along the edge of the paper for headlines, etc. For a booklet such as a dictionary or catalog that can be seen on the cut surface side by seeing through the paper, it is also possible to form a notation by irradiating a portion of the cut surface where the printing is visible with laser light. is there. Further, in the above example, a mode in which laser light is used as a non-contact removing unit for forming a notation on the cut surface or erasing all coloring on the cut surface has been described. In addition, powerful visible light, ultraviolet light, infrared light, and the like can be applied. Even when laser light is applied, other general laser light can be used as appropriate without being limited to the CO ₂ laser.

  In addition, the specific configuration of each part is not limited to the above-described embodiments or modifications thereof, and various modifications can be made without departing from the spirit of the present invention.
