New description: [New technical field] This creation is related to the kind of _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Covert postcards such as personal information. For example, the front is the recipient's name shed for the postcard that sends the credit, and the back is the first piece of the credit card content. In addition, the front is the content of the letter of credit, and the back is the second (four) of the name of the trust letter. In addition, the front and back sides are coated with a tear-off adhesive sheet. These techniques are described in Patent Document 2, in which Patent Document 1 is a Japanese Utility Model Registration No. 3138〇14. s has been included in this special technology, as the front side of the first piece of paper and the front side of the second piece of paper are displayed in the form of two sheets of paper #, three folds are made to send letters to use Ming W. In addition, after the postcard used as the credit card is unfolded, the back of the first paper call > and the back side of the second paper sheet are attached in three paper shapes, and then folded back into a credit postcard. <Problems to be Solved by Patent Document 1> However, the technique described in the above patent document is to form a postcard by folding two sheets of paper, and to make the folded portion thicker, especially to make 6 layers. The above postcard thickness paper will be difficult.

[Embodiment] 4 M3 64003 <First Embodiment> FIG. 1A is a perspective view showing a covert postcard 1 according to a first embodiment. Fig. 1B is an enlarged view of an X portion of Fig. ία. In addition, FIG. 3 is a plan view in which the concealed postcard 1 is unfolded, and FIG. 3 is a reverse view in which the concealed postcard 1 is unfolded. The fold lines 31-35 of the sheet of paper 10 of Fig. 4 have a state in which a broken line is indicated. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Adhesive 2〇 is then bonded. Here, in the present embodiment, the peelable adhesive 2G which can be repeatedly pasted is made of a known material. As an example of the known tear-off adhesive, it is disclosed in Adhesive No. 11-28_. Further, the tearable adhesive 20 is not viscous in the general state, but the bonding between the adhesives is silky, and the material properties can be torn again after the adhesion. Therefore, although it is shown in the drawings that the adhesive 2 can be torn open, in fact, because it is a sheet of paper, she is substantially thin. Further, the paper sheet 1G of the present embodiment is constituted by a paper having a thickness of six postcards arranged in a straight line. This piece of paper 1M6 has its own self-prepared front _ 丨, and some paper pieces called (four) borders have a fold line - yeah. There is also a postcard called "3" used as a postcard for sending credits, and a postcard for returning credits. Broken) Again, it is preferable to form a dotted row of holes on the paper 1H3 and the back boundary portion 33 of the credit. In this way, if the fold line ^ 5 M364003 is in the shape of a dotted line, it can be easily torn. Paper for credit card>;11-13 and paper sheet for returning credits 14-16 As described above, the side of any sheet of paper 1 Η 6 which can be peeled off the adhesive agent 蒲 u π μ #片10 is adjacent to the side of the sheet to enable The way to tear it is glued. Specifically, as shown in FIG. 4, <;:} Μ j 1D ^ ' 口, , , the back surface 11B of the sheet 11 and the back surface 12B of the paper sheet 12 are intertwined with the adhesive 2〇 to crimp. The same front surface 12A is in contact with the front surface m of the paper sheet 13, and the front surface (10) of the paper sheet 14 and the front surface 15A of the paper sheet 15 are crimped. The back side 158 of the sheet 15 and the back side 16B of the sheet 16 are crimped. Further, the back surface 13B of the 'paper> Π 3 and the # ΐ 4β of the paper sheet 14 are not pressure-bonded, for example, in order to record the address of the addressee on the back surface 14β of the paper sheet 14 as a reply postcard cover. According to the above, the crimped object surface is coated with a peelable adhesive 2 制作, and the six sheets 11-16 become the open and rewritable moonlight, and can be thinly stacked. -body. 8m拉。 The thickness of the paper sheet having a thickness of about 0. 8mra. However, the front surface UA of the paper sheet 14 and the front surface 15A of the paper sheet 15 are adhered by the tear-off adhesive 20, and the back surface 15B of the paper sheet 15 and the back © 16B' of the paper sheet 16 are adhered by the tearable adhesive 20. It is better to repeat the adhesive to peel the adhesive. If the adhesive of Huixinlin 14-16 is a re-stickable adhesive 20 that can be repeatedly applied, the replyer can make the tearable adhesive 20 complicated. Reduce the burden on. As described above, the "hidden sheet" 1 and any sheet of paper constituting the sheet of paper are bonded to one side of the adjacent sheet by a pressing method. As in the embodiment, M364003 overlaps the six sheets 11-16. It is also possible to reduce the thickness. Therefore, six or more pieces of paper sheets 11-16 having a thickness of the letter sheet are used to form a sheet of paper sheet 10, and a cover sheet 1 which is thin enough can be manufactured. Also, in a covert postcard 1, more information than before can be written in the covert postcard 1. <Second Embodiment> Fig. 5A is a perspective view of a covert postcard 2 according to a second embodiment. Fig. 5B is an enlarged view of a portion Y of Fig. 5A. 6 is a front view showing the unfolded state of the concealed postcard 2, and FIG. 7 is a rear view showing the state in which the concealed postcard 2 is unfolded. As shown in FIGS. 6 and 7, the concealed postcard 2 of the second embodiment is such that the short side length si of the paper sheet ill placed on one side of the paper sheet 100 is shorter than the short side length S2-S6 of the other paper sheets 112-116. It has the same structure as the covert postcard 2 of the first embodiment. Therefore, the repeated explanation is omitted. The paper sheet 100 of the present embodiment is formed by stacking six sheets of postcard-thick paper sheets 111-116. The sheets 111-116 each have a front surface 111A_116A φ and a back surface U1B-116B. The boundaries of these sheets 111-116 have fold lines 131-135. Further, as shown in Figs. 5A and 5B, the covert postcard 2 of the present embodiment has a gap between the short side length S1 of the paper sheet 111 placed on one side of the paper sheet 100 and the short length S2-S6 of the other paper sheets 112-116, so that the adjacent A portion of the edge of the sheet ία of the sheet becomes the exposed portion 140. In the present embodiment, at least a part of the exposed portion 140 of the sheet placed on the side of the sheet of paper is used as the indicator portion 141 for tearing the starting point. M364003 Further, in the present embodiment, the exposed portion 14 is used to guide the sheet m' on the side of the sheet (10), but is not limited thereto. This portion of the exposed portion (10) is a gap between the formed sheet 111 and the sheet 112, and a sheet of paper having a thickness of about 13 is thin, and the human touch can be felt. Therefore, the starting point of the tearing can be felt without depending on the above-described indicator portion 141. _ is the full width of the long side of the paper sheet 111 as the starting point of tearing, and the convenience of the tearer is improved compared with the hidden Φ postcard with only four corners having a tearing starting point. . In the present embodiment, the aforementioned width 'in other words, the difference between the short side length S1 of the sheet m and the short side length S2-S6 of the other sheets 112_116 is 5 mm. This gap will be good from the operability of the tearing and the roundness of the mark. However, if the excessive exposure of the part 14〇 is widened, the above-mentioned gap will be better because there is no need to record the necessary information such as the addressee. Of course, in the concealed postcard 2 of the present embodiment, the indicator portion 141 is displayed in the exposed portion #140 of the sheet (1), so that the tearer can tear the sheet (1) at the beginning of the sheet and can be easily seen. That is, the visual communication is most effective, and the indicator portion 141 can achieve the maximum effect. Further, in the sign portion 1, it is only used as a tearing start point for guiding the sheet (1), and a distinctive pattern or character such as an advertisement can be merged. The existence of this corporate advertisement can strongly mean the tearing position of the tearer. However, this concealed postcard and the first embodiment of the concealed postcard " the same/, the thickness of the sheet of paper 1H_116 is also sufficient to make a thin concealed postcard. M364003 In addition, if it is a hidden postcard in the past, it is necessary to record a lot of information, and it is necessary to use it as an exposed part. However, in the case of the covert postcard 2 of the present embodiment, even if it is indicated in (4) and FIG. 5β, the long side of the sheet (1) is exposed at 4 minutes and 14G to form a sufficient width, and the advertisement can be sufficiently ensured compared with the conventional concealed postcard. The series reported the silk circumference. Therefore, in the fourth embodiment, it is very easy to simultaneously tear the covert postcard 2 and ensure the range of the amount of information. • <Third Embodiment> Fig. A8 is a perspective view of the concealed postcard 3 of the third embodiment. Fig. 8B is an enlarged view of a portion Z of Fig. 8A. In addition, Fig. 9 is a perspective view of the back side of the concealed postcard 3. Also, '® 1〇 is a front view showing the unfolded postcard 3 unfolded, and the figure U 疋 will hide the rear view of the unfolded state of the clear piece 3. In the concealed postcard 3 relating to the third embodiment, the lengths τι and T6 of the paper 211 and the short side of the paper 216 are placed on both sides of the paper sheet 2, and the lengths of the other sheets 212-215 are shorter than T2 to T5. If it is not seen, there is a structure of the covert postcard 2 related to the second embodiment. Therefore, the repeated explanation is omitted. The paper sheet 200 of the present embodiment is constituted by sheets 211-216 of six postcard thicknesses connected thereto. The sheets 211-216 each have a front side 211 Α - 216 Α and a back side 211 Β - 216 。. The boundaries of these sheets 211-216 have fold lines 231-235. Further, the hidden postcard 3' is as shown in Figs. 8A and 8B, and the paper sheet 200 has a gap between the short side length τ of the sheet 211 and the short side length Τ2-Τ5 of the other sheets 212-216, and An edge portion of the sheet 212 adjacent to the sheet 211 exposes a portion of the exposed portion 240 of the M364003. In the present embodiment, at least a part of the paper sheet portion 24G is exposed as the starting point of the tearing of the sheet 211. The present embodiment is placed on the sheet P 241 as shown in Fig. 9 . The edge of the sheet 216 has a short side length of 6 and other sheets 211 to 215. The short side sheet has a gap, and the edge of the sheet 215 adjacent to the sheet 216 has a T5 of 250. In the present embodiment, the portion of the sheet that is placed on the edge of the paper sheet is at least the portion of the portion of the sheet that is used as the starting point for tearing. The exposed postcard 3 of the present embodiment is on the sheet 211. . The exposed sign portion 241 '' so the tearer can be quite:::. Torn the starting point inside. The exiting sheet 211 can be seen very easily by the tearer and the concealed postcard 3 has the indicator portion 251, and the sheet 216 is torn open. Further, in each of the above embodiments, each of the sheets is bonded by a pressing method, and is not limited thereto. Other recognized adhesion methods have also turned. However, it is preferable to form the paper sheet #f into six layers and bond them in a pressing manner. In addition, in the above embodiments, the mailing and returning reward tablets are taken as an example, but the secret is not limited. For example, in the first embodiment, when the back surface 13B of the paper sheet 13 and the back surface 14B of the paper sheet 14 are pressure-bonded, all of the six paper sheets 11-16 can be thinned and integrated. In the above, each of the above embodiments is described as a sheet of paper composed of six sheets of paper, but is not limited thereto. Paper sheets with seven or more sheets of paper attached can have the same effect. As described above, there are also special examples within the scope of the present invention, and also include the scope of application of the present patent.
