This content forming unit 55 bends a plurality of collated content papers P1 (hereinafter, appropriately referred to as content papers P1) sent out from the collating unit 51 to form the content B. And the specific configuration of the content forming unit 55 is as follows.

[0028] A main folding roller 57 is rotatably provided on the outlet side (downstream side) of the collating unit 51 in the device housing 41. At a position adjacent to the main folding roller 57 in the device housing 41, an introduction roller 59 that cooperates with the main folding roller 57 to introduce the content paper P1 from the content paper conveyance path 45 is rotatably provided. Also, a guide plate 61 for guiding the content paper P1 introduced by the main folding roller 57 and the introduction roller 59 is provided below the main folding roller 57 in the device housing 41. Further, the guide plate 61 is provided with a butting member 63 that abuts against the tip of the content paper P1 to give slack near the folding line P1a of the content paper P1, and this butting member 63 is position adjustable along the guide plate 61 by driving an appropriate first position adjustment motor (not shown). And an intermediate roller 65 is rotatably provided at a position adjacent to the main folding roller 57 and facing the introduction roller 59 in the device housing 41. This intermediate roller 65 bends the content paper P1 from the folding line P1a in cooperation with the main folding roller 57 with the vicinity of the folding line P1a of the content paper P1 in a slack state.

[0029] On the left side of the main folding roller 57 in the device housing 41, facing the drawing, a guide plate 67 for guiding the content paper P1 folded by the main folding roller 57 and the intermediate roller 65 is provided.

Furthermore, a delivery roller 71 is rotatably provided at a position adjacent to the main folding roller 57 and facing the intermediate roller 65 in the device housing 41. This delivery roller 71 cooperates with the main folding roller 57 with the folding line P1b of the content paper P1 slackened to fold the content paper P1 from the folding line P1b while guiding it to the content paper conveyance path 45 side.

[0030] A front folding portion 73 is provided at the confluence of the content paper conveyance path 45 and the envelope paper conveyance path 47, and this front folding portion 73 folds the printed envelope paper P2 (hereinafter, appropriately referred to as the envelope paper P2) sent out from the connection conveyance path 35. And the specific configuration of the front folding portion 73 is as follows.

[0031] A main folding roller 75 is rotatably provided at the confluence of the content paper conveyance path 45 and the envelope paper conveyance path 47, and at a position adjacent to the main folding roller 75 in the device housing 41, an introduction roller 77 that cooperates with the main folding roller 75 to introduce the envelope paper P2 from the envelope paper conveyance path 47 is rotatably provided.

[0032] Also, below the main folding roller 75 in the apparatus housing 41, a guide plate 79 for guiding the envelope paper P2 introduced by the main folding roller 75 and the introduction roller 77 is provided. Further, the guide plate 79 is provided with an abutting member 81 that abuts against the leading end of the envelope paper P2 to give slack in the vicinity of the folding line P2a of the envelope paper P2, and this abutting member 81 is position-adjustable along the guide plate 79 by driving an appropriate third position adjustment motor (not shown). And at a position adjacent to the main folding roller 75 and facing the introduction roller 77 in the apparatus housing 41, a delivery roller 83 is rotatably provided.

[0033] This delivery roller 83 bends the envelope paper P2 from the folding line P2a while nipping the envelope paper P2 with a predetermined pressure with the main folding roller 75 in a state where the vicinity of the folding line P2a of the envelope paper P2 is slackened, and while enclosing the content B conveyed by the conveying roller 72, it sends it out toward the envelope forming portion 85. The main folding roller 75 and the delivery roller 83 have a rotating shaft (not shown) and a grip portion (not shown) fixed to this rotating shaft and nipping the folded content between the envelope papers from above and below. This grip portion is continuously provided in the direction of the rotating shaft in order to nip the folded content B and the envelope paper P2 and bend the envelope paper P2. The main folding roller 75 and the delivery roller 83 are collectively referred to as the envelope folding roller.

[0034] On the downstream side of the front folding portion 73, conveying rollers 74, 76 for sending out the envelope paper P2 into which the content B is enclosed toward the envelope forming portion 85 are provided, and these conveying rollers 74, 76 are configured as a pair of rollers including a driving roller that is rotationally driven by driving a driving motor (not shown) and a driven roller that rotates by the rotational driving of the driving roller.

[0035] Furthermore, on the downstream side of the front folding portion 73, an envelope forming portion 85 is provided, and this envelope forming portion 85 forms the envelope E by folding the envelope paper P2 sent out from the front folding portion 73. And the specific configuration of the envelope forming portion 85 is as follows.

[0036] On the outlet side (downstream side) of the front folding part 73 in the apparatus housing 41, a main folding roller 87 is rotatably provided. Adjacent to the main folding roller 87 in the apparatus housing 41, an introduction roller 89 that cooperates with the main folding roller 87 to introduce the envelope paper P2 from the envelope paper conveyance path 47 is rotatably provided.

[0037] Also, below the main folding roller 87 in the apparatus housing 41, a guide plate 91 for guiding the envelope paper P2 introduced by the main folding roller 87 and the introduction roller 89 is provided. Further, on the guide plate 91, a butting member 93 that abuts against the tip of the envelope paper P2 (and gives slack to the vicinity of the folding line P2b of the envelope paper P2) is provided. This butting member 93 is position-adjustable along the guide plate 91 by driving an appropriate fourth position adjustment motor (not shown). Also, along the guide plate 91, in the vicinity of the butting member 93, a water adding mechanism 99 for applying water to an adhesive coating part where the water-based paste of the envelope paper P2 described later is applied is provided.

[0038] And at a position adjacent to the main folding roller 87 and facing the introduction roller 89 in the apparatus housing 41, a final folding roller 95 is rotatably provided. This final folding roller 95 folds the envelope paper P2 from the folding line P2b in cooperation with the main folding roller 87 with the vicinity of the folding line P2b of the envelope paper P2 in a slack state.

[0039] Downstream of the filled envelope conveyance path 49, a sealing part 86 is provided. This sealing part 86 seals the envelope E sent out from the envelope forming part 85. Also, the sealing part 86 includes a pair of sealing rollers 88 that sandwich and press the envelope E. This pair of sealing rollers 88 is rotatable by driving an appropriate sealing motor (not shown). Here, the envelope E is sealed by the adhesive action of a pressure-sensitive adhesive previously applied to the envelope paper P2 when it is sandwiched and pressed by the pair of sealing rollers 88.

[0040] Further, a sealed letter discharging unit 92 for discharging the sealed letter M that has been normally sealed and sent out from the sealed envelope conveying path 49 is provided on the downstream side of the sealed envelope conveying path 49.

[0041] Next, the envelope paper P2 used in this embodiment will be described. FIG. 3A is an explanatory diagram showing a first example of the envelope paper P2 used when forming an envelope with the envelope sealing device 5 shown in FIGS. 1 and 2, and FIG. 3B is an explanatory diagram showing the envelope paper P2 after printing. FIG. 4 is an explanatory diagram showing a state in which the envelope paper P2 is folded into three to form the sealed letter M.

[0042] As shown in FIG. 3A, the envelope paper P2 is composed of a single sheet of paper and includes a first constituent paper 101, a second constituent paper 102, and a flap portion 103. The portion between the flap portion 103 and the first constituent paper 101 is a bending portion L1, and the portion between the first constituent paper 101 and the second constituent paper 102 is a bending portion L2.

[0043] By printing the envelope paper P2 shown in FIG. 3A with the above-described image forming apparatus 3, for example, as shown in FIG. 3B, the characters "admission ticket" are printed. A rectangular cutout region R1 is formed in the first constituent paper 101 and the second constituent paper 102. The periphery of the cutout region R1 is a cut line L3, and the user can easily separate the cutout region R1 from the envelope paper P2 by means of the cut line L3.

[0044] In the cutout region R1, for example, an admission ticket for entering a specific venue is formed. A rectangular RFID tag D1 is attached to the admission ticket. Desired information is written in the RFID tag D1, and the internal information can be read by bringing a reading device close to it. Further, an antenna portion D1a formed at the center of the RFID tag D1 is formed on the bending portion L2.

[0045] By placing the envelope paper P2 shown in Fig. 3A on the envelope paper feeding unit 23 of the encapsulation and sealing device 5 shown in Figs. 1 and 2 and executing printing, desired characters and names can be printed on the envelope paper P2 as shown in Fig. 3B. For example, characters such as "admission ticket", "academic year", and "name" are printed. Further, the envelope paper P2 is bent at the bending portion L2 so that the cutting area R1 is on the inside, and further bent at the bending portion L1, and adhered with a pressure-sensitive adhesive (not shown), so that, as shown in Fig. 4, a triple-folded sealed letter M can be formed.

[0046] As described above, since the antenna portion D1a formed on the RFID tag D1 is formed on the bending portion L2, when the envelope paper P2 is bent to seal the sealed letter M, the RFID tag D1 is in a state of being bent in two. For this reason, the sensitivity of the RFID tag D1 decreases, making skimming using a reading device or the like difficult, and leakage of information written in the RFID tag D1 can be avoided.

[0047] Also, when the user who has received the sealed letter M opens the sealed letter M and flattens the envelope paper P2, the antenna portion D1a returns to its normal state (a state where it is not folded), so normal communication becomes possible. Therefore, when the user who has received the sealed letter M opens the sealed letter M and further cuts off the above-described cutting line L3 to separate the admission ticket, communication using the RFID tag D1 provided on the admission ticket becomes possible.

[0048] In the examples shown in Figs. 3A, 3B, and 4, the RFID tag D1 is configured to be attached to the envelope paper P2. However, as shown in Fig. 5, the RFID tag D1 may be attached to the content paper P1 inserted into the envelope as an admission ticket. By folding the content paper P1 into a triple-fold at the bending portions L4 and L5 and inserting the content paper P1 into the envelope as shown in Fig. 6, the antenna portion D1a of the RFID tag D1 can be configured to be bent.

[0049] In this case, the content paper P1 with the RFID tag D1 attached is stored in the paper feed tray 17 shown in FIG. 2, desired characters are printed on this content paper P1, and it may be folded into three and enclosed and sealed in an envelope. When attaching the RFID tag D1 to the content paper P1, since the sealed letter M becomes invisible from the outside when sealed, the RFID tag D1 may be attached to either the front or back surface of the content paper. It is better to use them appropriately depending on the printed content.

[0050] FIG. 7 is an explanatory diagram showing an example of folding a plurality of (here, two) content papers P1A and P1B and sealing them in an envelope. As shown in FIG. 7, when attaching the RFID tag D1 to any one of the plurality of content papers P1A and P1B, if the RFID tag D1 is attached to the content paper on the outside of the three-fold, the bending of the antenna portion D1a is reduced when folded, and after opening, the RFID tag D1 can be easily returned to its original state, preventing deterioration of communication performance.

[0051] In this way, the sealed letter M of the first embodiment can be created using the enclosing and sealing device 5 according to this embodiment. Before the sealed letter M according to the first embodiment is opened, the communication sensitivity can be lowered because the antenna portion D1a of the RFID tag D1 is bent. Therefore, when the RFID tag D1 is present in the sealed letter M, it can be prevented from being skimmed by others. Also, after the sealed letter M is opened, since the antenna portion D1a returns to its original state, normal communication becomes possible and it can be used as the RFID tag D1.

[0052] That is, in the envelope paper P2 according to the first embodiment, after enclosing and sealing the contents, the communication sensitivity as the RFID tag D1 decreases and the communication distance becomes short, making it difficult to read data by a reading device (not shown), so security and privacy can be protected. Also, compared with methods such as wrapping the RFID tag D1 in a film bag having conductivity, it becomes possible to control the sensitivity of the RFID tag D1 at low cost.

[0053] It is desirable to set the mounting position of the RFID tag D1 such that the vicinity of the center of the entire length of the RFID tag D1 becomes the bending position.

[0054] Next, a second embodiment of the envelope paper P2 used in the encapsulation and sealing device 5 according to the present embodiment will be described. FIG. 8 is an explanatory diagram showing the envelope paper P2 according to the second embodiment, FIG. 9A is an explanatory diagram showing a folded state of the envelope paper P2, and FIG. 9B is a cross-sectional view when the envelope is sealed.

[0055] As shown in FIG. 8, the envelope paper P2 is composed of a single sheet of paper and includes a first constituent paper 201, a second constituent paper 202, and a flap portion 203. Between the flap portion 203 and the first constituent paper 201, there is a folding portion L11, and between the first constituent paper 201 and the second constituent paper 202, there is a folding portion L12.

[0056] A rectangular cutout region R2 is formed so as to straddle the first constituent paper 201 and the flap portion 203. The periphery of the cutout region R2 is a cut line L13, and the user can easily separate the cutout region R2 from the envelope paper P2 by the cut line L13.

[0057] Similar to the first embodiment described above, an admission ticket for entering a specific venue, for example, is formed in the cutout region R2. A rectangular RFID tag D2 is mounted in the cutout region R2 of the flap portion 203.

[0058] Aluminum vapor deposition sheets Q1, Q2 (shielding members) are mounted on the first constituent paper 201 and the second constituent paper 202, respectively. Each of the aluminum vapor deposition sheets Q1, Q2 is installed at a position that exactly overlaps the RFID tag D2 when the folding portions L11, L12 are folded. Specifically, by first folding the folding portion L11, when the flap portion 203 is overlapped with the first constituent paper 201, the RFID tag D2 is arranged to overlap with the aluminum vapor deposition sheet Q1. Next, by folding the folding portion L12, when the second constituent paper 202 is overlapped with the flap portion 203, the aluminum vapor deposition sheet Q2 is arranged to overlap with the RFID tag D2.

[0059] That is, by folding the envelope paper P2 shown in FIG. 8 into three folds, as shown in FIGS. 9A and 9B, the RFID tag D2 is sandwiched between two aluminum vapor deposition sheets Q1 and Q2, and in this state, the sealed letter M is formed. Therefore, in the state where the sealed letter M is sealed, since the RFID tag D2 is sandwiched between the two aluminum vapor deposition sheets Q1 and Q2, the sensitivity of the RFID tag D2 is reduced, making it difficult to perform skimming using a reading device or the like, and leakage of information can be avoided.

[0060] Also, when the user who has received the sealed letter M opens the sealed letter M and flattens the envelope paper P2, the RFID tag D2 is separated from the aluminum vapor deposition sheets Q1 and Q2, so normal communication becomes possible. Therefore, when the user who has received the sealed letter M opens it and further cuts off the cut line L13 described above to separate the admission ticket, communication using the RFID tag D2 provided on the admission ticket becomes possible.

[0061] That is, in the envelope paper P2 according to the second embodiment, after folding the envelope paper P2 into three folds and sealing the sealed letter M, the communication distance as the RFID tag D2 becomes short, and it becomes difficult to read data by a reading device, so security and privacy can be protected. Also, it becomes possible to control the sensitivity of the RFID tag D2 by an inexpensive method.

[0062] Also, instead of the aluminum vapor deposition sheet Q1 shown in FIG. 8, a security seal having adhesiveness is attached, and by adopting a configuration in which a part of the security seal remains on the RFID tag D2 after opening, the communication sensitivity of the RFID tag D2 can be improved.

[0063] Hereinafter, it will be described in detail with reference to FIGS. 10A to 10C. FIG. 10A is a view showing a state in which the security seal q1 covers the RFID tag D2, that is, a state in which the bent portion L11 shown in FIG. 8 is bent and the RFID tag D2 and the security seal q2 overlap. FIG. 10B is a view showing the state of the RFID tag D2 after opening, and FIG. 10C is a view showing the state of the security seal q1 after opening.

[0064] When the sealed letter M is opened with the security seal q1 attached to the RFID tag D2 as shown in FIG. 10A, the notch d separated from the security seal q1 is connected to the RFID tag D2 as shown in FIG. 10B. Also, the characters "opened" are transferred to the RFID tag D2 side. Further, as shown in FIG. 10C, the security seal q1 becomes the area d0 excluding the notch d.

[0065] As shown in FIG. 11, since the notches d remain at both ends of the RFID tag D2, the aluminum pattern of the notch d functions as a booster antenna, and the communication sensitivity of the RFID tag D2 can be improved. That is, as shown in FIG. 11, when the user opens the sealed letter M, the RFID tag D2 with the aluminum notch d attached in the cut-out area R2 is mounted, and when the cut-out area R2 is separated by the cut line L13 and used, the communication sensitivity of the RFID tag D2 can be improved.

[0066] It is also possible to attach the RFID tag D2 to the content paper P1 inserted into the sealed letter M. That is, as shown in FIG. 12A, the RFID tag D2 is attached to the back surface of the content paper P1, folded into three folds, and the content paper P1 is inserted into an envelope formed by the envelope paper P2. Also, the security seal q1 is attached to the flap portion 203. By folding the envelope paper P2 at the folding portion L11, the RFID tag D2 and the security seal q2 overlap. Therefore, the communication sensitivity of the RFID tag D2 can be reduced.

[0067] When the user opens the envelope and spreads out the content paper P1, characters are displayed on the front surface as shown in FIG. 12B, and the content paper P1 with the RFID tag D2 attached to the back surface can be taken out as shown in FIG. 12C. At this time, the notch d separated from the security seal q1 is connected to the RFID tag D2. Therefore, the communication sensitivity of the RFID tag D2 mounted on the admission ticket used after opening can be improved.

[0068] Furthermore, the present invention is not limited to the above-described embodiments as they are, and components can be modified and embodied without departing from the gist thereof at the implementation stage. Also, various inventions can be formed by appropriately combining a plurality of components disclosed in the above-described embodiments. For example, all the components shown in the embodiments may be appropriately combined. Of course, various modifications and applications are possible within the scope not departing from the gist of the invention. The invention described in the claims of the present application at the time of original filing is appended below.
