Description

  The present invention relates to an image recording apparatus capable of performing both the production of a bag, the production of a pressure-bonded printed material, and the production of a color printed material.

Conventionally, in order to transmit character information only to a specific individual, generally, the character description is in a sealed form so that the individual can confirm the character information only after opening.
In recent years, personal information protection has become a strict question, and various business establishments, for example, personal information such as various personal data, gradebooks, salary statements, etc., are printed on the printed part of the written text. It is recorded and distributed in the form of envelopes or cards by bonding or crimping the peripheral edge of the printed part or the entire surface of the written text.

  Among these, postcard-sized cards are called crimped postcards and can be used at the same charge as regular postcards. Therefore, as a printing information concealment system that is highly convenient for information providers, advertising It is also widely used for advertising direct mail.

  In order to use such a printing information concealment system for crimping postcards, etc., secret information has conventionally been created by entrusting it to a specialized manufacturer or introducing an expensive crimping postcard or other manufacturing / printing device. .

  There are two methods for creating confidential information using a manufacturing / printing device such as a crimping postcard, such as a method of applying adhesive after information printing or a method of applying adhesive before information printing. The premise of creating a large amount of information is essential and expensive.

Further, such outsourcing to a manufacturer is not a preferable method for creating confidential information because there is a potential problem of leakage of personal information.
By the way, in recent years, along with the development of personal computers and printers, there has been proposed one that can easily create a crimp postcard even in a small unit so that it can be used by small-scale offices and individuals.

  For example, postcard paper with release paper pre-applied with a pressure sensitive adhesive is on the market. In this method, after printing predetermined character information or the like on the printing surface inside the two-fold, the pressure-sensitive adhesive portion is crimped to complete a postcard for postage.

  For example, a set of adhesive film and postcard paper is sold. In this method, after printing predetermined character information or the like on the printing surface inside the double fold, the adhesive film is pressure-bonded with the adhesive film sandwiched inside, so that a postcard for posting can be created.

  However, this is inevitable, and the handling is cumbersome, and it is better to personally create several crimped postcards, but it is cheap, quick, and responsive to demand in a certain number of units. It can not be created with.

  Therefore, a toner-like adhesive composed of microcapsules containing an adhesive is transferred onto the surface of the substrate by electrostatic printing and flash-fixed. At the time of adhesion, the microcapsules are destroyed by pressure and the adhesive in the capsule is leached. In this way, a proposal has been made that it is possible to easily create a pressure-bonded postcard. This proposal also suggests a pulverized toner obtained by melting, kneading, and pulverizing an adhesive. (For example, refer to Patent Document 1.)

  In addition, the pressure bonding substance is put into a replacement printing cartridge for an office printer or a copying machine, and the pressure bonding substance is applied to a government postcard or envelope by the same operation as the printing operation by the office printer or copying machine. After that, a proposal has been made that it can be applied to a dedicated crimping machine, and a single printer or copying machine can be used to reach the dedicated crimping machine. In addition, this proposal suggests that a crimping substance is applied to one side of a fold and one side of a center of a fold. (For example, see Patent Document 2.)

  In addition, a method has been proposed in which a toner containing a heat-sensitive adhesive is used, and an image is created in a demand-responsive manner by an electrophotographic method. In this proposal, the softening temperature of the heat-sensitive adhesive is configured to be higher than the softening temperature of the binder resin of the toner for electrophotography, and the ratio of the heat-sensitive adhesive to the toner for electrophotography is 5 to 5. It has been proposed that the composition be 60% by weight and that the composition of the heat-sensitive adhesive contains at least one selected from the group consisting of a heat-adhesive resin, a hot melt, and waxes. (For example, see Patent Document 3.)

Conventionally, when manufacturing various types of paper bags and various types of film bags, a special large-sized apparatus is used to manufacture a large number of bags from a roll-shaped original fabric. (For example, see Patent Document 4)
The user generally purchases and uses various bags manufactured by such an apparatus for various purposes.

In addition, a method has been proposed in which toner is used as an adhesive for adhering the three-side periphery of the sheet when the upper sheet and the lower sheet are overlapped to form a bag. (For example, refer to Patent Document 5.)
JP 09-104849 A (paragraphs 0005, 0014, FIG. 1, FIG. 3, FIG. 6) JP 2000-006553 A (summary, no figure) Japanese Patent Laying-Open No. 2004-126231 (paragraphs 0085 to 0087, not shown) JP 2000-203593 A (summary) JP 2003-040278 (Abstract, FIGS. 1 and 3)

  However, although the technology of Patent Document 1 describes the configuration and composition of the microcapsule toner, the pulverized toner is merely suggested to the extent that it is conceived, and the specific composition, production method, There is no description about the usage, and this makes it possible for even those skilled in the art to produce useful pulverized toners and, of course, not even make prototypes.

  In addition, the technology of Patent Document 2 is to create a print information concealment document by a public postcard or envelope before being applied to a dedicated crimping machine, and it is convenient in that it must be applied to the dedicated crimping machine to complete for posting. It must be said that it is lacking in performance and economy and is far from being responsive to demand.

  Further, in the technique of Patent Document 3, the softening temperature of the heat-sensitive adhesive is merely set higher than the softening temperature of the binder resin of the toner for the electrophotographic method, but it is suggested to the extent of the idea. No specific material formulation or specific usage of toner containing heat sensitive adhesive is disclosed.

  Also, such a toner adhesive powder adhesive for postcards has not been distributed to the market to date. The adhesives for pressure-bonding postcards in circulation are only liquid or pressure-sensitive adhesive sheets.

  In addition, Patent Documents 4 and 5 described above merely show a method for creating a bag, and no device is used to create the bag.

  Aside from that, bags are generally purchased items, so when using, you must place an order for each type of bag (purpose of use) and size (shape) of the bag. .

  And it is necessary to store and manage inventory for each type and size. Further, in actual use, as described above, there is a problem in that it requires a complicated work for manually writing individual information or performing printing. In addition, there is a problem that it is expensive because it is a purchased item.

  In view of the above-mentioned conventional situation, the object of the present invention is to establish a practical method for producing a powder adhesive, and then to produce a bag and a pressure-bonded printed material by electrophotography using the powder adhesive.

(Embodiment 2)
<Image recording device>
Subsequently, an image recording apparatus for producing a bag or a pressure-bonded printed material using the powder adhesive produced as described above will be described.

  FIG. 1 is a block diagram illustrating a configuration of an image recording apparatus according to the second embodiment. In FIG. 1, an image recording apparatus 1 includes, from the right to the left in the figure, a paper feeding device 2, a printing and adhesive application device 3, a bag / crimp printed material completion device 4, and a finished sheet storage device 5.

  The sheet feeding device 2 accommodates a large number of sheets 6 that have been cut into sheet-like predetermined dimensions in advance. This sheet 6 is a paper-like or film-like member capable of printing or printing on the surface, for example.

  The printing and adhesive application device 3 includes a printing unit 7, a resin powder application unit 8, a sheet conveying unit 9, a sheet surface reversing device 11, and a fixing unit 12.

  The printing unit 7 includes three electrophotographic toner image forming units (hereinafter simply referred to as image forming units) 13 (13m, 13c, 13y), and includes a conveying belt 14 and a transfer roller of the sheet conveying unit 9. 15, a color image is formed on the sheet 6 conveyed by the conveying belt 14 as necessary.

  That is, the image forming unit 13m forms a magenta color image using magenta toner. The image forming unit 13c forms a cyan toner image using cyan toner. The image forming unit 13y forms a yellow toner image using yellow toner. Then, these three color separation images are overlaid, and a full color variable information image is formed on the printing surface of the sheet 6.

  The image forming unit 13 of the printing unit 7 is not limited to magenta, cyan, and yellow three-color printing, and the number may be increased or decreased depending on the type of printing color required. That is, only one image forming unit 13 is required for monochrome printing.

  When it is necessary to print with finer gradations, a total of six image forming units 13 are arranged by adding two intermediate gradation colors such as light magenta and ride cyan. It can also be done. The printing unit 7 may be an inkjet image forming unit instead of the electrophotographic image forming unit 13 using toner.

  Next, in the configuration of this example, the powder adhesive application unit 8 includes a powder adhesive application device 16 having the same configuration as the electrophotographic toner image forming unit 13 described above. In the powder adhesive application device 16, a powder adhesive having an adhesive function is used instead of toner.

  The image forming unit 13 and the powder adhesive coating device 16 have the same configuration except for the powder to be used. Therefore, the configuration will be briefly described by taking the image forming unit 13y as a representative.

  The image forming unit 13y includes at least a powder hopper 17, a developing unit 18 provided below the developing unit 18, a developing roller 19 rotatably disposed in a lower end opening of the developing unit 18, and the developing roller. 19 and a photosensitive drum 21 arranged in contact with the conveying belt 14 of the sheet conveying section 9 and a recording head 22 arranged close to the upper peripheral surface of the photosensitive drum 21.

  The powder hopper 17 opens a lower supply port (not shown) when the amount of toner (or powder adhesive, the same applies hereinafter) contained in the lower developing device 18 becomes a predetermined amount or less, and supplies the toner to the developing device 18. refill.

  The developing roller 19 rotates while holding the toner in the developing unit 18 in a thin layer state on the peripheral surface thereof. The photosensitive drum 21 is charged with, for example, a high minus potential by applying a predetermined charge to the peripheral surface potential by an initialization charger (not shown).

  The recording head 22 exposes the peripheral surface of the photosensitive drum 21 charged to a high minus potential based on image forming information transmitted from a host device (not shown) to attenuate the potential. As a result, an electrostatic latent image is formed on the peripheral surface of the photoconductor drum 21 with a high negative potential of initialization charge and a low negative potential attenuated by exposure.

  The photosensitive drum 21 rotates in the clockwise direction in the figure, and toner is transferred from the developing roller 19 to a low minus potential portion at a portion facing the developing roller 19. As a result, the toner image or the powder adhesive image is developed on the low negative potential portion on the peripheral surface of the photosensitive drum 21 (in the case of reversal development).

  The sheet conveying unit 9 includes a driving roller 23 and a driven roller 24 that rotate the conveying belt 14 described above. The conveying belt 14 is stretched between the driving roller 23 and the driven roller 24, and is driven by the driving roller 23 to circulate in the counterclockwise direction in the drawing.

  The toner image or the powder adhesive image is transferred to the sheet 6 conveyed as indicated by the arrow a by the conveying belt 14 of the sheet conveying unit 9 at the opposite part between the photosensitive drum 21 and the transfer roller 15. The

  While the sheet 6 is being conveyed by the conveying belt 14 as indicated by an arrow b, a magenta toner image is formed from the photosensitive drum 21 of the image forming unit 13m, a cyan toner image is formed from the photosensitive drum 21 of the image forming unit 13c, and image formation is performed. A yellow toner image is sequentially transferred in a superimposed manner from the photosensitive drum 21 of the unit 13y. At this time, the driving of the powder adhesive applicator 16 is stopped.

  The sheet 6 on which the three color separation toner images are transferred (overcoated) and the full color toner image is formed on the printing surface passes through the fixing unit 12. As a result, the full-color toner image transferred to the sheet 6 is fixed to the sheet 6.

  Following the above, the sheet 6 is carried into the bag / press-bonded printed product completion device 4. The bag / crimp printed material completion device 4 is provided with a sheet folding part 25, a crimping part 26, a separation part 27, and a discharge part 28.

<Sheet folding device>
Next, a method for folding a sheet material (sheet-like bag material or sheet-like pressure-bonded printed material) into two or three folds using the sheet folding unit 25 of the image recording apparatus 1 having the above configuration will be described.

FIGS. 2A to 2E are diagrams showing a folding method of the sheet 6 that is carried into the completion device 4 and folded in half at the sheet folding section 25. FIG.
In addition, the folding device of the sheet folding part 25 shown to the same figure (a)-(e) can perform not only the folding operation for a bag or two-fold crimping printed matter but also the three-folding operation for three-fold crimping printed matter. . Moreover, in the following description, the sheet-like bag material or the press-printed printed material to be folded in half is collectively referred to as “sheet P2”.

  First, as shown by the arrow k in FIG. 2A, the sheet P2 is carried into the folding entrance 31 of the sheet folding section 25. Therefore, the primary conveyance roller 32 and the primary secondary conveyance roller 33 are paired to grip and rotate the sheet P2, and operate to send the sheet P2 to the primary drawing path 34 as shown in FIG. 2 (b). To do.

  As shown in FIG. 2 (b), the primary folding device 35 projects the fold of the sheet P2 stretched between the folding carry-in entrance 31 and the primary drawing-in path 34 and projects the folding plate 36 as shown in FIG. 2 (c). Then, it is folded into the opposite portion between the primary / secondary transport roller 33 and the secondary / third transport roller 37.

  Subsequently, as shown in FIG. 2 (d), the primary / secondary conveyance roller 33 and the secondary / tertiary conveyance roller 37 are paired to grip and rotate the folded leading end of the sheet P2, thereby rotating the sheet P2 to the second position. It operates to feed in the direction of the next drawing-in path 38.

  The secondary folding device 41 projects the folding and guiding plate 42 at a timing when the folded front end of the sheet P2 slightly passes the facing portion between the secondary tertiary transport roller 37 and the tertiary transport roller 39, and the sheet P2 Is guided in the direction of the opposing portion between the secondary and tertiary conveyance rollers 37 and the tertiary conveyance roller 39.

  The secondary and tertiary conveyance rollers 37 and the tertiary conveyance roller 39 sandwich and rotate the leading end of the sheet P2 that is folded and protruded. As a result, as shown in FIG. 2 (e), the sheet P2 is sent out to the carry-in port 43 of the crimping device 26 while the succeeding portion is folded in two from the folding leading end portion.

Subsequently, the folding of the sheet-like pressure-bonded printed material in three folds will be described.
FIGS. 3A to 3E are diagrams showing a folding method of the sheet 6 that is carried into the completion apparatus 4 and is folded in three at the sheet folding unit 25. FIG. In addition, the sheet-like pressure-bonded printed material to be folded in three is referred to as “sheet P3” in the following description.

  First, FIG. 3 (a) shows a state where the sheet has been folded in the same manner as in FIGS. 2 (a) to 2 (d). Thereafter, the primary conveyance roller 32 and the primary secondary conveyance roller 33 are paired to send out the rear portion of the sheet P3, and the primary secondary conveyance roller 33 and the secondary tertiary conveyance roller 37 are paired to form the above-described sheet P3. As shown in FIG. 3B, the sheet P3 is fed in the direction of the secondary pull-in path 38 by gripping and rotating the half-folded portion.

  At the timing when the mating portion P3-12 of the first sheet P3-1 and the second sheet P3-2 folded in the two of the sheet P3 comes to the opposing portion of the secondary and tertiary conveyance roller 37 and the tertiary conveyance roller 39. As shown in FIG. 3C, the secondary folding device 41 projects the folding / guide plate 42 and folds the third sheet P3-3 at the rearmost portion of the sheet P3.

  The secondary and tertiary conveyance rollers 37 and the tertiary conveyance roller 39 are paired, and the third sheet P3-3 at the end of the sheet P3 is folded as shown in FIG. Rotates with the folded part sandwiched.

  As a result, as shown in FIG. 3 (e), the sheet P 3 is sent out to the carry-in port 43 of the pressure bonding device 26 while being folded in three by the secondary and tertiary transport rollers 37 and the tertiary transport rollers 39.

  Returning to FIG. 1, as shown in FIG. 2 or FIG. 3, the bi-folded sheet P <b> 2 or the tri-folded sheet P <b> 3 fed to the carry-in port 43 of the crimping device 26 is immediately carried into the main body of the crimping device 26. Then, preheating, heating and pressure are applied and crimped.

<Crimping device>
Here, the heat conduction to the pressure bonding surface of the sheet P2 or the sheet P3 in the case where the pressure bonding device 26 includes only a pair of heat rollers will be considered.

  FIG. 4 (a) shows the manner of crimping in the case of the bi-folded sheet P2 when the crimping device 26 is composed of only a pair of heat rollers, and FIG. 4 (b) shows the tri-folding in the same case. It is a figure which shows the aspect of the crimping | compression-bonding in the case of the sheet | seat P3.

  In any of the cases shown in FIGS. 4A and 4B, the adhesive 44 is sandwiched between the press-bonded printed sheets P2 or P3. In order to heat and melt the adhesive 44, it is necessary to sandwich and press it from the outside with a pair of heat rollers 45 (45a, 45b) and to transmit heat through the pressure-bonded printed sheet P2 or P3 as indicated by arrows m and n. There is.

  As described above, heat cannot be directly transferred from the heat roller to the adhesive 44 as in the printer fixing device. Therefore, in order to melt the adhesive 44, the heat roller 45 is necessary for the printer fixing device. Heat that is many times higher than the required heat is required.

  However, in the method of this example in which the adhesive 44 is powdered and applied to the pressure-bonded printed matter using electrostatic development, the storage stability of the toner (adhesive) is maintained and the mechanical property of the stirring device in the developing device is maintained. In order to obtain resistance to a load, there is a limit to lowering the softening point of the toner (adhesive).

  Even if the softening point of the adhesive can be lowered by ignoring the surrounding conditions, in the crimping configuration using the printer fixing unit, it is necessary to carry out crimping while conveying the crimped printed paper at a high linear velocity. It is impossible and causes a decrease in efficiency. The crimping device 26 of this example shown in FIG. 1 solves the above problem.

  FIG. 5 (a) is an enlarged view showing only the crimping device 26, and FIG. 1 also shows a transport system in the vicinity of the main body device which is not shown in FIG. FIG. 2B is a perspective view showing the internal structure by taking out only the preheating unit of the crimping device 26.

  As shown in FIG. 5 (a), the crimping device 26 includes a conveyance roller pair 46 at the carry-in entrance 43, and a preheating unit 48 inside the main body device immediately before the upstream side of the heat roller pair 47 (47a, 47b). Is installed.

  The heat roller pair 47 has the same configuration as a general printer fixing device. That is, while being heated to a certain temperature, the heat rollers 47a and 47b are pressed against each other with a specified pressure. Moreover, it rotates by being driven from the drive system of the main unit.

  The other preheating unit 48, as shown in FIG. 5B, is a combination of a sheet metal 52 with two sets of assembly members 53 formed by sequentially laminating a heat insulating material 49, a heating element 51 and a sheet metal 52 with a predetermined gap therebetween. Are placed with their outer surfaces facing each other.

In other words, the stacking order of the sheet metal 52, the heating element 51, and the heat insulating material 49 is reversed above and below the two sets of assembly members 53.
In order to avoid adverse effects such as rubbing on the address printing of the pressure-bonded printed matter passing through the gap, the surface of the sheet metal 52 that faces the gap is separated from, for example, Teflon (registered trademark). Each surface treatment has good moldability.

Further, the predetermined gap needs to be in a range of 1 mm or less in order for the sheet P2 or P3 to be effectively heated. This is the result of various experiments.
Further, although not particularly shown, a temperature sensor is provided in proximity to the sheet metal 52. The heating temperature is controlled so that the heating element is driven on / off from the engine unit of the control unit by the temperature information detected by the temperature sensor, and the surface temperature of the sheet metal 52 becomes constant.

  This control temperature is controlled such that Ct = Mt−10 ° C., where Ct is the heating temperature of the heat roller pair 47 and the preheating unit 48 and Mt is the outflow start temperature of the adhesive 44. The outflow start temperature is a value measured with a flow tester manufactured by Shimadzu Corporation.

  As shown in FIG. 5A, when the length of the preheating unit 48 in the sheet conveyance direction indicated by the arrow m is L millimeters, the crimping device 26 sets the conveyance linear velocity of the sheet P2 or P3 to a millimeter / The second is configured to have a relationship of L / a = 0.2 or more.

  In addition, if the preheating unit 48 and the heat roller pair 47 are separated as much as possible, the gap between the preheating unit 48 becomes a non-heating section and the sheet heated by the preheating unit 48 is cooled.

  Therefore, in order to avoid this inconvenience, as shown in FIG. 5A, there is almost no gap between the paper discharge port 48-1 of the preheating unit 48 and the paper advance port 47-1 of the heat roll pair 47. It is arranged as close as possible to.

  The sheet P (P2 or P3) is printed in variable information by the printing unit 7 shown in FIG. 1, a powder adhesive application process by the powder adhesive application unit 8, and a two-fold or three-fold by the sheet folding unit 25.

<Size of pressure-bond printed sheet>
First, the size of the sheet for pressure-bonded printed matter will be described.

  FIGS. 8A and 8B are diagrams showing the sizes of the sheet-like sheets used for the pressure-bonded printed matter in the image recording apparatus 1, respectively.

  FIG. 5A shows an A4 sheet P2, which is folded in two along a fold line 66 and cut along a cutting line 67. Each side is 2 in which the length is 14.85 cm and the width is 10.5 cm. A two-fold press-bonded printed material can be produced.

  FIG. 2B shows a sheet P3 in which one end P ′ in the longitudinal direction of the A3 sheet is cut off by 10.5 cm in advance, and is divided into three along two folding lines 68. When the sheet is cut along the folding and cutting lines 69, two tri-fold press-bonded printed materials each having a length of 14.85 cm and a width of 10.5 cm can be produced.

  By the way, crimped postcards are usually handled as postcards, but according to the postal code, the size of one side of a private postcard is 14 to 15.4 cm on the long side and 9 to 10.7 cm on the short side. ing.

Therefore, the vertical and horizontal dimensions of one surface of the press-bonded printed material shown in FIGS. 8A and 8B are all within the allowable range of the postcards approved by the Postal Service.
The sheets P2 and P3 shown in FIGS. 8 (a) and 8 (b) are folded when variable information is printed on both sides, when a powder adhesive is applied, and when a powder adhesive is presupposed. When crimped, both are conveyed in the direction of the cutting line 67 or 69 indicated by the arrow b.

<Preparation of crimped printed material>
FIG. 9 (a) is a diagram showing a mode at the end of variable information printing on a folded sheet for crimped printed material, and FIG. 9 (b) is a diagram showing a mode at the end of powder adhesive application. c) is a diagram showing a state at the time of bending. With reference to FIGS. 9A, 9B, 9C and FIG. 1 again, the operation for producing a folded folded printed material will be described.

  First, the main unit shown in FIG. 1 is turned on, and when the sheet quality of the sheet P2 to be used, the number of sheets, the print mode, and other specifications are input as a key input or a signal from a connected host device, variable information is printed ( Printing) and subsequent application of the powder adhesive.

  First, the drive roller 23 rotates counterclockwise, and the driven roller 24 follows and similarly rotates counterclockwise. As a result, the conveying belt 14 is circulated and moved counterclockwise as a whole with the upper circulating portion coming into contact with the three photosensitive drums 21 of the printing unit 7.

  At the same time, the devices arranged around the photosensitive drum 21 are sequentially driven in accordance with the printing timing. The photosensitive drum 21 rotates in the clockwise direction, an initialization charger (not shown) applies a uniform high negative charge to the circumferential surface of the photosensitive drum 21, and the recording head 22 is placed on the circumferential surface of the photosensitive drum 21. Exposure is performed according to the image signal to form a low potential portion.

  As a result, an electrostatic latent image is formed on the circumferential surface of the photosensitive drum 21 from the high negative potential portion by the initialization and the low negative potential portion by the exposure. The developing roller 19 transfers the toner of the developing unit 18 to the low potential portion of the electrostatic latent image to form a toner image on the circumferential surface of the photosensitive drum 21 (reverse development).

  At the timing when the leading edge of the toner image on the circumferential surface of the photosensitive drum 21 of the most upstream toner image forming unit 13y is rotated and conveyed to a portion facing the conveying belt 14, the printing start position of the sheet P2 coincides with the opposite portion. As shown, an uppermost sheet 6 (sheet P2) placed and accommodated in the sheet feeding device 2 is taken out, and the first surface faces upward, as shown by an arrow a. 9 is fed.

  The conveying belt 14 conveys the fed sheet P2, and thereby the sheet P2 is conveyed to the first transfer portion formed by the photosensitive drum 21 and the transfer roller 15 of the toner image forming unit 13y.

  The transfer roller 15 applies a transfer current (or transfer voltage) output from a transfer bias power source (not shown) to the sheet P <b> 2 via the conveyance belt 14. As a result, the yellow (y) toner image is transferred onto the photosensitive drum 21 onto the sheet P2.

  Subsequently, a cyan (c) toner image is transferred at the second transfer portion from the upstream formed by the photosensitive drum 21 and the transfer roller 15 of the toner image forming unit 13c, and further the photosensitive member of the toner image forming unit 13m. A magenta (m) toner image is transferred at the third transfer portion from the upstream formed by the drum 21 and the transfer roller 15.

  In the first full color printing, the powder adhesive applicator 16 is set to a non-printing state. Accordingly, the sheet P2 onto which the three color toner images are transferred is conveyed by the conveying belt 14 as it is, separated from the conveying belt 14, and carried into the fixing unit 12.

  The fixing unit 12 presses and holds the sheet P2 between the heat generation roller and the pressing roller, and while conveying the sheet P2 in the downstream direction, applies heat and pressure to the sheet P2 to fix the toner image on the paper surface, and discharges it to the downstream side.

  At this time, the sheet P2 is in a state in which the sheet P2 shown in FIG. 9 (c) is opened, and address information which is public information is printed on the surface A. In FIG. 9 (c), the sheet P2 is hidden and cannot be seen. On the surface B, sender information, which is also public information, is printed. In addition to the sender information, notification information or advertisement information may be added as public information and printed.

  In this state, for example, in the case of single-sided printing during normal printing, the sheet P2 discharged from the fixing unit 12 is taken over by the bag / crimp printed material completion device 4 and passes through the completion device 4 to complete the completed sheet. It is stored in the storage device 5.

  However, as in this example, when a pressure-bonded printed material is produced, it is always double-sided printing. Therefore, as in the case of double-sided printing during normal printing, the sheet P2 is as shown by arrows c and d in FIG. It is carried into the sheet surface reversing device 11.

  The sheet P2 carried into the sheet surface reversing device 11 is sent back toward the sheet supply unit as indicated by arrows e, f, g, and h with the trailing end at the time of carrying in as the leading end. Then, the feeding direction is reversed from right to left, the second surface is directed upward, and the sheet is conveyed again by the conveying belt 14. At this time, in the sheet P2, the surface C and the surface D of the sheet P2 shown in FIG.

  Then, the powder adhesive application device 16 is set to a printing state.

That is, the transparent powder adhesive 44 is transferred over the confidential information 71 printed by the printing unit 7.

  The sheet P2 on which the secret information 71 made up of three-color toner images and the powder adhesive 44 are transferred in an overlapping manner is separated from the conveying belt 14 and carried into the fixing unit 12. The fixing unit 12 presses and holds the sheet P2 between the heat generation roller and the pressure roller, applies heat and pressure to the sheet P2 while conveying in the downstream direction, and fixes the toner image on the paper surface, and assumes the powder adhesive 44. The sheet P2 is discharged rearward.

  The sheet P2 discharged from the fixing unit 12 is taken over by the bag / compressed printed matter completion apparatus 4 and is folded in two at the sheet folding unit 25 as described with reference to FIG. FIG. 9 (c) shows the state of the sheet P2 at this time.

  Thereafter, the powder adhesive 44 presupposed on the surface C and the surface D is finally fixed by the pressure-bonding portion 26, and the surface C and the surface D are pressure-bonded. Then, the sheet is cut along the cutting line 67 by the separation unit 27, separated into two bi-fold press-bonded printed products, discharged to the outside by the discharge unit 28, and stored in the completed sheet storage device 5.

The variable information is fixed by the fixing unit 12 and the powder adhesive 44 is presupposed.

  Subsequently, the sheet P3 is carried into the sheet surface reversing device 11, is sent back toward the sheet supply unit as indicated by arrows e, f, g, and h, and is conveyed by the conveying belt 14 in a state where the front and back sides are reversed.

  Then, on the sheet P3, variable information as sender information is printed on the surface PD shown in FIG. 5C again by the printing unit 7, and variable information as confidential information is printed on the surfaces PE and PF. The surface PD may be printed with notification information or advertisement information in addition to the sender information.

  Subsequently, the powder adhesive 44 is applied to the confidential information printing surfaces PE and PF by the powder adhesive application unit 8 as shown in FIG. The variable information is fixed by the fixing unit 12 and the powder adhesive 44 is presupposed.

  The sheet P3 on which the variable information consisting of toner images of three colors is fixed on both the front and back sides and the powder adhesive 44 is presumably attached is taken over by the bag / crimp printed product completion device 4, and the sheet folding unit 25 Folded in half as described in 3. FIG. 10D shows the state of the sheet P3 at this time.

  Thereafter, the powder adhesive 44 presupposed on the surfaces PA and PB and the surfaces PE and PF is permanently fixed by the crimping portion 26 and crimped in a tri-fold shape. Then, the sheet is cut along the cutting line 69 by the separating unit 27, separated into two tri-fold crimped printed products, discharged to the outside by the discharging unit 28, and stored in the completed sheet storage device 5.
