In addition, the first sealed portion 123 is sealed. Thereafter, pressure is applied to the pressure-sensitive adhesive pastes 59 and 61 by the second sealing portion 125, so that the sealed letter M is completely sealed.

FIG. 5B is a cross-sectional view taken along the line CC ′ shown in FIG. 5A in the sealed letter M completely sealed. The first fold portion 51 and the second fold portion 55 form the contents P sandwiched between envelope sheets PE by the respective constituent sheets 47, 49, 51, and the sealed letter M is formed.

The above is a form which discharges in the state which sealed envelope form PE through envelope form PE, the content P, the 1st sealing part 123, and the 2nd sealing part 125 completely.

However, when creating such a completely sealed direct mail, the contents can be set in the paper feeding unit 111 and only a limited sheet that is a recording medium that can be printed by the printing unit 114 is sealed. I can't. Therefore, there is a problem that it is impossible to enclose materials having various shapes, for example, sample articles, compact discs, and printed materials having special sizes and shapes.

Therefore, as illustrated in FIG. 2, the transport unit 130 is configured to be transportable along a path B that does not pass through the first sealing unit 123. The conveyance unit 130 is further guided by a conveyance guide plate rotation motor 137 that rotates and conveys the conveyance guide plate 133 in the direction of path B, and a conveyance guide plate 133 that is rotated by the conveyance guide plate rotation motor 137.

The abutting plate 135 is connected to the abutting plate moving motor 139 and a rack gear (not shown), and is configured to be movable downstream in the sheet conveying direction.

In the present embodiment, as the second path B, there is a path in which the envelope form PE in which the contents P are accommodated by the accommodating part 122 is not sealed by the first sealing part 123. In this route B, it is discharged in a state where it is not completely sealed as shown in FIG. Since water is not applied to the envelope foam PE, there is no state of being temporarily sealed by the re-wetting paste 63 on the envelope foam PE, and the contents P are simply folded via the second folding portion 55 by the accommodating portion 122. It is the state accommodated in the envelope form PE of the state. Thereafter, the envelope foam PE containing the contents P is conveyed to the branch roller 143.

Here, with reference to FIG. 6 and FIG. As shown in FIG. 6A, the envelope foam PE and the contents P are carried in a state in which the contents P are wrapped in the accommodating portion 122 located on the upstream side of the water application processing carry-in roller 131. At that time, the envelope foam PE and the contents P are transported through the transport guide plate 133 until they hit the butting plate 135. The sensor 147 is disposed in the vicinity of the end closest to the abutting plate 135 of the conveyance guide plate 133.

As shown in FIG. 7, when the envelope form PE containing the contents P is conveyed, the sensor 147 becomes an ON signal when detected. When the sensor 147 detects the presence of paper for a predetermined time T1, the water application processing carry-in roller 131 stops its rotation state.

Next, as shown in FIG. 6B, after the water application treatment carry-in roller 131 is stopped after a predetermined time T1, the conveyance guide plate 133 is rotationally driven, and the rotational driving is stopped after the predetermined time T2. To do.

Thereby, the envelope form PE in which the contents P are accommodated is raised by the abutting plate 135 for a predetermined time T3. As shown in FIG. 7, after raising the butting plate 135 for a predetermined time T3, the rotation of the branch roller 143 is started. As the butting plate 135 rises, the envelope foam PE containing the contents P rises, and is drawn into the rotating branch roller 143 and conveyed to the path B.

In the present embodiment, whether or not the route A or route B or route B is transported to the route BA or route BB, which will be described later, is used as sealing information when operating the sealing and sealing device 120. The user can set the print data for each envelope passage or for each series of jobs. Then, the route is selectively determined according to the user setting, and the envelope is discharged.

Here, there is a demand for various items to be included in the direct mail depending on the user. Depending on what is inserted into the direct mail, for example, in the case of a ticket or the like formed of cardboard, if the crimping in the direction along the envelope deployment direction ED parallel to the transport direction of the envelope form PE is performed, then the user's After inserting a ticket or the like into the envelope form PE by hand, the envelope short side direction SD perpendicular to the envelope developing direction ED can be sealed to completely seal it.

In this way, even when water is not applied to the re-wetting paste 63, if the envelope is pressure-bonded along the envelope deployment direction ED, the subsequent sealing operation in the envelope deployment direction ED by the user's hand is wasted. It can be omitted, and the portion that is not sealed can be changed according to the specific inclusion, which is highly convenient for the user.

Therefore, in this embodiment, as shown in FIG. 2, the branching roller 143 branches from the second path B by the branching portion 145, and further passes through the crimping portion 125 that is the second sealing portion. A first branch path BA and a second branch path BB that does not pass through the crimping part 125 that is the second sealing part are provided.

Switch control to. The crimping unit 125 performs the crimping in the direction along the sheet conveyance direction from the branching unit 145 via the second branch path BA, and is conveyed to the ascending conveyance belt 129.

In the present embodiment, the envelope foam PE and the contents P as shown in FIG. 4 are pressure-bonded in the envelope developing direction ED by the pressure-sensitive adhesive pastes 59 and 61, and the re-moistening paste 63 is sealed with the re-moistening paste by water application. It is discharged without being done.

In this embodiment, when sealing by water application is not performed and sealing by pressure bonding is not performed, the envelope foam PE passes through the second branch path BB. The branching unit 145 can control the switching of the transport path in the direction of the first branch path BA or the second branch path BB using a solenoid mechanism or the like (not shown) so that the transport is performed in the direction of the second branch path BB. Switch control to. Thereafter, the envelope foam PE containing the contents P is conveyed from the branching portion 145 to the ascending conveyance belt 129 via the second branch path BB.

In the present embodiment, the envelope form PE and the contents P as shown in FIG. 4 are discharged without being crimped by the pressure-bonding pastes 59 and 61 and sealed by the re-moistening paste by water application.

As described above, in the present embodiment, the path A for performing the first sealing in the envelope short-side direction SD by the re-wetting paste 63 and the second sealing in the envelope developing direction ED by the pressure-sensitive adhesive pastes 59 and 61, and the re-wetting The path BA in which the first sealing in the envelope short side direction SD by the glue 63 is not performed, and the second sealing in the envelope developing direction ED by the pressure-bonding glues 59 and 61, and the envelope short side direction SD by the rewet glue 63 are performed. And a path BB that does not perform the second sealing in the envelope developing direction ED by the pressure-sensitive adhesive pastes 59 and 61. As a result, an unsealed state corresponding to the insert in the direct mail can be realized.
