Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording apparatus capable of laminating a recorded member.

In recent years, the surface of recording paper that has finished recording is often laminated. In particular, in the case of color images, lamination increases the degree of vividness of the orange color and maintains the initial image quality even during long-term storage. Also, the water resistance of the recording paper depends on how it is laminated.

There are also advantages such as increased strength.

However, conventionally, such lamination processing on recording paper and the like has not been performed using a laminate coating device (hereinafter referred to as a laminator) provided separately from the recording device. Therefore, it is inconvenient that the recording paper that has been recorded in the recording apparatus must be carried one by one to the laminator to be laminated.

In view of these points, the present applicant has previously prepared 9% of the resin solution.
We have proposed an H self-recording device that is equipped with a printing function and can easily and quickly laminate recorded members with resin.

Here, in such a recording device, it is required that a uniform and defect-free coating film '81-m made of resin be formed on the recording member, and the resin film (laminate material) is required to be formed on the recording member. It is also necessary to improve the adhesion of the art material to prevent it from peeling off from the member.

In view of this, an object of the present invention is to apply a resin solution as a laminate material to the image forming surface of a recording member multiple times in layers, so that after image formation Q-, + By doing lamination processing on the surface,

Next, FIG. 3 shows a time chart of the operation of each part of the unfired ψ1 device shown in FIG.

The entire laminating operation of the apparatus shown in FIG. 1 will be briefly explained below with reference to FIG.

First, when the operation is stopped, self-recording paper 1 is normally
In the state shown in the figure, the tip 21 is located near the cutter 18. When the operation starts 1 time under such a state, the conveyance roller pair 3°4.1

Next, h is applied to the coating roller 14-2 in the same manner.
, (JI fat solution 12-2 is applied.

The recording paper 1, which has been laminated with an image forming +T+i VCWj fat bath solution, is transferred to rollers 15-1 and 15-1 via coating rollers 14-1 and 14-2.
5-2 and 16, and is conveyed toward the roller pair 17. Here, between the roller 14-2 and the roller pair 17, the 11? The entire coating is formed.

Next, at time T3, the cuckoo 18 drives,
t", the lent recording paper 1 is cut.

At this time, the head of the formed image 1iij on the recording paper 1 is controlled to be at the cutting position of the cuckoo 18. -force,
Recording operation on recording paper 1 by head 8 and 1. of recording trial 1. ;The λ feeding continues, and the leading edge of the cut recording paper l is held in the fl paper roller pair 19, and is conveyed to the paper discharge tray 20. The conveyance operation is performed by the head 8 at time T4. It continues even after the self-recording operation ends.

The conveyance operation is continued for a predetermined time (Ire 1i+), and after the formation teeth appear on the recording paper 1, y! When the cutter 18 reaches the cutting F1 position, the cutter 18 is moved (t) and the recording paper 1 is cut (FIG. 3, [1, y mark T5).

Thereafter, the driving of all the rollers other than the 4/1 paper roller phantom 19 is stopped, and the conveyance operation of the recording paper 1 is stopped. On the other hand, as described above, the recording paper 1 that has been laminated and cut at the front and rear edges of the formed image is discharged to the 411 paper tray 20 by the 4J:A4-ratio J19.

As described above, according to this embodiment, a resin solution was heavily applied as a laminating material to the image forming surface of the recording paper after recording was completed, and this (O1% liquid) was dried and solidified. By the way, since the recording is done by laminating, the recording paper can be completely covered with the laminate material. The adhesion of these art materials will not be impaired due to the entry of air bubbles, etc.Furthermore, according to this example, since a resin solution was used as the laminating material, it is possible to use a transparent resin film or the like as the laminating material. Unlike in the case where the recording paper and the laminate format were used, control such as size matching and positioning between the recording paper and the laminated paper becomes unreliable.

In addition, in this embodiment, the roller 14-1 and the workpiece 4-
2, the resin solution applied to the ml recording paper 1 was dried naturally at the internal temperature of the machine, but instead of this, for example, the roller 14-1, the guide roller 15-1, the guide rollers 15-2 and 167, etc. A blower may be provided as a drying means between the two, and in such a case, the drying time of the j'jjJi# solution is shortened, and the recording paper transport distance from the roller 14-2 to the transport roller pair 17 is completely shortened. I can do j-things.

Ma/ko, as an example of this skill...r;l:, Is it possible to recoat the 11 solution every month with the 21 hard rollers 14-1 and O-14-2? It is also possible to add an additional layer of j'+l and apply the #"rJ IIJ solution three times or more.

As explained above, according to the invention, a resin solution is applied as a laminating phase onto the image forming surface of a recording member, and then the recording member is laminated after image formation. Since it is natural, the percentage of siminate material = complete coverage of the e-recording material, and '? Improved EXi performance can be achieved.

Further, according to the present invention, there is no need for adjusting the size of the recording paper and the simulating material, which is required when transparent resin laminate is used as the simulating phase, thereby simplifying the lamination process. I can do it.

In this embodiment, we have described the case where the material to be recorded is t51≦a roll material, but it goes without saying that this also applies to a sheet material.

In addition, we have performed single-sided N1 recording on the wave recording surface and have only described the single-sided lamination force 11 on the recorded surface.
By applying the present invention, it is also possible to perform double-sided recording and laminate both sides.

Furthermore, in this example, an inkjet head was used as a recording means. Although an inkjet head is advantageous in reducing the size of the apparatus, the present invention is not particularly limited thereto, and thermal recording such as a thermal transfer method, electrostatic recording, etc. can also be used.
