For the transparent part of such recording medium, carry out image with above-mentioned method and form (Fig. 3 A-Fig. 3 E) and photographic fixing.Carried out the mirror image rotating image at transparent part and printed (mirror image printing) this moment.After the photographic fixing, carry out conveyance to the after-treatment device shown in Fig. 3 A-Fig. 3 E (final fixing device: make image form medium and make its combination, thereby form the device of recording medium) with photo style by the represented such doubling of Fig. 3 C.In addition, according to circumstances, in the image processing system of present embodiment, have difference pawl 6 after the photographic fixing,, just can perhaps arrange between the paper and switch arranging paper to row's paper 8 to after-treatment device (C direction) by it is switched.In after-treatment device, as the explanation of carrying out at reference Fig. 3 A-Fig. 3 E, after the direction of arrow of the front end that makes paper in Fig. 3 A is advanced, on the opportunity of regulation, the gyratory directions of roller 121 is switched, make the direction conveyance of principal direction roller 122, carry out doubling with toilet tissue.Then, pressurize, export after making the paper doubling with roller.
Among above-mentioned Fig. 2 A, be with the example of recording medium as 1 piece sheet material use.This recording medium is translucent half nontransparent form.This recording medium also can be such with Fig. 2 B, and a part is transparent form, and nontransparent part needs only opaque, is not limited to white.
The temperature-sensitive adhesive layer of Shi Yonging is when the image fixing of toner etc. in the present embodiment, because fixing time and photographic fixing pressure are little, so even fixing temperature surpasses the softening temperature or the fusing point of the thermoplastic resin that the temperature-sensitive cementing agent contained, because its fixing time is short, its effect as cementing agent also might be able to not be given full play to, so the possibility of adjustment is arranged in this image processing system.In toner image, during toner image, the face of toner image is when the temperature of fixing roller applies face and contacts, the preferential contact of the part of toner and fusion.At this moment, the fusion photographic fixing of toner is considered to mainly carry out at this.If the part of the toner image that contacts with adhering agent layer firmly combines with the temperature-sensitive adhesive layer, just can obtain the image that mirror image has rotated.In addition, thereby obtain in the recording medium of photo style in the doubling of carrying out like that of image shown in Fig. 3 A-Fig. 3 E of so having carried out the mirror image rotation, temperature-sensitive tack coat fusion and fusion does not take place toner, so the toner of photographic fixing can not be moved because of heating, in addition, adhesive layer with heat apply in pressurize, thereby toner image is by photographic fixing.
As above, according to present embodiment, on a sheet material, but have at least a portion is recording section and cohesiveness part, at described sheet material transparent part and non-transparent part are arranged, by described sheet material is folding, but can see from described transparent part at least a portion that described recording section is represented.And by the image recording medium that can bond, can be by image processing system, at least a portion be transparent recording medium and at least one mask the thermal sensitivity adhesive layer is arranged medium on form image, make them integrated then.The image of the photo style that can obtain having good keeping qualities thus.The image keeping quality and the conveyance that obtain like this are good, and have that the position adjustment of the sheet material of transparent part and recording medium becomes easily.According to the present invention, just can provide such recording medium and the image processing system that can form such recording medium thus.
In addition, by having the recording medium that at least a portion is a hyalomere, the hyalomere of the face that the image at least of hyalomere forms becomes film like to cover on the recording medium, the recording medium that compares favourably with picture quality photo the gloss with photo that obtains image smoothing thus and combine closely.
Moreover, be on the recording medium of hyalomere at least a portion, about original image is carried out or reverse up and down and the image of the recording medium that forms in the time of will watching after the output, just can be seen the normal picture that does not reverse.
In addition, recording medium and the sheet material that transparent part is arranged are constituted the occasion of a sheet material side by side, bond with recording medium portion owing to described sheet material can be turned up, so image processing system can save the paper supply conveyer.
In addition, owing to the temperature-sensitive adhesive layer at least by must the composition thermoplastic resin and solid plasticizer and add bonding as required and invest agent and form, it does not show viscosity at normal temperatures fully, but when heating, show cohesiveness, so temperature-sensitive adhesive layer of the present invention can keep cohesiveness after bonding semipermanently.
When the image formation of carrying out with toner on recording medium, because the fusing point of thermoplastic resin and solid plasticizer is lower than the fusing point of toner, even so heating when cohesiveness is occurred, also can be carried out image fixing and recording medium is bonded as one and do not make the toner image multilated.So, the cost of image processing system is raise and obtain the record images medium of photographic quality.
Embodiment 2
Below will image processing method and the image processing system as second embodiment of the present invention be described, the promptly independent respectively transparent and nontransparent sheet material of preparing, and after forming image on the transparent image, with clear sheet and nontransparent sheet material conveyance to bonding position and they are pasted together, thereby form the picture of photo formula image.
Fig. 8 is the sectional view of simple structure of describing the image processing system of present embodiment.In the image processing system of present embodiment, transfer printing unit is made of primary transfer unit and secondary transfer printing unit, also has the after-treatment device as attachment device simultaneously.In the configuration of each unit and each device, different with the image processing system of Fig. 1 of embodiment 1, still, the running that each member and image form is identical, so omit its explanation at this.In the present embodiment, because clear sheet and nontransparent sheet material do not form a sheet material, so do not need to detect their boundary line.So, also the boundary line detecting sensor can be installed.Therefore, it is same forming at the image of clear sheet that image with common paper used for recording forms.
Fig. 9 is the sectional drawing of schematic configuration of after-treatment device (laminating apparatus) of describing the image processing system of present embodiment.Forming the nontransparent medium 91 of adhesive layer, is to twist on the axle with the state of in accordance with regulations size severing.The peeling paper 92 of this nontransparent medium spool 90 is twisted on the peeling paper spool 94.At this moment, separating plate 93 strips down nontransparent medium 91 from peeling paper 92 with the curvature separation.In the front of hold-down roller 95, being provided with can be with transparent media 101 and nontransparent medium 91 detected sensors 111 and 112.According to the signal of this sensor, can in this attachment device, finely tune and make it to be harmonious to the front end of transparent media and nontransparent medium.
To the applying position of transparent media 101 and nontransparent medium, be provided with the guiding parts 96 that the position of nontransparent medium 91 is carried out regulation from position that nontransparent paper is stripped from, nontransparent medium 91 are by along guiding parts 96 guiding hold-down rollers 95.Because guiding parts 96 is by the spring pressurization of not drawing among the figure, perhaps this guiding parts is made of elastic body, so when powerful (drawing the power of hold-down roller) took place, guiding parts can be evaded, and does not hinder when compressing thus.
The fit-state of actual nontransparent medium is indicated among Figure 10-17.Leave the nontransparent medium 91 of separating plate 93, as the arrow portion of Figure 11, be in not by the state freely of regulation, so the applying angle θ 1 for Figure 10 becomes θ 3≤θ 1≤θ 2, the applying angle is various.By as shown in Figure 12, fitted with undesirable angle, and have bubble to enter.Therefore, as shown in figure 13, the setting angle (θ 4) by making guiding parts 96 is θ more than 2, and the applying angle becomes θ 1=θ 4, just can always obtain the applying angle stabilized thus, thereby avoid 2 medium to contact in undesirable position.
In addition, at this moment, as shown in figure 15, maintain static as guiding parts, when compressing with hold-down roller 95, nontransparent medium 91 not only carry out bending, and before pressurization, 2 medium contact, and like this, minute bubbles just enter easily.Thus, make as Figure 16 and Figure 17 and construct, promptly by the elastic force of spring pressurization or guiding parts, guiding parts is evaded to the direction of arrow A, D.This structure just can make backer roll pressurize in the direction of arrow B in holding part, and bubble will be forced out in the direction of arrow C, thereby has prevented entering of bubble.
In addition, above-mentioned embodiment is a preferred forms of the present invention, and the present invention is not limited to this.According to technological thought of the present invention, can carry out various variations.
For example, writing mode can not use laser, and is to use LED.Again for example, during development, do not use 2 component developers and use 1 component developer.Again for example, the photographic fixing means are not to use belt, but roll-type or induction heating.In addition, image forming mode also can not be the electrofax mode that present embodiment adopts, but the mode of ink-jet.
Further, though in first embodiment of the present invention, be that incorporate medium are folding, and the image of structure shown in formation Fig. 4 A and Fig. 4 B, but, also can with separately independently transparent media and nontransparent medium overlap, and form image as Fig. 4 A and Fig. 4 B.
