Abstract

PURPOSE:To obtain an excellent full-color image without requiring glue by uniting and pressing a photosensitive pressure-sensitive medium which is coated with a developer and a seal base material which has cohesive layers on both surfaces. CONSTITUTION:The microcapsule paper 4 which has a latent image and a developer layer 27 on the latent image and the base material seal 10 are put one over the other and pressed by a couple of developing rollers 13. Internal materials flows out of microcapsules with the pressure and react on the developer layer 27 to color. At the same time, the cohesive surface of the seal base material 10 contacts the developer layer 27 and is pressed. At this time, the cohesive strength operating between the developer layer 27 and seal base material 10 is much larger than the sticking force based upon the developer layer 27 and microcapsule paper 4, so the coloring internal materials and developer layer 27 are transferred to the seal base material 10. Consequently, the excellent full-color image can be obtained without requiring any glue.

Description

[Detailed description of the invention] [Industrial application fields] The present invention relates to a seal making device.

[Prior Art] Conventionally, so-called image forming apparatuses can be classified into electrophotographic methods, silver salt photographic methods, thermal transfer methods, etc. according to their methods. In the electrophotographic method, an image is formed on plain paper, so-called copy paper, in the silver salt photographic method, an image is formed on photographic paper, and in the thermal transfer method, an image is formed on plain paper with a surface smoothing process. On the other hand, there is also a strong demand for forming images on rigid bodies such as video cassettes/slot cases, file covers, glass, etc., rather than paper. It is obvious that the image forming apparatus described above cannot directly form an image on a rigid body, so as a method to meet the above requirements,
After forming an image on a specified paper, you can apply glue or the like to the back of the image side of the paper and attach it to a rigid body, or you can form an image on a sticker paper that has adhesive on the back side in advance and attach it to a rigid body. A pasting method is used.

[Problems to be Solved by the Invention] However, the former method requires the labor and effort of applying the glue, and has the disadvantage that the glue creates unevenness on the image surface, making the image unsightly. Regarding the latter method, if you try to implement it using electrophotography, the sticker paper is thicker and more rigid than normal copy paper, so toner cannot be transferred well, and the adhesive part of the sticker paper is difficult to transfer to the heat fixing device. There are problems such as sometimes melting. Furthermore, in the silver halide photographic system, there were problems such as damage to the adhesive portion of the sticker paper by the developer-fixing solution. The only thermal transfer type image forming apparatus is capable of printing in black and white or multicolor on sticker paper, but it is impossible to obtain a good full-color image with this type of image forming apparatus.

The present invention was made in order to solve the above-mentioned problems, and an object of the present invention is to provide a seal manufacturing device that can obtain good full-color images and does not require glue.

[Means for Solving the Problems] In order to achieve this object, the image forming apparatus of the present invention includes a latent image forming means for forming a latent image based on image information on a photosensitive pressure sensitive medium, and a latent image forming means for forming a latent image on a photosensitive pressure sensitive medium, and a device on which the latent image is formed. A developer applying means for applying a color developer to the photosensitive pressure-sensitive medium coated with the color developer, the photosensitive pressure-sensitive medium coated with the color developer, and a sealing base material having adhesive layers formed on both surfaces are integrated and pressurized. It consists of a pressure developing means.

[Operation] In the seal manufacturing apparatus of the present invention having the above configuration,
A latent image based on the image information is formed on the photosensitive pressure sensitive medium by the latent image forming means, a color developer is applied by the color developer application means to the photosensitive pressure sensitive medium on which the latent image is formed, and the color developer is coated with the color developer. The applied photosensitive pressure sensitive medium and the sealing base material having adhesive layers formed on both sides are integrated and pressed by a pressure developing means. The latent image on the photosensitive pressure sensitive medium is developed and transferred to the seal base material.

[Example] Hereinafter, an example embodying the present invention will be described with reference to the drawings.

The drawing is a schematic diagram of a seal manufacturing apparatus 1 embodying the present invention. At the top of the seal making device 1, a glass original table 8 for holding an original 7 and a cover 15 for bringing the original 7 into close contact with the original table 8 are provided. Also frame 1
There is a slit 1 at the top of document plate 7 at the bottom of document table 8.
8 is provided. Inside the frame 17 , the microcapsule paper 4 fed out from the feeding roller 2 is fed by a guide roller 11 , an electrode roller 12 , and a developing roller 13 and is wound around a winding roller 3 . Below the document table 8 and above the microcapsule paper 4 is an exposure light source 5 for exposing the microcapsule paper 4.
and an imaging lens 6, and an electrode roller 12.
A color developer coating unit 20 is provided on the left side of the color developer coating unit 20 .

The developer application unit 20 includes a case 25, a developer carrying roller 21, a developer supply roller 22, and an agitator 23 provided inside the case 25, and further includes a particulate developer 26.
is stockpiled. A power source E is connected to the electrode roller 12 and has a potential of about 1 kV, and an electric field is formed between the electrode roller 12 and the grounded developer carrying roller 21. Further, at the bottom of the apparatus, the sealing base material 10 fed out from the feeding roller 9 is placed on the developing roller 13. It is configured to be output to the outside of the device through guide rollers 14. Further, the seal base material 10 is a seal member 10 with adhesive applied on both sides.
A and a release paper 10b pasted on the lower surface thereof.

Next, the action will be explained.

First, the feed roller 2 and the take-up roller 3 are driven by a drive device (not shown), and the microcapsule paper 4 is conveyed in the direction of the arrow in the figure. Subsequently, the document table 8 holding the document 7 moves in the left-right direction in the figure, and the exposure light source 5
lights up. The light emitted from the light source 5 passes through the slit 18, passes through the glass of the document table 8, and reaches the document 7. The reflected light from the original 7 passes through the slit 18 and enters the frame 17.
The microcapsule paper 4 is then returned to the inside of the microcapsule paper 4, and an image is formed on the microcapsule paper 4 by the imaging lens 6. Original table 8 and microcapsule paper 4
Since these move in synchronization, a latent image corresponding to the original 7 is formed on the microcapsule paper 4. The microcapsule paper 4 on which the latent image has been formed is conveyed to the position of the electrode roller 12. In the developer application unit 20, the stirrer 23, the developer supply roller 22, and the developer carrying roller 21 rotate, and the developer 26 is applied to the developer carrying roller 21.
is carried. The color developer 26 flies from the color developer support roller 21 toward the electrode roller 12 due to the electric field formed between the electrode roller 12 and the color developer support roller 21 . Therefore, a color developer layer 27 is formed on the microcapsule paper 4 wrapped around the electrode roller 12. Furthermore, the microcapsule paper 4 runs in the direction of the arrow, and the pair of developing rollers 1
Reach between 3 and 3. Here, the sealing base material 10 is taken out from the delivery roller 9 and sent between the pair of developing rollers 13. The microcapsule paper 4 on which a latent image is formed and the color developer layer 27 is formed on the latent image, and the base seal 10 are overlapped and pressed by a pair of developing rollers 13 . Here, since there are capsules that are destroyed by pressure and capsules that are not, the contents flow out from the microcapsules in response to the latent image, react with the color developer layer 27, and develop color. At the same time, the adhesive surface of the sealing base material 10 comes into contact with the color developer layer 27 and is pressurized. At this time, the adhesive force between the color developer layer 27 and the sealing base material 10 is greater than the adhesive force between the color developer layer 27 and the microcapsule paper 4.
Since the adhesive force acting between the adhesive surface and the adhesive surface is much greater, the colored inclusions and the color developer layer 27 are transferred to the sealing base material 10. The sticker with the image formed in this way is output to the outside of the frame 17 of the device. A release paper 10b is pasted on the back of the image side of this sticker, but if you peel it off, you will get an adhesive surface, so you can use paper, cloth, plastic, etc.
Can be glued to anything including glass and wood.

As is clear from the above detailed description, the seal producing apparatus 1 of the present invention can obtain a good full-color image and does not require glue.

Note that the present invention is not limited to the embodiments described above, and changes can be made without departing from the spirit thereof. For example, as a means of applying a color developer, it is possible to apply an adhesive component or moisture to the latent image area of microcapsule paper, sprinkle powder of the color developer on it, and then overlap it with the sealing base material and pressurize it. good.

[Effects of the Invention] As is clear from the detailed description above, the seal production apparatus of the present invention can obtain a good full-color image,
And does not require glue.
