Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic intermediate method characterized in that a sublimable toner image formed on electrostatic recording paper is transferred onto the surface of a commuter pass or the like by heating.

Electrostatic recording is capable of extremely high-speed recording of several microseconds per dot or less and provides high recording density, and is currently being put into practical use as a medium-sized device for facsimiles or computer terminals.

However, in the electrostatic recording method, as shown in FIG.
In order to perform electrostatic recording on the face of a ticket, special processing must be applied to the ticket paper. That is, in FIG. 1, 2 is a plastic substrate, 3 is a low-resistance layer made of low-resistance zinc oxide, etc., and 4 is a plastic substrate.
5 is a dielectric layer coated thereon, which functions as a holding layer for electrostatic charge images, and 5 is a magnetic recording layer. Thus, in the conventional ticket paper 1, at least. Providing the low-resistance layer 3 and the dielectric layer 4 is essential for the recording principle, and has been a cause of increased running costs. Furthermore, the conventional ticket paper 1 having the structure shown in FIG. The dust had been scraped off by friction, causing a moderate concentration drop or staining the ticket gate. The present invention was made to eliminate the above-mentioned conventional drawbacks, and provides a medium method that does not require any special processing of ticket paper and has extremely high abrasion resistance.

This invention will be explained below. FIG. 2 shows a basic configuration diagram for explaining the intermediate method according to the present invention.

In this invention, the ticket paper 11 is simply made of a plastic substrate 11A made of vinyl chloride, polyester, polyethylene terephthalate, etc. and a magnetic recording layer 11B, as shown in FIG.
It is made up of layers. The process of placing the paper on the ticket paper 11 is carried out according to the following steps. That is, the electrostatic recording paper 13 consisting of the low resistance base paper 13A and the dielectric layer 13B shown in FIG.
The dielectric layer 13B is pressed by the pressure roller 15 so as to be in contact with the dielectric layer 13B, and is fed in the direction of the arrow in the figure. Then, a signal voltage Vs applied to the electrostatic recording head 14 by the signal power source 16 forms a charge image on the dielectric layer 13B based on the well-known principle of electrostatic recording. Note that the electrostatic recording paper 13 used here can be a commercially available ordinary electrostatic recording paper cut to about the width of the ticket paper 11 (~60T!r!n) and can be used as is. The electrostatic recording paper 13 on which the charge image has been formed is developed into a toner image by a toner developing device 17. In this invention, the properties of the toner used as a developer are important, and at least the toner has sublimation properties, such as Sumikalon Violet 3BL,
It is necessary to contain dyes such as Diamond Navy Blue ER-FS, Oraset Blue B, and Oil Black FBB. The electrostatic recording paper 13 on which a toner image containing such a sublimable dye has been formed is transferred to the plastic substrate 11A of the ticket paper 11 by a heating roller 18 and a pressing roller 19.
is pressed into contact with the toner image. heating roller 1
8 and presser roller 19 while being moved while being pressed, the sublimable dye is sublimated and transferred to the ticket paper 11, and the sublimable dye generally has the ability to penetrate into plastic materials under high temperature conditions. Therefore, when vinyl chloride, which has high permeability, is used as a substrate, it penetrates into the plastic in a short time, and after cooling, it is fixed as a dye image that penetrates into the plastic. In this way, printing on the ticket paper 11 is completed, but the formed recorded image is simply printed on the plastic substrate 11.
In addition to being placed on A, the plastic substrate 11A
Since it penetrates into the inside of the ticket paper 11, the printed image does not disappear due to mechanical friction on the surface of the ticket paper 11, so it is possible to obtain a commuter pass with extremely excellent wear resistance. On the other hand, the electrostatic recording paper 13 after use is taken up by a take-up roller 20 and discarded. Although this invention basically consists of a combination of electrostatic recording paper 13 and ticket paper 11 as a transfer medium, many variations are possible as will be explained in detail in the following embodiments. FIG. 5 shows another embodiment of the invention.

In the embodiment shown in FIG. 2 described above, the process transition from recording to development to transfer was based on the movement of only the electrostatic recording paper 13.
In the embodiment shown in FIG. 5, the electrostatic recording paper 13 is held inside a cylindrical drum 21, and is moved as a saw body by rotating the cylindrical drum 21. And ticket paper 11
A portion corresponding to the area is exposed to the outside of the light-transmitting portion 22 such as a glass plate. The electrostatic recording paper 13 on which a toner image has been formed after passing through the recording head 14 and the toner developing device 17 is pressed against the ticket paper 11 by a presser roller 19 . By lighting the infrared lamp 23 at this position, a highly abrasion-resistant print is made on the ticket paper 11 in the process described above. After use, the electrostatic recording paper 13 is transferred to the take-up roller 20 for 11 minutes of the ticket paper.
The new surface is exposed to the light-transmitting portion 22 again, and recording is performed repeatedly. Then, when the electrostatic recording paper 13 previously wound around the holding roller 12 runs out, the used roll paper is discarded and a new roll paper is set. Note that the ticket paper 11 has a plastic substrate 11A and a magnetic recording layer 11.
B, but as shown in FIG. 4, a permeable layer 11C made of soft vinyl chloride, which has excellent permeability to dyes, is laminated on a plastic substrate 11A made of polyethylene terephthalate, etc., as shown in FIG. You may also use a laminated ticket paper 1'' like this.

Furthermore, the plastic substrate 11A is not limited to plastic.
For example, it may be made of paper or wood, and in this invention, the ticket paper 11
is not limited to specific materials. Furthermore, the materials of the toner used can be roughly divided into those that contain magnetic fine powder in the toner itself and those that are mixed with iron powder that contains magnetic fine powder, but this invention is not limited to these. It's not something you can do.

Further, for the purpose of the present invention, the effect is most exhibited when the toner contains a sublimable dye, but when the ticket paper 11 does not require abrasion resistance, or when the ticket paper 11
If paper or the like is used, sublimation is not necessarily required, but the toner may be meltable and have a composition that allows at least a portion of the toner image to be transferred from the electrostatic recording paper 13 to the ticket paper 11. , all available. In this invention, these properties are collectively referred to as sublimation toner. Furthermore, although the above embodiment has been shown only when used in a commuter pass issuing machine, the printing method of the present invention can be similarly used in credit card issuing machines, ticket issuing machines, facsimile machines, computer printers, etc. . As explained in detail above, the present invention develops a charge image formed on electrostatic recording paper with sublimable toner, and heats the transfer medium while pressing the electrostatic recording paper on which the sublimable toner image has been formed. By doing so, transfer and sublimation are performed at the same time by thermo-pressure welding,
This is a printing method in which a sublimation dye image is transferred onto or into the transfer medium so that a portion of the image permeates into the transfer medium.
The process is simple, there is no need for a corona charger for electrostatic transfer, and since electrostatic recording paper is disposable, there is no need for a cleaning mechanism for residual toner. The medium can be configured with only a magnetic recording layer and a plastic substrate, which has the advantage of lower running costs and transfer with extremely high wear resistance.
