JPH0720734B2 - How to create a counterfeit prevention form - Google Patents

Description

TECHNICAL FIELD The present invention relates to a method for creating various forms such as securities, depositary receipts in financial transactions, and refund payment notices, and more particularly to a desired method of printing on a non-impact printer. The present invention relates to a form creation method capable of preventing counterfeiting by visually recognizing falsification of transmitted information.

2. Description of the Related Art Conventionally, in the case of an impact printer, decoloring ink that develops a color by causing an ink erasing and a chemical reaction is used as a means for easily visually recognizing tampering of transmission information printed by a printer on various forms. It is known. However, in the case of a toner-fixing type non-impact printer, it is impossible to use decolorable ink because ink cannot be used.

Problems to be Solved by the Invention Although a general non-impact printer displays toner transfer information by fixing toner, the transferred transfer information is tampered with because the fixed toner is easily peeled off by rubbing. There is a possibility that this alteration cannot be visually recognized. For this reason, there has been a demand for the development of a form capable of easily visually recognizing the falsification of transmitted information printed by a non-impact printer, but there is no one that can respond to this.

The present invention has been made in order to meet this demand, and it is possible to easily visually recognize tampering with desired transmission information obtained by fixing and printing toner with a non-impact printer.
It is an object of the present invention to provide a method for creating a forgery prevention form that can prevent forgery.

Means for Solving Problems A thermosensitive color-developing layer that develops color when a predetermined temperature is applied is provided on at least a part of the form surface, and a non-impact printer that fixes the toner on this thermosensitive color-developing layer by flash method is used. , Preferably by melting at a temperature higher than the coloring temperature of the heat-sensitive color developing agent layer, by using a toner having good heat absorption to display various transmission information such as amount and account number, and fixing by a flash fixing method, The same transfer information as the transfer information displayed by the toner is color-displayed on the thermosensitive color developing agent layer located immediately below the fixed toner.

Even if the toner fixed on the form is scraped off, the same transmission information is displayed in color on the thermosensitive color developing agent layer.Therefore, this display is also erased and the new transmission information is mistaken for the toner indication. It is difficult to display the information so that it can be easily visually recognized when the transmission information of the form is falsified, so that the forgery of the form can be prevented.

Examples Hereinafter, preferred examples in which the present invention is applied to a deposit certificate issued at the time of application for stock certificates, corporate bonds, etc. will be described in detail with reference to the accompanying drawings.

Here, Fig. 1 is a plan view of the created receipt, and Fig. 2
FIG. 4 is a partial cross-sectional view showing the formation of transmission information on a receipt, FIG. 3 is a schematic explanatory view of a non-impact printer, and FIG. 4 shows a receipt in a continuous state before printing by the non-impact printer. It is a top view.

First, referring to FIG. 4, a deposit certificate before printing with a non-impact printer will be described. The deposit certificate 1 is provided with a plurality of marginal portions 3 each having a transfer hole 2 on both sides thereof, and a large number of them are continuously provided via a perforation 4 for cutting. And
On the front surface of the bill of deposit 1, each display unit of an address display unit 5, an account number display unit 6, an application number display unit 7, a unit price display unit 8 and a total amount display unit 9 is displayed in a blank state. .

Next, based on FIG. 1 to FIG. 3, a deposit certificate 1 capable of preventing forgery by printing desired transmission information on the deposit certificate 1 by a non-impact printer linked to a computer (not shown). How to create is explained.

First, as shown in FIG. 2, a thermosensitive color developing agent layer 10 that develops color when heated at a predetermined temperature is provided at a portion corresponding to each display portion 5, 6, 7, 8, 9 on the surface of the receipt 1 , Provide a slightly wider area than the printed area. The thermosensitive color developing agent layer 10 is preferably selected such that the color forming temperature thereof is lower than the fixing temperature of the toner to be described later, for example, about 110 ° C. to 120 ° C.

Subsequently, the deposit receipt 1 in which the thermosensitive color developing agent layer 10 is provided in a predetermined portion is placed on the paper feeding section 12 of the known non-impact printer 11 shown in FIG. 3, and the pair of rolls 13a is placed. ,
The transfer hole 2 is engaged with the tractor belt 14 stretched around 13.

Then, when the non-impact printer 11 is operated,
After the photosensitive drum 15 is uniformly charged by the pre-charger 16, the computer issues a signal corresponding to the transmission information to be displayed on each of the display units 5, 6, 7, 8 and 9, and in response to this signal. A semiconductor laser beam is emitted from the optical unit 17 to the photosensitive drum 15. As a result, the charges on the surface of the photosensitive drum 15 are eliminated only in the laser light irradiation portion,
On the surface of the photosensitive drum 15, the transmission information to be displayed is characters,
It is formed as an electrostatic latent image patterned into numbers, signals and the like. When the electrostatic latent image passes through the developing device 18, the electrostatic latent image is visualized by adhering toner made of black resin powder having good heat absorption of flash light energy. Then, the transfer information 21, which is a toner image on the surface of the photosensitive drum 15 that has been visualized, is transferred to the transfer unit 19 by the predetermined display units 5, 6, 7, of the deposit certificate 1 transferred by the tractor belt 14. Transferred onto the thermosensitive color developing agent layer 10 corresponding to 8 and 9 (see FIG. 2).

The deposit certificate 1 is further fixed by a tractor belt 14 to a fixing unit.
When the toner is transferred to the toner container 20, where the xenon lamp 20a emits light, the toner with good heat absorption of flash light energy absorbs heat of its melting temperature of about 130 ° C. and is instantly melted, and the toner The image-transmitted information 21 (see FIGS. 1 and 2) is fixed on the receipt 1 and printing is completed. At this time, as shown in FIG. 2, in the heat-sensitive color developing agent layer 10, only the heat-sensitive color developing agent layer 10a in a portion corresponding to directly below the transfer information 21 which is a toner image is sufficient for developing the color of the heat-sensitive color developing agent. Color develops in response to heat of about 130 ° C absorbed by the toner, which is the temperature.

In this way, the transmission information 21 is composed of the fused and fixed toner image and the colored thermosensitive color developing agent layer 10a immediately below the toner image.
Displayed on each display 5, 5, 6, 7, 8 and 9 of the receipt 1 in double top and bottom,
The deposit receipt 1 on which the printing is completed is sequentially stacked on the stacker unit 22.

On the other hand, the toner remaining on the photosensitive drum 15 without being transferred to the deposit certificate 1 is, as shown in FIG.
The toner is removed at 23 and collected in a toner collecting system (not shown).

By repeating the above operation, the desired transmission information input to the computer is sequentially and continuously printed on each display section 5, 6, 7, 8, 9 of the receipt 1 in the continuous state. is there. Then, if the marginal portion 3 of the deposit certificate 1 in a continuous state is cut off and cut off at the perforations 4 for cutting, the desired transmission information is displayed on the respective display parts 5, 6, 7, 8, 9 shown in FIG. The deposit certificate 1 with 21 printed is completed.

Even if the transmission information 21 formed by fusing and fixing the toner image is scraped off,
Since the same content is color-displayed on the thermosensitive color developing agent layer 10, it is difficult to delete the transmission information displayed in color and display new transmission information so that it can be mistaken for display by toner. is there.

The present invention is not limited to the above-mentioned embodiments, and for example,
The heat absorption of the flash light energy is absorbed only in the toner portion and the flash light irradiated to other portions is reflected. Therefore, the heat-sensitive color former layer 10 may be provided on the entire surface of the deposit certificate 1. , The temperature of the toner and heat-sensitive color former 10 is 130 ℃
Fixing at a temperature of about 110 ° C. to 120 ° C., the temperature of the heat-sensitive color developing agent is not lower than the fixing temperature of the toner, and various selections can be made according to the light emission temperature of the fixing unit 20. The fixing temperature of the toner and the color forming temperature of the thermosensitive color developing agent may be about the same. Furthermore, it is needless to say that it can be applied to various forms other than the deposit certificate 1.

As is apparent from the above description, according to the present invention, even if the transmitted information displayed by the toner fixed on the form is scraped off, the same content is obtained in the thermosensitive color developing agent layer located immediately below it. Since the transmission information is displayed, it is difficult to delete the transmission information displayed in color and display the new transmission information so that it can be mistaken for the display by toner, and the transmission information on the form is tampered with. If it is done, it is possible to visually recognize it easily, and thus it is possible to prevent the forgery of the form.
