DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marking processing printer having a function of printing a divided pattern of a seal as if a marking were made on two sheets of paper.

[0002]

2. Description of the Related Art With the development of printers, various types of data have been transferred from a host computer to a printer to perform printing processing. For example, by transferring image information such as a line drawing constituting a certificate or a bit pattern representing the certificate itself from the host computer to the printer, these printings can be easily performed. By attaching a logo such as a company emblem or a company trademark to such documents such as certificates, it can be ensured that the source of the documents is correct.

It has been conventionally proposed to print such a logo mark at a predetermined position on a document. For example, the portion other than the logo is printed by the electrostatic recording method using black toner in the same manner as a normal copying machine, and the logo is printed using a printing means such as a thermal transfer printer. By using color and printing over this paper, it is possible to have an effect as if stamped.

[0004]

By the way, it is not enough to simply print the logo on the document in order to determine that the document to be issued has exactly the same content as a certain document. . Therefore, in such a case, an original document and a duplicate document are conventionally created as documents having the same contents, and these are marked. This is because if two documents are brought together and the position where the seal is divided is confirmed, it can be confirmed that both are a pair of documents.

[0005] However, it has been said that such a marking cannot be performed by a printer. Of course, preparing two patterns after the seal is divided, and printing these at predetermined positions on each sheet,
This is possible with conventional techniques. However, if such a method is adopted, the pattern after the stamp is divided is fixed, and these patterns can be easily copied, and as a result, the forgery of the certificate can be easily performed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a marking printer which can perform a marking process for effectively preventing forgery of a document.

[0007]

According to the first aspect of the present invention, a seal pattern storing means for storing a seal pattern as a bit pattern of a seal to be stamped, and a random dividing position every time the seal pattern is stamped. The stamp processing printer is provided with a stamp pattern dividing means for dividing the two stamp patterns into two at the corresponding positions on two sheets to be marked. .

That is, according to the first aspect of the present invention, the stamp pattern is divided into two at random dividing positions each time stamping is performed , and these are printed at the corresponding positions on two sheets to be marked. since it was decided, tally impression
Each time is performed, the marking is executed with various changes, and forgery of the document can be effectively prevented.

According to the second aspect of the present invention, there is provided a seal pattern storing means for storing a seal pattern as a bit pattern of a seal to be stamped, and a random number generating means for generating a random number within a predetermined numerical range determined by the size of the seal pattern.

The host computer 11 stores a stamp pattern 22, a division mode designating signal 33, a print coordinate designating signal 34, and print data 24 in storage means (not shown). The stamp pattern 22 is transmitted from the host computer 11 to the stamping printer 12 before the stamping process is executed.
To be stored in the stamp pattern memory 23 (step S101). Normally, if these are registered in advance, such as a mark of a company representative, there is no need to transmit them to the marking processing printer 12 when printing individual documents.

On the other hand, the print data 24, the division mode designating signal 33, and the print coordinate designating signal 34 are information relating to the individual print contents and the specific form of marking when printing is performed. Is transmitted to the marking processing printer 12 when printing is performed. First, division of the stamp pattern stored in the stamp pattern memory 23 into upper and lower or left and right is determined in accordance with the division mode designation signal 33, and the stamp pattern is divided into two at a division ratio designated by a random number. (Step S102). Then, these are stored in the corresponding ones of the first and second divided memories 41 and 42 (step S103). Then, finally, print data of normal characters and the like and printing of a seal pattern are performed using the print coordinate designation signal 34 and the print data 24 (step S104). At this time, the coordinates of the printing position of the stamp pattern are specified by the printing coordinate specifying signal 34, and printing is performed in the recording color specified by the operation panel 55 (FIG. 3).

FIG. 5 shows a flow of operations from the transmission of predetermined data to the execution of the image processing for the marking after the marking processing is performed by the marking processing printer. The CPU 51 of the marking processing printer monitors whether data transmitted at the time of printing, such as the print data 24, from the host computer 11 via the interface unit 21 has arrived (step S201). When these data arrive (Y), the division mode designating signal 33 among them is decoded (step S202), and the vertical or horizontal division of the designated seal pattern is determined. Next, using the random number generator 36, a random number having a numerical value of the division ratio of “25” or more and “75” or less is generated. Then, this value is set as R and the division position obtained from this is stored in the working memory 54 (step S203).

FIG. 6 is a view for explaining the dividing position when the stamp pattern is divided into right and left. In this figure, a seal pattern 61 indicated by the letters "logo" is composed of a rectangular image area having a coordinate origin (0, 0) and another point (X, Y) as a diagonal line. Here, the broken line X
Reference numeral ₁ denotes a position at which the stamp pattern 61 is divided into right and left. The division position X ₁ is obtained by the following equation (1) using a random number R.

[0023]

[0024] That is, if the X is "100", when R is "60", the division position X ₁ is "6
0 ", and the stamp pattern 61 is divided into right and left at the ratio indicated by the random number R.

FIG. 7 is for explaining the dividing position when the stamp pattern is vertically divided. Wherein the broken line Y ₁ indicates the position of dividing the stamp pattern 61 up or down. Division position Y ₁ by using a random number R obtained by the following equation (2).

[0026]

(Equation 2)

That is, assuming that Y is “100” and R is “65”, the division position Y ₁ is “6”.
5 ", and the stamp pattern 61 is vertically divided by the ratio indicated by the random number R. In principle, the random number R may be at least" 0 "and less than" 100 ". In this embodiment, a random number R having a numerical value of “25” or more and “75” or less is generated in order for the portion to appear as a certain shape.

The CPU 51 then sends a print coordinate designation signal 34
Is used to determine whether the position where the seal is to be printed is on the top, bottom, left or right of the sheet (step S204). This determination is made by comparing information about the size of the sheet on which printing is performed with the printing coordinates.

FIG. 8 shows how the stamp pattern is printed when the printing position is on the left side of the sheet. In this case, the right side portion 61 _R of the stamp pattern on the left side of the sheet 62 of the _first sheet is printed (FIG.

Then, then coordinates from coordinates _{(0,0) (X, Y 1} ) becomes the lower portion 61 _D of the rectangular area (stamp patterns up and stored in the second divided memory 42 (step S215) that.

FIG. 12 shows the principle of the process of printing on a sheet after the stamp pattern for the stamp is stored in this way. Here, a case is shown in which the marking is performed on the right side of the sheet as described with reference to FIG. The page memory 26 stores the host computer 11
An image of one page of a predetermined certificate is developed based on the print data 24 sent from FIG. Also, the left side portion 61 of the stamp pattern in the specified printing position by the first division in the memory 41 the print coordinate designation signal 34 at the right side of the page in association with the page memory 26 _L
Is developed as a bit pattern. More second divided memory 42, the right portion 61 _R of the stamp pattern in the specified printing position by the print coordinate designation signal 34 at the right side of the page in association with the page memory 26 is developed as a bit pattern.

[0038] In the print processing unit 31 performs printing on the first sheet of paper 71 ₁ with a bit pattern of the page memory 26, further of the stamp pattern with a bit pattern of the first divided memory 41 on the to print the left-hand portion 61 _L. Further, performs printing on a sheet 71 of the _second sheet with the bit pattern of the page memory 26, the second on further this
To print the right portion 61 _R of the seal pattern with a bit pattern of the divided memory 42. In this way, a signed certificate of two main copies is created.

FIG. 13 shows a flow of a printing process of a stamp pattern. First, the print control unit 59 receives the transfer of the bit pattern for one page of the certificate stored in the page memory 26, sends it to the multicolor printer 58, and transfers the contents to the _first sheet 621. Printing is performed in black (step S301). Next, the bit pattern of the first divided memory 41 is transferred, and is transferred to the operation panel 55.
Printing is performed in the color designated by (FIG. 3) (Step S
302). First paper 6 thus printed in two colors
2 ₁ is discharged to a discharge tray (not shown) of the multi-color printer 58 (step S303).

Subsequently, printing is performed on the second sheet. That is, black printing is performed on the _second sheet of paper 622 using the contents of the page memory 26 in the same manner as in step S301 (step S304), and the bit pattern of the second divided memory 42 is transferred. Is printed in the same color as the above-mentioned color designated for marking (step S305). Thereafter, the second sheet 62 ₂ which are printed two colors is discharged to the above-described discharge tray multicolor printer 58 (step S306).

In the embodiment described above, the printing color of the certificate is black, but it is obvious that the present invention is not limited to this. Although it was decided to perform the reading of the image information certificates such as separately from the page memory 26 with respect to the first sheet each sheet 62 ₁ and the second sheet 62 _2, once the readout of the two printing After that, the printing of the tally may be performed on each sheet.

In the embodiment, a random number generator is used to generate a random number specifying the division ratio of the stamp pattern. However, the operator may arbitrarily specify the division position. Also, not only the seal pattern division position,
The print density of the seal pattern is set by a random number, or a bit pattern of the stored seal pattern is combined with a diagram pattern representing blurring (imprinting) at the time of imprinting, and thereafter, this is divided into two patterns. For example, forgery of the indicia can be made more difficult by employing a method such as printing. In order to prevent counterfeiting forgery more effectively, print a different line drawing pattern in a printing color such as black, which is different from the printing color of the marking, or print the number of the printer that issued the marking at the printing position of the marking. It is also effective to do so.

[0043]

As described above, according to the first aspect of the present invention, the stamp pattern is divided into two at random positions each time the stamping is performed , and each is divided into the designated positions on two sheets of paper. Since printing is to be performed, the target of marking is determined according to the division pattern of the seal pattern, the marking principle of the printer, the toner used or the fixing mode, and the like.
Sheets of paper can be specified, and not only can the marking process be performed efficiently, but also counterfeiting of documents can be effectively prevented.

According to the second aspect of the present invention, since the division position of the stamp pattern is defined by a random number,
The division position is not specified. In addition, since the random number is generated by limiting the numerical range, it is possible to prevent a situation in which one of the divided stamp patterns is only a small part of the pattern and the pattern cannot be specified. It is possible to more effectively perform the matching of the obtained pattern. According to the third aspect of the present invention,
The stamp pattern dividing means changes the dividing position each time stamping is performed.
Can effectively prevent forgery of documents.
