DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. In FIG. 1, reference numeral 11 denotes a facsimile for receiving a request for the creation of a seal imprint from a seal shop or the like.
1, an order document 12 indicating the size, inner diameter, type of character, thickness of character and the like of the stamp material arrives. Reference numeral 13 denotes a seal imprinting device constituted by a personal computer or the like. Reference numeral 16 denotes a facsimile communication device connected to the seal imprinting device 13, which transmits the seal imprint created by the seal imprinting device 13 to a remote facsimile 18 such as a seal shop via a communication (telephone) line 17. The facsimile 18 of a seal shop or the like is of a thermal type, and prints a seal imprint sent from the seal imprinting device 13 on a thermal paper 19.

Reference numeral 21 denotes a copying machine which is used to copy the imprint of the thermal paper 19 onto plain paper 22. As the copying machine 21, for example, a copying machine of an indirect electrostatic transfer system is used. This indirect electrostatic transfer type copying machine reads the distribution of light and darkness of an original, and fixes colored fine particles called toner on a transfer medium (such as plain paper) to simulate the distribution of light and darkness similar to that of an original. The original is transferred. Reference numeral 23 denotes an oily liquid such as sewing machine oil.
2 for making an original 24 for an engraving machine by making an oily liquid impregnated and making it translucent.

Reference numeral 26 denotes a photoelectric engraving machine,
7 and 28, the stamp material is set on one of the rotary tables 27, and the original 24 for the engraving machine is set on the other rotary table 28. 28 for engraving machine on 28
4, the light passing through the engraving machine manuscript 24 is received by the microscope 29, whereby the engraving machine manuscript 24 is received.
The presence or absence of a seal is detected for
7. The engraving rotary drill 30 arranged above is moved up and down in accordance with the presence or absence of the imprint detected by the microscope 29, whereby the rotary drill 30 engraves the stamp material as displayed on the engraving machine original 24. It has become.

Next, steps from creation of the engraving machine original 24 to engraving of the stamp material will be described with reference to FIG. The imprint creation request arrives at the facsimile 11, and the imprint is printed on the order manuscript 12. Based on the request for creating the order manuscript 12, the seal imprinting device 1 is operated by input from the keyboard 14 or the like.
Step 3 creates an imprint. At this time, imprint the facsimile 18
Create a seal imprint so that it will have the dimensions of the creation request when printed with.

That is, a facsimile expresses an image as a group of fine points. That point is 200 points per inch in the case of the fine mode of the G3 standard. To convert the actual dimensions into facsimile scores, use the following formula. Facsimile points = actual dimensions (mm) × 200 (resolution) /25.4 (value measured for 1 inch in mm) The above formula also incorporates a formula for converting inches to millimeters, and 1 inch is approximately It is calculated as 25.4 mm. For example, when the size of 10 mm is converted into the number of facsimile points, 10 × 200 / 25.4 = 79 (rounded down to the decimal point), which is 79 points. Therefore, since the display device on the screen 15 of the seal imprinting device 13 also expresses the image as a group of fine points, when the seal imprint is created with the number of points calculated by the above formula and printed by the facsimile 18, the imprint is performed in the desired size. Is obtained.

When roll paper is used as the thermal paper 19 of the facsimile machine 18 as shown in FIG. 2, the actual size of the printed material is reduced by the accuracy of the roll paper feeder and the wear of the paper feed rollers. And an error comes out. Therefore, the imprint is created by correcting this error. That is, when printing an imprint on the thermal paper 19 using roll paper, the printing tends to expand in the vertical direction Y and shrink in the horizontal direction X. Then
As shown in FIG. 3, the seal 32 created by the seal creating device 13 is created such that the vertical direction Y is 10 × 0.985 mm and the horizontal direction X is 10 × 1.01 mm.

Further, when engraving an imprint on a stamp material by the engraving machine 26, the imprint created by the imprint creation device 13 must be reversed left and right in advance. In the case of producing a positive film as in the prior art, the imprint could be reversed left and right by inverting the front and back of the positive film and placing it on the engraving machine 26, but in the present invention, the original 24 for the engraving machine was copied by the copying machine 21. To impregnate oily liquid 23 into plain paper 22
Since the toner adheres to the surface of the plain paper 22, it cannot be turned upside down. Therefore, the seal imprinting device 13
Is created by inverting the seal imprint left and right in advance.

Since the photoelectric engraving machine 26 irradiates light from under the original 24 for the engraving machine and detects the amount of transmission of the light as described above, the engraving is performed. The less (blurred) the lower the accuracy of the sculpture. Therefore, when the toner surface is turned down as shown in FIG. 4, the amount of light from the light source greatly changes between a portion where the toner is present and a portion where the toner is not present, thereby sharpening the boundary between light and dark. When the light of the engraving machine original 24 passes through the paper and causes irregular reflection, and the light goes out of the paper, the difference in the amount of light becomes small and the boundary is blurred. On the other hand, when the toner surface is turned up as shown in FIG. 5, the light irregularly reflected in the paper is selected after coming out of the paper, so that the difference in the amount of light becomes large, and the boundary between light and dark is increased. Because it becomes clear.

Next, the seal imprint created by the seal imprinting device 13 is transmitted by the facsimile communication device 16 to the communication (telephone) line 17.
To a facsimile machine 18 such as a seal shop located in a remote place. This facsimile communication device (modem) 16
It has a function of controlling the communication line 17 and a function of converting an analog signal into a digital signal. The communication line 17 is controlled by an instruction from the seal imprinting device 13 so that it can communicate with the facsimile 18 such as a seal shop. Send. However, since the receiving side at this time is the facsimile machine 18, the imprint transmitted by the facsimile communication device 16 (modem) is converted by the imprint creation device 13 into a form that can be handled by the facsimile device 18, and then transferred to the facsimile communication device 16. I have.
That is, after converting the data format of the seal imprint created by the seal imprinting device 13 to match the data format of the facsimile 18 by software, the data is converted to the facsimile communication device 16.
The data is further converted from a digital signal to an analog signal by the facsimile communication device 16 so as to be placed on the communication line 17, and the facsimile 18 at the seal shop side is transmitted via the communication line.
Send to

The format that can be handled by the facsimile is
MH code (Modified Huffman code)
e) or MR code (Modified Read code)
It is determined by the CCITT recommendation in a format called e). Therefore, the seal imprinting device 13 converts the seal imprint by the MH encoding method. Then, the imprint sent from the imprint creation device 13 by the facsimile machine 18 such as a seal shop is transferred to the thermal paper 19.
And imprint the imprint of the thermal paper 19 on the plain paper 2 by the copying machine 21.
Copy to 2. Then, the plain paper 2 copied by the copying machine 21
2 is impregnated with an oily liquid 23 so as to be translucent to prepare an original 24 for an engraving machine. The reason that the oily liquid 23 is impregnated into the plain paper 22 is that the photoelectric engraving machine 26 cannot be engraved unless it is under a plate that transmits light. is there. This liquid is required to be slow in drying and to have little expansion and contraction of the impregnated paper in addition to facilitating transmission of light. An oily liquid, particularly a sewing machine oil, is suitable for satisfying this condition. When the paper is the facsimile thermal paper 19, the printed matter disappears, so that the copy content of the thermal paper 19 is transferred to the plain paper 22 by the copying machine 21.

It is to be noted that the seal imprint is prepared by enlarging the seal imprint in advance by the seal imprinting device 13 and, when the seal imprint of the thermal paper 19 is copied onto the plain paper 22, the quality of the seal imprint is improved. After that, the stamp material 33 is set on one of the rotary tables 27 of the photoelectric engraving machine 26 and the other rotary table 28 is set.
The original 24 for the engraving machine is set thereon, and the stamp material is engraved with the rotary drill 30 as indicated on the original 24 for the engraving machine.

FIG. 6 shows another embodiment, in which a seal imprint sent from the seal imprinting device 13 is directly printed on plain paper 35 in place of the heat-sensitive facsimile 18 at the seal shop side. In this case, the copying of the seal imprint on the plain paper 22 by the copying machine 21 is omitted, and the plain paper 35 printed by the facsimile 18 is impregnated with the oily liquid 23 to be translucent to prepare the engraving machine manuscript 24. I do. Otherwise, the original 24 for the engraving machine is produced in the same procedure and method as in the above embodiment.
And engrave the stamping material.

[0021]

According to the present invention, the preparation of a positive film and the mailing of the positive film to a stamp shop or the like can be omitted, and the manuscript 24 for an engraving machine can be prepared in a very short time without any trouble. . In addition to eliminating the need for development and other equipment,
The original 24 for the engraving machine can be created at low cost by using facsimile communication.

Further, the quality of the imprint is improved by enlarging and creating the imprint in advance by the imprint creating device 13 and reducing and copying the imprint on plain paper 22 when copying the imprint by the copying machine 21. Thus, it is possible to create the engraving machine original 24 with higher accuracy. Further, by using a sewing machine oil as the oily liquid 23, it is possible to prepare a more suitable original 24 for an engraving machine, which has good light transmission, is slow in drying, and has little expansion and contraction of paper.
