Abstract

PURPOSE:To form a relief pattern smoothly and efficiently by a method wherein, processing position data is generated in the form of a relative coordinate data with a reference of a predetermined origin, and the pattern is continuously formed by cutting according to the relative coordinate data. CONSTITUTION:For example, a character 8 has a character origin O to its upper left-hand, which is determined to be positionally different from a mechanical origin, i.e. a home position, of a cutting device 9. All cutting processing is carried out on the basis of a relative coordinate with a reference of not the mechanical origin of the cutting device but the character origin O; in this manner, a character string including a series of two or more characters is also smoothly and continuously conducted on the basis of the relative coordinate with a reference of the character origin O. Namely, a point on upper left-hand of the character 8 close to the character origin O is determined as a processing start point Slu of 7B8LU, and from this start point Slu the left side of the character 8 is cut by a drill from upper to lower as shown by a heavy line 51. The processing is ended at an end point Elu on the lower center of the character 8.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a method for forming a raised pattern, such as a pattern such as a so-called embossed character, on the surface of an IC card, etc. .

(Prior Art) For example, the surface of a card such as an IC card, a credit card, or a magnetic card for a bank card has embossed characters (hereinafter referred to as ``embossed characters'') with the card number, expiration date, user's name, etc. Conventionally, such raised characters are formed by pressing a male and female mold that have the same character pattern as the raised characters by sandwiching the - card from both sides, thereby creating a card. The raised letters were formed by deforming the raised letters so that they protruded to one side.

However, with this method, it is necessary to form male and female molds corresponding to each raised character, and
Since the card itself is deformed to partially protrude to form raised letters, for example, by expanding the card function, especially the function of the 1'C card, the card surface can be used like a card type calculator. If the IC card itself is equipped with a numeric keypad, liquid crystal display, etc. to input and display information, it is possible to deform the card itself using male and female molds to form raised characters. Currently, in order to form raised characters on the surface of a card, raised characters are made of a plastic material such as vinyl chloride that forms the card and a material with physical characteristics such as hardened photopolymer, etc. A method has been considered in which a pedestal is laminated on the part of the card surface where raised characters are to be formed, and the laminated raised character forming pedestal is cut to match the raised characters to form raised characters.

<Problems to be Solved by the Invention> As mentioned above, when forming raised characters by cutting, conventionally, when the raised characters consist of a plurality of consecutive character strings, the spaces between each character are smoothly continuous. There is no processing technology available, requiring complicated and special control for each character, and the cutting process for each character may not be necessarily smooth and appropriate. This had become an issue.

The present invention has been made in view of the above, and an object of the present invention is to provide a method for forming a raised pattern in which cutting of the raised pattern can be carried out smoothly, continuously, and efficiently.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above object, the raised pattern forming method of the present invention includes processing position data of the raised pattern based on a predetermined origin related to the raised pattern. The gist is to generate the raised pattern using relative coordinate data, and to continuously form the raised pattern by cutting according to the relative coordinate data.

(Function) In the method for forming a raised pattern of the present invention, a raised pattern is continuously formed in accordance with processing position data consisting of relative coordinate data with respect to a predetermined origin related to the raised pattern.

(Example) Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 3 shows how raised characters 12 are formed by cutting the card base material 10 placed on the table 25 of the cutting device 9 with a drill 37. In the figure, rollJ is formed as a raised character 12.

Moreover, the raised characters 12 are on the surface of the card base material 10,
For example, a raised character forming base 10a is formed by curing photopolymer or the like, and a drill 37 cuts this raised character forming base 10a to form raised characters 12. In addition, cards such as IC cards usually have a three-line raised character string consisting of the card number, card expiration date, and card owner's name written in alphabets, but the card base shown in the figure Similarly, for 1o, three lines of raised character strings are formed.

Next, the main flowchart in Figure 6, Figures 7 to 1
The operation will be explained with reference to the detailed flowchart in FIG. 5 and the character string cutting explanatory diagrams in FIGS. 16 and 17.

First, explanation will be given with reference to FIG. 6(a'). Prior to cutting the raised characters, a cutting device 9 shown in FIG. 2 is used.
A card base material 10 as shown in FIG. 3 to be cut is placed on a table 25. Next, the power is turned on to the raised pattern forming device shown in FIG.
When the cutting device 9 operates, the spindle 31, which is the main axis, and the spindle 3
The drill 37 attached to the tip of the drill 37 starts rotating (step 110).

Then, the cutting device 9 is driven under control from the calculation unit 1 via the cutting position control unit 90, and the character origin O1 of the raised character string to be cut is, for example, shown in FIG.
The table 25 is controlled to be moved so that the drill 37 of the cutting device 9 is positioned above the character origin O at the upper left of the character string "01" shown in a) (step 120).

Note that, as described above, this movement is achieved by moving the table 25 in the horizontal X-axis and Y-axis directions via the moving table 29 or the like.

When the drill 37 is positioned above the character origin O of the raised character string "01" to be cut, the spindle 31 is lowered via the movable table 30, whereby the raised character string to be cut is removed from the tip of the drill 37. It is brought into contact or pressure contact with the surface of the pedestal 10a for forming raised characters on the card base material 10 to be formed (step 130).

Next, the first line (LINEI>, that is, the first line of the three lines of raised character strings formed on the card base material 10).
For example, the processing of the line (LINEI) is shown in Fig. 16 (a >
(Step 140). Note that the processing of this first line (LINE1) will be described in detail later with reference to FIG. 7.

When the machining of the first line (LINE1) is completed, the table 25 is controlled to move in the X-axis and Y-axis directions, and the drill 37 is moved above the contour starting point in order to cut the contour of the character string. (Step 150).

When the drill 37 moves above the contour starting point, the cutting process of the contour of the first line (L, INEl) is performed as shown in FIG. 16 (
f) (step 160). Note that the contour processing of this first line (LINE1) will be described in detail later with reference to FIG. 8.

1st line (LINEI> processing and 1st line (L
After completing the machining of the outline of INEL), the next step is to perform hollow machining, so first, the drill 37 is raised perpendicularly to the Z-axis direction and moved to the origin (step 170).

−Then check if there are any hollow characters (
Step 18o).

If there are no hollow characters, the process proceeds to step 210 in the flow of FIG.
The table 25 is moved so that 7 is positioned, and one character is hollowed out (Step 2 Q, O). Then, the process returns to step 1.80, and steps 180 to 200 are repeated until all hollow characters are processed. The repetitive operation of this hollowing process is shown in Fig. 1q (h),
In the case of a character string such as r0123.456J, the processing is performed by jumping from the processing end point of character 0 to the processing start point of character 6.

If there is no hollow character, or if the hollow character has been completely cut out, the process proceeds to step 210 in FIG.

The spindle 31 is lowered through 0, thereby lowering the tip of the little trill 37 onto the character origin O of the second line (L, I N F 2 ) of the raised character string to be cut (step 220). .

Next, the upper part processing, right space processing, lower part processing, and ■ of the second line (LjNE2) are performed in sequence (step 23

Then, it is checked whether the single hollow character is red or not (step 270). If there is no hollow character, the 6th
Proceed to step 3.00 of the flow in Figure (C), but if there is a hollow character, proceed to step 280, move the table 25 so that the drill 37 is located at the starting point of the hollow character, and move one character. (Step 290)
). Then, the process returns to step 270 and steps 270 to 290 are repeated until all hollow characters are processed.

Move to the character origin O of LINE3). Then, the spindle 31 is lowered via the moving table 30, thereby lowering the tip of the drill 37 onto the character origin O of the third line (LINE 3) of the raised character string to be cut (step 310).

Next, upper processing, right space processing, and lower processing of the third line (LINE 3) are performed in sequence (step 320).

The upper part machining, right space machining, and lower part machining in 3) will be described in detail later with reference to FIGS. 12 to 14.

When the machining of the third line (LINE 3) is completed, the drill 37 is raised vertically in the seven-axis direction and moved to the origin (step 350). Then, it is checked whether or not there is a hollow character (step 360). If there is no hollow character, the process proceeds to step 390 of the flow shown in FIG. 6(d), moves to the machine origin, and stops the machine. Signal M
In step 40o, the processing is completed by sending out the
If there is a hollow character, the process proceeds to step 370, the table 25 is moved so that the drill 37 is positioned at the starting point of the hollow character, and one character is hollowed out (step 380). Then, the process returns to step 360 and steps 360 to 380 are repeated until all hollow characters have been processed.

The above is the main part of the cutting process 70- of the raised pattern. Next, the detailed flow of each process will be explained with reference to FIGS. 7 to 15.

First, the processing of the first line (LINE1) will be explained with reference to FIG. The cutting process for the first line (LINE1) will be explained with reference to the case where the character string "01" shown in FIGS. 16(a) to 16(h) is processed.

In the processing of this first line (LINEl), first, the character is moved from the character origin 0 to the processing start point 31LI (Step 705), and from this processing start point 31u, it follows the arrow attachment line 71 as shown in FIG. 16(a). In order to cut the left part of the first character "0", 7B*LU information (7BOLU information in this example) is transferred to the cutting device 9 (step 710). As a result, the left part of the first character rOJ is the first
As shown in FIG. 6(a), processing is performed from the starting point 31u toward the ending point EILI.

It is then checked for the next character (step 715). If there is no next character, now step 7
Since the first character processed in step 10 is the last character, proceed to step 720 and, for example, as shown in FIG. 7B*RD (7BO
RD) information is transferred and processed from the start point Srd, which is the same position as the processing end point Etu of the right part of the first character "0" that has been completely processed, toward the end point Erd.

That is, in the present invention, the machining end point of one step before and the machining start point of the next step are at the same position, so that machining is performed continuously.

As a result of the check in step 715, if there is a next character, the process advances to step 725, where it is checked whether the next character is blank. If the next character is blank,
Proceeding to step 730, as shown in FIG. 16(g),
Considering the 1-pitch interval between the first character and the next character, the sum of the right part of the first character, the 1-pitch interval, and the left part of the next character is r7B*RD+1 pitch+78*LD
j is calculated, and this total processing information is transferred, thereby converting the right part of the first character, the left part of the next character opening left by one pitch, and the blank part between the two into Figure 16 (marked with the arrow in (1)). It is processed as shown by the human line 72.

If the next character is not blank in the check at step 725, the processing information r7B*RD+7R*LDJ is transferred to process the right part of the first character and the left part of the next character, and this part is Figure 16(b) and Figure 16(
Processing is performed as shown by arrowed lines 73 and 74 in C) (step 735).

Then proceed to step 740.

In step 740, a check is made to see if there are any more characters. Next, if there is no character, proceed to step 745 and process the right part of the Nth character as shown in FIG. 4(d).
or 7B*RD or 7B*R as shown in (C)
Transfer the U information and process this part.

If there is a next character, a check is made to see if the next character is blank (step 750). If the next character is blank, processing information for the right part of the Nth character and the next left part separated by one pitch is transferred, and this part is processed (step 755).

If the next character is not blank, step 73
Similarly to 5, processing information r7B*RD+7B*LDJ or r7B*RU+ for the right part of the Nth character and the left part of the next character.
78*LUJ is transferred and this part is processed as shown in FIG. Floating on the 1st line (LINEI).

Next, the contour processing of the first line (LINE1) will be explained with reference to FIG. This first line (LINEl>

1" will be explained.

Before starting the contour machining process of the first line (LINEI), as a result of the machining process of the first line (LINEI) shown in FIG. 7, the drill 37 of the cutting device 9 is as shown in FIG.
As shown in , it is located at the upper right of the rightmost character "1" of the character string "01", so this upper right point is the starting point Sp of contour processing.
From this starting point Sp, processing information 7 for processing the outline of the rightmost character "1" as shown by the arrow line 75 is obtained.
B*P is transferred, the outline of the character "1" is processed, and it ends at the upper center end point Ep of the character "1" (Stella 2 Pu 81
0).

Next, in step 830, it is checked whether or not all contour processing has been completed, and if it has not been completed, the dotted line shown in FIG. 16(f) is moved toward the contour starting point Sp of the next character "0" As shown by 76, the drill 37 is raised and moved while floating (step 840), and then the contour machining information 7
Transfer B*P and process the outline of the letter “O” in the same way (
step 850). This contour processing is repeated for all necessary characters.

FIGS. 9 to 11 respectively show the second line (LL N
This is a flowchart of the processing of the upper part, fabric space, and lower part of E 2 >, and these processing flows are all carried out along the third line (L
The processing flow for the top, right space, and bottom of INE3) is all the same, so the first step explained below
Please refer to the processing flows in FIGS. 2 to 14.

First, the third line (LINE3) with reference to FIG.
For example, processing of the upper part of a raised character string of a name, etc. will be explained. The cutting process for this third line (LINE 3) is not shown in FIGS. 17(a) to 17(j), and will be described for the case where the character string "rABCD口口" is calculated on a daily basis. Note that the mouth is blank.

In the upper part machining process of this third line (LINE3), first, the character is moved from the character origin O to the machining start point Su (step 1210), and from this machining start point SLI, as shown in FIG. 17(a).
As shown in FIG. 17<C), the arrow attachment lines 81a to 8
In order to cut the upper part to the first character rAJ according to step 1c, the NC*U information (NGAU information in this example) as shown in FIG. 1220). As a result, the upper part of the first character rAJ is processed from the starting point 3u toward the ending point Ell as shown in ('a) to (C) in FIG. 17. The end point Eu of this processing is at the upper right of the character rAJ, as shown in FIG. 17(C).

Then, it is checked whether or not all character processing has been completed (step 1230>. If not, as shown in FIG.
The drill 37 is raised and moved from the end point ELI of "" to the start point 3u of the next character rBJ to be machined (step 1240). Then, processing information NC*U (NCBU) for the upper part of the character rBJ is transferred, and the upper part of the character is processed (step 125.0). Thereafter, the process is repeated in the same manner until the upper parts of the letter "C" and rDJ are all processed.

Next, processing of the right space of the third line (LINE3) will be explained with reference to FIG.

First, it is checked whether there is space in the right portion (step 1310). If there is a space on the right side,
The number of spaces in the right part is calculated, space processing information for this number is transferred, and the spaces in the right part are processed, for example, as shown by the arrowed line 82 in FIG. 17(d') (step 1320). The number of repetitions of the horizontal cutting process indicated by the arrow line 82 is an odd number,
The final point of this odd number of horizontal cutting processes reaches the processing start point Sd of the character rDJ, where the lower part is to be processed next (step 1330).

Further, as a result of the check in step 1310, if there is no space on the right side, the process is directly moved to the starting point Sd at the bottom of the character to be performed next (step 1340).

The lower part processing of the third line (LINE 3) will be explained with reference to FIG. 14. At the end of the processing of the right space shown in Fig. 13, the process ended at the lower right point of the character rDJ, that is, the starting point 3d of the lower part processing, as shown in Fig. 17(d), but from the starting point Sd of this lower part processing. As shown by the arrow mark line 83 in FIG. 17(e), the information NC*D (NCDD) for processing the lower part of the first character rDJ is transferred, and the lower part of the letter "D" is processed according to this information. It reaches the lower left end point Ed of rDJ (step 1410).

Then, it is checked whether all character processing has been completed (step 1420). If it is not completed, as shown in Figure 17(e), the fully processed character rD
The drill 37 is raised and moved from the end point Ed of J to the start point Sd of the character "C" to be machined next (step 1430). Then, processing information NC*D (NCCD) for the lower part of the character "C" is transferred, and the lower part of the character is processed (step 1440). Thereafter, the process is repeated in the same manner until the lower parts of the characters rBJ and rAJ are all processed. Incidentally, FIG. 17 (D) shows that the lower part of the letter "AJ" is processed as indicated by the arrow bonnet -84.

In this way, when the machining of the lower part of the letter FA'' is completed, the drill 37 located on the absent end point Ed of the letter rA'' is raised and floated while moving to the letter origin O as shown in FIG. 17(g). (Step 3 in Figure 6 (C)
50), then hollowing is performed as shown in steps 360-380 of FIG. 6(C) and twisted. In this case, =28- The transfer process of hollow data and the hollow processing process are the 15th
This is shown as step 1510 in the figure.

Further, in FIG. 17(i), the hollowing process end point Eac of the character rAJD is moved from the hollowing start point 3a of the next character rBJ.

The jump movement route of the drill 37 is shown by a thick dotted line, and in FIG. Starting point SaC for hollowing out the letters rDJ
The routes to each are indicated by thick dotted lines.

Although the above embodiment describes the case where a raised character string or the like is formed on a card such as an IC card, the method for forming a raised pattern of the present invention is not limited to application to cards.

Furthermore, although the above embodiment describes the case of character strings arranged in the horizontal direction, the present invention is not limited to this.
The same applies to character strings arranged in the vertical direction.

[Effects of the Invention] As explained above, according to the present invention, a raised pattern is continuously formed according to processing position data consisting of relative coordinate data with respect to a predetermined origin related to the raised pattern. Even when the raised pattern consists of a plurality of consecutive character strings, the spaces between each character can be smoothly and continuously formed efficiently.
