Abstract

PURPOSE:To form a relief pattern efficiently by a method wherein, a symbol processing is divided into a rough shape forming processing, an outline processing, and a hollow processing, this divided processing information is provided for every symbol, and the processing is continuously conducted in the order of a rough shape forming processing, an outline processing, and a hollow processing. CONSTITUTION:For example, in the case of processing a character 8, a point on the upper left-hand of the character 8 close to a character origin O is determined as a processing start point Slu, and therefrom 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. Next, from a center point downward of the character 8 determined as a start point, the right side is cut upward. The processing is ended at an end point on the upper right-hand of the character 8. After that, from a start point Sp on the upper right-hand of the character 8 the outline of the character 8 is processed as shown by a heavy line 55 up to an upper left-hand end point Ep. Next, from a start point Sc the drill is skipped to an isolated hollow part of the character 8 as shown by a heavy dot line 56, the hollow part is processed as shown by a heavy line 57, and the processing is ended at an end point Ec on the right-hand part of the lower hollow part. In this manner, the character is continuously cut by various methods as if being drawn with a single stroke of the brush.

Description

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

(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 sandwiching and pressing the card from both sides with male and female molds that have the same character pattern as the raised characters, thereby raising the card itself. The letters were deformed so that they protruded to one side, forming raised letters.

However, with this method, it is necessary to form a male mold or a female mold corresponding to each raised character, and the raised characters are formed by deforming the card itself so that it partially protrudes. Due to the expansion of functions, especially the expansion of the functions of IC cards, card-type calculators are equipped with a numeric keypad or liquid crystal display on the surface of the card to input and display information on the IC card itself. It is no longer possible to use male and female dies to form raised letters without deforming the card itself, and currently C゛ is 1, which forms raised letters on the surface of the card.
However, in order to form raised characters on the surface of the card, an embossed character forming pedestal made of a plastic material such as vinyl chloride that forms the card and a material with physical characteristics such as hardened polymer, etc., is used. A method has been considered in which the laminated pedestal for forming raised characters 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 thereof 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 Problems) In order to achieve the above object, the method for forming a raised pattern of the present invention is a method of forming a raised pattern by cutting. The processing of each symbol to be processed is divided into outline forming processing, contour processing, and hollow processing, and this divided processing information is provided for each symbol, and the processing is performed continuously in the order of outline forming processing, contour processing, and hollow processing. The gist is to implement it.

(Function) In the method for forming a raised pattern of the present invention, the processing of each symbol is divided into outline forming processing, contour processing, and hollow processing, which are provided for each symbol, and the processing of outline forming, contour processing, and hollow processing is performed in the order of Continuous processing.

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

The cutting device 9 is controlled according to the stored control program for forming a raised pattern and the position information, control information, etc. stored in the second memory 5, thereby efficiently forming a raised pattern consisting of a plurality of consecutive character strings. And it is continuously formed by cutting.

Furthermore, the cutting device 9 includes a cutting position control section 90 and ~
The cutting position control section 90 controls the cutting section 91 based on the position information and control information for cutting the raised pattern supplied from the calculation section 1 via the I10 interface 7. A raised pattern is formed by cutting the base material for the raised pattern.

FIGS. 2(a) and 2(b) are a front view and a side view showing the structure of the cutting device 9, respectively. The cutting device 9 shown in the figure includes a table 25 on which a card base material such as an IC card to be cut is placed, and this table 2.
A cutting drill 37 is provided above the cutter 5. The drill 37 is fixed to the tip of the spindle 31, and the spindle 31 is driven to rotate by a motor 35 through a rotation repeater 33.

The spindle 31 and the rotary repeater 33 are attached to a moving table 30, and this moving table 30 is movable in the vertical X-axis direction, that is, in the direction in which the drill 37 vertically approaches and leaves the table 25. It is attached to the main body 27 of the cutting device 9, and when the moving table 30 moves in the F direction, the drill 37 comes into contact with the card base material etc. on the table 25 and can cut the card base material etc. When the moving table 30 moves upward, the drill 37 separates from the card base material etc. on the table 25.

Further, the table 25 is movable in the X-axis direction, which is horizontal to the device main body 27, by a motor (not shown), and further movable in the Y-axis direction, which is perpendicular to the X-axis direction and horizontal. It is mounted on a stand 29, which allows the table 25 to move in the horizontal Y-axis and in the Y-axis direction. In this case, the motor 35
By moving the table 25 along the Y-axis and the Y-axis while the rotating drill 37 is in contact with the card base material, etc., a predetermined raised pattern is formed on the card base material, etc. This is possible.

In the cutting device 9 shown in FIG. 2, the cutting position control section 90, input device 13, and display device 17 are attached at approximately the same height as the table 25, thereby improving operability.

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, "011" is formed with the raised characters 12 QT.

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 10, similarly, 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".
A card base material 10 as shown in FIG. 3 to be cut is placed on the daple 25. Next, when the power is turned on to the raised pattern forming device shown in FIG.
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 01 of the raised character string to be cut is, for example, shown in FIG.
The upper left character origin O of the character string consisting of "01" shown in ai
The table 25 is controlled to be moved so that the drill 37 of the cutting device 9 is positioned above the table 25 (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 0 of the raised character string "01" to be cut, the spindle 31 is lowered via the moving table 30, thereby cutting the raised character string "01" at the tip of the drill 37. It is brought into contact or pressure contact with the surface of the raised character forming pedestal 108 or the like on the card base material 10 on which rows are 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 (LINEI>) 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, cutting of the contour of the first line (LINEI) is performed as shown in FIG.

Processing of the 1st line < LINEI) and the processing of the 1st line (,
When the contour machining of L I N E 1 ) is completed, the next step is hollow machining, so first, the drill 37 is raised perpendicularly to the Z-axis direction and moved to the origin (step 170). It is then checked to see if there are any hollow characters (step 180).

If there is no hollow character, the process proceeds to step 210 in the flow of FIG. 6(b), but if there is a hollow character, the process proceeds to step 190, where the drill 37 is positioned at the processing start point of the hollow character. The table 25 is moved as shown in FIG. The repetitive operation of hollow cutting is shown in Fig. 16 < h, , >, but in the case of a character string such as "o123456.J", there is a jump from the processing end point of letter O to the processing start point of character 6. It is carried out by moving as if

If there are no hollow characters or if all the hollow characters have been hollowed out, step 2 in Figure 6(b)

I N E 2. ) will be described later with reference to FIGS. 9 to 11.

When the machining of the second line (LINE2>) is completed, the drill 37 is raised vertically in the Z-axis direction and moved to the machine origin (step 26o).

It then checks to see if there are any hollow characters (step 270). If there are no hollow characters, please refer to Figure 6 (
Proceed to step 300 of the flow of c'), but if there is a hollow character, proceed to step 280, move the table 25 so that the drill 37 is positioned at the starting point of the hollow character, and hollow out one character. Perform processing (step 290)
. Then, the process returns to step 270 and steps 270 to 290 are repeated until all the hollow characters have been processed.

If there is no center or cut-out character, or if all the hollow characters have been cut out, the process proceeds to step 300 in FIG. In order to perform cutting on the third line (LINE3) of the three-line character string formed in , move to the character origin ◯ of the third line < LINE 3 ).

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).

When the machining of the third line (LINE 3) is completed, the drill 37 is raised vertically in the Z-axis direction and moved to the origin (step 350). It is then checked to see if there are any hollow characters (step 360). If there is no hollow character, proceed to step 390 in the flow of Fig. 6 (di), move to the machine home position, and send the machine stop signal 8 M
is sent out to end the processing (step 400),
If there is a hollow character, proceed to step 370, move the 7-pull 25 so that the drill 37 is located at the starting point of the hollow character, and perform hollow processing for one character (step 380). ). Then, the process returns to step 360 and all hollow characters are processed.Steps 360 to 38
Repeat 0.

The above is the main flow of the cutting process 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 (LINE1), first, the character is moved from the character origin O to the processing start point Slu (step 705), and from this processing start point S1u, it follows the arrow attachment line 71 as shown in FIG. 16(a). In order to cut the left part of the first character "O", 7B* and U information (in this example, 7BOL U information) is transferred to the cutting device 9 (Step 710). As a result, the left part of the first character "○" is processed from the starting point 31u to the ending point E1u as shown in FIG. 16 <a>.

It is then checked whether there is another character (step 71'5'). If there is no next character, the first character processed in step 71"O is the last character, so proceed to step 720, for example in FIG.
), the right part of the first character processed in step 710 is processed <7B*RD (, 7B ORD ) information is transferred, and the processing end point Elu of the right part of the first character "O" processed just now is transferred. Processing is performed from the starting point 3rd, which is the same position as , toward the ending 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. 1'6 (g), taking into account the interval of one pitch between the first character and the next character, Then, calculate the sum of the left part of the next character r 7 B * R'D"+ 1 pitch + 7B * LD", transfer this total processing information, and calculate the right part of the first character, 1 pitch gap. The left part of the opening of the next character and the blank part between the two are number 16.
Processing is performed as shown by the arrowed line 72 in the figure (g>).

If the next character is not blank in the check at step 725, the processing information r7B*RD+7R*LDJ is transferred so as not 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<
Process as shown by arrow lines 73 and 74 of 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 by 7B*RD or 7 as shown in FIG. 4(d) or (C,).
B *Transfer RU 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, the processing information for the next left part is transferred and processed by one pitch from the right part of the Nth character in the same way as in step 730 (step 755). .

If the next character is not blank, step 73
Similarly to 5, processing information for the right part of the Nth character and the left part of the next character r7B*RD+, 7B*LDJ or r7B
Transfer *RU+7B*LUJ and process this part as shown in Fig. 16(e) (Step 7
60).

Thereafter, the same processing is repeated until the end of the character example "01...", and the raised/raised character string of the first line (LINE1) is cut.

Next, the contour processing of the first line (LINE1) will be explained with reference to FIG. This first line (, LINE
) will be described with reference to the case where the character string "ol" shown in FIG. 16(f) is processed.

Before starting the contour processing of the first line (LINEI), as a result of the processing 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 ・Since it is located at the upper right of the rightmost character "1" of the character string "ol", this upper right point is the starting point S of contour processing.
p, and processing information 7B*P for processing the outline of the rightmost character "1" is transferred from this starting point Sp as shown by the thick line 75 on the arrow side, and the outline of the character "1" is processed, resulting in the character "1". Step 81
0).

Next, in step 830, it is checked whether all the contour processing has been completed, and if not, the dotted line shown in FIG. As shown by 76, the drill 37 is raised and moved while floating (step 840), and the contour machining information 7 is obtained from each of them.
B*P is transferred and the outline of the character rOJ is similarly processed (step 850). This contour processing is repeated for all necessary characters.

Figures 9 to 11 show the second line (LINE2).
This is a flowchart for the processing of the upper part, right space, and lower part of
The third line (LINE3) shown in FIGS.
) are all the same as the processing flow of the upper part, right space, and lower part, so please refer to the processing flow of FIGS. 12 to 14 described below.

First, the third line (L I NF2
), for example, processing of the upper part of a raised character string of a name, etc. will be explained. The cutting processing of this third line (LINE 3) will be explained in the case where the character string "rABCD 口口" shown in FIGS. .

In the upper part processing of this third line (LINE 3), first, the character is moved from the character origin O to the processing start point Su in step 1210>, and from this processing start point Su as shown in FIGS. 17(a) to 17(C). Arrow attendant lines 81a to 81
NC*U information (in this example, NCAU information) as shown in FIG. Step t220>.As a result, the upper part of the first character rAJ is processed from the starting point 3u toward the end point Eu as shown in (a) to (C) in FIG. 17.The end point Eu of this processing is As shown in Figure 17 (C), it is at the upper right of the letter "A".

Then, it is checked whether all character processing has been completed (step 1230). If it is not finished, as shown in Fig. 17 (C), the character rA just processed
The drill 37 is raised from the end point EIJ of J to the start point Su of the character IB to be machined next and moves while floating at τ (Step Co. 240). Then, processing information NC*U (NCBU) for the upper part of the character "B" is transferred, and the upper part of the character is processed (step 1250). Thereafter, the process is repeated in the same manner until the upper parts of the letters "C" and "D" 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 arrow attachment 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, and the final point of the odd number of horizontal cutting processes is the next time the lower part machining cannot be performed. The machining start point 3d is now reached (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, it ended at the lower right point of the sea urchin character rDJ shown in Fig. 17(d), that is, the starting point Sd of the lower part processing, but the starting point of this lower part processing The information NC*D (NCDD) for processing the lower part of the first character rDJ is transferred from Sd to the arrow line 83 in FIG. 17(e), and the lower part of the letter "D" is processed according to this information. , reaches the lower left end point Ed of the character rDJ (step 1410).

Then, it is checked whether all character processing has been completed (step 1420). If it is not finished, as shown in Fig. 17(e), the character rD just processed is
The drill 37 is raised and moved from the end point Ed of J to the start point 5d of the character "C" to be machined next (step 1430). Then, the processing information NC*D (NGCD> for the lower part of the character "C" is transferred, and the lower part of the character is processed (step 1440). Thereafter, the lower parts of the characters "B" and "A" are processed in the same manner. 17(f) shows that the lower part of the letter rAJ is processed as indicated by the arrowed line 84.

In this way, when the lower part of the letter "A" has been processed, the drill 37 located on the end point Ed where the letter rAJ is absent is raised and floated until it reaches the origin of the letter as shown in Fig. 17<g). 0 (step 350 in FIG. 6(C)), and then hollowing is performed as shown in steps 360 to 380 in FIG. 6(C). In this case, the hollow data transfer process and hollow processing process are shown as step 1510 in FIG.

Moreover, in FIG. 17(i), the hollowing process ends point EaC of the character rAJ to 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 FIG. 17(j) shows the route from the hollowing end point EaCi above the letter rBJ to the hollowing start point SaC below and from the letter rBJ. 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 a 1G 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] -2n- As explained above, according to the present invention, the processing of each symbol is divided into outline forming processing, contour processing, and hollow processing, and each symbol is provided for each symbol. Since processing is performed continuously in the order of machining and hollowing, each symbol can be processed smoothly and continuously in an efficient manner.
