(First embodiment)
(Schematic configuration of laser processing equipment)
A schematic configuration of the laser processing apparatus 1 according to the present embodiment will be described with reference to FIG. A laser processing apparatus 1 according to the present embodiment includes a PC (Personal Computer) 7, a laser processing unit 2, a laser controller 5, and the like. The laser processing unit 2 includes a laser head unit 3 and a power supply unit 6. Based on the information transmitted from the laser controller 5, the laser processing unit 2 irradiates the processing surface WA of the processing target object W with the laser light L by two-dimensional scanning and marks characters, symbols, figures, and the like. Perform laser processing. In the following description, laser processing may be described as printing.

  The PC 7 is realized by, for example, a notebook PC, and includes an LCD (Liquid Crystal Display) 77, a keyboard 76, a mouse 78, and the like. The PC 7 receives a processing command from a user, creates print data, and outputs the print data to the laser controller 5. Here, the print data corresponds to the XY coordinate data indicating the shape of the processing pattern drawn by the laser beam L in the laser processing, and the processing condition data indicating the processing conditions which are the laser processing conditions associated with the XY coordinate data. Data. The laser controller 5 is realized by a computer or the like, and is connected to the laser processing unit 2 and the PC 7 so as to be capable of bidirectional communication. The laser controller 5 controls the laser processing unit 2 based on the print data output from the PC 7. In the following description, the direction shown in FIG.

  The laser head unit 3 includes a main body base 11, a laser beam emitting unit 12 that emits a laser beam L, an optical shutter unit 13, an optical damper (not shown), a half mirror (not shown), a guide beam unit 15, a reflection mirror 17, The optical sensor 20, the galvano scanner 18, the fθ lens 19, and the like are included, and are covered with a substantially rectangular parallelepiped housing cover (not shown).

  The laser beam emitting unit 12 includes a laser oscillator 21 and a beam expander 22. The laser beam emitting section 12 is attached to the main body base 11, and excitation laser light that is excitation light emitted from the excitation laser beam emitting section 40 (described later) is incident through the optical fiber F. The laser oscillator 21 includes, for example, a YAG laser (not shown) and a passive Q switch. The laser oscillator 21 emits pulsed laser light L for processing the processing surface WA of the processing target object W in accordance with the excitation laser light incident through the optical fiber F. The beam expander 22 is provided coaxially with the laser oscillator 21 and adjusts the beam diameter of the laser light L. The direction in which the laser oscillator 21 emits the laser light L is the forward direction, and the direction perpendicular to the vertical direction and the front-rear direction of the laser head unit 3 is the horizontal direction of the laser head unit 3.

  The optical shutter unit 13 includes a shutter motor 26 and a flat shutter 27. The shutter 27 is attached to the motor shaft of the shutter motor 26 and rotates coaxially. When the shutter 27 is rotated to a position that blocks the optical path of the laser light L emitted from the beam expander 22, the shutter 27 reflects the laser light L to the optical damper. The optical damper absorbs the laser light L reflected by the shutter 27. On the other hand, when the shutter 27 is rotated to a position that does not block the optical path of the laser light L emitted from the beam expander 22, the laser light L emitted from the beam expander 22 is directed to the front side of the optical shutter unit 13. Incident to the arranged half mirror. The half mirror transmits almost all of the laser beam L incident from the rear side and reflects a part thereof to the reflection mirror 17. The laser light L that has passed through the half mirror is incident on the galvano scanner 18. The reflection mirror 17 reflects the incident laser light L to the optical sensor 20. The optical sensor 20 outputs a signal corresponding to the emission intensity of the incident laser light L to the laser controller 5.

  The guide light unit 15 includes a guide light laser 28 (FIG. 2) and a lens group (not shown). The guide light laser 28 is, for example, a red semiconductor laser that emits visible laser light. A lens group (not shown) converges visible laser light into parallel light. The guide light unit 15 is disposed on the right side of the half mirror. The half mirror reflects guide light, which is visible laser light emitted from the guide light unit 15, toward the galvano scanner 18. Here, the optical path of the guide light reflected by the half mirror coincides with the optical path of the laser light L transmitted through the half mirror. The guide light is used for alignment of the workpiece W during laser processing.

  The galvano scanner 18 is attached to the upper side of a through hole (not shown) formed in the front end portion of the main body base 11. The galvano scanner 18 includes a galvano X-axis motor 31, a galvano Y-axis motor 32, a main body 33, and the like. Each of the galvano X-axis motor 31 and the galvano Y-axis motor 32 has a scanning mirror attached to the motor shaft and the tip of the motor shaft. The galvano X-axis motor 31 and the galvano Y-axis motor 32 are attached to the main body 33 such that the motor axes are orthogonal to each other and the scanning mirrors face each other. As each motor 31 and 32 rotates, each scanning mirror rotates. Thereby, the laser beam L and the guide beam are two-dimensionally scanned. Here, the scanning directions are an X direction from the front to the rear and a Y direction from the right to the left in the direction of the laser head unit 3.

  The fθ lens 19 condenses the laser light L and the guide light that are two-dimensionally scanned by the galvano scanner 18 on the processing surface WA of the processing target W disposed below.

  The power supply unit 6 includes an excitation laser beam emitting unit 40, an excitation laser driver 51, a power supply unit 52, and the like. The power supply unit 52 is connected to a commercial power supply via a power cord (not shown). The power supply unit 52 converts the AC power supplied to DC power and supplies the power to each part of the laser processing unit 2. The excitation laser driver 51 drives the excitation laser light emitting unit 40 in accordance with a command from the laser controller 5. The excitation laser beam emitting section 40 is optically connected to the laser oscillator 21 via the optical fiber F. The excitation laser beam emitting unit 40 includes a semiconductor laser, and emits excitation laser beam having a power corresponding to the current value of the drive current supplied from the excitation laser driver 51 into the optical fiber F.

(Electric configuration of laser processing equipment)
Next, the electrical configuration of the laser processing apparatus 1 will be described with reference to FIG. The PC 7 includes a control unit 70, a control circuit 74, and the like in addition to the configuration shown in FIG. The control unit 70 includes a CPU 71, a RAM 72, a ROM 73, an HDD (Hard Disk Drive) 75, and the like. Application software for laser processing is installed in the PC 7 in advance. The ROM 73 stores firmware and the like. The RAM 72 is used as a main storage device for the CPU 71 to execute various processes. The HDD 75 stores a processing program, character parameter information, and the like.
The character parameter information is parameter information for each font. For example, in the case of a stroke font, it is information such as coordinates of the center point of the character and parameters of an expression representing a line connecting the points. In the case of an outline font, it is information such as coordinates of points constituting the outline of a character and parameters of an expression representing a line connecting the points. The HDD 75 stores a program for setting reception processing and display processing, which will be described later, used in cooperation with application software for laser processing, and a parameter set table 200 (FIG. 3). The CPU 71, RAM 72, and ROM 73 are connected to each other by a bus line (not shown). Further, the CPU 71 and the HDD 75 are connected via an input / output interface (not shown). Further, the PC 7 has a transmission unit (not shown) that transmits print data to the laser controller 5.

  The control circuit 74 is electrically connected to the LCD 77, the keyboard 76, the mouse 78, etc., converts the operation received by the keyboard 76 and the mouse 78 into a signal, and outputs the signal to the CPU 71. In addition, a display screen corresponding to a command from the CPU 71 is displayed on the LCD 77.

  The laser controller 5 is realized by, for example, a computer and includes a CPU 41, a RAM 42, a ROM 43, and the like. The CPU 41 executes various programs stored in the ROM 43 to control a galvano controller 56, a guide light laser driver 58, an excitation laser driver 51, and the like which will be described later. The RAM 42 is used as a main storage device for the CPU 41 to execute various processes. The CPU 41, the RAM 42, and the ROM 43 are connected to each other by a bus line (not shown). Based on the print data output from the PC 7, the laser controller 5 creates drive information including drive information including the drive angle and rotational speed of the galvano scanner 18 and drive current value of the excitation laser driver 51, and laser processing. A printing process for controlling the unit 2 is executed.

  The laser head unit 3 includes a galvano controller 56, a galvano driver 36, a guide light laser driver 58, and the like in addition to the configuration shown in FIG. The galvano controller 56 outputs, for example, a control signal such as a drive current value and ON / OFF to the galvano driver 36 based on the drive information input from the laser controller 5. The galvano driver 36 supplies a drive current corresponding to the control signal input from the galvano controller 56 to the galvano X-axis motor 31 and the galvano Y-axis motor 32.

  Next, the parameter set table 200 will be described with reference to FIG. The CPU 71 receives setting of machining conditions in order to create machining condition data. Here, specifically, the processing conditions include seven conditions shown as items of the parameter set table 200: laser output, number of times of printing, printing speed, jump speed, laser ON delay, laser OFF delay, and jump delay. is there. The laser output is an output value of the laser light L, and the unit is a percentage.

  Here, the processing pattern will be described with reference to FIG. The processing pattern is a pattern printed by one printing process, and includes one or more objects Obj. Here, the object Obj is a series of characters, symbols, figures, and the like. FIG. 7 shows character objects Obj1 to Obj4 having a series of characters as an example of the object Obj. In addition, there is a graphic object Obj such as a QR code (registered trademark).

  The number of times of printing is the number of times one object Obj is printed in one printing process. For example, when the number of times of printing is two, after the pattern is formed by the first printing, the second printing is performed so as to trace the formed pattern. The printing speed is a speed at which the irradiation position of the laser light L on the processing surface WA moves in accordance with the scanning of the galvano scanner 18.

  The jump speed is a speed at which the focal position of the laser light L on the processing surface WA moves from the end point of one line segment to the start point of the next line segment when the object Obj is composed of a plurality of line segments. . When the laser processing apparatus 1 prints one object Obj composed of a plurality of line segments, specifically, each of the plurality of line segments constituting the object Obj is sequentially printed. When the laser processing apparatus 1 scans the laser light L and prints one line segment constituting the object Obj, the laser processing apparatus 1 turns off the output of the laser light L once, and the irradiation position of the laser light L on the processing target W The galvano scanner 18 is operated until is the start position of the next line segment. Next, the laser processing apparatus 1 scans the line segment by operating the excitation laser driver 51 to turn on the laser output. Here, OFF is a stop state in which the laser light L is not emitted from the laser oscillator 21, and ON is an output state in which the laser light L is emitted from the laser oscillator 21. The laser processing apparatus 1 repeats the above operation and prints one object Obj except when the object Obj is composed of one line segment. The laser ON delay is a period from when the focus position of the laser beam L is moved by the galvano scanner 18 to the start point of the first printed line segment of the object Obj to be printed first in the printing process, until scanning is started. This is a waiting time until the laser output is turned on. The laser OFF delay is a waiting time until the laser output is turned off after the focal position of the laser beam L reaches the end point of the last printed segment of the object Obj printed in the printing process. is there. The jump delay is a time for waiting for scanning after printing of one line is completed and the galvano scanner 18 moves the focal position of the laser beam L to the start position of the line to be printed next. Note that the unit of the jump speed and the jump speed is mm / sec, and the unit of the laser ON delay, the laser OFF delay, and the jump delay is μs.

  It is complicated for the user to set these conditions one by one. Therefore, the laser processing apparatus 1 stores a plurality of parameter sets in which the values of the respective conditions are set in advance as data of the parameter set table 200. The user can easily set the machining conditions by selecting one of the parameter sets stored in the parameter set table 200. Here, it is assumed that the parameter set table 200 stores three parameter sets A to B. The parameter sets A to B are different from each other in at least one of the plurality of conditions. For example, different parameter sets are applied to the workpiece W when the workpiece W is made of different materials of resin and metal.

  Next, the layer table 400 will be described with reference to FIG. The laser processing apparatus 1 uses a GUI (Graphical User Interface) when receiving processing conditions. Specifically, the laser processing apparatus 1 displays an acceptance screen 90 shown in FIG. 6 on the LCD 77 and accepts an operation by the user. The layer table 400 is used when displaying the object Obj on the reception screen 90. The layer table 400 is data in which a layer ID, a display color, a parameter set, and an object ID are set as one set. Among these, fixed values are stored in advance for the layer ID and the display color. On the other hand, the parameter set and the object ID show a state in which values are input in FIG. 4A, but in the initial state stored in the HDD 75, the values are empty. Note that the value of the parameter set is any one of A to C, and the value of the object ID is a natural number. The layer table 400 has three rows for storing values, which is the same as the number of parameter sets stored in the parameter set table 200. Here, the layer is an attribute for defining a display mode in a layout area 92 (described later) of the reception screen 90, and objects Obj to which the same layer is applied are displayed in the same display mode. Here, layer IDs 1 to 3 are assigned to the three layers used. Here, the display mode is specifically a display color. The display colors corresponding to the layer IDs 1 to 3 are black, blue, and red, respectively.

  Next, a setting reception process that is executed in order to receive the setting of the machining conditions will be described. Here, a case where the processing pattern includes four objects Obj1 to Obj4 shown in FIG. Further, it is assumed that the parameter set applied to the objects Obj1 and Obj3 is the parameter set A, and the parameter set applied to the objects Obj2 and Obj4 is the parameter set B. The objects Obj1 to Obj4 are character objects Obj whose contents are character strings “ABCD”, “EFGH”, “1234”, and “5678”, respectively.

  When the power of the laser processing apparatus 1 is turned on and an application for processing is started on the PC 7, the CPU 71 starts a setting reception process shown in FIG. When the CPU 71 starts the setting acceptance process, first, the acceptance screen 90 (FIG. 6) is displayed on the LCD 77 (S1). Here, the reception screen 90 will be described with reference to FIG. Note that the direction shown in FIG. 6 is used to describe the reception screen 90. The reception screen 90 includes a menu button display area 91, a layout area 92, a processing setting screen 93, an input end button 94, and the like. In the menu button display area 91, for example, a file button 91a, an insert button 91b, a setting button 91c, and the like are displayed. The layout area 92 is an area for receiving the arrangement of the object Obj in the processing area. The layout area 92 represents a machining area in the workpiece W, and the arrangement position of the input object Obj in the layout area 92 is a machining position where the laser beam L is irradiated in the machining area. The right direction of the layout area 92 is the X direction of the machining area, and the upward direction is the Y direction of the machining area. On the reception screen 90, a pointer 95 corresponding to the position of the mouse 78 is displayed. On the processing setting screen 93, an input text box 96, a parameter set list button 97, and an OK button 98 are displayed. The process setting screen 93 is displayed in an invalid state where no input is accepted in step S1.

  Returning to FIG. 5, next, the CPU 71 determines whether or not an object input operation has been accepted (S3). For example, when the insert button 91b is selected, the CPU 71 determines that an object input operation has been accepted. Note that “selection” here refers to an operation in which the mouse 78 is clicked in a state where the pointer 95 is positioned within the display range of the insertion button 91b, for example, and is the same in the following description. When inputting an object, the user selects the insert button 91b, and clicks the mouse 78 with the pointer 95 placed at a desired position in the layout area 92 where the object Obj is to be placed. If it is determined that the object input operation is not accepted (S3: NO), the CPU 71 repeatedly executes step S3 until it is determined YES. If it is determined that an object input operation has been accepted (S3: YES), the CPU 71 accepts an input operation on the processing setting screen 93 (FIG. 6) in response to the position in the layout area 92 being selected by the pointer 95. Switching to the valid state, the setting of the contents of object Obj and the processing conditions by the user is accepted (S5). The user inputs a desired character string in the input text box 96 that has become valid, selects one of the parameter sets A to C using the parameter set list button 97, and selects the OK button 98.

  Next, the CPU 71 determines whether or not the OK button 98 has been selected. If it is determined that the OK button 98 has not been selected (S7: NO), the process returns to step S7, and step S7 is repeatedly executed until it is determined YES. If it is determined that the OK button 98 has been selected (S7: YES), the layer table 400 is referred to, and it is determined whether or not the same parameter set as the parameter set input to the parameter set list button 97 is present in the layer table 400. (S11). For example, when A is input to the parameter set list button 97, it is determined whether or not A is in the parameter set column of the layer table 400. It should be noted that in the first step S11 after the setting acceptance process is started, NO is determined because there is no data in the parameter set column of the layer table 400. If it is determined that the same parameter set does not exist in the layer table 400 (S11: NO), the CPU 71 inputs the parameter set and object ID values in the layer table 400 into the parameter set column of the empty row to the parameter set list button 97. Store the value obtained. Also, the value stored in the object ID column is stored as the value obtained by incrementing the maximum value by 1 in the object ID column of the row storing the parameter set (S15). When there is no data in the layer table 400, the object ID is 1. FIG. 8A shows the layer table 400 after step S15, which is executed first after the setting acceptance process is started, is executed. The parameter set and object ID values in the first row of the layer table 400 are A and 1, respectively.

  On the other hand, when determining that the same parameter set is the value of the layer table 400 (S11: YES), the CPU 71 sets the object ID column in the same row as the same parameter set to the values stored in the object ID column. The value obtained by incrementing the maximum value by 1 is stored (S13). Next, the CPU 71 updates the display of the layout area 92 according to the layer table 400 (S17). As a result, the same layer is applied to the object Obj having the same parameter set, so that the same display color is displayed in the layout area 92. Thereby, when the user inputs a plurality of objects Obj, the object Obj having the same processing condition can be easily determined.

  Next, the CPU 71 determines whether or not the input is completed (S19). When the input end button 94 (FIG. 6) is selected, the CPU 71 determines that the input is ended. If it is determined that the input has been completed (S19: YES), the setting acceptance process is terminated. On the other hand, when the CPU 71 determines that the input is not finished (S19: NO), the CPU 71 returns to step S3. Note that the CPU 71 creates print data based on the layer table 400 when the setting reception process is completed.

  Here, description is added about the setting reception process. FIG. 4B shows the layer table 400 after the second object Obj2 is input. The parameter set applied to the object Obj2 is the parameter set B. Since the parameter set is different from the object Obj1, B is stored in the parameter set and 2 is stored in the object ID as the values in the second row of the layer table 400. FIG. 8C shows the layer table 400 after the four objects Obj1 to Obj4 are input. Since the parameter set applied to the object Obj3 is the same parameter set A as that of the object Obj1, 1 and 3 are stored in the object ID column whose parameter set value is A. Since the parameter set applied to the object Obj4 is the same parameter set B as that of the object Obj2, 2 and 4 are stored in the object ID column whose parameter set value is B.

  FIG. 7 shows the layout area 92 after the four objects Obj1 to Obj4 are input. The objects Obj1 and Obj3 have a layer ID of 1 (see FIG. 4C), and since the display color corresponding to the layer ID1 is black, they are displayed in black. On the other hand, the objects Obj2 and Obj4 have a layer ID of 2 (see FIG. 4C) and are displayed in blue because the display color corresponding to the layer ID2 is blue. In FIG. 7, the blue display is represented by hatched hatching. In this way, the objects Obj1 and Obj3 to which the same parameter set is applied are displayed in the same display color, and are displayed in a display color different from the objects Obj2 and Obj4 to which different parameter sets are applied. Thereby, even when a plurality of objects Obj are displayed, the user can easily determine the objects Obj having the same processing conditions.

Here, the laser processing apparatus 1 is an example of a laser processing apparatus, the laser beam emitting unit 12 is an example of a laser beam emitting unit, the galvano scanner 18 is an example of a scanning unit, and the CPU 71 is an example of a control unit. .
Step S5 is an example of a reception process, a reception step, a processing condition reception process, and a processing condition reception step. Step S17 is an example of a display process and a display step. The object Obj is an example of a processing pattern. Further, the object Obj that is the same parameter set is an example of a machining pattern in which specific conditions among the plurality of machining conditions are the same, and the object Obj that is a different parameter set is specified among the plurality of machining conditions. This is an example of processing patterns with different conditions. Further, the printing speed in the parameter set table 200 is an example of a scanning speed, the number of times of printing is an example of the number of times of scanning, and the laser output is an example of output intensity. The display in the same display color is an example of a display mode common to each other.

As mentioned above, according to 1st Embodiment demonstrated, there exist the following effects.
In the setting reception process, the CPU 71 applies the same layer ID to the object Obj having the same parameter set, that is, the same processing conditions, and applies different layer IDs to the object Obj having a different parameter set. As a result, the objects Obj to which the same parameter set is applied are displayed in the layout area 92 in the same display color and in a display color different from that of the object Obj to which a different parameter set is applied. Thereby, in the display of the layout area 92, the user can easily determine the object Obj having the same processing condition when the processing pattern includes a plurality of objects Obj.

(Second Embodiment)
Next, the setting reception process according to the second embodiment will be described. In the second embodiment, a description will be given of a configuration that accepts different parameter set settings for the outline portion and the filled portion for a character object Obj whose font is an outline font. The filled portion is a region surrounded by a contour line. When the object Obj is an outline font, the laser processing apparatus 1 executes a division process for dividing the object Obj into a contour line pattern and a filled portion pattern, and performs each printing separately. The same reference numerals are given to the same processing steps as the setting reception processing according to the first embodiment, and detailed description will be omitted as appropriate. In the second embodiment, the value of the object ID in the layer table 400 is a natural number or an alphabet added to the end of the natural number. For example, in order to shorten the processing time for the filled portion, for example, the scanning speed may be increased, and for the contour line, for example, the laser intensity may be increased to increase the processing depth. Thereby, it can be set as the process by which the outline was emphasized.

  When the power of the laser processing apparatus 1 is turned on and an application for processing is started on the PC 7, the CPU 71 starts setting acceptance processing shown in FIGS. When the CPU 71 starts the setting reception process, first, a reception screen (not shown) is displayed on the LCD 77 (S1). The reception screen displayed in the second embodiment is different from the reception screen 90 (FIG. 6) displayed in the first embodiment and the processing setting screen 93. FIG. 11 illustrates the processing setting screen 100 displayed in the second embodiment. The processing setting screen 100 has different display contents depending on the type of the object Obj. FIG. 11 shows the processing setting screen 100 displayed when the object Obj is a character string. On the processing setting screen 100, an input text box 101, a font setting list button 102, parameter set list buttons 103 and 104, and an OK button 105 are displayed. Examples of fonts whose selection is accepted by the font setting list button 102 include a True Type Font (hereinafter abbreviated as TTF), which is an example of an outline font, and a stroke font. When the TTF is selected by the font setting list button 102, the CPU 71 accepts the input of the parameter set list buttons 103 and 104 in order to accept the selection of the parameter set for each of the outline and the filled portion. Display in state. Here, the parameter set list button 103 is a button for accepting selection of a contour line parameter set, and the parameter set list button 103 is a button for accepting selection of a parameter set for a filled portion. Thus, when the font is TTF, the user can select a parameter set for each of the outline and the filled portion. When a stroke font is selected by the font setting list button 102, the CPU 71 displays the parameter set list button 104 in an invalid state in which no input is accepted in order to have one parameter set that accepts the selection. When the user finishes inputting the processing setting screen 100, the user selects the OK button 105.

  Returning to FIG. 8, next, the CPU 71 executes steps S3 to S7. If YES is determined in the step S7, the CPU 71 determines whether or not the font selected by the font setting list button 102 is TTF (S41). If it is determined that the selected font is TTF (S41: YES), the CPU 71 determines whether a different parameter set has been selected with the parameter set list button 103 and the parameter set list button 104 (S43). If it is determined that a different parameter set has been selected (S43: YES), the CPU 71 determines whether or not the same parameter set as the input parameter set is the value in the layer table 400 based on the input of the parameter set list button 103. (S45). If it is determined that the same parameter set does not exist in the layer table 400 (S45: NO), the parameter set and object ID values in the layer table 400 are the values input to the parameter set list button 103 in the empty column parameter set column. Is stored. Also, a value obtained by adding A to the end of the number obtained by incrementing the maximum value by 1 among the number portions of the values stored in the object ID column is stored in the object ID column of the row storing the parameter set. (S49). On the other hand, when determining that the same parameter set exists in the layer table 400 (S45: YES), the CPU 71 sets the numerical part of the value stored in the object ID column to the object ID column in the same row as the same parameter set. Of these, the value obtained by adding A to the end of the number obtained by incrementing the maximum value by 1 is stored (S47).

  Next, the same processing is performed on the filled portion. That is, based on the input of the parameter set list button 104, the CPU 71 determines whether or not the same parameter set as the input parameter set exists as the value of the layer table 400 (S51). If it is determined that the same parameter set does not exist in the layer table 400 (S51: NO), the parameter set and object ID values in the layer table 400 are the values input to the parameter set list button 104 in the empty parameter set column. Is stored. In addition, a value obtained by adding B to the end of the number obtained by incrementing the maximum value by 1 among the number portions of the values stored in the object ID column is stored in the object ID column of the row storing the parameter set. (S55). On the other hand, when determining that the same parameter set exists in the layer table 400 (S51: YES), the CPU 71 sets the numerical part of the value stored in the object ID column to the object ID column in the same row as the same parameter set. Of these, the value obtained by adding B to the end of the number obtained by incrementing the maximum value by 1 is stored (S53).

  FIG. 10 shows a layer table 400 when, for example, the parameter set A is applied to the contour line and the parameter set B is applied to the filled portion. In this case, 1A is stored in the column of the object ID in the row that is the parameter set A, and 1B is stored in the column of the object ID in the row that is the parameter set B.

  Returning to FIG. 8, when the CPU 71 determines NO in step S <b> 41 and when NO is determined in step S <b> 43, the CPU 71 executes steps S <b> 11 to S <b> 15. Moreover, CPU71 performs step S17 after execution of step S13, S15, S53, S55. Thereby, when the parameter set applied to the contour line is different from the parameter set applied to the filled portion, different display is made in the layout area 92 for the contour line and the filled portion. Thereby, the user can easily determine that different parameter sets are applied to the contour line and the filled portion. If CPU71 performs step S19 and it determines NO in step S19, it will return to step S3, and if it determines YES in step S19, a setting reception process will be complete | finished.

  Here, the outline and the filled portion are examples of the division processing pattern region.

As mentioned above, according to 2nd Embodiment demonstrated, there exist the following effects.
In step S5, the CPU 71 accepts selection of a parameter set for each of the contour portion and the painted portion, and applies a layer ID to each of the contour portion and the filled portion in steps S45 to S55. Accordingly, in a configuration in which one object Obj can be divided into a plurality of printing units, the printing units to which the same parameter set is applied have the same display color, and the printing units to which different parameter sets are applied. Is displayed in the layout area 92 in a different display color. Thereby, in the display of the layout area 92, when the object Obj includes a plurality of printing units, the user can easily determine a plurality of printing units having the same processing conditions.

(Third embodiment)
Next, display processing according to the third embodiment will be described with reference to FIG. Also in the third embodiment, the CPU 71 executes a setting reception process. The setting reception process according to the third embodiment differs from the setting reception process according to the first embodiment in the processing content of step S17. In step S <b> 17 in the first embodiment, it has been described that the display color is displayed in accordance with the layer ID based on the layer table 400. In the third embodiment, all objects Obj are displayed in the same display color regardless of the layer ID.

  The CPU 71 starts the display process in response to the pointer 95 being placed in the display area of one object Obj while a plurality of objects Obj are displayed in the layout area 92 (FIG. 6). When the mouse 78 is clicked with the pointer 95 being placed in the display area of the object Obj, the CPU 71 sets the object Obj on which the pointer 95 is placed to the selected state. Note that the selection state is a state in which acceptance of an editing operation of the object Obj such as deletion is enabled.

  When the display process is started, the CPU 71 causes the first selected graphic 110 surrounding the object Obj on which the pointer 95 is arranged to be superimposed on the object Obj on which the pointer 95 is arranged (S21). Here, as shown in FIG. 13, the first selected figure 110 is a rectangular figure surrounding the object Obj1 and having a solid line as a frame line. Next, the CPU 71 determines whether or not a plurality of object IDs are associated with the layer ID corresponding to the object ID of the object Obj surrounded by the first selected graphic 110 in the layer table 400 (S23). ). Here, in the layer table 400, an object Obj having an object ID associated with a layer ID corresponding to the object ID of the object Obj surrounded by the first selected graphic 110 is referred to as a corresponding object. If it is determined that a plurality of object IDs are associated (S23: YES), the CPU 71 displays the second selected graphic 111 surrounding the corresponding object superimposed on the corresponding object (S25), and proceeds to step S27. Here, as shown in FIG. 13, the second selected figure 111 is a rectangular figure surrounding the object Obj4 and having a broken line as a frame line. On the other hand, if it is determined that a plurality of object IDs are not associated (S23: NO), the CPU 71 skips step S25 and proceeds to step S27.

  Next, the CPU 71 determines whether or not there is an object ID associated with a layer ID different from the layer ID corresponding to the object ID of the object Obj surrounded by the first selected graphic 110 in the layer table 400. Judgment is made (S27). That is, it is determined whether or not the data of the object Obj other than the corresponding object is included in the layer table 400. If it is determined that there is an object ID associated with a different layer ID (S27: YES), the CPU 71 changes the display of the object Obj other than the corresponding object to a display of 50% transparency (S29), and proceeds to step S31. On the other hand, when determining that there is no object ID associated with a different layer ID (S27: NO), the CPU 71 skips step S29 and proceeds to step S31.

  By executing steps S25 and S29, as shown in FIG. 13, the object Obj3 to which the same parameter set as the object Obj1 on which the pointer 95 is arranged is applied is displayed with the second selected graphic 111 attached thereto. Further, the objects Obj2 and Obj4 to which the parameter set different from the object Obj1 on which the pointer 95 is arranged are displayed with 50% transparency. Thereby, even when a plurality of objects Obj are displayed, the user can easily determine the objects Obj having the same processing conditions.

  Returning to FIG. 12, next, the CPU 71 determines whether or not the pointer 95 has been removed from the object Obj on which the pointer 95 has been placed (S31). If it is determined that the pointer 95 is not detached (S31: NO), the CPU 71 returns to step S31 and repeatedly executes step S31 until it is determined YES. On the other hand, if it is determined that the pointer 95 has been removed (S31: YES), the CPU 71 erases the display of the first selected graphic 110 and the second selected graphic 111 from the layout area 92 (S33). Next, the CPU 71 updates the display of all objects Obj to a display with 0% transparency (S35), and ends the display process.

  Here, the 1st selection figure 110 and the 2nd selection figure 111 are examples of a figure of the same shape. The process of displaying the pointer 95 in the layout area 92 and accepting the placement of the pointer 95 in the display area of the object Obj is an example of a selection process. The display with the first selected graphic 110 and the second selected graphic 111, which are the same rectangular graphic, is an example of a common display mode.

As mentioned above, according to 3rd Embodiment demonstrated, there exist the following effects.
In the display process, the CPU 71 has the same parameter set as the object Obj on which the pointer 95 is arranged, that is, the object Obj on which the plurality of processing conditions are the same, and is superimposed on the object Obj on which the pointer 95 is arranged. A second selected graphic 111 that is the same shape as the first selected graphic 110 is superimposed and displayed. Thereby, in the display of the layout area 92, the user can easily determine the object Obj having the same processing condition when the processing pattern includes a plurality of objects Obj.

In addition to the above embodiment, the following configuration may be added.
For example, in the first embodiment, it has been described that the objects Obj having the same parameter set are displayed in the same display color. In addition to this configuration, the objects Obj whose processing conditions are approximate may be displayed in a display mode different from the display mode of the objects Obj whose display modes are similar to each other. Here, the approximate display mode includes, for example, display in a so-called similar color in which the hue of the display color approximates, display in which the hue is the same, and different in saturation or brightness, or a combination of these. The processing conditions are approximated, for example, when one of a plurality of conditions, for example, only the scanning speed is focused and the value difference is smaller than a predetermined value. Specifically, the machining conditions where the scanning speed is 4500 m / s and the machining conditions where the scanning speed is 5000 m / s are set as approximate machining conditions. In other words, since 500 m / s, which is the difference between 4500 m / s and 5000 m / s, is smaller than the threshold, it is assumed that the machining conditions are approximate. Further, for example, when the value of at least one condition among the plurality of conditions is the same and the value of at least one condition is different, the processing condition can be regarded as approximate. For example, it can be approximated when the values of the scanning speed are the same and the values of conditions other than the scanning speed are different. Thereby, the object Obj which is an approximate processing condition can be displayed in an approximate display mode. The user can intuitively discriminate between objects Obj whose processing conditions are approximate.

Needless to say, the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the spirit of the present invention.
(Example 1)
For example, as an example of the division processing pattern, the outline of the TTF and the filled portion are illustrated in the second embodiment, but the present invention is not limited to this. As an example of the division processing pattern, for example, an object Obj5 that is a graphic object as illustrated in FIG. 14 may have a configuration in which the parameter set differs between the outline and the filled portion. For example, in order to shorten the processing time for the filled portion, for example, the scanning speed may be increased, and for the contour line, for example, the laser intensity may be increased to increase the processing depth. In FIG. 14, it is assumed that the filled portion is composed of a plurality of line segments extending in the left-right direction on the paper surface. For example, when the vertical interval between the line segments is wide, the boundary lines on the left and right ends of the processed pattern may be blurred. Therefore, the outline of the figure can be clarified by using the boundary lines at the left and right ends of the processed pattern as contour lines.

(Example 2)
As an example of the division processing pattern, for example, an object Obj6 that is an object of a QR code as shown in FIG. 15 may have a different parameter set between the base portion and the code portion. Here, the code portion is a black portion of the QR code, and the base portion is a rectangular figure having an outer shape of the QR code as an outer shape. For example, in order to make the processing depth of the code portion deeper than that of the base portion, for example, the laser intensity of the code portion may be made larger than that of the base portion. Some materials of the workpiece W are difficult to read by a barcode reader. Specifically, in the case of a material having a metallic luster such as aluminum, for example, the barcode reader may not be able to accurately read the difference between the code portion and other than the code portion. In this case, it is known that the barcode reader can accurately read the base portion by printing with the laser beam L having a weak laser intensity.

  In addition, in any of (Another Example 1) and (Another Example 2), similar to the second embodiment, two parameter sets may be received on the processing setting screen 100 and a setting receiving process may be executed. . Thereby, two parameter sets can be received for one object Obj. The user can easily determine that different processing conditions are applied to the divided processing pattern.

  In the above description, for example, in the first embodiment, the objects Obj to which the same parameter set is applied are displayed in the same display color. However, the present invention is not limited to this. For example, as in the third embodiment, the objects Obj to which the same parameter set is applied may be displayed with a figure having the same shape such as a rectangular figure. In the third embodiment, it has been described that when the pointer 95 is placed on the object Obj, the object Obj to which the same parameter set is applied is displayed with the second selected graphic 111 attached thereto, but the present invention is not limited to this. . As in the first embodiment, the object Obj on which the pointer 95 is arranged and the object Obj to which the same parameter set as the object Obj is applied have the same display color and different parameter sets are applied. The display color may be different from that of Obj.

  In the above description, the processing conditions have been described using the parameter set table 200, but the included conditions are not limited.
