  The carriage 15 includes a cartridge holder 26 and a vertical drive mechanism that drives the cartridge holder 26 in the vertical direction. The cartridge holder 26 detachably holds the cutter cartridges 14 and 17. When performing a cutting operation on the workpiece W, the cutter cartridge 14 is mounted on the cartridge holder 26. Although not shown in detail, the cutter cartridge 14 includes a cylindrical case extending in the vertical direction and a cutter extending along the central axis thereof. The cutter protrudes downward by a predetermined dimension from the lower end of the case, and a blade is formed at the lower end.

  When performing a drawing operation on the workpiece W, the pen cartridge 17 is mounted on the cartridge holder 26. The pen cartridge 17 includes a cylindrical case extending in the vertical direction and a pen held by the case. The tip of the pen projects downward from the lower end of the case.

Is provided. Thereby, when the cartridge corresponding to the cutting or drawing operation is not mounted on the cartridge holder 26, it is possible to notify the user of replacement. Further, the cutting device 11 of the present embodiment is also provided with a scanner unit 28 (shown only in FIG. 2) for reading a surface pattern such as an original image held by the holding member 16.

  As shown in FIG. 2, the cutting device 11 includes a control circuit 29 as control means. The control circuit 29 is composed mainly of a computer (CPU) and controls the entire cutting apparatus 11. The control circuit 29 is connected to the LCD 19, various operation switches 20, the scanner unit 28, and the detection sensor 38, and is also connected to a ROM 30, a RAM 31, and an EEPROM 32. The control circuit 29 is connected to drive circuits 33, 34, and 35 for driving the X-axis motor 25, the Y-axis motor 23, and the Z-axis motor 27, respectively. Furthermore, an external memory 36 such as a USB memory can be connected to the control circuit 29.

  The ROM 30 has various controls such as an operation control program for controlling a cutting operation and a drawing operation, a machining data creation program for creating and editing machining data, that is, cutting data and drawing data, and a display control program for controlling the display of the LCD 19. The program is stored. The RAM 31 temporarily stores data and programs necessary for various processes. The EEPROM 32 or the external memory 36 stores pattern data indicating the shape of a large number of patterns, cutting data created for cutting a pattern having the predetermined shape, and drawing data for performing a drawing operation.

  The control circuit 29 executes the cutting operation and the drawing operation based on the cutting data and the drawing data by executing the operation control program. The cutting data is data indicating a cutting position for cutting the workpiece W with a cutter from above, and is constituted by a set of coordinate value data indicating the cutting position in the XY coordinate system. The control circuit 29 is in a state where the cutter cartridge 14 is mounted in the cartridge holder 26, and based on the cutting data, the X-axis motor 25, the Y-axis motor 23, and the Z-axis motor 27 via the drive circuits 33, 34, and 35. To control each. Thus, the workpiece W held by the holding member 16 is moved in the front-rear direction, and the cutter cartridge 14 mounted on the carriage 15, that is, the cartridge holder 26 is moved in the left-right direction, thereby cutting the workpiece W. Operation is performed.

  The drawing data is data indicating a drawing position at which drawing is performed by placing a pen on the upper surface of the workpiece W, and is composed of a set of coordinate value data indicating the drawing position in the XY coordinate system. The control circuit 29 has the pen cartridge 17 attached to the cartridge holder 26, and based on the drawing data, the X-axis motor 25, the Y-axis motor 23, and the Z-axis motor 27 via the drive circuits 33, 34, and 35. To control each. As a result, the workpiece W held by the holding member 16 is moved in the front-rear direction, and the pen cartridge 17 mounted on the carriage 15, that is, the cartridge holder 26 is moved in the left-right direction, thereby drawing on the workpiece W. Operation is performed.

  In the present embodiment, the control circuit 29 executes each process as a machining data creation device that creates machining data for the workpiece W by executing the machining data creation program. In this case, both cutting data and drawing data are created as the processing data. The machining data creation program is not limited to the program stored in advance in the ROM 30, but may be recorded on an external recording medium such as an optical disk and read from the recording medium. Furthermore, it may be downloaded from the outside via a network.

  For example, when the user designates a pattern to be cut from the patterns stored in the EEPROM 32 or read by the scanner unit 28, the cutting data is created within the processable range A. This is performed by obtaining a contour line expressing the pattern and creating cutting data for cutting along the contour line. For creating drawing data, the user designates characters to be drawn from characters, marks, diagrams, etc. (hereinafter referred to as characters, etc.) stored in advance in the EEPROM 32 or read by the scanner unit 28, for example. Then, the character or the like is arranged in the processable range A, and drawing data for drawing a line constituting the character or the like is generated.

  At this time, in this embodiment, the control circuit 29 cuts a plurality of patterns F from the workpiece W to obtain a plurality of cut parts P, and also describes each pattern F (cutting) as described later in the description of the operation. When processing data for drawing the identification information on the part P) is created, the following processing is performed. That is, the control circuit 29 first performs a process of accepting designation of a plurality of patterns F to be cut by the operation of various operation switches 20 by the user. At the same time, with respect to each designated pattern F, an identification information acquisition process for acquiring identification information for identifying the other pattern F is performed. The identification information may be set automatically, or may be input by operating the various operation switches 20 by the user.

  Then, the control circuit 29 performs a pattern reversal process for generating a reversal pattern F ′ obtained by reversing each designated pattern F (front and back reversal). This pattern inversion process is performed by, for example, inverting the shape data (contour line) of each pattern F to the left and right (mirror inversion) about the axis in the front-rear direction. It can be implemented even if it is reversed. In this embodiment, the control circuit 29 arranges each designated pattern F with respect to the workable range A corresponding to the size of the workpiece W, and the arranged pattern F is related to the whole workable range A. It is designed to reverse. In the pattern reversal process, the individual patterns F within the processable range A may be reversed with respect to the central axis in the front-rear direction of each pattern F.

  Next, the control circuit 29 performs an identification information arrangement process for arranging the acquired identification information inside each reversal pattern F ′. In the present embodiment, after the inverted pattern F ′ is generated by the pattern inversion process, the process of arranging the identification information is performed inside each inverted pattern F ′. At this time, when the character information attached to each pattern F is acquired as the identification information, the control circuit 29 stores the character information in each pattern, in this case, the inverted pattern F ′. The drawing size, that is, the font size of printing is adjusted. If the character information does not fit in the reverse pattern F ′, the character information is changed to a drawable mark, for example, a short parallel line that can be identified by the number.

  Thereafter, cutting data for cutting each reversal pattern F ′ from the workpiece W and processing data generation for generating drawing data for drawing each identification information at a position arranged inside each reversal pattern F ′ Perform the process. Accordingly, the various operation switches 20 function as a designation unit, and the control circuit 29 functions as an acquisition unit, a reversing unit, a pattern arranging unit, an identification information arranging unit, and a processed data generating unit. Of course, the control circuit 29 can generate only cutting data or only drawing data.

  Further, in the present embodiment, when the cutting circuit 11 performs the machining operation, the control circuit 29 displays a message for prompting the workpiece W to be set face down on the LCD 19 for notification. ing. Therefore, the control circuit 29 also functions as a notification information generating unit that generates a message that prompts the user to set the workpiece W face down.

  Here, as a specific example, as shown in FIG. 6, for example, in the case of producing a decoration “O” made of paper, two circular left and right eyes, a large circular face, a horizontally long shape After obtaining four cut parts P (1) to P (4) of a rectangular body, they are combined while being partially overlapped. At this time, cutting parts P (1) to P (4) are obtained by cutting four patterns F (1) to F (4) as shown in FIG. Can be obtained.

  In this case, the user designates four patterns F (1) to F (4), operates various operation switches 20, and displays at least these patterns F (1) to F (4) on the screen of the LCD 19. The layout is instructed so that it partially overlaps. At the same time, the user operates the various operation switches 20 so that characters indicating the pattern numbers “1”, “2”, “3”, and “4” are assigned to the patterns F (1) to F (4). Information is set and input as identification information.

  In the present embodiment, the control circuit 29 recognizes the overlapping order and overlapping position of each pattern F (1) to F (4), and identifies position information indicating the overlapping position between two patterns F that overlap at least partially. Set as information. Here, based on the order in which the patterns F are overlapped, information on the outline of the overlapping position of the pattern F that is below is set as identification information for the pattern F that is above. As shown in FIG. 7A, the control circuit 29 performs a pattern placement process for placing the designated patterns F (1) to F (4) on the processable range A. At the same time, the information on the outline of the overlapping position as the position information and the character information “1”, “2”, “3”, “4” attached to each pattern F are used as identification information. get.

  Then, as shown in FIG. 7B, the control circuit 29 performs reversal processing of the patterns F (1) to F (4) arranged in the processable range A, and then each reversal pattern F ′. Identification information is arranged for (1) to F ′ (4). When the identification information is arranged, the outline of the overlapping position of the inverted pattern F ′ of the lower pattern F is arranged with a broken line with respect to the inverted pattern F ′ of the upper pattern F. Specifically, the contour line of the pattern F (4) is arranged in the reversal pattern F ′ (3), and the contour line of the pattern F (3) is disposed in the reversal patterns F ′ (1) and F ′ (2), respectively. Is placed.

  At the same time, character information indicating the pattern numbers “1”, “2”, “3”, and “4” is arranged as identification information for each of the inverted patterns F ′ (1) to F ′ (4). The In this case, the character information is arranged inside the corresponding pattern (inverted pattern F ′), at a position not overlapping with another pattern F, that is, the inverted pattern F ′, and further not overlapping with the contour line. Thus, the control circuit 29 cuts the reversal patterns F ′ (1) to F ′ (4) from the workpiece W and the reversal patterns F ′ (1) to F ′ ( Drawing data for drawing each piece of identification information, that is, outline and character information, is created at the position arranged inside 4).

  Next, the operation of the above configuration will be described with reference to FIGS. The flowcharts of FIGS. 3 to 5 show a processing procedure of processing data creation executed by the control circuit 29 when processing data creation processing is instructed by a user's operation of various operation switches 20. FIG. 3 shows a main processing procedure from machining data creation to machining operation execution. 4 shows a detailed processing procedure for creating cutting data in step S5 of FIG. 3, and FIG. 5 shows a detailed processing procedure for creating drawing data in step S6 of FIG. Hereinafter, the pattern F (decorative object O) shown in FIGS. 6 and 7 will be described as a specific example.

  In FIG. 3, first, in step S <b> 1, a pattern F selection designation is accepted based on the operation of various operation switches 20 by the user. At this time, the user can designate a plurality of patterns F, and the designated patterns F are displayed on the LCD 19. In step S2, layout processing of a plurality of designated patterns F is performed. In the example of creating the ornament O shown in FIG. 6, in this case, a plurality of patterns F (1) to F (4) are designated, and these patterns F (1) to F (4) are as shown in FIG. Are laid out in a form with some overlap. The user can designate the layout of the patterns F (1) to F (4) by operating the various operation switches 20.

  In step S <b> 3, it is determined whether or not each layout pattern F has an overlap. That is, it is determined whether at least one of the laid out patterns F is laid out so as to overlap another pattern F. If there is an overlap (Yes in step S3), the overlapping order of the patterns F that are laid out and overlapped is specified in step S4, and the process proceeds to step S5. If there is no overlap (No in step S3), the process proceeds to step S5 as it is. In the example of FIG. 6, since there is an overlap, the pattern F (3) is superimposed on the pattern F (4), and the pattern F (1) and the pattern F (2) are formed on the pattern F (3). The overlapping order such as overlapping is specified.

  In step S5, a cutting data creation process is executed. In step S6, a drawing data creation process is executed. These processes will be described later. After the cutting data and drawing data are created, drawing and cutting operations on the workpiece W, that is, creation of the cutting part P, can be executed by operating the various operation switches 20 of the user. Needless to say, the created cutting data and drawing data can be stored in the external memory 36.

  When drawing and cutting operations are performed, the workpiece W is held by the holding member 16 and is set so as to be inserted onto the platen 13, but the user turns the workpiece W upside down (the back side). Is held by the holding member 16 in a state of facing upward. At this time, in step S <b> 7, a message for prompting the workpiece W to be set face down is displayed on the LCD 19. When the user performs a start operation, a drawing process on the upper surface of the workpiece W is performed in a state where the pen cartridge 17 is mounted in step S8. Subsequently, in step S9, a cutting process is performed on the workpiece W with the cutter cartridge 14 mounted.

  The flowchart of FIG. 4 shows the detailed procedure of the cutting data creation process in step S5. In step S <b> 11, as in step S <b> 3, it is determined whether or not there is an overlap for a plurality of designated patterns F. When there is an overlap (Yes in step S11), in step S12, the patterns F are arranged in positions that do not overlap each other within the processable range A. In the example of the patterns F (1) to F (4) in FIG. 6, for example, as shown in FIG. 7A, the patterns F (1) to F (4) are arranged at positions where they do not overlap. When there is no superposition (No in step S11), each pattern F is arranged as it is within the processable range A, and the process proceeds to step S13.

  In the next step S13, the inversion process of each pattern F (1) to F (4) arranged in the processable range A is performed. In this case, the arranged patterns F are inverted with respect to the entire processable range A, and as shown in FIG. 7B, the inverted patterns F ′ (1) to F ′ (4) are present in the processable range A. Will be placed. In step S14, cutting data for cutting the arranged inverted patterns F ′ (1) to F ′ (4) is created, and the process ends.

  Next, the flowchart of FIG. 5 shows the detailed procedure of the drawing data creation process in step S6 of FIG. In step S21, character information as identification information regarding each pattern F is acquired. The character information may be input by the user, or character information may be associated with each pattern in advance and stored in the EEPROM 32 or the like, and the character information may be set. In this case, the process of the next step S22 is skipped. Also, numbers may be automatically set in the order in which each pattern is selected. In step S22, each character information is stored in association with each pattern F. In the example of FIG. 7A, the character information D of “1”, “2”, “3”, and “4” is acquired and stored for each of the patterns F (1) to F (4). In the next step S23, the contour of each inverted pattern F ′ is specified.

  From step S24 to step S34, processing is performed in order for each pattern F. First, in step S24, it is determined whether one pattern F is overlaid with another pattern F or not. The If there is an overlap (Yes in step S24), it is determined in step S25 whether there is another pattern F positioned below the one pattern F. If there is no overlay (No in step S24), and if there is no other pattern F that is underneath (No in step S25), the process proceeds to step S28 described later.

  If there is another pattern F located below one pattern F (Yes in step S25), in step S26, as the position information indicating the overlapping position, the outline of the overlapping portion of the pattern F located below The shape is acquired. In step S27, the outline of the overlapping portion of the pattern F positioned below is arranged in an inverted state with respect to the inverted pattern F ′ of the one pattern F positioned above. In this case, as shown in FIG. 7B, the inverted contour line L is, for example, a broken line. In the example of FIG. 7B, the outline L of the overlapping portion of the inverted pattern F ′ (4) is arranged in the inverted pattern F ′ (3), and the inverted pattern F ′ (2) and the inverted pattern F ′ (1). ), The contour lines L of the overlapping portions of the inverted pattern F ′ (3) are respectively arranged.

  In the next step S28, whether or not the character information D can be drawn in the one pattern F (inverted pattern F ′), that is, whether or not the character information D can enter the space in the inverted pattern F ′. Is judged. In this case, when the contour line L exists in the reverse pattern F ′, it is determined whether or not the character information D can be arranged so as not to overlap the contour line L. When the character information D is entered (Yes in step S28), the character information D associated with the reverse pattern F ′ is arranged in step S29. Regarding the character information D, it is important that the user can recognize what is drawn, and it is allowed to protrude slightly from the reversal pattern F ′ or to overlap the outline L. You may do it.

  On the other hand, when the character information D does not enter the space in the reverse pattern F ′, that is, when the character information D protrudes greatly or overlaps the contour line L (No in step S28), in step S30, A process of reducing the size of the character information D to a size that can be arranged is performed in accordance with the size of the pattern F (inverted pattern F ′). In step S31, it is determined whether the character size of the reduced character information D is equal to or smaller than a predetermined size that cannot be drawn. If the size of the character of the reduced character information D is larger than the predetermined size, that is, it is a drawable size (No in step S31), the process proceeds to step S29, and the character reduced in the reverse pattern F ′ Information D is arranged.

  If the character size of the reduced character information D is equal to or smaller than the predetermined size (Yes in step S31), the character information D is changed to another drawable mark in step S32, and the reversed pattern F ′ Placed inside. In this case, it is possible to convert the character information D into a mark having a simple shape that can be identified by the user, for example, the number is represented by the number of short lines (or the number of points). In step S33, a display notifying the user that the character information D has been changed to a mark is performed, and the process proceeds to step S34.

  In step S34, it is determined whether or not the processing has been completed for all patterns F. If an unprocessed pattern remains (No in step S34), the process proceeds to step S24, and the same process is performed for the next pattern F. When processing for all patterns F is completed (Yes in step S34), drawing data creation processing for character information D and contour L is performed in step S35, and the processing ends. In the example of FIG. 7B, the character information D and outline L of “1” are arranged at the position of the reverse pattern F ′ (1), and “2” is set at the position of the reverse pattern F ′ (2). Character information D and contour line L are arranged. Further, the character information D and outline L of “3” are arranged at the position of the reverse pattern F ′ (3), and the character information D of “4” is arranged at the position of the reverse pattern F ′ (4). Drawing data for drawing them is created.

  In the cutting device 11, the cutting operation and the drawing operation are performed on the workpiece W turned upside down using the cutting data and the drawing data created as described above. As a result, the reversed pattern F ′ that is reversed when viewed from the top surface is cut (cut out) from the workpiece W, and the identification information, that is, the character information D and the contour line L are drawn on the top surface. Here, by using the cutting data for cutting each reversal pattern F ′, a cut part P in which the pattern F is reversed, that is, turned upside down is obtained. At the same time, identification information (character information D and contour line L) is drawn on the back surface of the cut parts P.

  Accordingly, as shown in the example of FIG. 6, a plurality of patterns F are cut from the workpiece W to create a plurality of cutting parts P, and then the plurality of cutting parts P are combined to form one decoration object O. In this case, when the user looks at the back surface of each cutting part P, the user can easily understand at which position the cutting part P is combined. In addition, since the contour line L of the overlapping position of the other cutting parts P coming below is drawn on the back surface of each cutting part P, the user can perform alignment when pasting the plurality of cutting parts P together. The work can be done more easily and reliably.

  Thus, according to the present embodiment, the following actions and effects can be obtained. That is, the control circuit 29 generates a reversed pattern F ′ obtained by inverting each designated pattern F, and arranges the acquired identification information inside each of the reversed patterns F ′. Then, cutting data for cutting each inverted pattern F ′ from the workpiece W and drawing data for drawing the identification information at the arranged position are generated. As a result, when a plurality of patterns F are cut from the workpiece W by the cutting device 11 and these cutting parts P are combined, it is possible to create processing data that allows the plurality of cutting parts P to be easily identified. An excellent effect can be obtained. In this case, it is a matter of course that the inconvenience that the identification information appears on the surface of the cutting part P can be prevented.

  Here, the drawing data for drawing the identification information described above is data indicating where the pen tip is to be plotted with respect to the processable range A (entire area). In this case, it is possible to arrange the identification information before the pattern F is inverted and to invert the position of the identification information simultaneously with the pattern F inversion process. After generating the inverted pattern F ′ obtained by inverting the identification information, the identification information is arranged inside each inverted pattern F ′. Thereby, it becomes easier for the user to understand the arrangement work. Of course, the identification information can be arranged at an appropriate position.

  In this embodiment, the control circuit 29 generates a message for informing when the machining operation is performed in the cutting device 11 and prompts the workpiece W to be set face down, and executes the machining operation. The system is configured to notify a message. This can prompt the user to set the workpiece W face down. As a result, correct processing can be performed.

  In the present embodiment, the control circuit 29 arranges a plurality of designated patterns F with respect to the processable range A corresponding to the size of the workpiece W, and then relates to the entire processable range A. Each pattern was configured to be reversed. In this case, the plurality of patterns F arranged in the processable range A can be individually inverted. However, by inverting the entire processable range A, the user can perform a more easily understandable operation. Can do. Further, for example, when the coloring (gradation) that changes depending on the position is performed on the surface of the workpiece W, it is possible to obtain the cut part P in the coloring state that the user thought.

  At this time, particularly in the present embodiment, the control circuit 29 acquires the character information D attached to each pattern F as identification information, and stores the character information D in each pattern F (inverted pattern F ′). The drawing size was adjusted to fit. Thereby, when the character information D as identification information is drawn, it becomes possible to draw in the cut part P reliably. Further, when the character information D does not fit in the pattern F (reversal pattern F ′), the character information D is changed to a drawable mark, so that the pattern F (cutting part) does not fit the character information D. Even when P) is small, the mark can be drawn to enable identification.

  In particular, in the present embodiment, the control circuit 29 lays out a plurality of designated patterns F so as to at least partially overlap each other, arranges each pattern F with respect to the processable range A, and sets two patterns F. Position information indicating an overlapping position between them is acquired as identification information, and an outline L of the overlapping position as identification information is arranged on at least one of the two overlapping patterns F. As a result, it is possible to more easily perform the user's alignment operation when combining a plurality of cutting parts P so as to partially overlap each other. At this time, since the contour line L of the overlapping position of the lower pattern F is arranged with respect to the upper pattern F based on the order in which the plurality of patterns F are overlapped, the operation is further facilitated.

  Further, in the present embodiment, the control circuit 29 acquires position information indicating the overlapping position between the two patterns F as identification information and creates drawing data of the contour line L, and adds to each pattern F. The obtained character information D is acquired as identification information, and the character information D is arranged at a position that does not overlap with other patterns F and contour lines L. As a result, both the character information D and the contour line L are drawn, which makes it easier to work. In addition, it is possible to prevent the character information D and the contour line L from overlapping and becoming difficult to understand.

(2) Second and Third Embodiments and Other Embodiments FIG. 8 and FIG. 9 show a second embodiment of the present invention. The second embodiment is different from the first embodiment in a processing procedure (software configuration) for processing data creation executed by the control circuit 29, that is, a processing data creation program. Since the configuration of the cutting device 11 as the processing data creation device is the same as that in the first embodiment, new illustration and description are omitted.

  FIG. 8 shows a main processing procedure from machining data creation to machining operation execution. Further, the flowchart of FIG. 9 shows a detailed processing procedure for creating cutting data and drawing data in step S40 of FIG. Hereinafter, differences from the first embodiment (flowcharts of FIGS. 3 to 5) will be described. That is, in FIG. 8, after the processing of steps S <b> 1 to S <b> 4 is performed in the same manner as in the first embodiment, in step S <b> 40 instead of steps S <b> 5 and S <b> 6 in FIG. The creation process is executed. After the process in step S40, the processes in steps S7 to S9 are performed as in the first embodiment.

  Next, with reference to FIG. 9, the detailed processing for creating the cutting data and drawing data in step S40 will be described. First, in step S41, as in step S11, it is determined whether or not there is an overlap for a plurality of designated patterns F. If there is an overlap (Yes in step S41), in step S42, the patterns F are arranged in positions that do not overlap each other within the processable range A. When there is no superposition (No in step S41), each pattern F is arranged as it is within the processable range A, and the process proceeds to step S43. In step S43, as in step S21, character information as identification information regarding each pattern F is acquired, and in step S44, each character information is stored in association with each pattern F.

  From step S45 to step S56, processing is sequentially performed for each pattern F. First, in step S45, it is determined whether one pattern F is overlaid with another pattern F or not. The If there is an overlap (Yes in step S45), it is determined in step S46 whether there is another pattern F located below the one pattern F. If there is no superposition (No in step S45) and if there is no other pattern F that is underneath (No in step S46), the process proceeds to step S49 described later.

  If there is another pattern F located under one pattern F (Yes in step S46), in step S47, as the position information indicating the overlapping position, the outline of the overlapping portion of the pattern F located below The shape is acquired. In step S48, the outline L of the portion where the pattern F positioned below is overlapped with the pattern F positioned above is arranged in accordance with the overlapping position. In the next step S49, the corresponding character information D is arranged in the one pattern F. In step S50, it is determined whether or not the character information D can enter the space in the one pattern F. In this case, when the contour line L exists in the pattern F, it is determined whether or not the character information D can be arranged so as not to overlap the contour line L. When the character information D is entered (Yes in step S50), the arrangement state of the character information D is displayed on the LCD 19 in step S51. Although not shown in detail, in this display, a plurality of patterns F are arranged in the processable range A, and the character information D and the outline L are arranged in each pattern F.

  On the other hand, when the character information D does not enter the space in the pattern F (No in step S50), the size of the character information D can be arranged in accordance with the size of the pattern F in step S52. In step S53, it is determined whether or not the character size of the reduced character information D is equal to or smaller than a predetermined size at which rendering is impossible. If the character size of the reduced character information D is larger than the predetermined size, that is, a size that can be drawn (No in step S53), the process proceeds to step S51, and the character information D reduced in the pattern F is performed. Is displayed.

  If the character size of the reduced character information D is equal to or smaller than the predetermined size (Yes in step S53), the character information D is changed to another drawable mark in step S54, and the reverse pattern F ' Placed inside. In step S55, a display notifying the user that the character information D has been changed to a mark is performed, and the process proceeds to step S56. In step S56, it is determined whether or not processing has been completed for all patterns F. If an unprocessed pattern remains (No in step S56), the process proceeds to step S45, and the same process is executed for the next pattern F.

  When the processing for all the patterns F is completed (Yes in step S56), the position of the character information D and the shape of the contour line L are reversed with respect to the entire processable range A in step S57. In step S58, drawing data is created based on the position of the inverted character information D and the contour line L. In step S59, the pattern F is reversed with respect to the entire processable range A, and in step S60, cutting data for the reversed pattern F ′ is created. Thus, drawing data and cutting data similar to those in the first embodiment are obtained. Therefore, the second embodiment can also provide the same operations and effects as those of the first embodiment.
