Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a pattern display device for a sewing device, and in particular, a pattern that is sequentially reduced under a predetermined mode to display a plurality of reduced patterns on a display. Related information (thread color, number of colors, sewing time, etc.) related to embroidery sewing can be displayed.
[0002]
[Prior art]
  Conventionally, in a sewing apparatus such as an embroidery sewing machine, pattern data of a plurality of embroidery patterns is stored in a control device or in an external recording medium, and a desired pattern is searched while displaying the pattern on the display and switching the display screen. When the pattern is selected, the pattern data of the selected pattern can be read and embroidery stitched. Various techniques have been proposed and put to practical use as a pattern display method at the time of pattern selection.
[0003]
  For example, in the sewing machine described in Japanese Patent Laid-Open No. 5-42268, pattern data of a plurality of embroidery patterns is stored in a nonvolatile memory of a control unit of the sewing machine, and a specified pattern group is selected at the time of pattern selection. Several patterns are displayed one by one, the display screen is switched until the desired pattern is displayed, and the pattern is selected when the desired pattern is displayed. In this case, the pattern displayed on the display is displayed in the size determined by the pattern data and in the arrangement order determined by the pattern data without performing any processing on the pattern data, and each pattern is surrounded by a rectangular frame. Is displayed.
[0004]
  In the device of Japanese Patent No. 256165, when pattern data of a plurality of patterns is stored in advance in an external recording medium and the pattern number of the pattern to be sewn is input, the pattern data of the embroidery pattern specified by the pattern number Is read from the external recording medium and displayed on the display. In this case as well, only one pattern designated by the size determined by the pattern data is displayed without performing any processing on the pattern data.
[0005]
  As described above, the conventional pattern display device for a sewing apparatus can display only a small number of patterns on the display at the time of pattern selection, and displays the pattern in a size determined by the pattern data. In addition, a technique for deleting and displaying part of the pattern data has not been proposed. Further, when a pattern is not selected for embroidery sewing, accompanying information such as the thread color and the number of colors of the desired pattern and the time required for sewing cannot be displayed on the display.
[0006]
[Problems to be solved by the invention]
  When a user newly purchases an external recording medium that stores a large number of pattern data, there is a request to know the stored patterns, the number of colors in each pattern, the sewing time of each pattern, etc. is there. Or, there are similar requests at exhibitions of new products.
  However, in the conventional pattern display device for a sewing device, it is difficult to display many patterns on the display at the same time because the pattern is displayed in the size determined by the pattern data, and when the pattern is not selected for sewing. Therefore, it is impossible to display additional information such as the thread color, number of colors, sewing time, etc. of the desired pattern on the display, and the pattern data includes data for displaying a square frame surrounding the outside of the pattern, etc. In such a case, since there is no function that can display only the pattern by deleting display data such as unnecessary square frames, there is a problem that a display area per pattern becomes large.
[0007]
  An object of the present invention is to enable a pattern display device for a sewing apparatus to simultaneously display a large number of patterns on a display, and to display accompanying information of a desired pattern regardless of selection of a pattern for sewing. For example, an unnecessary square frame may be deleted from each pattern so that only a net pattern can be displayed.

The ROM 7 a of the ROM card 7 is connected to the bus 22 via the connector 30.
[0028]
  The ROM 24 stores stitch data of a plurality of practical stitches and pattern data of a large number of embroidery patterns that are relatively frequently used. The pattern data of a large number of embroidery patterns is grouped by type of embroidery pattern. Stored. The ROM 7a of the ROM card 7 stores a large number of embroidery pattern data that is relatively infrequently used, and stores a large number of embroidery pattern data grouped according to the type of the embroidery pattern. One of the plurality of ROM cards 7 is inserted into the card slot 8. Many embroidery patterns include various types of characters, figures and shapes, marks, characters-(For example, famous people appearing on TV, movies, etc., animals, robots, etc.).
[0029]
  Regarding the pattern number, the pattern number data is not added to the pattern data of each embroidery pattern, but the pattern numbers are 0, 1, 2,... In order from the first embroidery pattern stored in the ROM 24. After the last pattern number, the pattern numbers are counted in order from the head of the embroidery pattern stored in the ROM 7a. However, all embroidery pattern data may be stored in the ROM 7 a of the ROM card 7 without storing the embroidery pattern data in the ROM 24.
[0030]
  FIG. 3 shows the data structure of the pattern data in the ROM 24. The ROM 24 stores pattern data of a plurality of embroidery patterns, and the pattern number I is 0, 1, 2,. Be counted. The pattern data of each embroidery pattern includes pattern display data for displaying an embroidery pattern, sewing data for embroidery sewing, and accompanying information display data for displaying accompanying information. FIG. 5 shows an example in which 15 embroidery patterns are displayed using the pattern display data. The pattern display data of each embroidery pattern includes data for displaying the embroidery pattern and a square frame surrounding the embroidery pattern. FIG. 7 is an example in which a reduced reduced pattern (panda pattern) and its accompanying information are displayed. As can be seen from this figure, the accompanying information of each embroidery pattern includes a pattern number and a plurality of framed items. The color-specific pattern portions, the thread colors of the color-specific pattern portions, the total number of thread colors, and the sewing time are included. The pattern display data and the accompanying information display data are stored in the form of bitmap data (dot image data). The structure of the pattern data in the ROM 7a is the same as that shown in FIG.
[0031]
  In addition to a general control program for sewing control and display control for sewing practical patterns, the ROM 24 displays a plurality of embroidery patterns stored in the ROMs 24 and 7a on the display 10 while displaying a desired number of embroidery patterns. Pattern selection processing for selecting a pattern, editing processing for performing editing processing such as size setting and position setting on the selected embroidery pattern via the display 10, and embroidery sewing processing for embroidery sewing the selected embroidery pattern A control program for including pattern selection / editing / sewing control, a control program for pattern display control unique to the present application, and the like are input and stored in advance. The RAM 25 is provided with memories (memory such as flags, pointers, counters, registers, buffers, etc.) necessary for the various controls. In the EEPROM 27, mode setting data (flag data) for setting a sequential display mode to be described later is stored in advance.
[0032]
  Here, the pattern display control peculiar to the present application will be briefly described. FIG. 6 shows a matrix of 5 rows and 6 columns on the display 10, for example, 30 reduced patterns obtained by reducing the embroidery pattern at a predetermined magnification under the sequential display mode. Displayed in a matrix (a matrix corresponding to the touch keys of the touch panel 29), and is displayed on the entire screen of the display 10 in order from the earliest pattern number, and the touch key is used to know the accompanying information of the reduced pattern. When the reduced pattern is specified via the button, for example, as shown in FIG. 7, the reduced pattern and its accompanying information are displayed.
[0033]
  Then, after the accompanying information is displayed, the screen of the display 10 returns to the original screen, and when the reduced pattern is designated by the touch key, the next 30 reduced patterns are displayed on the display 10, and so on. The display as described above is executed until the last reduced pattern is displayed, and after the last reduced pattern, the process returns to the first reduced pattern and repeats in the same manner. After the last embroidery pattern in the ROM 24, the process proceeds to the first embroidery pattern in the ROM 7a. In this way, as many reduced patterns as possible are displayed on the display 10 and the accompanying information is displayed for the designated pattern among the displayed patterns, and the display contents are automatically switched sequentially until all the reduced patterns are displayed. It will be.
[0034]
  Next, the pattern display control routine will be described with reference to the flowcharts of FIGS. In the figure, the symbol Si (i = 1, 2,...) Indicates each step. When the power of the embroidery sewing machine M is turned on, this control is started, and it is first determined whether or not the ROM card 7 is connected (attached) (S1). If the determination is No, the normal processing of S3 is performed. (Processing unrelated to this pattern display control) is executed, and this control is also terminated when the normal processing is terminated.
[0035]
  If the determination in S1 is Yes, it is determined whether the mode setting data in the EEPROM 27 is “1” and the display mode is instructed sequentially (S2). If the determination is No, the process proceeds to S3. When the determination in S2 is Yes, the pattern number I counted by the soft counter is set to 0, or initial setting such as virtual detection area setting shown in FIGS. 4 and 6 is executed (S4). Next, the final pattern number Imax (total number of patterns) is calculated by searching the pattern data in the ROMs 24 and 7a and stored in the memory of the RAM 25 (S5).
[0036]
  Next, the pattern display position counter J is initialized to 0 (S6). The pattern display position will be described with reference to FIG. 4. The screen of the display 10 is divided into a matrix of 5 rows and 6 columns, and the pattern display position is set as J = 0, 1, 2,... 30 touch keys of 5 rows and 6 columns correspond to 30 pattern display positions of 5 rows and 6 columns (multiple rows and multiple columns). Next, the pattern display data of the I-th pattern data is read (S7), and then it is determined whether or not the pattern display data includes square frame display data (S8). If the determination is Yes The square frame display data is deleted from the pattern display data (S9), and the process proceeds to S10. If the determination in S8 is No, the process proceeds to S10. In this way, the display data of the square frame is erased in order to display as many patterns as possible on one screen by minimizing the display area of each pattern.
[0037]
  Next, in S10, the pattern display data is converted into reduced pattern display data of a reduced pattern in order to display the embroidery pattern when the pattern display data is displayed without being reduced as a reduced pattern reduced at a predetermined magnification. The data is stored in the display data memory of the RAM 25. Next, a control signal for displaying the reduced pattern at the Jth pattern display position is output to the display controller 34, and the reduced pattern is displayed at the Jth pattern display position (S11). The interval between patterns in FIG. 6 is closer than the interval between patterns when selecting the pattern shown in FIG. 5 (interval between net patterns excluding the square frame surrounding the outside of the pattern).
[0038]
  Next, it is determined whether or not I = Imax (S12). If the determination is No, it is determined whether or not J = 29 (S13). If the determination is No, I and J are each incremented by one. (S14), and then the process returns to S7 and S7 and subsequent steps are repeatedly executed. Therefore, as illustrated in FIG. 6, at the pattern display position of J = 0, 1, 2,. , 1, 2,... 29, a reduced pattern is displayed.
[0039]
  As a result, if the determination in S13 is Yes, a key scan for the touch panel 29 is executed (S15), and it is determined whether any reduced pattern is designated by pressing any touch key (S16). When any one of the reduced patterns is specified, the pattern number K of the specified reduced pattern is calculated based on the key scan signal (S17). Next, the display data of the accompanying information in the pattern data of the Kth pattern is read (S18), and a command to delete a plurality of reduced patterns displayed on the display 10 is output to the display controller 34 (S19). Next, in S20, the Kth reduced pattern and its accompanying information are displayed on the display 10. That is, the Kth reduced pattern is displayed at the pattern display position where J = 0, and the pattern number, the plurality of color-specific pattern portions, the thread color, the number of colors, and the sewing time are displayed at the other pattern display positions. Become.
[0040]
  Next, it is determined whether any key on the operation panel 11 has been operated (S21). If the determination is No, the screen of the display 10 is returned to the previous screen immediately before the key scan (S22), and thereafter Returning to S15, S15 and subsequent steps are repeated. Therefore, it is possible to designate another reduced pattern on the restored previous screen and display the accompanying information, and to designate the reduced pattern and display the accompanying information as many times as desired.
[0041]
  When the reduced pattern is no longer specified on the screen, the determination in S16 is No, the process proceeds to S24, and the time counting process for measuring the duration after the determination in S16 becomes No is executed. Whether or not a predetermined time (for example, 2 seconds) has elapsed (S25). If the determination is No, the process proceeds to S15 and repeats S15 and subsequent steps. If the determination in S25 is Yes, whether I = Imax or not. If it is determined (S26) and I is not equal to Imax (S26: No), the pattern number I is incremented by one in S27, and the process returns to S6, and S6 and subsequent steps are repeated. Since S24 and S25 are provided and the process proceeds to S26 after a predetermined time elapses, the screen of the display 10 is held for the predetermined time, and it becomes possible to designate another reduced pattern on the same screen.
[0042]
  Therefore, the following I = 30,31,..., 59, when 30 reduced patterns are sequentially displayed at the pattern display positions of J = 0, 1, 2,... 29, the determination in S13 is Yes, and S15 and thereafter are the same as described above. After that, 30 reduced patterns are sequentially displayed on the display 10 in the same manner as described above. Every time the screen of the display 10 becomes full, S15 and subsequent steps are repeated as described above. When the final reduced pattern is displayed, the determination in S26 is Yes, the process proceeds to S4, and the process of S4 is repeated. That is, the display as described above is performed from the first reduced pattern. If the determination in S21 is Yes, the process corresponding to the key operated in S23 is executed, and then this control ends. For example, when the “end” key of the operation panel 11 is operated, the pattern display control is ended.
[0043]
  Next, the operation and effect of the pattern display device described above will be described.
  Mode setting data for setting the sequential display mode is stored in the EEPROM 27. In the sequential display mode, the pattern display data among the pattern data of the plurality of embroidery patterns is sequentially read from the ROMs 24 and 7a, and the embroidery pattern is read at a predetermined magnification. Since a plurality of reduced patterns can be displayed on the display 10 in 5 rows and 6 columns, a large number of embroidery patterns can be displayed on the display 10 at the same time, from the first reduced pattern to the final reduced pattern. Since it can be displayed sequentially, it is convenient for confirming a plurality of patterns, and since it is displayed in a reduced pattern, many patterns can be displayed simultaneously. In particular, when a ROM card 7 storing a plurality of patterns is newly purchased, it is convenient for checking those patterns.
[0044]
  Since the display data in the square frame surrounding the outside of the pattern is erased from the pattern display data and converted to reduced pattern data, the display 10 displays only the net reduced pattern without the square frame in 5 rows and 6 columns. Is done. Therefore, more reduced patterns can be displayed on one screen of the display 10 than when a reduced pattern is displayed with a square frame, and the number of screen switching is reduced, which is efficient.
[0045]
  The display 10 has a touch panel 29. The touch panel 29 is provided with, for example, 30 touch keys for individually specifying a plurality of reduced patterns displayed in 5 rows and 6 columns. Of the many reduced patterns, a desired reduced pattern can be specified by specifying the corresponding touch key, and by specifying the desired embroidery pattern with the touch key, accompanying information corresponding to the reduced pattern can be specified. Since (a plurality of color-specific pattern portions, thread colors, the number of colors, sewing time, etc.) can be read out and displayed on the display 10, one or a plurality of desired patterns are sequentially attached via touch key operations. Can know. Moreover, since this pattern display control is independent of the pattern selection control for selecting a pattern for embroidery sewing, one or more desired patterns are selected even when no pattern is selected for embroidery sewing. You can know accompanying information about.
[0046]
  The ROM card 7 is an external recording medium that is detachably connected to the control device 20 of the sewing machine. When a new ROM card 7 storing pattern data of a plurality of patterns is purchased, the pattern display control is performed. It is possible to grasp the whole picture of a plurality of patterns stored in the ROM card 7 via. Since data for setting the sequential display mode is stored in the EEPROM 27 in advance, the sequential display mode is automatically set when the ROM card 7 is mounted on the sewing machine and the sewing machine is turned on. Prior to the selection, an embroidery pattern to be embroidered is determined by viewing a number of reduced patterns sequentially displayed on the display 10, or an embroidery pattern to be embroidered is determined after knowing accompanying information of each embroidery pattern. Convenient to.
[0047]
  Since the sequential display mode is automatically set only when the mode setting data stored in advance in the EEPROM 27 indicates the sequential display mode, the sequential display mode is automatically set via the mode setting data. And the sequential display mode is not automatically set, which increases the degree of design freedom.
  In the above-described embodiment, when the screen is filled with 30 patterns, the screen automatically switches to the next screen (31st to 60th patterns). Then, since the next page key 10a for manual operation unnecessary for such automatic screen switching is deleted from the screen and a pattern is displayed instead, more patterns can be displayed.
[0048]
  Next, a modification example in which the embodiment is partially changed will be described.
1) A mode setting switch connected to the control device 20 is provided in the vicinity of the operation panel 11 of the sewing machine so that the display mode is set sequentially only when the operator turns on the mode setting switch. In this case, the display mode can be sequentially set according to the operator's will only when the operator desires, and the degree of freedom in using the pattern display device is increased.
2) The mode setting data (flag data) for sequentially setting the display mode is stored in the head area of the ROM 7a of the ROM card 7, and the display mode is set sequentially based on the mode setting data. May be.
[0049]
3) Instead of deleting the display data of the square frame from the pattern display data, the display data may be converted into reduced pattern display data and displayed with the square frame.
4) The touch panel 29 of the display 10 may be omitted, and a numeric keypad may be provided on the operation panel 11 so that when a displayed reduced pattern is designated, a number is entered from the numeric keypad.
