〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

The data input section 1 is provided when there is basic drawing pattern data including at least one basic pattern data (for example, land, line data, etc.) 61 and editing processing, repeating pattern figures, parallel movement figures, two rotation movements. Editing control data includes functional data selected from editing functions such as figures, 'M symmetric moving figures, etc., and control parameters indicating parameters such as moving direction, moving interval, and number of repetitions for this functional data. Input drawing data.

The data processing section 2 reads the drawing data from the data input section 1, and when this drawing data includes editing control section data, outputs the basic drawing pattern data and editing control data of this drawing data from the first output terminal. The edited drawing pattern data is read from the edited drawing pattern data storage section 9 and outputted to the second output terminal, and when there is no editing control data, this drawing data, that is, the basic drawing pattern data is outputted from the second output terminal. do.

The basic drawing pattern data storage section 5 and the editing control data storage section 6 each store basic drawing pattern data and editing control data from the first output terminal of the data processing section 2.

The processing function storage unit 7 stores a program (hereinafter referred to as an editing processing program) that defines an editing processing algorithm for each editing function.

The data editing section 8 reads the basic drawing pattern data and editing control data from the basic drawing pattern data storage section 5 and the editing control data storage section 6, and stores the editing processing program corresponding to the function data of the editing control data in the processing function storage section. The basic drawing pattern data is edited based on the editing control data, and edited drawing pattern data is output.

The edited drawing pattern data storage section 9 is stored in the data editing section 8.
The edited drawing pattern data from is stored.

The drawing machine control section 3 controls the drawing machine section 4 using output data from the second output end of the data processing section 2, and the drawing machine section 4 is configured to draw a pattern corresponding to the drawing data. .

In this embodiment, an editing control data storage section 6, a basic drawing pattern data storage section 57, an edited drawing pattern data storage section 9. A magnetic disk was used as the processing function storage section 7. In addition, a digital computer was used as the data editing section 8, and a digital computer was also used for the data processing section 2, but these are not physically separate, but operate in multitasking and have logically separate functions. .

Next, the operation of editing processing centered on the data editing section 8 of this embodiment will be explained.

FIG. 2 is a flowchart for explaining the operation of editing processing in this embodiment.

Steps 81 to S5 show the flow of editing processing centered on the data editing section 8, and step S6, indicated by a broken line, shows a section in which an editing processing program for each editing function is registered in advance in the processing function storage section 7.

Regarding the editing process in step S3, FIG. 3 shows, more specifically, the flow of the editing process for repeated figures of the same pattern (hereinafter referred to as repeat process).

Further, a case will be described in which the basic drawing pattern shown in FIG. 4(a) is repeatedly drawn four times through this repeat processing, and the pattern shown in FIG. 4(b) is drawn and edited.

The repeat process is a process in which one figure (basic drawing pattern) is repeated a specified number of times at specified intervals in the X direction or any direction in the X direction.

First, the data editing section 8 reads the editing control data read from the editing control data storage section 6 as function data indicating what kind of editing processing is to be performed, and calls a program for repeat processing (S2 and S3). , data indicating the repetition direction minus y, data indicating the repetition interval, and data (3) indicating the number of repetitions are read from the control parameters dependent on this functional data (S31).

Next, each basic pattern data is read from the basic drawing pattern data read out from the basic drawing pattern data storage section 6 and to be subjected to editing processing.

In FIG. 4(a), pad 10. Lines 11-14
．． Each pad 15 is a basic pattern, and these form a set of basic drawing patterns.

Pad 10. The pad 15 has center coordinates (Xi,
'/1) and (x6, 376). Lines 11 to 14 are expressed by the coordinates of the start and end points of the lines. For example, the starting point coordinates of line 11 are (X1+5't) and the ending point coordinates are (X2, V2), and the starting point coordinates of line 14 are (X41 V4) and the ending point coordinates are (X5.3
+'5).

In step S32, the aperture data of the pad 10 is first copied.

Next, from the center coordinates (Xl, y+) of the pad 10, the repetition interval, and the current number of repetitions out of the total number of repetitions, the first repetition position (at,
bi).

Next, a process is performed to determine whether the repeated coordinates (at, b,) are within the maximum coordinate value 17 and minimum coordinate value 16 of the drawing tolerance range (833), and if not, the process is stopped as a data error. (S36).

If the repetition coordinates (at, bt) are within the drawing tolerance range, then a determination process is performed to determine whether the basic drawing pattern has been completed (SS4).

In this case, since the end of the basic drawing pattern is pad 15, the process returns to repeat processing and the aperture of line 11 is
Data and starting point/end point data (Xl, Vt) ・(
X2, 5'2) is read and the same processing as in the case of pad 10 is performed.

Lines 12-14. The same process is repeated for the pad 15 to complete the first repeat process.

Since two repetitions remain, the process for determining the number of repetitions (S35) continues the process for the second repetition.

Finally, the aperture of the pad 15c in FIG. 4(b) is copied from the pad 15, and the coordinate position of the pad 15C (
e6, f6) and edit the data, thereby completing the repeat process.

Next, the data edited by the repeat process is transferred to the edited drawing pattern data storage section 9 (S4). The transferred edited drawing pattern data is accumulated in the edited drawing pattern data storage section 9 until all the basic drawing pattern data is taken into the data editing section 8 and edited.
Thereafter, the data are transferred to the data processing section 2 all together.

〔Effect of the invention〕

As explained above, the present invention has a configuration in which the drawing data includes basic drawing pattern data and editing control data, and has a function of editing the basic drawing pattern data based on this editing control data. Even if the drawing pattern has many repetitions, it is possible to shorten the data creation time and the drawing time without requiring equipment such as a CAD system.
