Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a contour of a character, such as a brush character, which has a line width and is used for cutting on a surface of a sheet-like member by driving a cutting plotter. Regarding line cutting method.

[Prior Art] Conventionally, a plotter called a cutting plotter is known in which a cutter is rotatably held by a pen carriage that relatively moves in a XY direction on a sheet-shaped member mounted on a recording surface of the plotter. Is.

According to this plotter, the pen carriage is moved over the sheet-shaped member with the blade edge of the cutter held by the pen carriage pressed against the surface of the sheet-shaped member mounted on the recording surface.
By relatively moving in the −Y direction, the surface of the sheet-shaped member can be automatically cut into various shapes.

In the conventional plotter, when a contour line of a character having a line width such as a brush character or a thick Gothic character is cut on the surface of the sheet-shaped member mounted on the recording surface, as shown in FIG. The contour data of 10 is stored in a storage means such as a ROM, a hard disk, a floppy desk, etc. as bag character data of one stroke, and the bag character data of the contour data of the character 10 to be cut is searched from the storage means. On the basis of the bag character data, the pen carriage of the plotter is relatively moved in the XY direction on the sheet-shaped member mounted on the recording surface, and the contour line of the character is displayed on the surface of the sheet-shaped member.
As shown by the solid line in FIG. 2, 12 is cut as a single-stroke bag character.

[Problems to be Solved by the Invention] However, as described above, the contour plot 12 of a character having a line width as shown in FIG. 2 is drawn with a single stroke on the surface of the sheet-like member by driving the cutting plotter. When cut as a bag character, a change point portion (hereinafter referred to as a change point portion) 14 in which the direction of the outline 12 of the character suddenly changes to an acute angle or the like, as shown in FIG. Further, the blade edge of the cutter 20 held by the pen carriage pressed the sheet-shaped member 30 being cut into the inside thereof, and rolled up or distorted the sheet-shaped member 30. Then, the changing point portion 14 of the outline 12 of the character cannot be accurately cut into the desired shape on the surface of the sheet-like member 30, and as shown in FIG. 4, the changing point of the outline 12 of the character is changed. Portion 14 was distorted or distorted unnaturally. This was particularly remarkable when the sheet-shaped member was formed of rubber or the like which was easily deformed.

The present invention has been made in view of such a problem, and is accurate to a target shape without breaking or distorting the change point portion of the outline of a character having a line width such as a brush character and thick Gothic character. It is an object of the present invention to provide a character contour line cutting method (hereinafter, referred to as a character contour line cutting method) using a cutting plotter that can be cut into two.

[Means for Solving the Problems] To achieve the above object, the method for cutting a contour line of a character according to the present invention uses contour line data of a character having a line width, such as a brush character, as a character for each fraction of the character. The contour plotting data of the portion is stored in the storage means as a collection data, and the cutting plotter is driven based on the contour contour data of the character portion for each fraction of the contour contour data of the character stored in the storage means. The contour line of the character portion of each character of each character is sequentially cut on the surface of the sheet-shaped member, and the contour line of the character is cut on the surface of the sheet-shaped member.

[Operation] In the character outline cutting method of the present invention, the character outline data is stored as a collection of outline data of character portions for each stroke of the character, that is, for each stroke of the character. It is stored in the means.

Then, the cutting plotter is driven based on the contour line data of the character portion for each fraction of the storage means that stores the contour line data of the character, and the character portion for each fraction of the character is driven on the surface of the sheet-shaped member. By sequentially cutting the contour lines of, the contour line of a character having a line width on the surface of the sheet-shaped member is cut.

Therefore, a portion where a contour line of a character portion of one stroke of a character intersects with a contour line of another character portion of one stroke of the same character, that is, a change point where the direction of the contour line of the character changes rapidly. In the part, it is not necessary to drastically change the blade edge direction of the cutter gripped by the pen carriage of the cutting plotter so that it can follow the contour line of the character like the contour line of a single-stroked bag character By making the outlines of the character portion of one stroke intersect with each other in an acute angle or the like, the change point portion of the outline of the character can be easily and naturally cut by the blade edge of the cutter gripped by the pen carriage.

Therefore, while cutting the surface of the sheet-shaped member with the blade edge of the cutter gripped by the pen carriage of the cutting plotter, the blade edge of the cutter does not roll up or distort the sheet-shaped member at the changing point of the outline of the character. , The changing point of the outline of the character is accurately cut into the desired shape without collapse or distortion.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a preferred embodiment of character contour line data used in the cutting method of the present invention. More specifically, a cut line when a character contour line is cut on the surface of a sheet-shaped member based on the character contour line data. Is shown. The embodiment in this figure will be described below.

In the figure, 100 indicates a brush character having a line width and a length.

Hereinafter, the contour line data of a character used in the cutting method of the present invention will be described in detail by taking the brush character 100 of this length as an example.

In the outline data of characters used in the cutting method of the present invention,
The contour line data of the brush character 100 is held for each stroke of the character, that is, as the gathered data of the contour line data of the character portion for each stroke of the character. Specifically, the first
As shown in the figure, the outline data of the brush character 100 is
The contour line data of the horizontal bar 102 of one stroke of the character, the contour line data of the vertical bar 104 of one stroke that extends diagonally to the left across the middle portion of the horizontal bar 102 of the character, and the vertical bar 104 of the character. The outline data of the vertical bar 106 of one stroke that extends diagonally to the right across the middle portion and the outline data of a total of three character portions are collected and collected.

The contour line data of the brush character 100, which is a collection of the contour line data of these three character portions, is stored as the contour line data of the length brush character 100 in a storage means such as a ROM, a hard desk, or a floppy desk. There is.

The character outline data shown in FIG. 1 is configured as described above.

Next, the contour plotting data of the brush character 100 stored in the storage means is used to drive the cutting plotter, and the contour line cutting method of the present invention causes the contour of the brush character 100, which is the length of the brush character 100 on the surface of the sheet member. A preferred embodiment of the method of cutting a line will be described.

A sheet-like member made of rubber or the like that is easily deformed is mounted on the recording surface of the cutting plotter. Then, in a state in which the blade edge of the cutter gripped rotatably by the pen carriage of the cutting plotter is pressed against the surface of the sheet-shaped member, based on the contour line data of the above-mentioned length and brush character 100 input to the storage means, the pen carriage X-on the sheet-shaped member
Move relatively in the Y direction. Then, as shown in FIG. 1, a contour line 102a of a horizontal bar character portion corresponding to one stroke of the brush character 100 and a vertical bar character extending diagonally leftward corresponding to one stroke of the brush character 100 of length. Part outline 104a
Then, the contour line 106a of the character portion of the vertical bar 106a extending diagonally to the right, which corresponds to one stroke of the brush character 100, is sequentially cut on the surface of the sheet-shaped member. Then, on the surface of the sheet-shaped member,
A contour line 12 of a brush character called a length, which is a collection of the contour lines 102a, 104a, 106a of the above three character portions, is cut.

According to this cutting method, the changing point portion 14 of the contour line 12 of the brush character 100 where the contour line 102a of the character portion corresponding to the horizontal bar and the contour line 104a of the character portion corresponding to the vertical bar intersect, and the two vertical bars At the change point portion 14 of the contour line 12 of the brush character 100 where the contour lines 104a and 106a of the corresponding character portion intersect, it is not necessary to drastically change the blade edge direction of the cutter grasped by the pen carriage, and the contour of the brush character 100 The change point portion 14 of the line 12 is accurately cut into a desired shape without any collapse or distortion.

In addition, on the surface of the sheet-shaped member 12
When cutting, the contours 102a, 104a, 106a of the character portion corresponding to the one cut may be cut in any order starting from the contour line of any character portion, and the strokes such as the length to be stored in the storage means. By changing the storage order of the contour line data of the character portion for each stroke of the contour data of the character 100, the order can be changed as appropriate.

Further, according to the present invention, a sheet-shaped member is mounted on a flat recording surface having a large area, and the pen carriage is moved on the sheet-shaped member in the X-Y directions to move the surface of the sheet-shaped member to the pen carriage. The pen carriage is moved in the X direction on the sheet-shaped member while moving in the Y-direction on the recording surface which is cut by the cutter gripped on the so-called flat type, or the sheet-shaped member which has a semi-cylindrical shape. Therefore, the present invention can be used for any so-called vertical type cutting plotter in which the surface of the sheet-shaped member is cut by the cutter held by the pen carriage.

Further, it is needless to say that the present invention can be used not only in the case of brush characters but also in the case of cutting the contour lines of various characters having a line width such as thick Gothic characters on the surface of the sheet-shaped member.

[Effects of the Invention] As described above, by using the character contour cutting method of the present invention, the cutting plotter is driven to form brush characters, thick Gothic characters, etc. on the surface of the easily deformable sheet-shaped member such as rubber. If you cut the contour line of a character with a line width with the cutter that is held in the pen carriage of the cutting plotter, when the change point part of the contour line of the character where the direction changes abruptly Accurate to the desired shape with no change or distortion at the changing point of the contour line of the character on the surface of the sheet-shaped member without pressing the sheet-shaped member inward with the blade edge of the cutter and rolling it up or distorting it.
