Abstract

PURPOSE:To prevent the collapse of characters at the time when a brush-nose shape is thick and the scantiness of characters at the time when the brush-nose shape is thin by selecting a code value on the brush drawing device side in conformity with a level value displaying the size of the brush nose section incorporated into a writing brush type pen. CONSTITUTION:Movement magnification KZ in the direction Z to a reference value is determined by the size of characters drawn and code values while using reference magnification proper to the size of characters drawn and being multiplied to the movement in the direction Z of drawing data as a reference value. The movement magnification KZ is specified by selecting the code value, and the level value of a writing brush type pen previously determined by measurement and the code value are collated, thus allowing the drawing of characters composed of the number of strokes having standard size. When the code value is selected, another code value is selected without conforming the level value of the writing brush type pen previously determined by measurement and the code value, thus drawing the number of strokes constituting characters drawn thickly or thinly in response to preference, the object of usage, etc.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush-drawing device capable of drawing a brush-written character, and more particularly to a brush-drawing device capable of correcting the thickness of a drawn character.

[0002]

2. Description of the Related Art A writing brush drawing device controls the thickness of characters and the like by continuously driving and controlling a writing pen in the Z direction perpendicular to the drawing paper surface based on drawing data, and at the same time, controlling the writing pen and drawing paper. Is a type of plotter that draws brush characters and the like on the drawing paper by relatively controlling the movement in the X and Y directions parallel to the drawing paper surface and orthogonal to each other.

That is, the writing brush drawing device changes a pen into a writing brush in contrast to a well-known pen plotter, and the pen of the pen plotter is light in the non-contact position on drawing paper (hereinafter simply paper) and the paper. 2 with the contact position to contact with the writing pressure
In contrast to switching control between positions, the brush drawing device controls the thickness of characters by continuously moving the brush up and down with respect to the paper in a contact state between the brush and the paper. This is a plotter that draws a handwriting-like brush character on the paper by controlling the movement of the brush and the paper to a non-contact position in the portion where the stroke is not drawn.

The shape of the tip of the writing pen used in the writing device is not uniform because it varies in shape, including the thickness, even within the same lot, but conventionally the difference in the shape of the tip of the writing pen was ignored. Therefore, it has been assumed that all brush pens are uniform. As a result, there have conventionally been the following problems.

That is, (1) when the brush pen is exchanged, the difference in the thickness of the tip shape causes a difference in the character quality, especially the character thickness, and the drawn character quality is not constant.

(2) When the center of variation in the shape of the tip of the writing pen differs greatly between lots, and even in the same lot, the writing brush has an abnormally sharp tip shape such as an extremely thick or thin tip or a curved shape. When the pen is mixed in the product, the created drawing data may not be usable due to the character quality.

(3) It is technically difficult to make a tip-shaped brush pen with a uniform center of variation and a similar level of variation. Since it is necessary to select those of stable quality, it takes time to select, and defective products are eliminated, so that the cost of the writing pen becomes high in terms of man-hours and yield.

(4) The thickness of the drawn character is determined by the thickness of the tip of the writing pen, etc., and the user cannot freely select the character quality of the drawn character. There was such a problem.

[0009]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to solve the conventional problems associated with the writing pen used in the above-described writing brush drawing apparatus.

[0010]

In order to solve the above-mentioned problems, the present invention provides, in a brush drawing apparatus, a reference value that is specific to the size of a character to be drawn and is multiplied by the amount of movement of drawing data in the Z direction. As the moving ratio K in the Z direction with respect to the reference value depending on the size of the character to be drawn and the code value.
Z is determined, the moving magnification KZ is specified by selecting a code value, and the standard value of the standard thickness is obtained by matching the level value of the writing pen determined in advance with the code value. The present invention provides a brush-drawing device having a character thickness correction function configured to enable drawing of characters composed of strokes, and further, in selecting a code value, the level of a writing pen determined in advance by measurement. A brush drawing device having a character thickness correction function configured so that a stroke forming a character can be drawn thick or thin by selecting another code value without adjusting the value and the code value. Is provided.

[0011]

According to the brush-drawing device of the present invention, firstly, by selecting the code value on the side of the brush-drawing device according to the level value indicating the thickness of the tip of the brush pen, the stroke Since the thickness of can draw characters of standard character quality,
With respect to character quality, there is an effect of improving the character collapse when the tip shape is thick and the poor character when the tip shape is thin.

Secondly, by selecting a different code without matching the code value on the side of the writing brush drawing device with the level value of the writing pen, the same writing pen can be used to freely select thick characters or thick characters according to the taste or purpose of use. It has the effect of drawing with thin characters.

Thirdly, since the drawing data may be created with a standard writing pen as a target, there is an effect that the correction work at the time of creating the drawing data is reduced.

Fourthly, since the shape of the tip of the brush deviates from the standard thickness in the past and the character thickness is not standard in the drawing test, it is now possible to use a writing pen. There is an effect that the cost can be reduced.

Fifth, since the shape of the tip of the brush pen is measured in advance, a standard writing quality cannot be obtained by using any of a plurality of code values for adjusting the character thickness. The pen can be checked, and the defective writing pen can be removed when the writing device is shipped.

[0016]

【Example】

(1) Configuration of Brush Drawing Device The configuration of the brush drawing device of the present invention is, for example, the same as that of the brush drawing device described in Japanese Patent Application No. 3-225140 filed by the same applicant as the present invention. Is shown, the configuration is as follows. "If the directions of the respective controls are parallel to the drawing paper (hereinafter, paper) and are orthogonal to each other in the X and Y directions, and the direction orthogonal to the paper mounting surface is the Z direction, the movement of the paper in the X direction , A Y carriage controlled to move in the Y direction and a Z carriage controlled to move in the Y direction together with the Y carriage and continuously controlled to move in the Z direction.
Based on the drawing data, the X-direction, the Y-direction, and the Z-direction are controlled to draw a brush character or the like on the paper ".

(2) Measurement of Writing Pen As an example, a computer and a laser length measuring device are used to measure the shape of the tip of the writing pen for a writing device, and the measurement results are classified into thickness groups. As for the measurement position of the diameter of the tip of the brush pen, the diameter at the position of Ln (n = 1 to 11) from the tip of the tip is measured as shown in FIG.

To measure the diameter of each position of the tip, the brush pen is held vertically with the tip down and moved up and down by a pulse motor to move and position each position of the brush pen to the measurement position. Each position is rotated by an angle of 15 degrees by a pulse motor different from the one described above, and the diameter at that position is measured at 12 positions corresponding to a half circumference.

Table 1 shown below is a hard copy of the measurement data stored in the magnetic disk by the measurement. In Table 1 shown below, the magnification of D at line number 00001, 000.
02 is the level of D, 0000 3 is the maximum standard deviation, and 00
Reference numeral 004 shows the length of the brush portion and line number 00005 shows the thickness of the root.

In line numbers 00007 to 00009, data for the measurement position L1 is shown, and line number 00
The average value of the diameters and the standard deviation of the measured values of the diameters are shown in 007, and the measurement position L is shown in the row numbers 00008 and 00009
The measurement values of the 12 diameters in 1 are shown below. Similarly, the average value of the diameters and the standard deviation of the measurement values of the diameters for the positions from L2 to L11, and the measurement of the 12 diameters at each measurement position are also shown. Values are shown.

[Table 1]

The thickness magnification D in this case is a value relating to the thickness of the brush, which is obtained by calculation by weighting the measurement data of the diameter of each part of the tip part closer to the tip of the tip part. From this value, the brush standard value (D level) is obtained.

The result of arithmetic processing of the measurement data is displayed on the display as shown in FIG. As shown in the figure, the display content is a standard for the measured value of the magnification of D, which is the magnification of the thickness, the level value (brush number) indicating the thickness group, and the diameter of 12 points at each position of the tip part. It is a graph of the maximum value of the deviations (hereinafter referred to as the maximum standard deviation) and the relationship between each measurement position of the tip portion and the average value of the diameters of the measurement positions.

A level value (writing number) is attached to the writing pen which is the object of measurement for the convenience of drawing by the writing apparatus. If the maximum standard deviation is larger than a predetermined value, it is considered that the tip portion is bent or the shape of the tip is abnormal. The thickness magnification D in this case is
It is a value related to the thickness of the brush, which is obtained by performing a weighting on the measurement data of the diameter of each part of the tip part closer to the tip of the tip part, and from this value, the level value of the brush (D
Level) is required.

FIG. 4 shows an example in which the brush pens are classified according to the thickness standard values based on the measurement results. In the figure, the larger the level of thickness, the thinner the tip shape of the brush pen. As a result of measuring 42 writing brush pens and grouping them according to the thickness level, the writing brush pens of the same lot have thickness levels ranging from 2 to 8. It can be seen that the quality of the sano is not constant.

Conventionally, when drawing is performed by randomly using a writing pen of a lot as shown in FIG. 4, the code value that can be selected by the writing device is fixed to one, which corresponds to the code value 5 in FIG. So, for example, if you use a thick brush with a standard value of 2, the drawn characters are too thick and the details are crushed. On the contrary, if you use a fine brush with a standard value of 8,
There was a problem that the letters were too thin and poor.

In the present embodiment, it is possible to prevent the details of the character from being crushed or becoming poor as described above.
That is, as shown in FIG. 1, the brush drawing apparatus according to the present embodiment uses the reference magnification that is specific to the size of the character to be drawn and is multiplied by the amount of movement of the drawing data in the Z direction as the reference value and the size of the character to be drawn. The movement value KZ in the Z direction with respect to the reference value is determined by the code value, the movement magnification KZ is specified by selecting the code value, and the level value of the writing pen determined in advance by the measurement and the code. Characters consisting of strokes of standard thickness can be drawn by matching with the values.

Further, in selecting the code value, by selecting another code value without matching the level value of the writing pen determined in advance with the above-mentioned code value, the strokes constituting the characters to be drawn, It is possible to draw thicker or thinner depending on the taste and purpose of use.

The moving magnification KZ with respect to the reference value for each code value in the size of each character in FIG. 1 is determined by performing a drawing test using a writing pen of each standard value.

(3) Drawing Example FIGS. 5 (A), (B), (C), and (D) are drawn in this order with a thick brush with code values 3, 5, 7, and 9, respectively. The smaller the value is, the standard font thickness.

FIGS. 6A, 6B, 6C and 6D are as follows.
In this order, the strokes are code values 3, 5, 7,
In FIG. 6, the standard character thickness is in the vicinity of FIG. 6 (B) where the code value is 5.

7 (A), (B), (C) and (D),
In this order, write fine brushes with code values of 3, 5, 7,
The standard character thickness is shown in FIG. 7D in which the code value is 9 in FIG. 7D.

As described above, according to this embodiment, the moving magnification KZ with respect to the reference value is designated by selecting the code value, and the standard value of the writing pen determined by the measurement in advance is matched with the code value. You can draw characters consisting of strokes of standard thickness.

Further, in selecting the code value, by selecting another code value without matching the level value of the writing pen determined in advance with the above-mentioned code value, a stroke forming a character to be drawn can be obtained. It is possible to draw thicker or thinner depending on the taste and purpose of use.

[0034]

As described above, according to the writing brush drawing apparatus of the present invention, first, the code value on the writing brush drawing apparatus side is selected according to the level value indicating the thickness of the tip portion attached to the writing pen. As a result, it is possible to draw characters of standard character quality with a stroke thickness.Therefore, with regard to character quality, it is possible to improve the character collapse when the tip shape is thick and the poor character when the tip shape is thin. can get.

Secondly, by selecting a different code without matching the code value on the side of the writing brush drawing device with the level value of the writing pen, the same writing pen can be used to freely select thick characters or thick characters according to the preference or purpose of use. The effect is that it can be drawn with thin characters.

Thirdly, since the drawing data may be created by using a standard writing pen as a target, it is possible to obtain an effect that the correction work at the time of creating the drawing data is reduced.

Fourthly, since the shape of the tip is out of the standard thickness in the past, and the writing pen is not usable because the character thickness is out of the standard in the drawing test, it is possible to use a writing pen per yield pen. The effect that the cost can be reduced can be obtained.

Fifth, since the shape of the tip of the writing pen is measured in advance, a standard writing quality cannot be obtained by using any of a plurality of code values for adjusting the character thickness. It is possible to check the pen, and it is possible to remove defective products of the writing pen when the writing device is shipped.
