Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application) The present invention relates to a method for determining a layout pattern in a brush plotter.

(Prior art and problem to be solved by the invention) In the case of envelope 1 certificate, dedicated layout patterns were stored in the layout information storage means depending on the paper size, number of drawn lines, etc. . (Use of one layout pattern was limited to one type of paper size.) As a result, the number of layout information increases, making selection of desired layout information complicated and increasing memory capacity. There were other problems.

In addition, there is a limit to the number of paper sizes that can be stored in advance, so if you draw characters on paper whose dimensions do not match, you will have to select layout information with a closer size, which will affect the overall character size. There was a drawback that the placement balance was disrupted.

In the case of noshigami, the format is relatively standardized, so
Layout information is enlarged or reduced in accordance with several sizes that can be specified by the operator, based on a standard size.

However, because there are many types of wrapping paper, satisfactory results were not obtained.

Therefore, it is possible to increase the number of sizes that can be specified, but this would increase the amount of time and effort required to select the size.
In addition, the paper sizes that can be selected must be graded, so if the specified size and the actual paper size differ,
There were problems such as the overall character placement balance in the finished writing being slightly off.

In the case of paper, the drawing range is limited to the vicinity of the center in the horizontal direction of the paper, so it is sufficient to enlarge or reduce the font size, position, etc. based on the ratio of the vertical dimension of the paper.

However, since the drawing range for envelopes, such as certificates of commendation, is wide and there are fixed areas such as postal codes, it cannot be processed using the same uniform calculation method as for paper wrapping paper, and an appropriate countermeasure has been desired.

(Means for Solving the Problem) Several types of standard layout patterns are stored in the layout information storage means, each based on frequently used medium-sized sheets such as paper, envelopes, and certificates of commendation. When the operator selects a paper layout pattern suitable for the purpose from among wrapping paper, envelopes, certificates, etc. using the layout pattern indicating means, the actual paper size is automatically recognized by the paper length and width size detection means. death,
A device equipped with layout information calculation means that reads layout information corresponding to the selected paper and layout pattern and enlarges or reduces the layout information according to the ratio between the detected actual paper size and the reference size and the type of paper. It is.

(Example) The control block diagram in FIG. 1 will be explained.

When desired drawing data is selected by the data input and operation instruction means f, the drawing control means e controls the drawing data storage means g.
By reading out the corresponding drawing data from , and selecting the paper type and layout pattern suitable for the purpose using the paper type and layout pattern selection means, the drawing control means e reads the paper type, layout pattern information, and paper length and width size. The practical paper size information obtained from the detection means C is passed to the layout information calculation means d, and the layout information calculation means d reads out the layout information matching the received paper type and layout pattern from the layout information storage means a, and calculates the practical size. The layout information is enlarged or reduced according to the ratio between the paper size and the reference dimension and the paper type, and the results are returned to the drawing control means e, and the drawing control means e is instructed to start drawing by the data input and operation instruction means f. Wait for and drive the final layout information and drawing data #
Based on the received information, the drive control means issues a command to the drive device i to move the brush k held in the brush holder j to draw. There is.

The vertical dimension of the paper can be immediately extracted from the read value by creating a data table of the relationship between the digital output value of the volume and the actual dimension in advance.

For the horizontal dimension, first feed the paper in the left and right direction until the left paper sensor outputs the no-paper level (normally, when paper is set, the left and right sensors are in the state of paper present), then the pulse motor is turned on. The paper is moved to the left by driving one step at a time.

This is done while counting the number of steps until the right paper sensor outputs a level with no paper.

If the right paper sensor runs out of paper, as shown in Figure 4 (a), the number of steps x (paper movement length per one step of the pulse motor) + distance between the left and right paper sensors (L): paper horizontal dimension (La+L+Lb).

4-(a) and 4-(b), the measurement of the horizontal width and vertical width of the paper will be explained.

The input of the drawing data has been completed before setting the paper, and the paper is set at an appropriate position between the grid roller 100 and guide rollers 101 and 102 as shown in FIG. 4-(a). (Set the paper on top of the sensor 4.5 and bring the paper into contact with the paper guide 104).

Next, by manually bringing the paper guide 105 into contact with the paper, the paper guide interlocking volume 2 measures the vertical width.

When you press the start button, the edge Ea of the paper is detected by sensor 4.
Then, the paper is moved in the opposite direction and the edge Eb of the paper is detected by the sensor 5 to find Lb.

La+Lb+L=The width dimension of the paper is determined (L is a fixed dimension).

Once the vertical and horizontal dimensions of the paper are determined, the standard layout pattern shown in FIG. 5 is selected from among the plurality of standard layout patterns, and the layout dimensions of each layout pattern of the paper layout pattern FIG. 6 on which drawing is to be performed are calculated.

Since the vertical width dimension of the paper has been measured, let's calculate the main determining factors of the layout pattern to be drawn, which are the drawing position, start position, end position, character size, and character spacing.

Before calculation, FIG. 7 shows the horizontal and vertical sizes of the standard paper and the horizontal and vertical sizes of the paper to be used.

Figure 8 shows the drawing position, character size, character spacing, starting position,
The end position, the character center of the first character, and the character center of the last character are defined with respect to standard layout data and layout data of the paper to be used, and calculations are performed based on each layout data.

Calculation method The width and height ratios of the paper are as follows.

ra=A/a (horizontal ratio) rb=B/b (vertical ratio) The drawing position and character spacing are as follows.

P1=plXra P2=p2XraSPI=
spl X rb SF3 = sp2 X r
b The character size is determined by defining the following function:

5in (ra, rb) Select the smaller of ra and rb.

SC1=sclXmin(ra, rb)SC2=sc2
Only the first column of xmin(ra, rb) is shown. (Same for 2nd row) CIL=stl-scl/2 C1m=enl+sc
l/2C11=cL1xrb C1m=cl++X
rbST1=C11+SC1/2 EN1=C1m-3CL/2 To summarize the above, 5T1-(stl-scl/2) Xrb+sclXm
in(ra, rb)/2ENI = (enl + s
cl/2) X rb + scl X akin(r
a, rb)/2ra≧rb then 5T1=stlXrb ENI=enl X rb If ra<rb then 5T1=(stl-scL/2)xrb+5clXra
/2ENI = (enl + scl/2) x r
b -scl x ra/However, if the ratio of the vertical and horizontal dimensions of the paper you are trying to draw on is unbalanced with respect to the standard layout pattern, the character spacing will become large and unsightly, so in that case, correct the character spacing. A correction value is also included for correction.

(Effects) Layout patterns can be created steplessly with only 19 standard layout patterns, including 6 standard layout patterns for wrapping paper, 12 standard layout patterns for envelopes, and 1 standard layout pattern for certificates, making selection operations less complicated. It also reduces memory capacity.

Since the actual size of the paper is detected and the paper is enlarged or reduced according to the type of paper, the overall character arrangement balance is improved.

(The quality is stable regardless of the size and type of paper.) Also, there is no need to perform a paper size selection operation.
