Description

Description: TECHNICAL FIELD The present invention relates to a brushstroke drawing device provided with a drawing layout device.

(Problems to be Solved by the Prior Art and the Invention) In the case of an envelope or a certificate, a dedicated layout pattern is stored in the layout information storage means in accordance with a difference in paper size, the number of drawing lines, and the like. . (The use of one layout pattern is limited to one type of paper size.) Therefore, the number of layout information increases, and selection of desired layout information becomes complicated, and the used memory capacity increases. And so on.

Also, there is a limit to the number of paper sizes that can be stored in advance, so when drawing characters on paper that does not match the dimensions, you must select layout information with closer dimensions, and There was a disadvantage that the arrangement balance was lost.

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

However, satisfactory results could not be obtained due to the variety of sizes of the paper.

Therefore, it is conceivable to increase the number of types of sizes that can be specified. However, since the operation of selecting the size increases accordingly, and the paper sizes that can be selected must be stepwise, the specified size and the actual paper size are required. If the sizes are different, there is a problem that the overall character arrangement balance of the finished writing is slightly shifted.

In the case of a paper sheet, since the drawing range is limited to the vicinity of the center in the horizontal direction of the paper, the character size, position, and the like need only be enlarged or reduced based on the ratio of the paper vertical dimension.

However, since envelopes and commendation certificates have a wider drawing range and have fixed areas such as postal codes, they cannot be processed using the same uniform calculation method as for paper, and appropriate measures have been desired.

(Means for Solving the Problems) According to the present invention, there is provided a holding unit for holding a writing brush based on data such as characters and symbols stored in drawing data storage means.
The number of character columns corresponding to a plurality of layout patterns, the maximum number of characters in each column in a brush drawing device that draws a brush by moving each pulse motor of the X, Y, Z axes in the X, Y, Z axis directions Layout information storage means for storing layout data such as drawing position, character size, character spacing, etc., and a paper type selection and a layout selection corresponding to the selected paper type. A layout pattern selecting unit, and a layout information correcting unit for correcting layout information of the selected layout, based on a comparison result between a given actual paper size and a reference size stored in the layout information storage unit and a type of paper. The above problem can be solved by a brushstroke drawing device including a drawing layout device, which is provided with a layout information calculation unit that calculates and corrects layout information.

(Embodiment) The control block diagram of FIG. 1 will be described. When desired drawing data is selected by the data input and operation instructing means f, the drawing control means e reads out the corresponding drawing data from the drawing data storage means g, and sets the paper type and the layout pattern suitable for the use to the paper type and the layout pattern. The selection by the layout pattern selection means b causes the drawing control means e to pass the paper type and layout pattern information and the actual paper size information obtained from the paper length and width size detection means c to the layout information calculation means d. d reads layout information matching the received paper type and layout pattern from the layout information storage means a, enlarges or reduces the layout information according to the ratio between the actual paper size and the reference size, and the paper type, and controls the drawing of the result. Returning to the means e, the drawing control means e is a data input, operation instructing means Waiting for the start of drawing is indicated by the final layout information and control driving the drawing data unit h
The drive control unit h issues a command to the drive device i based on the received information, and moves and draws the brush-type brush k held in the brush-holding unit j.

The lateral dimensions are as follows. First, the sheet is fed in the left-right direction until the left sheet sensor outputs a level at which no sheet is present (normally, when the sheet is set, the left and right sensors are in the state of the sheet). The sheet is driven one step at a time to move the sheet to the left.

This is performed 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 (a), the number of steps × (paper moving length per pulse motor step) + distance between left and right paper sensors (L) = paper lateral dimension (La + L + Lb).

ST8 When an instruction is issued, the drawing is performed based on the drawing data registered at the size and position specified by the layout information. After completion, return to ST1.

FIG. 4A and FIG. 4B illustrate the measurement of the width and height of the paper.

The input of the drawing data has been completed before the paper is set, and the paper is set at an appropriate position in the grit roller 100 and the guide rollers 101 and 102 as shown in FIG. Paper guide 104
Contact the paper).

Next, the paper guide 105 is manually brought into contact with the paper to measure the vertical width with the paper guide interlocking volume 2.

Press the start button and the edge Ea of the paper will be the sensor 4
Is detected, and the sheet is moved in the reverse direction, and the edge Eb of the sheet is detected by the sensor 5 to obtain Lb.

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

When the vertical and horizontal dimensions of the paper are determined, the standard layout pattern shown in FIG. 5 is selected from the plurality of standard layout patterns, and the layout dimensions of the paper layout pattern to be drawn from now on are calculated.

Since the vertical width of the paper has been measured, the drawing position, start position, end position, character size, and character spacing, which are the main determinants of the layout pattern to be drawn, will be calculated.

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

FIG. 8 defines the standard layout data and the paper layout data to be used for the drawing position, character size, character spacing, start position, end position, character center of the first character, and character center of the last character. Is calculated based on the layout data.

Calculation method The horizontal ratio and vertical ratio 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 = p1 × ra P2 = p2 × ra SP1 = sp1 × rb SP2 = sp2 × rb The character size is as follows when the following function is defined.

min (ra, rb) Select the smaller of ra and rb.

SC1 = sc1 × min (ra, rb) SC2 = sc2 × min (ra, rb) Only the first column is shown. (The same applies to the second column.) C11 = st1-sc1 / 2 C1m = en1 + sc1 / 2 C11 = s11 x rb C1m = clm x rb ST1 = C11 + SC1 / 2 EN1 = Clm-SC1 / 2 ST1 = ｛st1- sc1 / 2｝ × rb + sc1 × min (ra, rb) / 2 EN1 = ｛en1 + sc1 / 2｝ × rb + sc1 × min (ra, rb) / 2 If ra ≧ tb, ST1 = st1 × rb EN1 = en1 × rb ra < If tb, ST1 = (st1-sc1 / 2) x rb + sc1 x ra / 2 EN1 = (en1 x sc1 / 2) x rb-sc1 x ra / 2 However, the length of the paper to be drawn on the standard layout pattern If the ratio of the horizontal dimensions is not well-balanced, the character spacing becomes large and it is difficult to see. In that case, the correction is made by including a correction value for correcting the character spacing.

(Effect) Since only 19 types of reference layout patterns, including 6 types of reference layout patterns for paper sheets, 12 types of reference layout patterns for envelopes, and 1 type of commendation certificate, can be used to create a layout pattern in a stepless manner, the selection operation is complicated. And memory capacity can be reduced.

The actual size of the sheet is detected and given, and enlargement or reduction is performed according to the use according to the type of the sheet, so that the balance of the overall character arrangement of the finished writing is improved.
That is, even if the size and type of the paper are changed, the layout of characters and symbols is automatically determined, and stable quality is obtained.

 Further, the paper size selection operation is not required.
