Abstract

PURPOSE: To print braille in a desired size at a desired position by generating print data of a predetermined block copy based on the parameters of braille data described by braille code and the size and the position of the points of the braille data and outputting black braille block copy to an output unit. CONSTITUTION: A parameter, braille data and print data files 2, 1, 4 are opened, and the parameter is checked. Then, a heat printing position is set, and the print data made of a header, a basic command and data for a predetermined block copy is generated based on the braille data and the parameter. The data is generated and processed by reading the braille data of one character from a braille data file 1, matching the braille command of the braille data to the braille command stored in a braille code table 6, and calculating the coordinates of the points of the braille data. Then, whether the values of X- and Y- coordinates are disposed at the position exceeding the printing range of the copy or not is checked. If it does not exceed, a black block copy is output to the output unit 5 of a printer, etc.

In that case, it would be very convenient if the converted Braille data could be handled in the same manner as ordinary character data. For example, an output machine such as a printer or an image setter is connected to a general computer, but if a black braille block copy can be output from such an output machine, the braille data can be effectively used and an existing printer such as a printer can be used. Hardware can also be enabled. Further, at that time, if the Braille can be printed in a desired size and at a desired position as in the case of normal character data, the print quality of the black Braille can be improved.

In the case of outputting black braille using a conventional computer, the braille is constructed in the same manner as a normal character font, and the braille is output by a printer or the like. That is,
The braille font used in the conventional braille output is formed by arranging fixed points having a fixed size in a predetermined range at regular intervals, like a normal character font.

The print data generated by the control unit 3 is
It is stored in the print data file 4. The output unit 5 includes a typesetting machine, a printer, an image setter, and the like, and outputs black-and-white Braille to the block copy based on the print data stored in the print data file 4.

Further, in FIG. 1, reference numeral 6 is a Braille code table in which a list of Braille codes is stored in advance.

Next, the operation of the Braille block printing output system thus configured will be described. FIG. 6 is a flow chart showing a schematic operation of the Braille block output system. First,
The parameter file 2 is opened (step 601) and it is confirmed that the file open processing has succeeded (step 602). If the open process of the parameter file 2 fails, an error message is displayed (step 614) and the process ends.

Next, the Braille data file 1 is opened (step 603), and it is confirmed that the file open processing has succeeded (step 604). If the open process of the Braille data file 1 fails, an error message is displayed (step 614) and the process ends. Further, the print data file 4 is opened (step 60
5) Confirm that the file open processing has succeeded (step 606). Here, print data file 4
If the open process of 1 fails, an error message is displayed (step 614) and the process ends.

The parameter data stored in the parameter file 2 is checked (step 607) and it is confirmed whether or not there is an error in the parameter data (step 608). The check items include, for example, whether the parameter value is omitted, alphanumeric characters are not set in the place where the numerical value should be set, and the specified numerical value is not a negative value. If there is an error in the parameter data, an error message is displayed (step 614) and the process ends.

Next, the leading print position is set (step 609). Then, based on the Braille data and the parameter data, Braille print data for a predetermined block copy is generated (steps 610 to 612). In generating the print data, first, the header part is generated (step 610), and then the basic command part is generated (step 6).
11), and the data part is generated (step 61).
2). Then close all files (step 61
3), the process ends.

Next, the process of generating the data portion in step 612 will be described with reference to the flowchart of FIG. First, the Braille data for one character is read from the Braille data file 1 (step 701), and it is confirmed whether this data is data indicating the end of the file (step 702).

If the data does not indicate the end of the file, it is confirmed whether the read Braille data is a line feed mark (step 703). If it is not a line feed mark, the braille code of the read braille data and the braille code table 6
Matching with the braille code stored in (step 704). If there is a match, the coordinate value of each point of the read Braille data is calculated (step 705).

That is, the coordinate values of the points shown in FIG. 4 are calculated. More specifically, first, the coordinates of the points are obtained. Furthermore, the parameter (c) based on the coordinates,
The coordinates of the required points are calculated using the values specified in (d). In the case of the next braille cell (the braille cell on the right of FIG. 4), the coordinates of the point of the next braille cell are calculated based on the value specified by the parameter (e) and the coordinates of the point of the previous cell. From there, the coordinates of the required points are calculated using the values specified by the parameters (c) and (d).

After that, it is checked whether the value of the X coordinate among these coordinate values does not exceed the printing range of the block copy (step 706). If not, the next one character from the braille data file 1 is checked. Braille data for minutes is read (step 707), and the above processing is performed.

In step 704, if the braille code of the read braille data and the braille code stored in the braille code table 6 cannot be matched, it is determined whether the braille code of the read braille data is a page break. Confirmation is performed (step 708), and if the page is not a page break, an error message is displayed and the process ends. If it is a page break, a page break process is performed (step 7
09), and returns to step 706. Also, step 706.
In the case where the value of the X coordinate exceeds the printing range of the block copy, an error message is displayed and the process ends.

On the other hand, in step 703, when the read braille data is a line feed mark, first, from the value specified by the point parameter (f) and the coordinates of the point of the first cell of the preceding line, the braille cell of the next line is determined. The coordinates of the point are calculated (step 710). From there, the necessary points or the coordinates of the points are calculated using the values designated by the parameters (c) and (d) (step 711).

After that, it is checked whether the value of the Y coordinate among these coordinate values does not exceed the printing range of the block copy (step 712). If not, the next character from the braille data file 1 is checked. Braille data for minutes is read (step 707), and the above processing is performed. On the other hand, if the value of the Y coordinate exceeds the printing range of the block copy, an error message is displayed and the process ends.

Therefore, in the Braille block copy output system of this embodiment, the black Braille block copy can be output from the output unit 5 such as a printer or an image setter. Further, at that time, the Braille can be printed at a desired position in a desired size by setting the parameter data shown in FIG. 3 to a predetermined value. Furthermore, by performing various checks, it is possible to reliably print black-and-white Braille.

Next, an embodiment in which the output unit 5 is composed of a Postscript type printer, an image setter, etc. will be described. FIG. 8 shows the parameter data stored in the parameter file 2 in that case. The parameter data shown in FIG.
Although (i) is the same as that shown in FIG. 3, the difference is that the output method can be specified in the parameter data (j) and the way of drawing points can be specified in the parameter data (k). Also, unlike the case of FIG. 5, the parameters (h) and (i) are the head print positions of the X and Y coordinates in the print range as shown in FIG.

For example, as the output method, either output only to a file or output to a printer can be designated. In addition, you can specify whether to draw dots by using a font or a circle.

FIG. 10 is a flow chart showing the schematic operation of the braille block output system in this embodiment. First, open the parameter file 2 (step 100
1) Confirm that the file open processing has succeeded (step 1002). If the open process of the parameter file 2 fails, an error message is displayed (step 1014) and the process ends.

Next, the Braille data file 1 is opened (step 1003), and it is confirmed that the file open processing has succeeded (step 1004). If the open process of the Braille data file 1 fails, an error message is displayed (step 1014) and the process ends. Further, the print data file 4 is opened (step 1005), and it is confirmed that the file open processing has succeeded (step 1006). Here, if the open process of the print data file 4 fails, an error message is displayed (step 1014) and the process ends.

The parameter data stored in the parameter file 2 is checked (step 1007) and it is confirmed whether or not there is an error in the parameter data (step 1008). The check items include, for example, whether the parameter value is omitted, alphanumeric characters are not set in the place where the numerical value should be set, and the specified numerical value is not a negative value. If there is an error in the parameter data, an error message is displayed (step 1014) and the process ends.

Next, the leading print position is set (step 1009). Then, based on the Braille data and the parameter data, Braille print data for a predetermined block copy is generated (step 1010). After that, all files are closed (step 1011), and when the printer is designated as the output method (step 1012).
The print data is output to the printer (step 1013),
The process ends.

Next, the print data generation processing in step 1010 will be described with reference to the flowchart of FIG. First, the distance between a point and (a point) is obtained (step 1101). Next, read the braille data for one character from the braille data file 1 (step 1
102), it is confirmed whether this data is data indicating the end of the file (step 1103).

If the data does not indicate the end of the file, it is confirmed whether the read Braille data is a line feed mark (step 1104). If it is not a line feed mark, the braille code of the read braille data is matched with the braille code stored in the braille code table 6 (step 1105). If there is a match, the coordinate value of each point of the read Braille data is calculated (step 1106).

That is, the coordinate values of the points shown in FIG. 4 are calculated. Also, check whether the method of drawing dots is using a font or a circle (step 110).
7). When the font is designated, the print data is written in the font format in the print data file 4 (step 1108), and when the circle is designated, the print data is written in the circle format in the print data file 4 (step 1109). ).

After that, it is checked whether the X coordinate value of these coordinate values does not exceed the printing range of the block copy (step 1110). If the X coordinate value does not exceed the printing range, the next 1 character from the braille data file 2 is checked. The Braille data for minutes is read (step 1111), and the above processing is performed.

In step 1105, if the braille code of the read braille data and the braille code stored in the braille code table 6 cannot be matched, it is determined whether the braille code of the read braille data is a page break. Confirmation (step 1112), and if the page is not a page break, an error message is displayed and the process ends. If it is a page break, a page break process is performed (step 1113) and the process returns to step 1110. Further, in step 1110, when the value of the X coordinate exceeds the printing range of the block copy, an error message is displayed and the process ends.

On the other hand, in step 1103, when the read Braille data is the mark of the line feed, the coordinates of the point are calculated first (step 1114). From there, the necessary points or coordinates are calculated (step 115). After that, it is checked whether the Y coordinate value out of these coordinate values exceeds the printing range of the block copy (step 11).
16) If not, read the next braille data for one character from the braille data file 2 (step 111
1), the above processing is performed. On the other hand, if the value of the Y coordinate exceeds the printing range of the block copy, an error message is displayed and the process ends.

Although the present invention has been described above with reference to the preferred embodiments, the present invention is not necessarily limited to the above embodiments.

[0044]

As described above, according to the present invention,
Since it is possible to print the ink braille in a desired size and at a desired position, it becomes possible to output a high quality ink braille plate from an output device such as a printer or an image setter. Therefore, even when the braille is enlarged and reduced and output, the size of each point and the interval between the points can be adjusted and output according to the degree of enlargement and reduction. The quality will not be lost due to the imbalance in the above, and high quality black and white Braille copy can be obtained.
