Description

[Detailed description of the invention]

The present invention relates to a programmably controlled printing device. In particular, the present invention relates to an inhibition processing device for a printing device that programmably performs line start and line end inhibition processing according to a fixed priority order. In printed text, if certain symbols, such as punctuation marks, appear at the beginning or end of a line, or extend between the end and beginning of a line, it impairs readability and is therefore undesirable in terms of typographical style. . Examples of these punctuation marks include ",", ".", ")", "〓", etc., which must not appear at the beginning of a line, and "(", "〓", and "<", which must not appear at the end of a line). , ``∧'', etc., and these are called ``line start and line end prohibition symbols''.The process to prevent this prohibition symbol from coming to the beginning or end of a line, or from spanning the end of a line to the beginning of a line is called a line start or line limit prohibition symbol. However, in order to provide space for the symbol or character that should be inserted in the previous line, conventional devices evenly shorten the print character advance of the previous line and print the nails when performing such prohibition processing. For this reason, kanji and punctuation marks such as "?" are printed uniformly, which has the disadvantage of degrading the printing quality.Also, other conventional devices do not handle end-of-line rules. 1 so that punctuation marks such as "(" at the end of the line come to the beginning of the next line.
By removing the number of characters, and increasing the printing interval to compensate for the lack of one character on that line. In this case, either increase the space between the 3 or 4 characters at the end of the line, or
It is processing whether to spread it evenly across the entire line. However, this method of widening the character spacing has the disadvantage that it becomes visually sparse and degrades printing quality. The present invention improves this point by predetermining the order of claw printing according to the type of printed characters in the previous line when performing prohibition processing.
It is an object of the present invention to provide a prohibition processing device that does not impair printing quality, does not make the device complicated, and is especially suitable for small-sized printing devices. The present invention provides means for prioritizing each character of inputted printed character data, means for identifying whether or not to perform prohibition processing on one line of inputted printed character data, and printed characters being inputted. means for storing printed character data of at least one line before the data, and when it is identified by the identifying means that prohibition processing is to be performed, the printed character data stored in the storing means is stored in the storing means; The printed character data is printed in the order of precedence in the above priority order, and Kinsoku processing is performed so that the first character of the next line is packed at the end of the line, and the printing character data that has undergone this Kinsoku processing. The invention is characterized in that it includes a control means including a microprocessor for controlling printing. An embodiment of the present invention will be described based on the drawings. FIG. 1 is a block diagram of essential parts of an embodiment of the present invention. The perforation tape 1 is set on a tape reader 2, and the printed character data is read. The output of this tape reader 2 is led to a tape data memory 3. The output of this tape data memory 3 is led to a comparator circuit 5.

Also, the output of the microprocessor 10 is the first line feed amount memory 20.
guided by. The output of the first row printing pressure memory 19 is led to a hammer drive circuit 23. Further, the output of the first line feed amount memory 20 is led to a paper feed motor circuit 24. The output of the first line type storage position memory 21 is led to a type storage position circuit 25. Here, data shown in Table 1 is written in advance in the memory 6.

[Table] Here, full-width refers to the full width of standard typeface, and half-width refers to half of the total width of standard typeface. In addition, the above counter 7 has (2) shown in Table 1,
Counters are provided to count the numbers (3), (6), (7), and (9), respectively. Furthermore, in the present invention, when a tab is printed on the previous line by prohibition processing, the priority order of the tab printing is determined in advance according to the type of printed character in the order in which the printing quality is least likely to be impaired even if the tab is printed. This priority order is detected by the memory 6 that stores the priority order data and the comparator circuit 5 shown in FIG. FIGS. 2A, B, and C are explanatory diagrams of priorities for nail printing. In this example, the priority order is set from 1st to 3rd. In FIG. 2, the upper row of each of A, B, and C shows the printing state in horizontal writing, and the lower row shows the printing state in vertical writing. FIG. 2A shows an example of a punctuation mark whose priority is set to first place. In Figure 2 A, a is a punctuation mark that can be filled with half-width with full-width feed, b is a punctuation mark that can be filled with a quarter-width with full-width feed, and c is a punctuation mark that can be filled with half-width with full-width feed. d is 1/4 with full-width feed
Indicates each punctuation mark that can be squared. For these punctuation marks a to d, empty spaces are provided on the typeface to make the composition easier to see. For example, the punctuation mark a "," occupies a half-width space for printing, but the half-width space is left blank to make the layout easier to read. For this reason, even if the next characters are printed in the empty spaces of these punctuation marks a to d, the print quality is less likely to be degraded, and therefore, the print quality is given the highest priority. FIG. 2B shows an example of hiragana or katakana characters whose priority is set to second place. These characters are printed in full-width in normal printing, but
The space occupied by the characters themselves is slightly smaller than that of kanji. Therefore, if there are a certain number of these characters in the previous line (for example, 5 or more characters), in order to create the character space necessary for the prohibition processing at the end of the previous line, these characters are evenly allocated and printed. However, the print quality is less likely to be compromised. For this reason, nail printing is given second priority. FIG. 2C shows an example of a kanji or punctuation whose priority is set to third place. Since these characters occupy a large space for printing, printing them with nails will degrade the printing quality. Therefore, the second line is in the previous line.
There are no punctuation marks shown in Figure A, and the number of kana characters shown in Figure B is small (for example, 4 or less in one line).
Only in cases where the printed characters are evenly distributed among all printed characters in a line, the printed characters are printed in a tabular manner. Therefore, it is given the third priority. With such a circuit configuration, the characteristic operation of the present invention will be explained using the first printing example as the head of line processing shown in FIG. In FIG. 3, A shows an example of printing when no prohibition processing is performed, and B in FIG. 3 shows an example of printing when head of line processing is performed by the apparatus of the present invention. That is, as shown in FIG. 3A, when there is a prohibited punctuation mark "," at the beginning of a line, this is a prohibition process in which the "," at the beginning of the line is pushed to the end of the previous line so that it does not come to the beginning of the line. Here, FIG. 4 shows an example of perforation of printed character data corresponding to the printing example of FIG. 3. This print character data is address information of 8 bits each for XY. The printed line is punched as usual, and a new line mark is punched at the end of the line, and in the next printed line, the kinkyaku ``,'' at the beginning of the line is changed to ``,''.
It is punched twice as "," and this gives the line head processing data α. The set number (multiple) of one print line to which this line-first processing data α is given is "," as the line-first processing data α.
It is considered to be the number of characters excluding ",". In other words, in this example, the number of settings is 11, so the total number of characters is 11, including those that span the beginning or end of a line.
After 13 characters are punched out, a line feed sign is punched out. At this moment, the printed character data in the line shown by A in FIG. 3 from the perforated tape 1 is being read out from the tape reader 2. This output is held in the tape data memory 3 from this tape reader 2. This tape data memory 3 stores data for one line from line feed code to line feed code. When the tape data memory 3 stores data for one line in FIG.
Each print character data is sequentially applied to the comparator circuit 5. This comparison circuit 5 compares the contents of the memory 6 shown in Table 1 above for each print character data. The comparison result, the contents counted by the counter 7, and each printed character data are stored in the second line data memory 8. At the same time, the contents of the tape data memory 3 are converted by the address conversion circuit 11 into XY coordinate values within the type storage. Based on this address information, the printing pressure, paper feed amount, and type storage position (servo motor movement amount data) data for each printed character data are stored in the printing pressure memory 12, feed amount memory 13, and type storage position memory 14, respectively. It is stored in the line printing pressure memory 16, the second line feed amount memory 17, and the second line type storage position memory 18. When the printing character data processing for one line is completed, the data of the next line, that is, the line shown in FIG. 3, is read out by the tape reader 2. When the tape data memory 3 stores one row of data, a comparison operation is performed. At this time, the contents of the second row memories 16 to 18 are transferred to the first row memories 19 to 21. In the printed character data of the line currently being compared, the prohibited punctuation marks "," and "," are punched in succession at the beginning of the line (Figure 4), so this is the content of Table 1 in comparison circuit 5. When the second line is stored in the data memory 8 after being compared with the second line, the microprocessor 10 detects this and identifies the line as having head-of-line processing data. As a result, predetermined data is read from the first row data memory 9. As a result, it is identified that there is one punctuation mark "," with the highest priority in the line, and the kinkoku punctuation mark to be pushed into the line is the punctuation mark "," which is half-width closed by full-width forwarding, and the following A feed amount calculation is performed. That is, the space required for Kinsoku processing is half-width, and the punctuation mark with the first priority is "," which is shortened by half-width with full-width forwarding, so it is calculated as 1/2-width/1=1/2-width. This pawl print data is stored in the 1st line feed amount memory 2.
0, and a new feed amount for Kinsoku processing is rewritten. Next, the punctuation mark "," is added to the end of the first line data memory, and the printing pressure of this punctuation mark "," is
The feed amount and the type storage position command are stored in the first line memories 23 to 25, respectively. As a result, the data of this punctuation mark "," is deleted from each of the second row memories 16-18. The comparison operation in the comparison circuit 5 continues, and the comparison operation in the row is completed. A printing operation is performed using the print data subjected to the prohibition processing, and printing of line B in FIG. 3 is performed. That is, as shown in Figure 3a, the punctuation mark "," is printed in half-width space, the space b necessary for Kinsoku processing is formed in half-width space, and the Kinkoku punctuation mark "," at the beginning of the line is printed in this space b. is printed at the end of the line. Similar circuit operations are performed thereafter, and the print control data of the print line being printed is stored in each memory 19 of the first line.
The print control data of the next line is stored in each of the second line memories 16 to 18, and the data of this line, that is, the line two lines after the line where the printing operation is being performed, is stored in the tape reader 2. is being read from.
The printing operation is performed once in each memory 16 to 18 on the second line.
It starts after all data for a row has been stored. FIG. 5 is a second example of printing as the head of line process printed by the apparatus of the present invention. This is a case where the priority is ranked second compared to the first printing example shown in FIG. The space required for the Kinsoku processing is a half-width (1/2-width) space as in the first embodiment, and the number of hiragana characters is five, as shown in the row of FIG. Therefore, as shown in Figure 5a, these five hiragana characters are printed with 1/2 corner/5 = 1/10 corner each, and as shown in Figure 5b, they are printed as required for the start-of-line processing. It is distinctive in that a half-width (5/10 = 1/2-width) space is formed at the end of the line, and a character ``,'', which cannot start a line, is printed here. The other points are the same as the first printing example. FIG. 6 is a third example of printing as a first-of-line prohibition process printed by the apparatus of the present invention. Comparing with the first printing example, there is no first priority, the second priority has four characters or less, and the priority is third. The space required for the prohibition processing is a half-width (1/2-width) space as in the first embodiment, and the number of characters in one line is 11 as shown in FIG. Therefore, as shown in Figure 6a, these 11 characters are printed in 1/2 squares/11 = 1/22 squares, and the space width required for Kinsoku processing is as shown in Figure 6b. is formed at the end of the line by a half-width (11/22 square = 1/2 square), and is characterized by the fact that the character ``,'', which cannot start a line, is printed here. The other points are the same as the first printing example. FIG. 7 is a fourth example of printing in which line end prohibition processing is printed by the apparatus of the present invention. Compared to the first to third printing examples, the feature is that line end prohibition processing is performed. In other words, when the end-of-line punctuation mark "<" is at the end of a line, as shown in line A of Figure 7, the characters packed into the previous line occupy the full-width printing space indicated at the beginning of the next line, as shown in the same line. The kanji ``kin'' has a wide range of meaning. The prohibition processing in this case is performed in the same way as the above-mentioned line head processing, but for ease of understanding, only the distinctive parts will be explained. First, FIG. 8 shows an example of punching of printed character data corresponding to the printed characters shown in FIG. 7B. In Figure 8, the lines are punched normally, with the illegal character "<" being punched at the end of the line, then a line feed sign, and then the illegal character "<" again being punched at the beginning of the next line. The end-of-line processing data γ is provided. The set number of lines in one line to which the end-of-line processing data γ is given is the number of characters excluding the "<" that gives the end-of-line processing data γ. The other points are the same as the punch-input print data for line head processing shown in FIG. In the line-end-of-line processing, as shown in Figure 8, the kinsoku punctuation mark "<" is punched at the end of the line, the line feed symbol is punctured, and the same kinsoku punctuation mark "<" is punched at the beginning of the line. The processor 10 detects the data, reads the necessary data from the first line data memory 9 and the second line data memory 8 in the same way as the line head processing, and calculates the tab print data according to the priority order. This pawl printing data is sent to the first line feed amount memory 20 from which the line feed data shown in FIG. 7 has been read, and a new feed amount for prohibition processing is rewritten. Next, the second printed character "KIN" from the beginning of the line is added to the end of the first line data memory 9. Next, set the printing pressure of this “prohibited” to the second line printing pressure memory 1.
6 and stores it in the first line print pressure memory 19, and reads out the coordinate value position command from the second line type storage position memory 18 and stores it in the first line type storage position memory 21.
to be memorized. As a result, each second row memory 16~
"Forbidden" data is deleted from 18 onwards. In other words, as shown in Figure 7B, there are two half-width punctuation marks in the line with the highest priority, and the space required for Kinsoku processing is full-width, so full-width/2=1. /2, this punctuation mark "," is printed as shown in FIG. 7a, and a space is formed as shown in FIG. FIG. 9 is a fifth example of printing using the line end prohibition process printed by the apparatus of the present invention. When compared with the fourth printing example in FIG. 7, this is a case where the priority is ranked second. The space required for the Kinsoku processing is full-width as in the fourth printing example, and the number of hiragana characters is five, as shown in the row of FIG. Therefore, as shown in Figure 9a, these five hiragana characters are printed with 1 corner/5 = 1/5 corner, and as shown in Figure 9b,
The space required for end-of-line processing is a full-width space at the end of the line (5/5 = full-width), and the kanji character "kin" is printed here. The other points are the same as the fourth printing example. FIG. 10 is a sixth example of printing as a line ending prohibition process printed by the apparatus of the present invention. Comparing with the fourth printing example, there is no first priority, the second priority has four characters or less, and the priority is third. The space required for the prohibition processing is full-width as in the first embodiment, and the number of printed characters in one line is 11, as shown in the line of FIG. Therefore, as shown in Figure 10a, each of these 11 characters is printed by 1/11 = 1/11th corner, and as shown in Figure 10b, the space required for Kinsoku processing is printed with full-width characters at the end of the line. It is unique in that it is made up of only full-width characters (11-byte/11 = full-width characters), and the kanji character "kin" is printed here. The other points are the same as the fourth printing example. In the above example, a perforated tape was used as the input printed character data, but a floppy disk or the like may also be used. As explained above, according to the present invention, the priority order of the pawl printing of the prohibition processing is set in advance in accordance with the type of printed characters, and the information necessary for the prohibition processing is extracted from the printed character data including the prohibition processing information. Based on this information, a processing circuit calculates the tab print information according to the priority order, and based on this tab print information, the print space width of each printed character is set to perform prohibition processing. Therefore, the characters can be printed in order of characters that do not become difficult to read even if they are printed, and the quality of the printing will not be degraded due to spaces appearing on the next line. Further, the number of priority rankings can be increased or decreased as necessary, and the accuracy of prohibition processing can be adjusted and designed depending on the scale of the device, and the performance of the printing device can be significantly improved. It has excellent effects such as being able to reduce costs. In addition, in the present invention, the printing space for the Kinsoku symbol itself is reduced according to its type, so the space for printing the tabs can be reduced, which results in significantly higher quality compared to the conventional Kinsoku processing. Kinsoku processing can be performed.
