Description

[Detailed Description of the Invention] [Table of Contents] Overview Industrial Application Fields Conventional Technology Problems to be Solved by the Invention Means for Solving the Problems Action Examples Effects of the Invention [Summary] Characters and symbols The invention of claim 1 relates to a printer that represents characters by dots, and is intended to record horizontally enlarged characters with high dot density, Based on the character pattern data, a recording means records each column, and in a printer that records characters and symbols, pattern data corresponding to each column forming a character pattern is sequentially input, and one input column repeating means for repeating the pattern data a predetermined number of times and sequentially outputting it as pattern data for a predetermined number of columns; and a calculation means for performing a logical sum operation with the pattern data of the column and supplying the result of this calculation to the recording means as the pattern data of the column, and recording a pattern obtained by enlarging the character pattern by a predetermined number in the horizontal direction. Configure it to do so.

[Industrial application field]

The present invention relates to a printer used as an output device for computers and the like, and particularly to a printer that represents characters and symbols with a plurality of dots.

In dot printers, character patterns are prepared in which characters and symbols are represented by a plurality of dots, and characters and symbols are recorded based on this character pattern.

[Conventional technology]

The standard-sized character pattern in the above-mentioned dot printer is formed by, for example, 8 x 8 dots arranged vertically and horizontally, and the character pattern data is used to indicate whether or not to record each of the dots described above. It has become. The vertical arrangement of dots forming this character pattern is called a column, and in wire tod printers, dots are recorded in each column.

Hereinafter, the dot data corresponding to the first column in the character pattern data will be referred to as the i-th column pattern data.

Further, the horizontal enlarged pattern data is created by arranging the pattern data of the i-th column of the standard size character pattern data mentioned above as the pattern data of the 2nd (i-1)+1 column and the 21st column of the horizontal enlarged pattern. It is used to emphasize recorded characters.

Further, the above-mentioned standard size character pattern may be expressed in 16 columns, and, for example, the recording positions of the odd-numbered columns and the even-numbered columns may be shifted by half a dot. At this time, the above-mentioned recording position of the odd-numbered column is called a half-dot position. By using such a character pattern, it is possible to improve the density of recorded dots, and to smoothly express diagonal patterns included in characters and symbols, thereby improving printing quality.

On the other hand, for example, in a wire tod printer (hereinafter simply referred to as a printer) that has a print head in which eight printing pins are arranged in a row, a predetermined period of time is required in order to excite each printing pin and fire it. Therefore, it is not possible for the - number of pins to print continuously at the normal dot position and the above-mentioned half dot position. Therefore, in the printer described above, it is necessary to create character pattern data so that dot data corresponding to the same bin in adjacent columns do not become logic "1" indicating printing at the same time.

For example, as shown in FIG. 9(a), for a pattern corresponding to a horizontal line that constitutes a character, the corresponding dot data in the pattern data in column 3.5.7 corresponding to the half dot position, for example, is Character pattern data is created by masking.

By printing using this character pattern, even in such a printer, as shown in FIG. 9(b),
The printing results are such that the dots in the diagonal direction are smoothly continuous.

[Problem to be solved by the invention]

By the way, when a horizontally enlarged character pattern of the character pattern shown in FIG. 9(a) is created using the conventional method described above, as shown in FIG. 9(C), the pattern data of two adjacent columns is , pattern data in the same column of standard character pattern data is arranged. Therefore, if you mask one of the data corresponding to the same pin in consecutive columns for this character pattern data,
This results in coarse character pattern data as shown in FIG. 9(d), and when printing is performed using this character pattern data, there is a problem in that the printing result is extremely low in density.

SUMMARY OF THE INVENTION An object of the present invention is to provide a printer capable of recording horizontally enlarged character patterns with high dot density.

[Means to solve the problem]

FIG. 1(a) is a block diagram of the principle of the invention according to claim 1. Also, the first version) is a block diagram of the principle of the invention according to claim 2.

i-゛1.■ In FIG. 1(a), the recording means 101 records each column based on character pattern data representing a character pattern formed by a plurality of columns each consisting of a plurality of dots, In a printer for recording characters and symbols, the repeating means 11.1 receives pattern data corresponding to each column forming a character pattern sequentially and repeats the inputted pattern data of one column a predetermined number of times. , sequentially output as pattern data of a predetermined number of columns.

The calculation means 121 receives the output of the repetition means 111 continuously, performs an OR operation on the pattern data of each column and the pattern data of the column before the column, and uses the result of this operation as the pattern data of the column. , is supplied to the recording means 101.

The overall configuration is such that a pattern obtained by enlarging a character pattern by a predetermined number in the horizontal direction is recorded.

In FIG. 1(b) of ii-;'2, the recording means 101 records each column based on the character pattern data, and the converting means 141 in the printer that records characters and symbols,
Pattern data corresponding to each column forming a character pattern is input successively, and a logical OR operation is performed between the pattern data of each column and the pattern data of the column before the column.

The synthesizing means 151 receives the pattern data corresponding to each column forming a character pattern and the calculation result from the converting means 141, and converts the pattern data of each column and the output of the converting means 141 into pattern data of two adjacent columns. It is supplied to the recording means 101.

As a whole, it is configured to record a pattern in which a character pattern is enlarged twice in the horizontal direction.

[Function] In the invention of claim 1, the character pattern is formed of a plurality of columns each consisting of a plurality of dots,
The pattern data corresponding to each column forming this character pattern is sequentially input to the repeating means 111, and the inputted pattern data of one column is repeated a predetermined number of times by the repeating means 111. It is sequentially output as several minutes of pattern data. This iterative means 1
The pattern data outputted by 11 corresponds to each column of the horizontally enlarged pattern generated by the conventional method.

Here, for example, if a vertical line of a character pattern is represented by one column, the pattern data of the column corresponding to this vertical line (hereinafter referred to as the i-th column) and the next i+1-th column are as described above. The repeating means 111 generates N columns of pattern data.

These pattern data are input to the calculation means 121,
A logical sum operation is performed between the pattern data of each column and the pattern data of the column preceding the column. As a result, the pattern data in the first column of the N columns of pattern data corresponding to the i+1th column described above is
This is the logical OR operation result of the pattern data of the column and the pattern data of the i+1th column.

Therefore, in the pattern data output from the calculation means 121, the vertical line expressed by one column of pattern data in the above-mentioned character pattern will be expressed by N+1 columns.

In the invention of claim 1, the iterating means 111 allows -
Once pattern data corresponding to the pattern data of each column of the horizontal expansion pattern according to the conventional method is generated, based on the output of this repeating means 111, the calculating means 121 performs the following:
A horizontally enlarged pattern is generated. In addition, this calculation means 12
Based on the output of step 1, the recording means 101 records each column, thereby enlarging the character pattern formed by the input pattern data of each column by a predetermined number (for example, an integer N) in the horizontal direction. A pattern is recorded.

As mentioned above, the vertical lines of this horizontally enlarged pattern are equal to N of the number of columns of pattern data representing the vertical lines of the original character pattern.
It is expressed as a column of numbers multiplied by 1. As a result, even if the necessary mask processing is applied to a printer that cannot record normal dot positions and half dot positions consecutively, the vertical lines of the horizontally enlarged pattern, which are doubled in the horizontal direction, can be expressed in at least two columns. This makes it possible to perform recording with high dot density.

The pattern data corresponding to each column forming the character pattern of ii''; Further, the pattern data corresponding to each column mentioned above and the calculation result by the conversion means 141 are combined with the combination means 15.
1 will be introduced.

Here, in the invention of claim 1 described above, the predetermined number N
When r2j is defined as r2j, two consecutive columns of pattern data generated by the above-mentioned repeating means 111 and calculation means 121 correspond to each input column, and the pattern data of each column is the turn data of each column and the corresponding column. This is the logical sum of the pattern data of the column and the pattern data of the column input before the column.

Therefore, by combining the pattern data of each introduced column and the output of the above-mentioned converting means 141 into continuous two-column pattern data by the synthesizing means 151, the vertical line A horizontally enlarged pattern is generated in which vertical lines are expressed by the number of columns equal to twice the number of columns of pattern data representing .

In the invention of claim 2, based on the calculation result by the conversion means 141 and the pattern data of each column,
The synthesizing means 151 generates a horizontally enlarged pattern in which the input character pattern is enlarged twice in the horizontal direction, and the recording means 101 performs recording based on this horizontally enlarged pattern. Therefore, for example, if the vertical line of the original character pattern is expressed by one column of pattern data, the vertical line of the horizontally enlarged pattern is expressed by three columns of pattern data. As a result, even with printers that cannot record normal dot positions and half dot positions continuously,
It becomes possible to perform recording with high dot density.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 2 shows the configuration of a printer according to an embodiment of the present invention.

In FIG. 2, the wire dot printer (printer) includes a character generator (CG) ROM 211 that stores standard-sized character pattern data, a memory 212 that stores programs and data, and a A printing section 213 that performs printing;
Microprocessor (MPU) 214 that controls each part
It is composed of: Moreover, this MPU214 and CGROM211. Memory 212. The printing section 213 is
connected to each other via a bus.

The above-mentioned printing unit 213 includes a print head 231 having, for example, eight pins arranged in a row to record dot data for one force ram, and a head moving unit 232 that moves this print head 231 from side to side. Configured with the necessary features.

Also, in the CGROM 211, as in the example of the character pattern shown in FIG. Character pattern data created so that the logic does not become "1" is stored. The CGROM 211 is also configured to output character pattern data representing the corresponding characters and symbols in accordance with character codes representing the characters and symbols input as an address.

FIG. 3 shows a flowchart showing a general printing operation by this printer.

First, via a communication interface (not shown), etc.
For example, print data consisting of m character codes and attribute instructions for horizontal expansion of character pattern data is supplied and stored in the memory 212 described above (step 3).
01), in response to this, the printing operation for this print data is started.

The MPU 214 sequentially inputs the character codes included in the print data described above into the CGROM 211, and sequentially stores the output character pattern data in the memory 2 (step 302).

Next, the MPU 214, based on the attribute instruction described above,
It is determined whether or not horizontal enlargement of the character pattern data is instructed (step 303). If the determination in step 303 is affirmative, a conversion process to be described later is performed and the processing result is stored in the memory 212 (step 304). On the other hand, in the case of a negative judgment in step 303, step
Steps 305 to 307 are performed without performing the conversion process in step 304.

Next, the MPU 214 drives the head moving section 232 of the printing section 213 described above (step 305). In response to this, the head moving unit 232 starts operating and moves the print head 231 at a predetermined speed.

Thereafter, the MPU 214 sequentially supplies the character pattern data stored in the memory 212 to the print head 231 one column at a time, for example (steer knob 306).

Based on the pattern data of each column supplied in this way, printing is performed by the print head 231, and when printing of all the character pattern data stored in the memory 212 is completed, the MPU 214 23

), the process ends.

The conversion process for horizontally enlarging the character pattern data in step 304 described above will be described below.

The MPU 214 is configured with a horizontal enlargement processing section 240 that performs the above-mentioned conversion processing, and this horizontal enlargement processing
0 is composed of an iterative processing section 241 corresponding to the repeating means 111 of claim 1, an arithmetic processing section 242 corresponding to the arithmetic means 121 of claim 1, and a mask processing section 243 that performs mask processing to be described later. There is.

FIG. 4(a) shows a flow chart showing the operation of the iterative processing section 241 according to the embodiment, and FIG. 4(b) shows a flow chart showing the operation of the arithmetic processing section 242 according to the embodiment.

Here, the above-mentioned iterative processing unit 241 performs a process of converting m standard size character pattern data into intermediate data and data similar to conventional horizontally enlarged character patterns. Further, the arithmetic processing unit 242 substitutes pattern data Z(i) of each column of this intermediate data into equation (1) to obtain pattern data Y( of each column of the horizontally enlarged character pattern).

In the figure, X (j, k) (k = 1 to 16) is the jth (j = 1
The pattern data of each column of the character pattern data of ~m) is shown.

Further, the above-mentioned intermediate data and horizontal enlarged data are formed from enlarged character pattern data corresponding to each of the above-mentioned m standard size character pattern data. Each enlarged character pattern data consists of 32 columns.

First, the iterative processing unit 241 generates a variable i indicating a column of intermediate data and horizontally enlarged data, a variable j indicating the order among m standard-sized character pattern data, and a column of standard-sized character pattern data. An initial value FIJ is set for each variable indicating (steps 401 and 40)
2,403).

Next, pattern data Z (
Step 404) sets the pattern data X(j, k) of the first column of the j-th standard size character pattern data in step 404), and increments the variable i by rl (step 405). Similarly, the pattern data X (j, k) of the standard size character pattern data described above is set to the pattern data Z (i) of the intermediate data indicated by the variable i incremented in step 405. In step 406), the variable After incrementing i (step 407), variable k is incremented (step 408).

Next, the iterative processing unit 241 compares the value of the variable with the number of columns L (for example, 16) forming the standard size character pattern data (step 409).

If the value of the variable is smaller than or equal to the number of columns described above, an affirmative determination is made in step 409. In this case, steps 404 to 409 described above are repeated.

In this way, the iterative processing unit 241 processes the pattern data X (
j, k) are each repeated twice and placed in the corresponding two columns of intermediate data. As a result, the 6th
Based on the character pattern data shown in FIG. 6(a), intermediate data corresponding to conventional horizontally enlarged character pattern data is created (see FIG. 6(b)).

On the other hand, in the case of a negative determination in step 409, the iterative processing unit 241 determines that the creation of intermediate data corresponding to one standard size character pattern data has been completed, and
The variable j is incremented (step 410).

Next, the iterative processing unit 241 compares this variable j with the number of characters m mentioned above (Step 411),
If it is smaller than or equal to , an affirmative determination is made in step 411, and the process returns to step 403 to create intermediate data corresponding to the next character pattern data.

In this way, steps 403 to 411 are repeated, and when intermediate data corresponding to all m character pattern data has been created, step 41
1 is negative.

In this case, the value of the variable i at this time is held as the total number of columns n of the intermediate data (step 412), and the process ends.

Hereinafter, the arithmetic processing unit 242 processes the intermediate data Z(i

First, the arithmetic processing unit 242 sets the intermediate data Z(1) to the horizontally enlarged data Y(1) (step 421), and sets the variable i.
Set Ir2J as the initial value of (step 422)
.

Next, the arithmetic processing unit 242 increments the variable i in step 423L to set the result of the logical sum operation of the intermediate data Z (i) and the intermediate data Z (i-1) in the horizontally enlarged data Y (i) ( Step 424).

Thereafter, the arithmetic processing unit 242 compares the variable i and the total number of columns n of the intermediate data described above, and in step 425L, if the variable i is smaller than or equal to the total number of columns n of the intermediate data, an affirmative determination is made in step 426. Then, steps 423 to 425 described above are repeated.

On the other hand, if the determination in step 425 described above is negative, the arithmetic processing unit 242 determines that the processing for all columns has been completed, and ends the processing.

In this way, the intermediate data shown in FIG. 6(b) is
As shown in FIG. 6(C), a pattern representing vertical lines of characters is converted into horizontally enlarged data formed from three columns.

Here, the print head 231 described above cannot print continuously at the normal dot position and the half dot position. Therefore, the mask processing section 243 performs a process of masking the dot data corresponding to the half dot position or the normal dot position of the corresponding portion of the horizontally enlarged data generated by the arithmetic processing section 242 described above.

For example, the mask processing unit 243 calculates the converted horizontally expanded data Y'(i) using equation (2), assuming that the pattern data of the i-th column of the converted horizontally expanded data is Y'(i). Bye.

Y' (i) = (Y (i)△Y' (i-1))
■Y(i)...(2) However, Y'(0)=O (i.e.
All dot data is logic “0”), and the formula (1
), the operator Δ indicates a logical AND operation, and the operator indicates an exclusive OR operation.

FIG. 6(d) shows converted data obtained by converting the horizontal enlarged pattern shown in FIG. 6(C) described above using equation (2).

As described above, iterative processing unit 241. Arithmetic processing unit 242. Horizontal enlargement processing unit 24 consisting of a mask processing unit 243
0, horizontally enlarged data is generated. By supplying the pattern data of each column of this horizontally enlarged data to the print head 231 of the print section 213, the print head 231

In addition, in the above-mentioned embodiment, a case has been described in which standard-sized character pattern data is enlarged twice in the horizontal direction, but there is no limit to the magnification for horizontal enlargement, and using the first method described above, It is possible to create horizontally enlarged data that is horizontally enlarged N times (where N is a positive integer).

In this case, the iterative processing unit 241 described above performs step 4.
The processes of steps 04 and 405 may be repeated N times.

In addition, the above-mentioned iterative processing section 241 and arithmetic processing section 24
2 may be realized by hardware.

By the way, in the horizontal expansion data obtained by the conversion process by the iterative processing unit 241 and the arithmetic processing unit 242 described above, the pattern data Y (2i) of the 21st column and the pattern data Y (2i+1) of the 2i+1 column are each expressed by the formula ( 3) Expressed by equation (4).

The conversion process according to the embodiment of claim 2 will be explained below. FIG. 8 shows a flowchart representing the conversion processing operation according to the embodiment of claim 2.

First, the composition processing unit 742 adds pattern data X (1, 1) of the first column of the first standard size character pattern data to data Y (1) of the first column of the horizontally enlarged data.
(step 8.01), and set the initial value f2 to the variable i.
The initial value 1'1' is set for the variable j and the variable J (steps 802 and 803).

Thereafter, the conversion processing section 741 and the composition processing section 742 repeat the processing of steps 804 to 808, which will be described later, until a negative determination is made in step 808.

First, the synthesis processing unit 742 adds pattern data Y (i) of the i-th column of the horizontal enlarged data to pattern data X of the j-th standard size character pattern data.
(j, k) is set in step 804 (see equation (3)), and variable i is incremented (step 805).
. Next, the conversion processing unit 741 performs a logical OR operation on the pattern data X (j, k) of the standard size character pattern data mentioned above and the pattern data X (Lk+1).
Step 8069 (see equation (4)), this calculation result is supplied to the synthesis processing section 742. Accordingly, the composition processing unit 7
42 is the pattern data Y of the i-th column of the horizontal expansion data.
In (i), set the calculation result by the conversion processing unit 741,

Processing for odd columns based on 4) is performed.

The synthesis processing unit 742 compares the number of columns of the standard size character pattern data with the variable in step 8.
08), when the variable k is larger than the number of columns, a negative determination is made in step 808.

At this time, the synthesis processing unit 742 determines that the conversion process for one character has been completed, increments the variable j (step 809), and compares the variable j with the number of characters m (step 810).

In this step 810, it is determined that the variable j is larger than the number of characters m, and the steps 803 to 810 described above are repeated until a negative determination is made in step 810.

In this way, the horizontal enlarged data shown in FIG. 6(C) can be directly obtained based on the standard size character pattern data shown in FIG. 6(a).

Further, this horizontally enlarged data is introduced into the mask processing section 243, where it is subjected to the above-described mask processing, and printing is performed by the printing section 213 based on the result of this mask processing.
