Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device for displaying characters, symbols, etc., or an output device for recording them, such as those used in office computers, word processors, etc.

The present invention is characterized by the output device in which a certain output character or symbol is emphasized or a pattern is provided as a type of horizontal ruled line, and the pattern is used to make a monotonous document more legible.

Another feature is that it is equipped with a wide variety of patterns and can select and generate a desired pattern.

Furthermore, another feature is that it has distance information that specifies the line in which the pattern is printed, and by giving this distance information together with a certain character pattern, it is possible to output one line of the character pattern and print that character pattern. The pattern can be output from the output position to a row at a position corresponding to the distance information.

The present invention will be described below with reference to an embodiment shown in the drawings, using a dot printer as an example of the output device.

First, to give an overview of the present invention, a dot printer is composed of a 24 x 24 dot matrix as shown in Fig. 1, and this scanning starts from the 0th dot in the 0th column to the 1st dot and the 2nd dot. ..., the 23rd dot is scanned, and then the 0th dot of the 1st column is scanned sequentially in the same manner, and this is done until the 23rd dot of the 23rd column is scanned, completing the scanning of the 24 x 24 dot matrix. . Then, dot printing is performed at the matrix position corresponding to the character signal, and dot printing is not performed at the matrix position where there is no character signal.

On the other hand, FIG. 2 shows an example of a pattern as a background pattern for the character record shown in FIG. 0th dot in the 0th column, 2nd dot in the 2nd column
Dots are printed in 12 unit sections, and this 24×8 pattern is repeatedly generated in the horizontal direction.

As can be seen from the unit section (4×4), this pattern is a printing pattern in which dots are printed every other dot in the vertical and horizontal directions.

Such a pattern is superimposed on the character pattern shown in FIG. 1 by means of a summation circuit, thereby recording characters having a background as shown in FIG. 3. In this case, the background pattern in this example is suitable for emphasizing recorded characters.

In addition, although one of the pattern patterns is shown in Fig. 2, there are various other pattern patterns (24 x 8 dot matrix pattern) as shown in Figs. 4 and 5.
A rich variety of character expressions can be created by equipping the computer with a 100% font and selecting predetermined ones of these patterns to generate arbitrary patterns.

Next, a control configuration for specifically executing the above-described operation is shown in FIG. 6, and the control circuit will be described below.

1 is a CPU, 2 is a character pattern generator, and 3 is a dot printer such as an inkjet printer. Generates a character pattern in synchronization with the clock signal CL from
It is supplied to the dot printer 3 via the OR gate _G1 .

On the other hand, 4 is a 24-digit counter that counts the clock signal CL from the dot printer 3, and serves as a dot counter that counts the 0th to 23rd dots in the dot matrix shown in FIG.

5 is an octal counter that counts the output clock of the 24-ary counter 4;
˜This is a column counter that performs the seventh count.

Reference numeral 6 denotes a pattern pattern generator having a ROM configuration holding a large number of pattern patterns as shown in FIGS. The outputs (A to E) of the octal counter 5 are given, and the middle three bits are given the outputs (A to C) of the octal counter 5. If the ROM 6 holds about 16 patterns, 4 bits are required for this pattern selection, and the upper 4 bits of the ROM 6 contain the CPU 1.
It is given as a pattern selection signal.

The pattern output from the ROM 6 is input to one side of the AND gate _G2 . This AND gate _G2 is a control gate that is effective when generating a pattern, and is a control gate that is effective when generating a pattern.
A control signal BC for instructing a different pattern and a gate output signal from an OR gate _G3 are applied as the other inputs.

The output of the AND gate _G2 is then introduced to the OR gate _G1 described above, where the character pattern signal and the pattern pattern signal are superimposed.

On the other hand, in order to execute the operation control as shown in FIG. 7, the CPU 1 sends a simultaneous print signal AP, in addition to the pattern selection signal and control signal BC, depending on the presence or absence of distance information about the pattern.
and outputs the pattern print signal BP.

In other words, there is no distance information when recording only normal text information or when text information and pattern print are recorded simultaneously on the same line, and when text information and pattern print are recorded separately as described later, pattern print Distance information is used to indicate the location of.

The simultaneous print signal AP and pattern print signal
Both BP are input to the OR gate _G3 , and the pattern print signal BP is input to the AND gate _G4 via the inverter I.

The output of the OR gate _G3 serves as the input of the AND gate _G2 , as described above. Moreover, the character pattern signal from the above-mentioned character pattern generator 2 is inputted to the other input terminal of the AND gate _G4 , and the character pattern signal is inputted to the other input terminal of the AND gate G4.
It is led to the above-mentioned or gate _G1 via _G4 .

Further, the CPU 1 is configured to send a paper feed signal PF to the dot printer 3 in relation to the distance information.

The specific operation of the circuit configuration shown in FIG. 6 will be explained in detail together with the operation flow shown in FIG.

[1] Normal character recording operation When only normal character recording is performed, the control signal BC is not output from the CPU 1, and therefore the AND gate _G2 is in an off state.

Also, both the simultaneous print signal AP and pattern print signal BP are not output from CPU1 (“0” state),
Therefore, inverter I of pattern print signal BP
AND gate _G4 is turned on by the signal via.

In this state, a character code is supplied from the CPU 1 to the character pattern generating device 2, and the character pattern is supplied from the device 2 to the dot printer ₃ via the AND gate _G4 and the OR gate G1.

Therefore, the recording state at this time is that only character information is recorded.

[2] Simultaneous recording of character recording and pattern pattern As shown in A in FIG. Since the character information recording section 11 and the pattern 12 are located in the row, the distance information is "0".

In this case, as shown in the operation flow of FIG. 7, first, in step _N1 , the CPU 1 outputs a pattern selection signal, and then the process proceeds to step _N2 to check the presence or absence of distance information.

Now, since the distance information is "0" here, proceed to step _N3 , and the simultaneous print signal AP is "1".
Output. Next, the process advances to step _N4 , where the character code and control signal BC are output.

In this state, the simultaneous print signal AP and the control signal BC are applied to the input side of the AND gate _G2 , and the gate _G2 is enabled, and the pattern print signal BP is in the "0" state, so the inverter is activated. AND gate _G4 is turned on by the signal via I.

Therefore, in synchronization with the clock signal CL from the printer 3, a character pattern corresponding to the character code is output from the character pattern generator 2 and sent to the OR gate _G1 via the AND gate _G4 , and is also applied to the clock signal CL. The dot counter of the 24-decimal counter 4 and the column counter 5 of the octal counter 5 operate synchronously.

Therefore, there are input signals at the lower, middle, and upper addresses of the pattern generator (ROM) 6.
The predetermined pattern selected by the pattern selection signal input to this upper address is the AND gate.
You will be guided from G ₂ to Or Gate G ₁ . Then, at the OR gate _G1 , the character pattern and the pattern pattern are superimposed and sent to the printer 3.

In the printing operation (step _N5 ) in this case, characters are recorded having a background pattern as shown in A of FIG.

[3] Separate recording of character recording and pattern pattern As shown in FIG. This is a case where you want to record it.

The pattern 12 in FIG. 8B is the fifth pattern.
The pattern shown in the figure is selected and generated continuously in the horizontal direction.

In this case, the CPU ₁ first outputs a pattern selection signal at step N1 in the flowchart of FIG. 7, and then proceeds to step _N2 to check the presence or absence of distance information.

Now, since distance information (Nmm) is available here, proceed to step _N6 . Here, the character code and control signal BC are output.

In this case, since the simultaneous print signal AP and the pattern print signal BP are not outputted from the CPU 1, the ANDGATE _G2 becomes invalid and the ANDGATE _G4 becomes valid.

Therefore, by outputting the character code, a character pattern corresponding to the character code is output in synchronization with the clock signal CL and sent to the dot printer ₃ via the OR gate G1.

For this reason, the character information recording section 11 shown in FIG. 8B
Only recording is performed (step _N7 ).

Steps are performed based on the completion of recording the character information.
Proceeding to step _N8 , the paper feed signal PF is output, paper feeding is controlled according to the distance information (Nmm), and the process then proceeds to step _N10 , where the pattern print signal BP is output.

In response to the "1" output of the pattern print signal BP, the AND gate _G2 becomes valid and the AND gate _G4 becomes invalid.

Next, the process proceeds to step _N11 , where a printing instruction is given, whereby a pattern is output in synchronization with the clock signal CL, and is sent to the dot printer ₃ via the AND gate _G2 and the OR gate G1.
At this time, AND gate _G4 is disabled and no character pattern is generated.

For this reason, one line of pattern printing (step
N ₁₂ ) is executed.

Therefore, by providing distance information in relation to certain character information, it is possible to independently control recording of the character information and pattern recording from the recording position to a position according to the distance information.

This means that when creating one line of horizontal ruled lines, underlines, bar graphs, etc. in various pattern patterns, you can create them simply by providing distance information in relation to certain character information, which is extremely convenient. It becomes easy.

As described above, in the present invention, a pattern pattern generator that holds a plurality of types of pattern patterns is provided separately from a character pattern generator for characters or symbols, and a desired pattern pattern is generated from among the plurality of pattern patterns. By selecting and outputting character patterns and pattern patterns at the same time, it is possible to form a background pattern for the character pattern, allowing rich character expressions.Also, by providing distance information of the pattern pattern in relation to the character information, it is possible to create a background pattern for the character pattern. A pattern of character information is output, and a selected pattern pattern is outputted at a position in the row direction (vertical direction) according to the distance information from that position, and is separated by an arbitrary distance from one line of the character pattern. Output control (display/recording) can be easily performed by dividing one line of a pattern pattern, and the distance information only provides the distance (interval) from the related character output line. Input becomes easy, and control of the mutually related character output and pattern pattern output becomes easy, and it becomes easy to create horizontal ruled lines, underlines, etc. of various patterns.
