Abstract

PURPOSE:To obtain legible reversed characters by providing an interpretation device which interprets whether a character pattern has been enlarged or decoratively processed, and a boldface processing device and a reversing device for a character pattern. CONSTITUTION:If a character pattern is read from a character pattern part 1, an interpretation part 2 interprets whether the pattern is an enlarged or decoratively processed data by comparing it with a reference character pattern. After that, the interpretation part 2 sends the pattern data which has been read to a reversion part 4 as it is, if the part 2 interprets it as an enlarged character pattern to which enlargement process has been applied. The reversion part 4 reverses the enlarged character pattern transmitted and sends the reversed data to a printing part 5. In the meantime, if a character pattern to which enlargement process or decorative process has not been applied as yet is read from the character pattern part 1, this pattern data is transmitted to a boldface correction part 3. The boldface correction part 3 processes said pattern data so that the boldfaced characters are produced. After that, the boldface correction part 3 sends the boldfaced character data to the reversion part 4. The reversion part 4 reverses the character pattern and transmits its data to the printing part 5.

Description

TECHNICAL FIELD The present invention relates to an inverted character 1i control circuit for a dot printer, and more particularly to inverted character control by an inverted character control circuit for a dot printer.

BACKGROUND ART Conventionally, in the inverted character control circuit of this type of dot printer, as shown in FIG. , the reversal process is performed in the reversing unit 4, and the printing unit 5
was printing.

In other words, as shown in Figure 5, the character pattern "plate"
The enlarged character pattern [see FIG. 5(b)] is the character pattern N1, which is the enlarged character pattern [see FIG. 5(b)].
If the enlarged character pattern is to be inverted, the bold correction unit 3 performs bold processing on the enlarged character pattern [see FIG. 5(c)].

This bold enlarged character pattern is inverted by the inverting unit 4 and then sent to the printing unit 5 [see FIG. 5(d)].

In such a conventional inverted character control circuit of a dot-type printer, the bold type correction unit 3 is able to read out the character pattern from the character pattern unit 1 regardless of whether it has been enlarged or decorated. Since we simply performed bold processing, reversed it in the reversing unit 4, and printed it in the printing unit 5, the bold processing made the characters too thick, so even though we reversed them, the vertical dot lines etc. became thinner, making the characters difficult to read. It has the disadvantage of becoming.

Purpose of the Invention The present invention has been made in order to eliminate the drawbacks of the conventional ones as described above, and is a dot type that can obtain inverted characters that are easy to see even in character patterns that have been subjected to other processing such as enlargement processing and decoration processing. The purpose is to provide an inverted character control circuit for printers.

Structure of the Invention The inversion character control circuit for a dot type printer according to the present invention has the following features:
A reversal character control circuit for a dot type printer, comprising a bold processing means for performing bold processing on a character pattern, and an inversion processing means for reversing the character pattern, the circuit being capable of performing enlargement processing, decoration processing, etc. on the character pattern. A determination means is provided for determining whether or not other processing has been performed on the character pattern, and when the determination means determines that the other processing has been performed on the character pattern, the reversal processing means When the character pattern is inverted and printed, and the determining means determines that the other processing has not been performed on the character pattern, the bold character processing is performed by the bold character processing means, and then the reversing process is performed. The present invention is characterized in that printing is performed by inverting the character pattern using means.

Embodiment Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, a determining section 2 determines whether the pattern data read from the character pattern section 1 is processed data after bold processing, enlargement processing, or decorative processing.

When the pattern data is determined to be processed data by the determining section 2, the pattern data is sent to the inverting section 4, inverted by the inverting section 4, and then printed by the printing section 5.

On the other hand, if the determining unit 2 determines that the data is not processed data,
The pattern data is sent to the bold type correction section 3, where the pattern data is subjected to bold type processing, and then sent to the inversion section 4. Thereafter, the pattern data is inverted by the inverting section 4 and then printed by the printing section 5.

FIGS. 2 and 3 are diagrams showing an example of character pattern processing according to an embodiment of the present invention. FIG. 2 shows an example of processing a character pattern that has been subjected to enlargement processing, and FIG. 3 shows an example of processing a normal character pattern.

The operation of one embodiment of the present invention will be explained using these FIGS. 1 to 3.

When the enlarged character pattern that has been subjected to enlargement processing is read out from the character pattern section 1, the judgment section 2 first determines whether the pattern data read out from the character pattern section 1 has been subjected to other processing such as enlargement processing or decoration processing. This data is determined by comparing it with the basic character pattern "dish" [see FIG. 2(a)].

In this case, the determining unit 2 determines that the pattern data read from the character pattern unit 1 is an enlarged character pattern that has been subjected to an enlargement process [see FIG. It is sent to the reversing section 4 as it is without being sent.

The inverting unit 4 inverts the enlarged character pattern sent from the determining unit 2 [see Figure 2 (C)] and sends the data to the printing unit 5.
Send to.

As a result, even in an enlarged character pattern that has been subjected to enlargement processing, it is possible to obtain inverted characters that are easy to see without making the characters too thick due to bold processing or making vertical dot lines thinner even after inversion processing.

On the other hand, if a character pattern that has not been subjected to any other processing such as enlargement processing or decoration processing is read out from the character pattern section 1, first the judgment section 2 determines whether the pattern data read out from the character pattern section 1 has been subjected to enlargement processing or decoration processing. The basic character pattern "H" indicates whether the data has undergone other processing such as processing.
Judgment is made by comparing with [see FIG. 3(a)].

In this case, the determination section 2 separates the pattern data read from the character pattern section f11 from character patterns that are not subjected to other processing such as enlargement processing or decoration processing, and sends the pattern data to the bold correction section 3.

The bold correction section 3 performs bold processing on the pattern data (see FIG. 3(b)), and then sends it to the inversion section 4.

The reversing section 4 inverts the bold character pattern sent from the bold correcting section 3 [see FIG. 3(c)], and sends the data to the printing section 5.

In this way, the I'll cutting section 2 determines whether or not the pattern data read from the character pattern section 1 is a character pattern that has been subjected to other processing such as enlargement processing or decoration processing, and the determination result is Therefore, by having the bold type correction unit 3 decide whether or not to perform bold type processing, the inverted printed characters of bold characters, enlarged characters, or decorative characters may become too thick, flattened, bold characters, etc. It is possible to obtain inverted characters that are easy to see even if they are enlarged characters or decorative characters.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, it is determined whether or not a character pattern has been subjected to other processing such as enlargement processing or decoration processing, and the other processing is applied to the character pattern. When it is determined that the character pattern has been processed, the character pattern is reversed and printed, and when it is determined that no other processing has been performed on the character pattern, bold processing is performed on the character pattern. By inverting and printing after printing, it is possible to obtain inverted characters that are easy to see even if the character pattern has been subjected to other processing such as enlargement processing or decoration processing.
