Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character pattern generator for generating a character pattern to be output to an output device such as a printer based on an input character code.

[0002]

2. Description of the Related Art FIG. 2 is a block diagram showing a conventional character pattern generator disclosed in Japanese Patent Publication No. 53-41017. In the figure, 1 is a character pattern memory that stores a plurality of character patterns in an outline format, and 2 is a character pattern memory based on a character code input from the outside.
An address circuit for generating an internal code for accessing the character pattern memory 1.

Reference numeral 3 is a conversion circuit for generating a character pattern in a corresponding dot format on the basis of the outline format character pattern read from the character pattern memory 1, and 4 is a dot format character generated by the conversion circuit 3. It is a 1-character buffer that stores patterns in character units.
An output conversion circuit 5 converts the character pattern accumulated in the 1-character buffer 4 into a data format for output.
An output device 6 executes output processing such as printing of data from the output conversion circuit 5.

Next, the operation will be described. In a character pattern generator, generally, each character pattern is stored in a character pattern memory in an outline format instead of a dot format,
The character pattern memory capacity is saved. Here, the character code sent to the character pattern generator by input from the host computer or MT input is converted into an internal code by the address circuit 2.

This internal code is the character pattern memory 1
The outline-format character pattern stored in advance is read from the storage area designated by the above. The read out outline-shaped character pattern is sent to the conversion circuit 3, converted into a dot-shaped character pattern, and temporarily stored in the one-character buffer 4 on a character-by-character basis.

The output conversion circuit 5 sequentially reads the dot-shaped character patterns stored in the 1-character buffer 4, converts them into a data format for print output, and sends them to the output device 6. The output device 6 prints it on paper or the like and performs output processing.

[0007]

Since the conventional character pattern generator is configured as described above, external characters and the like not registered in the character pattern memory 1 can be processed if the character pattern is an outline format. In Although,
The dot format cannot be directly processed, it must be converted to the outline format in advance by a host computer, etc., and the external character dot font in the print data cannot be processed, resulting in poor data compatibility. was there.

The present invention has been made to solve the above problems, and an object thereof is to obtain a character pattern generator capable of directly processing dot-type character patterns.

[0009]

In a character pattern generator according to the present invention, when a dot-shaped character pattern is input together with a character code, the character code is internally designated to a predetermined storage area in the character pattern memory. The address circuit has the function of converting to a code, converts the input dot format character pattern to an outline format character pattern, and stores it in the storage area of the character pattern memory specified by the internal code from the address circuit. A character pattern format converter is provided.

[0010]

In the character pattern converter according to the present invention, when a character pattern in the dot format is input together with a character code, the character pattern in the dot format is converted into an outline format character pattern, and the character pattern is converted from the character code into an address circuit. By storing in a predetermined storage area of the character pattern memory designated by the converted internal code, the character pattern generator for character pattern processing in outline format can directly process the character pattern in dot format.

【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a character pattern memory, 3 is a conversion circuit, 4 is a 1-character buffer, 5 is an output conversion circuit, and 6 is an output device, which is the same as or equivalent to those of the conventional ones given the same reference numerals in FIG. Since it is a part, detailed description is omitted.

2 shows that when a dot-shaped character pattern is input together with a character code, the character code 7 has a function of converting the character code into an internal code designating a predetermined storage area in the character pattern memory 1. This is an address circuit different from that denoted by reference numeral 2. 8 converts the input character pattern in the dot format into an outline format character pattern, which is stored in the character pattern memory 1;
It is a character pattern format converter for storing in a storage area specified by an internal code from the address circuit 7.

Next, the operation will be described. When a character pattern in dot format is input together with a character code by input from the host computer or MT input, the address circuit 7 specifies the character code in a predetermined storage area such as an empty storage area of the character pattern memory. It is converted into an internal code and transferred to the character pattern format converter 8 together with the input dot format character pattern.

The character pattern format converter 8 converts the received dot-type character pattern into an outline-type character pattern, and a character specified by the internal code sent from the address circuit 7 together with the dot-type character pattern. It is stored in the storage area of the pattern memory 1.

On the other hand, similarly to the conventional case, the character code input alone is converted into an internal code by the address circuit 7 and then sent to the character pattern memory 1 to be designated by the internal code of the character pattern 1. Storage area
The outline type character pattern stored in advance is read. At this time, there is no difference between the character pattern outline-converted by the character pattern format converter 8 and the character pattern stored in the character pattern memory 1 in the original original outline format, and they are treated equally.

The outline type character pattern read from the character pattern memory 1 is sent to the conversion circuit 3 to be converted into a dot type character pattern, which is temporarily stored in the one-character buffer 4 on a character-by-character basis. The output conversion circuit 5 is
The dot-type character patterns are sequentially read from the 1-character buffer 4, converted into a data format for print output, and sent to the output device 6.

[0017]

As described above, according to the present invention, when a dot-type character pattern is input together with a character code, the dot-type character pattern is converted into an outline-type character pattern and the address circuit is used. Since it is configured to be stored in a predetermined storage area of the character pattern memory specified by the internal code from, it becomes possible to directly process the character pattern in dot format with the device for outline character pattern processing,
Pre-processing of converting the character pattern into outline format beforehand with a host computer etc. is not required, and processing of the external character dot font pattern in the print data is also possible.
There is an effect that a character pattern generator having excellent data compatibility can be obtained.
