Abstract

PURPOSE:To continuously print text data of an arbitrary character size with image data by providing a text controller for setting a character size, a character height, a character width, and a printing position for every character in the text data and an image controller for cutting image data developed into a dot pattern for every character and storing them into a font memory. CONSTITUTION:A text controller 7 interprets text data read from a magnetic tape 1, sets a character size, a character height, a character width, and a printing position for every character in the text data with respect to each character of the read text data, develops the dot pattern of font data of each character obtained from a font memory 9 in accordance with the aforesaid set values, and makes a printer 6 print the data. An image controller 8 reads image data from the magnetic tape 1, interprets it, and develops it to a dot pattern. The developed image data is cut per character. The dot pattern of the image data which has been cut per character is sent to the font memory 9 and stored therein. The image data stored in the font memory 9 are sequentially sent to the printer 6, and each of them is printed per character on a cut position.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device capable of printing text data and image data.

[Conventional technology]

Figure 8 shows, for example, M8310 manufactured and sold by Mitsubishi Electric Corporation.
1 is a block diagram showing a conventional printing device of the type; FIG. In the figure, reference numeral 1 denotes a magnetic tape as a storage means in which text data and image data to be printed are stored. 2 is a text controller that interprets text data read from the magnetic tape 1, and 3 is a font memory that stores font data based on dot patterns of each character to be printed. Further, reference numeral 4 denotes an image controller that interprets image data read from the can air tape 1 and develops it into a dot pattern. 5, dots and turns of each character of the text data interpreted by the text controller 2 and read out from the font memory 3 and drapery turns of the image data interpreted by the image controller 4 are superimposed and developed. This is the bitmap memory that is stored.

Reference numeral 6 denotes a printer that prints out one page of data developed in the bitmap memory 5.

Next, the operation will be explained. The text controller 2 first reads text data from the magnetic tape 1. Next, the read text data is interpreted and the font data of each character related to the text data is read out from the font memory 3, and the font data of each character is read out from the font memory 3.

The cut pattern is once developed on the bitmap memory 5. On the other hand, the image controller 4 similarly reads image data from the magnetic tape 1, interprets this image data, and develops it into dot patterns (turns).Then, the dot pattern of this image data is stored in the bitmap memory 5 as the main text data. Expand over the dot pattern of each letter.

When the text data and image data for one page are developed in the bitmap memory 5, the data is sent to the printer 6 and printed.

[Problem to be solved by the invention]

Since the conventional printing device is configured as described above, 1.
Not only is the bitmap memory 5 required to develop the dot patterns of one page's worth of text data and image data, resulting in an increase in space, but the dot patterns of each character of the text data are once bit mapped. Since it is stored in the memory 5, analog methods cannot be used to create arbitrary character sizes, and the font memory 3 must be provided with font data in the form of dot patterns of multiple sizes for each character. There were problems such as.

This invention was made to solve the above problems, and if there is one type of font data for each character,
To provide a printing device which can print text data of any character size continuously together with image data and has a small amount of node hardware.

[Failure to solve the problem]

The printing device according to the present invention includes a main body controller that interprets main text data read from a storage means and sets character size, character height, character width, and printing position for each character of the main text data; The image controller is provided with an image controller that interprets the read image data and develops it into a dot pattern, and cuts out the image data developed into the dot pattern into character units and stores them in a font memory.

[For production]

The printing device according to the present invention prints the font data of each character of the main text data read from the font memory in a character size according to the interpretation by the main text controller, and also cuts out the font data stored in the font memory into character units by the image controller. By printing image data based on the created dot pattern, hardware such as bitmap memory is no longer required, and by simply preparing one type of font data for each character in the 7-ont memory, any character size can be printed. To enable text data to be printed continuously together with image data.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, numeral 1 is a magnetic tape as a storage means, and 6 is a printer, which are parts equivalent to conventional ones.

Further, 7 is a text controller corresponding to the conventional text controller 2, which interprets the text data read from the magnetic tape 1 and determines the character size, character height, character width, and printing position for each character of the text data. Set each time.

Reference numeral 8 denotes an image controller corresponding to the conventional image controller 4, which interprets the image data read from the magnetic tape 1, develops it into a dot pattern, and cuts out the image data developed into the dot pattern into character units. . Reference numeral 9 denotes a font memory corresponding to the conventional 7-ont memory 3, which stores font data based on a dot pattern of a predetermined size for each character to be printed, and also stores image data dots cut out character by character by the image controller 8. Memorize patterns.

Next, the operation will be explained. The magnetic tape 1 stores text data and image data, and the text controller 7 interprets the text data read from the magnetic tape 1. That is, for each character of the read body data, the character size, character height, character width and its printing position are set for each character of the body data, and the dot pattern of the font data of each character obtained from the font memory 9 is set. is expanded accordingly and printed by the printer 6.

FIG. 2 is an explanatory diagram showing an example of the printing. In the example shown in the figure, A and D are printed in bold (and B and C are printed in small size). A-D as shown in
Each character is stored as font data using a predetermined dot pattern of the same size.

The image controller 8 also reads image data from the magnetic tape 1, interprets it, and develops it into a dot pattern. Here, even a single line of image data developed into this dot pattern covers the entire printing paper, and cannot be printed by the printer 6, which prints character by character. Therefore, the image controller 8 cuts out the image data developed into the dot pattern into character units as shown in FIG. In FIG. 4, a grid for cutting out image data in character units and its coordinate numbers are also shown. The dot pattern of the image data cut out character by character in this way is sent to the font memory 9 and stored therein.

FIG. 5 is an explanatory diagram showing an example of a dot pattern of image data cut out in units of characters, and illustrates an example of a dot pattern of image data cut out from coordinate numbers 30-4 and 30-5 in FIG. .

The image data stored in the font memory 9 in this manner is sequentially sent to the printer 6, and is printed character by character at each cut out position.

FIG. 6 shows an example of printing when the image data thus printed and the text data described above are printed on the same sheet of paper.

In the above embodiment, the case where there is one set of image controllers 8 has been described, but as shown in FIG. By switching and using them as necessary, it is possible to obtain a variety of prints.

[Effects of the Invention] As described above, according to the present invention, the font data of each character of the text data read from the font memory is printed according to the interpretation of the text controller, and the font data is stored in the font memory by the image controller.
Since it is configured to print image data based on dot patterns cut out for each character, hardware such as bitmap memory is not required, and only one type of font data is prepared in the font memory for each character. This has the effect of providing a printing device that can continuously print text data of any character size together with image data.
