Abstract

PURPOSE:To output various kinds of characters and to facilitate a change in a character font by constituting the title processor so that the character font can be registered by an image reading means. CONSTITUTION:When the reading of the character font is begun in an image reader 10, character font data is stored in an image memory 13 by relating said data to code data. After the arrangement coordinates of an output character font are set in the output image area of the image memory 13, character code data is read and stored in a RAM 15. Then, the character font data where the code data is assigned is copied to the arranged coordinates, which are retrieved and read out of the image memory 3, and set. The arrangement coordinates of the character font are updated. If unprocessed character code data does not remain in a disk memory 12, character font data is read from the image area of the image memory 13 and is outputted and printed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image processing device that displays or prints characters (including symbols and marks) using font data.

[Conventional technology]

Conventionally, in printing devices such as computers and word processors, when printing characters, font data stored in advance in a storage device such as ROM is read out according to the code data of the character to be printed, and this font data is used to print characters on the print head. The machine is designed to drive the characters and reproduce them as characters on the recording paper.

The same is true when displaying characters on the screen of a display device.

By the way, in recent years, not only standard fonts such as Koshitsuku font and Mincho font, but also so-called fonts such as calligraphy font, etc.
− There is an increasing demand for the ability to print and display in handwritten style fonts.

[Problem to be Solved by the Invention] However, in order to prepare in advance the character fonts corresponding to such a wide variety of fonts in a storage device such as a ROM, the storage capacity of the storage device becomes enormous. The problem is that it becomes extremely expensive. Furthermore, since it is common to use a writing device such as a ROM that cannot be rewritten, there is a problem in that the character font cannot be easily changed.

SUMMARY OF THE INVENTION An object of the present invention is to provide an image processing device that can output characters in a variety of fonts using a small-capacity writing/writing device, and that can easily change character fonts.

(Means for Solving the Problems) In the present invention, an image reading means for reading an arbitrary character font 1- is provided.Then, data of the read character font is associated with code data corresponding to the data, and the font data is stored. The font data is stored in the means, and desired font data from among the font data stored therein is read out using character code data corresponding to the data and outputted from the output means.

[Operation] For example, when printing in calligraphy, a calligraphy character font is read in advance by the image reading means and stored in the font data storage means in association with code data.

When printing, character code data corresponding to desired font data from among the stored font data is input, font data corresponding to the character code data is read out, and output means such as a printing device is used to print the data.

By configuring the image reading means to be able to register J: character font data, even if the storage capacity of the font data storage means is small, characters in a wide variety of fonts can be printed simply by updating the registered contents. In addition to being able to display the font in a different way, it is also extremely easy to change the font.

[Embodiment] FIG. 1 is a functional block diagram showing an embodiment of the present invention, which includes an image reading means 1, a character font data storage means 2,
Control means 3, character code data storage means 4, output means 5
The data of an arbitrary character font read by the image reading means 1 is stored in the font data storage means 2 in association with the code data (1 digit), and a keyboard, etc. (not shown) is stored at the time of document creation. When character code data is input from , it is sequentially stored in the character code data storage means 4 and transferred to the control means 3 in the order in which it was input, and code data corresponding to the character code data is assigned to the control means 3. The character font data thus obtained is read out from the character font data storage means 2 and outputted to the output means 5 as a printed output or display output.

FIG. 2 is a block diagram showing a specific embodiment of the present invention.
, has a large number of character keys for inputting characters when creating documents,
When any character key is operated, the keyboard 11 outputs the character code code corresponding to that character key, the disk memory 12 sequentially stores the input character code data, and the image reading device 10 reads the data. An image memory 13 for storing character data), an image output device 14 for printing or displaying characters, a random access memory (RAM>15, for controlling the above parts) for temporarily storing character code data, etc. It is composed of a central processing unit (CPU) 16 that performs the processing.

FIG. 3 is a flowchart showing the general operation of the above configuration, and the operation will be explained below with reference to this flowchart.

First, the image reading device 10 reads the height h and width W1 of the character font read by the image reading device 10 and the scaling factor m for printing out using the keyboard 11 or a mark sheet on which these values are written. Let's do it manually.

After storing these (correct, W, m) in the RAM 15, the CPU 16 waits for the start of reading the character font.
When the image reading device 10 starts reading the character fonts 1 to 1, the character font data is associated with the code data corresponding to the data and stored in the image memory 13.
(S2, 83). That is, as shown in FIG. 4, code data consisting of, for example, upper 16 bits and lower 16 bits is assigned to each character phono 1- such as English letters, symbols, and kana characters, and is stored in the image memory 13.
to be memorized.

Next, in the output image area 130 of the image memory 13, after setting the layout coordinates x1 and yl of the output character font as shown in FIG. Reads character code data one character at a time in the input order and stores it in RAM.
13 to be memorized. Thereafter, the character font data to which code data corresponding to the character code data stored in the RAM has been assigned is searched and read from the image memory 13, and the read character font data is placed in the arrangement set in step S4. Copy and place at coordinates x1 and yl (86.87). Next, output character font layout coordinates x1. yl is updated to xl = x1 + w yl = y1 + h (S8), and the destination 3! is stored in the disk memory 12! Check whether character code data for H remains (S9),
If there are any remaining characters, the process returns to step S5 and the conversion of unprocessed character code data to output character phono 1- is repeated. However, if no characters remain, it means that the characters input from the keyboard 11 have been converted into character font data of the arbitrary font read by the image reading device 10, so the output image area 130 of the image memory 13 The character font data stored in the font data are sequentially read out and printed out from the image output device 14. In this case, when the output magnification m is specified, the CPU 16 enlarges or reduces the character font data read from the image memory 13 according to the magnification m and outputs the data.

By making it possible to register the character font read by the image reading device 10 in association with its code data in this way, the image memory 1 that stores the font data
3 can output characters in various fonts just by updating the registered contents even if the storage capacity is small. Also, you can easily change the character font.

Note that the code data corresponding to the character font read by the image reading device 10 is stored in a part of the mark sheet on which the character font is written, and the code data is read at the same time as the character font is read to associate it with the character font. , or a method of inputting and associating character fonts from the keyboard 11 before starting to read them, or reading character fonts in the order of code data based on JIS standards, etc.
Any method such as associating code data with character fonts may be used.

(Effects of the Invention) As explained above, in the present invention, since character fonts can be registered by the image reading means, even if the capacity of the storage means for storing character font data is small, characters of various fonts can be registered. can be output as printed output or display output, and the character font can be changed extremely easily.
