Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a character processing method for enabling characters displayed on a display means in a certain font to be redisplayed in another font. It is something.

[Prior Art] When a character processing device is used, characters are generally input using an input means such as a keyboard, a text is created while displaying the characters on a display means, and the created text is then displayed. This includes work such as printing on a printing device.

In such a character processing device, it may be necessary to change the form of characters, that is, the font. For example, you may need to replace the read-only memory, or so-called ROM device, that contains the font pattern you want to change, or send the font pattern you want to change from an external disk device to the character generator of the character processing device, or It was necessary to change the font pattern of the character generator character by character using a specific method.

On the other hand, when printing, before printing in the font desired by the operator (for example, Mincho font or Gossik font), the amount of recording media and recording materials consumed, and the amount of time spent on printing must be considered. In order to reduce this, it is desirable that the operator be able to reliably know the actual printing condition in advance and decide on the font before printing.

[Problems to be Solved by the Invention] An object of the present invention is to provide a character processing method that allows characters displayed in a certain font to be easily replaced with another font and displayed with high quality. There is a particular thing.

[Means for Solving the Problems] To this end, the present invention provides: a first storage means for storing a character pattern in a first typeface; a first storage means for storing a character pattern in a first typeface; and a second storage means for storing a character pattern in a second font different from the first font, and transmits the character pattern from the first storage means or the second storage means based on the character information. , displaying a character pattern in the first font, or displaying a character pattern in a second font that is the same as the character pattern expressed in the first font and is different from the first font. In the character processing method, a character pattern is transferred from the first storage means based on character information, and when an instruction to switch the font is received when the character pattern is already displayed in the first font, the above-mentioned In order to display the character pattern displayed in the first font in the second font, the character pattern from the second storage means is transferred based on the character information; In place of the character pattern of the first font, a character pattern of the second font representing the same character as the character pattern represented by the first font is displayed.

[Operation] In the present invention, for example, when the operator instructs to switch fonts as desired, characters in the first font are displayed in place of characters in the second font. That is,
Characters displayed on the display means in a certain font can be easily redisplayed in another font with high quality, so the ease and reliability of font determination can be improved.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment of a character processing device to which the present invention is applied, in which 1 is a microprocessor, and 2 is an address bus, which transmits address signals that indicate the components to be controlled by the microprocessor 1. Forward. A control bus 3 transfers control signals to each component to be controlled by the microprocessor 1. A data bus 4 transfers data between each component. Reference numeral 5 denotes a read-only memory, or so-called ROM, which stores programs corresponding to control procedures by the microprocessor 1, which will be described later with reference to FIG. 4, and also stores, for example, a Mincho font 6 and a Gothic font 7. There is.

Reference numeral 8 denotes a random access memory, ie, a so-called RAM, which can be written in a 1-word, 16-bit configuration, and is used to temporarily store data from each component. A keyboard 9 has various key groups for inputting various data and giving instructions to the character processing device.

Reference numeral 10 denotes a cursor register, which is a memory for writing data at the cursor position and reading data at the cursor position. Reference numeral 11 denotes a data buffer, which is a memory for storing text information inputted by the keyboard 9. 12 is
The CRT controller 13 is a display device that can be configured using a cathode ray tube (CRT), etc., and in this example,
It uses CRT. The CRT controller 12 is
The cursor is moved to the display position on the CRT 13 corresponding to the address stored in the cursor register 10 and displayed, and a display pattern based on the character code signal stored in the buffer memory 11 is displayed.
Display on CRT13. The buffer memory 11 can also be used as a refresh memory for the CRT 13, and can be freely read and written by the microprocessor 1. In this example, 14 is a character generator composed of a RAM whose memory contents can be rewritten, and generates character signals such as characters and cursors to be displayed on the CRT 13 according to the information developed in the memory area. It is something. This character generator 14 is
For example, character information having a 16×16 bit structure can be generated. As is clear from the figure,
There are a plurality of fonts, fonts 6 and 7, and this character generator is commonly used by them.

Figure 2 shows a specific example of the keyboard 9, where 9A is a group of various keys such as character keys and function keys for character processing, 9M is a conversion key for converting character form to Mincho typeface, and 9G is a character form. This is the conversion key to convert font to Gothic font.

An outline of the operation of the embodiment with such a configuration is described in the third section.
This will be explained with reference to Figures A and B.

First, when the power is turned on, the contents of the Mincho font 6 are transferred to the character generator 14, and the cursor 15 is displayed on the CRT 13 at the top left corner. Next, when you enter characters etc. from the key group 9A of the keyboard 9, the characters etc.
A cursor 15 is output on the CRT 13 at the displayed position, and the cursor 15 advances one by one to the right as characters are input. Note that the input/output control described above can be easily realized using conventional technology.

Since the Mincho font 6 is transferred to the character radiator 14, all characters output at this time are in Mincho font, as shown in Figure 3A.
They are displayed on the CRT 13, but if you want to convert them to Gothic font, press the Gothic font conversion key 9G and the Gothic font 7 will be transferred to the character generator 14, and the characters displayed on the CRT 13 will be As shown in FIG. 3B, all are converted to Gothic font. Furthermore, if you want to return to the Mincho font again, press the Mincho font conversion key 9M.
Mincho font 6 is character generator 1
4 and the characters displayed on the CRT 13 are all returned to Mincho font, as shown in FIG. 3A.

Note that the present invention may be applied to a system composed of a plurality of devices, or may be applied to a device composed of one device. Alternatively, it goes without saying that the present invention can also be applied to a case where the effects of the present invention are achieved by supplying a program as shown in the flowchart of FIG. 4 to a system or device.

Next, the processing operation of the present invention will be explained with reference to the flowchart of FIG.

First, when the power is turned on, the Mincho font 6 is transferred to the character generator 14 in process 1. In process 2, keys 9A, 9A and 9
If any key is input, it is determined in step 3 whether it is the Mincho font conversion key 9M, the Gothic font conversion key 9G, or a key 9A for other characters. if,
If the input key is the Mincho font conversion key 9M, proceed to process 4, and transfer the Mincho font 6 to the character generator, and if the input key is the Gothic font conversion key 9G, proceed to process 5. Go ahead and change the Gothic font 7 to the character generator 14.
Transfer to. Alternatively, if the input key is neither the Mincho font conversion key 9M nor the Gothic font conversion key 9G, the process proceeds to step 6, where normal character processing is performed. When such processing is completed, the process returns to the key input waiting state of process 2.

In the above embodiment, the fonts of the characters are two types, Mincho font and Gothic font, but in addition to these, for example, italic fonts, italic fonts for English letters, etc. may be added and memorized, and the fonts of the characters can be changed to each other. It is also easy to configure the system to convert .

[Effects of the Invention] As explained above, according to the present invention, characters displayed in a certain font can be easily redisplayed with high quality characters in another font. It is possible to improve the ease and certainty of decision making and, in turn, improve the operability of the character processing device.
