Abstract

PURPOSE:To easily generate the font of optional characters by easy operation by specifying the range of the size of the font of input characters and symbols and storing the font of the characters and symbols whose range is specified as an external character of the font of one character. CONSTITUTION:This processor is equipped with an input means 101 for inputting characters and symbols, a range means 102 for specifying the range of the size of the font of the input characters and symbols, and a storage means 103 for storing the font of the characters and symbols whose range is specified as the external character of the font of one character. Then the range of a normal character string is specified and a command for conversion to the external character is inputted, thus registering the font as the external character. Consequently, the optional character string is registered as external characters, so characters which are already stored in a storage device are put together to generate an optional character by an operator.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character processing device that allows a user to arbitrarily create external characters.

[Prior Art] In conventional character processing devices, there are cases where it is desired to insert multiple characters into a font of the normal size of one character, as shown in FIG. 8, instead of using a font of a normally used size. . In FIG. 8, the broken line only indicates the size of the font, and does not necessarily exist as a font. Such characters may be prepared in advance in the character processing device, but this does not cover all the fonts the user needs, and if the font the user wants is not available, the user can Since I had to create a font, I had to enter all the dots that make up the font.

[Problem to be solved by the invention 1 As mentioned above, when a user needs a font like the one shown in Figure 8, he has to input all the constituent dots, which requires considerable effort and time. There was a problem.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and provide a character processing device that can create a font of any character with simple operations.

[Means for Solving the Problem] In order to achieve such an object, the present invention specifies an input means for inputting characters and symbols and a range indicating the font size of the input characters and symbols. The range specification means and the font of the characters and symbols specified in the range are set to 1.
and storage means for storing characters as external characters of a font.

[Function] In the present invention, a font can be registered as a non-standard character by specifying a range of normal character strings and inputting for conversion to a non-standard character.

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

As shown in FIG. 1, the character processing device according to the present invention includes an input means 101 for inputting characters and symbols, a range means 102 for specifying a range indicating the font size of the input characters and symbols, A storage means 103 is provided for storing a font of characters and symbols specified in a range as external characters of a single character font.

FIG. 2 shows a system configuration diagram of an embodiment of the present invention. Here, 2A is a central processing unit (hereinafter referred to as CP) that controls this system.
(abbreviated as U). 2B is a storage device, which has a workpiece 2C necessary for operating the system and a custom character area 2D for storing custom characters.

The work 2C has a range specification flag 11S which becomes 1 during range specification, a range specification start address IIs8, and a range end address HEA.

2E is a display device such as a CART (cathode ray tube), which displays characters and symbols. 2F is a character generator (CG), which stores fonts used for display or printing.

2G is a keyboard which is an input device for inputting characters and symbols.

FIG. 3 shows a keyboard 2G which is an input device.

Here, 3A is a key for specifying a range. 3B is a custom character conversion key that serves as a trigger for converting characters specified in the range by the key 3^. 3C is a cursor movement key group, which moves a cursor indicating an input position.

FIG. 4 shows detailed contents of the external character area 2D. In this embodiment, the number of external characters is eight. Register the 8 external characters with the numeric code 4B that they indicate. 4A is the index of the external character (
GI), prepare one byte, make the MSB correspond to the code 8 external character, and the LSB to the code 1 external character, and determine whether the corresponding external character exists or not depending on whether the corresponding bit is 1 or O. do. Here, 0 indicates that there is no external character, and 1 indicates that the external character is present.

The processing procedure of the embodiment of the present invention will be explained according to the flowchart shown in FIG.

First, in step S1, key input is performed from the keyboard 2E.

In steps S2 and S3, the type of key input is determined. In step S2, range specification key 3
In step S3, it is determined whether the external character conversion key 3B is A or not.

If it is determined in step S2 that the key is a range specification key, the process proceeds to step S5. If it is determined in step S3 that the key is a private character conversion key, the process proceeds to step S4. If neither of these keys is available,
Proceed to step S8 to perform other processing. The process of moving the cursor when the cursor movement key 3C is input is also included in the other processes in step S8.

In step S2, when it is determined that the key input in step S1 is the range designation key 3A, the process proceeds to step S5, and it is determined whether the range designation flag Its is 0 or not.

When H5 is 0 in step S5, step S6
Go to step 1 and set the range specifying flag H5 to 1. The process then proceeds to step S7, where the current cursor position is stored in the range start address USA, and the process again proceeds to the key input process of step S1.

If the range specification flag H5 is not 0 in step S5, then the range is currently being specified, so the range specification flag H5 is set to 0. The process then proceeds to step 510, where the current cursor position is stored in the range end address HEA, and the process proceeds to key input processing in step St. Before the range designation key 3A is pressed twice, the cursor movement key 3C is pressed to designate the character block for which the range is to be designated.

To explain using the example shown in Fig. 6, when the cursor is at position 6a, press range designation key 3^ to start range designation, press the cursor key to move the cursor to position 6b, and then press range designation key 3A. Press to finish specifying the range. Here, the position of 6a is stored in the range start address 1 (SA), and the position of 6b is stored in the range end address HEA.

The external character conversion process in step S5 in FIG. 5 will be explained in detail according to the flowchart shown in FIG.

First, in step Sll, it is checked whether there is any free space for external characters. This can be easily checked by simply checking whether there is an O in the bit of the private character index (Gl) 4^. If all the private character indexes (Gl) are 1, there is no free space for the private characters, so the process proceeds to step 515, displays an error message to the effect that there is no free space for private characters on the display device 2E, and exits from this private character conversion process. .

The external character index (Gl) is determined in step Sll.
) If there is a 0 in any bit of 4A, there is a free space for a private character and registration of a private character is possible, so the process proceeds to step 512 and subsequent steps.

In step S12, font development of characters in the area indicated by the range start address and range end address is performed based on the data stored in CG2F. Thereafter, the process proceeds to step S13, where data compression is performed on the expanded font of the designated block to the size of the external character. Then, in step 514, the compressed data is registered in the free private character area, the registered data is registered,
The private character index (Gl) corresponding to the registered private character
)4^ bit to 1 and exits the external character conversion process.

To explain using the example shown in FIG. 6, after specifying the range in blocks 6a to 6b, the user presses the external character conversion key to perform the external character conversion process. Here, 6c is a blank code, and although no characters have been input, it is an index representing the position of a character, so it is treated as a space when developing a font. If the font of the external characters is 32 dots x 32 dots, in the example shown in Fig. 6, there will be 2 characters vertically and 2 characters horizontally, so the expanded dots will be 64 dots x 64 dots. When registering a non-standard character, this expanded dot is reduced to a size of 174. Then, the reduced data is stored in the private character free area. Now, assuming that the custom character area for code 7 shown in FIG. 4 is empty, the font data shown in FIG. 8 is stored as a custom character in the area 4B.

The above is an explanation of the embodiment, but if the operator inputs a code for registering a custom character before entering the custom character conversion process in step S4 in FIG. 5, it can be registered as a custom character in any code of the operator. This makes it more convenient for the operator.

[Effects of the Invention] As explained above, in the present invention, any character string can be registered as a custom character, so the operator can create any character string by combining characters already stored in the storage device. Since characters can be created, it has the effect of enriching the expression of documents.
