Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention registers external characters such as special fonts that computers do not normally have or fonts uniquely defined by the user in a font pattern with a predetermined dot configuration. This relates to a non-standard character registration system.

[Conventional technology]

Figure 4 shows, for example, “Japanese Concurrent CP/Ms6tM
This is a block diagram showing a conventional external character registration system shown in the user's manual MULT116. A keyboard device 5 is connected to the computer body 1 by a cord 4, and a mouse 5 is also connected to the computer main body 1 by a cord 6.

Next, the operation will be explained. When registering external characters, a font table is first displayed on the display device 2. If this font table is for a font pattern to be displayed on the display device 2, it has a dot configuration of, for example, 16 dots x 16 dots, and if it is for a font pattern for printing, it has a dot configuration of, for example, 24 dots x 24 dots. The 0 work sound, which is composed of dots, is created by sequentially specifying each dot in this font table using the cursor movement keys on the keyboard device 3 or the mouse 5, and then using the specified dots in the external character registration design document. In this way, the font pattern of the external character is registered based on the significance/insignificance of each dot in the font table.

[Problem to be solved by the invention]

Since the conventional custom character registration system is configured as described above, it is necessary to create a custom character registration design document in advance with a predetermined dot configuration for the custom characters to be registered.
In addition, because there is a slight discrepancy between the external characters displayed in the font table on the display device 2 and the external characters that are actually displayed or printed, it is possible to incorrectly set the significance/insignificance of each dot in the font table. There were problems such as specifying the

This invention was made to solve the above-mentioned problems, and it simplifies the registration of external characters. The purpose is to obtain a system for registering external characters that can be used to make mistakes.

[Means to solve the problem]

The custom character registration system according to the present invention divides a predetermined range of custom character data read by an image reader vertically and horizontally according to the dot configuration of a font table, and divides the data into each unit of data. A non-standard character is registered by determining whether bits are significant or not, and when the number of significant bits reaches a predetermined threshold value, a dot corresponding to the unit data is made significant.

[For production]

The custom character registration system of the present invention reads a custom character to be registered using an image reader, divides a predetermined range of read data of the custom characters vertically and horizontally according to the dot configuration of a font table, and divides each created unit data into The significance/insignificance of each bit of the private character data composing the data is determined, the number of significant bits is counted, and the dot corresponding to the unit data in the font table is set when the counted value reaches a predetermined threshold. Significant if

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, l is the computer main body, 2 is the display device,
3 is a keyboard device, 4.6 is a code, and 5 is a mouse, which are the same or equivalent parts to those of the conventional device denoted by the same reference numerals in FIG. 4, and detailed explanations thereof will be omitted. Further, 7 is an image reader connected to the computer body 1 by a cord 8.

Next, the operation will be explained. Here, FIGS. 2(a) and 2(a) are flowcharts showing an example of the operating procedure, and FIG. 3 is an explanatory diagram showing the concept of the external character registration process.

First, the image reader 7 reads, for example, A4 size (
The external characters to be registered drawn on the paper (210mm x 292mi+) are read, the external character data is input into the computer main body 1, and the font table pointer is set (step 5TI). At this time, the image reader 7 For example, the dot density of 16 dots/1+n
If m, external character data of 3360 bits x 4672 bits is input into the main body of the computer. Next, a predetermined range of the input external character data, for example, 210 mm x 210 mm
The conversion data indicated by 10 in FIG. 3 is generated by specifying the square range (step 5T2). Therefore, this conversion data has a structure of 3360 bits x 3360 bits.

Next, according to the dot configuration of the font table 11 of, for example, 16 dots x 16 dots, the converted data 10 is divided vertically and horizontally into 16 parts to create a font pattern for display on the display device 21\, and is divided into 210 bits x 2 pieces.
Create 10-bit unit data 12 (step 5T)
3) Next, it is determined whether each bit of the external character data constituting the unit data 12 is significant or insignificant, and the number of significant bits is counted (step 5T4).

Next, the count value of the bits determined to be significant is set to a predetermined threshold, for example, the total number of bits of the unit data 12 210×21
It is determined whether the number of significant bits of the unit data 12 has reached 22,050 bits, which is half of 0=44,100 bits (step 5T5). As a result, if the number of significant bits of the unit data 12 has reached the threshold value, The dot 13 corresponding to the unit data 12 is made significant (step 5T6). The number of times of processing in steps ST4 and subsequent steps is the total number of dots in the font table 11,
That is, the process is repeatedly executed until it is detected that the number reaches 16X16=256 (step 5T7). As a result, a font pattern of 16 dots x 16 dots for display on the display device 2 of the external character to be registered is completed.

Next, for example, 2
According to the dot configuration of the font table of 4 dots x 24 dots, the converted data is divided vertically and horizontally into 24 parts to create unit data of 140 bits x 140 pixels (step 5T8).

Next, it is determined whether each focus of the external character data constituting the unit data is significant or insignificant, and the number of significant bits is counted (step 5T9).
). Next, the count value of the bits determined to be significant is set to a predetermined threshold, for example, the total number of bits of unit data 140x1.
A determination is made as to whether 9800 bits, which is half of 40=19600 bits, has been reached (step 5T10). As a result of the determination, if the number of significant bits of the unit data has reached the threshold value, the dot corresponding to the unit data in the font table is made significant (step 5TII). The number of processing steps from step ST9 onwards is the total number of dots in the font table,
That is, the process is repeatedly executed until it is detected that the number reaches 24×24=576 (step 5T12). As a result, a 24 dot x 24 dot printing font pattern of the external character to be registered is completed.

Next, both the completed display and print font patterns are displayed on the display device 2 in order to prompt the operator to judge whether registration is possible or not (step 5T13). Next, the judgment result inputted by the operator as to whether or not registration is possible is judged (step ST'i4), and if the judgment result is a registered town, the registration process for both of the completed font patterns is executed. (Step 5T15). Furthermore, if the operator's judgment is that registration is not possible, both completed font patterns are cleared (step 5T16).

In the above embodiment, the external characters to be registered drawn on A4 paper are read by the image reader 7, and the read external character data is automatically converted into square conversion data. It is also possible to use a sheet of paper with a size of 1, and if the external characters to be registered are drawn on a square sheet of paper, the entire range of external character data may be used as the conversion data.

Further, the external character data read by the image reader 7 is displayed on the display device 2, and the range to be registered is specified using the mouse 5, so that only the external character data within the specified range is converted into conversion data. (The dot density of the image reader 7 is also 16 dots/I II+tn
Not only 8 dots, /1+nm4 dots/l
It may be mm, etc.

Further, in the above embodiment, the font table is a square one with the same number of vertical and horizontal dots, but it may be a rectangular one with a different number of vertical and horizontal dots. In that case, the conversion data is 14% of the font table. The ratio is converted to be equal to the column width ratio of this font table.

In any of these cases, the same effects as in the above embodiments can be achieved.

〔Effect of the invention〕

As described above, according to the present invention, a predetermined range of external character data read by an image reader is divided vertically and horizontally according to the dot configuration of the font table to create unit data, and is configured for each unit data. It determines the significance/insignificance of each bit of the specified character data and counts the number of significant bits, and if the counted value reaches a predetermined threshold, the dot in the font table corresponding to that unit data is Since the system is configured to be significant, a non-standard character registration system is obtained in which non-standard characters can be registered easily and without errors, and an operator is freed from the trouble of creating a non-standard character registration design document.
