Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-font display device using a screen definition body. In an input / output processing device for inputting / outputting data corresponding to a screen, a display character (item character) of each item, its display attribute, and an input / output field corresponding to each item are defined by a screen definition body.

In such an input / output processing device, as the number of items in one screen increases, it becomes more inconvenient to operate such that it takes time to visually identify an item character of interest or an input / output character. A screen layout that makes important items easy to see is required.

[0003]

2. Description of the Related Art FIG. 5 is an explanatory view of a conventional example and shows an example of a device for performing input / output processing corresponding to a screen.

In FIG. 5, the screen definition body 1 is composed of an item display field information table 3 and an input / output field information table 2, and the item display field information table 3 has item display fields ,. Display attributes such as fixed item characters and their display positions and colors are defined, and the input / output field information table 3 displays the attributes (display position) of fields for displaying data input / output corresponding to each item. , Number of digits, etc.) are defined and are filed for each input / output screen.

When an input / output screen is designated and the screen is opened, the screen definition body 1 corresponding to the input / output screen is referenced, and first, based on the item display field information table 3, "employee number," name The data of item characters such as “” and the ruled line frame data of the input / output field are expanded in the logical screen memory 8 together with the display attributes, and are dot expanded in the display screen memory 6 by the display control unit 5. At this time, the display control unit 5 refers to the character pattern memory 4 by the character code and expands the character pattern in the display screen memory 6. As a result, the contents of the display screen memory 6 are scanned and read out and displayed on the display screen 7.

In this state, a cursor is displayed at the beginning of the input / output field (the field for inputting data is referred to as an input field, and the field to which the processing result is output is also referred to as an output field). Enter the data from. If the input is successful, the cursor moves in the order of the input fields to indicate the next input field.

The data input / output to / from the input / output field is stored in a memory (not shown) in correspondence with the items, and is edited on the logical screen developed in the logical screen memory 8 and displayed together with the item characters. .

[0008]

In the input / output processing device using the screen definition body 1 described above, the item characters and the input / output characters are fixed character patterns, for example, "Mincho type".
The size of one input / output screen (hereinafter referred to as a window) was determined based on the size of the character pattern.

Then, the display position of each item is designated in the screen definition body 1, and an input / output screen as shown in the display screen 7 shown in FIG. 5 is displayed. Item characters like this,
The display position, size, etc. of the input / output field are determined by the columns and lines based on the size of the character font for screen management, but with such a uniform screen layout, if the number of items increases However, there is a problem that visual identification becomes difficult and operability deteriorates.

In view of the above problems, it is an object of the present invention to provide a multi-font display device capable of designating a font on a field-by-field basis.

[0011]

In order to achieve the above object, the multi-font display device of the present invention, as shown in the principle diagram of the present invention of FIG. 1, (1) displays a typeface of display characters in predetermined field units. It is configured to have a designated screen definition body 30 and a display control section 31 for displaying a character in the field by referring to the screen definition body 30 and displaying in a typeface designated for the field. (2) In the above (1), the predetermined field unit is an item display field and a corresponding input / output field. (3) In (1) or (2) above, the typeface designation is configured to include designation of character size, character decoration method, presence / absence of inclination, and character pitch. (4) In (1) or (2) or (3) above, the window size is calculated from the number of columns representing the field size, number of lines, line spacing, character pitch, and font size. A unit is provided so that the display characters of each field are allocated and displayed at predetermined positions in the calculated window.

[0012]

[Action]

(1) Screen definition object that defines each field on the screen in Figure 1.
In 30, the font of the display character is designated for each predetermined field. When performing character display in each field, the display control unit 31 refers to the screen definition body 30 to refer to display attributes and the like, but simultaneously refers to the typeface and displays in that typeface.

As a result, the display characters of one field can be displayed in a typeface different from those of other fields,
Differentiating the typeface makes it easier to visually identify important items. (2) In (1) above, the predetermined field unit is an input / output field corresponding to the item display field, and the screen definition body 30 specifies to display these in the same typeface. As a result, the item characters and the input / output characters corresponding to the items are displayed in the same typeface, so that it is possible to achieve item display that is easier to visually identify. (3) In (1) or (2) above, in addition to font designations such as "Mincho,""Gothic," font type, character size, character modification method (character thickness, serif status) Etc.), whether or not there is an inclination, and the character pitch can be specified. As a result, it is possible to further differentiate characters between items. (4) In (1), (2), or (3) above, calculate the number of pixels in one line and one digit from the line spacing, character pitch, and size of the typeface. A window size calculation unit for calculating the size of the display window from the head position and the like is provided. The display control unit 31 displays the display characters of each field at the predetermined line column position in the calculated window based on the display position defined by the screen definition body 30.

As a result, even if an enlarged character or a font having a different size, such as "textbook", is adopted, it is not necessary to change the display position information such as the digits and lines in the screen definition body 30. Display management becomes easy.

As described above, since the typeface can be specified for each field of the screen definition body 30, the display of an item can be differentiated from other items, and even if the number of items increases, the visual recognition is possible. And the operability, that is, the visual confirmation of data and the input operation become easier.

[0016]

FIG. 2 is a block diagram of an embodiment, FIG. 3 is an explanatory view of changing a window size, and FIG. 4 is a flow chart of display control.

In this embodiment, when opening the input / output screen, all the items in the screen definition are referenced, and the typeface with the largest character size among the designated typefaces is extracted and set to 1
An example is shown in which one row of one digit is determined and the size of one row and one digit is applied to all fields to set the window size. It should be noted that the display characters of each item, that is, the item characters corresponding to the input / output characters are displayed in the same typeface.
Sans serif, fixed pitch, no inclination, etc.

In FIG. 2, numeral 11 is a logical screen memory in which item character information and input / output character information based on the screen definition body 13 are expanded. This character information is composed of a character code, a display position, a typeface table pointer, and the like.

Reference numeral 12 denotes a typeface table, which is a character font, a character pitch (variable pitch that changes the pitch depending on the character width / fixed pitch), and a serif state of the character (for example, the horizontal bar at the top of J is called "beard", with beard). Is specified as serif, and beardless is specified as sans serif), character thickness (thin font, bold font), character inclination (tilt angle for Japanese, Roman letters and italic for English letters, etc.) are stored. Specified by the table pointer.

Since the object of the present invention is to differentiate between items, for example, fonts that can be distinguished at first glance also regarding fonts, for example, general characters (Mincho) / cursive type. It is desirable to select.

A screen definition body 13 is a file in which the item display field information table 15 and the input / output field information table 14 are correspondingly filed, and are expanded and referred to in a main memory (not shown) when the screen is opened. .

Here, the item display field information table
Reference numeral 15 is a set of display information of item names (item characters). In each item information, ..., a font table pointer is stored together with display attributes such as item characters, display positions, colors, etc. . This pointer is composed of a plurality of pointers (addresses in the table) for designating the above-mentioned typeface, and the typeface such as whether the character pitch is fixed or variable. With this pointer, for example, "Gothic",
If you specify 1.2 times magnification and 30 degrees of inclination,
Is displayed like an item character on the display screen 7.
It should be noted that, instead of individually designating, a typeface of a desirable combination that can be identified in comparison with a normal typeface is set as one typeface, and alphabetic characters, Japanese characters, numbers, etc. are prepared and designated in the typeface table 12, respectively. Good.

The input / output field information table 14 defines an input / output field corresponding to item information here. When displaying the data input / output in this field, refer to the item display field information table 15. Then, the font table pointer is acquired and displayed in the same font as the item character. As a method to specify this same typeface,
There is also a method of storing the same typeface table pointer in the input / output field information table 14, and a method of handling the same item as the item character when incorporating the input / output character in the logical screen, as described later.

Reference numeral 18 is font information, which stores the number of pixels in one line and one digit of the font used. When the line pitch is fixed and the input / output field frame is displayed by ruled lines, the number of pixels corresponding to that is incorporated into the number of pixels in one line.
In the case of the character spacing, it is incorporated in the number of digit pixels, or the ruled line segment is determined separately for one character, for example.

A window size calculator 17 searches the screen definition body 13 when the screen is opened, finds the largest typeface out of the typefaces designated by the screen definition body 13,
The window size is calculated by using the size of the typeface as one line and one digit for all fields. Then, using this window size as a reference, each character is displayed using the line and column position specified in the screen definition body 13. 3 (1) shows the conventional basic size, and FIG. 3 (2) shows the window size when double-width characters are specified, and the display characters of other items are , Rows and columns of enlarged characters are used, and the pattern is developed at a predetermined position within the one character.

Reference numeral 21 denotes a display control unit which, based on the screen definition body 13, inputs / outputs character information such as item character information, input data input / output from a keyboard (not shown), output data of processing results and the like to the logical screen memory 11. The character pattern memory 19 is expanded based on the expanded information, and the character pattern is expanded in the display screen memory 6 and is read by scanning and displayed on the display screen 7. At this time, the typeface table pointer is also stored in the logical screen. As described above, actually, the font is specified only for the item to be differentiated, and when the font is not specified, the normal basic font for the font of the character pattern memory 19 is referred to. When the font is designated, the switching unit 20 switches the character pattern memory 19 to that for the corresponding font and develops the pattern.

Reference numeral 22 denotes a modification section which performs enlarging / reducing of characters and enlarging / reducing the character pattern obtained from the character pattern memory 19 when the character thickness is designated. Also, if the character thickness, character decoration such as outline, variable pitch, and inclination are specified, this is also processed here. It should be noted that instead of performing modification processing from a basic character pattern such as bold characters and serifs, a pattern may be registered in the character pattern memory 19. Reference numeral 16 denotes a central processing unit CPU, which controls each of the above-mentioned units to reconsider display control.

With the above configuration, the display operation shown in FIG. 4 is performed. (1) When an input / output screen is specified and the screen is opened, the logical screen is expanded in the logical screen memory 11 by sequentially referring to each item of the corresponding screen definition body 13. At this time, the typeface table pointer and the typeface application end code are also described at the end of the character string along with the character code and display position. For items that have no description, use the normal basic typeface. (2) At this point, the window size calculation unit 17 extracts the largest character from the typefaces used, based on the font information 18, and sets the 1-row 1-digit size.
At this time, the line spacing and the like are also incorporated. (3) The window size is calculated based on the calculated 1-row 1-digit size. Normally, the window size in the basic typeface is calculated and set, so the size ratio of one line and one digit is calculated. The window size is used for window processing on the display screen. (4) Then, the display process is started with reference to the logical screen memory 11. (5) The logical screen of the input / output screen is expanded in the logical screen memory 11 for each display target item, and the character pattern is expanded in the display screen memory 6 while referring to the character pattern memory 19. At this time, if there is a description of the typeface table pointer, the typeface table 12 is referenced, and if it is necessary to switch the character pattern memory 19, the switching unit 20 is instructed to switch and develop the character pattern. If there is an enlargement designation or the like, the character pattern is not switched, and the modification unit 22 performs an enlargement process or the like. (6) When the display of all the item characters is completed, it waits for data input / output, and each time data is input / output, it is edited on the logical screen and expanded into a character pattern. This input / output character is inserted between the typeface table pointer designation and the end code of the corresponding item in the logical screen so that it is displayed in the typeface of the corresponding item.

As described above, in the input / output processing device that displays the input / output screen based on the screen definition structure, since the typeface can be specified in the screen definition structure in units of items, character display between items can be performed by a simple method. Differentiation can be realized and it is easy to identify at first glance, so that operability is improved.

[0030]

As described above, the present invention provides a method of designating a typeface for each item of the screen definition type as a simple method of changing the typeface of a specific item and displaying it. Since the specific item can be easily displayed in a typeface different from other items, it is possible to solve the conventional problem that it is difficult to identify when the number of items is large and improve the operability.
