In FIG. 1, a command character code storage unit 1 stores a code of a display character and a code of a command designating its display mode as shown in FIG. Specific examples of the display mode will be described later, but there are, for example, flow display, blinking display, reverse display, flash display, spot display, and a combination display thereof. The reading unit 2 appropriately processes each unit from the command / character code storage unit 1 (for example, 2 bytes each).
A code is read out, and a large number of code groups in which a plurality of display character codes and command codes are combined are stored in sequence in the command character code storage unit 1. When these are read to the end,
Reading is repeated from the beginning again. The display data processing unit 4 has a display character code / data processing routine corresponding to each display mode, and the command analysis unit 3 determines whether the code read by the reading unit 2 is a command or a display character. When it is a command, the command is analyzed and the display data processing unit 4 is instructed to start a predetermined code / data processing routine. The character generator 5 stores the pattern corresponding to the code of the display character, and the display pattern storage unit 6 stores the pattern of the character generator 5 in which the display character is expanded according to the display mode. The display unit 7 has a display screen in which display elements are arranged in a matrix, and the display pattern is read out from the display pattern storage unit 6 and displayed in the display mode designated here. In the present invention, the display pattern storage unit is provided with a plurality of pattern storage areas and is configured to display various types of display on the display unit via the combination circuit. This point will be described later in detail.

In each code / data processing routine of the display data processing unit 4, the display character group to be processed is determined, the code of the display character group is read from the command / character code storage unit 1 through the reading unit 2, and the code Based on the above, the pattern is developed with reference to the character generator 5 and stored in the display pattern storage unit 6. In the pattern expansion processing, for example, in the case of a flow display command, the pattern data in the display area of the display pattern storage unit 6 (that area in the case of a flow command of only a partial area) is shifted line by line in the specified direction. After that, a new display pattern (including a blank) is written. The second is the hardware configuration example of the system as described above.
It is a figure. In FIG. 2, main memories 8 and 10 store code / data processing routines and other control programs and character generators, and also provide a storage area for display patterns, a command / character code storage area, and a work area. It is a thing. Keyboard 11
Is for inputting characters, symbols, figures, commands, etc., and the monitor 12 uses the keyboard 11 for editing input.
It is used when confirming more input characters, symbols, figures, etc., or when confirming input commands, display character data, etc. without displaying them on the display device 13. The display device 13 displays a message or information including characters, symbols and figures on a display screen in which display elements are arranged in a matrix. The control device 9 executes a code / data processing routine and other control programs, interprets characters, symbols, figures, commands, etc. input from the keyboard 11 and performs processing such as display thereof. The command character code shown in FIG. 1 is input from the keyboard 11 and stored in a specific area of the main memory 8 or 10, but it is possible to write it in the ROM in advance so that it can be exchanged, or for editing input. It is also possible to prepare a storage area for the above and a storage area for the display and to separately edit and input to the storage area for the edit input while displaying the contents of the storage area for the display. Further, in the edit input process, for example, an edit menu may be stored in the external memory 1 and the edit menu may be displayed on the monitor 12.

Next, a command for instructing a display mode, an example of specifying a display character, and an example of expanding a display pattern will be described.

FIG. 3 (a) shows an example in which the display character "This week's bestseller" is sent out one character at a time, and the display character "this week's bestseller" is followed by the command "← 1 mod". Is specified. FIG. 4A shows how the display pattern is developed by this command character code group. In Fig. 4 (a), "This week's"
It shows that one character is flowed out one by one, and then one character "be" is flowed out halfway. That is, the display pattern storage unit in this state is rewritten by shifting the dot pattern by 1 dot to the left.

FIG. 3 (b) shows an example in which the display character "best seller of the week" is flushed to the left end, and the command "← Nagashi" is specified after the display character "best seller of the week". To do. This command character
FIG. 4B shows how the display pattern is expanded by the code group. FIG. 4 (b) shows a state in which "Beth of the week" has been erased halfway. That is, the entire display pattern storage unit in this state is shifted by one dot to the left and rewritten. On the contrary, when the display character "best seller of the week" is flown toward the left end, the display character "best seller of the week" is displayed.
Specify the command "← Nagashi" to output before.

The present invention further has a configuration capable of performing a wide variety of various displays. FIG. 5 is a block diagram of an embodiment of a display control system therefor. Explaining the characteristic part of this embodiment, 15 is a display pattern storage unit having a plurality of display pattern storage regions, and 16 is a combination of output patterns from the display pattern storage regions, and various types of displays are performed on the display unit 7. It is a combination circuit. Since the other points are the same as the basic configuration shown in FIG. 1, description thereof will be omitted. FIG. 6 is a diagram showing an example of designation of commands and characters for designating the display mode of the display control system shown in FIG. 5, and FIG. 7 is a diagram showing an example of development of the display pattern. Hereinafter, the operation of the display control system will be described in detail with reference to FIGS. 5 to 7.

FIG. 6 (a) shows an example in which the display character "This week's bestseller" is erased so that the curtain is drawn toward the left end, and the display character "this week's bestseller" is displayed.
After that, specify the delete command "← MEKURI". FIG. 7A shows how the display pattern is developed by the command character code group. In FIG. 7 (a), it is shown that "S" is erased halfway. That is, the display pattern storage unit in this state is erased from the right side by one vertical dot line at a time. On the other hand, when issuing the display character "Best seller of the week" so that the curtain can be opened toward the right end, specify the command "← mekuri" before the display character "Best seller of the week". To do. In addition, the processing of the display pattern storage unit by the command of "Mekuri" is performed by using the display pattern storage unit 15 having a plurality of display pattern storage regions and an area for storing all patterns of the display character "Best seller of the week". A mask storage area corresponding to the area is provided so that the logical product output is used for display. In other words, taking the state of Fig. 7 (a) as an example, the mask up to the middle of "This week's best sell" and "This week's best seller"
Displayed using the logical product output with the pattern. Then, if the mask is narrowed toward the left end by 1 dot / line, the vertical 1 dot / line is erased from the right side.

FIG. 6 (b) is an example in which the display character "best seller of the week" flows out from the center of the display unit toward the left and right ends and pauses, and then flows to the left and right ends and disappears in the "flash" mode. is there. In this case, the command "← → Nagashi" to be issued is specified before the display character "Best seller of the week", the command "Flash" for the special effect is specified, and "Modoshi" is specified at the end. In addition,
Here, the flash mode is a mode in which the display character is intermittently displayed in reverse. FIG. 7B shows how the display pattern is developed by the command character code group. In the seventh (b), the left display character "Beth of the week" is displayed halfway through "no", and the right display character "to seller" is displayed halfway through "se". There is. That is,
In the display pattern storage unit, the two patterns are rewritten by shifting one dot line from the central portion toward the left and right ends. Further, for flashing, a mask corresponding to two patterns is prepared, and a logical product output and an exclusive OR output of the two patterns and the mask are intermittently switched and displayed. The combinational circuit 16 performs the switching, and is composed of, for example, a gate circuit.

FIG. 6 (c) shows an example in which the "best seller" portion of the display character "this week's best seller" is highlighted. In this case, the command "hanten" is changed to "best
Specify before "Seller", and after "Best seller", specify "Modosi". This command character
FIG. 7C shows how the display pattern is developed by the code group. In FIG. 7 (c), FIG. 7 (b)
A mask corresponding to the character pattern to be displayed in reverse is prepared as in the above example, and is displayed by an exclusive logical product output of the character pattern and the mask through the combination circuit 16. In FIG. 7 (c), the combinational circuit 16
When the character pattern output and the logical product output of the character pattern and mask are switched and displayed, "this week" is displayed in blinking. Further, when only McKu is moved from the right end to the left end, the character displayed in reverse video or blinking changes with the movement. Furthermore, in the case of a partial blinking display command, for example, two display areas are set in the display pattern storage unit 15,
The entire display pattern is stored in one display area, and the entire display pattern in which the blinking display area is blank is stored in the other display area. Then, in the display, these two display areas are alternately read and displayed, so that the display can blink. Further, when performing a horizontal flow display or a vertical flow display as shown in FIG. 4, the entire pattern to be displayed is expanded in one area of the display pattern storage area. It is also possible to store and shift the stored pattern to the other area in dot units, and read and display this. By doing so, it is possible to reduce the processing load as compared with the dot expansion corresponding to the display pattern directly from the character generator by the display data processing unit.

In the display control system of the present invention, the code / data processing routine is prepared corresponding to the command for instructing each display mode as described above. , There is a mode in which the displayed characters flow out from the bottom of the display all at once and disappear, and the opposite mode, a mode in which the display characters flow out vertically from the center of the display and disappear up and down, and the opposite mode. Also in the mode, it is possible to produce a mode in the vertical direction, a mode from the center of the display unit to the left and right ends, and a mode from the center of the display unit in the vertical direction. Furthermore, special effects such as spot and blinking modes, and combinations of each mode can be performed.

〔The invention's effect〕

As is apparent from the above description, according to the present invention, a display pattern is dynamically expanded according to various commands corresponding to a display screen in which display elements are arranged in a matrix, and the display pattern is stored and displayed on the display screen. Since it is displayed, various displays can be made according to requests. In addition, since the processing routine is prepared for each display mode, the system configuration can be simplified, and it is possible to flexibly deal with addition and deletion of display modes and change of specifications. Furthermore, since the display is performed using a display screen in which display elements are arranged in a matrix, display control can be performed in dot units, and various display patterns and display modes that are rich in variations can be adopted.

Thus, the effect brought about by the present invention is remarkable.
