The present invention relates to a simple keyboard for display instructions for indicating areas, graphic areas, etc.

(Conventional technology) Conventionally, one sentence displayed on a display screen consisted of nine lines.

For example, a keyboard (hereinafter abbreviated as KB) is used as a device for specifying phrases, areas, etc., and specifying graphic areas.
There were full character array tablets (hereinafter abbreviated as TB), digitizers, mice, trackballs, joysticks, handwriting input devices, voice input devices, lightbens, etc.

In addition, methods for giving instructions using these devices include (1)
Methods using a cursor displayed on the display screen, character-by-character blinking, and reverse display (hereinafter referred to as display media), (2)
) A method of directly instructing characters without using a display medium on a display screen, and (3) a method of directly instructing a character on a display screen. To give specific examples, method (1) includes KB and TB's ``method using cursor keys such as φJ and rJIJ, method using a mouse, joystick, or trackball, method using a light ben to move the cursor, and method using a digitizer. There was a method to move the cursor using .Method (2) is a method in which the device searches for the desired character by using KB for kana-kanji conversion or ROMA character kana-kanji conversion, and a method in which the device searches for the desired character by inputting a character using TB. There are two methods: a method in which the device searches for the character by inputting it using a handwritten input device, and a method in which the device searches for the character by inputting the character by voice input.

Further, as method (3), there is a method in which a displayed character or figure on the display screen is pressed down using a light ben or a touch panel, the device searches for the position, and displays the character or figure.

Next, the software for executing each of the instruction methods described above and its operation will be explained with reference to the block diagrams shown in FIGS. 2 to 5.

FIG. 2 is a block diagram of a display device using a KB, a mouse, a joystick, and a trackball as input devices for the instruction.

In the figure, 2-1 is an input device such as a KB, a mouse, a joystick, or a trackball, and 2-2 is a central control device (hereinafter referred to as
This is an input control device (hereinafter referred to as KB controller and abbreviated as KBC) that sends a signal to the CPU (abbreviated as CPU) 2-3. 2-3

This is a display (hereinafter abbreviated as DISP) that displays characters and graphics using C synchronization control signals.

In the apparatus shown in FIG. 2, it is assumed that the cursor (or high-intensity display, etc.) is currently located at the first character in the first row of the display screen of DISP 2-10, and the rest are displayed normally. Next, for example, a cursor movement signal from the input device 2-1 is sent to K B
When entering C2-2, K B C2-2 is CPU
Issue an interrupt command to 2-3. The CPU that received this
2-3 is K to know the contents of the interrupt of KBC2-2.
B Read the contents of C2-2. At this time, commands for moving the cursor up, down, left and right are written in the KBC 2-2. After reading this, the CPU 2-3 changes the attribute data of the MEM 2-5 in order to change the cursor display position. Further, when the CPU 2-3 receives an execution command after a cursor operation command, the attribute is set to cursor+high brightness. In this way, you can change the cursor position and specify characters.

FIG. 3 is a configuration block diagram of a device that uses a KB (when converted into kana-kanji, etc.) TB, a voice input device 1 and a handwriting input device as input devices for the instruction.

In the figure, 3-2 to 3-10 are respectively 2-2 in Figure 2.
Since it is the same as ~2-1O, the explanation is omitted here. In this case, the characters specified on input device 3-1 are

B Sent to C3-2. When the KBC 3-2 finishes storing the data, it issues an interrupt command to the CPU 3-3.

CPU 3-3 receives this and reads the contents of KB C3-2. Next, CPU 3-3 uses MEM3-
5 is read and compared with the read data of KBC3-2. If the same address is found (or there may be more than one address), the attribute of that address is rewritten to be inverted (or blinked). This is how you specify characters.

FIG. 4 is a block diagram of the configuration of a device that issues the instructions using a touch panel.

In the figure, 4-1 is a touch panel.

The touch panel 4-1 divides the display vertically and horizontally and detects the position pressed by the operator, and there are optical types, conductive rubber types, and the like. 4-2 is touch panel 4-
This is a touch panel controller that controls 1. 4-3

4-. It is set in a fixed position so that it can correspond to 10 display addresses. The signal pressed on the DISP 4-10 is detected by the touch panel 4-1 as X-axis and Y-axis signals. Upon receiving this signal, the touch panel controller 4-2 converts the value into an address on the DISP 4-10, and sends an interrupt signal to the CPU 4-3. Next, CP
U 4-3 reads the data from touch panel controller 4-2 and rewrites the attribute of MEM 4-5 at that address so that it is inverted (or blinked). This is how you specify the character position.

FIG. 5 is a block diagram of the configuration of a device that issues the instructions using a light pen.

In the same figure, 5-1 is a light pen, and 5-2 is a CPU 5-3 and DC5- which receives the light signal from the light pen 5-1.
It is a light ben controller that sends a signal to 4.

5-3 to 5-10 are the same as 2-3 to 2-10 in FIG. 2, respectively, so their explanation will be omitted here. In the device shown in Figure 5,
When the light pen 5-1 presses down on the DISP 5-10, if there is light in the pressed area, the light pen 5-1 sends a signal to the light pen controller 5-2 at the time the light is received. The light pen controller 5-2 receives the push signal and the optical signal from the light pen 5-1, and controls the CPU 5-3 and the DC 5-.
Issue an interrupt command to 4. DC5-4 has a counter that holds the output address and raster at that time when it receives this signal. Next, the CPU 5-3 reads the address counter of the DC 5-4. And the address M
Rewrite the attribute part of EMS-5 so that it is reversed (or blinked). This is how the character position is specified.

By the way, the above display means (display device and input device)
Both are used in computers, word processors, etc., but recently, the usage of computers, word processors, etc. has become more versatile, and applications for special purposes are being considered. Some examples include a method in which a single word processor is used by students and teachers, and the teacher uses another KB to indicate errors and grade answers to questions on the screen that the students enter from a KB; Examples include a method in which a single computer is used by an operator and a doctor, and the operator enters and corrects medical data on a display screen according to the doctor's instructions.

(Problem to be Solved by the Invention) However, when one display device is shared by multiple people as in the above usage example, the conventional input device
Since B and the like are all highly versatile, they are not suitable for specific uses such as those used by teachers and doctors only for instructions on the screen for the following reasons.

That is, the KB, TB, handwriting input device, and human voice input device are expensive and have many useless functions.

Light pens and touch panels cause operator fatigue, small characters often cause incorrect instructions, and cannot be remotely controlled, making them unsuitable for sharing display screens. TB, handwriting input device, joystick.

Trackballs are large devices and take up a lot of space. mouse,
Trackballs and joysticks require skill in making fine adjustments, such as when displaying characters in a shifted manner. light pen,
KB (in the case of kana-kanji conversion method, etc.), TB, and voice input devices cannot indicate parts (spaces, etc.) that are not displayed on the display screen. Furthermore, touch panels have other problems, such as the display screen getting dirty, and light pens that cannot be used on anything other than a CRT.

The present invention solves the above-mentioned problems when a conventional input device is used only as a means of indicating characters, figures, etc. on a screen, and is inexpensive, small, easy to handle, and highly efficient in use. The purpose of this invention is to provide a simple keyboard for display instructions on the display screen.

(Means for Solving the Problem) The present invention includes a cursor key and a small number of function keys, and by pressing one or more of these keys in combination, characters, words, and sentences displayed on a display screen can be displayed. This is a simple keyboard for display instructions on a display screen, which is capable of specifying areas for graphics and text.

(Function) The simple keyboard of the present invention realizes instructions for arbitrary characters, words, and sentences displayed on the display screen, as well as instructions for arbitrary areas of figures and sentences, using cursor keys and a small number of function keys. In order to realize this arbitrary instruction using as few keys as possible, the instruction is given by a combination of pressing one or more keys.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention, in which (a) is an external view and (b) is an enlarged view of a key. In this example,
The nine types of keys shown in FIG. 1(b) are used as the cursor keys 10, and the "start/
Three types of keys are used: ``clear'', ``add'', and ``correct'' keys.

Here, the "Start/Clear" key is used to start the instruction procedure when text is displayed on the display and no instructions, and to clear the instruction character when the instruction character is already displayed. Use when you want to.

The "add" key is used to display a different instruction character when the instruction character has already been displayed.

The "correction" key is used to invalidate the execution of the last key in the instruction procedure and restore the original state by one step.

By repeating this, it is possible to return to the initial state.

Next, the functions of the cursor keys 10 will be explained.

Instructions using the cursor keys 10 include, for example, (1) pressing the "start/clear" key, (2) setting the initial state shown in FIG. , reduction, and designation of the text shown in FIG. 9 are performed in this order.

FIG. 7 shows instructions that can be displayed in the initial state in association with pressed keys and indicated positions on the display. The instructions include those listed in the table.

In Fig. 7, ■ etc. in the keys to be pressed means that when one key is pressed, an instruction will be displayed at the corresponding position on the display, and when there are multiple keys, they will be displayed at the corresponding position on the display. This means that when pressed at the same time, an instruction appears at the corresponding number position on the display (the view of the figures is the same in Figs. 8 and 9).

Figure 8 moves the initial instructions given in Figure 7.

It is a figure which shows the press key and the press result when enlarging and reducing. This movement, etc. is performed using nine types of cursor keys.

In the same figure, Fig. 8(a) shows the case where one of the eight types of cursor keys except the "○" key is pressed, and in this case, the instruction on the display is displayed in the same shape as the pressed key. Move in the direction indicated. Figure 8(b) shows the seventh
As a result of moving the indicated area in Figure (g)■ to the lower left, the part beyond the outer frame disappears, and then the
It is a figure which shows the result of moving by the method of figure (a).

Figure 8 (C) shows the case where the rOJ key and any of the other eight keys are pressed simultaneously; in this case, Figure 7 (
g) The indicated area (■) expands in the direction indicated by the pressed key. FIG. 8(e) shows the method of FIG. 8(a).
This shows the case where the instruction in Figure (a) ■ is moved diagonally upward to the right and then enlarged. FIG. 8(d) shows a method of reducing the designated area.
In this case, a total of three keys, the arrow key in the direction of reduction and the arrow keys on both sides thereof, are pressed at the same time. FIG. 8(d) shows the case where the designated area shown in FIG. 7(g) (2) is reduced by this reduction method.

FIG. 9 is a diagram showing pressed keys and pressing results when a sentence is specified based on the initial instruction given in FIG. 7 or the instruction after movement shown in FIG. 8.

In this case, first indicate the starting point or ending point with the cursor.

Next, by pressing the "○" key, high brightness display is made. Next, if that point is the starting point, the "φ" key presses the "8" key. In the case of the "φ" key, the two characters, that character and the next character, will blink (or be highlighted), and "
8" key, all characters on that line after that character will blink (or be displayed in reverse). FIG. 9(a) shows the case where the "8" key is pressed. As shown in Figure 9(b),
If you further press the r84 key, the display will expand line by line to the following lines. At this time, if the end point is after the last display line, pressing the r8J key increases the display area one character at a time from the left end of the line next to the last display line, as shown in FIG. 9(c). On the other hand, if the end point is in the final display line, pressing the "middle" key will reduce the display area one character at a time from the right of the final display line, as shown in FIG. 9(d). In this way, the end point can be determined. Also, if it is the starting point or the ending point, it will be "middle" as shown in Fig. 9 (8) for Fig. 9 (a).
The starting point can be found by starting the same operation as above using the key or rffJ key.

Next, the configuration of the display means using the simple keyboard of the present invention will be explained with reference to the block diagram of FIG. 6. In addition, in the same figure, each component 1-2 to 1-10 is the same as 2-2 to 2-1O in FIG. 2, so a description thereof will be omitted here. l-1 is the simple keyboard.

Further, in FIG. 6, a key press signal from the simple keyboard 1-1 is transmitted from the KBC 1-2 to the CPU I-3. If it is emitted by simultaneous pressing, K B Cl-2 will be as shown below (in the margin below).

Total 552 (species) 55
Two types of signals are sent to CPUs 1-3. On the other hand, 12
To read seed key on/off 2” = 4096
Seed signals are sufficient. Therefore, K B Cl-2 is
It is sufficient to send at most 16 bits of data to the CPU 13.

Furthermore, as a display screen of DISPI-1o, for example, one having the configuration shown in FIG. 10 can be mentioned. This display screen is a monitor with 1280 dots horizontally and 960 dots vertically, and each character and figure has a unit of 20 dots horizontally and 24 vertically, and has a character portion and a space portion. Next, the screen configuration is the number of columns (1 to 63) in the first row.
However, the number of rows (1 to 39) is displayed in the first column. Therefore, the maximum displayable characters on one screen is 63 x 39 = 2
It has 457 characters. When the address of the display character is displayed in hexadecimal code, the address of each location on the screen can be expressed as a numerical table, for example, and if this is expressed on the X and Y axes, the location on the screen (x, y ) is binary hexadecimal X (000001) ~ (111111) (
01)H~(3F), 4Y (000001)~
(100111) (01) H to (27) □, which can be associated with the hexadecimal code.

Next, operations for specifying characters, words, and sentences on the screen of the display means using the simple keyboard of the present invention, as well as specifying areas for figures and sentences will be explained with reference to FIG.

It is now assumed that sentences and the like are displayed on the display screen of DISPl-1o (see FIG. 10) in FIG. 6 using a KB (not shown), and that they are displayed normally.

Next, by pressing the "start/clear" key of the simple K B 1-1, an instruction operation start signal is sent to the K B C12. Upon receiving this, K B Cl-2 issues an interrupt command to the CPU 13 . Next, when the button is pressed in one of the modes shown in FIG. 7, the cursor display signal changes to K B
It is input to C1-2 and held. On the other hand, CPU
13 is K to know the contents of interrupt of K B C2-2
B Read the contents of C2-2. At this time, K B
A code for displaying a cursor at a position corresponding to the pressed key in FIG. 7 is written in C1-2. The CPU 1-3 that reads this reads the corresponding attribute data stored in the MEMl-5, for example, if the ■ keys in FIG. 7(C) are pressed simultaneously, the CPU 1-3 reads the address (041) ~
(07F) Data to output the cursor to H
17. In this way, initial display is performed, for example, on the first line of the character display area of the display screen. Next, move the initial display.

Enlargement, reduction (see Figure 8) and text designation (see Figure 9) are performed. For example, as in the case of FIG. 8(a), when the cursor key with an arrow is pressed, K B
The CPU 13 reads the code written in C1-2 and changes the cursor display position, so MEM1-5
The attribute data of is changed as shown in FIG. In addition, in FIG. 11, the starting point character address Ao, X, Y coordinates (x
,,yo) and the coordinates and address after movement are shown. Furthermore, CP the execution command after the cursor movement command.
If U 1-3 is received, use the "○" key to display the cursor + high brightness. In addition, CPU l-3 is K
The code read from B C1-2 is held until one instruction command is completed, that is, until the "start/clear" key is pressed to enable correction. In this way, any position on the display screen can be specified.

(Effects of the Invention) As described in detail above, according to the present invention, anyone can instruct texts and figures displayed on the display at any time with simple operations, and the simple keyboard of the present invention Because it is small and lightweight, it is ideal as a display instruction device for display devices, and can be expected to improve operability and save space.
