Description

[Detailed Description of the Invention] The present invention provides a display display device, particularly a display display device such as a Japanese input device, which includes a character tab setting key for instructing character tab setting, and a decimal key for setting a decimal tab.
At least a tab setting key and a tab skip key for moving the cursor to either the character tab position or the decimal tab position are provided to improve the operability of key operations, In addition, one or more decimal point positions for displaying numbers can be set in advance under the decimal tab setting mode at any desired X coordinate position on the display screen, and the cursor movement can be temporarily controlled when entering numbers. lock so that numbers are displayed above the decimal point position, release the lock in response to input of characters or decimal points, and thereafter display characters or numbers at the position corresponding to the position of the cursor. The present invention relates to a display device that controls the display so as to display numbers with the decimal point aligned.

In a Japanese input device, by inputting kana characters and pressing a kanji conversion key, the kana characters are converted to kanji characters and Japanese characters are input. Even with such Japanese input devices, when inputting tables,
It is desirable to freely input multi-digit numbers by aligning the decimal points within the frame in the table. Conventionally, when inputting numbers with the decimal points aligned, the method used was to display the numbers in a separate work area on the display screen and then transcribe them into the desired frame. was. Furthermore, even in systems that adopt a method in which the decimal point position is set in advance, the decimal point position is checked, and the cursor is placed at the digit position of the number to be input and input. For this reason, when trying to adopt a system in which numbers are directly input and displayed at the desired position, there are problems in that the operability is poor and key operations are complicated. Furthermore, in the past, some devices have been made to perform an action corresponding to a character tab and an action corresponding to a decimal tab, but in the past, it was not possible to distinguish between the character tab and the decimal tab. If you want to use the tab setting key to set the "tab" without first using the tab setting key, and then perform the character tab operation, use the "skip key for character tab to perform the action corresponding to the character tab". To operate the decimal tab, or to perform a decimal tab operation, a ``decimal tab skip key for performing an operation corresponding to the decimal tab'' was operated. For this reason, when inputting characters, etc., it is necessary to judge whether to perform a character tab operation or a decimal tab operation before performing key operations.
The problem was that it was difficult to operate.

The purpose of the present invention is to solve the above-mentioned problems and to enable input by shifting the decimal point position by simply pressing the number keys as the numbers are read out. Therefore, the display device of the present invention includes a keyboard, a decoder that decodes the type of key press on the keyboard, and a decoder that decodes the type of key press on the keyboard, and a a cursor control unit that updates the cursor position on the display screen; a display; and a display memory control unit that has a display memory in which information corresponding to the display screen of the display is stored; , Based on the press of a key including a letter key or number key on the keyboard, a display corresponding to the corresponding letter or number is displayed on the display screen, and the cursor is moved to the next display position instruction. In a display device, a tab skip button is provided on the keyboard to instruct the cursor to be moved to either the default character tab position or the default decimal tab position. key, a character tab setting key that is placed on the keyboard and instructs to set a character tab, and a decimal tab that is placed on the keyboard and gives the position of the decimal point of a numerical value. It has a decimal tab setting key that specifies the character tab information specified by the character tab setting key and an address corresponding to a predetermined position on the coordinate axis on the above display screen, and the decimal tab setting that is specified by the character tab setting key. a format buffer in which the decimal tab information specified by the key is set; and the character tab information or the decimal key set on the format buffer in response to the pressing of the tab skip key. - A tab that detects the position where tab information exists, controls the cursor control unit to move the cursor to the position, and locks the cursor movement by the cursor control unit when the presence of the decimal tab information is detected. and a control unit, which detects the presence of the decimal tab information and causes the display memory control unit to display numbers on the decimal tab in response to pressing of the numeric key while the cursor movement is locked. Keys that are displayed in the direction of higher digits than the location of the information, and that lock the cursor movement is released in response to pressing a character key or decimal point key on the keyboard, including subsequent character keys or number keys. The character key is controlled so that the corresponding display is performed according to the display position of the cursor based on the pressing of Alternatively, based on the depression of a key including a decimal point key or a numeric key, control is performed so that a display corresponding to the key is displayed and the cursor is displayed at the next position. This will be explained below with reference to the drawings.

FIG. 1 is an explanatory diagram illustrating an embodiment of numerical input according to the present invention, and FIG. 2 shows a main part configuration of an embodiment of the present invention.

Numerical input in the present invention will be explained first. In the present invention, as a mode for inputting numbers, a decimal tab is set to preset the position of the decimal point, and numbers can be input based on the position of the decimal point. FIG. 1 shows this aspect. In this case, preset decimal tab 1 corresponding to, for example, the X coordinate on the display screen,
Numerical input is performed by determining the position of the decimal tab 1 as the decimal point position. FIG. 1 shows a mode in which a new number ``67, 8'' is input in a state where the digits ``12, 3'' and ``4, 5'' have been input. That is, the above decimal
With tab 1 set at a predetermined X coordinate position, the tab skip key is pressed as will be described later with reference to FIG. Then, cursor 2 is set at the position where decimal tab 1 is present. The cursor 2 is then temporarily locked in that position while the next numeric key is pressed, as will be described below with reference to FIG. In other words, even if the number "6" is inputted and then the number "7" is inputted as shown in the figure, the cursor 2 remains locked and the inputted number is placed above the position of the decimal tab 1. For example, "6" and "67" are displayed at the digit positions.
This state is maintained as long as the number key is pressed continuously, and when a character key other than a number or comma or a decimal point key is pressed, the lock state is released.
Return to normal display mode. That is, cursor 2
A decimal point, numbers, and characters are displayed corresponding to the position of the cursor 2, and the cursor 2 is shifted, for example, one character to the right in preparation for the next display. FIG. 1 shows a state in which the digit ``67'' is input, followed by a decimal point ``.'', and then the digit ``8'' is input.

Numerical input is performed as described above, but in the case where operations corresponding to character tabs and operations corresponding to numeric tabs are mixed, the present invention operates as follows. That is, before inputting Japanese text, etc., a character tab setting key and a decimal tab setting key are set in advance at the position where the action corresponding to the character tab is performed and the position where the action corresponding to the decimal tab is performed, respectively. Use this to configure different tab settings. When actually inputting Japanese text, etc., the user operates a "single" tab/skip key to move the cursor to one of the above tab setting positions. That is, when the cursor is moved, an operation mode corresponding to one of the tabs is automatically generated depending on which tab is set at that position. Because of this, when actually inputting Japanese sentences, the operator must use the "Tab/Skip key".
By simply operating , you can enter a mode that performs the action corresponding to either tab.

FIG. 2 shows the main structure of an embodiment of the present invention in which the above-mentioned display mode is implemented. In the figure, numeral 3 is a keyboard, 4 is a decoder that decodes the type of key pressed on the keyboard, 5
6 is a line format buffer that has an address position corresponding to the X coordinate position of the display screen, and the character tab (marked with an x in the figure) and the above-mentioned decimal tab (marked with a : mark in the figure) are set; 6 is a cursor control 7 is a cursor X coordinate position register, 8 is a cursor Y coordinate position register, and 9 is a tab control unit that controls the display position of the cursor 2 shown in FIG. 10 detects the presence of character tabs and decimal tabs and presets the cursor to the corresponding position.
Cursor 2 while on the flop and in the set state
11 is a display memory control unit which has a built-in screen memory and controls so that information corresponding to the display screen is set on the screen memory; 12 is a character generator; 13 represents the display.

The keyboard 3 includes, for example, () character tab setting key, () decimal tab setting key, () cursor movement key, () tab skip key,
() character key, () period (decimal point) key,
() number keys, () comma keys, etc. have been created.

First, let's talk about the tab setting mode. In this case, the operator presses the cursor movement key to move the cursor 2 to a desired position on the X coordinate. That is, in response to the depression of the cursor movement key, the cursor control unit 6 increments the contents of the cursor X coordinate position register 7 by 1 in order to move the cursor 2 one digit at a time in the X-axis direction, for example. Of course, at this time, the contents of the cursor Y coordinate position register 8 also correspond to the Y of the cursor.
It is set corresponding to the coordinate position. When setting the decimal tab (marked in the figure) to the illustrated coordinate position X ₀ , the contents of register ₇ are set to the coordinate value
With the cursor displayed at the corresponding position on the display 13, the decimal tab setting key on the keyboard 3 is pressed. As a result, the decimal tab information is inserted into the corresponding address position of the buffer 5 indicated by the contents of the register 7. Of course, when setting the character tab (indicated by an x mark in the drawing) at the coordinate position _X1 in the drawing, the character tab setting key is pressed while the contents of the register 7 are at the coordinate value _X1 . These character tabs and decimal tabs are
It is possible to set multiple locations on the coordinates.

When entering numbers in the mode shown in FIG. 1 with the decimal tab set at the position _X0 in the figure as described above, the procedure is as follows.

(1) Assume that the cursor 2 is now at the position of the X coordinate value X ₂ , and that the tab/skip key on the keyboard 3 is pressed in this state.

(2) In response, the tab control section 9 reads the contents _X2 of the register 7 and the contents of the address position corresponding to the coordinate position _X2 in the row format buffer 5.

(3) In this case, since decimal tab information does not exist at the address position corresponding to the coordinate position _X2 , the tab control section 9 gives a plus one instruction to the cursor control section 6. As a result, the contents of register 7 become the value (X ₂ +1).

(4) The tab control unit 9 reads the contents of the register 7 and the contents of the line format buffer 5 in the same manner as in operation 2 above. However, since there is no decimal tab information at this position, the tab control section 9 is moved to the cursor control section 6 in the same way as in operation 3 above.
Instruct plus 1 for.

(5) Similar operations are performed thereafter, and when the contents of the register 7 reach the value _X0 , the tab control unit 9 detects the presence of decimal tab information.

(6) With this, the tab control section 9
Set flop 10.

(7) When flip-flop 10 is set,
The cursor control section 6 and display memory control section 11 are notified of the lock state. That is, from now on,
Cursor 2 becomes locked at the position of coordinate _X0 . The cursor 2 then stops at the position where the decimal tab 1 exists, as shown in the top row of FIG.

(8) Next, the operator presses the number key "6", for example.
When the button is pressed, the display memory control section 11 causes the number "6" to be displayed on the display 13 as shown in the second row of FIG.

(9) Next, when the number "7" is pressed, a display as shown in the third row of FIG. 1 is displayed. During this time,
Cursor 2 remains locked.

(10) Next, when the operator presses the decimal point key, the flip-flop 10 is reset, and the cursor control section 6 and display memory control section 11 are notified of this.

(11) Therefore, the decimal point is displayed at the position corresponding to the position of the cursor 2 as shown in the fourth row in FIG. 1, and the contents of the register 7 are incremented by one digit.

(12) Next, when the operator presses the number "8", the number "8" is displayed corresponding to the position of cursor 2, as shown in the bottom row of Figure 1, and cursor 2 is shifted one digit to the right. be done.

When displaying numbers, the display is performed as described above, but in response to the character tab, a mode is entered in which the following operations are performed. In other words, the character tab (illustrated ×
mark), when inputting characters,
In response to depression of the same tab skip key used to control the decimal tab, the cursor 2 is set at the position where character tab information exists. Thereafter, each time a character is input, the character is displayed corresponding to the position of the cursor 2, and the position of the cursor 2 is shifted to the right.

As explained above, according to the present invention, decimal
Corresponding to the position of the tab information, the information is input and displayed with the decimal points aligned in response to the number keys being pressed. Therefore, the operator uses the tab/skip key to change the position of cursor 2 to decimal.
After adjusting to the location of the tab information, you can simply press the number keys according to the reading of the numbers without worrying about the location of the decimal point. In addition, when actually inputting text, etc., the operator does not have to judge whether to perform the action corresponding to the character tab or the decimal tab, and only a single tab can be used. - You can enter either mode simply by operating the Skip key.
