Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an input display device, and more particularly to continuous input of character codes on an input display device.

Some known input display devices include a keyboard for input and a CRT display device. In this input display device, when an operator presses an input key on a keyboard, input data is transferred to the current cursor position and input characters are displayed. After displaying, the cursor is moved from the current cursor position to the next possible input position, for example, to the right, and character input/display operations are performed. Input data is entered by moving the cursor to the desired position on the CRT screen. For this reason, known input display devices have circuits for moving the cursor one character at a time in each direction up, down, left, and right, and a continuous operation circuit for efficiently moving the cursor. .

Furthermore, when inputting characters, a continuous operation circuit is used to perform character input operations continuously to improve efficiency.

According to such conventional technology, when inputting characters,
Continuous movement in the right direction is possible, but when inputting the same data into a specific digit position on each line, or when modifying or creating figures, kanji fonts, etc. using the display device, the character The input direction is only to the right, so you need to move the cursor frequently.

For example, when inputting the character data "A" in one digit of each line of the display device, the operator's key operation is to press the character key for "A", the character "A" will be displayed at the cursor position, and the cursor will be , move to the next input position (second digit). To input the character data "A" continuously in the same column of the next line, move the cursor to the next line, and then move the cursor one character to the left to return the cursor to the same column of the previous line. let

By repeating this operation thereafter, data input of "A" in the first digit is completed over all digits.

As mentioned above, cursor movement, character key presses, and operator key operations are frequently required.
In order to input efficiently and accurately, it is necessary to have a function that allows continuous input of characters in each direction, up, down, and to the left.

As a means to solve the above-mentioned problem, a key that performs continuous operation for character input keys is added, and it can be easily solved by operator operation, but there are two types of similar keys, one for characters and one for cursor. This not only complicates operations for the operator but also requires additional keys, which is not a good idea. Rather, it is desirable to have a function that uses existing keys and operates with simple operations.

Therefore, an object of the present invention is to easily input up, down, and
An object of the present invention is to provide an input display device that allows characters, etc. to be input continuously in both the left and right directions.

In the present invention, if the operator presses a character key while the cursor is continuously moving, the character key processing that does not move the cursor is performed every time the cursor is moved. It also allows continuous input using character keys.

FIG. 1 shows a specific example of the present invention. The keyboard operated by the operator is provided with a continuous key for continuous commands, four cursor keys for commanding the direction of cursor movement, and character keys for commanding character input. While the operator's consecutive keys are held down,
A continuous operation control circuit 1 is provided which performs continuous operation of cursor keys and character keys by outputting continuous operation signals at a rate of 10 to 12 times/second. The cursor operation control circuit 2 performs processing to move the cursor in response to a cursor movement signal from the character key operation circuit section when the operator presses a cursor movement key and operates a character key, outputs a cursor address to the cursor register 4, and displays the cursor. Output a signal. The character key control circuit 3 performs character key processing (that is, outputs a display character code and a cursor movement signal) when a character key is pressed by an operator. The cursor address register 4 stores the cursor address being displayed, and this content indicates the character display address. When a character key is operated, the character code is transferred to the storage unit of the display control unit 5 at the address indicated by this content, and then transferred. Back cursor operation control circuit 2
updated with the output signal of The display control section 5 has a storage section that stores data regarding patterns and cursors to be displayed on the display section 6, and further outputs display data to the display section 6 at all times. Data output from the display control section 5 is displayed on the display section 6.
If the cursor key and character key are pressed when the output signal (continuous operation signal) from the continuous operation control circuit 1 indicates continuous operation, the operation of the character key (continuous operation) is performed, and the signal indicates continuous operation. Even if the character key is not pressed,
No character key action is performed, and unless a continuous action is indicated, a character key action of inputting one character is performed each time a character key is pressed.

These states are determined by the character key operation determining section 7. Character key output control section 8 prohibits output of a cursor movement signal and does not move the cursor by character key operation when character key control circuit 3 operates during continuous operation based on the output of character key operation determination section 7. Only the display character data is output and transferred to the storage section of the display control section 5, and when the character key control circuit 3 operates while not representing continuous operation, the cursor movement signal and the display character data are displayed using the cursor address register 4. It operates to transfer the data to the memory of the control unit 5 and output it. When the operator presses the cursor key to move the cursor by one character in either the up, down, left or right direction, the cursor operation control circuit 2 operates and updates data by one character in the direction indicated by the cursor to the cursor address register 4. Output. The cursor display signal is output to the storage section of the display control section 5 indicated by the cursor address register 4, and the result is displayed on the display section 6, completing the cursor movement operation for one character.

To perform continuous operation here, press the continuous key while pressing the cursor key and press the continuous operation circuit 1.
If you operate the continuous operation control circuit 1 10 to 12 times/
By outputting continuous operating signals at the rate of seconds,
The above-mentioned operation is repeated, and continuous operation is possible. When only a character key is pressed, the character key control circuit 3 operates via the character key operation determination unit 7.
The display data for display is provided by the character key output control unit 8.
is transferred to the storage section of the display control circuit 5 indicated by the cursor address register 4, and the result is transferred to the display section 6.
is displayed. Since the continuous operation signal does not indicate continuous operation, the cursor movement signal is not prohibited by the character key output control unit 8, and the cursor operation circuit is
is sent to move the cursor to the next input position, for example to the right of the displayed character.

When a continuous key, a cursor key, and a character key are pressed, the cursor operation control circuit 2 and character key control circuit 3 are operated as follows by the output signal of the continuous operation control circuit 1.

The character key operation determination unit 7 sends a status signal indicating character key processing during continuous cursor operation to the character key output control unit 8.

The character key control circuit 3 sends display data and a cursor movement signal to be displayed by a predetermined operation.
It is sent to the character key output operation control section 8. The character key output control unit 8 prohibits the output of a cursor movement signal since character key processing is in continuous operation, prevents cursor movement using the character keys, and outputs only the display data to be displayed using the cursor address register 4. By transferring the data to the storage section 5, characters are displayed on the display section 6.

Of course, the cursor movement operation is performed in parallel with the character key operation.

As described above, by pressing a character key while pressing a continuous key and a cursor key, continuous operation of the character key in any one of the up, down, left, and right directions is possible.

According to the present invention, continuous operation of up, down, left, and right character keys is possible without adding dedicated keys, by continuously pressing keys, cursor keys, and character keys, and it is possible to perform continuous operations in the up, down, left, and right directions of character keys, and it is possible to do so at a low cost and with editing functions. Improvement can be measured.

Further, for the operator, the continuous operation of the cursor and character keys can be performed using only one key for continuous operation instruction, which simplifies input operations.
That is, when continuous input is desired, the user presses the continuous key, uses the cursor keys to specify one of four directions, and uses the character keys to input the desired character. Note that when a continuous key is pressed and a character is pressed, continuous input is performed only in the right direction, as in the prior art, so there is no deterioration in operability.
