Abstract

PURPOSE:To move a cursor from a certain position to a target position by single-time key operation by providing a dedicated key and numeric keys for indicating the field number of a movement destination. CONSTITUTION:When a numeric key 1 and the dedicated key 2 are pressed at the same time or successively, a control circuit 5 judges the input of a key for cursor movement and searches a field control table to determines and send an address on a display screen corresponding to the input field number to a cursor control circuit 6. Here, the cursor control circuit 6 moves the cursor (c) displayed on the display screen 7 to the target field position. Consequently, the cursor can be moved to the target position by the single-time operation.

Description

[Detailed Description of the Invention] [Summary] Regarding a cursor control method for a display screen that moves a cursor displayed on the display screen, the cursor can be moved from a certain position to a target position with a single key operation. numeric keys for inputting field numbers, dedicated keys for inputting information to indicate that the input by the numeric keys is input for moving the cursor, and decoding of the input of the dedicated keys. a field management table that stores the address on the display screen corresponding to the field number; and a field management table that searches the field management table in response to the output of the decoding circuit and the numeric keys, and searches the field management table to store the address on the display screen corresponding to the input field number. a control circuit that generates and outputs an address; a cursor control circuit that receives the output of the control circuit and controls movement of the cursor;
and a display screen that receives the output of the cursor control circuit.

[Industrial Field of Application] The present invention relates to a cursor control method for a display screen that moves a cursor displayed on the display screen.

When there are multiple entry fields on the display screen, it is necessary to quickly select the desired field by cursor operation to speed up processing. It is requested that it be moved to.

[Prior Art] FIG. 5 is a diagram showing an example of a display screen. In the figure, 1, 2, 3, etc. in a are the numbers of entry (input) fields, and a plurality of them are provided.

b is the item that follows these numbers. Specifically, the contents of each field number a are displayed. C
is a cursor for field entry. In the figure, it is placed under field number 4. In this way,
The field can be selected by placing cursor C on the desired field number and pressing the entry key on the keyboard.

Here, as methods for moving the cursor C of a to the target field, there are two methods: (1) normal movement one field at a time, and (2) auto-skip method.

In the autoskip method, when data is entered in the last digit of the current field, the cursor C is automatically moved to the next field.

For example, from the position of field "4" to field "9"
This is like moving cursor C to the position.

[Problems to be Solved by the Invention] In the case of the conventional cursor movement method, it is not possible to move the cursor to the desired field with a single key operation. On the other hand, the latter required data to be entered in the last digit of the field. Both had the problem that the cursor could not be moved with a single touch.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a cursor control method for a display screen that allows a cursor to be moved to a target position with a single key operation.

[Means for Solving the Problems] FIG. 1 is a block diagram of the principle of the present invention. In the figure,
1 is a numeric key for inputting a field number, 2 is a dedicated key for inputting information to indicate that the input using the numeric key 1 is for cursor movement, and 3 is a decoding key for decoding the input of the dedicated key 2. 4 is a field management table that stores the address on the display screen corresponding to the field number; 5 is a field management table 4 that searches the field management table 4 in response to the output of the decode circuit 3 and the numeric key 1; A control circuit that generates and outputs the address on the corresponding display screen; 6 a cursor control circuit that receives the output of the control circuit 5 and controls the movement of the cursor; 7 a display screen that receives the output of the cursor control circuit 6; It is.

As the display screen 7, any type of screen can be used. For example, it can be used in CRT, liquid crystal display, plasma display, etc.

[Function] When the numeric key 1 and the dedicated key 2 are pressed at the same time or at different times, the control circuit 5 determines that the input is a cursor movement key, searches the field management table 4, and selects the input field. The address on the display screen corresponding to the number is determined and sent to the cursor control circuit 6. The cursor control circuit 6 controls the cursor C displayed on the display screen 7.
to the target field position. In this way, according to the present invention, the cursor can be moved to the target position with a single operation.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a block diagram showing an embodiment of the present invention. Components that are the same as those in FIG. 1 are designated by the same reference numerals. In the illustrated embodiment, a keyboard 10 and a display device 20 are connected by a cable 30. The keyboard 10 has number keys 1. Keyboard 11 consisting of keys other than numeric keys
and a decoding circuit 3. The dedicated key 2 mentioned above is any one in the keyboard 11 (the shaded part in the figure)
is used. As the numerical keys 1, a normal so-called numeric keypad as shown in the figure is used. The numeric keypad is from 0 to 9
It consists of numeric keys up to, comma keys, etc.

The display device 20 includes a control circuit 5. The main storage device 21 includes a cursor control circuit 61, a display screen 7, and a field management table 4. Field management table 4
The data can be set from the keyboard 10.

The operation of the circuit configured as described above will be explained as follows.

First, a table as shown in FIG. 3 is created in the field management table 4 in advance. This field management table 4 is composed of field numbers and corresponding addresses on the screen.

As for the addresses on the screen, each position on the display screen as shown in FIG. 4 is designated as address 1. Address 2... is determined. This position corresponds to the position of the field number in FIG. 5.

The data in the field management table 4 determined in this way can be changed arbitrarily by the operator using the keyboard 10. In other words, the operator can access any position in the field management table from the keyboard 10 and rewrite the data at the address on the field number 9 screen. For this reason,
As the field management table 4, for example, a RAM is used.

In this state, consider a case where, for example, the cursor is located under field number "4" as shown in FIG. 5, and you want to move the cursor from this position to field number "9". 1 and the dedicated key 2 at the same time or at different times.The control circuit 5 receives the output of the decoding circuit 3 and determines that the field number "9" input from the numeric keys is the next cursor position to be moved to. After that, the control circuit 5 searches for the position of field number "9" in the field management table 4 in the main memory 21, and reads address 9 of the display screen stored at that position. It's crowded.

Thereafter, a signal of the movement position address 9 is given to the cursor control circuit 6. The cursor control circuit 6 changes the position of the cursor C on the display screen 7 from the previous position of "4" to "9".
”. This allows the cursor position to be quickly moved to the target position with a single operation.

[Effects of the Invention] As described above in detail, according to the present invention, the cursor can be moved once from a certain position to the target position by pressing a dedicated key and a numeric key indicating the field number to which the cursor is to be moved. It is possible to provide a cursor control method for a display screen that can be controlled by key operations.
