Abstract

PURPOSE:To improve the operability of a cursor shift controller by combining a cursor shift key and a shift key to set the cursor shift speed in many steps and therefore attaining the cursor shift at a proper speed according to applications. CONSTITUTION:When both a cursor shift key and a shift key are pushed continuously via a keyboard unit 1, both key and shift codes are produced and supplied to a cursor shift speed control mechanism 2. The cursor shift speeds are set previously in response to the shift states of an alphabet shift key, a digit shift key, etc. and determined by the shift states. These cursor shift speed (cursor shift interval time) are sent to a cursor control/display control circuit 4 by the interruption given from a timer circuit 3. The circuit 4 receives the parameter of the cursor position, etc. and displays the cursor at an optional position on a CRT display 5.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cursor movement control device that sets the cursor movement speed in multiple stages and causes the cursor to move at an appropriate speed.

[Technical background of the invention and its problems]

In data entry devices, cursor movement keys such as character, address, key character, and pack space keys that indicate input field positions are usually equipped independently from shift keys such as alphabetic shift keys and numeric shift keys. It is. If you keep pressing the cursor movement key, regardless of the switching or shift status,
The cursor is always moved at a constant speed.

By the way, as the storage density of floppy disks and the like increases year by year, the number of characters displayed on one screen is also increasing. Along with this, the conventional cursor movement speed is slow and slow when moving dozens of characters.
This had the disadvantage of reducing work efficiency. However, simply increasing this speed may cause the contradictory drawback that it is too fast for several cursor movements. For this reason, there is a desire to set multiple types of cursor movement speeds and use them appropriately.

[Purpose of the invention]

The present invention has been developed based on the above-mentioned needs, and the cursor movement speed can be set in multiple stages by combining the cursor movement key and the shift key, and the cursor can be moved at an appropriate speed according to the application. An object of the present invention is to provide a cursor movement control device with improved operability.

[Summary of the invention]

The present invention focuses on a shift key that exists independently of the cursor movement key, and uses this shift key to change the cursor movement speed into multiple stages.

For this reason, the cursor movement speed is defined in advance by the combination K of the cursor movement key and the shift key, and there is a cursor movement speed control mechanism that determines this, and a cursor control that follows the cursor movement speed determined by this cursor movement speed control mechanism. The display control circuit is equipped with a timer circuit that generates and outputs a clock for passing the variable make to the display control circuit, and the display control circuit obtains the above parameter necessary for cursor display by the interrupt issued from the timer circuit, and according to the above definition. The cursor movement is instructed at an arbitrary time interval according to the specified time interval.In this way, operability is improved by selectively using the multi-level cursor movement speed.

[Embodiments of the invention]

Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, reference numeral 1 denotes a keyboard for inputting data, which includes normal data keys, function keys, shift keys, and cursor movement keys. 2 is a cursor movement speed control mechanism that determines the cursor movement speed when the cursor movement key is pressed.
Explain using diagrams. 3 is a timer circuit. The timer circuit 3 follows the cursor movement speed determined by the cursor movement speed control mechanism 2 and generates a clock for passing cursor control parameters to the cursor control 4 display control circuit 4. 4 is a curve control and display control circuit for displaying a cursor and desired data. 4 circuits, display screen memory, character generator and display control LS
It is a ready-made unit consisting of I. 5 is a CRT display on which a cursor and desired data are displayed.

The present invention will be briefly explained using FIG.

When both a cursor movement key and a shift key are held down via the keyboard unit 1, a key code corresponding to the cursor movement key and a shift code indicating a shift state corresponding to the shift key are generated, and these codes are transmitted to the cursor movement speed control mechanism 2. supplied to Here, a cursor movement speed is assigned in advance to each shift state of the alphabetical shift key, numeric shift key, etc., and the cursor movement speed of the cursor movement key is determined depending on the shift state. The cursor movement speed is the time required to move the cursor by one character.

The cursor movement speed (cursor movement interval time) obtained here is passed to the cursor control 4 display control circuit 4 as a parameter necessary for cursor display by an interrupt issued from the timer circuit 3. The internal configurations of the timer circuit 3 and the cursor control circuit 4 are well known, and detailed explanations thereof will be omitted here. Cursor Control 4 When the display control circuit 4 receives parameters such as the cursor position, it controls the display of the cursor at an arbitrary position on the CRT display 5. In this way, by combining an arbitrary shift key and a cursor movement key, the cursor movement speed can be divided into several steps for the number of shift keys, and by pressing a cursor movement key together with an arbitrary shift key, the cursor movement speed can be set at an appropriate speed. It becomes possible to move the cursor.

Hereinafter, the operation of the embodiment of the present invention will be explained in detail using FIG. 2 and subsequent figures. FIG. 3 is an operational conceptual diagram conceptually showing the operation of the embodiment of the present invention.

In the diagram, alphabetic shift, numeric shift, and kana shift.

This example shows a case where all four types of shift keys for kana character shift are used and the cursor movement speed is divided into four stages. Therefore, 200++ m5ec for alpha shift, 150 ;nrnsec for numeric shift, or td for cold shift.
100 +n5ec, character shift from 50?・=
A cursor movement speed (cursor movement interval time) is assigned in advance, such as maec.

Here, when the character advance key and number shift are kept pressed, the key code of the character advance key and the number shift code are transmitted to the cursor movement speed control mechanism 2.

The cursor movement speed control mechanism 2 uses this shift code to adjust the cursor movement speed to 150.-
It is determined to be msec.

By the timer circuit 3, parameters such as the position for displaying 1507 planes 5ele per force are passed to the cursor control 4 display control circuit 4, and this circuit 4
The cursor advance is repeated every ec, and the cursor is displayed on the CRT display 5.

If you want to repeat the busy cursor at-bans five times as shown in Figure 2 as an example of the cursor display, press the cursor-at-bans key and the number shift key F) 1
It will take 50 m5ec x 5 = 750mBeQ. Similarly, in alphabetical shift, 1000100O,
Kana shift is 500 m5ec.

Kana character shift is 250 m5ec, which is K. In this way, when the cursor movement is repeated dozens of times, the cursor movement can be performed at arbitrary time intervals by keying in using an arbitrary shift key.

〔Effect of the invention〕

As described above, the present invention provides the following effects.

(1) There is little influence on the hardware, and the present invention can be realized by simply adding a force and crane movement speed control mechanism to the conventional hardware configuration.

(2) Operability is improved by selectively using the cursor movement speed of the multi-stage NK.
