Furthermore, a keyboard 16 is connected to the control unit 11, through which various search information and control information are input, and a printing device through which searched image information, input image information, and various information are printed! 17 are connected.

FIG. 1 shows the keyboard 17. As shown in FIG. In addition to well-known alphabet keys, the keyboard 17 also has a cursor displayed on the CR7 display device 15.
Cursor movement keys 17a to 17d to move in the required direction
, a confirmation key 17e for confirming the position of the cursor, and a speed designation key 17f for switching the moving speed of the cursor. These keys 17a to 17f are non-lock type switches that are turned on only when they are pressed.

In the above configuration, cursor movement control will be explained.

FIG. 2 shows an example of the display screen of the CR1 display device 15. This CR1 display device 15 includes icons 15a for setting various functions, and image information 15 such as characters and symbols.
b and a cursor 20 are displayed, and by pointing the icon 15a with the cursor 20, various functions can be set.

In such a display state, first, the CR1 display device 1
A case will be described in which the cursor 20 displayed on the screen of No. 5 is moved largely from point A to point eight.

Here, when the confirmation key 17e is operated, the cursor 20 blinks, and when the operating force on the key 17e is released, the cursor 20 is turned on. In this state, in order to move the cursor 20 quickly, turn off the speed designation key 17f and operate the operation keys 17a and 17b, and the movement information 30 shown in FIG. 3 is generated on the keyboard 16 every 1/100 seconds. This movement information is supplied to the control unit 11. This movement information 30 is, for example, 8-bit movement m information 3 indicating the amount of movement of the cursor 20 in the X and y directions.
It is composed of, for example, 2-bit key state information 30k indicating the states of QX, 30V, the confirmation key 17e, and the speed designation key 17f. The movement amount information 3QX
, 30V, for example, a clock signal is counted every 1/100 seconds while the operation keys 178 to 17d are operated, and this count value is set respectively, and the movement amount information 30x, 30y is includes code bits corresponding to the operations of the operation keys 178 to 17d. The key state information 30 also includes keys 178 .
The state response UT of 17f is set as follows.

Key 178 on, key 17f off..."0" key 17
e off, key 17f on...t+ 1 +i primary key 7
8 on, key 17f on...Pa 2 "Key 17e off, key 17f off...Pa 3" In this case, key status information 30k
is set to "3".

When the movement information 30 generated in this manner is supplied to the control unit 11, the control unit 11 uses the cursor speed information 40 shown in FIG. ! The moving speed of the cursor 20 on the screen 15 is determined. That is, the controller 11 performs the following calculation.

X-Al　XX+X.

Y=A2 xy+Y mouth Here, A1 and A2 are the speed coefficients in the X direction and the X direction when the key 17f, which is preset in the cursor speed information 40, is in the off state, and this speed coefficient A1. A2 is set in the relationship A1>Bt A2 >82 with the speed coefficients B1 and B2 when the speed designation key 17f is turned on. Further, X1y is the movement amount information 30X in the x1y direction set in the movement information 30,
3oy, Xo 1Ya is the position of the cursor 20 before movement (in this case, the digit M of point A).

By performing this Korean movement every time the movement information 30 is supplied, the cursor 20 is moved from point A to point B at high speed. Then, when the cursor 20 reaches point B and the operating force on the operating keys 17a and 17b is released, the cursor 20
0 is stopped at point B.

Next, a case will be described in which the cursor 2o is accurately moved from point B to point 0. In this case, speed designation key 17f
When the operation keys 17b and 17d are operated with the on state, for example, movement information 30 is generated on the keyboard 16 as described above, and this movement information l1i30 is
It is supplied to the lI section 11.

The control unit 11 performs the following calculation based on the supplied movement information 30 and the cursor speed information 40 shown in FIG. 4 to determine the amount of movement of the cursor 20.

X=131　XX+Xl+ Y-B2 XV+Y.

Here, B1 and B2 are speed coefficients in the X direction and X direction when the key 17f, which is preset in the cursor speed information 40, is in the on state, and
x, X direction movement amount information set to 30X, 30V
SXa and Ya are the position ra of the cursor 20 before movement (in this case, the position of point B). This mis is the movement information 3
By doing this every time 0 is supplied, cursor 2o is set to B
It is accurately moved from the point to the 0 point at a low speed. Then, when the cursor 2o reaches point B and the operating force on the operation keys 17b117d and speed designation key 17f is released, the cursor 20 is stopped at point B.

According to the above embodiment, different speed coefficients A1, A2 and B1, B2 set in the cursor speed information 40 are selected in response to the operation of the speed designation key 17f, and based on the selected speed coefficients, The amount of movement of the cursor 20 is changed.

Therefore, the moving speed of the cursor 2o can be changed as required in accordance with the operation of the speed designation key 17f, so the cursor 20 can be moved quickly and accurately.

Furthermore, since the cursor 20 can be moved at high speed, it is possible to move the cursor 20 at high speed in a high-resolution CR7 display device.
Even when moving a large distance, it takes less time than in the past.

In the above embodiment, the speed designation key 17f is configured as a non-lock type switch, but operability can be improved by configuring it as an on-lock type switch that is maintained in the on state, for example.

Further, for example, a cursor speed change key may be provided on the keyboard 16, and while the speed change key is operated, the speed coefficient set in the cursor speed information 40 can be arbitrarily changed by operating the numeric keypad of the keyboard 16. This is even more convenient because the cursor movement speed can be changed arbitrarily.

It goes without saying that various other modifications can be made without departing from the gist of the invention.

[Effects of the Invention] As detailed above, according to the present invention, the cursor t→
By changing the movement of the cursor as required, it is possible to speed up the movement of the cursor and provide a display control device that can accurately move the cursor number 0.
