Abstract

PURPOSE:To improve the working efficiency in the titled control system by delivering the tilting angle of a control lever after converting it into the data on the cursor moving speed different from the normal level in case the change of a variation rate is instructed. CONSTITUTION:An instructing means 12 gives an instruction for change of the variation rate of the cursor moving speed. Thus a cursor address control part 11 outputs the tilting angle of a control lever 1 after converting it into the data on the cursor moving speed different from a level changed in a normal state. In such a way, the cursor moving speed is changed. Owing to the instruction of the means 12, it is possible to change the cursor speed in response to the details of a part indicated by a cursor even in case the lever 1 is tilted by an extent equal to a normal level. As a result, both the operability and the working efficiency can be improved in a cursor speed control system.

Description

[Detailed Description of the Invention] [Purpose of the Invention (Industrial Application Field) The present invention provides a method for controlling the movement of a cursor displayed on the screen of a typesetting display device used, for example, by a company or a publishing company. It is related to the technology to

(Prior Art) An external view of the main parts of a typesetting display device is shown in FIG.
100 indicates a CRT display device, whose screen 1
01, for example, a formatted image of a newspaper is displayed. Screen 1
A tablet input unit 102 is provided in front of 01, and characters and the like can be input using an input pen (not shown). On the right side of the tablet input unit 102, a joystick 1, which is an operation stick for moving and displaying a cursor, is installed. The joystick 1 is shown in detail as shown in FIG. 5. The lower part of the joystick 1 extends to the sensor section 104 via the shaft 103, and the joystick 1 is moved in 360° directions as shown by the arrow. In its normal state, it stands vertically as shown in the figure. When the joystick 1 is tilted, the sensor unit 10 detects the direction and angle of the tilt.
Rotation in the X-axis direction and Y-axis direction is grasped by the potentiometers 4 and 5 provided at 4, and information on the tilt of the joystick 1 in the Signal VRX.

Output as VRY. The joystick 1 can be tilted to the maximum tilt position 1A as shown in FIG.
When used with the cursor tilted down in the low-speed movement range shown by 2, the cursor can be moved at low speed and alignment can be finely controlled; on the other hand, when used with the cursor tilted down in the high-speed movement range shown with 3, The cursor can be moved at high speed, and the cursor can be quickly moved to a predetermined position. Here, when the "+" cursor 105 is displayed on the screen 101 as shown in FIG. 7, in order to move this cursor 105 to the center of the article 106, tilt the joystick 1 about 45 degrees to the right of the opposite side. good. At this time, the speed of movement can be controlled by the angle at which the joystick 1 is tilted (see FIG. 6), as described above.

However, in such a conventional cursor display movement control system, when attempting to move the cursor slightly to indicate a minute part, it is necessary to move the joystick 1 within the low-speed movement range 2; If you go beyond this and move to high-speed movement range 3, the cursor will move greatly at high speed. Therefore, it is difficult to perform the work, and especially when the work is for a long time, stress is accumulated. Therefore, it is possible to expand the low-speed movement range 2, but if you expand the low-speed movement range 2, the high-speed movement range 3 will become narrower, and if you need to move quickly, you may have to tilt the joystick 1 considerably. However, in contrast to the above, there is a drawback that operation of the joystick 1 becomes cumbersome when moving quickly.

(Problems to be Solved by the Invention) As described above, in the conventional cursor display movement speed control method, in order to move the cursor minutely, it is necessary to operate within the slow movement range 2, and this range is When it crosses over and enters high-speed movement range 3, the cursor will move at high speed. This resulted in poor work efficiency and increased stress. The present invention was made in view of the drawbacks of the conventional movement speed control method, and its purpose is to change the movement speed of the cursor depending on the fineness of the part indicated by the cursor. Therefore, it is an object of the present invention to provide a cursor display movement speed control method that can improve operability and work efficiency.

[Configuration of the Invention (Means for Solving Problems)] In the present invention, the cursor displayed on the screen is moved by obtaining the moving direction based on the inclination direction of the operating culm and obtaining the moving speed based on the inclination angle. In the movement speed control method of the cursor display, there is an instruction means for instructing a change in the rate of change of the movement speed, and when the instruction means instructs to change the rate of change, the inclination angle of the operating culm is always maintained. The moving speed of the cursor is changed by comprising a speed data conversion output means for converting the converted moving speed data into data of a different moving speed and outputting the converted data.

(Function) According to the above configuration, when the operating stick is tilted by the same amount as usual by giving an instruction using the instruction means, the data of the movement speed that is normally output and the data of the responsible movement speed are output. The cursor is moved based on this data, and the speed of the cursor movement can be changed.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of the main parts of a typesetting display device employing the method of the present invention. A switch 12, which is an instruction means for instructing a change in the rate of change of the cursor movement speed layer, is provided on the upper side surface of the joystick 1 in the figure. The switch 12 is a normally open switch and is closed only while being pressed. The non-movable contact of the switch 12 is grounded, while the movable contact is connected to a voltage V via a pull-up resistor. 0 is given. The voltage of the movable contact of the switch 12 is directly applied to the AND gate 15A, and
These signals are applied to AND gates 15B via inverters 16, respectively. Further, the AND gate 15A is given a clock sent from an original oscillator (not shown) via the signal line 9, and the clock on the signal line 9 is divided by the frequency divider 13 and the clock on the signal line 15B is fed to the AND gate 15B. given through. ANDGATE 15A.

The output of 15B is given to addition/subtraction sections 10A and 10B via an OR gate 17. Therefore, when the switch 12 is not pressed, the original clock sent from the original oscillator is output from the OR gate 17 via the AND gate 15A, and when the switch 12 is pressed, the signal line is output from the OR gate 17. 14, the frequency-divided clock is output via the AND gate 15B. On the other hand, when the joystick 1 is tilted, as explained in FIG.
It is output as analog signals VRX and VRY. These analog signals VRX and VRY are supplied to AD converters 6.7 and 6.7, respectively.
are sent to the
It is output to the subtraction units 10A and 10[3. Reference value data is supplied to the addition/subtraction units 10A and 103 via the signal line 8, and the addition/subtraction units 10A.

10B creates a difference between this reference value data and the outputs of the AD converters 6 and 7, masks the clock output from the signal line 9 or the frequency divider 13 according to this difference, and controls the cursor address. It outputs to section 11. in particular,
Figure 8 (VRX in the range shown by T1 between the broken lines of A>)
The falling edge of X changes, and the lower limit reference value 1 and the upper limit reference value 1
is given, and if the falling edge of VRX is in the range of T2, it is a stationary object and the cursor will not move. Now, if the joystick is tilted and the fall of VRX falls ΔX earlier than the lower limit reference value 1, as shown in Figure 8 (B), the pulse of the original clock will be masked by this -ΔX. ,
This Mars number P1 is taken out as a subtractive force at predetermined intervals.
is output. Therefore, the cursor moves in the X direction by subtracting the number of pulses P1 at every predetermined time interval. On the other hand, the joystick is tilted, and as shown in FIG. 8(C), the fall of VRX is the upper limit criterion +i! +△ from 2
If it falls later than X, the pulse of the original clock is
The number of pulses P2 is masked by X and taken out as an addition, and the number P2 of pulses is output at predetermined intervals. For this reason, the cursor is moved in the X direction by the number of pulses P2 at each predetermined time interval.
is added and moved. Therefore, if the original taro clock has a frequency of, for example, 1/2, the number of pulses for the above addition/subtraction will be 1/2 of the above example, and the moving speed of the cursor will be 1/2.

In another example, when the joystick 1 is vertically installed, the A/D converter 6,
7 outputs a signal (100, 100>), and if the maximum slope is given to each, and there is a change of "50", the reference value data will be 11oo J. Then,
With joystick 1 standing vertically,
The difference between the outputs of the converters 6 and 7 and the reference value data is rOJ, and at this time, the original clock (signal line 9) is
00J pulse shall be sent. Then, when the maximum tilt is given to the right only in the X-axis direction, the AD converter 6
Since the output is r150 J and the difference is "50", the clock is masked in accordance with this difference, and the original clock of the r150 J pulse is output from the addition/subtraction unit 10A. Furthermore, when the maximum tilt is given to the left only in the /The subtraction unit 10A outputs an original clock of "50" pulses. A similar relationship also holds true for the AD conversion section 7 and the addition/subtraction section 10B. When the clock having the number of pulses created in this way is output from the addition/subtraction unit 10A and IOB to the cursor address control unit 11, the cursor address control unit 11 correspondingly outputs the address of the cursor display position. The data is counted up or down and the data corresponding to the cursor in the frame memory corresponding to the screen is rewritten.

In a typesetting display device having such a configuration, if the switch 12 is not pressed, the clock difference between the vertical position and the maximum tilted position of the joystick 1 is "50", and the cursor movement speed is , shall change like a straight line 301 in FIG. On the other hand, when the switch 12 is pressed, the clock is divided and the frequency is set to 172. When the joystick 1 is in the vertical position and in the maximum tilted position,
The clock difference becomes "25", and the moving speed of the cursor changes as shown by a straight line 302 in FIG. That is, if the boundary between the low-speed movement range and the high-speed movement range is drawn by the broken line 303 in FIG. It is possible to move the cursor at speed.

[Effects of the Invention] As explained above, according to the present invention, the moving speed of the cursor can be changed to a speed different from the usual speed by giving an instruction using the indicating means. The cursor can be moved at a low speed, and therefore the operability of moving the cursor display and the efficiency of work based on cursor movement can be improved.
