Abstract

PROBLEM TO BE SOLVED: To change a scroll speed by changing move interval time that is a parameter of a scrolling speed with an input signal. SOLUTION: Scroll is started by inputting an input signal, and a scrolling speed is updated. A timer 5 updates a parameter 'elapsed time' that supervises elapsed time after scrolling which is stored in a storage device 4. A deciding means 33 compares the parameter 'move interval time' with 'elapsed time' which are stored in the device 4 and outputs a redisplay signal to a displaying means 32 when the 'elapsed time' exceeds the 'move interval time'. The means 32 interrupts a scroll start signal through an inputting means 31 and a redisplay signal through the means 33 and clears the 'elapsed time'. Also, it fetches a current 'display coordinate' from a storing means 4, calculates a 'display coordinate' after scrolling and stores it in the means 4. Further, it fetches a display object 'file' from the means 4 and shows it on an output device 2.

BEST MODE FOR CARRYING OUT THE INVENTION

(Embodiment 1) An embodiment of the screen scroll control device will be described in detail below. FIG. 1 shows the configuration of the screen scroll control device. In the figure, 1 is an input device, 2 is an output device, 3 is a processing device, 31 is input means, 32 is display means, 33 is determination means, 4 is a storage device, and 5 is a timer.

In the present invention, an input device 1 and an output device 2 are connected to a processing device 3 as shown in FIG.

[0008] The storage device 4 stores a parameter "movement interval time".
"Elapsed time", "display coordinates", and a display object "file" are stored.

The input device 1 is a start switch for starting a screen scroll process, and is a speed change switch for changing a scroll speed. The scroll is started by the input of the input signal, and the scroll speed is changed. The signal input from the input device 1 is taken into the input means 31.

The input means 31 receives an input signal from the input device 1 and outputs a scroll start signal to the display means 32. In addition, the scroll speed parameter “movement interval time” stored in the storage device 4 according to the type of the input signal.
To change.

The timer 5 has a parameter “elapsed time” for monitoring the elapsed time after scrolling stored in the storage device 4.
To update.

The determination means 33 stores the parameter “movement interval time” and the parameter “elapsed time” stored in the storage device 4.
When the “elapsed time” exceeds the “movement interval time”, a re-display signal is output to the display means 32.

The display means 32 takes in the scroll start signal from the input means 31 or the redisplay signal from the determination means 33 and clears the parameter "elapsed time". Also,
The current “display coordinates” are fetched from the storage device 4, the “display coordinates” after scrolling are calculated, and stored in the storage device 4. Further, the display object “file” is fetched from the storage device 4 and displayed on the output device 2.

FIG. 2 shows a flowchart for scrolling the screen display position. In step 51, an input signal input from the input device is input to the input means 31. Step 52
Captures the scroll start signal output from the input means 31 into the display means 32, and the display means 32 displays the display object “file” on the output device 2. A step 53 clears the parameter “elapsed time” stored in the storage device 4. Step 54 takes in the parameter "display coordinates" stored in the storage device 4, step 55 calculates "display coordinates" after scrolling, and step 56 stores "display coordinates" in the storage device 4. In step 57, the “movement interval time” stored in the storage device 4 is taken into the determination means 33, and it is determined whether or not the “movement interval time” is “0”. If the value is "0", scrolling is terminated. If the value is not "0", the flow proceeds to step 58. A step 58 compares the “movement interval time” stored in the storage device 4 with the “elapsed time”. When the “interval time” is equal to or exceeds the “elapsed time”, the process returns to step 57. When the “elapsed time” exceeds the “interval time”, the process proceeds to step 59. In step 59, the redisplay signal output from the judging means 33 is taken into the display means 32, and the display means 32 displays the display object "file" on the output device 2.

FIG. 3 shows a flowchart for changing the parameter "movement interval time" of the scroll speed by the input means 31. In step 62, when the input signal is input or the "moving interval time" is not "0", step 63 is executed, and otherwise, the process ends. In step 63, if the input signal is the "speed-up signal", step 66 is performed; otherwise, step 64 is performed. In step 66, the value of “movement interval time” is reduced, and step 62 is performed. Step 6
4 executes step 67 when the input signal is the deceleration signal, and otherwise executes step 65. In the step 67, the value of the "moving interval time" is increased, and the step 62 is executed. In step 65, if the input signal is the "stop signal", step 68 is performed; otherwise, the process ends. A step 68 stores “0” in the “movement interval time”.

FIG. 4 shows a screen configuration of the output device. Area 7
Reference numeral 1 denotes a display window of a display object “file” displayed on the output device 2 by the display unit 32. The area 72 is a button on the screen that scrolls the display area upward. The area 73 is a button on the screen for stopping scrolling. The area 74 is a button on the screen that scrolls the display area downward. Reference numeral 75 denotes a mouse cursor for associating the amount of movement of the mouse with the coordinates on the screen indicated by the mouse. By placing a cursor 75 on the area 72 and inputting a signal from a mouse, the input means 3
1, an input signal "speed-up signal" can be input, and the screen scroll control device starts scrolling upward.
By overlaying a cursor 75 on the area 74 and inputting a signal from a mouse, the input signal "speed-up signal" can be input to the input means 31, and the screen scroll control device starts scrolling downward. If the scroll before input is in the forward direction with the input signal, the input signal acts as a "speed-up signal", and in the reverse direction, the input signal acts as a "deceleration signal". By overlaying the cursor 75 on the area 73 and inputting a signal from a mouse, an input signal "stop signal" can be input to the input means 31, and the screen scroll control device stops scrolling.

According to the above-described function, after the scroll for moving the display area continuously at a constant speed by one input operation is started, the scroll speed can be changed by one input operation.

(Embodiment 2) The difference between the input device 1 of the first embodiment and the first embodiment will be described below. FIG. 1 shows the configuration of the screen scroll control device. In the figure, 1 is an input device, 2 is an output device, 3 is a processing device, 31 is input means, 32 is display means, 33 is determination means, 4 is a storage device,
5 indicates a timer.

In the present invention, an input device 1 and an output device 2 are connected to a processing device 3 as shown in FIG.

The input device 1 is a start switch for starting a screen scroll process, and is a speed change switch for changing a scroll speed. The scroll is started by the input of the input signal, and the scroll speed is changed. The signal input from the input device 1 is taken into the input means 31.

FIG. 5 shows a keyboard type input device. The key 82 is a key for indicating the direction of scrolling. By pressing this key, an input signal “speed-up signal” can be input from the input device. The arrow of the key 82 corresponds to the direction of scrolling. If the scroll before input is in the forward direction with the input signal, the input signal acts as a “speed-up signal”. Acts as a "signal." By pressing the middle circle, the input means 3
1, an input signal "stop signal" can be input.

According to the above-described functions, the scroll speed for continuously moving the display area at a constant speed by one input operation can be started, and then the scroll speed can be changed by one input operation.

[0023]

According to the present invention, it is possible to change the scroll speed by one input operation after starting the scroll for continuously moving the display area at a constant speed by one input operation.
