In the present embodiment, the cursor 21 movement pitch is set to 5 pixels, and the screen scroll size set in the STB 10 is half a page. Can be set to. At this time, as shown in FIG.
The TB 10 must judge whether or not the distance of the cursor 21 from the boundary 23 of the window 20 is less than a certain fixed distance, for example, 5 pixels (step S302).
Alternatively, it is also possible to adopt a method of determining whether or not the cursor 21 can move out of the window 20 after the movement. In FIG. 4, since the distance of the cursor 21 from the boundary 23 of the window 20 is larger than 5 pixels, the user can use the cursor direction key 1
When 82 is clicked to control the operation of the cursor 21, the cursor 21 moves 5 pixels according to the instruction (step S303). However, as shown in FIG. 5, when the distance of the cursor 21 from the boundary 23 of the window 20 is smaller than 5 pixels, or when the cursor 21 can move out of the window 20 after the movement, the STB 10 has the remaining contents. Is determined to exceed half a page (step S30
4).

As shown in FIG. 5, the current window 2
The homepage content displayed by 0 is "ABCDEFGH"
And this homepage has been stretched to the right and has the contents of "IJKLMN", which is window 2
Not displayed in 0. Window 2 of cursor 21
The distance from the right boundary 23 of 0 is less than 5 pixels, and the content of the remainder of the home page exceeds half a page, so ST
B10 controls the window scroll bar 22 to display the contents of the homepage as "EFGHIJKL" shown in FIG.
And the cursor 21 is placed in the center of the window 20 in the moving direction of the cursor 21 (step S30).
7) Prevents the situation where the content displayed by the window 20 is continuously scrolled due to the cursor 21 being close to the right boundary 23 of the window 20. Of course, it is also possible to design to move directly to the center position of the window 20.

At this time, if the user wants to continue browsing the contents of the homepage stretched to the right,
By moving the cursor 21 to a position where the distance from the right boundary 23 of the window 20 is smaller than 5 pixels, the surplus homepage contents are only half a page short of "MN" not displayed. The window scroll bar 22 is controlled to scroll the home page display content to the boundary range of the content (step S306), and "GHIJKLMN" shown in FIG. 7 is displayed. Finally, if the cursor 21 is said from the moving direction of the cursor 21, the center of the window 20 (step S30
Place in 7).

Next, FIG. 8 shows another embodiment 2 of the present invention.
It is a display diagram of 0, and the flow of moving the cursor 21 and the first embodiment are almost the same. However, in this example,
STB1 regardless of whether the surplus content exceeds half a page
0 controls the window scroll bar 22 to scroll the contents of the home page half a page to the state shown in the figure, and creates a small block blank area in the right half of the window 20.
