Small-sized information processor capable of scrolling screen in accordance with tilt, and scrolling method therefor
First Claim
1. A small-sized information processor which has, at least, a display device provided with a display screen, and which is used while being held in one hand, comprising:
- command input means for entering a command for scrolling said display screen, in the state in which said small-sized information processor is held in one hand;
tilt detection means for detecting a relative tilt of said small-sized information processor with respect to a reference tilt thereof assumed when the scroll command is entered; and
scroll means for scrolling said display screen on the basis of the relative tilt detected by said tilt detection means.

Abstract
A small-sized information processor which is used while being held in one hand, and which can scroll a display screen in accordance with a tilt. When a scroll start switch is depressed, the tilt angle of a display unit at this time is detected as an initial tilt angle by a tilt sensor. When a predetermined time period has lapsed since the depression of the switch, the tilt angle of the display unit is detected as a second tilt angle by the tilt sensor. The initial tilt angle is subtracted from the second tilt angle by a processing unit, thereby calculating the relative tilt angle of the display unit. The processing unit scrolls the display screen of the display unit on the basis of the calculated relative tilt angle. The scrolling speed of the display unit may well be changed in accordance with the width of the relative tilt angle.
