Portable information terminal, program, and recording medium having the program recorded therein
First Claim
1. A portable information terminal comprising:
- a display for displaying information;
a scrolling device including a disc-shaped member capable of performing a rotating operation centered about an axis and capable of being pressed in the direction perpendicular to a planar surface of said disc-shaped member;
said scrolling device enabling an operator to carry out a first operation and a second operation differing from said first operation;
a first scrolling control device for performing said first operation and said second operation;
wherein said first operation causes said display to scroll through information displayed at a first speed and said second operation causes said display to scroll through information displayed at a second speed slower than said first speed; and
wherein the scrolling device comprises;
a base;
a holder mounted onto the base and including a dial support cylinder projecting perpendicularly from the center of the holder;
a circular scale, including a central hole and slits positioned radially around the central hole, mounted onto the holder and having the dial support cylinder passing through the central hole thereof;
a dial body, including a central hole, having a diameter greater that the circular scale, mounted onto the holder over the circular scale and having the dial support cylinder passing through the central hole thereof;
the disc-shaped member including a central hole, mounted onto the holder over the dial body and having the dial support cylinder passing through the central hole thereof; and
a cylindrical button having a diameter less than that of the dial support cylinder and positioned within the dial support cylinder.

Abstract
High-speed scrolling is performed when an operating dial 35 is rotated taking a central button member 36 as an axis, and low-speed scrolling when pushing either an upper button 42A or a lower button 42C by pushing the operating dial 35 in the direction of an axis of rotation. It is therefore possible to include information it is wished to view, in an appropriate manner within a display range of a screen, with fewer operations by appropriately changing over the speed of scrolling. In addition, as it is possible to operate the operating dial 35 for both high-speed scrolling and low-speed scrolling, when changing over the speed of scrolling, it is possible to change over the speed of scrolling in a straightforward manner without operating members other than the member that has been operated so far.
