<p>PROBLEM TO BE SOLVED: To provide an information processing equipment capable of realizing respectively suitable scrolling functions in the vertical and horizontal display modes. SOLUTION: At the time of a vertical display mode, when a rotary switch is operated clockwise, that is upwards along an equipment left side face, contents are scrolled upwards. On the contrary, when the rotary switch is operated counterclockwise, that is downwards along the equipment left side face, the contents are scrolled downwards. On the other hand, at the time of horizontally placing the equipment, the rotary switch is positioned at a lower left corner part. Then, at the time of a horizontal display mode, when the rotary switch is rotated clockwise, that is upwards along the equipment left side face (pertinent to the upper side face at the time of the vertical placement), the contents are scrolled upwards. On the contrary, when the rotary switch is dial- operated counterclockwise, that is downwards along the equipment left side face, the contents are scrolled downwards. The display contents are scrolled as they are by intuitively operating a single rotary switch in either of the vertical/horizontal display modes.</p> |
