1. An input device comprising:
- a controller configured to accept input from a coordinate input unit and a key input signal unit and to output a coordinate input signal based on a first input operation, and to output a key input signal based on a second input operation, wherein a low-speed scroll performed on the basis of the coordinate input signal is modified by a key event performed on the basis of the key input signal generated subsequent to the coordinate input signal.

Abstract
An input device is described, which is capable of quickly searching a part of information included in a large amount of continuous data (contents), and a scroll control apparatus using the input device. If a key input operation on one of the operation keys is performed through a key input unit while a low-speed scroll is being performed due to a slide operation performed on the key input unit, the low-speed scroll switches to a jump operation or a high-speed scroll. Thus, it becomes possible to quickly search a part of information included in a large amount of continuous data.

7. A scroll control method using an input device having a controller configured to accept input from a coordinate input unit and a key input signal unit and to output a coordinate input signal based on a first input operation, and to output a key input signal based on a second input operation, the method comprising:
-
determining whether or not the first input operation exists;
performing a low-speed scroll on the basis of the first input operation;
determining whether or not the second input operation exists; and
performing an operation of jumping to a corresponding location if the second input operation exists during the performing of the low-speed scroll.

8. A scroll control method using an input device having a controller configured to accept input from a coordinate input unit and a key input signal unit and to output a coordinate input signal based on a first input operation, and to output a key input signal based on a second input, the method comprising:
-
determining whether or not the first input operation exists;
performing a low-speed scroll on the basis of the first input operation;
determining whether or not the second input operation exists;
determining whether or not an edge motion is being performed; and
performing, an operation of switching from the low-speed scroll to a high-speed scroll if the edge motion is being performed and the second input operation exists during the performing of the low-speed scroll.
