1. An input device that detects variation of electrostatic capacitance between a plurality of electrodes extending in the X and Y directions of a substrate caused by an input mechanism comprising:
- a substrate divided into at least a first region and a second region;
a data processing unit that, in the first region, when it is sensed that an operated portion at which electrostatic capacitance has varied moves, generates a relative coordinate output signal based on a detection signal with respect to the movement of the operated portion and in the second region, when the operated portion is detected or it is sensed that the operated portion moves, generates an absolute coordinate output signal based on a detection signal with respect to the operated portion.

Abstract
An input device having a substrate having a first region and a second region. The first region is configured to receive movement operations by an input mechanism, such as to control a pointer or cursor on a display. The second region has an input pad, such as a number pad, to generate absolute signals in response to contact by the input mechanism.
