1. An input device comprising:
- an input pad operable to detect a contact with a manipulation body by the use of a variation in capacitance;
a data processor operable to analyze a contact position with the manipulation body on the input pad; and
a switch including an output operable to be switched when the input pad is pressed,wherein the data processor is operable to generate different output signals when the output of the switch is switched and when the input pad detects the contact of the manipulation body without switching the output of the switch.

Abstract
An input device is provided using a capacitive input pad for performing diverse inputs and minimizing an area of a space for arranging a keyboard input unit and an input pad. A multiplex input unit is provided adjacent to input keys constituting a keyboard input unit. The multiplex input unit includes a large-scaled key, a detection switch of which an output is switched when the large-scaled key is pressed, and a capacitive input pad provided on a surface of the large-scaled key. A data processor generates different input signals depending on whether the detection switch is in an OFF state or an ON state when a finger touches the input pad for a manipulation.
