Abstract

The present invention provides a perform both input by relative coordinates and input by absolute coordinates by using the input device of a capacitance detection type. A case body 2 has a display area 3 with a display panel, a first operation area 6 and a second operation area 7. On the inner side of the first operation area 6 and the second operation area 7, a capacitance detection type sensor 10 is provided. The sensor 10 is sectioned into a first area 12 for obtaining a relative coordinate output and a second area 13 for obtaining an absolute coordinate output. A character input operation is made possible by touching the second operation area 7 with a finger 50 and sliding it, and a menu selecting operation or the like is made possible by touching the first operation area 6 with a finger and sliding it.

Description

technical field [0001] The present invention relates to an input device that detects a change in electrostatic capacitance, and an electronic device that uses the input device and is most suitable for portable devices and the like. Background technique [0002] As described in the following Patent Document 1 and the like, there is a device that detects a change in electrostatic capacitance as a pad type input device. In this capacitance detection type input device, a plurality of X electrodes extending in parallel in the Y direction are provided on one surface of a substrate such as a resin film, and a plurality of Y electrodes extending in the X direction are provided on the other surface. Furthermore, a detection electrode as a common electrode is provided between adjacent X electrodes or between adjacent Y electrodes. [0003] The input device sequentially applies a voltage to the X electrode and the Y electrode to obtain a detection output output from the detection elec...
