Electronic device and coordinate detecting method
First Claim
1. An electronic device comprising:
- a housing;
a display that is disposed inside the housing and that displays predetermined information;
an electrostatic-capacitance touch panel that allows visible light, corresponding to display contents of the display, to pass through the electrostatic-capacitance touch panel;
a transparent member that protects the electrostatic-capacitance touch panel and that allows the visible light corresponding to the display contents of the display to pass through the transparent member; and
a depression detector that detects deformation of the transparent member, whereinwhen a plurality of two-dimensional coordinates are determined in order by the electrostatic-capacitance touch panel and, when a predetermined amount of deformation is detected by the depression detector, after determining the two-dimensional coordinates,then at least one of two-dimensional coordinates, detected during a predetermined time period prior to a time when the deformation is detected, is validated; and
a two-dimensional coordinate, detected before the predetermined time period prior to the time when the deformation is detected, is not validated,wherein the predetermined time period does not include a deformation of an amount equal to or greater than the predetermined amount of deformation.

Abstract
An electronic device includes a housing, a display that displays predetermined information, an electrostatic-capacitance touch panel that allows visible light corresponding to display contents of the display to pass through the touch panel, a transparent member that protects the touch panel and that allows the visible light to pass through the transparent member, and a detector that detects deformation of the transparent member. The touch panel detects a pair of two-dimensional coordinates indicated by an indicator, wherein when the touch panel detects a plurality of pairs of two-dimensional coordinates and when the detector detects a predetermined deformation amount; at least one pair of two-dimensional coordinates detected during a predetermined time period prior to a time when the deformation is detected is validated.
