Patent ID: 7999792

Claim:
An electronic apparatus comprising: a coordinate input device which inputs coordinate data, the coordinate input device including a coordinate input surface that is disposed on a front side of a keyboard provided on a top surface of a casing and has a size including at least part of a position of a hand when the hand is placed at a home position on the keyboard; a range detection module which detects a range of contact of the hand with the coordinate input surface of the coordinate input device; a setting module which sets a disabling range on the basis of the range detected by the range detection module, the disabling range being a range where the coordinate data input by the coordinate input device is disabled; an elapsed time determination module which determines whether a preset time elapses from a time when the disabling range is set by the disabling range setting module; a setting canceling module which cancels the setting of the disabling range in a case where the elapsed time determination module determines that the preset time has elapsed; a determination module which determines whether the coordinate data, which is input by the coordinate input device, is included in the disabling range which is set by the disabling range setting module; and a process module which executes a process for disabling the coordinate data when the determination module determines that the coordinate data is included in the disabling range.
