Abstract
In a touch panel device, an output control unit controls a process of outputting touch information acquired by a sensing unit and a touch detection unit of a touch sensor panel to host equipment, where the information indicates presence or absence and a coordinate of a touch of an indicator to the touch sensor panel. A state sensing unit senses an operation state of the sensing unit or the touch detection unit. A state restoration unit restores the sensing unit or the touch detection unit in the abnormal state to a normal state, based on a detection result of the state sensing unit. Upon detecting an abnormal state in the state sensing unit, an output control unit stops an output of the touch information to the host equipment for a fixed period of time.
