摘要：<p><P>PROBLEM TO BE SOLVED: To provide a "touch panel device" capable of reducing power consumption for applying a reference voltage to an A/D converter. <P>SOLUTION: A reference voltage control means 26 is formed so as to control the voltage value of the reference voltage when the duration of a non-operation state measured by a timing means 27 in the non-operation state reaches the threshold time to be a value lower than the voltage value of the reference voltage when a touch panel 2 is being operated and when the duration of the non-operation state measured by the timing means 27 in the non-operation state does not reach the threshold time. <P>COPYRIGHT: (C)2010,JPO&INPIT</p>
