The electric filed E is located between the touch panel 10 and the performance button 161. When the performance button 161 is not depressed, the conductive member 70 is not located in the electric field E. When the performance button is depressed by the player's finger F by a distance S, the member is located in the electric field E. Consequently, the performance button 161 is depressed, the capacitance varies accordingly owing to the movement of the conductive member 70. Measuring the variation in the capacitance permits the depression of the performance button 161 to be detected.  <P>COPYRIGHT: (C)2011,JPO&INPIT
