<p>In the case where a game controller is provided with plural elements for obtaining outputs by changes in resistance values, currents also flow through some of the elements not detected, increasing current consumption. Also, the number of input lines to a CPU increases, putting a heavy load on the CPU. Plural variable resistors each comprising a resistance member and an elastically deformable element are connected to common fixed resistors, and midpoints between the variable resistors and the fixed resistors are connected to an A/D converting circuit as common output paths. Connection parts connected to the variable resistors are switched in order to a ground potential, whereby voltage outputs based on changes in resistance values of the variable resistors can be obtained in order from the common output paths. <IMAGE></p> |
