  • Publication number: 20190346959
    Abstract: Electrodes Ex and regions of top plate opposed to electrodes Ex constitute switches SWx that have capacitances varying when the regions of top plate are depressed from top plate toward electrodes Ex. Depression detection circuit calculates the capacitance change amounts of switches SWx indicating changes of the capacitances from a reference value. Depression detection circuit calculates the maximum value and sum of the capacitance change amounts of switches SWx. When the capacitance change amount of at least one switch SWx exceeds threshold TH_EDGE and a situation in which the ratio of the maximum value to the sum is equal to or greater than threshold COMP_LEVELx has lasted for the number of repetitions in SW_DET_COUNT, depression detection circuit determines that the switch having the maximum value of the capacitance change amount is in a depressed state.
