ABSTRACT:
An input apparatus having a reduced-size electrostatic sensor that can precisely detect an input and then output a signal and, thus, has excellent responsiveness and reliability contains the following: clock signal generating means for generating clock signals; delaying means for generating delayed signals by delaying the signal rise time of the clock signal according to the capacitance detected when a human appendage approaches or contacts the electrostatic sensor; AND means for receiving the clock signal and the delayed signal as input signals and then outputting these signals as an output signal; and smoothing means for smoothing and outputting the output of the analog switch.
