Input apparatus having electrostatic sensor |
摘要 |
<p>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 comprises the following: clock signal generating means (2) for generating clock signals; delaying means (6) 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 an electrostatic sensor (5); AND means (3) for receiving the clock signal and the delayed signal as input signals and then outputting these signals as an output signal; and smoothing means (7) for smoothing and outputting the output of the analog switch.
