Abstract
An electronic lock includes an input apparatus. The input apparatus includes a keypad module and a processor module. The keypad module includes plural button devices arranged in plural rows and in plural columns. The processor module includes a signal-processing unit configured to, when operating in a work mode, repeatedly perform an emission process of inputting a detection signal to each column of button devices, and repeatedly perform a scan process to detect, for each row of button devices, the detection signal outputted from any row of button devices. The detection signal includes a pulse wave composed of plural pulses. The signal-processing unit is further configured to generate and output an input signal corresponding to one of the button devices when detecting the detection signal.
