Abstract: The invention provides an input device of the electronic cipher code lock and a corresponding input method thereof, wherein a signal device produces cipher code input information and converts said information into two groups of electrical pulse signals; a measurement and control device measures the electrical pulse signals, decides the order of the electrical pulse signals and calculates correspondingly such that said signals are converted into character sequences including the cipher code elements, and decides whether the current cipher code elements are confirmed to be inputted or not and decides whether the input of all the cipher code elements is completed or not; a confirmation device produces a conformation signal for inputting the cipher code elements; and a display device displays said character sequences and preset prompt information in a rolling and refreshing manner.
