Abstract

An input device and its code control method, and it has the data storage function. It includes the coordinate output circuit, a button and roller control circuit, many input button, a storage element and a microcontroller which contains a code compare module and an unlock module. The input button can be numerical button, alpha button or alphanumeric button. The code compare module accepts the input signal from the input button, when the signal is consistent with the code, it can produce an unlock information to the unlock module which can release the lock of the storage element according to the unlock information and restore the validity of the visit operation. When the input signal includes a password setting information, the password compare module will change the password to the input information of the setting password. So based on the password control function, it can decrease the risk of password unlock and prevent others visiting the storage element randomly to protect the data on the input device.
