A multiple external input device for a mobile game phone and its system are provided to widen the range of utilization of a mobile terminal and contribute to activation of a game or other software industry based on the mobile terminal. Manipulation buttons including a direction key(103) and action keys(104,105), generate a button signal. A ROM(102) stores button configuration information obtained by matching the manipulation buttons and keypad buttons. A central processing unit(101) converts the button signal into a keypad button signal. The first I/F module(106) transmits the keypad button signal to a mobile terminal. The second I/F module(107) bypasses the externally inputted keypad button signal to the mobile terminal.
