ABSTRACT:
A cursor control device includes a main body, a circuit board, a base, a touch support stand, a touch sensor and a knock sensor. The circuit board is disposed within the main body. The base is disposed within the main body and above the circuit board, and includes an elongated slot. The touch support stand is mounted on the base and aligned with the elongated slot. The touch sensor is supported on the touch support stand and electrically connected to the circuit board. In response to a touching action on the touch sensor, a screen scrolling signal is generated. The knock sensor is mounted on the circuit board and under the touch support stand. The knock sensor is triggered when the touch support stand is moved to touch the knock sensor.
