PURPOSE: A device for relaying a multi-pointing device is provided to prevent the pointing device from generating an error by respectively enabling/disabling the pointing devices as adding a control signal for enabling/disabling each pointing device depending on a number of the added pointing devices. CONSTITUTION: A multi-pointing device controlling circuit is equipped with a control typed multi-buffer(20) connecting to a stick pad and a touch pad, a capacitor(C1) connected between a voltage line(VL1) transmitting the supply power to the control typed multi-buffer and a ground power line(GND), and an OR gate(22) connected to the control typed multi-buffer through the first control line(CTL1). The stick pad and the touch pad detect/supply the vector movement set by a user to the control typed multi-buffer by synchronizing with a clock. A pointer driver inputting the vector movement detected from the stick pad and the touch pad through the control typed multi-buffer updates the pointer data with a coordinates value for the position separated according to the movement and a direction set by the vector movement.
