[Prior Art] • The general notebook computer is based on portability and space saving. It integrates the various types of pointing devices into the notebook computer to replace the hard-to-carry table Φ-type mouse. Various forms of pointing devices such as a keyboard emulation function, a touchpad pointing device (TouchPad), a trackball (TrackBall), a trajectory bar (TYackPoint), and the like. As shown in the keyboard analog mouse device of the ninth figure, the conventional technology switches the function of simulating the mouse button on the keyboard 3 by using the function switching key 3 1 0 in simulating the movement of the cursor, and each function key includes analog sliding. Left mouse button 3 1 1, function is like the left mouse button function; simulate mouse right button 3 1 2, function is like sliding right button function, control cursor left shift button 3 1 3 ', control cursor left shift; control The cursor up key 3 1 4 controls the cursor up; the control cursor® moves down 3 1 5, the control cursor moves down; and the control cursor right shift key 3 1 6 controls the cursor to the right. However, the above functions can only be used to control the movement of the cursor in the upper, lower, left and right directions. For example, in the US patent US6, 1 (8), the function of the button in the 875, the function of the mouse is difficult to accurately manipulate the cursor on the control cursor. The mobile master is the target. As indicated by the touch panel pointing device of the tenth figure, it is the pointing device most commonly used in notebook computers today, and the cursor movement is controlled by the touch track pointing device 41, but it needs to be used multiple times back and forth. Touching the trackpad pointing device 41 to control the cursor can actually move the cursor to the target position, and 1309374 makes the manipulation difficult. In the touch panel pointing device of US Pat. No. 6,606,244, the touch panel pointing device is inconvenient to assemble, and is caused by its components such as a central processing unit (CPU) and a memory (MEMO RY).

As shown in the block diagram of the keyboard controller of the present invention, the keyboard controller 14 includes a matrix scanner 1 4 1 , a button signal generator 1 4 2, a processing unit 1 4 3, a host bus interface 14 4 and an internal The busbar 1 φ 4 5 ; wherein the matrix scanner 1 4 1 and the button signal generator 1 4 2 are the address acquisition unit 1 4 0 'home address accommodation unit 1 4 0 to obtain a matrix address, The processing unit 1 4 3 determines that the signal is transmitted to the main bus interface 14 4 4, and the internal bus 1 4 5 is located in the address acquisition unit 1 4 0, the processing unit 1 4 3 and the host confluence The interface 1 4 4 is used for transmitting signals. Each node on the matrix circuit 13 provided by the present invention corresponds to each button of the plurality of buttons 2 1 on the keyboard device 2, whereby each button corresponds to each matrix address on the matrix circuit 13; then the keyboard control The device 1 4 11 1309374 scans the matrix circuit 13 by using the matrix scanner 1 4 1 through the scanning bus bar 16 , and cooperates with the button signal generator 1 4 2 to obtain the matrix address of an action button; wherein the matrix address is processed through The unit judges 1 4 3 and processes the button signal operated on the keyboard device 2 2, and then sends the processed signal to the host bus interface 1 4 4 via the internal bus bar 1 4 5, and then passes the host bus bar 1 7 To host 1 5. The pointing function switching key 2 1 0 1 on the keyboard device 2 of the present invention is used to switch the operation modes of the twelve pointing function keys, and when the processing unit 1 4 3 obtains the matrix address of the action button as the pointing function Switching the matrix address of the key 1 1 0 1 makes the twelve pointing function buttons switch between the function mode and the function mode of using the pointing function, and the meat is one and the same. There are two kinds of the same function fs ^ The twelve pointing function buttons can be used to point to the function of the device, if the pointing function mode is not used, the general keyboard function; wherein the twelve pointing functions are pressed When you are pointing to the function of the device: The function key for simulating the left mouse button 2 1 0 2 is the function of simulating the left mouse button, and the function button for simulating the right mouse button 2 1. (J 3 is loose and slippery The function of the right button, the electric button on the Tengbei surface 2 1 0 4 is the function selected on the computer surface 5 electric chest shell face box · key 2 1 0 b is the function of the computer page I© Asked to build 2 1 0 6 is the control tour • The direction is up, the second direction key 2 1 0 7 is the control The cursor is directed to the upper right* direction, the third direction key 2 1 0 8 is for controlling the cursor to the right direction, the fourth direction key 2 1 0 9 is for controlling the cursor to the right lower direction, and the fifth direction key 2 1 1 0 is for Control the cursor downward direction 5 brother six squares ask key 2 1 1 1 is to control the cursor to the lower left direction, the seventh direction key 2 1 1 2 is to control the cursor to the left direction, and the eighth direction key 2 1 1 3 is the control The cursor has four control keys and eight control keys in the upper left direction. 12 1309374 On the other hand, the processing unit 1 4 3 processes the button signal of the action into a four-bit organization data packet, and the packet is inside the packet. The device includes a button state signal, an X-axis displacement signal, a Y-axis displacement signal, and a computer page page-draw signal; and when the twelve pointing function buttons are general keyboard functions, the processing unit 1 4 3 is a button signal of the action. Transmitting a corresponding scan code, the scan is caused by the keyboard setting code of the initial setting, and the scan code or the data packet is transmitted to the host bus interface 14 4 through the internal bus 1 4 4, and then the host Bus 1 7 is transmitted to the host 1 5 to perform the The description of the preferred embodiments of the preferred embodiment of the present invention is not limited to the scope of the present invention. The equivalent variations of the present invention and the contents of the drawings are all included in the scope of the present invention, and any person skilled in the art can easily change or modify them in the field of the present invention.
