| 摘要 |
The invention relates to an optical mouse, comprising a base unit, a transmitter and a receptor installed in the base unit to obtain coordinates, a transparent or semi-transparent sensing board that is installed above the transmitter and the receptor, and an accommodating chamber to accommodate the sensing board. The sensing board is capable of movement, front and back, left and right, inside the accommodating chamber, so designed that the signals transmitted from the transmitter are reflected by the sensing board back to the receptor to measure its coordinates. Then, whenever there is any movement of the sensing board, the change of movement is calculated to indicate the movement of cursor, so that the optical mouse can be used to move the cursor.
