| 摘要 |
The present invention relates to a transmission angle adjusting device which comprises a first transmission device and a second transmission device disposed on the computer and the keyboard respectively. Each of the first and the second transmission device has an infrared transmitter, an infrared receiver and a transmission angle/direction adjusting device arranged between the transmitter and the computer (or the keyboard) or disposed between the receiver and the keyboard (or the computer). Since the transmission angle/direction adjusting device can adjust the transmission angle of the infrared transmitter, transmission signals from these adjacent arranged transmission device can be separated from each other in order to prevent interference. |
