Abstract
An infrared signal transmitting apparatus provided by the present invention comprises an infrared light emitting device for transmitting high-speed signals, a plurality of infrared light emitting devices for transmitting low-speed signals which are distributed and laid out in such a way that, as a whole, a wide directivity is obtained, a high-speed-signal driving circuit for driving the infrared light emitting device for transmitting high-speed signals in accordance with a high-speed signal (data signal) received from a computer, a low-speed-signal driving circuit for driving the plural infrared light emitting devices for transmitting low-speed signals at the same time in accordance with a low-speed signal (remote-control signal) received from the computer, and logic means for allowing the high-speed-signal driving circuit to drive the infrared light emitting device for transmitting high-speed signals in accordance with the low-speed signal. When a remote-control signal is received from the computer, not only do the infrared light emitting devices for transmitting low-speed signals each transmit an infrared signal, but the infrared light emitting device for transmitting high-speed signals also outputs an infrared signal as well.
