PURPOSE:To enable data exchange between electronic equipments without any cable by sending a signal generated from a signal generator in a 1st electronic equipment toward a signal detection means in a 2nd electronic equipment installed closely at a prescribed distance directly, detecting the transmission signal by a signal detection means and connecting the result to the 2nd electronic equipment. CONSTITUTION:A signal is directly radiated from a signal generating means 50 of the 1st electronic equipment 10 not through any cable to a signal detection means 60 of the 2nd electronic equipment 20 installed closely at a prescribed distance, the signal detection means 60 detects the radiation signal to obtain a reception signal. That is, for example, an electric signal is converted into an infrared-ray by the signal generating means 50 and radiated toward the signal detection means 60, which detects the infrared ray and converts it into an electric signal to attain data transmission. Thus, data exchange without any cable is attained. |
