PROBLEM TO BE SOLVED: To accelerate communication by preventing interference in a transmitter/receiver. SOLUTION: An information processing unit comprises a transmitter, having an infrared emitting diode and a receiver having a photodiode. In this case, the transmitter and the receiver are disposed separately at its distance. Since the transmitter and the receiver do not interfere with each other, full dual communication can be executed. A plurality of the transmitter and a plurality of the receivers are provided, data are divided, and further the communication can be accelerated. Furthermore, the transmitter and the receiver are surrounded by a partition, so that transmitting lights do not be interfered with each other. |
