PURPOSE: To improve the data transmission efficiency of a game machine remote controller by sending a sending pulse after adding inversion information and sending the inversion information after inverting, when bit information requlated by the longer pulse interval of the sending pulse occupies the majority of bit information which comprises operation control information. CONSTITUTION: This remote controller 1 performs encoding processing, etc., on an operation control signal outputted from a key 11 by a microcomputer 12, and sends light from an infrared light emitting diode 13 as an infrared pulse. At this time, transmission data is sent by adding the inversion information. In a game machine 2, a light pulse sent from the remote controller 1 is received by an infrared light receiving diode 21, and it is amplified by a pre-am-plifier 22, and a microcomputer 23 identifies the inversion information based on the pulse interval of a received pulse string. In other words, when the bit information regulated by the "long pulse interval of a sent pulse occupies the majority of the bit information of the operation control information, the inversion information is sent by inverting. |
