PURPOSE:To provide a equipment with which both the protocols of an ASK system and an IrDA system are automatically identified and switched without fail. CONSTITUTION:The light received by a light receiving part 10 of a system A is decoded by a demodulating/decoding part 14 of the system A. The light received by a light receiving part 11 of a system B is decoded by a demodulating/decoding part 15 of the system B. A control part 19 controls a switching part 18, analyzes a packet transmitted from either the demodulating/ decoding part 14 of the system A or the demodulating/decoding part 15 of the system B and drives a light emitting part 12 of the system A while using a coding/modulating part 16 of the system A corresponding to the protocols of the respective systems or drives a light emitting part 13 of the system B while using a coding/modulating part 17 of the system B. |
