description PROBLEM TO BE SOLVED: To provide an infrared data transmission device for preventing a circuit scale from increasing even if the amount of data to transmit continuously becomes large. SOLUTION: The infrared data transmission device includes: a data buffer (17) for correlating unit transmission data segmented into prescribed units to a flag bit indicating whether a prescribed flag indicating a segment of a transmission packet should be transmitted for storage; a DMA circuit (18) for storing the unit transmission data into the data buffer (17); transmission parts (14, 15, 16, 20) for transmitting the unit transmission data as an infrared signal; and a transmission control circuit (19) for correlating the flag bit set to be in an effective state to the unit transmission data to be transmitted for recording, and performing control on whether the prescribed flag should be transmitted based on whether the flag bit corresponding to the unit transmission data read by the transmission parts (14, 15, 16, 20) is in an effective state. The transmission parts (14, 15, 16, 20) transmit the prescribed flag after the transmission of the unit transmission data when the flag bit is in an effective state. COPYRIGHT: (C)2011,JPO&INPIT
