摘要：
A communications device includes: an IrDA frame detecting section 202, an IrSimple frame detecting section 201, and a transfer rate control section 230. The IrDA frame detecting section 202 detects a first predetermined frame based on pulses detected in an incoming response signal at first predetermined intervals. The IrSimple frame detecting section 201 detects a second predetermined frame based on pulses detected in the incoming response signal at second predetermined intervals. The transfer rate control section 230 determines that the transfer rate of the response is equal to the first transfer rate if the IrDA frame detecting section 202 detects the first predetermined frame and determines that the transfer rate of the response is equal to the second transfer rate if the IrSimple frame detecting section 201 detects the second predetermined frame.
