DATA COMMUNICATION APPARATUS |
摘要 |
A data communication apparatus according to the present invention can be used both in one-wave mode and two-wave mode, and includes: first and second tuning circuits (1, 2); a power supply circuit (3) connected to first tuning circuit (1) for generating power by a signal received by first tuning circuit (1); an information processing circuit (15) connected to firs t tuning circuit (1) or second tuning circuit (2) through a switching circuit (6) and including a detection circuit (7), a decoder (8), an encoder (10) and th e like. Information processing circuit (15) includes a switch control circuit (14) detecting if the mode of the received radio wave is one-wave mode or two-wave mode in accordance with an output from first tuning circuit (1) and controlling switching circuit (6) such that detection circuit (7) is connected to one of first and second tuning circuits (1, 2).
