ABSTRACT:
Between two units which are separately arranged, a power source signal is supplied from one of the two units to the other unit via electromagnetic induction coupling by using induction coils, and data signals are mutually transmitted and received between both of the units. A change in coupling distance between the induction coils provided for the two units is detected from a signal level of a reception signal from the unit which receives the power supply. When the reception signal level decreases, the signal level of the power supply signal is increased.
