Abstract
A remote data read system includes a plurality of accumulators including first transmission/reception sections of an electromagnetic induction type, and a handy terminal including a second transmission/reception section of an electromagnetic induction type. The plurality of accumulators accumulate accumulation values representing amounts of consumed power, gas, tap water, or the like, and output accumulated value data in response to data request signals transmitted thereto. The first transmission/reception sections receive external data request signals, and output accumulation value data in response to the data request signal. The handy terminal outputs the data request signal to read an accumulation value from the accumulator and displays input accumulation value data. The second transmission/reception section outputs the data request signal to the first transmission/reception section, and receives the accumulation value data output from the first transmission/reception section.
