In a communication system that performs recharging operation and short-range data communication between a portable terminal and a cradle, when a communication unit of the cradle is halted for power saving purpose, there is no unit available to activate the communication unit of the cradle through operation of the portable terminal when data communication is commenced while the portable terminal remains placed in the cradle. A first control unit 22 activates a first communication unit 24 according to an output of an open state detection unit 23 that detects an open state of a portable terminal 20. A second control unit 27 activates a second communication unit 26 of the cradle according to an output of an opened terminal detection unit 25 that detects placement of the opened portable terminal 20. As a result, the first communication unit 24 and the second communication unit 26 are activated by opening the portable terminal 20, whereby bidirectional communication can be established therebetween.
