PROBLEM TO BE SOLVED: To make it possible to appropriately execute radio communication between frames.SOLUTION: A mobile phone 10 comprises a first frame 12a, second frame 12b, and the like connected by a slide mechanism. First to third communication units are installed inside the first frame 12a; and a fourth communication unit is installed inside the second frame 12b. Data is transmitted/received between each of the first to third communication units and the fourth communication unit by short-range radio communication. The fourth communication unit transmits a confirmation signal at predetermined intervals, and radio field strength is recorded when the first communication unit receives the confirmation signal. On the basis of the radio field strength, a communication unit for communication for communicating with the fourth communication unit is set. |
