PROBLEM TO BE SOLVED: To avoid radio interference without adding a circuit for judging the degree of the radio interference.SOLUTION: A communication device 11 (device B) which communicates with radio equipment 12 (device A) located in a close range includes: close range judgment means (control unit 110, sensor units 111, 121, short-range radio communication units 112, 121) for judging whether or not the radio equipment approaches within a predetermined distance; and radio frequency interference avoidance means (control unit 110) for avoiding radio interference with the radio equipment. The radio frequency interference avoidance means controls to avoid radio interference with the radio equipment when the close range judgment means judges that the radio equipment approaches nearer than the predetermined distance. |
