Abstract: PROBLEM TO BE SOLVED: To provide a small-sized radio communication device which improves convenience for operations by using an antenna that a user does. SOLUTION: This small-sized radio communication device performs processing that the user requests by executing application software. This small-sized radio communication device is equipped with a rod type antenna which extends in a specific direction and at least partially can be drawn out of or stored in the housing of the small-sized radio communication device, a 1st detector which detects position change of the antenna in the specific direction, and a 2nd detector which detects variation in the angle of rotation of the antenna rotated on an axis along the specific direction. The position change and variation in the angle of rotation that the 1st and 2nd detectors detect select correspond to two operations that the user does as to the application software.
