INFORMATION PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an information processing device that achieves switching control of a resonance frequency band of an antenna without relying on a radio communication module.SOLUTION: An antenna 1 and a switching circuit 2 are provided inside a display unit 12. The switching circuit 2 switches a connection destination of a signal line 4a led out from a radio communication module 124 provided inside a main body 11 between antenna elements 1a and 1b included in the antenna 1. The switching circuit 2 performs the switching on the basis of a control signal supplied by a signal line 4b led out from an EC/KBC 125 provided inside the main body 11. Software running in the main body 11 regularly performs polling to the radio communication module 124 to obtain an execution state of radio communication, determines whether the antenna elements should be switched, and controls the EC/KBC 125 to supply a control signal to the switching circuit 2.
