Abstract
In a remote control system used in a plurality of electronic appliances equipped with radio communication circuits operable within the same frequency band, interference of radio communication between specific electronic appliances can be prevented by employing a shielding apparatus. The remote control system comprises a plurality of electronic appliances equipped with radio communication circuits operable within the same frequency band; and a shielding member arranged between specific electronic appliances among the plural electronic appliances, for shielding a communication signal derived from the communication circuit of another electronic appliance. The shielding member is formed in a transparent plate shape, or a semitransparent plate shape, into which an absorbing agent for absorbing the signal from the communication circuit has been mixed.
