ELECTROMAGNETIC WAVE SHIELDING DEVICE OF A ROTARY STRUCTURE

摘要

An electromagnetic wave shielding device of a rotary structure is provided to prevent an erroneous operation of a peripheral device and increase a communication security from a tapping device. An electromagnetic wave shielding device of a rotary structure includes an electromagnetic wave shielding gasket(60) and an elastic unit(70). The electromagnetic wave shielding device has a bottom supporting body(40) and a top rotary body(10) connected to the bottom supporting body for performing a relative rotational movement. One side of the electromagnetic wave shielding gasket is fixed to one of a periphery of the bottom supporting body and a periphery of the top rotary body and the other side of the electromagnetic wave shielding gasket is the other of the periphery of the bottom supporting body and the periphery of the top rotary body. The elastic unit applies elastic force to allow the electromagnetic wave shielding gasket to be in contact with the other end of the periphery of the bottom supporting body and the periphery of the top rotary body.
