Abstract:
PROBLEM TO BE SOLVED: To provide a slip ring device which improves noise resistance.SOLUTION: The slip ring device includes: a shaft body that is rotatable around an axis; an electrode ring group including a plurality of electrode rings each being formed from a ring-shaped conductor and fixed to the shaft body so as to surround the shaft body; a brush group including a plurality of brushes each being formed from a conductor and disposed so as to be brought into contact with the plurality of electrode rings; and a plurality of insulators which are separated from each other in a length direction of the shaft body and provided so as to hold the electrode ring group and the brush group therebetween. The brush group is formed from a signaling brush to which a desired signal is transmitted and a shielding brush which is disposed proximately to the signaling brush and of which the voltage is fixed. The electrode ring group is formed from a signaling electrode ring that can be brought into contact with the signaling brush, and a shielding electrode ring which is disposed proximately to the signaling electrode ring and can be brought into contact with the shielding brush.SELECTED DRAWING: Figure 1
