Abstract:
PROBLEM TO BE SOLVED: To provide a slip ring device capable of transmitting a signal at a high speed with an inexpensive and small configuration.SOLUTION: The slip ring device includes: a brush (1) electrically connected to a first external terminal; and a ring (2) that is inserted into and fixed to a rotation shaft (4), is disposed slidably with the brush, and is electrically connected to a second external terminal. The slip ring device includes an angle detector (10) that is disposed in the rotation shaft and detects the rotation angle of the rotation shaft.
