PROBLEM TO BE SOLVED: To reduce the number of parts as well as the space by providing a rotary body comprising a piece which is to be detected and a detector in addition to a slip ring part while a rotation detecting means and a slip ring are made into a unit. SOLUTION: A detection/communication part 52 is housed in an upper casing 53a while a slip ring part 51 is housed in a lower casing 53b. The control system for a slip ring unit comprises a host computer for collectively controlling the entire electronic part attaching device 1, the detection/communication part 52 for a slip ring unit 44, various motors including a stepping motor, and motor drivers for driving the motors. The slip ring part 51 which supplies a driving electric-power to various motors on a rotary table side and the detection/ communication part 52 where a control signal is inputted/outputted while the rotation of the rotary table is detected are made into a unit. |
