<p>PURPOSE:To sufficiently obtain the diameter of a rotary transformer, and to easily regulate the dispersion of inductance between the respective channels of the rotary transformer by respectively forming specific notch parts in a spacer external peripheral part, a rotary transformer external peripheral part, and the internal peripheral surface of a rotary drum external peripheral wall. CONSTITUTION:A torary transformer rotor side 6 is stuck to a spacer 8, and the spacer 8 is fixed to a rotary cylinder 5 by a screw 9, whose head part engages with a notch part 11 provided at the spacer 8. At the external peripheral part of the rotary transformer roter side 6 and at the internal peripheral part of a rotary drum, notch parts 12 and 13 to evade the collision of the head parts of the respective screws 9 are provided. The diameter of the rotary transformer rotor side 6 approximately corresponds to the diameter of the internal peripheral part of the rotary drum 5. Thus, the diameter of the rotary transformer can be sufficiently made larger, and the inductance dispersion between the respective channels of the rotary transformer can be easily regulated.</p> |
