ABSTRACT:
A power feeding device for VTR rotating drums coaxially provided on an end face of a rotating drum, which has magnetic heads in the vicinity of the outer circumferential surface thereof and is rotatably provided coaxially with a stationary drum, adapted to feed power to electronic components incorporated in the rotating drum, in which slits are provided on the slip rings making sliding contact with power feeding brushes in parallel with the axial line of the slip rings. Two slip rings are fixedly fitted to a rotating shaft made of an electrically conductive material in the axial direction in a mutually insulated state, and power is fed to the electronic components from the slip ring on the side remoter from the rotating drum via the rotating shaft.
