A VTR upper cylinder phase detection device consisting of one non-contact displacement meter installed on the side of the R upper cylinder and at a predetermined distance from the outer periphery of the VTR upper cylinder, provides high positional accuracy for the rotated VTR upper cylinder. A phase detection device for a cylinder on a VTR, characterized in that phase detection is performed by detecting a head chip attached with a non-contact displacement meter. □
