Claims

[Claims for Utility Model Registration] A tape guide having a first rotating magnetic head that rotates in a first plane, and a second rotating magnetic head that rotates in a second plane that is higher than the first plane. In the drum device, the first rotating magnetic head is attached to a lower rotating drum body, the second rotating magnetic head is attached to an upper rotating drum body, and the lower rotating drum body abuts a flange member fixed to a rotating shaft. are positioned in contact with each other in the height direction,
The tape guide drum device is configured such that the rotating drum body is positioned upward in the height direction by contacting the upper surface of the outer peripheral side of the lower rotating drum body.
