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, a lower rotary drum body to which the first rotary magnetic head is attached and an upper rotary drum body to which the second rotary magnetic head is attached are arranged such that the flange portions projecting toward the inner periphery are diametrically upward. The lower rotary drum body and the upper rotary drum body are positioned in common in the height direction by abutting on a flange member fixed to the rotating shaft with the respective flange portions staggered in the circumferential direction. A tape guide drum device with the following configuration.
