Claims

[Claims for Utility Model Registration] A fixed drum; a rotating drum above the fixed drum; The magnetic head is composed of two sets of rotating magnetic heads arranged at predetermined angular intervals and arranged in the axial direction of the rotating drum and at different heights, A rotating magnetic head device for guiding travel, wherein height adjustment mechanisms for adjusting the heights of the rotating magnetic heads are configured to support one rotating magnetic head and be positioned above and below in the axial direction of the rotating drum. arranged in holes provided at two locations on the rotating drum corresponding to each of the supporting members attached to the rotating drum,
and a support on the adjustment side so that an adjustment tool for adjusting the height adjustment mechanism can reach each height adjustment mechanism from either the upper surface or the lower surface of the rotating drum and enable height adjustment. By forming in the member a hole corresponding to the height adjustment mechanism acting on this support member and a hole corresponding to the height adjustment mechanism acting on other support members, each height adjustment mechanism can be adjusted to the height adjustment mechanism of the rotating drum. The hole configured to communicate with one side and corresponding to the height adjustment mechanism that acts on the support member serving as the adjustment side is larger than the maximum diameter of the adjustment tool that adjusts this height adjustment mechanism, and is A rotating magnetic head device characterized in that the diameter is smaller than the outer diameter of the mechanism.
