上記回転ヘツドの上下動を規制させるように構成
したことを特徴とする回転ヘツド装置。[Claims for Utility Model Registration] An upper fixed drum, a lower fixed drum, a rotating disk disposed between them, and a rotating disk attached to the outer periphery of the rotating disk between the upper fixed drum and the lower fixed drum. A rotary head device comprising a rotary head inserted into an annular gap, wherein a cylindrical outer circumferential rib is integrally provided on the outer circumference of the rotary disk, and a head insertion portion is provided that penetrates the outer circumferential rib in the radial direction, The rotary head is inserted into the gap by passing through the head insertion portion, and a first annular step portion is provided inside the lower end surface of the outer periphery of the upper fixed drum, facing the upper surface of the outer periphery of the rotary disk; A second annular step portion is provided inside the upper end surface of the outer periphery of the lower fixed drum and is opposed to the lower end surface of the outer periphery rib of the rotary disk.
A rotary head device characterized in that the vertical movement of the rotary head inserted into the gap is restricted by a second stepped portion.
