イスククランプ。 In a disk clamp for a disk-type information processing device in which an information recording disk is held and rotated between a disk table and a disk holder,
A center pin having an outer diameter equal to the inner diameter of the center hole of the hub of the hub-equipped disk is concentrically fixed to the disk table, and the outer circumferential portion is in the shape of a truncated cone and the cross-sectional diameter of the center pin is fixed concentrically to the disk table. A truncated cone having a center ring whose part is equal to the inner diameter of the center hole of the hubless disk so as to be able to slide up and down concentrically, and which can be brought into close contact with the outer peripheral upper edge of the hub of the hub-equipped disk, on the disk holder. 1. A disk clamp characterized in that a concave portion having the shape of a shape is provided concentrically, and a center guide that can be vertically and slidably fitted to the center pin is fitted into the concentrically concentrically movable vertically slidable portion.
