MANUFACTURING APPARATUS OF STORAGE UNIT
A manufacturing apparatus configured to manufacture a storage unit by mounting an object onto a spindle motor that is attached to a housing and configured to rotate the object includes a centering mechanism that includes a first centering unit engaged with a spindle hub of the spindle motor and configured to center the spindle hub, and a second centering unit provided concentric to the first centering part and configured to center the object, and an attachment unit configured to attach the object around the spindle hub while the centering mechanism aligns a center of the spindle hub with a center of the object.
1 . A manufacturing apparatus configured to manufacture a storage unit by mounting an object onto a spindle motor that is attached to a housing and configured to rotate the object, said manufacturing apparatus comprising:
a centering mechanism that includes a first centering unit configured to be engaged with a spindle hub of the spindle motor and to center the spindle hub, and a second centering unit provided concentric to the first centering part and configured to center the object; and
an attachment unit configured to attach the object around the spindle hub while said centering mechanism accords a center of the spindle hub with a center of the object.
2 . The manufacturing apparatus according to claim 1 , wherein the object includes at least two disks each serving as a recording medium, and a spacer provided between the disks and configured to space the disks, and
wherein the manufacturing apparatus includes at least three centering mechanisms and at least three attachment units corresponding to the two disks and the spacer.
3 . The manufacturing apparatus according to claim 2 , further comprising three stations arranged at different positions in parallel,
wherein each station includes a pair of corresponding centering mechanism and attachment unit, and a moving unit configured to move the housing and to stop the housing when the housing is located at a mounting position.
4 . The manufacturing apparatus according to claim 2 , further comprising a spacer cassette that includes a support configured to support the spacer so that the spacer can be taken out, the spacer cassette exposing the spacer at part other than part at which the support contacts the spacer, and the spacer cassette being configured to commonly mounted on the manufacturing apparatus and a cleansing apparatus configured to cleanse the spacer.
5 . The manufacturing apparatus according to claim 4 , wherein the support includes three cylinders used to hold the spacer, each cylinder having a plurality of annular grooves arranged at regular intervals in a longitudinal direction, the spacer being engaged with each annular groove.
