Abstract:
1. A disk device comprising: a driving unit that is disposed in a housing and that moves between a withdrawal position and a driving position along a plane that is parallel to a surface of a disk that is positioned in the housing, the driving unit being spaced apart from an outer peripheral edge of a disk that is positioned in the housing when the driving unit is in the withdrawal position, and the driving unit being at a position where the disk is rotationally driven by the driving unit when the driving unit is in the driving position; a restricting mechanism that moves between a restriction position and a restriction-removed position, the restriction position being where the movement of the driving unit at the withdrawal position toward the driving position is restricted, the restriction-removed position being where the driving unit at the withdrawal position is allowed to move toward the driving position; and a driving member that is disposed in the housing and that is moved by the power of a motor, wherein a moving force of the driving member moves the driving unit between the withdrawal position and the driving position and moves the restricting mechanism between the restriction position and the restriction-removed position; wherein the driving unit moves from the withdrawal position to the driving position with a base portion of the driving unit being a rotational fulcrum, wherein the restricting mechanism comprises a restricting convex portion and a restricting protrusion, the restricting convex portion being provided at a free end side of the driving unit, the restricting protrusion moving between the restriction position opposing the restricting convex portion and the restriction-removed position separated from the restricting convex portion, and wherein the restricting protrusion obstructs the restricting convex portion to restrict the movement of the driving unit toward the driving position; the disk device further comprising a movable guide having a movable guide edge that engages with the free end side of the driving unit and guides the free end side of the driving unit when the driving unit moves between the withdrawal position and the driving position, wherein the restricting protrusion moves between the restriction position and the restriction-removed position through a link mechanism that operates the movable guide.
