Safety ensuring device and disc apparatus utilizing the same

A disc apparatus, comprising:

• a base;
• a lid pivotably attached to the base, the lid being rotatable around a rotating axis, the lid forming a protrusion next to the rotating axis;
• a spindle motor configured for driving a disc to rotate at a predetermined speed;
• and
• a circuit board enclosed in the base and electrically coupled to the spindle motor, the circuit board including a first switch, a second switch, a first controller, and a second controller, the first switch and the second switch being simultaneously operable by the protrusion of the lid and respectively connecting to the first controller and the second controller, the first controller and the second controller mutually independently controlling rotation of the spindle motor based on signals transmitted from the first controller and the second controller.

A disc apparatus comprising:

• a base defining an opening therein;
• a lid pivotably attached to the base, the lid forming a protrusion positioned corresponding to the opening, the lid being pivotable between a covered position for covering the base, and an opened position for uncovering the base;
• a spindle motor receiving in the base and configured for driving rotation of a disc;
• and
• first and second switches positioned in the base and accessible from the opening, wherein when the lid is positioned at the covered position, the protrusion extends into the opening and simultaneously presses the first and second switches so as to turn on the spindle motor, when the lid is rotated from the covered position toward the opened position, the first switch and the second switch are simultaneously released so as to turn off the spindle motor;
• wherein the first switch includes a first pressing portion, the second switch includes a second pressing portion, the first pressing portion and the second pressing portion are positioned at distinct positions along a front-to-back direction of the base, and the protrusion forms a first activating surface and a second activating surface in a manner so as to be able to simultaneously press and release the first pressing portion and the second pressing portion, respectively.
