1. A slim-type disc drive, comprising:
a casing having an indentation section that accommodates a CD, and a hole that communicates an inside of the casing with an outside of the;
a hinge cover which is pivotally connected to the casing, and is movable to a closed position in which the hinge cover covers up the indentation section, and is movable to an open position in which the indention section is uncovered, the hinge cover having a projection that passes through the hole, the projection having a free end that is disposed inside of the casing at all times irrespective of whether the hinge cover is in the closed position or the open position; and
an elasticity element which is disposed entirely inside the casing at all times irrespective of whether the hinge cover is in the closed position or the open position, the elasticity element contacting the free end of the projection, the free end receiving an elasticity force from the elasticity element when the hinge cover covers up the indentation section;
wherein the elasticity element is a torsion spring comprising a tail end through which the torsion spring applies the elasticity force onto the free end of the projection.
2. A slim-type disc drive according to claim 1, wherein the casing comprises an upper casing, which is pivotally coupled to the hinge cover, the upper casing having the indentation section and the hole formed thereon.
3. A slim-type disc drive according to claim 2, wherein the upper casing has a first side and a second side, wherein the first side can be covered up by the hinge cover while the second side, which is the rear side of the first side, has the elasticity element disposed thereon.
4. A slim-type disc drive according to claim 3, wherein the casing further comprises a lower casing which is coupled to the upper casing to cover up the second side.
5. A slim-type disc drive according to claim 1, wherein a bump is formed inside the casing and that the elasticity element further comprises a wraparound section through which the torsion spring is wrapped around the bump.
6. A slim-type disc drive according to claim 5, wherein the casing comprises an upper casing, which is pivotally coupled to the hinge cover, the upper casing having the indentation section and the hole formed thereon.
7. A slim-type disc drive according to claim 6, wherein the upper casing has a first side and a second side, wherein the first side can be covered up by the hinge cover while the second side, which is the rear side of the first side, has the bump formed thereon.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An air vent cleaning mechanism comprising:
a blade positioned parallel to and lying substantially on a first side of a vent substrate having a vent opening, the blade moveable parallel to the first side of the vent substrate over the vent opening;
a debris catching mechanism positioned parallel to and lying substantially on a second side of the vent substrate opposite the blade, the debris catching mechanism movable parallel to the second side of the vent substrate over the vent opening, and independently of the blade, wherein the debris catching mechanism includes a free hole area being positionable in line with the vent opening to allow free flowing air to move through the vent opening; and
a sensor for determining when air flow through the vent opening has reached a predetermined rate, the sensor configured to provide a signal to cause the debris catching mechanism to move from a home position away from the vent opening to a deployed position over the vent opening and to cause the blade to move from a home position away from the vent opening to a deployed position over the vent opening, the movement of the blade causing dust or debris on an edge of the vent opening to be scraped off and captured by the debris catching mechanism.
