The HDD filler has a frame body, a pivot axis, and a rotating device; wherein the frame body defines a bottom surface and a top surface which corresponds to the bottom surface. The pivot axis is disposed in the frame body. One end of the rotating device is pivoted to the pivot axis, such that the rotating device can rotate due to gravity to stay within or be partly exposed to the frame body. If the frame body is installed into the case while the bottom surface is upward, the rotating device rotates along the pivot axis and is guided by gravity such that part of the rotating device is exposed to the frame body to stop the installation. ## Claims ### Claim 1 A hard disk drive filler detachably installed in a case, the hard disk drive filler comprising: a frame body defining a bottom surface and a top surface corresponding to the bottom surface; a pivot axis located in the frame body; and a rotating device; one end of the rotating device is pivoted to the pivot axis such that the rotating device can rotate due to gravity to stay within or be partly exposed to the frame body; whereby, if the hard disk drive filler is installed into the case when the bottom surface is upward, the rotating device is guided by gravity to rotate along the pivot axis, until a part of the rotating device is exposed to the frame body to block the frame body and keep it outside the case. ### Claim 2 (depends on 1) The hard disk drive filler as claimed in claim 1, wherein the hard disk drive filler further comprises a hole; the hole is located on the top surface and on a rotating path of the rotating device for allowing an end part of the rotating device to be exposed to the frame body. ### Claim 3 (depends on 2) The hard disk drive filler as claimed in claim 2, wherein the top surface can be represented as an open space, and the hole is the open space. ### Claim 4 (depends on 1) The hard disk drive filler as claimed in claim 1, wherein if the hard disk drive filler is installed in the case when the top surface is upward, the rotating device is guided to rotate to stay within the frame body without being exposed due to gravity. ### Claim 5 (depends on 1) The hard disk drive filler as claimed in claim 1, wherein a gravity line is defined by a position of the pivot axis and two rotating areas are separated by the gravity line. ### Claim 6 (depends on 5) The hard disk drive filler as claimed in claim 5, wherein the hard disk drive filler further comprises a stopper located in a position which is equivalent to a position of the gravity line or a position shifted towards the inside; when the rotating device is guided to rotate to an appropriate position in the frame body by the gravity, the rotating device is blocked by the stopper. ### Claim 7 (depends on 6) The hard disk drive filler as claimed in claim 6, wherein a position of the hole is equivalent to the position of the gravity line or the position shifted towards the inside, and opposite to the stopper while the pivot axis is disposed between the hole and the stopper, and the hole and the stopper form a restricting rotating area of the rotating device. ### Claim 8 (depends on 7) The hard disk drive filler as claimed in claim 7, wherein the largest rotating angle of the restricting rotating area of the rotating device is substantially smaller than 180°. ### Claim 9 (depends on 7) The hard disk drive filler as claimed in claim 7, wherein the largest rotating angle of the restricting rotating area of the rotating device is substantially smaller than 160°.
