Patent ID: 7355845

Claim:
A portable electronic device having a removable hard disk drive, the portable electronic device comprising: a case having a mounting opening on one side thereof, the mounting opening connected to a mounting space inside the case, thereby providing a passage to the mounting space, and the mounting space having a connector disposed on the bottom of the inside of the mounting space; a hard disk drive slidingly inserted into the mounting space through the mounting opening of the case, and having terminals which become in contact with the connector when the hard disk drive is completely mounted; a power switching unit sensing an operation for attaching or detaching the hard disk drive, thereby cutting off power before detaching the hard disk drive and providing power after mounting the hard disk drive, and a disk cover mounted on the upper part of the hard disk exposed through the mounting opening and having a handle disposed on the surface of the disk cover, wherein on a rear case of the case, inside support plate formed adjacent to the mounting opening and in parallel with the flat surface of the rear case, and supporting the inner surface of the hard disk drive is disposed and a pair of left and right side supports formed from below the inside support plate downward in the direction of mounting the hard disk drive, having an interval a little greater than the width of the hard disk drive between the left and right side supports, thereby supporting both side surfaces of the hard disk drive are disposed, thereby forming the mounting space divided by the inside support plate and the left and right side supports, and wherein a pair of left and right guide ribs having an interval between the ribs tapering from the top to the bottom of the interval are disposed on top of the left and right side supports adjacent to the mounting opening, regulation projections facing each other and formed perpendicularly to the left and right side supports and protruding toward inside, thereby preventing the movement of the hard disk drive in the back and forth direction, are disposed at the bottom of the left and right side supports, and stoppers protruding from the rear case and stopping the hard disk drive at a position where the hard disk drive is completely mounted are disposed on the bottom end of the mounting space.
