A device comprising: a casing (14, 25) having an interior cavity, an exterior, and an opening, a memory storage unit disposed within the interior cavity of said casing (14, 25), a retractable USB connector electrically connected to said memory storage unit so that data stored in said memory storage unit may be transferred to and from said memory storage unit, and wherein said connector is configured to extend at least partially beyond the opening in the casing (14, 25), a lever having an operating end (21, 31), a joint end, and a pivot point, wherein the lever pivots on a fulcrum (18, 35) at the pivot point, and wherein at least the operating end (21, 31) of the lever is located at the exterior of said casing (14, 25), a rod having a first end and a second end, wherein said first end of the rod is connected to the joint end of said lever, and wherein the second end of said rod is connected to the connector, so that when the lever is pivoted about said fulcrum (18, 35) in one direction, the lever pushes against said rod and said rod pushes the connector through said opening in the casing (14, 25) to a position where at least a portion of the connector extends outside the casing (14, 25), and so that when the lever is pivoted about said fulcrum (18, 35) in another direction, the lever pulls said rod and said rod pulls the connector through said opening in the casing (14, 25) to a position where substantially all of the connector is retracted within the interior cavity of said casing (14, 25), characterised in that the pivot point is between the operating end (21, 31) and the joint end. a casing (14, 25) having an interior cavity, an exterior, and an opening, a memory storage unit disposed within the interior cavity of said casing (14, 25), a retractable USB connector electrically connected to said memory storage unit so that data stored in said memory storage unit may be transferred to and from said memory storage unit, and wherein said connector is configured to extend at least partially beyond the opening in the casing (14, 25), a lever having an operating end (21, 31), a joint end, and a pivot point, wherein the lever pivots on a fulcrum (18, 35) at the pivot point, and wherein at least the operating end (21, 31) of the lever is located at the exterior of said casing (14, 25), a rod having a first end and a second end, wherein said first end of the rod is connected to the joint end of said lever, and wherein the second end of said rod is connected to the connector, so that when the lever is pivoted about said fulcrum (18, 35) in one direction, the lever pushes against said rod and said rod pushes the connector through said opening in the casing (14, 25) to a position where at least a portion of the connector extends outside the casing (14, 25), and so that when the lever is pivoted about said fulcrum (18, 35) in another direction, the lever pulls said rod and said rod pulls the connector through said opening in the casing (14, 25) to a position where substantially all of the connector is retracted within the interior cavity of said casing (14, 25), characterised in that the pivot point is between the operating end (21, 31) and the joint end.
