A tray mechanism for a device housing includes a tray bed having a planar surface with first and second opposing sides that form a boundary around the planar surface, wherein the first opposing sides include a front side and a back side, wherein the front side is configured with dimensions for closing an opening of a cavity within the device housing, and wherein the second opposing sides are configured for a slideable attachment within the cavity of the device housing. The tray mechanism further includes a lever positioned on the planar surface of the tray bed and a hinge mechanism that pivotally connects the lever to the planar surface of the tray bed. A method for operating the tray mechanism includes a convex side of the lever rolling against the device housing as the lever rotates to eject the tray bed pivotally connected to lever from the device housing.
