A receiver defines at least one cell for receiving the at least one cartridge, and a passageway extends longitudinally along the center of the receiver to an opening defined in an external surface of the receiver. Springs are employed for biasing the at least one cartridge in a first position in the at least one cell wherein the cavity is not aligned with the passageway, or in a second position in the at least one cell wherein the cavity is aligned with the passageway. In one application, the storage device is adapted for storing bits in a multi-bit screwdriver. ## Claims ### Claim 1 A storage device comprising: one or more cartridges, each cartridge defining a respective cavity of one or more cavities for receiving a respective storage item of one or more storage items, the one or more cartridges further defining a slot;

and a locking mechanism for securing the selected bit at an end of the tubular shaft. ### Claim 10 (depends on 1) The storage device of claim 1 wherein the one or more storage items comprise one or more bits having a head portion and a base portion, the base portion defining a plurality of sides, and wherein the storage device further comprises: a tubular shaft extending from the opening in the storage device for receiving from one of the one or more cavities a selected bit of the one or more bits, wherein the tubular shaft defines an interior portion having a plurality of lands corresponding in number to the plurality of sides of the base portion of the one or more bits, the interior portion having an entry end proximate to the opening in the storage device, and an exit end opposing the entry end, and wherein the lands are smaller at the entry end than at the exit end, and substantially conform to the shape of the base portion of the selected bit at the exit end; and a locking mechanism for securing the selected bit at the exit end of the tubular shaft. ### Claim 11 (depends on 1) The storage device of claim 1 wherein the one or more storage items comprise one or more bits, of the one or more bits having a head portion and a base portion, the base portion defining a plurality of concave sides, and wherein the storage device further comprises: a tubular shaft extending from the opening in the storage device for receiving from one of the one or more cavities a selected bit of the one or more bits, wherein the tubular shaft defines an interior portion having a plurality of lands corresponding in number to the plurality of sides of the base portion of the one or more bits, the interior portion having an entry end proximate to the opening in the storage device, and an exit end opposing the entry end, and wherein the lands are smaller at the entry end than at the exit end, and substantially conform to the shape of the base portion of the selected bit at the exit end; and a locking mechanism for securing the selected bit at the exit end of the tubular shaft. ### Claim 12 (depends on 1) The storage device of claim 1 wherein the one or more storage items comprise one or more bits, of the one or more bits having a head portion and a base portion, the base portion defining a plurality of concave sides, the sides being conically canted toward the head portion, and wherein the storage device further comprises: a tubular shaft extending from the opening in the storage device for receiving from one of the one or more cavities a selected bit of the one or more bits, wherein the tubular shaft defines an interior portion having a plurality of lands corresponding in number to the plurality of sides of the base portion of the one or more bits, the interior portion having an entry end proximate to the opening in the storage device, and an exit end opposing the entry end, and wherein the lands are smaller at the entry end than at the exit end, and substantially conform to the shape of the base portion of the selected bit at the exit end;
