Abstract
A hinged flap including an angled surface and a flat surface prevent the incorrect loading of a 3592 data cartridge into a dedicated pass-through slot. The angled surface of the hinged flap is pushed by a recessed angled surface in the front face of the 3592 data cartridge to force the hinged flap out of the slot, allowing the cartridge to be inserted. In the absence of the recessed angled surface in the front face of the data cartridge, the flat surface of the flap blocks insertion of the data cartridge.
Claims20
A mechanism for preventing incorrect loading of a data cartridge into a cell in an input/output station, the cartridge having a front face with a recessed angled surface, and the cell having a bottom surface facing a cavity adapted to receive the cartridge, comprising:
- a hinged flap placed within the bottom surface of the cell and mounted to the bottom surface at a rotatable first end, and a second end incorporating a first flat surface substantially orthogonal to the bottom surface, the hinged flap including a ramp surface, and a second, angled flat surface between the first flat surface and the ramp surface, wherein:
- the second, angled flat surface forms an angle φ with the bottom surface as measured at a vertex formed by the second flat surface and the bottom surface, the angle φ corresponding to an angle of the recessed angled surface of the cartridge to force the hinged flap toward the bottom surface of the cell.
A system for manipulating data cartridges including a mechanism for preventing incorrect loading of a data cartridge into a cell in an input/output station, said cartridge having a front face with a recessed angled surface and said cell having a bottom surface facing a cavity adapted to receive the cartridge, comprising:
- a hinged flap placed within the bottom surface of the cell and mounted to the bottom surface at a pivotable first end, and a second end incorporating a first flat surface substantially orthogonal to the bottom surface, the hinged flap including a ramp surface, and a second, curved surface between the first flat surface and the ramp surface, wherein:
- the second, curved surface forms an angle φ with the bottom surface as measured at a vertex formed by the second flat surface and the bottom surface, the angle φ corresponding to an angle of the recessed angled surface of the cartridge to force the hinged flap toward the bottom surface of the cell;
- and
- a leaf spring in mechanical communication with the pivotable first end of the hinged flap to rotate the hinged flap.
A method of manufacturing a mechanism for preventing incorrect loading of a data cartridge into a cell in an input/output station, the cartridge having a front face with a recessed angled surface, and the cell having a bottom surface facing a cavity adapted to receive the cartridge, comprising:
- providing a hinged flap placed within the bottom surface of the cell and mounted to the bottom surface at a rotatable first end, and a second end incorporating a first flat surface substantially orthogonal to the bottom surface, the hinged flap including a ramp surface, and a second, angled flat surface between the first flat surface and the ramp surface, wherein:
- the second, angled flat surface forms an angle φ with the bottom surface as measured at a vertex formed by the second flat surface and the bottom surface, the angle φ corresponding to an angle of the recessed angled surface of the cartridge to force the hinged flap toward the bottom surface of the cell.
