Multiple Rotary Picker Assemblies

      A library architecture wherein two independent picker
assemblies move around a cylindrical cartridge carousel which is
either stationary or rotatable provides a higher degree of
independence between the two pickers.

The preferred embodiment of this invention, as illustrated in Figs. 1
and 2, comprises:

o   A cylindrical cartridge carousel 1 suspended to a stationary
    frame 2 by a shaft 3 aligned with the carousel center line.

o   A rotatable platform 4 which can be rotated around the shaft 3 by
    a motor 5.  Platform 4 is mounted to shaft 3 via a hollow shaft 6
    through which shaft 3 is inserted.

o   Independent picker assemblies 7 which are mounted to shaft 6 and
    rotate around it.  Each picker assembly is driven by its own
    motor mounted to platform 4.  The pickers move in tangential and
    axial directions to reach any point on the carousel 1.  During
    normal operations, the platform 4 remains still while the pickers
    7 are in action.  If one of the picker assemblies is out of
    action but can still be moved freely, the other picker can push
    it away to gain access to any cartridge cell.  However, if it is
    locked up, the platform 4 takes over and moves the locked picker
    assembly away.  It is obvious that the carousel 1 can be make
    movable while the platform 4 becomes stationary to gain the same
    effect.
