Input/Output Port for Automatic Cartridge Tape Library

       Disclosed is the design of a device to function as an
input and/or output port to permit insertion or removal of cartridges
to/from an automatic cartridge tape library.

      The port is mounted in a storage wall of the library. Cells
within the port may be accessed by a human operator outside the
library or by the automatic accessor within the library.  A single
port may function as an input port, or an output port, or it may be
assigned "dynamically" by the library manager.  Cartridges may be
arranged in a vertical stack or on edge, side-by-side, as books on a
shelf. Cartridges may or may not be separated by separators.

      The port has a door which may take one of several forms:
1.  A segment of a hollow cylinder with an opening in it at least
large enough to allow a cartridge to be inserted to or removed from
the interior of the cylinder (Figure 1).
2.  A hollow prismatic polygon with an opening in the side at least
large enough to allow a cartridge to be inserted to or removed from
the interior of the polygon.
3.  A flexible membrane which is guided in a track to move around the
periphery of the port.
4.  A segmented door composed of slats similar to a roll-top desk
which is guided by tracks to move around the periphery of the port
(Figure 2).

      In each instance the motion of the door is circumferential to
the common axis of the cartridges.  In each instance, the door
subtend...
