  • Patent number: 4023670
    Abstract: An apparatus suitable for use in transporting microfiche master frames, preferably containing microfiche, either from a loading station to an operating station and from the operating station selectively back to the loading station for a repeat transport by said apparatus, or to an exit station. The transport apparatus comprises a feed mechanism for feeding a master frame from the loading station to the operating station, and from the operating station to an elevator. The elevator lifts the master frame which is then selectively ejected from the elevator to either a recycle means or an exit means. The exit means delivers the master frames ejected thereto to an exit station from where the master frames may be removed from the transport apparatus, while the recycle means delivers the master frames delivered thereto back to the loading station from where the master frames are recycled through the transport apparatus.
