ABSTRACT:
A microfiche carrier has mechanically interlocking features which makes it possible to store a library file of microfiche in a cartridge so that it is not necessary to manually manipulate the individual microfiche. The reader automatically extracts a selected microfiche from a cartridge and then returns it to the vacated cartridge location. The interlocks prevent movement of the reader parts in a sequence which would damage the microfiche while they are out of the cartridge.
