Zusammenfassung:	A microfiche having one or more frames to be deleted is mounted in accurate registration and alignment on a microfiche deck, and a light is energized in the deck underneath each frame of the microfiche to be deleted. The operator then moves a knife carriage mounted on an "X-Y" detented slide system and having a solenoid-operated knife blade, on top of the microfiche, to the proper position with respect to each frame to be deleted, and then energizes the solenoid to cut that frame from an adjacent frame on the same filmstrip. After each edge of the frame is cut, the operator uses a spatula to pry up an end of the frame which is then grasped and stripped off of the microfiche. After all of the unwanted frames are deleted, the microfiche is removed from the deck.
