ABSTRACT:
A microfiche reader and/or enlarger has a housing provided with an opening. The microfiches are stored in hard-cover files having a pair of covers between which a series of pockets is located, with the individual pockets being connected to one another and the two end pockets each being connected to one of the covers. When the covers are moved from parallel to coplanar position the pockets assume a fan-shaped outline; when the file is attached to the opening in this position with the pockets projecting into the housing, inner open ends of the pockets are accessible to a gripper on a pivot arm which can be moved opposite any selected one of the open ends. The gripper can then extract the microfiche from the selected pocket and subsequently reinsert it thereinto.
