Abstract
Abstract The present invention relates generally to microfiche types of microfilm strip holders and more particularly to microfilm strip holders adapted for use in a fanning type magnetic file tray system. An embodiment of the invention illustrated in the drawings comprises front and rear rectangular panels of transparent and flexible synthetic plastic material, commonly referred to as a microfiche master, which provides a plurality of horizontal pockets for receiving microfilm strips. At least one of these pockets has mounted therein a magnetic strip, the opposite extremities of which terminate adjacent the vertical edge portions of the microfiche master or holder in position for cooperation with the magnets of a filing tray, to effect fanning apart of the upper margins of a predetermined group of holders.

Claim 1
Independent Claim
154 words
A microfilm strip holder adapted for use in a fanning magnetic filing tray system, said holder comprising two substantially rectangular panels of relatively thin, transparent plastic sheet material, elongate spacer strips secured between said panels providing a plurality of vertically disposed horizontally extending elongate pockets presenting open extremities at one end thereof for receiving microfilm strips, and one piece magnetic strip within at least one of said pockets and including a narrow strip section of a width conforming substantially with the width of said spacer strips and adhesively secured to both adjacent panels and terminating in plate-like sections each of a width substantially equal to the width of the pocket in which it is enclosed and being located adjacent opposite extreMities of the enclosing pocket in position for cooperation with a complementary magnetequipped filing tray, to effect fanning apart of the upper margins of a group of such holders in a complementary magnet-equipped tray.
Claim 2
Dependent Claim

A microfilm strip holder adapted for use in a fanning magnetic filing tray system, said holder comprising two substantially rectangular panels of relatively thin, transparent plastic sheet material, elongate spacer strips secured between said panels providing a plurality of vertically disposed horizontally extending elongate pockets presenting open extremities at one end thereof for receiving microfilm strips, and one piece magnetic strip within at least one of said pockets and including a narrow strip section of a width conforming substantially with the width of said spacer strips and adhesively secured to both adjacent panels and terminating in plate-like sections each of a width substantially equal to the width of the pocket in which it is enclosed and being located adjacent opposite extreMities of the enclosing pocket in position for cooperation with a complementary magnetequipped filing tray, to effect fanning apart of the upper margins of a group of such holders in a complementary magnet-equipped tray.
Claim 3
Dependent Claim
164 words
A microfilm strip holder adapted for use in a fanning magnetic filing tray system, said holder comprising two substantially rectangular panels of relatively thin, transparent plastic sheet material, elongate spacer strips secured between said panels providing a plurality of vertically disposed horizontally extending elongate pockets presenting open extremities at one end thereof for receiving microfilm strips, and magnetic strip means within at least one of said pockets and including a narrow strip section of substantially the width of a spacer strip to serve as such in the enclosing pocket and terminating in the lower margins of plate-like end sections of substantially the width of the enclosing pocket and adhered to one adjacent panel leaving the open extremity thereof accessible to receive a microfilm strip of a length to be exposed between the plate-like sections which are in position for cooperation with a complementary magnet-equipped filing tray, to effect fanning apart of the upper margins of a group of such holders in a magnet-equipped tray.
