Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
257 words
An assessory to permit a viewer designed for reel film to be converted to a microfiche viewer, and back again, said viewer including a projection apparatus having predetermined optical axis; spindles removably supporting supply and take-up reels for said film on either side of said viewer optical axis whereby said film may be advanced across said optical axis for viewing thereof, the combination comprising a. a base member having spacer sockets for receiving said spindles whereby to enable said base to be mounted in operative position on said viewer in place of said film reels, said base member having a cylinder portion adapted to support a grid system in operative Relationship to said optical axis; b. a pivot member rotatably mounted on said base member for accurate movement over said cylinder portion of said base member about a predetermined axis substantially concentric with said cylinder portion, said pivot axis laying within the confines of said base member and, c. a traverse means slidably mounted on said pivot member and having a gripping means such that a microfiche held by such gripping means may be drawn across said optical axis for viewing thereof in a direction substantially traverse to said arcuate movement along a line parallel to but spaced apart from said pivot member axis, said traverse means being movable independently of the movement of said pivot member and said traverse means including a pointer disposed in operative relation to said grid whereby to enable the selective positioning of an image on said microfiche in said optical axis.
Claim 2
Dependent Claim
257 words
An assessory to permit a viewer designed for reel film to be converted to a microfiche viewer, and back again, said viewer including a projection apparatus having predetermined optical axis; spindles removably supporting supply and take-up reels for said film on either side of said viewer optical axis whereby said film may be advanced across said optical axis for viewing thereof, the combination comprising a. a base member having spacer sockets for receiving said spindles whereby to enable said base to be mounted in operative position on said viewer in place of said film reels, said base member having a cylinder portion adapted to support a grid system in operative Relationship to said optical axis; b. a pivot member rotatably mounted on said base member for accurate movement over said cylinder portion of said base member about a predetermined axis substantially concentric with said cylinder portion, said pivot axis laying within the confines of said base member and, c. a traverse means slidably mounted on said pivot member and having a gripping means such that a microfiche held by such gripping means may be drawn across said optical axis for viewing thereof in a direction substantially traverse to said arcuate movement along a line parallel to but spaced apart from said pivot member axis, said traverse means being movable independently of the movement of said pivot member and said traverse means including a pointer disposed in operative relation to said grid whereby to enable the selective positioning of an image on said microfiche in said optical axis.
Claim 3
Dependent Claim
34 words
The accessory of claim 1 wherein said base includes a cylinder portion which along with said roof member defines a tunnel through which a microfiche is guided into and out of the imaging station.
Claim 4
Dependent Claim
51 words
The accessory of claim 2 wherein said cylinder portion includes means for coupling to said grid having the coordinates of said microfiche thereon and wherein said traverse member includes a pointer member supported relative to said grid on said cylinder to identify the microimage on a microfiche at said optical axis.
Claim 5
Dependent Claim
22 words
The accessory of claim 1 including means for coupling to said indexer a plurality of microfiche in the form of microfilm strips.
Claim 6
Dependent Claim
19 words
The accessory of claim 1 further including means to identify the microimage on a microfiche adjacent the imaging station.
Claim 7
Dependent Claim
20 words
The accessory of claim 1 further including an envelope coupled to said transverse member for carrying and protecting a microfiche.
Claim 8
Dependent Claim
25 words
The accessory of claim 6 wherein said envelope includes upper and lower flaps of different lengths coupled at the same end to the transverse member.
Claim 9
Dependent Claim
43 words
The accessory of claim 6 wherein said envelope includes upper and lower flaps, one flap being anchored at one end to the traverse member leaving one end thereof free and the other flap being hinged to the free end of the anchored flap.
Claim 10
Dependent Claim
32 words
The accessory of claim 1 wherein said pivot member includes an arm portion journaled in the base and a slide portion extending generally perpendicular to the path traveled by the pivot member.
Claim 11
Dependent Claim
23 words
The accessory of claim 9 wherein said traverse member is coupled to the slide portion of the pivot member for sliding movement thereon.
Claim 12
Dependent Claim
251 words
An assessory to permit a viewer designed for reel film to be converted to a microfiche viewer, and back again, said viewer including a projection apparatus having a predetermined optical axis; spindles removably supporting supply and take up reels for said film on either side of said viewer optical axis whereby said film may be advanced across said optical axis for viewing thereof, the combination comprising a. a base member having spacer sockets for receiving said spindles whereby to enable said base member to be mounted in operative position on said viewer in place of said film reels, said base member having a cylinder portion adapted to support a grid in operative relation to said optical axis; b. a U-shaped pivot member rotatably mounted on said base member for arcuate movement over said cylinder portion of said base member about a predetermined axis substantially concentric with said cylinder portion, said pivot axis laying within the confines of said base member; and, c. A traverse means slidably mounted on the closed end of said pivot member so as to traverse across said grid and having a gripping means such that a microfiche held by said gripping means may be drawn across said optical axis for viewing thereof in a direction substantially traverse to said arcuate movement along a line parallel but spaced apart from said pivot member axis, said traverse means being movable independently of said pivot member movement, said gripping means comprising a transparent envelope for carrying and protecting said microfiche.
Claim 13
Dependent Claim
251 words
An assessory to permit a viewer designed for reel film to be converted to a microfiche viewer, and back again, said viewer including a projection apparatus having a predetermined optical axis; spindles removably supporting supply and take up reels for said film on either side of said viewer optical axis whereby said film may be advanced across said optical axis for viewing thereof, the combination comprising a. a base member having spacer sockets for receiving said spindles whereby to enable said base member to be mounted in operative position on said viewer in place of said film reels, said base member having a cylinder portion adapted to support a grid in operative relation to said optical axis; b. a U-shaped pivot member rotatably mounted on said base member for arcuate movement over said cylinder portion of said base member about a predetermined axis substantially concentric with said cylinder portion, said pivot axis laying within the confines of said base member; and, c. A traverse means slidably mounted on the closed end of said pivot member so as to traverse across said grid and having a gripping means such that a microfiche held by said gripping means may be drawn across said optical axis for viewing thereof in a direction substantially traverse to said arcuate movement along a line parallel but spaced apart from said pivot member axis, said traverse means being movable independently of said pivot member movement, said gripping means comprising a transparent envelope for carrying and protecting said microfiche.
Claim 14
Dependent Claim
36 words
The accessory of claim 11 further including a roof member coupled to said base which together with said cylinder portion defines a tunnel through which a microfiche is guided into and out of said optical axis.
