Abstract
Abstract A microfiche carrier is provided comprising a carrier of transparent sheet material having a strip of pressure sensitive adhesive thereon for securing a microfiche to one face of the carrier. The microfiche carrier is adapted to be stacked with other microfiche carriers to form a deck, and the deck is placed into a magazine from which selected microfiche may be partially withdrawn for viewing a particular frame or frames of the microfiche. The microfiche carrier also includes detent means for releasably retaining the microfiche carrier in the magazine, coding means for retrieval of a selected microfiche carrier from the magazine and ramp means to prevent edge interference with adjacent carriers and microfiche in the magazine when a selected microfiche carrier is retrieved from or returned to the magazine.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
119 words
A microfiche carrier, comprising: a sheet of flexible transparent material having a first and a second surface defining a carrier; a plurality of ramp means on the first surface of the carrier to prevent edge interference with adjacent carriers in response to retrieval of a selected microfiche carrier from a deck of microfiche carriers in a suitable magazine, each said ramp means extending at an incline from a front edge of the ramp means flush with the first surface to a rear edge of the ramp means raised above the first surface; and a strip of adhesive means on the first surface adjacent to the rear edges of the ramp means and parallel thereto for securing a microfiche thereto.
Claim 2
Dependent Claim
119 words
A microfiche carrier, comprising: a sheet of flexible transparent material having a first and a second surface defining a carrier; a plurality of ramp means on the first surface of the carrier to prevent edge interference with adjacent carriers in response to retrieval of a selected microfiche carrier from a deck of microfiche carriers in a suitable magazine, each said ramp means extending at an incline from a front edge of the ramp means flush with the first surface to a rear edge of the ramp means raised above the first surface; and a strip of adhesive means on the first surface adjacent to the rear edges of the ramp means and parallel thereto for securing a microfiche thereto.
Claim 3
Dependent Claim
27 words
A microfiche carrier as set forth in claim 1 further comprising a coding tab having a formed surface therein positioned on a front edge of the carrier.
Claim 4
Dependent Claim
29 words
A microfiche carrier as set forth in claim 1 further comprising a releasable protective means covering the adhesive means adapted to be removed prior to securing a microfiche thereto.
Claim 5
Dependent Claim
29 words
A microfiche carrier as set forth in claim 1 further comprising a detent means including a flexible leg on the carrier for releasably holding the carrier in the magazine.
Claim 6
Dependent Claim
39 words
A microfiche carrier as set forth in claim 4 in which the detent means comprises a pair of flexible legs positioned at front corners of the carrier, each said flexible leg having a detent concavity in one edge thereof.
Claim 7
Dependent Claim
43 words
A microfiche carrier as set forth in claim 5 in which the flexible legs are formed by a key-hold slot configuration for providing sufficient flexibility to the legs to permit another type of detent means on the magazine to engage the detent concavity.
Claim 8
Dependent Claim
17 words
A microfiche carrier as set forth in claim 1 in which the carrier comprises a polyester film.
Claim 9
Dependent Claim
188 words
A microfiche carrier, comprising: a sheet of flexible transparent material having a first and a second surface defining a carrier; a plurality of ramp means on the first surface of the carrier to prevent edge interference with adjacent carriers in response to return of a selected carrier to a deck of carriers in a suitable magazine, each said ramp means extending at an inclined from a front edge of the ramp means flush with the first surface to a rear edge of the ramp raised above the first surface; a strip of pressure sensitive adhesive provided on the first surface adjacent to the rear edges of the ramp means and parallel thereto; coding means provided with a formed surface therein positioned on a front edge of the carrier; and detent means comprising a pair of flexible legs positioned at front corners of the carrier, each said flexible leg having a detent concavity in one edge, said flexible legs being formed by a key-hole slot configuration for providing sufficient flexibility to the legs to permit another type of detent means on the magazine to matingly engage the detent concavity.
Claim 10
Dependent Claim
188 words
A microfiche carrier, comprising: a sheet of flexible transparent material having a first and a second surface defining a carrier; a plurality of ramp means on the first surface of the carrier to prevent edge interference with adjacent carriers in response to return of a selected carrier to a deck of carriers in a suitable magazine, each said ramp means extending at an inclined from a front edge of the ramp means flush with the first surface to a rear edge of the ramp raised above the first surface; a strip of pressure sensitive adhesive provided on the first surface adjacent to the rear edges of the ramp means and parallel thereto; coding means provided with a formed surface therein positioned on a front edge of the carrier; and detent means comprising a pair of flexible legs positioned at front corners of the carrier, each said flexible leg having a detent concavity in one edge, said flexible legs being formed by a key-hole slot configuration for providing sufficient flexibility to the legs to permit another type of detent means on the magazine to matingly engage the detent concavity.
