Abstract
Abstract An enclosure system includes a light-tight enclosure and a means for guiding the direction of movement of phototypesetting paper to and from the enclosure. The enclosure is capable of storing a roll of phototypesetting paper, of dispensing paper from said roll, and of returning paper onto said roll without folding or otherwise buckling the paper. The system obviates the need for a separate "take-up" enclosure and eliminates the problem of degraded print quality typically associated with characters printed at or near a fold. The enclosure comprises a container with a pivotally mounted spring-loaded lid with a gasket thereon, and a shaft disposed in the container for storing a roll of paper of selected width.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
137 words
Apparatus for dispensing and accumulating a driven web of selected rigidity and width without folding the web, the apparatus comprising: enclosure means having a chamber defined therein and a shaft disposed in the chamber for storing the web thereon, said enclosure means having an opening of selected width disposed along the length of said enclosure means sufficient to accommodate passage of the web therethrough; lid means pivotally affixed to the enclosure means and disposed over the opening and along the length of said enclosure means for preventing light from entering the enclosure means; and guide means disposed proximate to the enclosure means for guiding the driven web through said opening and under the lid means, enabling said web to be dispensed from the shaft and be accumulated in the chamber and about said shaft without becoming folded.
Claim 2
Dependent Claim
137 words
Apparatus for dispensing and accumulating a driven web of selected rigidity and width without folding the web, the apparatus comprising: enclosure means having a chamber defined therein and a shaft disposed in the chamber for storing the web thereon, said enclosure means having an opening of selected width disposed along the length of said enclosure means sufficient to accommodate passage of the web therethrough; lid means pivotally affixed to the enclosure means and disposed over the opening and along the length of said enclosure means for preventing light from entering the enclosure means; and guide means disposed proximate to the enclosure means for guiding the driven web through said opening and under the lid means, enabling said web to be dispensed from the shaft and be accumulated in the chamber and about said shaft without becoming folded.
Claim 3
Dependent Claim
41 words
The apparatus as in claim 1 wherein the enclosure means includes a first cap portion disposed at one end of the chamber, and a second cap portion removeably disposed at the other end of the chamber and attached to the shaft.
Claim 4
Dependent Claim
74 words
The apparatus as in claim 2 wherein the shaft is D-shaped, having a flat portion and having a rounded peripheral portion with grooves formed thereabout at selected locations, said shaft being disposed for supporting a pair of disc members, each disc member having a D-shaped central opening through which the shaft passes, each disc member being slideably mounted on said shaft for supporting the edges of a roll of paper inserted onto the shaft.
Claim 5
Dependent Claim
63 words
The apparatus as in claim 3 wherein each disc member includes a spring means forming a portion of the D-shaped central opening such that when the spring means encounters the flat portion of the shaft the dis member may be moved laterally along the shaft, and when the spring means encounters a groove in the shaft lateral movement of the disc is prevented.
Claim 6
Dependent Claim
46 words
The apparatus as in claim 4 wherein each disc member has a flat portion at its periphery, and the enclosure includes an elongated projected portion disposed within said enclosure for engaging the disc member at its rounded peripheral portion to prevent rotation of the disc member.
Claim 7
Dependent Claim
12 words
The apparatus as in claim 5 wherein the lid means is spring-loaded.
Claim 8
Dependent Claim
24 words
The apparatus as in claim 5 wherein the lid means includes a lid and a mechanical camming means for opening and closing the lid.
Claim 9
Dependent Claim
23 words
The apparatus as in claim 5 wherein the lid means includes a lid and a magnetic means for opening and closing the lid.
Claim 10
Dependent Claim
29 words
The apparatus as in claim 5 wherein the lid means includes a lid which may be opened by the force of gravity and closed by a mechanical latching means.
Claim 11
Dependent Claim
14 words
The apparatus as in claim 7 wherein the mechanical camming means is a wedge.
Claim 12
Dependent Claim
13 words
The apparatus as in claim 8 wherein the magnetic means is a solenoid.
Claim 13
Dependent Claim
17 words
The apparatus as in claim 8 wherein the magnetic means is a pair of magentically opposed magnets.
Claim 14
Dependent Claim
15 words
The apparatus as in claim 9 wherein the mechanical latching means is a slide pin.
