Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
239 words
A device for storing flat recording media comprising: a housing having a top wall, side walls, a rear wall and an open front; at least one plate member disposed in said housing opposite said top wall, said plate member cooperating with said housing walls to define at least one compartment in said housing, said plate member including guide rails positioned in said compartment; a slider member in each said compartment, each said slider member having a bottom which defines a recording media support surface, said slider members cooperating with plate member guide rails whereby said slider members are moveable through said housing open front between an inserted position where a recording media supported on said support surface is located in a said compartment and an ejected position in which recording media can easily be removed from the slider member; a spring in each said compartment for biasing the slider member in the compartment toward its ejected position, each said spring assuming an extended configuration when its associated slider member is in the inserted position, a tensioned bias-producing portion of each said spring being positioned between a said support surface and a said plate member when in said extended configuration, said spring members pulling said slider members from the inserted toward the ejected position of the slider members; and manually releasable locking means for holding each slider member in its inserted position against the bias of an associated said spring.
Claim 2
Independent Claim
239 words
A device for storing flat recording media comprising: a housing having a top wall, side walls, a rear wall and an open front; at least one plate member disposed in said housing opposite said top wall, said plate member cooperating with said housing walls to define at least one compartment in said housing, said plate member including guide rails positioned in said compartment; a slider member in each said compartment, each said slider member having a bottom which defines a recording media support surface, said slider members cooperating with plate member guide rails whereby said slider members are moveable through said housing open front between an inserted position where a recording media supported on said support surface is located in a said compartment and an ejected position in which recording media can easily be removed from the slider member; a spring in each said compartment for biasing the slider member in the compartment toward its ejected position, each said spring assuming an extended configuration when its associated slider member is in the inserted position, a tensioned bias-producing portion of each said spring being positioned between a said support surface and a said plate member when in said extended configuration, said spring members pulling said slider members from the inserted toward the ejected position of the slider members; and manually releasable locking means for holding each slider member in its inserted position against the bias of an associated said spring.
Claim 3
Dependent Claim
