Patent ID: 7798736

Claim:
A media binder, comprising: a cover having a front, a back, and a spine, wherein the spine extends along a spine axis; at least one spring clamp attached to the spine and defining an interior cavity operable to receive physical media, wherein each spring clamp comprises opposing inner clamp surfaces that face the interior cavity and respectively define respective opposing clamping edges that are operable to move resiliently toward and away from on another between a closed state and an open state and apply a clamping force therebetween, and the at least one spring clamp is biased to resist movement of the clamping edges into the open state; at least one monolithic tension sheet, wherein each tension sheet is attached to the cover, extends from the cover, over at least one of the clamp edges, into the interior cavity, and over at least a portion of the respective inner clamp surface to which the tension sheet is attached, the at least one tension sheet being operable to transmit an opening force from the cover to the at least one spring clamp; and at least one datum stop each of which is coupled to the spine and disposed over the tension sheet such that the tension sheet is between the at least one spring clamp and the at least one datum stop, wherein each datum stop has a respective planar alignment surface in a plane that intersects and is orthogonal to the spine axis, wherein the alignment surface protrudes away from an inwardly facing side of the spine in a direction orthogonal to the spine axis and is exposed to engage at least one side edge of the physical media as the physical media is being inserted within the interior cavity.
