Abstract
A vertically oriented image scanning device includes a chassis with a vertically oriented scanning window and a flap cover pivoted to the chassis. A document support flange is formed along a lower edge of the scanning window for aligning a document with respect to the scanning window. A thin metal plate has opposite edges attached to an inner face of the flap cover and forms a convex configuration for elastic deformation and thus applies a force to retain the document against the scanning window. The convex configuration also helps guide the document into position. Alternatively, a resilient pad replaces the thin metal plate for applying a force to the document.
Claims20
An image scanning device, comprising:
- a chassis comprising a vertical scanning window;
- a scanner cover movably attached to said chassis and comprising an inner face, wherein said scanner cover is configured to movably cover said vertical scanning window;
- a document retainer attached to said inner face of said scanner cover, wherein said document retainer comprises a resilient member configured to resiliently force said document against said vertical scanning window if said scanner cover is closed;
- a document support flange formed along a lower edge of said vertical scanning window;
- and
- a pair of projections formed on opposite ends of said document support flange, wherein said document support flange or said pair of projections are configured to substantially align said document with said vertical scanning window.
An image scanning device, comprising:
- a chassis including a vertical scanning window;
- a flap cover movably attached to the chassis and comprising an inner face, wherein said flap cover is configured to movably close toward said vertical scanning window;
- and
- a document retainer attached to said inner face of said flap cover, wherein said document retainer comprises a plurality of bow-shaped resilient strips each having at least one end attached to the inner face of said flap cover, and wherein said document retainer is configured to resiliently force said document against said vertical scanning window if said flap cover is closed.
An image scanning device, comprising:
- a chassis comprising a vertical scanning window;
- a scanner cover movably attached to said chassis and comprising an inner face, wherein said scanner cover is configured to movably cover said vertical scanning window;
- and
- a document retainer attached to said inner face of said scanner cover, wherein said document retainer is configured to resiliently force said document against said vertical scanning window if said scanner cover is closed, and wherein said document retainer comprises a plurality of bow-shaped resilient strips.
A method of using an image scanning device for scanning a document, comprising:
- placing a document to be scanned between a vertically oriented image scanning window and a movable cover having a plurality of bow-shaped resilient members;
- and
- forcing said plurality of bow-shaped resilient members to deform by closing said movable cover, wherein said plurality of bow-shaped resilient members are configured to press;
- said document against said image scanning window.
An image scanning device for scanning a document, comprising:
- a vertical image scanning window;
- a cover for said scanning window;
- a bow-shaped document retainer configured to press a document against said image scanning window;
- and
- a guide configured to guide a document into alignment relative to said vertical image scanning window, wherein said guide forms a lip below said vertical window and includes upward protrusions configured to horizontally align said document relative to said image scanning window.
An apparatus, comprising:
- means for supporting an image scanning window in a vertical orientation;
- means for moveably covering said image scanning window;
- and
- means for holding a document against said image scanning window using a plurality of bow-shaped resilient members, wherein said document is pushed against said image scanning window when said means for covering said image scanning window is closed.
