Description:
BACKGROUND 
     Scanners are generally handheld, sheet-fed or flatbed. Handheld scanners are held by a user and passed over a document or photograph to digitally scan its image. The image quality of a scan performed with a handheld scanner is largely dependent on the steadiness and alignment of the scan pass. Sheet-fed scanners are generally integrated into another device, such as a fax machine; scanning for output to a personal computer or similar device is a secondary function. The quality of images associated with a sheet-fed scanner is largely dependent on the ability of the feed mechanism to handle the article being scanned. 
     As relatively high resolution flatbed scanners have grown in popularity, handheld scanners have become largely obsolete, while sheet-fed scanners are relegated to the aforementioned secondary role. Flatbed scanners are configured similar to a copier. A document cover lid is opened, the item or media to be scanned is placed face down on a platen or document glass, and a mechanism disposed beneath the glass is activated to scan a digital image of the media. Typically the document cover is closed over the document or photo to hold the media in place and to shut out ambient light. Use of a flatbed scanner is generally not intuitive. Alignment and proper positioning of a photograph, document or other media to be scanned may be problematic to the computer neophile. 
     Necessarily, a flatbed scanner has a large “footprint” as it must accommodate a document or similar media laid flat. Although smaller flatbed scanners have been introduced, these scanners are generally sized to accept four inch by six inch, or smaller, photographs or similar media. This smaller type of scanner is particularly well suited for sending or sharing photographs with friends and family, via email. Therefore, these small format scanners are generally intended for non-computer users and are often adapted to facilitate attachment of a scanned image to an email using a television set top box such as a WebTV® device. These small format scanners generally use contact image sensor (CIS) technology. 
     Computer software, email and Internet traffic have become image intensive. Therefore, the use of scanners has become more prevalent. As broader use of scanner technology has developed, several barriers have arisen.

     DETAILED DESCRIPTION 
     Turning now to the FIGURES, the present invention is directed to flatbed envelope scanner  100  particularly well adapted for sharing photographs with family and friends by nontechnical, casual users. Scanner  100  provides a comfortable, intuitive interface familiar from everyday experience, namely an envelope. To communicate the functionality of sharing photographs or other type of media by electronically mailing them to someone else, present scanner  100  (hereafter referred to as “envelope scanner  100 ”) takes the form of the back of an envelope. Envelope scanner  100  eases use and alignment issues present with existing scanners by providing intuitive guidance for its functional use, which is easily recognizable by the casual, nontechnical user. Hence, one opens flap  101  of envelope scanner  100  and inserts a letter, a photograph or similar planar media into slot  501  of envelope scanner  100 , and closes flap  101  of envelope scanner  100 . The user then presses send button  102  to send an electronic image of the media as an attachment to email to another party or parties. 
     As will be appreciated by one skilled in the art, the improvements for a scanner disclosed herein may be advantageously incorporated into an oversized scanner or a conventional size scanner, as well as the aforementioned smaller footprint scanner useful for scanning photographs or similar smaller media. The present invention provides a convenient way to insert media for scanning, without limiting versatility of a scanner embodying the present invention. A scanner embodying the present invention may still scan in a conventional manner employing document cover  105  or with document cover  105  removed. A conventional size scanner embodying the present invention may receive conventional size media, such as letter, legal or A4 size documents, into slot  501  as well as smaller media such as photographs. A smaller photo oriented scanner embodying the present invention may receive photos or smaller media through slot  501  for scanning. 
     As shown in  FIGS. 1 through 4 , envelope scanner  100  preferably takes an envelope form in size and appearance. Envelope scanner  100  is preferably a small, thin flatbed scanner having a generally parallelepiped housing  103 . The housing is adapted to rest on a supporting surface such as a tabletop, desktop, other furniture, cabinet, countertop, floor, etcetera. The housing is further adapted to support a document glass or platen  201 . Platen  201  is supported by the generally planar upper side  202  of housing  103 . Platen  201  is adapted to abut, face down, a photograph or similar media such as, but not limited to a sheet of paper, document, letter, other writing, clipping, drawing, planar artwork, or the like. Preferably the user employs send button  102  to initiate operation of a contact image sensor (CIS) or other scanning mechanism, operatively disposed within the housing. The CIS moves under the glass and digitally scans an electronic image of the media placed on the platen. A preferred embodiment of the envelope scanner has a generally low profile facilitated by the use of CIS technology. 
     With attention directed to  FIGS. 2 and 4  through  6 , preferably, document cover  105  is hinged to housing  103  to cover platen  201  during scanning operations and provide a minimum footprint when not in use. Preferred document cover  105  comprises two portions, a generally rectangular cover base  106  hinged, via one or more hinges  602 , to scanner housing  103  and a triangular envelope flap  101 . Preferably, envelope flap  101  is hinged to cover base  106  via one or more hinges  110 . As detailed below, flap  101  is useful for scanning photographs or other planar media. For other types of media such as magazines, books, oversized documents or oversize photographs, entire document cover  105  hinges and lays flat relative to platen  201 . Alternatively, entire document cover  105  may be removed to facilitate scanning of large and/or irregularly shaped items. 
     As best seen in  FIG. 5 , when triangular envelope flap portion  101  of document cover  105  is flipped open, media receptive slot  501  is revealed between cover base  106  and platen  201 . Thus open, the flap also reveals generally triangular opening  206 , best seen in  FIGS. 2 ,  4  and  6 , defined by flap  101  and cover base  106 . Guides  502 , best seen in  FIGS. 5 and 6 , under document cover  105  facilitate more precise, automatic locating of the photograph or other planar media to be scanned allowing the user to insert the media through slot  501  and slide it into position more easily. The edges of the media slide along one or both guides  502  and the media comes to rest against stop  601 , similar to sliding a document into an envelope. Guides  502  and stop  601  automatically locate the media in the correct position on platen  201  for scanning. Preferably, flap  101  and document cover base  106  employ snap closure projection  204  and snap enclosure indent  205  to snap fittingly secure flap  101  to document cover base  106  to facilitate use of the document cover  105  as a unit. 
     As seen in  FIGS. 2 and 4 , face down icon  203  reminds a user to insert media into slot  501  face down for scanning. Preferably, icon  203 , or alternatively a second icon, indicates top and bottom of the media. As illustrated in  FIG. 6 , directional icons  603  and  604  disposed about the periphery of platen  201  on upper side  202  of housing  103  facilitate proper orientation of the media to be scanned when document cover  105  is opened to scan oversized items. 
     Returning to  FIG. 1 , an input/output port  108 , such as a universal serial bus (USB) connector is preferably disposed on a side of the housing  101  for connecting envelope scanner  100  to a PC, set top box or similar processing device. Preferably, port  108  offers both I/O capability and power to envelope scanner  100 . Alternatively, power input port  109  receives a power supply cord from a transformer or similar power source. 
     To use the envelope scanner, the user preferably opens flap  101  and slips the media to be scanned inside envelope scanner  100 , through slot  501 , face down, snaps flap  101  closed and presses send button  102 . As will be appreciated by one skilled in the art, flap  101  need not necessarily be snapped closed, but may rather rest closed in place during scanning. Depending on the software employed by the attached computer, set top box or other processing device and its set-up, a digital image of the media is immediately sent to a predetermined recipient, or a software program is called up on the PC or similar device where the user enters the destination and adds any desired text. 
     Preferably, the envelope scanner also offers a rotate button  107 . If the orientation of the media or photograph is portrait rather than landscape, the rotate button preferably allows a user to rotate the scanned image ninety degrees, so that the image will appear on the receiver&#39;s computer screen or television in the proper orientation. If the image is not in the correct orientation following use of the rotate button, then the user can continue to click the rotate control button, multiple times, until the image is in the correct orientation.
