1. Field of the Invention
The present invention generally relates to imaging devices and, more particularly, to imaging devices that perform multi-item scanning during a single scanning operation.
2. Description of the Related Art
An imaging device, for example, a scanner, is typically used in a traditional mode where a lid of the imaging device is opened and a document, having images therein, is placed on a scan glass of the imaging device. The images of the document facing the scan glass are imaged/scanned by a scanning unit disposed within the imaging device. The scanned images may be printed on a print media as desired by a user or transmitted to an external device or host.
However, there are substantial limitations to imaging the document positioned on the scan glass of such imaging devices. One such limitation is that the user cannot actually see exactly how the document will be scanned as the images face the scan glass and there is a possibility that the user skews the document and does not know it until the imaging operation is performed. As a result, the user may receive final scanned images having an improper orientation with regard to the original document. This limitation becomes extremely significant when a plurality of documents, such as pictures, business cards, receipts, etc., is positioned on the scan glass. Thus, the user looses flexibility in scanning the plurality of documents in the traditional method.
Thus, there is a need to provide an imaging device that addresses at least some of the above problems yet providing a quality scanned image for the user.
Disclosed herein is an imaging device for imaging an original including an imaging unit disposed within a housing, an imaging surface disposed in an imaging relationship with the imaging unit within the housing, the imaging unit capturing an image of the original when positioned adjacent to the imaging surface, and a lid pivotably coupled to the housing for moving between a closed position and an open position The lid includes an inner surface for supporting the original disposed on the lid, and an original retaining member attached to the lid for selectively retaining the original against the inner surface. The retaining member maintains the original in a stable position relative to the inner surface of the lid such that there is little if any movement of the original when the lid is moved from the open to the closed position. When the lid is in the closed position, the original is positioned against the imaging surface for having its content captured by the imaging unit.
In some embodiments, the lid is pivotably coupled to the housing along an edge of the inner surface to rotate between the closed position and the open position. Further, the retaining member may be pivotably attached to the lid so that original may be placed and secured against the inner surface of the lid when the retaining member is pivoted in an open position, relative to the lid.
In some embodiments, the imaging surface is disposed in an inclined orientation, such as a substantially vertically orientation, within the housing such that the lid and the original retaining member are disposed in a non-horizontal position adjacent to the imaging surface when the lid is in the closed position.
In some embodiments, the original retaining member is detachably attached to the inner surface of the lid.

Further, as shown in
Imaging device 100 may include a print engine (not shown) for printing an image onto a sheet of media. The print engine may include various types of printing mechanisms including dye-sublimation, dot-matrix, ink jet or laser printing. For ease of description, the exemplary print engine may be an inkjet printing device although such description should not be considered limiting. The print engine may include a carriage having a position for placement of at least one print cartridge. According to the exemplary embodiment, two print cartridges may be utilized wherein, by way of example, a color cartridge is utilized for color printing and a black cartridge for text or other monochrome printing. As one skilled in the art will recognize, the color cartridge may include three inks, i.e., cyan, magenta and yellow inks. As an alternative, a single black cartridge may be used.
In another alternative embodiment, one or more printheads may be disposed in the carriage and one or more ink containers may be in fluid communication with the one or more printheads. In yet another alternative embodiment, at least one stationary printhead is disposed across a media path and at least one ink container may be in fluid communication with the at least one printhead.
Imaging device 100 may include one or more mechanisms (not shown) for picking a sheet of media from the media input tray, moving the picked sheet to be adjacent the print engine for printing an image thereon, and moving the picked sheet having the printed image to output area 105. During advancement, the picked media sheet moves from the input media tray to the media output area 105 along a substantially L-shaped media.

Alternatively, instead of utilizing a scan bar 140 for capturing an image of one or more originals P1-P3 a few scan lines at a time, imaging device 100 may capture substantially the entire image of the media sheet at one time. By capturing an entire image substantially simultaneously, scan bar 140 and its corresponding drive mechanism are not utilized. In this alternative embodiment, imaging device 100 may include light sources of sufficient number and placement to generate and direct light towards one or more originals P1-P3 disposed against imaging surface 136 so that light reflections may be captured by one or more image sensors.
As shown in
The lid 114 has an inner surface 146 and an outer surface 148 (shown in
Further, as shown in
When original retaining member 154 is in the closed position, the original retaining member 154 applies a slight pressure on the originals P1-P3 against the inner surface 146 of the lid 114 resulting in stably securing the originals P1-P3 against the inner surface 146 of the lid 114. For instance, a spring (not shown) may be coupled to original retaining member 154 and lid 114 so as to bias the unconnected end 160 of original retaining member 154 against lid 114. Alternatively the supporting portion 152 may be of backed by a foam material providing a spring surface so when retaining member 154 is in the closed position a slight pressure on the originals P1-P3 results. So, as the lid 114 moves between the open position and the closed position, the original retaining member 154 securely holds the originals P1-P3 against the inner surface 146 of the lid 114 during movement of the lid 114 between the two positions. Thus, a benefit of disposing the original retaining member 154 on the inner surface 146 of the lid 114 supporting the originals P1-P3 is that the originals P1-P3 remain intact in their respective positions and any misorientation of the originals P1-P3 caused due to movement of the lid 114 is avoided. Additionally, misorientation that may be caused by the gravitational forces acting on the originals P1-P3 when the lid 114 is disposed in the closed position is also avoided.
Furthermore, when the lid 114 is disposed in the closed position against the imaging surface 136 the originals P1-P3, which are disposed on the inner surface 146 of the lid 114 and slightly pressed by the original retaining member 154, is positioned adjacent to the imaging surface 136. Thus, the originals P1-P3 are not supported directly on the vertically oriented imaging surface 136 and there is not physical contact between the two. Rather, the originals P1-P3 are held by the original retaining member 154 against the inner surface 146 of the lid 114 and positioned adjacent to the imaging surface 136. Thereafter, upon proper selection of the selection buttons 112, the imaging unit 138 captures the images appearing on the originals P1-P3.
In the above embodiment of the imaging device 100 according to the present invention, the original retaining member 154 is attached by a hinged connection 158 to the inner surface 146 of the lid 114. However, there could be many ways to securely hold the originals P1-P3 against the inner surface 146 of the lid 114. In one embodiment of the imaging device 100 according to the present invention, the original retaining member 154 may be pivotably connected to the scan lid 114 along one side thereof and include a clasp or latch mechanism for securing an opposite side to the scan lid 114. Alternatively, original retaining member 154 may be held against lid 114 by a snap-fit engagement therewith. In another embodiment, the original retaining member 154 may be slidingly engaged with the lid 114 by sliding in an opening defined along the lid 114. Other mechanisms may also be utilized for detachably securing the original retaining member 154 to the lid 114 and be within the scope of the present invention.
Further, the original retaining member 154 may be made from a transparent or translucent material such as glass. However, the original retaining member 154 may be made from virtually any composition, such a plastic composition, so long as it is substantially transparent and/or allows for the imaging unit 138 to accurately capture an image of the originals P1-P3. Furthermore, the transparent material from which the original retaining member 154 is made may be flexible or may be made be rigid.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit and scope of the invention. Thus it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
