Abstract
A scanner including at least a casing, a scanning platform, a carriage and a lateral reversing device is provided. The scanning platform is installed on the covering panel of the casing and is used to accommodate at least one document. The carriage is movably installed in the casing and will transmit a scan-finished signal after having scanned the front side of a document. The lateral reversing device, which is installed at a lateral side of the scanning platform, is equipped with a control unit and is used to turn the document over for the reverse side of the document to be scanned after the control unit has received the scan-finished signal.
Claims23
A system, comprising:
- a scanning platform to accommodate at least one document;
- a carriage to scan a first side of the document on the scanning platform;
- and
- a lateral reversing device to retrieve the document from the scanning platform, to feed the document through a gyration path having a contour that overturns the document, and to provide the overturned document back to the scanning platform for the carriage to scan a second side of the document, wherein the carriage is configured to generate a scan-finished signal that indicates the scan of the first side of the document is complete, and wherein the lateral reversing device includes at least one roller that rotates in a first direction in response to the scan-finished signal to feed the document through at least a portion of the gyration path.
1 more element
A scanner, comprising:
- a scanning platform to accommodate at least one document;
- a carriage to scan a first side of the document on the scanning platform;
- a lateral reversing device having a first roller that rotates when coupled to a drive gear, wherein:
- when rotating in a first direction, the first roller is configured to retrieve the document from the scanning platform and feed the document through a gyration path having a contour that overturns the document;
- and
- when rotating in a second direction, the first roller is configured to provide the document back to the scanning platform for the carriage to scan a second side of the document.
3 more elements
A method comprising:
- scanning a first side of a document on a scanning platform;
- retrieving the document from the scanning platform;
- feeding the document through a gyration path having a contour that overturns the document after the scanning of the first side of the document;
- returning the overturned document to the scanning platform for scanning of a second side of the document;
- and
- selectively coupling a drive gear rotating in a first direction to a first roller in response to a scan-finished signal, wherein the first roller retrieves the document from the scanning platform and feeds the document through the gyration path to overturn the document.

The A system comprising:
- a scanning platform to accommodate at least one document;
- a carriage to scan a first side of the document on the scanning platform;
- and
- a lateral reversing device to retrieve the document from the scanning platform, to feed the document through a gyration path having a contour that overturns the document, and to provide the overturned document back to the scanning platform for the carriage to scan a second side of the document, wherein the lateral reversing device comprises:
- a drive gear configured to rotate in a first direction in response to a scan-finished signal that indicates the scan of the first side of the document is complete and configured to rotate in a second direction in response to an interrupt signal that indicates the document is in the gyration path;
- and
- a first roller configured to couple to the drive gear in response to the scan-finished signal and configured to retrieve the document from the scanning platform by rotating in the first direction.
4 more elements
A system, comprising:
- means for scanning a first side of a document on a scanning platform;
- means for retrieving the document from the scanning platform and feeding the document through a gyration path having a contour that overturns the document;
- means for selectively coupling a drive gear rotating in a first direction to the means for retrieving in response to a scan-finished signal that indicates the first side of the document has been scanned, wherein the means for retrieving retrieves the document from the scanning platform based, at least in part, on the selective coupling to the drive gear;
- and
- means for returning the overturned document to the scanning platform for scanning of a second side of the document.
