Patent Application
20140022606
1. Technical Field
The present disclosure relates to an image forming apparatus, and particularly to a scanning apparatus for large scale documents.
2. Description of Related Art
Generally, a scanner is used to scan documents to form images of the documents. For different sized documents, there exists a need for different kinds of scanners. For example, an A4 size scanner cannot scan an A3 size document because the scale of the scanner is smaller than the scale of the document.
Therefore, there is room for improvement within the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
The control module 60 connects to the scanning sensor 30, and an image processing module 70.
The main body 20 includes a top side 25. The top side 25 includes a transparent document placing portion 21. The document placing portion 21 can be rectangular which includes a pair of long edges 211 and a pair of short edges 212. The scanning sensor 30 is located below the document placing portion 21. A length of the scanning sensor 30 is generally equal to or slightly smaller than half of the short edge 212. A document can be placed on the document placing portion 21 and scanned by the scanning sensor 30. The main body 20 includes a first end 201 and a second end 202.
The scanning sensor 30 slides below the document placing portion 21. The scanning sensor 30 can be aligned to the short edge 212 of the document placing portion 21 and can slide along the long edge 211 and the short edge 212.
Referring to
At an initiatory position, the scanning sensor 30 is located below the first portion 81 and adjacent the first end 201 to be located at a first position. To scan the document 80, the scanning sensor 30 slides along the long edge 211 from the first end 201 to the second end 202 and below the transparent document placing portion 21 to slide the first portion 81 to get a first image file 91 corresponding to the first portion 81. The scanning sensor 30 is now in a second position. Then, the scanning sensor 30 slides along the short edge 212 to be located below the second portion 82 to be located at a third position. The scanning sensor 20 slides below the second portion 82 from the second end 202 back to the first end 201 to be located at a fourth position. In succession, the scanning sensor 20 moves from the fourth position to the third position to scan the second portion 82 to obtain a second image file 92 corresponding to the second portion 82. The scanning sensor 30 then moves back to the first position to reposition. At last, the image processing module 70 combines the first image file 91 and the second image file to generate a combined image file 93 corresponding to the document 80.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
