AI Technical Summary

Benefits of technology

Enables precise and uninterrupted scanning with direct observation of the scanning module's position, efficient use of space, and the capability to scan reflective and transparent documents with improved user convenience and flexibility.

Problems solved by technology

However, the performance bar 24 is unable to precisely indicate the position of the scanning module 20 because it takes time to process mass digital signals.
In this regard, it is inconvenient.
Moreover, this kind of action of a user would interfere in the scanning processes.
Further, since the flatbed scanner requires a lot of area to be placed, it is therefore not efficient to use the flatbed scanner in a restricted office environment.

Embodiment Construction

[0014]Please refer to FIGS. 2 and 3. FIG. 2 shows the scanning device 30. FIG. 3 shows the rear view of the scanning device 30. The scanning device 20 is able to stand on the table or to be placed flat on the table. The scanning device 30 comprises a document plate which can be a transparent plate 32, two sliding guides 36 and a scanning module 38, wherein the scanning module 38 is placed in front of the transparent plate 32. The two sliding guides 36 are adjacent to the transparent plate 32 in each side in parallel. The scanning module 38 is a contact image sensor (CIS). The scanning device 30 further comprises a first light source 40 which is assembled inside the scanning module 38 to provide light for scanning reflective documents, a second light source 46 placed in the rear side of the transparent plate 32 to provide light for scanning transparent documents, a driving module 42 electrically connected to the scanning module 38 for driving the scanning module 38 to scan the docume...
