Abstract
A scanning apparatus for scanning a bound document includes a scanning flatbed, a lighting device, and a scanning head assembly. The scanning flatbed includes a platen and an inclined plane, wherein the platen is adjoined with the inclined plane, and the platen supports a document to be scanned. The lighting device, facing the scanning flatbed, projects light onto the document, wherein the lighting device includes a first portion and a second portion, and the first portion and the second portion respectively comprise a plurality of LEDs arranged in an array. The scanning head assembly, coupled to the lighting device, scans the document. The first portion is located closer to the inclined plane than the second portion, and intervals between the LEDs of the first portion are smaller than intervals between the LEDs of the second portion.
