Patent ID: 7595990

Claim:
A scanning apparatus with heat dissipating ability, for scanning a document, comprising: a housing, having an opening formed on a top surface of the housing, and having a containing space defined therein; a cover, fixed on the top surface of the housing for covering the opening, and having a slit, a heat dissipating portion, and a supporting portion connected to the heat dissipating portion, wherein the supporting portion extends from an edge of the slit into the containing space of the housing; a light emitting unit, comprising; a substrate, fixed on the supporting portion wherein a plurality of first positioning parts is formed on an edge of the substrate, a plurality of second positioning parts corresponding to the first positioning parts is formed on the supporting portion of the cover, and the first positioning parts and the second positioning parts are engaged with each other, so as to position the substrate on the supporting portion; a plurality of light emitting elements, disposed on the substrate, for emitting a scanning light to the document through the slit, such that the scanning light is reflected to form an image light, wherein the heat generated by the light emitting elements is transferred to the heat dissipating portion through the substrate and the supporting portion; and an image scanning module, disposed in the containing space, for receiving and converting the image light to an image data.
