first embodiment
[0022]Referring now to FIG. 2, the light source mechanism for an imaging apparatus in accordance with the present invention is shown explodedly.
[0023]The light source mechanism 2 as shown includes a single point light source 21 and a light shield 22. The point light source 21 can be a light emitting diode (LED) which has advantages of low cost, longer life term, stable illumination and a wider wave range for application. To meet the requirement of the line light source for scanning the document, the light source mechanism 2 of the present invention utilizes the light shield 22 to transform the lights of the point light source 21 into an applicable line lights.
[0024]As shown in FIG. 2, the light shield 22 of the present invention, shaped as a long hollow pipe structure, includes an upper half 221 and a mating lower half 222. The light shield 22 can be preferably made of opaque materials. One end of the light shield 22 includes a mounting element 223 for installing the point light sou...
second embodiment
[0029]Referring now to FIG. 4, the light source mechanism for an imaging apparatus in accordance with the present invention is shown explodedly.
[0030]In the second embodiment, the light source mechanism 2a can include two point light source 21a and 21b, and a light shield 22a. The point light source 21a or 21b can be a light emitting diode (LED) which, as said in previous description, has advantages of low cost, longer life term, stable illumination and a wider wave range for application. These two point light sources 21a and 21b are preferably mounted to opposing ends of the light shield 22a.
[0031]As shown in FIG. 4, the light shield 22a of the present invention, shaped as a long hollow pipe structure, includes an upper half 221a and a mating lower half 222a. The light shield 22a can be preferably made of opaque materials. Each of both ends of the light shield 22a can include a respective mounting element 223a or 223b for installing the respective point light source 21a or 21b. One...
