Abstract:
An image reading apparatus for reading an image on a transparency, said image reading apparatus comprising:a plate for supporting the transparency; a lighting module, disposed at one side of said plate, comprising a light source for emitting light to the transparency and an electromagnet disposed on said lighting module, said electromagnet adapted to be selectively activated; a scanning module, disposed at the other side of said plate, comprising an image sensor for receiving the light passing through the transparency, and converting the light to corresponding electric signals representing the image on the transparency; wherein when said image reading apparatus is operated to read the transparency said electromagnet is activated to generate magnetism and said lighting module is attracted to said scanning module by said magnetism and moves along a scanning path synchronously with said scanning module, and when said image reading apparatus is not operated to read the transparency, said electromagnet is not activated.
