ABSTRACT:
A image reading device is activated by the light interference of a light path. The image reading device comprises at least a image sensing element, a picture and a image changing mechanism such as a picture conveying module, picture rotating module, a hole or a soft button with picture in the inner side. The user may use finger or other objects to interfere the image generated in the image sensing element. By detecting the changes of the image, a predetermined activation process of the image reading device is therefore started.
