ABSTRACT:
The present invention relates to a multiple-resolution image scanning apparatus, comprising: a main body with at least one carrier for accommodating an object of one of several data types to be scanned; and a scanning system, installed in the main body and movable parallel to the carrier. The scanning system further comprises: a detector; a light source for illuminating the object; at least two imaging systems with lenses and mirror groups, which alternatively generate an image of an object on the detector at different resolutions and with different light paths; and a switching system, which moves the imaging systems and the detector relative to each other into reading positions, wherein in each of the reading positions the image is generated on the detector by one of the imaging systems. This allows to scan objects of different data types.
