ABSTRACT:
An optical reading device has projection optics which have an optical axis and focus light emitted by a light source present in a reading head, and having light receiving optics, arranged horizontally with respect to the optical axis, for receiving light focused by the projection optics and reflected back from an object. The light source can be displaced along the optical axis, relative to the projection optics, in order, during the scanning of pattern originals, to be able to change the size of the scanning light point in accordance with the original structure, without a displacement of the light receiving optics being necessary.
