An optical code reading device.

摘要

Optical code reading device comprises a light source (3) for emitting reading light for illuminating an object (6) to be read, a lens system (5) disposed to receive the reading light and project the reading light towards the object, light detecting means (7) for receiving the light reflected from the object and generating an electric signal presenting the intensity of the reflected light, processing means (9) for processing the electric signal transferred for producing an electric signal representing the object and an additional light source (17) for generating visible light for sighting said reading light. Furthermore it is provided at least one optical fiber (4) for transferring the reading light from the light source (3) into the scanning head (1) and a plurality of additional optical fibers (19) for transferring the visible light from the additional light source (17) into the scanning head, the light emitting ends of the optical fiber (4) and the additional optical fibers (19) being positioned adjacent to each other.
