ABSTRACT:
A device for the optical identification of a bar coding on a diagnostic test strip in an evaluation device in which the test strip is positively movable relative to a reading device for the coding, with a source of light as a transmitter and a light-sensitive element as a receiver. The bar coding has a high information density and between the test strip and the transmitter and/or between the test strip and the receiver there is, in each case, present a slit aperture and a cylindrical lens. The lens axis runs parallel to the test strip surface carrying the coding and to the code bars, the slit aperture lies in the plane defined by the cylinder axis and the transmitter or receiver and the distance between the lens axis and the test strip surface is substantially such that the focus lines of the lens lie approximately in the test strip surface.
