Abstract

A test strip evaluating instrument is used for testing of multiple test strips, and has a transport and positioning device which transports the test strips at right angles to their longitudinal direction from a test strip feed area along a transport path to a disposal area. At least one measuring station with an optical measuring unit is arranged on the transport path. Rails, on which the test strips slide, run along the transport path. The test strips are transported in a step-wise manner by at least two rows of cam elements following one another in the transport direction, and these two rows of cam elements move synchronously with one another in a periodically recurring movement path. The handling of the test strips is facilitated without impairment of the measuring accuracy by the fact that the rails are longitudinally aligned as thin ribs in a disposable transport insert made of a thin plastic material, in which the cam elements engage from above between adjacent pairs of the rails of the transport insert, and in which a bearing element is provided for the tranport insert which supports the transport insert with a support surface in a central area lying between the test strip f…
