ABSTRACT:
In the apparatus for feeding test strips automatically into an analyzer, in order to separate these, fix the position of the test zones and reverse the test strips and moisten their test zones with liquid, a supply container (1) for the test strips (13) is equipped with an orifice (14), in which a transport device (12) is arranged. The transport device is equipped with a guide plate (7) and with drivers and has noses (19, 19a) which interact with a moveably arranged bar (11) projecting into the orifice (14). The guide plate (7) merges into a guide (8) which opens into a reversing device (2, 2a). Between guide (8) and reversing device is arranged a closing means (9) for the guide (8), the said closing means being connected via a lever (5) to a holding device (10) for the test strips (13), and the holding device projects into the guide and is mounted rotatably in synchronism with the closing means. It is also equipped with a drive device (16). The reversing device (2, 2a) has a moveable stop (4, 4a) which is driven by a position-detection means (6) arranged in the guide. The reversing device is followed by a conveyor belt (27), above which a spray device (28) is arranged so to be displaceable parallel to the test strip. The spray device is equipped with a sensor (45) which stops the conveyor belt (27) when the test strip is located under the spray device.
