Claim 0:
1. A strip cutting apparatus for a diagnostic reagent kit which cuts a plate-shaped diagnostic reagent into several band strips in a width direction at a time, the strip cutting apparatus comprising:
a frame;
a first shaft having a disc shape, including a plurality of spacers and a plurality of knives comprising blades, which contact each other and face each other, and an adjusting nut coupled and fastened to at least one side thereof so that the knives and the spacers are secured to the first shaft, the spacers and the knives being fixed in such a way that two knives and one spacer are fit onto the first shaft alternately not to rotate;
a second shaft having a disc shape, including a plurality of spacers and a plurality of knives comprising blades, which contact each other and face each other, and an adjusting nut coupled and fastened to at least one side thereof so that the knives and the spacers are secured to the second shaft, the spacers and the knives being fixed in such a way that two knives and one spacer are fit onto the second shaft alternately not to rotate; and
a guide member, which includes a first guide mounted on the spacer of the first shaft and a second guide mounted on the spacer of the second shaft, the guide member supporting a diagnostic reagent so that the diagnostic reagent is cut when the diagnostic reagent goes between the first shaft and the second shaft,
wherein the knives are mounted to rotate on the frame to cut the diagnostic reagent into several strips by shearing force when the first shaft and the second shaft rotate on the frame at the same time, and
wherein at least two concentricity adjusting screws are coupled to the adjusting nuts of the first shaft and the second shaft in a threaded type in order to adjust concentricity of the knives and the spacers by changing a rotation amount of the adjusting screws into a straight line to push the knives and the spacers in a width direction.
