摘要： The present invention is configured such that a guide bar for supporting a diagnostic reagent paper includes a groove and the groove prevents the diagnostic reagent paper from being supported by a guide member in a section where knives using a shear force cut the diagnostic reagent paper, whereby a pressed line generated when the guide member presses the diagnostic reagent paper due to a cutting force by the knives is prevented from being formed on a strip so as to eliminate defects of the strip. In particular, the present invention is configured such that the guide member is installed to be disposed to pass through a space between a first shaft and a second shaft, each formed by repeatedly arranging two knives facing each other and one space, so as to guide the diagnostic reagent paper, whereby a section through which the diagnostic reagent paper passes has a substantially rectangular shape. Therefore, not only can the diagnostic reagent paper cut into strips accurately by a blade, but also the cut strips have no defects such as bending, entangling, or twisting.

摘要： The present invention is configured such that an adjustment nut for fixing spacers and blades repeatedly fitted to a shaft is provided with at least two concentricity adjustment screws, and, with the spacers and the blades fixed by the adjustment nut, the spacers and the blades are pushed by the concentricity adjustment screws in the direction of the shaft to enable concentricity adjustment, and thus, without causing defects, the blades are protected and can be used for a long time. In particular, according to the present invention, while one side shaft with respect to a diagnostic sheet is elastically supported, position adjustment in the longitudinal direction thereof is possible, and also projections are formed on the peripheries of the surfaces of the spacers facing the cutting edges of the blades thus to provide extra spaces for the blades in which the blades move, thereby preventing the deformation of cut strips and the damages on the blades.
