摘要： In an electronic balance with a scale on top with two guide rods which connect a load receiver to a system carrier fixed to the housing as parallel guide, with at least one translation lever which is connected to the system carrier by means of two springs and with a coupling element (9) which transfers the force corresponding to the mass of the weighed material from the load receiver to the shorter lever arm of the translation lever while the counteracting force imposes on the longer lever arm of the translation lever. The two springs and the coupling element (9) are connected to each other by a common cross piece (8) and consist of a single sheet of metal, whereby the thickness of the sheet of metal is greater than the shorter lever arm of the translation lever and the material thickness is reduced in such a manner both in the area of the two springs and in the area of the coupling element (9) that the shorter lever arm is formed by an offset of the thin area (26) of the coupling element (9) produced in the longitudinal direction of the lever in relation to the thin areas (28) of the springs. The length of the shorter lever arm is determined only by the offset of the thin areas (26, 28) of the coupling element (9) and of the springs within the sheet thickness and can be very precisely manufactured by means of suitable manufacturing methods.
