PROBLEM TO BE SOLVED: To provide an electronic balance that enables simplification of work during assembly.SOLUTION: An electromagnetic coil 5 is attached to a movable part 2. A circuit board 6 is attached to the movable part 2 and connected to the electromagnetic coil 5. A wireless power transmission part 72 is attached to a fixing part 1, and wirelessly transmits power. A wireless power reception part 71 is attached to the movable part 2, and power which is wirelessly received from the wireless power transmission part 72 is supplied to the circuit board 6. Unlike such a configuration that the circuit board 6 is attached to the fixing part 1 and the electromagnetic coil 5 is attached to the movable part 2, soldering between the circuit board 6 and the electromagnetic coil 5 during assembly is not necessary, thus enabling simplification of work during assembly.SELECTED DRAWING: Figure 1 |
