[Scope of Claim for Utility Model Registration] In a weighing device configured to lift an object to be weighed made of a ferromagnetic material using an electromagnet and drop it onto a weighing machine, When the difference between the actual weight and the target weight detected by the comparison means is larger than the maximum weight that the lifting electromagnet can lift for one time, the lifting electromagnet is moved to the maximum magnetic force. outputs a signal that turns on and off in the state, and when the difference between the actual weight and the target weight becomes smaller than the maximum weight that can be lifted by the lifting electromagnet for one time,
a control unit that outputs a magnetic force reduction signal that gradually reduces the magnetic force of the lifting electromagnet, and outputs a magnetic force increase signal that increases the magnetic force of the lifting electromagnet when the difference between the actual weight and the target weight becomes 0; A control device for a weighing device, comprising: electromagnet driving means for outputting a supply current to a lifting electromagnet in accordance with a signal output from the lifting electromagnet.
