Abstract
In an electronic balance used for a scale of a weighing unit of a feeder, a wiring member for supplying an electric signal from a control device to a driving source of a feeder unit is provided so as not to adversely affect a weighing pan. A flexible substrate using as the wiring member has one end provided with an electric signal input substrate and has the other end provided with an electric signal output substrate. A U-shaped curved portion is formed near the electric signal output substrate and arranged below a pan boss. The electric signal output substrate is fixed to the pan boss, the electric signal input substrate is fixed to a fixed frame, and the flexible substrate is provided in a case that houses a sensor unit.
Claims4
