PURPOSE:To efficiently perform combination weighing operation at high speed by providing weight sensors in two upper and lower stages and arranging plural hoppers for weighing articles. CONSTITUTION:Weight data obtain a weight sensor 1a for a weighing hopper and a weight sensor 2a for a pool hopper are converted by A/D converters 8a and 9a into digital values, which are inputted to a control part 10a. The control part 10a consists of a computer, etc., and is connected to a RAM 11a, and the control part receives a driving signal from an arithmetic part 13 consisting of a host computer to open and close a gate 3a for the weighing hopper, a weighing-hopper side gate 4a for the pool hopper, a gathering-chute side gate 5a for the pool hopper D, a shutter 6a, and a radiation feeder 7a. Then weight data obtained by control parts 10a-10n for respective measuring instruments are read in the arithmetic part 13 in order through a multiplexer 12 and combinational arithmetic operation is performed by a specific pattern. Consequently, the fast, efficient combinational weighing operation is enabled.
