PROBLEM TO BE SOLVED: To collect and weigh a predetermined amount of a sample to be weighed with good accuracy without causing clogging. SOLUTION: A weighing equipment 1 includes a weighing hopper 2, a first space 31a, a second space, a gate 35 and a separating panel. The weighing hopper 2 measures the weight of the sample to be weighed. The first space 31a, formed with a cylindrical member 31a, brings the sample to be weighed to the weighing hopper 2. The second space containing a cylindrical member 32 and a vibration feeder 33 brings a smaller amount of the sample to be weighed to the weighing hopper 2 than the first space 31a does. The gate 35, which is placed at the weighing hopper 2 side against the first and second space, can block the flow of the sample to be weighed from the first space 31a to the weighing hopper 2. The separating panel is a part of the cylindrical member 31 and separates the first space 31a from the second space. COPYRIGHT: (C)2009,JPO&INPIT
