Abstract: A weighing apparatus (100) comprise a large throw-in weighing hopper (21) which is fed with objects having a weight which is less than a target weight of the objects, holds the objects which are weighed, and discharges the weighed objects; a plurality of medium throw-in weighing hoppers (64, 65, 66, 44) which are respectively fed with the objects having weights adjusted with a different ratio, hold the objects for which combination calculation is performed based on the weights of the objects, and discharge the objects based on a result of the combination calculation; and a loss-in hopper (42) which is used in loss-in weighing and performs loss-in discharge of the objects.

Abstract: A control device for a robot arm is designed such that, based on information on a transportation state database in which information on a transportation state of a person operating the arm is recorded, an impedance setting unit sets a mechanical impedance set value of the arm, and an impedance control unit controls a mechanical impedance value of the arm to the mechanical impedance set value thus set.

Abstract: A printer operatively associated with an electronic weigher includes an input unit having numeric keys or format keys, a memory device storing a plurality of programs for controlling positions at which data are to be printed on a label as well as the size of the printed data, each program corresponding to a different label format, reading means for reading out of the memory device a program corresponding to a format designated by operating the keys of the input unit, and a printing mechanism for printing predetermined data on a label at a predetermined position of the label on the basis of the program read out of the memory device.
