Abstract: A combination weighing apparatus (1) according an embodiment includes: a conveyance unit (2, 31 to 3n) that conveys articles (M) given from an outside; a plurality of weighing hoppers (61 to 6n) that temporarily store the articles (M) conveyed by the conveyance unit (2, 31 to 3n) and then discharge the articles (M) downstream; a weighing unit (71 to 7n) that weighs a weight value of the article (M) stored in each of the plurality of weighing hoppers (61 to 6n); and a control unit (20) that performs combination calculation based on a plurality of the weight values measured by the weighing unit (71 to 7n) and a target value (X) and discharges a specific article (M) selected by the combination calculation from the weighing hopper (61 to 6n), wherein the control unit (20): multiplies an average weight (m) value per unit number of articles (M) within a predetermined period by the number (C) of articles (M), calculates a multiplication result closest to the target value (X) from among results of the multiplication as a reference weight value (Tcm), and performs predetermined processing based on a difference between the target value (X) and the reference weight value (Tcm).

Abstract: A combination weighing device includes: an electroconductive plate opposed, with an interval, to an electroconductive part enabling detection of water intrusion inside the combination weighing device; a voltage wire for application of voltage to the electroconductive plate; and a detector that detects a potential difference between the electroconductive part and the electroconductive plate, wherein the detector or a controller of the combination weighing device determines presence or absence of water intrusion inside the interval, based on the detected potential difference.
