A weight measuring device comprises a load detecting section for constantly detecting a load value (W) of a sample placed on a measuring pan; a moving average processing section for calculating a moving average (Wa) of the detected load value (W); a load changing rate calculating section for calculating a load changing rate per unit time (Wb) of the detected load value (W); a storage section for storing a first load change threshold (Wr1), a second load change threshold (Wr2) which is smaller th...
