Abstract: A product weight calculation system includes an accommodation section, a door portion that switches between a closed state and an open state, a weight detector that detects a weight of the products accommodated in the accommodation section and outputs an output value, a door detector that detects a state of the door portion, and a product weight calculation unit that calculates a weight value of a product taken out from the accommodation section based on a difference between a first output value and a second output value when an output value of the weight detector decreases from the first output value and becomes the second output value in a case where it is determined from a detection result of the door detector that the door portion is transitioned from the open state to the closed state, and sets an output value after the calculation as a new first output value.
