摘要

A weighing device includes a weighing unit, a camera, an identifying unit, a product weight calculation unit, a label printer unit, a person sensor and a shopper-side notification unit. The weighing unit measures weight of a container and a product therein selected by a shopper to produce a weight value. The camera detects the size of the container. The identifying unit identifies the container based on size. The product weight calculation unit subtracts weight of the identified container from the weight value to calculate the weight of a product. The label printer unit prints a label displaying the price of the product based on the weight of the product. The person sensor detects whether or not the shopper is present at the weighing device. The shopper-side notification unit guides the shopper through purchasing and label printing in response to the person sensor detecting the presence of the shopper.
