Abstract

The present invention provides an electronic meter apparatus. The apparatus comprises a scale; a manipulator, wherein the manipulator comprises a display screen which is connected to a power supply, a control key group connected to the power supply and the display screen, an article key group connected to the control key group, and a number key group connected to the control key group and the article key group; and a power supply. According to the electronic meter apparatus, the power supply has very high conversion efficiency, power supply for a system can be achieved by using only 1-2 dry cells, the size and the weight of an electronic balance is greatly reduced, and the portable design is realized.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to an electronic metering device. Background technique [0002] Electronic scales can be seen everywhere in people's daily life. For example, electronic scales are required to weigh items in supermarkets, fruit stores and other places. In these places, there are various kinds of articles, and the existing electronic scales are large in volume and weigh 2-3 kilograms. The volume and weight are mainly occupied by batteries, and 4-6 batteries are often needed to meet the power supply needs. [0003] How to provide an electronic metering device with a small battery size and energy saving is an urgent problem to be solved at present. Contents of the invention [0004] The invention provides an electronic metering device, which solves the problems of large volume and heavy weight of the existing electronic metering device. [0005] Technical scheme of the present invention is reali...
