Abstract

A weighing scale (1) for a retail store counter includes a housing (2), a load-receiving platform (3) on top of the housing, and operating components (27) enclosed therein, including a weighing cell (24). A load-transmitting mechanical connection (25) couples the weighing cell to the load-receiving platform. Analog and digital weighing electronics convert electrical weight signals of the weighing cell into digital weighing results. A touchscreen display panel (7, 22, 23) interacts with a human operator, and is configured as a layered assembly with a liquid crystal display (23), a projected capacitive (PCAP) touch screen (22) with a plurality of touch-sensing points, and a protective glass plate (21) on top of each other. The layered assembly is integrated horizontally in the load-receiving platform facing the human operator. The top surface operates as a load-receiving surface (45) a touch field keyboard (40, 41, 42, 47) and a display window (43, 46, 48).
