    摘要： A weighing system includes a weight-dependently movable dial having a plurality of price scales each indicating the price-perweight on the basis of a different unit price. A projection screen is provided, and an optical system is movable relative to the dial in dependence upon a selected unit price and operative for projecting onto the screen a portion of that price scale which is most closely associated with the selected unit price. An indicator arrangement indicates the price of a weighed item on the projected portion of a price scale on the screen. The arrangement is fixable so as to indicate the starting values and end values of the projected price scale under no-load and fullload conditions of the machine, respectively, and it is also selectively and weight-dependently movable so as to indicate the starting value by a different end value of the projected scale portion under the respective load conditions, the end value being based upon a unit price different from that assigned to the projected scale portion.

    摘要： A computing scale system is provided for particular utility in connection with a point-of-sale merchandising terminal. The system may include a plurality of scales, each interconnected with a checkout counter and each associated with its own display unit. The display units each have electro-optic displays for displaying weight, price per unit weight and total value. The weight as measured by the scale is transmitted to the display unit for storage and display together with storage and display of price per unit weight information as entered by the display unit keyboard. Associated with one of the display units is a computing unit, which computes total price information for all display units on a time sharing basis. The computing unit generates display unit addresses at each of the display units, and the display units in turn respond with status information. So long as a display unit is in condition for servicing by the computing unit, the computing unit continues servicing that display. When a total value computation has been completed, then that total value is transmitted, together with the appropriate display unit address, to the display unit being serviced. If at any time during servicing, a display unit responds with improper status information, then the computing unit enters a program abort loop and begins servicing another display unit.

    摘要翻译： 提供了与销售点销售终端相关的特定实用程序的计算规模系统。 系统可以包括多个刻度，每个刻度与检出计数器互连，并且每个刻度与其自己的显示单元相关联。 显示单元各具有用于显示重量，单位重量价格和总价值的电光显示器。 通过刻度测量的重量被传送到显示单元用于存储和显示以及由显示单元键盘输入的每单位重量信息的价格的存储和显示。 与显示单元之一相关联的是计算单元，其在时间共享的基础上计算所有显示单元的总价格信息。 计算单元在每个显示单元处产生显示单元地址，并且显示单元依次响应状态信息。 只要显示单元处于由计算单元维修的状态，则计算单元继续维护该显示。 当总值计算完成时，将该总值与适当的显示单元地址一起发送到被维护的显示单元。 如果在维护期间的任何时间，显示单元以不正确的状态信息进行响应，则计算单元进入程序中止循环并开始服务另一个显示单元。
