A scale has a display unit for digitally displaying weights, price per unit weight, and price data in sequential fashion and preferably using common digit display portions of the display unit for each of these items of data. A weight computing unit computes weight at automatically repeated periods. A manual entry price unit having a keyboard is provided for the entry of price per unit weight data. A calculator unit is supplied with data from the weight computer unit and manual entry price unit. With this information, the calculator unit computes price data. The manual entry price unit and weight computing unit have a commmon input to the calculator unit. This arrangement together with the provision of a selector unit connected to the weight computing unit and the manual entry price unit allows the passage of price per unit weight and price data sequentially after the weight data has been unchanged during at least two repeated periods. The display unit is supplied with the sequential data from the calculator unit and displays weight, price per unit weight and price sequentially. |
