A sales data transmission system includes a sales data processor such as a scale of the type capable of calculating and displaying a sales price from a unit price and a measured weight, a communication device which is made a part of this data processor and transmits and receives signals indicative of sales data and a memory unit which serves not only to receive and store the sales data transmitted from the communication device but also to transmit the stored sales data back to the communication device in response to a request signal therefrom.

Sales data transmission system

A manual combinatorial weighing apparatus having one or more weighing devices housed in a casing with each weighing device having a scale plate for placing articles thereon, and indicators associated with the weighing devices for indicating selected weighing devices. As many weighing devices in casings as desired by the user are provided in a desired layout. Weight data items of the articles put on the scale plates are combined to find a weight combination giving a desired total weight. The selected weighing devices are indicated by the indicators, which are held energized until the articles are removed from the selected weighing devices.

Manual combinatorial weighing apparatus

A combinatorial weighing method includes reading and storing output data from a plurality of weighing machines, and monitoring the weighing state of each weighing machine at all times on the basis of the stored data. When performing a combinatorial calculation, weight data from weighing machines in a stable state is read and these weight data participate in the combinatorial calculation. A combinatorial weighing apparatus for practicing the foregoing method has a reading circuit for constantly reading output data from each of the weighing machines, a memory for storing the read data, a sensing circuit for sensing whether each weighing machine is in a stable state based on the stored data, and an arithmetic circuit for executing a combinatorial calculation based upon weight data from those weighing machines in a stable state.

Combinatorial weighing method and apparatus therefor

A control system for a combinatorial weighing or counting apparatus includes a main central processing unit for effecting a combinatorial arithmetic operation, and a plurality of individual drive unit central processing units. The drive unit central processing units are associated respectively with driver units of the weighing machines and connected to the main central processing unit for controlling the drive units, respectively. Operation commands delivered from the main central processing unit to the individual drive unit central processing units, are set by interrupt processes of the individual drive unit central processing units at all times. The control system for the combinatorial weighing or counting apparatus includes a main computer for chiefly effecting a combinatorial arithmetic operation on weight data from a plurality of the weighing machines to select a combination of weighing machines including articles having an optimum added value with respect to a target value. The control system also includes other computers for controlling auxiliary operations such as a supply of articles to the weighing machines or a discharge of the articles therefrom; thus each of the main computer and the other computers carries out its own share of processing functions.
