Cash processing method and system

In a cash processing system comprised of a plurality of cash processing units, wherein the cash processing units are coupled together via data transmission lines and one unit may be designated a master unit and all others slave units, with each cash processing unit having:

• a coin sorter/counter means for accepting coins collected from cash registers following sales transactions, for sorting said coins into like denominations, and for counting the sorted coins;
• a bill counter means for accepting monetary bills of like denomination collected from cash registers through sales transactions, and for counting such bills for each denomination;
• an arithmetic unit for accepting count data from the coin sorter/counter means and bill counter means and aggregating such data with other sales data into processed sales data and having a buffer memory area and data memory area for storage of such data;
• and
• an operation unit having a keyboard for data entry, including keys for inputting the code number of a sales department to which the coin and bill count data corresponds and an accept key for prompting the transfer of processed sales data from the buffer memory area of a slave unit to the data memory area of the master unit,
• a cash processing method comprising the steps of:
• designating one cash processing unit of the said plurality of cash processing units as a master station and designating the remaining units as slave units;
• coupling the arithmetic unit of each slave unit to the arithmetic unit of the master station for the transfer of data by means of said data transmission lines;
• transferring the processed sales data stored in the buffer memory area of the arithmetic unit of a slave cash processing unit, together with the corresponding code numbers, to the master station data memory area by way of the data transmission lines in response to operation of the accept key of a slave unit;
• and
• aggregating, by the arithmetic unit of the master station, the sales data transferred from each of the slave units along with the sales data from the cash processing unit of the master station, for each of the sales department code numbers corresponding to sales data.

A cash processing system comprising:

• a plurality of cash processing units, one of each said cash processing units being designated as a master station and the rest of said cash processing units being designated as slave stations, each processing unit having:
• a coin sorter/counter for sorting coins collected through sales in cash registers by each kind of denomination and counting each of the sorted coins;
• a bill counter for counting bills collected through sales in the cash registers for each kind of denomination;
• an arithmetic unit for aggregating count data as sales data obtained by said coin sorter/counter and said bill counter and storing the aggregated count data into a buffer area thereof, the arithmetic unit of each slave station being connected to the arithmetic unit of the said master station by means of communication lines;
• an operation unit having keys for inputting an associated code number of a sales department to which a cash register whose aggregated count data belongs, and an accept key for initiating further processing of count data, to be operated upon completion of storing of said aggregated count data and inputting of said associated code number;
• and
• a cash processing means for operating said plurality of cash processing units, including means for:
• transmitting the data stored in said buffer area together with said associated code number to said master station by way of said communication lines in response to the operation of said accept key provided in said slave station;
• and
• aggregating, by the arithmetic unit of said master station, aggregated count data transmitted from each of said slave units and aggregated count data obtained in the cash processing unit of said master station with respect to each of said code numbers, thereby independently obtaining an aggregated count of coins and bills from each sales department.
