Abstract

A first cash register operating in a registration mode is connected by a communication line to a second cash register operating in a calculation mode to serve customers forming a waiting line extending from the first cash register to the second. Sales data are registered by the first cash register, with the data of an earliest one of the customers being displayed on a first display unit and the sales data of all the customers being stored sequentially into respective second storage areas when a communication line is busy. When the line becomes available, the sales data are transmitted to the second cash register from the second storage areas sequentially. The second cash register stores the transmitted sales data into third and fourth storage areas in succession and provides a simultaneous display of the sales data stored in the fourth storage areas on respective window areas of a second display unit. An adder sequentially calculates the sales data stored in the fourth storage areas in response to operation of a control key. Each cash register is operable independently in the registration and calculation modes.

Claims

1. A cash register comprising:

a keyboard having a plurality of sales item keys for generating sales data for each of a plurality of customers and a plurality of control keys;

memory means having a plurality of storage areas corresponding respectively to said customers;

calculating means;

a controller means for addressing said storage areas to store said sales data of said customers into said storage areas and causing said calculating means to calculate the sales data stored in each of said storage areas in response to operation of one of said control keys; and

display means having a plurality of display windows respectively corresponding to said storage areas and connected to said controller means for displaying in the corresponding display windows a plurality of sales data stored in said storage areas and a plurality of data resulting from the calculation by said calculating means.

2. A cash register comprising:

a keyboard having a plurality of sales item keys for generating sales data for each of a plurality of customers and a plurality of control keys;

memory means having a plurality of first storage areas corresponding respectively to said customers and a plurality of second storage areas corresponding respectively to said customers;

mode setting means for selectively establishing registration and calculation modes of operation;

calculating means;

a controller means responsive to said registration mode for storing said sales data of said customers into said first and second storage areas and for transmitting sales data from said second storage areas to a communication line when said line is available,

said controller means responsive to said calculation mode for storing said sales data of said customers into said second storage areas in succession, for transferring the sales data to said first storage areas, and for causing said calculating means to calculate the sales data stored in said first storage areas in response to operation of one of said control keys and rewriting said first storage areas with the calculated sales data; and

display means having a plurality of display windows corresponding respectively to said first storage areas and responsive to said registration mode for displaying the sales data stored in one of said first storage areas and responsive to said calculation mode for displaying the sales data stored in said first storage areas in said display windows.

3. A cash register as claimed in claim 2, wherein said mode setting means further establishes a dual mode of operations, wherein said controller means is responsive to said dual mode for storing said sales data into said first storage areas so that the sales data of a plurality of customers are stored respectively in said first storage areas and causing said calculating means to calculate the sales data stored in said first storage areas in response to operation of said control key, and wherein said display means is responsive to said dual mode for displaying the sales data stored in said first storage areas in said display windows.

4. A system of cash registers interconnected by a communication line, comprising:

a first cash register comprising;

a first keyboard having a plurality of sales item keys for generating sales data for each of a plurality of customers;

PG,23

first memory means having a plurality of first storage areas corresponding respectively to said customers and a plurality of second storage areas corresponding respectively to said customers;

first controller means for storing said sales data into said first and second storage areas and for transmitting sales data from said second storage areas to said communication line when the line is available;

a first display unit for displaying the sales data stored in said first storage areas, and

a second cash register comprising;

a second keyboard having a plurality of second control keys;

second memory means having a plurality of third storage areas corresponding respectively to said customers and a plurality of fourth storage areas corresponding respectively to said customers;

calculating means;

second controller means for storing the sales data transmitted from said first cash register into said third and fourth storage areas in succession and for causing said calculating means to calculate the sales data stored in said fourth storage areas in response to operation of one of said second control keys and rewriting said fourth storage areas with the calculated sales data; and

a second display unit having a plurality of display windows corresponding respectively to said fourth storage areas for displaying the sales data of said fourth storage areas in said display windows.

5. A system as claimed in claim 4, further comprising a third display unit multiplied to said second display unit, said third display unit being located remote from the location of said second display unit.
