Description

[Detailed Description of the Invention] This invention separately records the sales amount of the previous customer, interrupts the registration operation of the current customer, calls up the sales amount of the previous customer, and completes the settlement process. Regarding electronic cash registers.

The performance of cash registers has improved significantly in recent years, improving the efficiency of customer processing through cash registers.

However, especially in supermarkets, the time from when the customer's total amount is calculated until the customer prepares the money is each customer's operating time, and it is difficult to simply try to shorten it mechanically. be. Therefore, a considerable amount of waiting time is often required. In such cases, we will temporarily suspend the payment processing for the customer,
By being able to proceed with the registration process for the next customer, it becomes possible to considerably shorten the waiting time for subsequent customers. However, with current cash registers, registration processing for subsequent customers cannot be started until the registration processing for the previous customer is completed. If you are forced to do so, the total sales amount of the previous customer will be cleared, and you will not be able to process money such as calculating change for that customer. Therefore, in order to eliminate such drawbacks, the present invention provides a memory for storing the total sales amount for the most recent customer, temporarily stores the total sales amount for the most recent customer, and temporarily postpones subsequent money delivery processing. Then, when the previous customer submits money, the registration process for the current customer is temporarily suspended, and the total sales amount of the previous customer is recalled to complete the money transfer process. It is something. In this manner, the present invention aims to speed up customer processing using a cash register by effectively utilizing the waiting time while a customer prepares money for registering the next customer. be. Next, the present invention will be explained based on an embodiment and its drawings together with the operation of a cash register.

In FIG. 1, 1 is a department key for specifying one of the many product departments, 2 is the only numeric key for inputting numerical values such as amount and quantity, 5 is a mode switch for setting the operating mode of the cash register, 6 is switch 5 and each control key, department key 1,

Z register, 11 is an arithmetic device that performs calculations on each data and its control, 12 is an input/output control device for the display device 13 and printer 14, and 13 and 14 are characters for inputting necessary numerical values such as amount, quantity, department number, etc. a display device and a printer for displaying or printing; 15 is a main storage device; at least an address control device 15X; department totalizers 15a installed for the number of product departments; and an itemizer 15a for storing the sales total of one customer; 21 is a current total key that starts the operation of settling the sales total of one registered customer (current customer); 22 is the contents of the call memory 15c; A recall key 23 is used to read out the total sales of the previous customer and to start calculation of change, and 23 is a subtotal key for calculating the sales subtotal of the same customer. FIG. 2 is a flow diagram of the operation of the cash register and each function when the call-back function according to the present invention is used.
The callback function will be explained below according to the operation flow shown in this flowchart. In the diagram, customer 1 means the previous customer and customer 2 means the current customer, and each represents the handling period. 1M also stores the contents of the itemizer 15b in the RM call memory 15c.
represents the content of After first registering the sales amount of each product to the first customer, the cash total key 21 is pressed (101).
The current total signal from the current total key 21 is gated by the key signal control device 6 and connected to the computation device 11. When the logic circuit of the arithmetic unit 11 receives the current total signal, it starts the current total adjustment operation described below. The arithmetic unit 11 transfers the IM stored in the itemizer 15b to the call memory 15c via the X register 8, and clears the itemizer 15b (102). Next, change the contents of X register 8 (IM) to Y
The contents of the totalizer 15d are read out to the X register 8, and both are transferred to the adder 11 in the arithmetic unit 11.
A is used to sum up the total sales, and the total sales are written back to the totalizer 15d to add up the total sales (102). As a result of this operation, the normal registration operation for the first customer is completed, and the sales total is stored only in the call memory 15c, and later if necessary,
It is used when transferring money for customers by activating the calling function. In this state, registration of the sales of the subsequent customer, Customer B, is started (103). The registration process for the customer is no different from the normal registration process, and starts and continues as usual. However, as mentioned above, when calculating the current amount for Customer 2, the total sales of Customer 2 is cleared in the re-call memory 15c and the total sales of Customer 2 is stored there, so it is no longer possible to calculate the total sales of Customer 2. You will not be able to perform a recall. Therefore, we have to wait for Customer A to submit the payment without paying Customer B's cash amount. When the first customer submits the payment, the cashier presses the recall key 22 (
104). The control signal generated from the recall key 22 is gated by the key signal controller 6 to activate the recall circuit of the computing device 11. This will temporarily suspend the currently ongoing registration status for the customer and interrupt the operation of the callback function. The arithmetic device 11 calls the call memory 15c, reads its contents into the X register 8, passes them through the input/output control device 12, and displays them on the display device 13 (105). The cashier thereby learns the sales amount of the first customer and compares it with the amount submitted by the customer. If change is not required, the process for Customer A is completed and the registration process for Customer B is immediately continued (106, 109
, 110). That is, as shown in Fig. 2, just like the normal registration operation, simply enter the sales amount to be registered next to the customer using the numerical key 2 (106), and then press the department key 1.
By pressing (109), the customer registration operation can be continued (110). If change is required, input the deposited amount using numerical keys 2 (106). This is stored in the Z register 7, and then the recall key 2 is pressed again.
When 2 is pressed (107), the numerical value stored in the Z register 7 is regarded as the deposit amount and used for monetary calculation. The recall circuit in the arithmetic unit 11 uses the adder 11A to extract the RM stored in the X register 8 from the deposited amount.
is subtracted and the result is returned to the X register 8 as change (108). At the same time, the call memory 15c is cleared (108). The change stored in the X register 8 is displayed as change on the display device 13 via the input/output control device 12. In the case of a recall operation, no printing is performed in any case, and there is no effect on the registration results of the second customer.Therefore, the process for the first customer is completed by handing over the change, and after that, the first customer's registration result is not printed. Just continue the registration operation (110
). In this way, the cashier can recall the previous customer's sales total and calculate change by simply pressing the recall key 22, which reduces the burden on the cashier and improves the flow of customer handling. can be advanced very quickly.
