Abstract

PURPOSE:To prevent the input miss of the amount of money of sales and the person in charge of transaction, by giving information for the name of the person in charge of transaction and information of the amount of money of sales as calculating factors of a verify number. CONSTITUTION:When a balance key 24 is operated for registration of the balance, this operation information becomes a trigger signal of a discriminator 23. The number of the least significant digit of contents of an entry register 22 which are inputted by an entry key 14 is stored as the verify number in a verify number register 26, and contents of the register 22 except the least significant digit are stored as the balance in a balance register 25. A verify number generator 19 adds the decoded number of a selecting switch 13 for the person in charge and the number of each digit of the balance register 25 and takes one digit of the result to generate the verify number. Two verify numbers are compared with each other in a comparator 27; and only when they coincide with each other, contents of the balance register are inputted to a subtotal register 29 and are printed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic cash register used in restaurants and bars.

Generally, in a store equipped with such a (cage: L) register, each time an order is received from a customer, it is registered in the register, and the sales details and subtotal (sales amount) are recorded when handing over the ordered item to the customer. Give the customer the slip and have it in their possession. Next, when there is an additional order, a method is adopted in which the subtotal is entered as a balance in a register, the items of the additional order are registered, and the form is additionally written on the slip and handed to the customer. On the other hand, when the additional order is completed and the customer makes payment, the final subtotal will be the cumulative total of sales, so the transaction will be completed after the payment is received in an amount commensurate with this amount.

An example of the above transaction will be explained in more detail with reference to FIGS.

(1) Assume that the customer orders beer and cheese as the first order, and the person in charge covers them.

At this time, in the electronic cash register, beer and cheese are registered as sales for each item, with a subtotal of 950 yen, and at the same time, a slip containing the information shown in Figure 1A is created.
The person in charge will provide beer and cheese to the customer, and at the same time will also give this slip to the customer as the current sales slip.

12) Next, assume that the same customer orders an additional bottle of beer. The person in charge keeps the sales slip from the customer and registers the additional item (beer) at the cash register, and also prints the additional beer and the current subtotal amount of 950 yen on the slip. At this time, first, the current inventory is registered as the subtotal amount, and the sales of additional items of 450 yen are added to that amount to create a new subtotal 1.
Create a 4QQ circle as shown in Figure 1B. Then, additional beer and a slip are brought to the customer in the same way.

(3) Next, when the customer's order is finished and it is time to pay, if the customer pays 1,600 yen in cash, including a 200 yen tip, the tip and cash payment amount will be registered in the cash register. Then, the transaction for this customer ends.

"Nori" indicates the slip number, and "C" indicates the year, month, and day.

In the above transactions, the operation of registering the balance in the cash register is often performed. If this balance registration is incorrect, the effect will appear on all subsequent subtotal amounts and will be significant. Therefore, in order to prevent mistakes in entering balances, a verification digit is added to the subtotal amount, and a unique value calculated from the subtotal amount is printed at the same time as the subtotal. A method has been used in which a value in the verify digit is input together with the subtotal entry, and the balance is registered in the cash register only when it is determined that the subtotal amount is correct based on the value in the verify digit.

In Figure 1 &-1, the underlined numbers a to the right of the subtotal (amount) are the verified numbers, and in this case, when registering the balance, only if the numbers 96o6 or 14006 are entered are 950.1400, respectively. The numbers are registered as balances.

By using the method of registering the balance using the verified value for the subtotal amount as described above, input errors can be significantly reduced. However, in recent years, in view of improving the efficiency of store management and improving the work motivation of employees, there is a tendency to pay each service representative a commission based on their sales amount. In this case, the cash register needs to be able to provide data such as sales amounts and tips for each person in charge without error, and it is desirable that data on each sales person is also registered without error. For example, if we explain the transaction in Figure 1, the person in charge of service to this customer is Ham, so the person in charge needs to be registered as A when registering the balance and when registering the tip. It is.

The present invention aims to prevent errors in registering not only the numerical value of the subtotal amount but also the person-in-charge data, and will be described below with reference to an embodiment thereof.

In FIG. 2, 11 is a keyboard surface, 12 is a mode selection switch, 13 is a person in charge selection switch, 14 is a number key, and 16 is a function key.

With the above configuration, the register operator uses the mode selection switch 12 to specify the usage mode such as registration 1 inspection, payment, etc., and also uses the person in charge selection switch 13 to input predetermined keys such as M to E to this switch section. By inserting the information, the person in charge and the data at the time of registration are registered as the person in charge's sales.

Next, the unit price of the product and the balance are entered using the number keys 14, and the function keys 16 are used to register the balance, products, and create a slip.

In FIG. 3, 13 is the person in charge selection switch, 16
17 is a subtotal register, 17 is a subtotal print key, 18 is a switch decoder, 19 is a verification value generation adder, 2o is a print buffer, and 21 is a printer.

With the above configuration, the information of the person in charge selection switch 13 is converted into a numerical value by the switch decoder 18 and inputted to the verify numerical value generation adder 19. Further, the contents of the subtotal register 16 containing the cumulative sales amount of the product are also input to the verify value generation adder 19. Now, when the subtotal print key 17 is operated for the purpose of issuing a slip to a customer, this operation information is transmitted as a trigger signal to the verify value generation circuit 19.
If the addition of the numerical values of each digit of the subtotal and the number of decoders of the key of the person in charge are 1, the above-mentioned 1 is added and the last digit is taken as the verification number. Figure 1 shows the person in charge.

The number of verification for subtotal 950 is 9+6+o-1-1=
Take the last digit of 16 and get 6. Next, the verification number is added next to the least significant digit of the subtotal and transferred to the print buffer 20. In the print buffer 20, in order to make it easier to distinguish the verification number from a normal numerical value, the printer 21 is instructed to transfer and print only the verification number as an underlined lowercase letter. As a result of the above processing, subtotal 950-1 in Figure 1A is
is printed.

Next, the operation of registering balances including the verification number will be explained with reference to FIG. In Figure 4, 22 is a numeric register 1, 23 is a discriminator, 24 is a balance key, 26 is a balance register, 26 is a verify value, 1 is a comparator, 28 is an AND gate, 29 is a subtotal register, and other The same symbols as in FIG. 3 represent the same names.

Here, the information of the person in charge selection switch 13 is converted into a numerical value by the switch decoder 18 and inputted to the verify numerical value generator 19. Further, the numerical value inputted by the numeric key 14 in the numeric register 22 is input to the discriminator 23. Now, when the balance key 24 is operated for the purpose of registering the balance, this operation information becomes a trigger signal for the discriminator 23, and the value in the least significant digit of the number register 22 is sent as the verification value to the least significant digit of the register 26. The numerical value except for is stored in the balance register 26 as the balance. Here, the contents of the balance register 26 are input to the verify value generator 19 and the AND gate 28. In the verify value generator 19,
Number of decoders of person in charge selection switch 13 and balance register 2
Add each digit of the number 6 and take the last digit to generate a verify value. The verified value of this register 26 is compared with the verified number of the set value separated by the discriminator 23 in a comparator 27, and only when they are equal, the AND gate 28 is opened and the contents of the balance register 26 are transferred to the subtotal register 27.
9 and at the same time, the data is transferred to the printer 21 via the sofa 2o and printed.

If the comparator 27 determines that they are not equal, an error signal is output from the comparator 27 to indicate to the operator that the input is incorrect, and since the AND gate 28 is never opened, the balance register is The contents of 26 are neither entered into the subtotal register 29 nor printed. At this time, the operator can check the entered value and the person in charge key, correct any errors, and input again.

As described above, according to the present invention, it is possible to correctly register important numerical values of balances and to correctly set the person in charge selection switch, which is useful for streamlining management. In addition, the method of calculating the verification value is not to simply add the numbers of each digit and take the last digit as described in the above example, but also to calculate the verification value by multiplying each digit by its unique value and then adding it. Various methods can be considered in order to prevent the registration of verified numerical values, and various methods can be considered to print and enter the verified numerical value, such as printing the highest digit instead of the lowest digit, but the important point of the present invention is that , the information corresponding to the name of the person in charge of the transaction and the information on the amount of sales are used as a calculation factor for the number of verifications, and this makes it possible to prevent input errors in both the amount of sales and the person in charge of the transaction.
