Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic cash register used in restaurants, bars, etc.

Conventional Technology In general, stores equipped with such (cash) registers register each order from a customer in the register, and also record the sales details and subtotal (sales amount) when handing over the ordered item to the customer. Hand over the written slip to the customer and have him or her keep it. 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 amount becomes the cumulative total of sales, so the transaction is completed upon receipt of payment commensurate with this amount.

Problems that the invention aims to solve However, in recent years, in view of improving the efficiency of store management and improving the work motivation of employees, there has been a tendency to pay each service person a commission based on their sales amount. . In this case, the cash register needs to be able to accurately provide data such as the sales amount for each person in charge, as well as chips, etc., which is customary in Europe, America, etc., and also to register the data of each sales person without error. It was hoped that it would be done. For example, it is necessary for the service person who first interacts with a customer to be registered as A without error when registering the balance or when registering chips.

In order to solve the above-mentioned problems, the present invention checks whether the customer is the first service person to contact the customer at the time of balance registration, chip registration, etc., and prevents mistakes in posting charges when additional sales are made. The purpose is to provide an excellent electronic cash register that can be checked.

Means for Solving the Problems In order to achieve the above object, the present invention provides a discriminator which, by inputting a balance key signal, discriminates the last digit entered by a numeric key as a verification-only digit. A verification value generator that outputs a one-digit number using a specific arithmetic formula by inputting a number other than the last digit and the person in charge code specified by the person in charge selection switch, and the output of the verification value generator. It is equipped with a comparator that compares the signal with the signal of the number dedicated for verification of the discriminator.

Effects According to the present invention, with the above configuration, when the comparator matches, the subsequent numbers are set, and when they do not match, the comparator outputs a mismatch signal and inputs it again to the discriminator. This will help prevent mistakes and incorrect input.

Embodiment FIGS. 1A to 1C are slips using an electronic cash register according to an embodiment of the present invention.

(1) First, let's assume that a customer orders beer and cheese as their first order, and Person A serves them. At this time, one item each of beer and cheese, for a subtotal of 950 yen, is registered as sales for person A in the electronic cash register, and at the same time,
A slip with this information written on it will be created, and the person in charge will provide the beer and cheese to the customer and at the same time hand over this slip to the customer as the current sales slip.

(2) Next, suppose that the same customer from earlier orders an additional bottle of beer. Person A receives the sales slip from the customer and registers an additional item (beer) in the cash register, and also records the additional beer and the subtotal amount at the time of closing on the slip.
Print 950 yen. At this time, first, the current balance 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 amount of 1400 yen as shown in FIG. 1B. Then, additional beer and a slip are brought to the customer in the same way.

(3) Next, when the customer's order is completed and it is time to pay, if the customer pays 1,600 yen (including 200 yen in chips) in cash, the chips and cash payment amount will be registered in the cash register. Then, the transaction for this customer ends. Note that b indicates the slip number and c indicates the year, month, and day.

In the transactions shown in Figure 1 A to C above, the person in charge inputs the person in charge code and balance, generates a verification digit (a number dedicated to verification), and compares it with the previous verification digit. This prevents staff errors and balance entry errors.

The configuration will be explained with reference to FIGS. 2 to 4.
Figure 2 is a front view of the keyboard surface of this embodiment;
The figure is a block diagram of verification value creation, and FIG. 4 is a block diagram of verification value verification.

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 numeric key, and 15 is a function key.

With the above configuration, the register operator specifies the usage mode such as registration, inspection, payment, etc. using the mode selection switch 12, and also uses the person in charge selection switch 1
3, by inserting predetermined keys such as A to E into this switch section, the person in charge and the data at the time of registration are registered as sales of the person in charge. Next, the unit price of the product and the balance are entered using the number key 14, and the function key 15 is used to register the balance, product, and create a slip.

In FIG. 3, 13 is the person in charge selection switch, 16 is a subtotal register, 17 is a subtotal print key,
18 is a switch decoder, 19 is a verification value generator, 20 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 verification numerical value generation adder 19. Also, a subtotal register 16 containing the cumulative sales amount of the product.
The contents of are also input to the verification 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 becomes a trigger signal for the verification value generation circuit 19.
Adding the numerical values of each digit of the subtotal amount and assuming that the number of decoders of the person in charge key A is 1, the above 1 is added and the last digit is taken as the verification number. In Figure 1, person in charge A,
The verification number for the subtotal amount of 950 is 9+5+0+1=
Take the last digit of 15 and get 5. Next, the verification number is added next to the least significant digit of the subtotal amount and transferred to the print buffer 20. In order to easily distinguish the verification number from a normal numerical value, the print buffer 20 instructs the printer 21 to transfer and print only the verification number as an underlined lower case letter. By the above processing, the subtotal amount 950 ⁵ of 1 in FIG. 1A is printed.

Next, the operation of registering the balance amount including the verification number will be explained with reference to FIG. In Figure 4, 22
is a numeric register, 23 is a discriminator, 24 is a balance key, 25 is a balance register, 26 is a verification value, 27 is a comparator, 28 is an AND gate, 29 is a subtotal register, and the other symbols are the same as in Figure 3. shall represent the same name.

Here, the information from the person-in-charge selection switch 13 is converted into a numerical value by a switch decoder 18 and inputted to a verification 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 lowest digit of the number register 22 is sent as the verification value to the lowest digit in the register 26. The numerical value except for is stored in the balance register 25 as the balance. Here, the contents of the balance register 25 are input to the verify value generator 19 and the AND gate 28. In the verification value generator 19, the operator selection switch 1
The decoder number of 3 and each digit of the numerical value of the balance register 25 are added, and the last digit is taken to generate a verification numerical value. The verification value of this register 26 is
The verification number of the set value separated by the discriminator 23 is compared in the comparator 27, and only when they are equal, the AND gate 28 is opened and the contents of the balance register 25 are inputted into the subtotal register 29, and at the same time, the contents of the balance register 25 are inputted to the subtotal register 29. It is transferred to the printer 21 and printed.

If the comparator 27 determines that they are not equal, an error signal is output from the comparator 27, indicating to the operator that the input is incorrect, and since the AND gate 28 is never opened, the balance register is The contents of 25 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 this embodiment, 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. The verification value can be calculated by simply adding the numbers of each digit and taking the last digit as described in the example above, or by multiplying each digit by its unique value and then adding it. Various methods can be considered to prevent the registration of numerical values, and various methods can be considered for printing and setting verification values, such as printing the most significant digit instead of the least significant digit, but the important points of the present invention are as follows. The point 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 calculation factors for the verification number, and thereby, input errors in both the amount of sales and the person in charge of the transaction can be prevented.

In this embodiment, the final digit is used as the verification number digit, but it is also possible to increase the number to two digits, etc., or to use the first digit as the verification number digit.

Effects of the Invention As is clear from the description of the above embodiments, the present invention includes a verification value generator that generates a single-digit verification-only number from a plurality of digits using a specific arithmetic expression, and Enter the balance and the person in charge code to generate matching numbers,
The configuration is such that the verification numbers are compared with the previous verification-only numbers, so when a discrepancy signal is output from the verification value generator, the person in charge code and balance can be entered again to prevent mistakes in the person in charge and prevent incorrect input. It has the effect of being able to.
