Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to electronic cash registers.

(b) Conventional technology In electronic cash registers, in order to manage credit transactions, credit card details are printed on each customer's credit card using a slip printer, and credit management is performed using this card. (for example, JP-A-Sho
54-122063).

By the way, a credit card is configured such that a control number is set for each customer, and when a new credit card is issued, the operator enters the control number and prints it at the beginning of the credit card. There was a problem in that the operator sometimes forgot to input the management number, and the management number was not printed on the credit card.

(c) Problems that the invention aims to solve This invention was made to solve the above-mentioned problems, and is an electronic cash register configured so that the next process cannot be performed unless the operator inputs the management number. It provides:

(d) Means for solving the problem The present invention determines whether or not the input amount is zero when the credit amount from the previous time is input, and if it is zero, that is, in the case of a new credit transaction, the present invention determines whether the input amount is zero or not. is configured to prompt the user to enter the management number.

(E) Effect Since the present invention is constructed as described above, in the case of a new product, the next process cannot be performed unless the management number is input, thereby preventing the operator from making mistakes in inputting the management number.

(f) Examples Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a keyboard for inputting registration data, which is composed of a numeric keypad for inputting amounts, a key for each product category, a key for each transaction, and a person-in-charge key. Reference numeral 2 denotes a control circuit which performs various controls based on key signals input from the keyboard 1 in accordance with programs in a program memory 3 in which processing programs are stored in advance, and is composed of a microprocessor. 4
1 is a memory in which registered data inputted from the keyboard 1 is stored classified by product department, transaction, person in charge, etc., and writing or reading of the data is controlled by a control circuit 2. 5 is keyboard 1
This is a display device on which the amount data inputted by the control circuit 2 and the data processed by the control circuit 2 are displayed. Reference numerals 6 and 7 refer to receipt printers that print sales data such as amount data input from the keyboard 1 and data processed by the control circuit 2 on receipt paper and journal paper in a predetermined format under the control of the control circuit 2. and a journal printer. 8 is a slip printer that prints sales data on a credit card 9 as shown in FIG. 2 at the time of credit sale; when the credit sale key is operated on the keyboard 1,
Under the control of the control circuit 2, printing is performed on the credit card in a predetermined format. The printing formats of the printers 6, 7, and 8 are preset in the program memory 3, and the control circuit 2 controls the printing of each of the printers 6, 7, and 8 so that the formats are set.

Next, the operation of the present invention having such a configuration will be explained.

First, in normal registration work, when a customer inputs the amount of each product purchased from the keyboard 1 and operates the product category key, the input amount is displayed on the display 5 and the receipt printer 6 is printed by the journal printer 7.
Further, the control circuit 2 adds up the amounts input into a predetermined area of the memory 4 in accordance with the operated product department key. When the registration is performed in this way and the total key is operated at the end, the control circuit 2 totalizes the amounts input so far and displays the total amount on the display 5, and also displays the total amount on the printer 6,
7 to print and issue a receipt. There, cash is received from the customer, the transaction for that customer is completed, and registration work begins for the next customer.

However, at this time, if the customer wishes to make a credit sale, prepare the customer's credit card 9, attach it to the slip printer 8, operate the credit key on the keyboard 1, and then display the credit amount up to that point on the keyboard 1. Enter more information. In this case, since it is a new credit card, the number of printed lines data is not input, so the control circuit 2 proceeds from step (S1) to step (S5) in FIG. 3 via (S3) and (S4). When the control circuit 2 detects data input from the keyboard 1, it determines whether the input data is "0" or not in step (S5), but if "0" is input with a new credit card, Proceeding to step (S6), the display 5 displays a request to input the management number. Then, when the operator follows the display on the display 5 and inputs the management number, for example "12345", from the keyboard 1 and operates the setting key "#", the control circuit 2 detecting the setting key signal sends the slip printer 8 in step (S9). The input management number is printed at the beginning of the credit card 9 as shown in FIG. 2a. When the printing of the management number is completed, the control circuit 2 goes to step (S10).
Then, the customer's registration data stored in the buffer memory in the control circuit 2 is sequentially read out, and the slip printer 8 is controlled to print in a predetermined format stored in the program memory 3. At this time, the control circuit 2 counts the number of printed lines in step (S10), reads the print data from the buffer memory in step (S11), and detects whether or not it is the final data in step (S12). By repeating the steps of proceeding to step (S13) and printing the contents read from the buffer memory, printing is performed as shown in FIG. 2a. In FIG. 2a, the printing format is programmed to print the details on the left and the results on the right. Then, when the last data in the buffer memory is read,
The control circuit 2 proceeds from step (S12) to step (S14) and detects whether the last line is set to be printed on the left or right side. Assuming that it is now set to print on the right side, the control circuit 2 proceeds to step (S15) and prints the data read out from the buffer memory on the right side as shown in FIG. Print the number of lines that were previously printed. This print data allows the operator to easily know how many lines have been printed. Figure 2a
In this case, 8 lines are printed. Also second
In the case of figure a, the customer is a new customer, and the print line counter is set to ``0'' in step (S3), and the credit card is not fed blankly as in step (S2). Shows the state printed from the beginning of the card. This credit card is kept in the store as a ledger and is used to manage credit sales.

Next, when the above-mentioned customer makes a purchase and wishes to sell on credit again at a later date, the customer's credit card is taken out and printed on the slip printer 8 in the same manner as described above, but in this case, the previous printing continues. Since it is necessary to print on the credit card, following the operation of the credit key, the number of lines to be printed that was printed on the last line of the previous time is inputted from the keyboard 1, and the total amount of credit sales up to the previous time is inputted. Then, the control circuit 2 that has received the input data sets the print line number data input to the print line number counter in step (S2), and prints the credit card set at the start position by the number of lines equal to the set value. Send the card. and,
In this case, since the input credit amount data is not "0", the process proceeds from step (S5) to step (S10), and the registered data read from the buffer memory in the same manner as described above is printed out sequentially as shown in Figure 2b. Finally, the total credit amount input up to the previous time is added to the current total amount, and the final credit amount is printed on the last line.

(g) Effects of the invention As mentioned above, the electronic cash register of the present invention is configured so that the next process cannot be performed unless the management number is entered in the case of a new credit card. Input errors can be prevented.
