Description

Description: (a) Technical Field The present invention relates to an electronic cash register (hereinafter referred to as ECR) that prints a date on a receipt at the end of a transaction.

(B) Prior Art and Its Deficiencies In the conventional ECR, the registration date printed on the receipt was completely linked with the clock and the registration date was updated the next day after midnight. However, in the case of a store whose business hours extend from midnight to midnight, the actual business day is one day even if it is open for two days according to the calendar, and the receipt / journal Even if you try to sort out the sales by looking at it, there is a drawback that it is difficult to sort because the date after midnight on the previous business day and the time before midnight on the current business day are the same.

(C) Object of the Invention An object of the present invention is to eliminate the above-mentioned drawbacks by not updating the registration date printed until the shop is closed even after midnight.

(D) Structure and Effect of the Invention This invention stores the business extension time after midnight in advance in the memory of the ECR, and when the registration date is recorded on the receipt, the preset time from the actual time is stored. If the result of the subtraction becomes negative, the date obtained by subtracting one day from the actual date (current day) is printed on the receipt.

With this configuration, according to the present invention, if the preset extension time is set to the business extension time of the store, the registration date is updated during the business hours of the store even after midnight. Disappear. For this reason, there is an advantage that the totaling of sales becomes very easy and the customer does not feel unnatural.

(E) Embodiment FIG. 2 is a schematic block diagram of an ECR which is an embodiment of the present invention. In the figure, CPU1 is a ROM that stores programs
2. A RAM 3 for storing total sales, a display 4, a printer 5 for issuing receipts, and a keyboard 6 are connected.

FIG. 3 is a layout view of the keyboard 6. A key switch 60 can be switched to any one of a program mode, a registration mode, an inspection mode, and a settlement mode. 61 is a department key, and up to 5 departments can be specified in this ECR. 62 is a ten-key pad to enter the amount of money. 63 is a function key. 63a of these
Is a key operated during margin trading, 63b is a key operated during selling and selling, 63c is a subtotal key, and 63d is a cash sales key.

FIG. 4 is a block diagram of the RAM 3 described above. Area M1 constitutes the ECR data area and includes a department aggregator that aggregates the sales amount for each department, an operator aggregator that aggregates the sales amount for each operator, and a function aggregation key that aggregates the sales amount for each function key. Composed of. Area M2 constitutes a numeric buffer BN. The data entered by the ten key 62 is temporarily stored in this buffer BN. area
M3 constitutes an extended time (PT) storage area. This extension time (PT) can be input and set from the ten-key pad 62 in the program mode. The set extension time is, for example, 2 hours when the business closing time is 2:00 am on the next day. Area M4 constitutes a work (W) area. Area M5 stores the current time.

Next, the operation of the ECR will be described with reference to FIG. The figure is a flow chart showing the schematic operation of the ECR.

First, in step n1, it is determined whether or not there is a key input (hereinafter, step ni is simply referred to as ni). It is judged whether it is due to 63d. If it is an input other than those keys, it moves to other processing. If it is a numeric keypad, then proceed from n2 to n5 to store the numeric data in the numeric buffer BN.
At n6, the numerical data is displayed on the display unit 4 and again n1
Return to. If the department key is entered, proceed from n3 to n7 to register the department. In order to register the department, normally, the sales amount is input with the ten keys 62, and then the department key 61 is operated. Therefore n3
If the process proceeds to → n7, the sales amount is stored in the number buffer BN, and then the department key 61 is operated. When the department registration is completed, the sales amount is displayed on the display unit 4 at n8, and the sales amount is printed on the receipt at n9. Also, n1
When the buffer BN is cleared at 0, the original n1 is returned.

When the cash sales key 63d is operated, the process proceeds from n4 to n11. Normally, when this key is operated, it is the end of the transaction. In n11, sales processing is performed. When the sales process is completed, it is determined in n12 whether the transaction is completed. If the transaction has not ended, the process returns to n1 again. Since the transaction is normally completed, proceed from n12 to n13. At n13, the value of the extension time PT stored in the area M3 is subtracted from the current time stored in the area M5. And if the result is negative, n14 to n15
Go to and set the registration date printed on the receipt to the previous day. If the result of subtraction is positive, the process proceeds from n14 to n16 and the registration date is set to the current date.

Due to the above operation, for example, a certain transaction will be held on March 15 at 23: 5
Suppose it was done at 0. Further, it is assumed that the extension time PT is set to 2 hours. In this case, subtracting the extension time of 2 hours from the current time of 23:50 results in 21:50. This value is positive. Therefore, the date printed on the receipt is March 15 which is the actual date (the current day). FIG. 5 (A) shows a printing example in this case. Next transaction is March
Suppose it was held at 0:10 on the 16th. In this case, subtracting the extension time of 2 hours from the current time of 0:10 gives -1: 50 (= 22: 10). This value is a negative value. Therefore, the date printed on the receipt will be March 15th, which is the day before March 16th of the actual date (current day). FIG. 5B shows an example of printing in this case.

As described above, it is possible not to update the registration date printed until the shop is closed even after midnight.
