Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic cash register;
In particular, the present invention relates to an electronic cash register that prevents the same subtotal amount from being printed multiple times in response to pressing a subtotal key.

(Background of the Invention) In conventional electronic cash registers, when the subtotal key is pressed, the subtotal amount is printed, that is, the subtotal is printed, but when the subtotal key is pressed multiple times in succession, the subtotal of the same amount is printed. In order to avoid printing multiple times in succession, a flag indicating that a subtotal was printed was set when a subtotal was printed, and this flag was reset when a subtotal was printed. . When the subtotal key is pressed, this flag is checked, and if the flag is set, the subtotal is not printed, and if the flag is not set, the subtotal is printed.

However, in the conventional type, after the graph indicating that the subtotal has been printed is set, printing that does not affect the subtotal amount, such as a customer number or slip number, that is, printing called NONADD, is performed. Since the flag is also reset, there was an inconvenience that if the subtotal was printed once and then NONADD was printed, the flag was reset, and if the subtotal key was pressed afterwards, the subtotal was printed again. . In other words, in this case, the subtotal amount printed first is the same as the subtotal amount printed next, and there was an inconvenience that the second subtotal was printed even though it was unnecessary. .

(Object of the Invention) The object of the present invention is to provide an electronic cash register in which, after one subtotal is printed, even if the next subtotal is
The purpose is to prevent the same subtotal from being printed again even if NONADD printing or the like is performed.

(Structure, operation, and effect of the invention) In order to achieve the above object, the present invention includes a storage device that stores a flag indicating that subtotal printing has been performed, and a storage device that stores a flag indicating that subtotal printing has been performed, and when the flag is set, a subtotal key is pressed. In the electronic cash register, the processing device has a processing device that controls the printing of the subtotal so that the subtotal amount is not printed even if , and if the determining means determines that the pressed key does not affect the subtotal amount, the flag is not reset, and the determining means determines that the pressed key does not affect the subtotal amount. The system is equipped with a reset means for resetting the flag in the event of a failure.

In this configuration, if the subtotal key is pressed and the subtotal is printed while the flag is not set, the flag is set, but if any key is pressed after that, the pressed key will not affect the subtotal amount. If not given, the flag will not be reset, and if the pressed key affects the subtotal amount, the flag will be reset, so only when a key that affects the subtotal amount is pressed, will the subsequent subtotal key presses The subtotal will be printed.

Therefore, unnecessary printing of the same subtotal is prevented, the receipt becomes easier to see, and waste of receipt paper can be avoided.

(Embodiments of the invention) Hereinafter, embodiments of the invention will be described with reference to the drawings.
FIG. 1 shows the hardware configuration of an electronic cash register according to one embodiment of the present invention. In the configuration shown in the figure, a read only memory (ROM) 2, a random access memory (RAM) 3, and various input/output devices are connected to a processor 1. The input/output devices connected to the processor 1 include a keyboard 4, a display 5 including a numeric display, a printer 6 for printing receipts, and a cash drawer 7 for storing cash for transactions. is connected.

FIG. 2 shows the keyboard 4 in the device shown in FIG.
The key arrangement etc. above are shown. In other words, the keyboard 4 of the device shown in FIG. Comes with a key. A mode changeover switch 26 is also provided for changing over the operating mode of the electronic cash register. In the above-mentioned electronic cash register, when making a product transaction, etc., the price of the transaction product, the department code, etc. are entered in sequence using the numeric key 21 and the department key 22, etc., and when all items have been input, The subtotal key 24 is pressed.
As a result, a subtotal amount and some symbol or character indicating that the amount is a subtotal are printed. When such a subtotal is printed, the subtotal print flag FCSTPT provided in the random access memory 3 (Fig. 1) is set, and even if the subtotal key is pressed continuously thereafter, if this flag is set, the subtotal will not be printed. Printing is not performed. Subtotal print flag
FCSTPT is used when printing other than subtotals.
For example, when the numeric key 21 and the department key 22 are pressed, they are reset, and then when the subtotal key is pressed, it becomes possible to print the subtotal. However, after the subtotal print flag FCSTPT is set, even if printing that does not affect the subtotal amount, such as non-add key 25, is performed, the flag will not be reset, and therefore, it will not be possible to print the subtotal continuously. has been done. Non-ad printing is used, for example, when printing a customer number, slip number, etc. on a receipt. Printing is performed by inputting the customer number, etc. using the number keys 21 and then pressing the non-ad key 25. This is done so that it does not affect the subtotal amount.

FIG. 3 shows the procedure of processing performed when each key is pressed in the above-mentioned electronic cash register. In the figure, when any key is pressed, it is first determined whether the pressed key is a numeric key. If it's a numeric key,
A numeric key input process such as sequentially storing numeric data corresponding to the pressed key in a predetermined storage section is performed. If the pressed key is not a numeric key, it is determined whether or not it is a subtotal key, and if it is a subtotal key, first the subtotal amount and characters indicating that the amount is a subtotal are displayed on the display. , Next, it is determined whether the subtotal print flag FCSTPT is "1". If the flag is set to "1", it means that the previous printing or the latest printing other than non-ad is subtotal printing.
Ends the process without printing the subtotal. If the subtotal print flag FCSTPT is reset to "0", the previous print is a non-ad or something other than a subtotal, so the printer will indicate on the receipt the subtotal amount and that the amount is a subtotal. Print characters, etc. and print the subtotal. Then, the flag FCSTPT indicating that the subtotal has been printed is set to "1" and the process is terminated. If the pressed key is a non-ad key, the display unit displays that the non-ad key has been pressed, and the printer displays the non-ad key on the receipt, and the post-processing ends. In this case, the subtotal print flag FCSTPT is not changed in any way, and therefore the state before non-ad printing is maintained, so whether the subtotal key is pressed next depends on whether subtotal printing was performed before non-ad printing. Printing control is performed when the If a key other than the subtotal and non-add keys is pressed, the subtotal print flag FCSTPT is reset, so that the next time the subtotal key is pressed, the subtotal will be printed. For example, if a department key is pressed as a key other than the subtotal key and non-add key, as shown in Figure 3, the display will first indicate that the key has been pressed, and then the printer will and print it on the receipt. Next, set the subtotal flag FCSTPT to “0”
In other words, it is reset, and the post-processing is completed after processing other than display and printing, such as memory updating.
