Abstract

PURPOSE:To prevent unnecessary subtotal printing from being executed, to make a receipt easily visible, and also to avoid waste of forms by resetting a flag of a storage device except the case when printing which does not exert influence on a subtotal amount is executed by a processing device. CONSTITUTION:An ROM2, an RAM3, a keyboard 4, a display device 5, a printer 6 and a cash drawer 7 are connected to a processor 1 as functioning a control device of an ECR. A registering key 21, a department key 23, a subtotal key 24, a non-AND key 25 and a mode changeover switch 26, etc. are provided on this keyboard 4. In this state, in case when printing which does not exert influence on a subtotal amount of the RAM3 is executed by the processor 1, a flag is not reset, and in case other printing is executed, the flag is reset, by which it is prevented that an unnecessary subtotal printing is executed, a receipt is made easily visible, and waste of forms is avoided.

Description

[Detailed Description of the Invention] (Field of the Invention) The present invention relates to an electronic cash register, and in particular, to prevent printing of a subtotal amount, etc., performed multiple times for the same subtotal amount in response to pressing a subtotal key. Regarding electronic cash registers.

(Background of the Invention) In the conventional electronic cash register G1, when the subtotal key is pressed, the subtotal amount, etc. is printed, that is, the subtotal is printed, but if the subtotal key is pressed multiple times in succession, the same amount is printed. To avoid printing subtotals multiple times in succession, set a flag indicating that a subtotal has been printed when a subtotal is printed, and reset this flag when something other than a subtotal is printed. was. 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 a flag indicating that subtotal printing has been performed is set, printing that does not affect the subtotal amount, such as a customer number or slip number, that is, printing called N0NADD, is performed. Since the flag is also reset, if the subtotal is printed once and then N0NADD is printed, the flag is reset, and when the subtotal key is pressed thereafter, the subtotal is printed again, which is an inconvenience. In other words, in this case, the subtotal amount printed first is the same as the subtotal amount printed next, and there is no need to print the subtotal a second time; there is an inconvenience that the subtotal is printed even though it is the same. Ta.

(Object of the Invention) The object of the present invention is to provide an electronic cash register where, after one subtotal is printed, even if the next N0NAD
The purpose is to prevent the same subtotal from being printed again even if D printing or the like is performed.

(Structure and Effects of the Invention) The present invention provides an electronic cash register system that prevents subtotal printing even if the subtotal key is pressed when a flag indicating that subtotal printing has been performed is set. This is based on the concept of not resetting the flag if printing that does not affect the subtotal amount is done, and it is possible to prevent unnecessary subtotal printing (this !/Receipts become easier to read and waste of receipt paper can be avoided.

(Example of the invention) Hereinafter, the present invention will be explained in detail 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, processor 1 has a read-only memory (ROM).
2, random access memory (RAM) 3, and various input/output devices 2 are connected. The input/output devices connected to the processor 1 include a keyboard 94, a display 5 including a numeric display, a printer 6 for printing receipts, and a cash register 7 for storing cash for transactions. etc. are connected.

FIG. 2 shows the arrangement of keys on the keyboard 4 in the device shown in FIG. 1. That is, the keyboard 94 of the device shown in FIG. 1 includes a number key 21 including a clear key CL, a department key 22 for inputting the department code of a transaction product, a total key 23, a subtotal key 24, a non-atto key 25, etc. Equipped with various keys.

Further, a mode changeover switch 26 for changing over the operating mode 9 of the electronic cash register is provided. In the above-mentioned electronic cash register, when making a product transaction, etc., the price of the transaction product, the department code, etc. are input in sequence using the number key 21 and the department key 22, etc., and when all items have been input, The subtotal key 24 is pressed.As a result, the subtotal amount and some symbol or character indicating that the amount is a subtotal are printed.

When such a subtotal is printed, a subtotal print flag FC8 provided in the random access memory 3 (FIG. 1) is activated.
Even if TPT is set and the subtotal key is subsequently pressed, the subtotal will not be printed if this flag is set. The subtotal print flag FC8TPT is reset when printing something other than the subtotal, for example, when the numeric key 21 and department key 22 are pressed, and when the subtotal key is pressed thereafter, the subtotal is printed. becomes possible. However, after the subtotal print flags FCS and TPT are set, the flags will not be reset even if printing that does not affect the subtotal amount, such as non-atto key 25, is performed.
Therefore, the subtotal cannot be printed continuously. Non-attribute printing is used, for example, when printing a customer number or slip number on a receipt. Printing is performed by inputting the customer number, etc. with the numeric keys 21 and then pressing the non-attribute printing - 25 button. However, the subtotal amount is not affected.

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. In the case of a numeric key, manual processing of the numeric key is performed, such as sequentially storing numeric data corresponding to the pressed key in a predetermined storage unit. 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. , then subtotal print flag FC8T
Determine whether PT is 1''.

If the flag is set to 1''', it means that the previous printing or the latest printing other than non-attributes is a subtotal printing, so the process ends without printing a subtotal.If Subtotal print flag FC3TPT
If is reset to °゛0''', the previous print is a non-attribute or something other than a subtotal, so the printer prints the subtotal amount and characters indicating that the amount is a subtotal on the receipt. Print the subtotal.

Then, a flag FC8 indicating that subtotal printing has been performed.
Set TPT to '1'' and end the process. If the pressed key is a non-at key, the display will indicate that the non-at 9 key has been pressed, and the printer will display a non-at key on the receipt. In this case, the subtotal print flag FC3TPT is not changed in any way, and therefore the state before non-attribute printing is maintained, so the subtotal will be printed next depending on whether or not the subtotal was printed before non-attribute printing. Printing control is performed when a key is pressed.If a key other than the subtotal and non-at key is pressed, the subtotal print flag FC8TPT is reset, so the next time the subtotal key is pressed, the subtotal is printed. will be carried out. For example, when a department key is pressed as a key other than the subtotal key and the non-ato key, as shown in FIG. Print this. Next, set the subtotal print flag FC8TPT to
IOII, that is, reset, and processes other than display and printing, such as memory update, are performed, and then the post-processing is completed.
