Description

DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to an electronic cash register that limits the issuance of receipts depending on the type of product and the number of transactions.

(Background of the Invention) With the recent decline in the price of semiconductor IC devices, a large amount of random access memory has come to be used in electronic cash registers (hereinafter simply referred to as ECR), and The operation has been simplified by registering names and amounts. In addition, in the future, it will be necessary to comprehensively monitor and manage sales and inventory of all products through transaction registration with ECR.

For this reason, in the conventional ECH, a transaction registration operation is performed for all products, and receipts are issued for all products even when registering low-priced products or when receipts do not need to be issued. As a result, unnecessary receipts are issued, consumables such as printing paper and ink are wasted, and maintenance costs for printers and the like are increased.

(Object of the invention) The object of the present invention is to solve the problems of the conventional type described above.
To reduce the waste of consumables such as printing paper and ink and to reduce printer maintenance costs by restricting the issuance of receipts in ECR according to the department items and the number of traded products.

(Structure and Effects of the Invention) The present invention allows ECR to determine whether or not to restrict receipt issuance, and when restricting receipt issuance, to determine whether or not to restrict receipt issuance for each department item at the time of presetting. When registering a transaction, it is determined whether or not receipt issuance is restricted for each product item, and the number of transactions for the items for which receipt issuance is restricted is compared with the preset upper limit number of items for which no receipt is to be issued. This determines whether or not it will be issued.

In the present invention, by using such a configuration, it is possible to prevent the issuance of unnecessary receipts and reduce the cost of consumables such as printing paper and ink, and the maintenance cost of the printer.

Regarding the receipt issue restriction items, when a receipt is issued, a subtotal is printed, so it is possible to check the amount by looking at the receipt later.

(Example of the invention) Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows the appearance of an ECR according to one embodiment of the present invention. The ECR shown in the figure is composed of a keyboard 1, a display 2, a printer 3, and the like.

FIG. 2 shows a detailed configuration of the keyboard 1 of the ECR shown in FIG. The keyboard shown in the figure is equipped with a numeric keypad or numeric key 4 including numeric keys, a correction key, a clear key, etc., a product category key 5 that can each register product names and unit prices, a subtotal key 7, and a total key 8. . Further, the keyboard 9 is provided with a mode switch 9, and the EC
It is possible to set a setting mode for presetting R, a registration mode for transaction processing, and various other modes.

FIG. 3 shows the circuit configuration of the ECH shown in FIG.

The circuit shown in the figure includes a CPU 10 constituted by a microcomputer or the like, a read-only memory 11, a random access memory 12, and the aforementioned keyboard 1, display 2, and printer 3. The read-only memory 11 stores ECH processing programs, etc.
The random access memory 12 stores various flags, counters,
It includes various data, storage areas, work areas, etc.

To explain each area of the random access memory 12 in detail, as shown in FIG. 3, FN is a flag indicating that the numeric key on the keyboard 1 has been pressed, and
is an area that stores the value of the pressed department key, RGTEN
is an area that stores values entered using the number keys. RGAMT is a work register for storing amount data, RGNUM is an area for storing the number of registered products, and ITE
M is a register for calculating the payment amount. RCPUB is a flag indicating whether there is a restriction on receipt issuance and is set at the time of presetting. If this flag is °゛0''', a receipt will be issued unconditionally, and if it is u1u, receipt issuance will be restricted.In addition, PUBCNT is an area that stores the upper limit number of items that do not require a receipt. For example, a value from 0 to 99 is set at the time of presetting.FRC
T is a flag indicating whether a receipt is required, ETAMT is an area for storing the subtotal of items that do not require a receipt, and ETCNT is a counter for counting the number of items that do not require a receipt. DIAMT is an area for storing the amount of department 1, and DIPUB is a flag indicating whether or not to restrict receipt issuing for department 1. Both of these are set at the time of presetting. Note that when the flag DIPUB is 0'', a receipt is issued unconditionally, and when it is 1lxl'', receipt issuance is restricted. D2AMT, D, 2PUB,
..., D20AMT, and D20PUB are for storing amounts and flags indicating whether or not to restrict receipt issuing for each department from department 2 to department 20, respectively, and have the same contents as for department 1. ing.

Next, with reference to FIGS. 4, 5, and 6,
Registration and print processing in CH will be explained. The process shown in FIG. 4 is performed with the mode switch 9 set to the registered mode 9. As shown in the figure, when there is any type of key input, processing is performed according to the type of key. If a numeric key is pressed, the number corresponding to the key is entered in the numeric register, and the flag FN is set to 1''.If a department key is pressed, the flag FN is set to 1''.
The presence or absence of numeric data is determined by N.

If there is data, that is, if the flag FN is "1", the contents of the number register are set in the amount register.

If there is no numerical data, that is, the flag FN is °0.
'', a preset amount corresponding to the pressed department key is set in the amount register.

In either case, after the product price is displayed, the registration process shown in FIG.
P is cleared and we wait for the next key power. When the total key, that is, the deposit/cash key is pressed, the payment amount is displayed, then the payment amount, etc. is printed as shown in Figure 6, and the payment stored in the payment amount calculation register is displayed. The values of the amount, flag FN, number register, amount register, and department key are all cleared to wait for the next key input. When a key other than the keys mentioned above is pressed, processing corresponding to each key is performed, but a description of these processing will be omitted.

FIG. 5 shows the procedure for printing registered data. In the process shown in the figure, first, it is determined based on the value of the flag RCPUB whether there is a restriction on receipt issuance. If it is necessary to restrict receipt issuance, it is determined whether the item is a receipt issuance restriction item based on the value of the flag DnPUB corresponding to the pressed department key number n. If the item is a receipt issue restriction item, the counter and amount of the receipt issue restriction item are updated. That is, counter ETCN
The contents of area RGNUM are added to the contents of T, and the contents of register RGAMT are added to the contents of area ETAMT. Next, the contents of the counter ETCNT are set to the area PUB
It is determined whether the content is greater than or equal to the content of CNT. If counter E
If the value of TCNT is smaller than the content of area PUBCNT, it is determined that there is no need to issue a receipt, and the payment amount is updated with the current registered amount, that is, the content of register RGAMT is added to the content of register ITEM, and the process ends. If the value of the counter ETCNT is larger than the content value of the area PUBCNT, it is determined that it is necessary to issue a receipt, and after setting the content of the flag FRCT to ``1'', the number of products indicated by the counter ETCNT and the area ETAMT are calculated.
Print the amount stored in the counter, and print the amount stored in the counter ET.
Clear CNT and area ETAMT. and,
The current registered amount stored in the work register RGAMT is added to the contents of the register ITEM to update the payment amount, and the process ends. Additionally, in the above process, if there is no receipt issue restriction or the pressed department key does not correspond to the receipt issue restriction item,
After setting the flag FRCT to °゛1'' and printing the product amount stored in the work register RGAMT,
The payment amount stored in the register IT'EM is updated with the current registered amount and processing is performed.

FIG. 6 shows a processing procedure in a payment amount printing processing routine used in the processing of FIG. 4. In the process shown in FIG. 6, first, it is determined based on the flag FRCT whether or not a receipt is required. If the flag F'RCT is n 1 u and it is necessary to issue a receipt, the counter ET
The value of CNT is determined. If the value of the counter ETCNT is greater than 0, the number of products indicated by the counter ETCNT and the amount of money stored in the area ETAMT are printed, and furthermore, the payment amount stored in the register ITEM is printed. If the value of the counter ETCNT is less than θ, only the payment amount stored in the register ITEM is printed.

After the above processing, counter ETCN'T, subtotal area E
TAMT and flag FRCT' are cleared and the process ends. In addition, in the initial judgment, the flag FRCT
If is '0''', each counter, area, etc. are cleared and the process is ended without printing.

Next, receipt printing processing will be specifically explained using a restaurant as an example. For example, the settings at the time of presetting shall be made under the following conditions.
