Abstract

PURPOSE:To print successively the contents of a buffer memory and to issue a receipt in response to a request of a purchaser, by providing an issue commanding circuit which generates a receipt issue command signal with operation of a receipt issue key. CONSTITUTION:A receipt issue stop switch is turned on, and the input numerical value and department signals are converted into codes by a decoding circuit and supplied to an arithmetic control circuit. The arithmetic control circuit feeds the unit price of articles to a print data circuit 8-4 via a unit price register 8-1. The circuit 8-4 produces a print data to be transferred to a print buffer in accordance with the contents of the register 8-1 and a sales total register 8-2 as well as the key information. An address signal producing circuit 8-3 uses a decoder signal as an input and produces an address signal of a buffer memory for issue print. In other words, this address signal is reset when a transaction is started and increased successively every time an item is registered.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic register capable of issuing receipts.

A normal electronic register is equipped with a printer for business records and a printer for issuing receipts, and when registering large items purchased, it prints business records and receipts at the same time, and can be used as receipts and sales records. It is configured to be used for

However, in small-scale stores, etc., product purchasers often do not request receipts, so the electronic register is used to record receipts with the receipt issuance function stopped using the receipt issuing switch in the electronic register. We are trying to use less paper. If a purchaser requests a receipt after registering a purchased large item in an electronic register, the electronic register will not be able to issue a receipt as the receipt is registered with the receipt issuing function disabled. Since it is not possible to do so, the contents of business records are copied in writing to create receipts.

The present invention aims to provide an electronic register that eliminates such problems, and even when registration is performed in the receipt issuing stop mode by selecting a switch, the content to be printed on the receipt is automatically changed. The contents of the buffer memory are written to the receipt print buffer memory, and when the receipt issue key is operated in response to a receipt request from the product purchaser, the contents of the buffer memory are printed in sequence, allowing the receipt to be issued. It is something.

Next, the present invention will be explained along with one embodiment thereof. In Figure 1, 1 is a numeric key, usually 0°1,...
- 10 pieces are provided corresponding to each numerical value of 9. Reference numeral 2 denotes a department key, which is shown as one in the figure, but is provided as many as the product departments, and registers the departments of sales products. 3 is a total key which, when operated after registering each product, calculates and prints the total amount.

4 is a receipt issuing key that is a feature of this embodiment. 6 is a receipt issue stop switch, and when this switch is operated, the printing of the receipt, which is normally printed at the same time as the printing of business records, is stopped.

6 is a decoder circuit that converts the signal of each key into a code, TE is an inverter, and 8 is an arithmetic control circuit that operates according to instructions from the decoder circuit 6. Reference numeral 9 is a print buffer for business records, and 10 is a print buffer for printing receipts.These buffers 9 and 10 have a capacity of one line, where the number of print lines is 7. Reference numeral 11 denotes a print buffer for printing receipts, which has a capacity for 24 lines. 13 is an AND circuit, and 14 is an OR circuit.

FIG. 2 shows the detailed configuration of the arithmetic control circuit 8, in which 8-1 is a register for registering the unit price, 8-2 is a register for registering the sales total, and 8-3 is an address signal for the buffer memory 11. Address signal creation circuit for creating 8-4
8-6 is a print data circuit that creates print data, and 8-6 is a circuit that generates a receipt issue command.

Next, the operation of this embodiment will be explained. For example, if you turn on the receipt issue stop switch 6 and sell a product worth 100 yen, use number key 1 to enter the number 100 representing the amount, and use department key 2 to enter the department of the product. input. The nine input numerical division signals are each code-converted by a decoder circuit 6 and input to an arithmetic control circuit 8.

In the arithmetic control circuit 8, the product unit price is stored in the unit price register 8-
1 and enters the print data circuit 8-4. It is still added to the sales total register 8-2 in sequence.

The print data circuit 8-4 includes a unit price register, a star 8-1, a sales proceeds register 8-2. Then, based on the key information, which is a decoder signal, print data to be transferred to the print buffer is formed. Further, the address signal generation circuit 8-3 receives the decoder signal and generates an address signal for the buffer memory 11 for printing a receipt. In other words, this address signal is reset at the start of one transaction, and incremented sequentially each time one item is registered.With the above operation, the arithmetic control circuit 8 inputs the unit price and department data into the print data. The circuit 8-4 outputs one line of print data to the business record print buffer 9, receipt print buffer 10.11.The output of the print buffer 9 is input to the business record printer 16, and the business record is It will be printed.

Since the output of the print buffer 10 is closed by the inverter output of the signal from the receipt issue stop switch 5, the AND circuit 12 cannot be input to the printer 16 for printing receipts. Therefore, printing on receipts is prohibited, and only business records are printed.

The print buffers 9 and 10 each have a capacity for printing one line, while the print buffer 11 has a capacity for 24 lines, as shown in FIG.

11-1 to 11-24 each represent one line of printing); indicate rough/register, and buffers of 20 lines from 11-1 to 11-20 are used to store print data when registering individual products. The buffers for four lines 11-21 to 11-24 are used as storage 7 for transaction data generated at the end of a transaction, such as the total amount and change.

Next, a method of storing data in the print buffer 11 will be explained.

Since the number 100 just registered is the first item in this transaction, the output of the address signal generation circuit 8-3 is 1.
becomes. Therefore, the buffer register 11-1 of the buffer memory 11 is selected and stored therein.

Next, assume that you have registered a product that costs 200 yen. By the same operation as above, the numerical value 200 is printed on the business record along with the department data. Since the address signal is still incremented by one and becomes 2 by this item, the buffer register 11-2 is selected and stored there.

Next, if you operate G1G 3 to end this transaction, the contents of "Sales Tips" register 8-2 will be the total amount.
It is created by the print data circuit 8-4, passes through the business record print buffer 9, and is printed by the business record printer 16. At the same time, it is also stored in the print buffer 11, but this -
In this case, the address signal generation circuit 8-3 instructs 21 based on the key information of the gold side key 3, and the print data of the total amount is stored in the buffer register 11-21.

With the above operation, the registration of one transaction mentioned as an example has been completed, but in this case, the receipt issuance stop switch 5
Since the registration was made while operating the transaction, no receipt was issued, and the transaction data was printed only on the business record.

Here, when the product purchaser requests a receipt, the receipt issuing key 4 is operated. The signal from the receipt issue key 4 is input to the arithmetic control circuit 8 via the decoder circuit 6. The arithmetic control circuit 8 stores key information and sales quotation register 8.
A receipt issuing command signal is generated by the receipt issuing command circuit 8-5 based on the signal from -2 (this signal is used as status information indicating that the position/allocation key 3 has been operated).

The receipt issuing command signal opens the AND circuit 13, and the address signal generating circuit 8-3 sequentially outputs address signals 1 to 24, so the contents of the print buffer 11 are sequentially transferred to the receipt printing printer 16. Issue a receipt.

Note that for buffer registers that have not been written to in the print buffer 11, their output is transferred to the printer 16 as 0, but the transferred data for one line is all 0.
In this case, since a printer that is not recognized as print data is used, there is no need to worry about blank feeding of the recording paper in the receipt printing printer 16.

Furthermore, when the next transaction starts, new print data starts to be written into the print buffer 11 as buffer data for receipt printing at the same time as printing on the business record. In this case, as the address signal is reset at the same time as the start of the transaction, the address signal generation circuit 8-3 generates a buffer reset signal, resets all the contents of the print buffer 11, and prints the print data of the previous transaction and the trade transaction. This prevents data from being mixed in the contents of the print buffer 11.

As explained in the above embodiment, according to the present invention, even if the issuance of normal receipts is stopped, a receipt with detailed contents recorded can be issued in response to a request from a product purchaser.
It is possible to provide an electronic register that saves recording paper and also has the function of issuing receipts.
