2. Description of the Related Art Generally, electronic cash registers are equipped with a printer for printing receipts. When one customer completes the registration of the purchased product by inputting the closing key on the keyboard, a receipt is automatically issued on which sales information, total amount information, date information, etc. of the registered product are printed out.

[0003] Incidentally, some customers request the issuance of a receipt in which the date, total amount, issuer's name, recipient's name, etc. are written in addition to the receipt. For this reason, stores prepare receipt forms in advance with fields such as date, amount, issuer, and recipient fields, so that when a customer requests a receipt, the store clerk will issue a receipt. They wrote the date, total amount, recipient's name, etc. on a piece of paper and handed it to the customer.

0004

[Problems to be Solved by the Invention] Conventionally, store clerks had to write the date, total amount, recipient's name, etc. on a special receipt paper, which placed a heavy burden on the store clerk, and it was necessary to prepare a special receipt paper in advance. It was a hassle to prepare.

[0005] Therefore, the present invention makes it possible to automatically issue a receipt by printing the necessary items for a receipt on receipt paper, thereby reducing the burden on clerks required to issue receipts, and making it possible to prepare dedicated receipt paper in advance. The aim is to provide an electronic cash register that eliminates the need for cash registers.

[0006]

[Means for Solving the Problems] The present invention is provided with a printer for printing receipts, a date memory for storing dates, and a total amount memory for storing the total amount of products sold to one customer. Every time a sales product is registered, the sales amount of the registered product is added to the total amount memory, and when the closing key is input, the printer sends the sales information of the registered product, the total amount information in the total amount memory, and the date in the date memory. In an electronic cash register that issues a receipt with date information printed on it, a receipt key that instructs to issue a receipt with a date field, amount field, issuer field, recipient field, etc., and this receipt. Receipt data creation means for creating receipt print data in which the date information in the date memory and the total amount information in the total amount memory are set in the date field and amount field of the receipt, respectively, in response to a key input from a key;
The apparatus further includes a receipt issuance control means for operating a printer in accordance with the receipt print data created by the creation means to print and issue a receipt on receipt paper.

[0007]

[Operation] With the present invention having such a structure, the date memory stores the current date, and the total amount memory stores the total amount of money for the customer who is currently registering the product. In this state, when the user inputs the closing key to instruct the end of the customer's registration, the printer issues a receipt on which sales information, total price information, date information, etc. of the product purchased by the customer are printed. Also, when you key in the receipt key, the date field, amount field, issuer field, recipient field, etc. are formed, and the date field shows the date information in the date memory, and the amount field shows the total amount in the memory. A receipt on which amount information is printed is printed on receipt paper by the printer and issued.

FIG. 1 is a perspective view showing the external appearance of an electronic cash register, in which a keyboard 2 as an input section for registering sales products and a keyboard 2 as an input section for registering sales products, as well as a "registration" A mode switch 3 is provided to switch between various business modes such as ``Payment'', ``Settings'', etc.A display 4 is attached to the top surface for electronically displaying the price of registered products and the customer's total amount. A drawer 5 is installed for storing cash and the like. A printer 6 for printing a receipt is built into the housing 1, and a receipt printed by the printer 6 is issued from a receipt issuing port 7.

[0010] The keyboard 2 has various keys necessary for product registration, such as a number key, a department key, a subtotal key, and a closing key, as well as a date field 11, an amount field 12, and an issuer field as shown in FIG. A receipt key 2a is provided for instructing the issuance of a receipt 10 in which a column 13, a recipient column 14, etc. are formed.

FIG. 3 is a block diagram showing a control circuit of the electronic cash register. In the figure, reference numeral 21 denotes a main CPU (central processing unit) constituting the main body of the control unit, and a ROM (read-only memory) on the main body side in which program data etc. are stored is connected to this main CPU 21 via a bus line 22. ) 23, a main body side RAM (random access memory) 24 in which various memory areas used for data processing are formed, a clock circuit 25 that measures the current date and time, and a signal from the mode switch 3 is inputted. In addition, an I/O port 26 outputs an opening drive signal to the drawer 5, a display controller 27 controls driving the display 4 to display characters, etc. corresponding to display data, and corresponds to input keys from the keyboard 2. A keyboard controller 28 that takes in key signals, and a communication interface 2 that sends print data etc. to the printer 6.
9 etc. is connected.

Reference numeral 31 denotes a sub-CPU that controls the operation of the printer, and print data etc. from the printer-side ROM 33, printer-side RAM 34, and the communication interface 29 are sent to the sub-CPU 31 via the bus line 32. A communication interface 35, a character generator 36, and an I/O port 37 for receiving the data are connected.

The I/O port 37 includes a dot head 38 for printing dots on the receipt paper, a cutter 39 for cutting the receipt paper, a paper feed motor 40 for feeding the receipt paper, a carriage motor 41 for scanning the carriage, and an ink ribbon. A ribbon motor 42 and the like that sends the ribbon is connected.

In addition to the memory area for registering product sales data, the main body RAM 24 stores receipt data in which format data for printing the receipt 10 is set in advance, as shown in FIG. Memory 51, total amount memory 5 that stores the total amount of products sold to one customer
2. A date memory 53 for storing dates, a print data transmission buffer 54 for temporarily storing print data to be transmitted to the printer 6, etc. are formed.

Incidentally, in the format data set in the receipt data memory 51, the data corresponding to the date field and the data corresponding to the amount field 12 are rewritable, and the other parts are fixed. . Further, a store name, address, and telephone number are set in advance in a portion corresponding to the issuer name column 13.

As shown in FIG. 5, the printer-side RAM 34 includes a print data reception buffer 61 for temporarily storing received print data, an image buffer 62 for drawing dot images, and the like.

The main CPU 21 is programmed to read the date information measured by the clock circuit 25 at a predetermined timing and store it in the date memory 53.

Further, when a product for sale is registered by key input on the keyboard 2 while the mode switch 3 selects the "registration" mode, the main CPU 21 stores the sales amount of the registered product in the total amount memory 52. The content is added and the addition result is stored again in the same memory 52. At this time, the code and price (sales amount) of the registered product are displayed on the display 4, and a receipt is printed by the printer 6. Thereafter, the above process is repeated every time a sales product is registered, and when the closing key is input and the end of registration of sales products for one customer is declared, the contents of the total amount memory 52 are set as the customer's total amount. Display on display 4. Further, the program is controlled so that the printer 6 prints the total amount on a receipt and the receipt is issued from the receipt issuing port 7.

In addition, in response to the first product registration of one customer, the total amount memory 52 is cleared to "0", and
The date information in the date memory 53 is printed on the receipt by the printer 6.

Further, when the main CPU 21 detects the key input of the receipt key 2a after the input of the above-mentioned close key,
The program is set to execute the process shown in FIG. 6(a).

That is, after confirming that the closing key has been input, the format data stored in the receipt data memory 51 is transferred to the print data transmission buffer 54.
Set to . Next, the data corresponding to the date column of the format data is rewritten to the contents of the date memory 52 (current date), and the data corresponding to the amount column is rewritten to the contents of the total amount memory 52 (customer's total amount). Next, the contents of the transmission buffer 54, that is, the receipt data, are transmitted to the printer 6 via the communication interface 29. At this time, a command instructing 90 degree left rotation printing is added to the receipt data. Thereafter, a receipt issuing command is sent to the printer 6, and this process is completed. (Receipt data creation means)

On the other hand, the sub CPU 31 of the printer 6 receives the receipt data via the communication interface 35.
As shown in FIG. 6(b), first, the receive buffer 61
Read character data (ASCII code) from . Then, a dot image corresponding to this character data is called from the character generator 36 and developed in the image buffer 62. However, since a command to instruct 90 degree left rotation printing is added, the dot image is rotated 90 degrees counterclockwise before being developed. Thereafter, the same process is sequentially repeated for the character data of the received receipt data, and when all the data has been drawn, the contents of the image buffer 62 are printed on the receipt paper. After that, when a command to issue a receipt is received, the receipt feed is controlled and the cutter 39 is operated to cut the receipt paper, thereby creating a receipt 1 using the receipt paper.
0 is issued from the receipt issuing port 7. (Receipt issue control means)

In this embodiment configured as described above, the customer registers the products to be purchased by inputting the product registration key on the keyboard 2, and after registering all products, the customer inputs the closing key to complete the registration. When the end is declared, a receipt is issued from the receipt issuing port 7 by the action of the printer 6.

In this state, if the customer requests issuance of a receipt, the clerk inputs the receipt key 2a. Then, the format data of the receipt 10 preset in the receipt data memory 51 is set in the transmission buffer 54. Also, date column 11 of the above format data
The data corresponding to is rewritten to the current date information stored in the date memory 53, and the data corresponding to the amount column 12 is also rewritten to the total amount information of the customer stored in the total amount memory 52, Receipt data is created. This receipt data is then transmitted to the printer 6, and printed on a receipt paper by the action of the printer 6, thereby issuing a receipt 10 shown in FIG.

In FIG. 2, arrow A indicates the direction in which the receipt 10 is issued. In this embodiment, when sending the receipt data to the printer 6, a command instructing it to rotate 90 degrees to the left is added and sent, so the printed characters are rotated 90 degrees counterclockwise compared to the receipt. It will be printed. As a result, a horizontally long receipt 10 will be issued. The receipt 10, which has been issued with the necessary information printed on the receipt paper, is handed to the customer by the store clerk after writing only the recipient's name in the recipient column 14.

As described above, according to this embodiment, a desired receipt 10 can be printed and issued using receipt paper by a simple key operation of inputting the receipt key 2a. Therefore, the burden on the store clerk for issuing receipts is greatly reduced, and the effort of preparing dedicated receipt paper in advance is also eliminated, so excellent effects can be achieved both economically and in terms of goods management.

[0027] In the above embodiment, the receipt data contains 90
Although we have shown an example of issuing a landscape receipt 10 by adding a command to rotate counterclockwise, the format of the receipt is not particularly limited. For example, a portrait receipt may be issued without adding the above command. You may also do so. Further, it goes without saying that the items to be printed on the receipt are not particularly limited to the items in the above embodiment.

Furthermore, a receipt key may be used instead of the closing key, and the receipt 10 may be printed and issued instead of issuing a receipt. In this case, it is convenient to set the timing of printing the receipt so that it is printed all at once after key input.

In addition, it goes without saying that various modifications can be made without departing from the spirit of the invention, such as applying the invention to an electronic cash register that functions as a POS terminal.

[0030]

[Effects of the Invention] As detailed above, according to the present invention, a receipt can be automatically issued by printing the necessary items for a receipt on receipt paper, and the burden on store staff required to issue a receipt is greatly reduced. In addition, it is possible to provide an electronic cash register that eliminates the need to prepare a dedicated receipt paper in advance, improves economic efficiency, and simplifies article management.
