Incidentally, the format data set in the receipt data memory 51 is such that the data corresponding to the date column and the data corresponding to the amount column 12 can be rewritten, and the other portions are fixed. . In the part corresponding to the issuer name column 13, a store name, an address, and a telephone number are set in advance.

As shown in FIG. 5, the printer side RAM 34 is provided with a print data receiving buffer 61 for temporarily storing received print data, an image buffer 62 for drawing a dot image, and the like.

Therefore, 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 the sale item is registered by the key input of the keyboard 2 while the "registration" mode is selected by the mode switch 3, the main CPU 21 stores the sale amount of the registered item in the total amount memory 52. The contents are added and the addition result is stored again in the same memory 52. At this time, the display unit 4 displays the code and price (sales amount) of the registered product.
And receipt printing is performed by the printer 6. After that, the above processing is repeated every time the merchandise is registered, and when the closing key is inputted and the end of the registration of the merchandise of one customer is declared, the total amount memory 52 is displayed.
Is displayed on the display 4 as the total price of the customer. The printer 6 is program-controlled so that the total amount is printed as a receipt and a receipt is issued from a receipt issuing port 7.

The total amount memory 52 is cleared to "0" in response to the first product registration of one customer (total amount memory clear means), and the date information in the date memory 53 is printed by the printer 6 as a receipt. It is supposed to be done.

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

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 (total amount of customers). Next, the contents of the transmission buffer 54, that is, the receipt data is transmitted to the printer 6 via the communication interface 29. At this time, a command for instructing 90 ° counterclockwise printing is added to the receipt data. After that, the receipt issue command is transmitted to the printer 6, and this processing is ended. (Receipt data creation means)

On the other hand, the sub CPU 31 of the printer 6 which has received the receipt data via the communication interface 35.
First, as shown in (b) of FIG.
