Next, the operation of this embodiment will be described. First, the transaction processing executed by the CPU 2 will be described with reference to FIG.
This will be described based on the flowchart shown in FIG.

In FIG. 11, the CPU 21 first determines whether or not product data has been input from the input device 22 (step S1). If the product data has been input, the input of the product data is performed in the current transaction. It is determined whether the input is the first input (step S2). If the merchandise data is the first input, the store name / message data stored in advance in the store name / message data memory 23a in the RAM 23 (see FIG. 6) is stored in the RAM 2 as shown in FIG.
3 in the temporary storage memory 23f (step S3).
3) The input product data is registered (update of product data and subtotal calculation) (step S4), and the product data is displayed on the display device 24 (step S5). As shown in FIG. 8, the information is stored in the temporary storage memory 23f (step S6), and the process returns to step S1.

In step S2, if the input of the product data is not the first input in the current transaction,
The CPU 21 proceeds to step S4, and repeatedly executes a registration process, a display process, and a temporary storage process for each of the product data input thereafter.

If the product data is not input in step S1, the CPU 21 determines whether or not "close" is input (step S7). If the "close" is input, the close process (total / change) (Step S8), the closing data is displayed on the display device 24 (Step S9), and stored in the temporary storage memory 23f as shown in FIG. 7 (Step S10).
A journal print process is executed (step S11).

In this embodiment, the receipt 21 and the journal are simultaneously sent and printed by one printing mechanism in the thermal printer 7 shown in FIG.
The receipt / journal printing process is executed based on the flowchart shown in FIG.

In FIG. 12, the CPU 21 reads out the store name / message data which is the first data stored in the temporary storage memory 23f by the transaction processing (step S101), and sets the print position memory 23h in the RAM 23.
A print format (receipt data printing per line) based on print digit data previously stored in the print digit number memory 23i in the RAM 23 in accordance with each paper width of the receipt roll paper and the journal roll paper based on the setting flag in Receipt print data is created in the print buffer memory 23e according to the number of digits, the number of journal print digits, and the number of blank digits (step S102).

Next, the CPU 21 determines whether or not the read shop name / message data is a transaction item that requires journal printing, based on the print items shown in FIG. 8 previously stored in the print item memory 23g in the RAM 23 (see FIG. 8). Step S103). In the print item memory 23g shown in FIG. 8, merchandise data, tax data, and total data are set as print items for the journal, so the store name and message data are unnecessary as print items for the journal.

In this case, the CPU 21 inserts a blank in the journal print digit portion following the receipt print data created in the print buffer memory 23e by the print format (step S104), and creates the print buffer memory 23e. Based on the received receipt print data and blank data, the image of the receipt print data corresponding to the print dots of the thermal head in the thermal printer 7 shown in FIG. 1 is developed in the work memory 23j. , The first one line is latched (step S106), and the thermal printer 7

Next, the CPU 21 confirms whether or not printing of all lines of the receipt print image developed this time has been completed (step S108).
The receipt print image for the next one line is latched (step S109), and the process returns to step S107 to print the next latched one line until step S107 is completed until it is confirmed that the printing of all the lines of the store name / message has been completed. ~
The process of step S109 is repeatedly executed.

Then, the CPU 21 stores the temporary storage memory 2
It is confirmed whether or not all printing of the current transaction data stored in 3f has been completed (step S110), and if not completed, the product data “PLU1 ramen” which is the transaction data next to the store name and message shown in FIG. "¥ 100" is read (step S111), and the process returns to step S102.
According to the print format, the print buffer memory 2
The next receipt print data is created in 3e.

Next, the CPU 21 determines whether or not the product data is a transaction item that requires journal printing, based on the journal print items stored in the print item memory 23g of FIG. 8 (step S103). Since the item data is set as the item, the journal print data corresponding to the journal print digit portion following the receipt print data created in the print buffer memory 23e in the print format is created in the print buffer memory 23e. (Step S105), the work memory 23 is stored in the print buffer memory 23e using the receipt print data and the journal print data.
The receipt print data and the journal print data corresponding to the print dots of the thermal head are developed in j, and the first one line of the receipt print image and the journal print image is latched (step S1). S106), the receipt roll paper 15 and the journal roll paper 16 while driving and controlling one system of the printing mechanism and the spool mechanism in the thermal printer 7 shown in FIG.
The first one line of the product data "PLU1 ramen ¥ 100" is printed (step S107).

Then, the CPU 21 proceeds to step S107.
The processing from step S109 to the product data "PLU1
The process is repeatedly executed until the printing of all the lines of "Ramen ¥ 100" is confirmed, and it is confirmed whether or not all the printing of the current transaction data stored in the temporary storage memory 23f has been completed (step S110). For example, the product data “PLU2 juice” which is the transaction data following the product data “PLU1 ramen ¥ 100” shown in FIG.
"200" is read out (step S111), and the process returns to step S102 again to execute steps S102 to S1.
09 is repeatedly executed, and the product data “PLU2
The creation processing and the printing processing of the receipt print data and the journal print data of "Juice ¥ 200" are repeated.

Thereafter, the CPU 21 repeatedly executes the receipt / journal printing process for the other transaction data of this time similarly stored in the temporary storage memory 23f of FIG. 7, and in step S110, stores all of the current transaction data stored in the temporary storage memory 23f. When the end of transaction data printing is confirmed, FIG.
The process returns to step S1.
