After being transferred to the section 23, the bit image data is transferred to the clerk side display section control section 23 continuously for one block. As a result, the store clerk side display unit control unit 23 sequentially writes the bit image data to the address VADS of the internal VRAM (video random access memory) designated by the CPU 14, and then periodically outputs the bit image data from the VRAM. The information is read out and displayed on the clerk side display unit 10.

Next, the operation of the first embodiment of the above-described checkout device will be described with reference to the flowchart of FIG. When the checkout device is powered on, the CPU 14 first performs initialization processing such as initialization of each I / O port, flag register of the RAM 16, product registration buffer, and clearing of customer purchase total area.

Next, in order to settle the products purchased by the customer, when the ECR in the first embodiment is reached, the operator registers the individual products purchased by the customer. Here, as an example, the customer is one apple, four lemons,
The following description will be made assuming that one pear is purchased and the operator registers those products in the ECR in the first embodiment in the order of apple → lemon → lemon → lemon → pear → lemon.

First, in step SA1, the operator registers a product (apple). At this time, there are the following three registration methods. The bar code reading surface 9a of the scanner 9 is made to read the code data corresponding to the bar code attached to or printed on the product. If the product data regarding the apple is set in the preset key, the preset key of the second operation unit 13 is pressed. The amount of money and the department code of the product to be registered are input from the first operation unit 6 or the second operation unit 13.

Further, the CPU 14 performs the following processing "" corresponding to the above-mentioned registration method. 'The PLU code is transferred from the read code data to the master, and the product data corresponding to the PLU code is received from the master. 'Product data corresponding to the pressed preset key,
It is read from the preset key file in the RAM 16. 'Set the department data corresponding to the entered department code to R
The product data is read from the department file in the AM 16. Further, the CPU 14 accumulates the product data read by any of the above-mentioned methods in the total customer purchase area in the RAM map of FIG. 3, and proceeds to step SA2.

Next, in step SA2, the CPU 14
Searches the empty column from the top in the product registration buffer in the RAM map shown in FIG. 3, and based on the product data (here, apple product data) read in step SA1, the product registration data, that is, the item A number (or a department number if a department is registered), a quantity, an amount, a unit price obtained by dividing the amount by the quantity, a product name (the same department name), etc. are written in the corresponding columns in FIG. Further, the CPU 14 displays a preset key and a product name column and a price column of the product on the salesclerk side display unit 10 to display a product registration screen (not shown), and then displays the product name and selling price of the product on the salesclerk side display unit. 10 and the second customer side display unit 11.

Next, in step SA3, it is determined whether or not the product registration for one customer has been completed and the operator has pressed the closing key. This judgment result is No,
Return to step SA1. Hereinafter, the processes of steps SA1, SA2, and SA3 are repeated until the lemon is finally registered. Here, in step SA2, the RAM of FIG.
In the product registration buffer in the map, as shown in FIG. 4, the product registration data of the products registered from the top is written in the order registered in step SA1.

When the operator registers the last lemon and presses the close key in step SA1, the CPU1
4. After accumulating the product registration data for the lemon in the customer purchase total area, the process proceeds to step SA2 and step S2.
After writing the product registration data for the product (lemon) registered in A1 in the corresponding columns at the bottom as shown in FIG. 4, the process proceeds to step SA3.

Next, at step SA3, the judgment result is Y.
It becomes es, and proceeds to step SA4. Step SA4
Then, various total data such as the total purchase amount and the number of purchased products accumulated in the total customer purchase area in the RAM 16 are accumulated in the total file as store data, and closing processing such as clearing the total customer purchase area is performed. Further, the maximum value MAX of the product designation values of the read pointer and the comparison pointer is set. That is, a value obtained by subtracting 1 from the number of product registration data written in step SA3 (here, 6-
1 = 5) is the maximum value MAX. After this, step SA
Go to 5.

Next, in step SA5, the CPU 14
Reads out the product registration data designated by the read pointer from the individual product registration data stored in the product registration buffer shown in FIG. Here, since the product specification value of the read pointer is 0 in the initial state, the read pointer specifies the product registration data registered at the beginning of the product registration buffer (that is, product registration data regarding apples). Therefore, the CPU 14 reads the product registration data regarding the apple. Further, the CPU 14 sets the product designation value of the comparison pointer to the same value as the product designation value of the read pointer (that is, 0), and then proceeds to step SA6.

Next, at step SA6, 1 is added to the product designation value of the comparison pointer, and the comparison pointer designates the product registration data in the product registration buffer according to the product designation value. Here, the product designation value of the comparison pointer is determined in step S.
1 is added to 0 set in A5 to become 1 and the product registration data registered in the next stage of the product registration data registered at the top of the product registration buffer (ie, lemon product registration data) is designated. , Step SA7.

Next, in step SA7, step S
In A5, the item number and unit price of the product registration data designated by the read pointer and the product registration data designated by the comparison pointer are compared with each other. Here, the apple item number is 222222, the unit price is 150 yen, the lemon item number is 111111, and the unit price is 100 yen, so the comparison result is No, and the process proceeds to step SA9.

Next, at step SA9, it is determined whether or not the comparison pointer has designated all the product registration data in the product registration buffer, that is, whether or not the product specification value of the comparison pointer has reached the maximum value MAX (= 5). To judge. Here, the product designation value of the comparison pointer is 1 and the maximum value MAX is 5.
Therefore, the determination result is No, and the process returns to step SA6.
Next, in step SA6, 1 is set to the product designation value of the comparison pointer.
2 is added, and the comparison pointer designates the product registration data of the lemon in the third row from the top in FIG. 4, and proceeds to step SA7.

Next, in step SA7, the item number and unit price of apples are compared with the item number and unit price of lemons in the third row from the top in FIG. 4, but only one apple is registered after all. The comparison result is No, and the process proceeds to step SA9. Hereinafter, steps SA6 and S are performed until the product designation value of the comparison pointer reaches the maximum value MAX.
The processing of A7 and SA9 is repeated.

In step SA6, the product designated value of the comparison pointer becomes equal to the maximum value MAX (= 5), and then in step SA7, the apple item number and unit price and the pear item number and unit price in the last row in FIG. When the comparison result of No is No and the process further proceeds to step SA9, the determination result is Y in step SA9.
es, and the process proceeds to step SA10.

Next, in step SA10, the CPU 1
4 is the product registration data designated by the read pointer
The product name (in this case, apple) and the price (150 yen in the same case) are transferred as print data to the printer control unit 20 together with a print command. Further, the printer control unit 20 drives the printer 7 to print on the receipt paper. (Fig. 9
(See (b), 1st line) When the product registration data designated by the read pointer does not exist, that is, when the print data is 0, the CPU 14
Does not transfer the print command to the printer control unit 20, so that the print is not performed on the receipt paper. After printing, the product designation value of the comparison pointer is cleared, and the process proceeds to step SA11.

Next, in step SA11, it is determined whether or not the read pointer has finished pointing to all the product registration data in the product registration buffer, that is, whether or not the product designated value of the read pointer has reached the maximum value MAX (= 5). To judge. Since the product designation value of the read pointer is 0, the judgment result is N.
Then, the operation proceeds to step SA12.

Next, at step SA12, 1 is added to the product designation value of the read pointer, and the next stage of the product registration buffer (see FIG. 4).
The product registration data of the second lemon from the top is designated in the product registration buffer (1), and the process proceeds to step SA5. Next, in step SA5, the CPU 14 reads the merchandise item registration data designated by the read pointer, sets the merchandise item designation value of the comparison pointer to the same value as the merchandise item designation value of the read pointer (that is, 1), and then proceeds to step SA6. . Next, in step SA6, 1 is added to the product designation value of the comparison pointer, so that the product designation value of the comparison pointer becomes 2. Therefore, the comparison pointer is shown in FIG.
In the product registration buffer of, the product registration data of the lemon in the third row from the top is designated, and step SA7 is performed.
Go to.

Next, in step SA7, step S
In A5, the item number and unit price of the product registration data designated by the read pointer and the product registration data designated by the comparison pointer are compared with each other. Here, since the item numbers and unit prices of both are the same, the comparison result is Yes, and the process proceeds to step SA8. Next, at step SA8,
The CPU 14 adds the quantity and price of the product registration data designated by the comparison pointer to the quantity and price designated by the read pointer, respectively. After this addition, the CPU 14 clears the stage of the product registration data designated by the comparison pointer (that is, the lemon product registration data in the third line from the top in FIG. 4), and then proceeds to step SA9.

Next, in step SA9, it is determined whether or not the product designation value of the comparison pointer has reached the maximum value MAX. Here, since the product designation value of the comparison pointer is 2, the determination result is No and the process returns to step SA6. Hereinafter, steps SA6, SA7, SA8 (only when the same product is searched) and SA9 are repeated until the product designation value of the comparison pointer reaches the maximum value MAX. And
When the product designation value of the comparison pointer becomes the same value as the maximum value MAX and the processing of steps SA7 and SA8 has been completed,
The product registration data regarding lemons is in a state where the quantity and the amount of money are totaled.

When the process proceeds from this state to step SA9, the determination result in step SA9 becomes Yes, and the process proceeds to step SA10. Next, in step SA10, C
The PU 14 selects the product name (in this case, "lemon") and the amount ("4 yen" in the product registration data designated by the read pointer).
00 ”), unit price (100 yen for the same) and quantity (“ × ”for the same)
"4""is transferred as print data to the printer controller 20 together with the print command, and the printer 7 is driven to print on the receipt paper. (See the second and third lines in FIG. 9B) After printing, the product designation value of the comparison pointer is set to 0, and the process proceeds to step SA11.

Next, in step SA11, it is determined whether or not the product designation value of the read pointer has reached the maximum value MAX (= 5), and the determination result is No, so step SA1
Proceed to 2. After that, the CPU 14 performs processing in accordance with the above-described processing procedure. For example, when the product registration data whose read pointer has already been cleared is read, step SA
After performing a series of processing from 6 to SA9, step SA
Since the print data becomes 0 in 10, the CPU 14 does not transfer the print command to the printer control unit 20, and the print is not performed on the receipt paper.

The read pointer product designation value is the maximum value MAX.
(= 5), and when the comparison of all the product registration data registered in the product registration buffer shown in FIG. 4 is completed, the receipt printed as a result has the content shown in FIG. 9B. Then, when the determination result in step SA11 is Yes, the process proceeds to step SA13. Next, in step SA13, the operator cuts the printed receipt and hands it to the customer. Next, in step SA14, C
The PU 14 clears the product designation values of the product registration buffer, the read pointer, and the comparison pointer, respectively, and the checkout process for one customer is completed.

As described above, according to the first embodiment of the present invention, in the conventional ECR, the receipt is printed as shown in FIG. 9A, but the receipt is printed in FIG. 9B. Since the receipt is printed as shown, the number of lines printed on the receipt can be reduced.

Next, a second embodiment of the present invention will be described. The configuration of the second embodiment is similar to that of the first embodiment, and only the processing operation is partially different. Therefore, the checkout device shown in FIGS. 1 and 2 is also applied to the second embodiment. Therefore, the names and reference numerals of the respective parts in the second embodiment are the same as those in the first embodiment.

The operation of the second embodiment will be described below with reference to FIG. First, when the power of the checkout device is turned on, the CPU 14 performs the same initialization processing as that of the first embodiment, and the operator checks the individual products purchased by the customer for the ECR in the second embodiment. Register. Here, the customer has one apple and four lemons as in the first embodiment.
It is assumed that one piece and one piece are purchased, and that the operator registers these products in the ECR in the second embodiment in the order of apple → lemon → lemon → lemon → pear → lemon.

First, in step SB1, the operator registers a product (apple) in the ECR in the second embodiment. At this time, the registration method of the merchandise by the operator and the registration processing of the CPU 14 for the registration method are the same as steps SA1 and SA2 in FIG. Next, at step SB2, the CPU 14 obtains at step SB1 the item number and unit price of the merchandise registration data that the comparison pointer sequentially designates from the top to the bottom in the merchandise registration buffer shown in FIG. The item number and unit price of the product data are compared, and product registration data having the same item number and unit price are searched. When the search is completed, the process proceeds to step SB3.

Next, at step SB3, the CPU 14
As a result of the search performed in step SB2, it is determined whether the same item number and unit price are registered. Here, since there is no registered product registration data yet, the determination result is No, and the process proceeds to step SB5. Next, in step SB5, the CPU 14 writes the product registration data of the product (in this case, an apple) registered in step SB1 in the empty top row of the product registration buffer shown in FIG. 4, and proceeds to step SB6.

Next, in step SB6, the CPU 14
Determines whether the operator has pressed the close key.
Here, since the operator has not completed registration of all the products purchased by the customer, the tightening key is not pressed. Therefore, the determination result is No, and the process returns to step SB1. In step SB1, the operator registers the first lemon, and then in step SB2, the CPU 14
Searches for item registration data having the same item number and unit price as the item data and unit price of the item data regarding lemon while comparing from the uppermost stage of the item registration buffer one by one. When the search is completed, the process proceeds to step SB3.

Next, in step SB3, the CPU 14
Determines whether the same item number and unit price are registered as a result of the search performed in step SB2. Here, since only the product registration data of apples is registered in the product registration buffer, the determination result is No.
Then, the process proceeds to step SB5. Next, in step SB5, the CPU 14 writes the product registration data of the product (lemon in this case) registered in step SB1 to the empty top stage of the product registration buffer, that is, the next stage of the apple product registration data, Go to SB6.

Then, in step SB6, the determination result is No, and the process returns to step SB1. Next step SB
In 1, the operator registers a second lemon, and then in step SB2, the CPU 14 stores the item number and unit price of the product data of lemon and the product registration data having the same item number and unit price in the product registration buffer. The search is performed while comparing the uppermost one by one, and when the search is completed, the process proceeds to step SB3. Next, in step SB3, since the product registration data of lemon already exists in the product registration buffer, the determination result is Yes, and the process proceeds to step SB4.

Next, in step SB4, step S
The quantity and price of the product (lemon in this case) registered in B1 are added to the quantity and price fields of the same product registration data searched in step SB2, and the process proceeds to step SB6. In step SB6, the determination result is No, and the process returns to step SB1. Thereafter, in step SB1, the CPU 14 steps SB1 → SB2 → S until the operator registers all the products purchased by the customer and presses the closing key.
The processing is performed in the order of B3 → SB4 (or SB5) → SB6.

Next, when the operator registers the last lemon in step SB1 and presses the tightening key, step S1 is executed.
In B2, the CPU 14 searches the product registration buffer for the product registration data having the same item number and unit price as the item number and unit price of the last registered lemon. At this time, as the product registration data in the product registration buffer, as shown in FIG. 5, product registration data for one apple, three lemons, and one pear is registered in the registration buffer. Next, in step SB3, the determination result is Y
When it becomes es, the CPU 14 performs the processing of step SB4, and adds the quantity and the amount of the lemon registered last to the quantity and the amount in the commodity registration data of the lemon shown in FIG. 5, and as a result, as shown in FIG. , The quantity in the product registration data of lemon is "4", and the amount is "400".

Next, the process proceeds to step SB6 and step SB
In step 6, since the tightening key is pressed in step SB1, the determination result is Yes, and the process proceeds to step SB7. Then, in step SB7, step S of FIG.
After performing the tightening process similar to A4, the process proceeds to step SB8.

Next, in step SB8, the read pointer sequentially designates one step from the top of the commodity registration buffer shown in FIG. 6, and the CPU 14 reads out the commodity registration data designated by the read pointer and designates the designated commodity registration data. Among them, the product name and the amount of money (the unit price and the quantity of the product having the same product such as lemon are also included) are used as print data, and are transferred to the printer control unit 20 together with the print command. The printer control unit 20 drives the printer 7, and
The contents shown in (b) are printed on the receipt paper.

Next, in step SB9, the operator cuts the printed receipt and hands it to the customer. Next, in step SB10, the CPU 14 clears the product designation values of the product registration buffer, the read pointer, and the comparison pointer. This completes the checkout process for one customer.

As described above, according to the second embodiment of the present invention, in the conventional ECR, the receipt is printed as shown in FIG. 9A, but the receipt is printed in FIG. 9B.
