Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention makes it easier to see the cancellation of the printed sales data when the sales data of one product is printed out over multiple lines on a receipt. Regarding registers.

[Prior Art] Generally, in an electronic cash register, when a cashier inputs sales data such as a department code of each product sold to a customer or a product code and a sales amount with an input device such as a keyboard or a bar code scanner, the cashier inputs each time. The sales data of the product is registered in the storage unit, displayed on the display unit, and printed out on the receipt. And
After the registration process for all the products sold to customers,
When the cashier performs a closing key operation such as a deposit / cash total key, the total amount of money is displayed and the receipt is printed out and a receipt is issued.

In such an electronic cash register, if the cashier makes a mistake in key operation when entering each sales data,
If an error is noticed before the input operation of the sales data for the next product is started, the sales data registered immediately before can be canceled only by the key input operation of the cancel key of the keyboard. In this case, when the cancel key is keyed in, the registration in the storage unit is canceled, and a cancellation line consisting of a dashed line indicating cancellation is displayed on the sales data such as the department code or product code printed on the receipt or the sales amount. Overprinted.

By printing the cancellation line over the canceled sales data in this way, the customer can immediately check the receipt and immediately confirm which product has been canceled.

[Problems to be Solved by the Invention] However, even in the electronic cash register in which a cancellation line such as a broken line is overprinted on the sales data to be canceled as described above, the following problems still to be improved was there. That is, in recent years, in the case of printing out a product code or product name with a large number of digits instead of a department code in an electronic cash register, or simultaneously printing out a discount rate or a discount amount for a discounted symmetrical product, Since the receipt width has a certain limit, sales data for one product is printed out on two or more lines on the receipt. When deleting sales data printed over multiple lines in this way, unless the printed output receipt is fed in reverse, a strikethrough line is overlaid on the last line of the printed sales data. It is only output.

Therefore, there is a problem that the customer cannot immediately determine how many lines of the sales data printed on the receipt have been canceled.

The present invention has been made based on such a situation, and its purpose is to trace back the sales data printed out on the receipt to the last line printed out when canceling the line backwards. An object of the present invention is to provide an electronic cash register in which a customer can immediately confirm canceled sales data by looking at a receipt by printing a number of cancellation symbols corresponding to the number of lines to be canceled.

[Means for Solving Problems] According to the present invention, the sales data of each sales product input via the input device is registered in the storage unit each time it is input, and at least one line is stored as a receipt. In the electronic cash register that prints out, every time the sales data of each sale product is printed out on the receipt, the printed line counter that counts the number of lines printed on the receipt, and the cancellation to cancel the sales data registered immediately before A key and a means for canceling the sales data registered immediately before from the storage section when the cancel key is entered, and a means for subtracting 1 from the print line number counter when the cancel key is entered. If the count value of the subtraction result print line counter by this means is 1 or more, a cancel symbol of the number corresponding to the count value of the print line counter is present at the current print position. A print canceling means is provided for performing overprinting and for overprinting the strikethrough line.

[Operation] In the electronic cash register configured as described above, when an input error is noticed when the input operation of the sales data for one product is completed, if the cancel key is operated by key operation, the sales data input immediately before is displayed in plural lines. When the printout has been completed, the number of cancellation symbols and the strikethrough lines corresponding to the number of print lines to be canceled retroactively are overprinted on the last line of the printout completed. Therefore, the customer can immediately check the receipt and immediately know to which line the cancellation was made.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a perspective view showing an electronic cash register of the embodiment. As shown in the drawing, the electronic cash register is provided with a keyboard 2 as an input device on the front surface of the housing 1 and at the top of the housing 1. Is equipped with a display unit 3 for electronically displaying the product code, department code, sales amount, total amount, etc. of the sold products, and a receipt issuing port 4 and a cash drawer 5 for storing cash in the middle and lower parts, respectively. There is. Further, a customer display unit 6 having the same structure as the display unit 3 is attached to the upper surface of the housing 1.

As shown in FIG. 3, the keyboard 2 calculates a JAN code of a product to be sold, a sales key, a sales key, a department key 8 for indicating a product classification, and a total price. In addition to keys for sales registration such as deposit / cash total key 9 as a closing key, a JAN key 10 used when entering the JAN code of a product to be sold, and two types of keys used to sell the product at a discount A% discount key 11, a cancel key 12 for canceling the sales data registered immediately before, a control key 13 operated by the key, and the like are provided.

The control key 13 is a control switch for performing on / off control of the power supply and for instructing the central processing unit to execute various tasks such as [registration] and [settlement]. [Registration] is a task of registering a department code or a product code of a sold product, a sales amount, a sales quantity, etc. in a storage unit, calculating a total amount, etc., and printing the result on a receipt. Further, “payment” is a job for printing out the total sales registered in the storage unit at the end of the day's job.

FIG. 1 is a block diagram of an electronic cash register. The CPU (central processing unit) 14 has a built-in arithmetic circuit and the like, performs various arithmetic results based on the input information from the keyboard 2, and also performs the above-mentioned operations via the address bus 15, data bus 16 and control line 17. ROM 18 for storing fixed data such as programs and RAM 19 for storing sales data such as sales amount of each product keyed in
And operate. Further, a control key input circuit 20 to which a command signal from the control key 13 is input, a keyboard input circuit 21 to which a key signal from the keyboard 2 is input, a display control circuit 22 for sending a display signal to the display units 3 and 6, A printer control circuit 24 of a dot printer 23 that prints out sales data and the like on a receipt is connected to the CPU 14 via a data bus 16 and a control line 17, respectively.

As shown in FIG. 4, the RAM 19 stores a unit price of each sale item and a sales registration file R1 for accumulatively registering the number of items sold and the amount of sale for each item code, the total number of items sold to one customer. Totalizer R2 for calculating the amount of money
A display buffer R3 for temporarily storing display data to be displayed on each of the display units 3 and 6, a print buffer R4 for temporarily storing print data to be printed out on a receipt, and sales data corresponding to one product keyed from the keyboard 2 ( Count the number of print lines N on the receipt of the product code, department code, sales amount, discount amount, etc.) Print line number counter R5
Further, a discount rate memory R6 and the like for storing two types of discount rates corresponding to the respective% discount keys 11 are formed.

Then, the power of the device is turned on, and the control key 1
3 is set to the [registration] business mode, the CPU
14 is configured to execute the sales registration business according to the flowchart of FIG. That is, when the main routine is started, it waits for key information input by the key input operation of the keyboard 2. When the key information is input, the type of the key information is checked. Then, at P1, the key information is the numeric key 7, JAN key 10 or department key 8
If it is key information for merchandise registration by key operation such as, the input JAN code and the unit price read from the sales registration file R1 of the RAM 19 are displayed on the display units 3 and 6 via the display buffer R3 and are also displayed on the print buffer R4. Store. Then, the count value N of the print line number counter R5 is reset to 0, and at P2, a command is sent to the dot printer 23 through the printer control circuit 24 to feed the receipt by one line. Then, of the sales data such as the JAN code and the sales amount (unit price) stored in the print buffer R4, the data corresponding to one line of the receipt is printed out on the receipt by the dot printer 23. Then, the count value N of the print line number counter R5 is incremented by one. Then, it is checked whether or not there is sales data that has not been printed out on the receipt in the print buffer R4, and if it exists, the process returns to P2 and the receipt is fed by one line, and the remaining sales data is printed out. Then, when the print output processing of all the sales data in the print buffer R4 is completed, a predetermined registration processing is executed. That is, the sales amount is added to the totalizer R2.
And the sales number and sales amount of the corresponding product code (JAN code) in the sales registration file R1 are updated. When the registration process for one product is completed, the process returns to the beginning of the flowchart and waits for the next key input operation.

If the key information entered in P3 is for the cancel key 12, it is determined that the cancellation process of the sales data registered immediately before has started, and the count value N indicating the number of print lines of the print line number counter R5 of the RAM 19 is reached. Read out. Then, 1 is subtracted from the count value N. Next, the upward arrows as N cancellation symbols corresponding to the number N of lines after subtraction and one broken line as a cancellation line are stored in the print buffer R4. And
The arrow and the broken line stored in the print buffer R4 are superposed on one line of the receipt and printed without feeding the paper. Therefore, the number of cancellation signals and cancellation lines corresponding to the number of lines to be canceled retroactively are superimposed and printed on the last line of the sales data of the product registered immediately before.

It should be noted that if the count value N of the print line number counter R5 is 1, N = 0 is obtained by subtraction, so that the arrow is not printed and only the broken line is overprinted and output.

When the overprinting process of the cancellation signal and the cancellation line is completed, the cancellation process of the corresponding sales data in the totalizer R2 and the sales registration file R1 is performed.

Further, if the key information entered at P4 is a closing key such as the deposit / cash total key 9, the total amount of the totalizer R2 is displayed on the display units 3 and 6, and normal total registration such as change calculation is performed. After the processing is performed, the receipt is fed by one line and the total amount and the amount of change are printed out. Then cut the receipt,
It is discharged from the receipt issuing port 4.

In the electronic cash register configured in this way, RA
When a discount rate of 10% is set in the discount rate memory R6 of M19 corresponding to the% discount key 11 of I, J
FIG. 6 shows the key operation procedure and the receipt print format when the registration is canceled immediately after the product with the AN code [7] is registered at a 10% discount. That is, as shown in the figure, the numeral key 7 of [7], JAN key 10,% of I
If you enter the discount key 11 continuously, the receipt 25
The sales data is printed out on three lines. That is, a message indicating that the registration is made with the JAN code is printed on the first line, the JAN code of [7] and the sales amount (unit price) [¥ 150] are printed on the second line, and the final line is printed. Indicates a discount message [discount], discount rate [10
%] And the discount amount [15] are printed out.

Then, when the cancel key 12 is keyed in, two upward arrows indicating the number of lines to be deleted backward and a broken line are overprinted on the last line.

Further, FIG. 7 shows the key operation procedure and the receipt 2 when canceling the product of 100 yen of department code [3] immediately after registration.
5 shows a print format of No. 5. That is, when the sales amount [100] and the department key 8 of [3] are continuously key-operated with the numeric keypad 7, [003
One line of sales data of [¥ 100] is printed out. Then, when the cancel key 12 is keyed in, a broken line indicating cancellation is overprinted on one line of sales data.

When canceling sales data printed over multiple lines in this way, a cancellation line consisting of a broken line is overprinted on the last line of the sales data, and the number of cancellation symbols corresponds to the number of lines to be traced back. Is printed over the last line, the customer can later see the receipt 25 and immediately know which sales data has been canceled.

In addition, since the dot printer 23 generally prints out the same contents as the receipt 25 on a journal (internal recording paper), the cashier can also use the canceled sales data when confirming the contents printed on the journal at the time of settlement work. You can grasp it accurately.

[Effects of the Invention] As described above, according to the present invention, when the printed output sales data on the receipt is to be deleted backward, the number corresponding to the number of lines to be deleted backward to the last printed output line. The cancellation symbol of is overprinted. Therefore, since the customer can confirm the canceled sales data immediately by looking at the receipt later, the service to the customer can be improved.
