Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a bar code scanner or an OCR (character reading device) for optically reading a single product code attached to a product.
The present invention relates to a merchandise sales data processing device.

[Prior Art] Conventionally, there is a single product file in which product information such as product name and unit price is set and stored corresponding to the single product code of each product, and a single product code attached to each product, for example, as a bar code is fixed. A product sales data processing device that reads with a bar code scanner such as a scanner or a hand scanner, performs a search for the single product file based on the read single product code, reads the corresponding product information, and executes the sales registration process,
It is widely used in POS (Point of Sale Information Management) systems and two-person electronic cash registers. In addition, recently, there is also one in which a single item code is displayed as it is without being bar-coded, and this number is directly read by an OCR to perform a sales registration process.

As described above, in the product sales data processing device provided with the code reader for reading the single product code attached to the product, for example, when the read single product code is not set in the single product file, an error occurs, and the error state is Until it is canceled, registration of the product including the product in error will not be performed. Therefore, when an error occurs, an error sound is generated from the code reader or the keyboard to alert the operator. However, when the store is busy, the operator may continue to read the code of the product without noticing the error sound. When such an operation error occurs, the display of the error state is only repeated on the display unit, and even if the operator notices the error display and operates the error release key, the display unit displays the initial display (for example, “0 It was difficult because it was necessary to inspect the journal to check which product the error occurred by simply switching to "Display only".

[Problems to be Solved by the Invention] As described above, in the conventional merchandise sales data processing apparatus of this kind, the code reading of the merchandise is continued without noticing that an error has occurred in the code read by the code reader. In that case, it is difficult to confirm which product caused the error when the error release operation was performed, and it takes time to check the journal, etc. And
There was a risk of registration errors such as missing registration and double registration.

Therefore, the present invention determines which product the error occurred by performing the error canceling operation even if the code read by the code reader does not notice that an error has occurred and the code reading of the product is continued. An object of the present invention is to provide a product sales data processing device that can be easily confirmed and can prevent registration errors such as missing registration and double registration as much as possible.

[Means for Solving the Problem] The present invention is provided with a code reader for reading a single product code attached to a product, and product sales data for performing sales registration processing of the product based on the single product code read by the code reader. In the processing device, the code reading is performed by the code reader in a state where the error determination means determines whether or not there is an error in sales registration based on the product code read by the code reader, the buffer, and the error determination means. When the error cancel key is operated while the error judgment means judges that there is an error, the buffer storage processing means for accumulating and storing the unregistered data in the buffer, the error cancel key for canceling the error state, Unregistered that counts the number of accumulated unregistered data and outputs the count value as unregistered points And a score output means.

[Operation] In the product sales data processing device having such means, when an error occurs in sales registration based on the product code read by the code reader, data indicating that the code is read by the code reader is displayed. It is stored in the buffer as unregistered data. Thereafter, each time the code is read by the code reader without operating the error cancel key, the unregistered data is accumulated and stored in the buffer. Then, when the error cancel key is operated, the number of unregistered data accumulated in the buffer is counted, and the counted value is output as the unregistered point. Therefore, the operator can confirm that an error has occurred in the product registered earlier by the number of unregistered points that were output, and by re-registering from this product, it is possible to securely register sales without missing registration or double registration. Can be processed.

[Embodiment] An embodiment in which the present invention is applied to a POS system will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram of a POS system, which includes a plurality of POS terminals 1 for registering sales of each product and each POS.
A POS controller 2 that collects sales data of products registered at the terminal 1 and issues a report or the like is connected inline in a closed loop by a transmission line 3.

It said POS controller 2 includes a control unit 2 ₁ for controlling the operation of each unit according to a program, a transmission interface 2 ₂ for controlling the data transfer is performed between the POS terminal 1 through the transmission line 3, each product separately code of the product corresponding unit price, a memory unit 2 ₃ separately file is formed for setting storing the product information of product name, etc., and a printer 2 ₄ for printing and sales reports.

FIG. 2 is a block diagram of the POS terminal 1.
In the figure, reference numeral 11 denotes a CPU (central processing unit) as a control unit main body, which incorporates an arithmetic circuit, a memory control circuit, and the like,
A ROM 12 that stores fixed data such as programs for executing various operations while performing various calculation processes based on input data, and a registration process for the sales amount and sales points of the registered products for sale RA with memory
Control M13 and. In addition, the clock circuit 1 that measures the current time
4, a transmission interface 15 for controlling data transmission with the POS controller 2, an I / O port 17 for inputting a signal from a mode switch 16 for selecting each business mode such as "registration", "payment" and "setting" A keyboard input circuit 19 for inputting and processing a key signal from the keyboard 18, a display control circuit 21 for driving and controlling the display unit 20, a printer drive circuit 23 for a printer 22 for printing receipts and journals, and a cash storage device. The I / O port 26 that outputs a drive signal to the drawer opening device 25 of the drawer 24, the I / O port 28 that inputs a signal from the stationary scanner 27 for reading the bar code attached to the product, and the like, It is connected to CPU11.

As shown in FIG. 3, "00" is displayed on the keyboard 18.
In addition to the numeral keys 31 of "0" to "9", various function keys such as a subtotal key 32, a current total key 33, a multiplication key 34 and a clear key 35 are provided. The clear key 35 functions as an error cancel key for canceling the error state.

The display unit 20 is composed of a 2 × 16 character dot display and an LED (light emitting diode) for indicating various states such as “registering” and “transmitting”. The product name, unit price, number of items sold, amount sold, total amount, deposit amount, change amount, etc. are displayed on the display.

In the RAM 13, for example, a sales registration file for totaling the sales points and sales prices of registered products for each department, and a totalizer for adding up the sales prices of the products sold to one customer to calculate the total price, etc. In addition to the sales registration memory, as shown in FIG. 4, an application key buffer (hereinafter abbreviated as APL key buffer) 40 for storing data related to various inputs for product registration for one customer is formed. There is.

Then, the CPU 11 is controlled by the program in the ROM 12 so as to execute the processing shown in the flowchart of FIG. 5 in the state where the "registration" mode is selected by the mode switch 16. That is, when an operation of reading a barcode by the stationary scanner 27 is performed as ST (step) 1, so-called scanning is performed, the read barcode is converted into a single item code, and the inquiry message of the item information by the single item code is edited. And inquires to the POS controller 2 via the transmission line 3. Then, the POS controller 2 searches for separately file of the memory unit 2 ₃ it is determined whether it is done commodity information corresponding to the single item code, in the case of there product information consists of the product information response Denbun Is returned to the POS terminal 1 that made the inquiry, and if there is no product information, a response message consisting of error information is returned to the POS terminal 1 that made the inquiry. Then, whether or not an error has occurred is judged from the response message (error judgment means), and if there is no error, the normal registration processing is executed as ST4. That is, the unit price of the returned product information is set as the sales amount, and the sales point is set as "1", and is cumulatively registered in the sales registration file in the RAM 13. Also, the sales amount is added to the totalizer in the RAM 13. Further, the product name and the sales amount are displayed on the dot display unit of the display unit 20, and the printer 22 prints out the receipt and the journal. Then, in ST5, the hard key code (eg, “26”, 03 ”) normally registered and the length data (“ 01 ”in the above example) indicating the data length of this key code are registered data as the APL key buffer. Sequentially stored in 40,
Wait for the next input.

On the other hand, if an error occurs in ST3, use RAM1 as ST6.
Set a scanning error flag (hereinafter abbreviated as an error flag) preset in 3 to "1", and as ST7, scan a hard key code (for example, "F6") and read bar code data (for example, 12
34567890123456 ") and length data (" 09 "in the above example) indicating these data lengths are stored in the APL key buffer 40 as unregistered data, and the next input is awaited.

Then, in this error state, when scanning is performed again in ST1, the error flag is set to "1" in ST2, so the process moves to ST7, and unregistered data in the same format as above is written to the APL key buffer. The data is sequentially stored in 40 (buffer storage processing means) and waits for the next input.

On the other hand, in the error state, if there is key data input from the keyboard 18 as ST8 and that key data is due to the clear key 35 as ST9, the hard key code (for example, "3E") by the clear key input as ST11 Length data indicating the data length of this key code (“01” in the above example) is stored in the APL key buffer 40. Next, as ST12, the number of scanning hard key codes stored in the APL key buffer 40 is counted. Then, as ST13, the counted value is displayed on the dot display of the display unit 20 as an unregistered point output means. At this time, for example, as shown in FIG. 6, a message “Mitokurokutensu” is displayed on the upper stage of the dot display and the unregistered points (eg “03”) are displayed on the lower stage.
Is displayed. After that, if the error flag is reset to "0" in ST14, wait for the next input.

In the present embodiment configured as described above, the cashier operating the POS terminal 1 sequentially reads the barcodes attached to the products purchased by the customer with the stationary scanner 27. Then, the registration processing of the product is performed based on the read bar code, and the registered data (data at the addresses “k” and “k + 1” in FIG. 4) is stored in the APL key buffer 40. Here, if an error occurs in the registration process,
The error flag is set to "1" and unregistered data (data at address "k + 2" in FIG. 4) is stored in the key buffer 40. At this time, an error sound is emitted from the stationary scanner 27 or the keyboard 18 to call attention to the cashier, but if the cashier does not notice the error sound and scans the products one after another, the sales registration of those products will be made. Is not executed and APL key buffer 4
Unregistered data in 0 (address “k + 3” in FIG. 4 “k +
4 ”data) is stored.

For example, when the cashier recognizes that the cashier is in the error state after scanning two items after the error occurs, the cashier presses the clear key 35 to cancel the error state. Then, the number of the hard key code “F6” by scanning stored in the APL key buffer 40 is counted, and the number “3” is displayed as the unregistered point on the dot display of the display unit 20 as shown in FIG. Is displayed.

Therefore, the cashier can easily recognize that an error has occurred during the scanning of the product 3 points before by this unregistered mark display, and by re-registering from the product 3 points before, registration error such as missing registration or double registration can be made. It is possible to reliably register all products of one customer without violating.

As described above, according to the present embodiment, even when the cashier does not notice the error when a scanning error occurs and some products are continuously scanned, the clear key 35 is input to perform the error releasing operation. Since the score of the unregistered product including the error product is displayed and output, the cashier can easily confirm the error product. As a result, the registration can always be surely performed again from the product in which an error has occurred, so that it is possible to prevent registration errors such as missing registration and double registration. Further, since it is not necessary to check the journal to confirm the product in which an error has occurred, product registration can be resumed in a short time, and there is no risk of waiting the customer.

In addition, in the above-mentioned embodiment, the single item code is converted into a bar code,
Although the POS terminal 1 that reads it by the stationary scanner 27 is illustrated, it goes without saying that the present invention can be applied to a POS terminal in which a single-piece code is represented by a number and is read by OCR. Further, in the above embodiment, the case where the present invention is applied to the POS system is shown, but it is needless to say that the present invention can be applied to a single electronic cash register or a two-person electronic cash register.

[Effects of the Invention] As described in detail above, according to the present invention, even if the code reading of the product is continued without noticing that the code read by the code reader has caused an error, the error canceling operation is performed. By performing the above, it is possible to easily confirm in which product the error has occurred, and it is possible to provide a product sales data processing device capable of preventing registration errors such as missing registration and double registration as much as possible.
