Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a product sales data processing device that can register product sales data by reading barcodes attached to products.

[Prior Art] 1. Barcodes attached to products include product codes, amount codes, check codes, etc., but there are also barcodes that do not have deposit codes. Conventionally, in this type of device, when a barcode without an amount code is read, the amount data is forced to be entered, and the product cannot be registered unless the amount data is entered using the number keys and the amount keys. It has become. If you forget to enter the amount data key and read the barcode of the next product in this forced amount input state, an error state will occur. By operating the clear key in this state, the clear state will be canceled and the barcode will be read again. I'm trying to keep it on standby.

[Problems to be Solved by the Invention] However, in such a device, for example, when registering two products A and B with barcodes without price codes, after reading the barcode of product A, If the operator forgets to input the amount data using the key and reads the barcodes for the next 8 products, an error will occur. However, the operator misunderstands that the barcode for the daily sales amount has been read incorrectly and presses the clear key. After doing so, if the user reads the barcode of the daily product again and inputs the amount data for product B, product B can be registered, but product A remains unregistered.

This invention was made to solve this problem, and if you read the barcode of the previous product and are forced to enter the amount, an error will occur if you read the barcode of the next product. To provide a product vendor-event processing device which can prevent omissions in registration by returning to a standby state for forced input of the price of the previous product when a clear key is operated.

[Means for Solving Problems] This invention provides a barcode scanner for reading and inputting barcodes attached to products, a number key, and an amount key for registering the number key input as amount data. , a means for forcibly inputting the amount data using the numeric key and the amount key when there is no amount data in the barcode data read by the barcode scanner, and when the amount data is forcibly input by this means, the product is sold. A means for performing data registration processing, a means for checking whether or not the previous registration has been completed when reading a barcode by a barcode scanner, and setting an error state if the registration has not been completed, and an error caused by this means. A clear key is provided for canceling the state and placing the device in a state of waiting for input of amount data.

[Function] In the present invention having such a configuration, when a barcode without amount data is read with a barcode scanner, the amount data is forced to be inputted, and when amount data is entered using the numeric key and the amount key in this state, the product is sold. If the data registration process is performed and the barcode of the next product is read without inputting amount data in the extortion 1 input state, an error state will occur. If you operate the clear key in this error state, the error state will be canceled. and waits for forced input of amount data.

[Example code] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram, and 11 is a c that constitutes the main body of the control section.
pu <central processing unit ll), 12 is a ROM (read only memory) storing program data, 13
14 is a RAM (random access memory) equipped with various flags, memory for registration, memory for storing data being processed, etc., and 14 is a scanner interface that processes barcode data read by the barcode scanner 15. , 16 is a keyboard interface that processes key signals from the keyboard 17;
8 is a printer interface that outputs signals and print data to the drawer opening device 19 and printer drive circuit 20; 21 is a display interface that outputs display data to the display device 22; and 23 is, for example, a host computer (not shown). ) is a transmission controller that controls data transmission.

The CPU 11, ROM 12, RAM 13. Each interface 14, 16, 18, 21 and the transmission controller 23 are connected via a path line 24.

The drawer opening device 19 opens the drawer 25, and the printer drive circuit 20 drives and controls the printer 26.

When product sales data is input from the barcode scanner 15 and keyboard 17, the CPL 111 registers the product sales data in the RAM based on the program data in the ROM 12, and causes the display device 22 to display the registered data. , and causes the printer 26 to print the registered data.

The keyboard 17 has roOJ as shown in FIG.
rOJ NJ ~ "9" numeric key 17t, clear key 172, amount key 1 for inputting and processing data input using the numeric key 171 as amount data
7. A JAN key 174 for manually inputting the data input using the numeric key 171 as JAN code data, and a JAN key 174 for manually inputting the data input using the numeric key 171, and inputting the data input using the numeric key 171 as PLLJ data for single item registration. A PLLI key 175, a deposit/account key 176 for closing customer registration, and the like are provided.

When the JAN code is read and registered by the barcode scanner 15, the CPU 11 performs the processing shown in FIG. 3. That is, when a JAN code is input, a check is made to see whether or not the data of the previous entry has already been registered. If it is not already registered, an error state occurs. If the barcode has already been registered, it is then checked whether the barcode read this time is one for forced input of an amount (a barcode without an amount code). If the barcode is not a barcode that requires forced entry of an amount, the barcode also has an amount code, so the product sales data registration process is performed immediately. Also, if it is a forced input of the amount, enter the number key 1.
71 and amount key 173 to input amount data. If the clear key 172 is pressed in this state, the bar code is placed on standby for scanning again. When a numeric value is input using the numeric key 171, a numeric input process is performed. If the clear key 172 is pressed in this state, the system waits for input of amount data again. When a number is entered and the amount key 173 is entered, product sales data is registered based on the bar code taken in and the entered amount data.

Furthermore, if the clear key 172 is operated in an error state because the previous data has not been registered, the error state is canceled and the system waits for forced input of amount data.

In the embodiment of the present invention having such a configuration, when a JAN code that also includes price data is scanned and inputted by the barcode scanner 15 in a state where the previous registration has been completed, product sales data is generated based on the JAN code. is registered in the RAM 13. Further, if the JAN code does not have amount data, the key input of amount data is made to wait. In this state, when the clear key 172 is input, the read barcode is cleared and the barcode is put on standby for input to read the barcode again. Further, when a monetary amount is entered using the number key 171, the entered number is inputted. If there is a key input of the clear key 172 in this state, the inputted number data is cleared and the system waits for inputting the amount of money again. Therefore, if there is a mistake in the amount of money, it can be corrected. Furthermore, if the clear key 172 is pressed again in this state, the barcode data read this time will also be cleared, and the barcode will be placed on standby for input to read the barcode again. Therefore, without operating the amount key 173, it is easy to not only correct the amount but also re-enter the barcode data.

For example, if you read a barcode with no amount data and are forced to input amount data, if you accidentally read the barcode of the next product without entering the amount data, an error will occur. Become. Clear key 1 in this state
When the key 72 is input, the error state is canceled and the system enters a state where the amount data is forced to be entered. The operator then realizes that he has forgotten to input the amount data last time, and inputs the amount data using the number keys 171 and amount keys 173. This ensures that the previous product is registered.

After this, the barcode of the current product may be read again.

Further, in this device, the JAN code can also be input manually using the numeric key 171 and the JAN key 174. Further, if a PLU code is attached to the product, single item registration can be performed by inputting PLLj: ]-code using the number key 171 and the PLLI key 17s.

In the above embodiment, a case has been described in which a JAN code is used as a barcode, but the barcode is not necessarily limited to this, and other codes such as an EAN code may be used.

[Effects of the Invention] As detailed above, according to the present invention, if the barcode of the previous product is read and the price is forced to be entered, then an error occurs when the barcode of the next product is read. When the clear key is operated, the device returns to a standby state for forced input of the price of the previous product, thereby providing a product sales data processing device that can prevent omissions in registration.
