Abstract

PURPOSE:To prevent the sequence of input of data from both a keydoard and a scanner from being deviated in order by comprising the device so that data inputted from the keyboard or the scanner can be accumulated in the sequence of input, and it can be outputted in sequence of output. CONSTITUTION:When the read operation of a bar code is performed with a bar code scanner 3 at a data input device 2, scanner read data at that time is stored in a RAM 13 with data length. Also, when the input operation of various kinds of keys on the keyboard 4 are performed, key input data at that item is stored in the RAM 13 with runlength. Therefore, input data can be stored in the RAM 13 in the sequence of input in spite of its input destination. The data stored in the RAM 13 is transmitted to an electronic cash register 1 in sequence of accumulation. Meanwhile, at the register 1, it is decided from which input data reception data is based on the data length of the reception data, and a data processing corresponding to a decided result is executed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a data input device that can input product sales data from a keyboard and a scanner unit, and products such as electronic cash registers using this input device. The present invention relates to a sales data processing device.

[Prior Art] Conventionally, electronic cash registers used in mass merchandisers such as supermarkets have a bar code attached to the product, in addition to a keyboard for inputting the number of products sold and the sales amount. There is a device that allows the registration of sales products by connecting a barcode scanner for reading and reading the barcode attached to the product using the barcode scanner.

In such an electronic cash register, the central processing unit (CPU) as the control unit interrupts key data processing when any key on the keyboard is inputted and key input data is read through the keyboard circuit. When the barcode is read by the Nokuichi code scanner and the data read by the scanner is taken in via the communication means in a predetermined transmission procedure, the corresponding scanner data processing is executed by interrupt.

Therefore, key input data input from the keyboard is immediately taken into the CPU and processed, but scanner read data input from the barcode scanner is delayed by the time required for communication (for example, 600 as) and then processed by the CPU.
The data will be imported into U and then processed.

Therefore, if you input data on the keyboard immediately after reading a barcode using the Tsuku-code scanner, the data from the keyboard will be imported into the CPU first, and the data from the keyboard will be received by the CPU faster than the data read by the scanner. In some cases, the data was processed first.

For this reason, conventional electronic cash registers cannot prevent the following problems.

For example, when registering a product eligible for a discount, the product's barcode is read with a barcode scanner, and then the discount rate is entered from the keyboard, but if the discount rate is entered too quickly, the barcode is read just before the product. Discount processing is performed on the purchased products. Also, if the closing operation performed by inputting the closing key is too early, the item whose barcode was last read will not be included in the customer's total.
It will be processed as a registered product for the next customer.

[Problems to be Solved by the Invention] As described above, in conventional electronic cash registers etc. equipped with a keyboard and a barcode scanner as data input means, the data input sequence seen from the CPU side and the actual data input sequence are different. may become misaligned,
There was a risk that incorrect data processing would be executed. Therefore, the operator had to be careful when operating the keyboard after operating the scanner, resulting in poor operability.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a data input device with excellent operability, without the fear that the order of inputting data from a keyboard and the order of inputting data from a scanner are out of sync.

Another object of the present invention is to provide a product sales data processing device that can improve operability for an operator without causing a lag in the data input sequence between the keyboard and the scanner.

A data input device comprising: a scanner unit for reading data from the keyboard or the scanner unit; a data storage unit that stores data input from the keyboard or the scanner unit in the order of input; and a data output unit that outputs the data accumulated by the storage unit in the order of input via the communication unit. The main body of the data processing apparatus includes a data reception control means that receives output data from the data input device via a communication means, and a scanner unit that determines whether the data received by the reception control means is key input data from the keyboard or not. data determining means for determining whether the data is scanned by the scanner;
and data processing control means for executing data processing of the received data based on the determination result by the determination means.

[Operation] In the data input device of the present invention, data input from the keyboard or scanner section is accumulated in the order of input,
Since the data are outputted in the order of accumulation, there is no risk that the data input sequence from the keyboard or scanner section and the actual data input sequence will deviate.

In the product sales data processing device using the above data input device, key input data from the keyboard and scanner read data from the scanner are transmitted using the same communication means, so product sales data processing is performed. There is no possibility that the data input sequence from the keyboard or scanner section and the actual data input sequence will deviate from each other when viewed from the device side.

FIG. 5 is a block diagram showing the configuration of the electronic cash register 1, in which a CPU 51 as a main body of the control unit includes an arithmetic circuit, a memory control circuit, etc. .

"Payment" 7 ROM 53' storing programs for executing various operations such as "setting", RAM 54 equipped with a storage section for cumulatively registering sales data of products registered for sale through product registration operations; A clock circuit 55 that measures the current time; a transmission control circuit 56 and a 110 (input/output) board that controls data transmission between the data input device 2 and the communication means 5 according to a predetermined transmission procedure; 57, keyboard circuit 58, display system a circuit 59
, I10 port 60, respectively.

A mode switch 61 is connected to the I10 boat 57 for controlling power on/off and for selecting the various business modes and notifying the CPU 51 of the execution thereof.

A keyboard 62 is connected to the keyboard circuit 62 and has the same keys as the keyboard 4 in the data input device 2 shown in FIG.
It is designed to take in key input data from 2.

A display 63 is connected to the display control circuit 59 for electronically displaying the price of the sold product, the total price, etc., and the display 63 is driven and controlled to display and output display data such as numbers.

Connected to the I10 boat 60 are a printer drive circuit 65 of a printer 64 that prints on receipts, etc., and a drawer opening device 67 of a drawer 66 for storing cash, etc., and each of them responds to instructions from the CPU 51. A drive signal is output accordingly.

The CPU 1 of the data input device 2 is program-controlled to execute the processing shown in FIG. 6 in response to turning on the power (not shown). That is, when the power is turned on, after performing initialization processing such as clearing the input data buffer 21 in the RAM 13 and initializing (-1) the read pointer RP and write pointer WP in the area 22.23, the barcode scanner 3 Alternatively, the presence or absence of input data from the keyboard 4 is monitored. When scanner read data is read from the barcode scanner 3 via the scanner control circuit 15, the data length of the scanner read data is first written into the first byte of the corresponding area of the input data buffer 21 specified by the write pointer WP. Then, the scanner read data is stored in the same area. Thereafter, the write pointer WP is updated by "+1" and the process returns to the input data presence/absence determination process.

In contrast, the keyboard 4 via the keyboard circuit 16
Even when key input data is imported, the data length of the key input data is first stored in the first byte of the corresponding area of the input data buffer specified by the write pointer WP, and then the relevant scanner read data is stored in the same area. Store.

However, in this embodiment, the key input data is 1 byte,
All data lengths are [01].

Thereafter, the write pointer WP is updated by "+1" and the process returns to the input data presence/absence determination process.

Further, when it is detected that data is being input to the input data buffer 21 in a state where there is no input data from the barcode scanner 3 or the keyboard 4, it is determined that there is data to be transmitted. First, the data length and data are extracted from the corresponding area of the input data buffer designated by the read pointer RP, and transmitted to the electronic cash register 1 via the transmission control circuit 14 according to a predetermined transmission procedure. After that, set the read pointer RP to “+1”.
is updated, and the process returns to the input data presence/absence determination process.

Note that the write pointer WP and read pointer R
In the updating process of P, if the write pointer WP and read pointer RP exceed the number of areas of the input data buffer 21, they are automatically initialized to "1".

On the other hand, the CPU 51 of the electronic cash register 1 transmits the data transmitted from the data input device 2 to the transmission control circuit 5.
The program is controlled to execute the processing shown in FIG. 7 when the data is received in a predetermined transmission procedure via the computer 6. That is, when it is determined that data has been received from the data input device 2, the data length of the first byte of the received data is checked. When this data length is confirmed to be 1-byte data [01], it is determined that the received data is key input data on the keyboard 4 of the data input device 2, and the key input data input from the keyboard 62 is Execute the same key data input process as in the case.

On the other hand, if it is confirmed that the data length is other than 1-byte data, it is determined that the received data is the scanner read data of the barcode scanner 3 in the data input device 2, and the same scanner data input process as before is performed. Execute.

In the data input device 2 of this embodiment configured as described above, when a barcode reading operation is performed by the barcode scanner 3, the scanner read data at that time is transferred to the input data buffer 21 along with the data length.
The data is stored in the area specified by the write pointer WP. Further, when input operations are performed on various keys using the keyboard 4, the key input data at that time is stored in the area specified by the write pointer WP of the input data buffer 21 together with the data length [01]. Therefore, data input from the barcode scanner 3 and the keyboard 4 are stored in the input data buffer 21 in the order in which they are input, regardless of the nature of the data. and,
The data accumulated in the input data buffer 21 is transmitted to the electronic cash register 1 via the communication means 5 in the order of accumulation, that is, in the order of input, according to a predetermined transmission procedure.

On the other hand, in the electronic cash register 1 which receives data from the data input device f2 via the communication means 5 in a predetermined transmission procedure, the data length of the received data indicates that the received data is scanner read data by the barcode scanner 3. It is determined whether the input data is key input data from the keyboard 4, and data processing corresponding to the determination result is executed. Therefore, there is no possibility that the data input sequence in the barcode scanner 3 and the keyboard 4 deviates from the actual data input sequence processed in the electronic cash register 1.

As a result, for example, when an operator registers a product eligible for a discount, after the operator reads the barcode of the product with the barcode scanner 3, the number key 3 of the keyboard 4 is immediately pressed.
A discount rate is entered by operating the discount key 42, but no matter how quickly the discount rate is entered, the discount process will not be applied to the product whose barcode was read immediately before the product in question. No problems will occur. Also, the deposit/cash key 34 of the keyboard 4. Shinkei key 35. Multimeter key 36
No matter how quickly the closing operation is performed by input operations such as , etc., a problem may occur where the last product whose barcode is read is not included in the customer's total and is processed as the next customer's registered product. Nor. In this way, the operator who operates the data input device 2 does not have to pay any attention to keyboard operations after operating the scanner, resulting in excellent operability.

In the above embodiment, the keyboard 4 of the data input device 2
Although keys similar to those on the keyboard 62 of the electronic cash register 1 are provided in the data input device, only the keys that generate key input data that may cause problems when the data input sequence deviates from the data read by the scanner are used as data input devices. 2
The effects of the present invention can be sufficiently exerted simply by disposing it on the keyboard 4 of the present invention. Further, instead of the barcode scanner 3, a data input device using an OCR (optical character reader) that optically reads characters may be used.

It goes without saying that the data input device 2 of the present invention can be connected to a terminal in a POS (point of sale) system via communication means.

[Effects of the Invention] As described in detail above, according to the present invention, there is no fear that the order of data input from the keyboard and the order of data input from the scanner will deviate, and it is possible to provide a data input device with excellent operability.

Further, according to the present invention, it is possible to provide a product sales data processing device that can improve operability for an operator without fear of causing a shift in the data input sequence between the keyboard and the scanner.
