Description

[Detailed Description of the Invention] (1) Technical Field of the Invention The present invention relates to a POS (Point Of Sales, hereinafter simply referred to as "POS") terminal that aggregates and manages sales data in a retail sales floor, etc. Regarding equipment.

(2) Background of the technology Normally, after a POS terminal device is launched, a particular terminal device may become unusable due to a circuit failure or programming error. At this time, the center host machine to which the terminal device is connected is not affected by the terminal device that has become unusable because a spare terminal device is connected in place of the terminal device that has become unusable. It is desirable to be able to collect transaction data from the sales floor where the terminal device is installed, and even for the replaced terminal device, it is possible to receive the total sales from the center's host machine from the opening of the terminal device that became unusable to the time when it became unusable. Therefore, it is desirable to be able to continue adding up the total sales at the relevant sales floor.

(3) Prior Art and Problems However, conventional POS terminal devices use a transaction serial number, which is assigned to each transaction at the time of opening, and indicates the order in which the transactions occur.
Since only a fixed initial value such as "0" could be set as TNO, the replaced terminal device had
POS number, which is a unique number assigned to each terminal device
The POS number PNO attached to the terminal device that has become unusable cannot be used as the PNO (the same
Transaction data related to the same transaction serial number TNO from the POS number PNO will be rejected by the central host machine as an error, so the terminal device that has become unusable will have already recorded the transaction, and the transaction serial number TNO will be accumulated from the fixed initial value. POS number of the terminal device that has become unusable.
PNO cannot be used in a replaced terminal device where the transaction serial number TNO starts again from a fixed initial value. ), the total sales at the same sales floor,
On the center host machine side, it is necessary to add up the data for the terminal device that became unusable and the data for the terminal device that has since been replaced, and the data for both is stored on separate recording media such as magnetic tapes. etc., had the disadvantage that the tabulation work was extremely complicated. In addition, at the sales floor, with the replaced terminal device, only the total sales related to the transactions compiled by itself can be known, and if the sales floor is to be calculated including the sales of the terminal device that is no longer usable, Most relied solely on manual calculations.

(4) Purpose of the Invention In order to eliminate the above-mentioned drawbacks, the present invention eliminates the need to add up terminal devices that have become unusable and terminal devices that have been replaced on the center host machine side when calculating total sales. Moreover, it is an object of the present invention to provide a POS terminal device that allows the user to know the total sales including the amount of the terminal device that has become unusable from the terminal device that has been replaced.

(5) Structure of the Invention That is, the present invention is configured by providing a sales total requesting means that can request the center host machine for the sales total up to that point, and a transaction serial number setting means that can freely set the initial value of the transaction serial number. be done.

(6) Structure of the Invention The present invention will be specifically described below based on embodiments shown in the drawings.

FIG. 1 is a block diagram showing an example of a transaction recording system, and FIG. 2 is a block diagram showing an embodiment of a POS terminal device according to the present invention.

The transaction recording system 1, as shown in FIG.
It has a center host machine 2, and a plurality of POS terminal devices 5A, 5B, 5D are connected to the host machine 2 via a line 3.
...is connected. Each terminal device 5A, 5B, 5
As shown in FIG. 2, D... has a control section 6, and the control section 6 includes a sales total request instruction means 9 provided as a key switch on a keyboard 7, a POS number setting means 8, and a POS number setting means 8. The transaction serial number TNO setting means 10, the receiving means 11, the transmitting means 12, and the message creation and decoding means 13 are connected, and the decoding means 13
The setting means 8,
A memory 16 connected to a keyboard 7 provided with a keyboard 7 such as 10 is connected. On the other hand, the center host machine 2
has a transmitting means 17 connected to the receiving means 11 via the line 3, and a receiving means 19 connected to the transmitting means 12, and each means 17, 19 is connected to a transaction management control section 20. .

Since the present invention has the above configuration, each
POS terminal devices 5A, 5B, 5D, . . . are arranged in each sales floor, and a POS number PNO starting from “1” is stored in the memory 16 and attached to each device. For transactions that occur in the sales floor, data such as product name and sales amount are entered as transaction data DATA through keys provided on the keyboard 7 of each terminal device 5A, 5B, 5D, etc., and stored in the memory 16.
is stored in On the other hand, the control unit 6 sets the transaction serial number TNO in the memory 16 to the initial value "0" when the system 1 starts operating, such as opening a store, and thereafter sequentially changes the serial number every time a transaction is recorded. 1
The value is added to the transaction data DATA input from the keyboard 7 to the memory 16. Transaction data DATA stored in memory 16
is read by the message creation/decoding means 13 via the buffer memory 15 for each transaction serial number, and transmitted by the transmitting means 12 to the receiving means 19 of the center host machine 2 via the line 3, and then sent to the transaction management control section 20 of the host machine 2.
Then, the transaction data is organized and aggregated for each terminal device,
The total amount of sales is calculated as total sales. At this time, the transaction management control unit 20
is a transaction serial number that is the same as the transaction serial number TNO that has already been input from a terminal device with the same POS number PNO.
If transaction data DATA with TNO attached is input, the data DATA will be rejected as an error.

Here, if some kind of failure occurs in the terminal device 5A and the device 5A becomes unusable from now on, the operator should immediately disconnect the terminal device 5A from the line 3 and use another terminal device 5Z prepared as a backup. Connect to line 3. Next, the operator operates the POS number setting means 8 provided on the keyboard 7 to select the terminal device 5A that has become unusable.
POS number PNO attached to (in this case “1”)
is input and stored in the memory 16. Next, the operator inputs the transaction serial number corresponding to the last transaction data DATA sent from the terminal device 5A to the center host machine 2.
A value obtained by adding 1 to TNO is set in the memory 16 by the setting means 10 as the initial value of the transaction serial number TNO. That is, if the transaction serial number TNO of the device 5A is "NA"("NA" represents a specific number), the transaction serial number TNO of the device 5Z is "NA+".
1". Then, the operator operates the sales total request instruction means 9 on the keyboard 7 to send the sales total request signal TWC to the POS terminal device 5Z via the message creation and decoding means 13 and the transmission means 12. The transaction management control unit 20 of the host machine 2 receives the number and sends it out along with the POS number PNO.
TOTAL (the total amount up to the transaction serial number TNO corresponding to transaction data DATA that has been output from the terminal device 5A) is sent to the receiving means 11 of the replaced terminal device 5Z via the transmitting means 17, and the total amount is sent to the receiving means 11 of the replaced terminal device 5Z.
TOTAL is stored in the memory 16 via the message creation/decoding means 13 and the buffer memory 15. In this state, when the operator sequentially inputs transaction data DATA of transactions that occurred after the terminal device 5A became unusable from the keyboard 7, the control unit 6 assigns the transaction serial number TNO to “NA”.
+1" and add them one by one and store them in the memory 16. Then, the transaction serial number TNO of the transaction data DATA sent from the memory 16 to the host machine 2 via the line 3 is as follows. Terminal device 5
The serial number starts from "NA+1" in succession to "NA" which is the last serial number TNO output by A. Therefore, even if the terminal device 5Z sets the same POS number PNO as the device 5A, the host machine 2 cannot perform the transaction. Since the serial numbers TNO are different, device 5Z takes in data DATA from device 5A and 5Z without discarding it, and control unit 20 receives data from devices 5A and 5Z.
The amount of sales from the sales floor is calculated as total sales. In addition, the memory 16 of the terminal device 5Z contains information about the device 5 that has become unusable.
Since the total sales amount sent by A to host machine 2 up to the serial number TNO "NA" is stored, the sales amount of transactions after the serial number TNO is "NA+1" is the total sales amount up to the serial number TNO "NA".
It is stored in the memory 16 in the form of being added to the TOTAL, and therefore, the total sales total since the terminal device 5A opened at the relevant sales floor is added to the terminal 5Z.
You can know immediately from

In the above embodiment, the total sales of the POS terminal device 5A are stored in the memory 1 via the line 3.
Although the case where the sales total TOTAL is stored in the memory 16 has been described, it is also possible to store the total sales directly from the keyboard 7 in the memory 16 in case the line 3 is out of order.

(7) Effects of the Invention As explained above, according to the present invention, the sales total request instruction means 9 for requesting the center host machine 2 for the total sales up to that point and the initial value of the transaction serial number TNO can be freely set. Since the transaction serial number setting means 10 is provided, the replaced terminal device 5Z can replace the terminal device 5A which has become unusable.
Even if you set the same number as the POS number PNO attached to the POS number PNO, you can set consecutive values as the initial value in the device 5A as the transaction serial number TNO. The transaction data DATA can be collected as if the transaction data DATA were still being received, and the terminal devices 5A and 5Z, which were aggregated separately on the host machine 2 side as in the past, can be used to aggregate the total sales. You can eliminate the complicated work of adding up the parts. In addition, since the replaced terminal device 5Z side can also receive the total sales amount for the terminal device 5A that has become unusable from the host device 2, by adding the sales related to subsequent transactions to the total TOTAL point, , total sales of equipment 5Z
TOTAL is the sales since the opening of the device 5A at the relevant sales floor, and there is no need to manually tally the sales of the devices 5A and 5Z at the sales floor as in the past, which can contribute to the rationalization of the tallying office work.
