Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a sales data processing device such as an electronic cash register.

[Prior Art] Conventionally, in an electronic cash register (ECR),
Generally designed to be used by one person in charge, and in the ECR that adopted the two-person system,
It is designed so that one person can register sales data and another person can exchange money.

[Problems to be solved by the device] However, in the two-person system ECR, since the transfer of money is entrusted to another person in charge, the work efficiency can be improved, but the product code of the purchased product is input. The registration operation for registering must be performed by one person in charge, as in general ECR.

As a result, when the store is crowded and a plurality of customers are waiting for payment, the later customers will wait until the registration of the previous customer is completed and a receipt is issued.

In order to deal with such a case, multiple ECRs can be installed, but for small stores with limited store space, this is not the best solution, and product display space must be reduced. There was a problem such as not becoming.

An object of this invention is to enable two or more persons in charge to perform registration in parallel at the same time even with one sales data processing device.

[Means for Solving the Problems] Means of the present invention are as follows.

The data input means 1 (see the functional block diagram of FIG. 1, the same applies hereinafter) is for inputting sales data such as a product code, and is a bar code reader for optically reading a bar code (product code) from a product label or the like. A plurality of the data input means 1 are provided by a keyboard, a keyboard, or the like.

The data storage means 2 is a print buffer or the like which is provided corresponding to each data input means 1 and stores the sales data input from the corresponding data input means 1.

The registration end key 3 is a subtotal key or the like provided corresponding to each data input means 1.

The discrimination means 4 discriminates from which data input means 1 the sales data input from the data input means 1 has been input.

The storage control means 5 stores the sales data from the data input means 1 determined by the determination means 4 in the corresponding data storage means 2.
To memorize.

[Operation] The operation of the means of this invention is as follows.

Now, it is assumed that two bar code readers are prepared as the data input means 1. Here, for example, when the store is crowded and the queue of customers becomes long, two persons in charge perform registration using the bar code readers as the data input means 1, respectively.

Then, the determination means 4 determines which data input means 1 the input sales data was input from. In this case, the identification for identifying the input means to the sales data input from the data input means 1 If the code is added, it is possible to easily and surely make the determination.

Then, the storage control means 5 transfers and stores the input sales data to the data storage means 2 corresponding to the data input means 1. Therefore, the sales data input from the corresponding data input means 1 is sequentially stored in each data storage means 2.

Then, when the registration of one transaction is completed, the registration end key 3 provided corresponding to the data input means 1 just used is operated. Then, when the registration end key 3 is operated, the data in the data storage means 2 corresponding to the registration end key 3 is read out and output by printing or the like.

Therefore, since one sales data processing device allows two or more persons in charge to perform registration at the same time, it becomes possible to perform the registration work efficiently in proportion to the number of persons in charge, and as a result, in the store. You can also make effective use of space.

[Embodiment] An embodiment will be described below with reference to FIGS. 2 to 8.

FIG. 2 is a block circuit diagram showing the structure of the ECR.

The ECR is provided with two handy type bar code readers (hand scanners) 11 and 12, which are wired to the ECR main body. And each hand scanner 11, 12
Are provided with identification switches S1 and S2 for identifying the scanner. The barcode (product code) optically read from the product label or the like by scanning the product label or the like using the hand scanners 11 and 12 is stored in the internal memory (not shown) according to the operation position of the switches S1 and S2. The identification code unique to the scanner read from
It is taken into the CPU 15 via the corresponding input control units 13 and 14.

Further, the ECR is provided with a key input unit 16 that is usually provided, and the key code output corresponding to the operation key is taken into the CPU 15 via the input control unit 17.

CPU15 is code buffer CB, flag register flag1, flag
It is configured to have 2. Where code buffer C
B is an input buffer that temporarily stores the input product code and key code. Also, the flag register flag1, fla
g2 is a register in which a flag for specifying which subtotal key is operated when the subtotal 1 key KE or the subtotal 2 key KF is operated is set. And CPU15 is R
In addition to the data input process, the registration process is executed according to the microprogram stored in OM18. That is, CPU1
Reference numeral 5 registers the input sales data using the RAM 19, sends it to the display drive unit 20 and the print control unit 21 to display it on the display unit 22, and prints it on the registration paper set in the print unit 23. Let In addition, the CPU 15 opens the drawer 24 when a cash / deposit key, which will be described later, provided in the key input unit 16 is operated, and also executes change calculation as necessary and issues a receipt.

FIG. 3 shows the keyboard configuration of the key input unit 16. On this keyboard, a number key KA for registering the number of sales etc., a cash / deposit key KB for closing the cash sale registration, a clear for erasing the number mistakes. Key KC, multiplication / time key KD that performs multiplication registration with "quantity x unit price" and time display, hand scanner
Subkey 1 key KE, subtotal 2 keys provided for 11 and 12
In addition to having a KF or the like, it has a configuration including a mode changeover switch MS. In addition, the mode changeover switch MS corresponds to the changeover position, "P (setting)", "REG (registration)", "OFF".
This is a so-called control lock that switches each mode of "(power off)", "X (check)", and "Z (adjustment)".

FIG. 4 is a memory configuration diagram showing the configuration of the RAM 19.
The RAM 19 includes a PLU (price look-up) memory 19-1 and a transaction-specific memory 19-2 which are usually provided.
In addition, two subtotal memories, namely, cashier 1 subtotal memory 19-3 and cashier 2 subtotal memory 19-4 are provided corresponding to the cashiers using the hand scanners 11 and 12, and two printouts are provided. Buffer, that is, cashier 1 print buffer 19-5, cashier 2 print buffer 19-
6 is provided.

Next, the operation of this embodiment will be described.

Now, assume that the store is crowded and two cashiers perform PLU registrations for different customers. In this case, when the mode changeover switch MS is set to the registration mode, the cashier independently starts registration regardless of whether another cashier is currently registered.

Now, when the cashier scans a product label or the like using the hand scanner 11 (or the hand scanner 12), an identification code unique to the scanner is added to the product code read thereby, and the product code is written in the code buffer CB of the CPU 15.

If the product code is stored in the code buffer CB, the CPU 15 starts executing the registration process according to the flowchart of FIG. 5, and first checks whether the product code is stored in the code buffer CB. Yes (step A1), at this time, if the product code is not stored in the code buffer CB, no processing is performed, but if the product code is stored in the code buffer CB, it is detected in step A1. Then, in step A2, the PLU memory 19-1 in the RAM 19 is searched based on the product code in the code buffer CB, and the sales quantity and sales amount of the product are classified. Then, it is determined based on the identification code whether the product code has been input from the hand scanner 11 or the hand scanner 12 (step A3).

Now, when the product code is input from the hand scanner 11, first, the product unit price retrieved in step A2 is accumulated in the corresponding cashier 1 subtotal memory 19-3 (step
A4). Next, the product unit price is written together with the product name in the corresponding cashier 1 print buffer 19-5 (step
A5).

On the other hand, when the product code is input from the hand scanner 12, similarly, the contents of the cashier 2 subtotal memory 19-4 are accumulated and the product unit price is written in the cashier 2 print buffer 19-6 together with the product name (step A6). , A7).

Then, in any of the above cases, the process proceeds to step A8, and the registered product information (product name and unit price) is displayed on the display unit 22.
Display output (see FIG. 8).

FIG. 8 shows an example of the registration operation by the hand scanners 11 and 12 and the corresponding display and print state. It is normal that the product information is displayed every time the product code is input from the hand scanners 11 and 12. However, in this embodiment, the product information of the registered product is simply written in the cashier 1 print buffer 19-5 and the cashier 2 print buffer 19-6, and the receipt or the like is not printed.

In this way, when two cashiers perform parallel (mixed) registration using the hand scanners 11 and 12, the subtotal amount is set in the subtotal memories 19-3 and 19-4 for each cashier, and Print buffer with sales data for each cashier
It is set to 19-5 and 19-6.

Now, when the registration for one transaction with the hand scanner 11 is completed, the subtotal 1 key KE provided corresponding to the hand scanner 11 is operated. Then, the subtotal process according to the flowchart of FIG. 6 is executed. First, when it is recognized in step B1 that the subtotal 1 key KE has been operated, the subtotal amount is read out from the corresponding cashier 1 subtotal memory 19-3 and displayed (step B2). Then, the subtotal 1 key KE is supported. The flag "1" is set in the flag register flag1 (step B3). Therefore, when the subtotal 1 key KE is operated as shown in FIG. 8, the subtotal amount of the product registered using the hand scanner 11 is displayed.

Next, when the cash / deposit money key KB is operated, the closing process according to the flowchart of FIG. 7 is executed. First,
It is checked which of the flag registers flag1 and flag2 is set to "1" (step C1).
Since "1" is set in the flag register flag1,
Call the contents of the cashier 1 subtotal memory 19-3 (step C2), add it to the cash sale amount in the transaction-specific memory 19-2, and add the cash sale number "1" (step C4), and , Display the subtotal amount at this time as the cash sale amount together with the "current sale" symbol (step
C5). Then, the procedure proceeds to step C6 and the same check as in step C1 is performed, but in this case, since "1" is set in the flag register flag1, the procedure proceeds to step C7 and is stored and held in the cashier 1 print buffer 19-5. Reads all the existing data and prints it out. Therefore, a receipt having the print contents as shown in FIG. 8 is issued. In addition,
The contents of the cashier 1 print buffer 19-5 are then cleared (step C9).

Then, when the registration for one transaction using the hand scanner 12 is completed, the subtotal 2 key KF provided corresponding to the hand scanner 12 is operated. As a result, similarly to the above case, the subtotal process according to the flowchart of FIG. 6 is executed. This allows cashier 2 subtotal memory
The subtotal in 19-4 is displayed (step B4), and then "1" is set in the flag register flag2 (step B4).
Five).

Then, when the cash / deposit money key KB is operated, the closing processing according to the flowchart of FIG. 7 is executed as in the case described above. This allows cashier 2 subtotal memory
The subtotal amount is called from 19-4 (step C3), which is added to the cash selling amount in the transaction memory 19-2 and "1" is added to the number of cash selling items (step C).
Four). Then, the subtotal amount at this time is displayed together with the symbol "current sale" as the total amount of cash sale (step C5).
After that, all the data in the cashier 2 print buffer 19-6 is printed (step C8). Therefore, a receipt having the print contents as shown in FIG. 8 is issued. When the data in the cashier 2 print buffer 19-6 is printed in this way, its contents are cleared (step C9).

As described above, in this embodiment, even if the registration using the hand scanner 11 and the registration using the hand scanner 12 are mixed, it is possible to issue a receipt for each cashier.

It should be noted that although the above-described embodiment has two hand scanners,
You may provide three or more hand scans. Further, the hand scanner is not limited to the wired type, but may be a wireless type.

Further, the plurality of data input means may be keyboards, and further, one keyboard and one hand scanner may be used to perform registration in parallel.

[Effect of the Invention] In this invention, since two or more persons in charge can perform registration in parallel at the same time by one sales data processing device, it is possible to perform the registration work efficiently.
It is not necessary to install multiple sales data processing devices, which is effective in terms of store space.
