Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention is preferably applied to an electronic cash register installed in each store and connected to a host computer installed in the main store by an online line. Regarding processing method.

<Prior Art> Conventionally, in a department store or a supermarket, a host computer installed in a head office or a central processing center and an electronic cash register arranged in each store are connected by an online line to the electronic cash register in each store. A sales management system that collectively processes the sales data of the above at the central point and the central processing center is implemented.

In such a sales management system, the electronic cash register of each store holds sales in a predetermined area of a storage unit included in the electronic cash register together with so-called cash register operations. Then, when a settlement job, which is one of the jobs of the electronic cash register, is instructed from the input unit included in the electronic cash register, the electronic cash register first stores the sales data stored in the storage unit. Is transmitted to the host computer via an online line such as a telephone line, and then a predetermined calculation process is performed on the sales data and the calculation result is held in a predetermined area of the storage unit and the sales data is stored in the electronic cash register. The included printing unit prints and outputs to a receipt journal, deletes the sales data from the storage unit, and ends the settlement job.

<Problems to be Solved by the Invention> When the electronic cash register executes the above-mentioned settlement job, the online line may not be available and the sales data may not be transmitted to the host computer. However, if you continue the settlement job without sending the sales data to the host computer, the sales data will be erased from the storage unit,
This will hinder the collective sales management by the host computer. Therefore, the settlement job could not be executed in the above cases. In addition, usually the settlement job is often performed after the store is closed, and if the settlement job cannot be executed, the day's work of the electronic cash register is not completed, and the working hours of the operator are affected.

In view of the above points, an object of the present invention is to provide a settlement processing method for an electronic cash register that can execute a settlement job without loss of sales data even if the sales data cannot be transmitted to the host computer.

<Means for Solving Problems> The present invention is an electronic device that is connected to a central control device via an online line, transmits sales data to the central control device when a settlement job is executed, and then executes a settlement process for the sales data. In the electronic cash register, the electronic cash register includes a sales data memory for storing sales data and a transmission data memory for storing data to be transmitted to the central control unit, and the electronic cash register is responsive to an instruction of a settlement job. Regardless of whether the online line is usable or not, the capacity of the sales data held in the sales data memory is compared with the empty area of the transmission data memory, and the empty area of the transmission data memory is the sales area. If it is smaller than the data capacity, it prints out that the transmission data memory is full and pays without sending the sales data. If the empty area of the sales data is equal to or larger than the capacity of the sales data, the sales data held in the sales data memory is transferred to the transmission data memory, and then the sales data settlement process is performed. After the sales data stored in the transmission data memory is transmitted to the central control unit when the online line is available, the sales data settlement process is executed and the sales data stored in the transmission data memory is executed. Data is to be sent to the central controller when the online line is available.

<Operation> According to the present invention, the sales data stored in the sales data memory is used regardless of whether the online line can be used or not when executing the settlement job of the electronic cash register connected to the host computer by the online line. After the transfer to the transmission data memory, the settlement processing of the sales data in the sales data memory is executed. Then, the sales data held in the transmission data memory is transmitted to the host computer when the online line is available.

<Examples> Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a sales management system. In such a sales management system, for example, a host computer 1 which is a central control device installed in a head office or the like and an electronic cash register 2 installed in each store and connected to the host computer 1 by an online line such as a telephone line. Communicate with each other. The electronic cash register 2 includes a control circuit 3 and transmits / receives data to / from the host computer 1 via an interface 4. Further, the control circuit 3 includes a plurality of files 9a to 9c (hereinafter referred to as files) realized by a read-only memory 5 and a random access memory in which programs for performing cash register operations and various jobs in the electronic cash register 2 are stored. 9) and the transmission file 10 are connected. Further, the control circuit 3 controls the display unit 5 and the key input unit 6 for performing cash register operations and various jobs, and the printing unit 7 for printing on a receipt / journal.

The operation of the settlement job of the electronic cash register 2 will be described with reference to the flowchart of FIG. The electronic cash register 2 stores the sales as sales data in the file 9 together with the cash register operation. When the checkout operation is completed and the user wants to make a payment, a payment job command is input from the key input unit 6. By this input, the operation of the flowchart of FIG. 2 is executed, and if the sales data capacity held in the file 9 in step n3 is less than the free memory capacity of the transmission file 10, the process proceeds to step n4. File to send sales data in step n4
Transfer to 10 and check whether online transmission is possible in step n5. If transmission is possible, the process proceeds to step n6, the sales data held in the transmission file 10 is transmitted to the host computer 1 via the interface 4, and step n7
The sales data held in the transmission file 10 is erased, and the process proceeds to step n8. If the sales data capacity is larger than the free memory capacity of the transmission file 10 in step n3, the process proceeds to step n9, where the printing unit 7 prints out "transmission file Fu11" in the receipt journal, and proceeds to step n8. Furthermore, if online transmission is not possible in step n5, the process directly proceeds to step n8. In step n8, the sales data is settled, and the settlement job is ended.

When the settlement job is instructed as described above, the electronic cash register 2 transfers the sales data stored in the file 9 to the transmission file 10 regardless of whether the online line is available or not, and then the sales data is transferred. Execute the settlement process of. At this time, if the online circuit is available, the sales data held in the transmission file 10 is sent to the host computer 1. If the online line is unavailable, the online line can be used at the time of the next settlement job execution. Send sales data at any time. Further, in the above embodiment, when the sales data is larger than the free memory capacity of the transmission file 10 in step n3, the procedure proceeds to step n9 and the settlement process is executed in step n8, but it may return to the initial state after the operation in step n9. .

<Effects of the Invention> According to the present invention, even if the sales data cannot be transmitted to the host computer in the payment job of the electronic cash register, the payment job can be executed without loss of the sales data. It is possible to execute the settlement job at any time without receiving, and it is effective in that the processing work by the electronic cash register can be made more efficient, and in particular, the online line can be used in response to the instruction of the settlement job, Regardless of whether or not it compares the capacity of the sales data held in the sales data memory with the empty area of the transmission data memory,
If the empty area of the send data memory is smaller than the sales data capacity, print out that the send data memory is full, and make the adjustment without sending the sales data. Transfers the sales data held in the sales data memory to the transmission data memory, so the most suitable process is selected from the comparison of the amount of data to be sent and the empty area of the transmission memory. Since the settlement process can be performed without performing the transmission process, the result is that the settlement process becomes efficient.
