Abstract

PURPOSE:To prevent the whole of a system from getting unoperatable at the time of trouble of any electronic cash register (ECR) by providing all connected ECRs with the same guest check file. CONSTITUTION:When a new check key to generate a new guest check file is inputted from a key board 23 of one ECR, a CPU 20 generates the new guest check file in a RAM 22. A command and a guest check number for guest check file generation are outputted to a transmission line 10 through a transmission circuit 26 for the purpose of guest check files having the same name in the other ECRs. When receiving data, ECRs decode the command and confirm the command for new guest check file generation to generate guest check files in their own RAMs. Consequently, all ECRs have the same guest check file. Thus, the whole of the system is prevented from getting unoperatable.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic can register (hereinafter referred to as ECR) device used mainly in restaurants and the like.

Conventional technology For example, in a restaurant, a menu ordered by a deceased customer is registered in the KCH, and when the customer leaves, taxes, totals, etc. are calculated based on the registered data, and checkout is performed. Are known. When realizing this with multiple KCRs, one mask KOR is connected to other slave KCRs, and the KOR is configured with customer information such as sales amount and table pick-up (hereinafter referred to as guest check file) in the mask KCH. There is a device. In such a KCR, when a customer code is entered manually from one of the slave ICGHs, that customer code is transmitted to the mask KCH, and the master EGR reads data corresponding to that customer code from the guest check file and sends it to the slave ECH. Transmit it to. The slave RCR performs additional processing and checkout processing.

Problems to be Solved by the Invention However, in the above conventional ICOR device, the master E
If the GR breaks down, it will no longer be possible to read the previously registered guest check file or create a new guest check file. That is, when the mask [R recovers to 1, the entire system becomes inoperable.

In particular, once the guest check file stored in the mask KCH is deleted, it is almost impossible to restore it.

The present invention solves these conventional problems, and aims to provide an excellent IEOR device in which the entire system does not become inoperable even if the mask KCR fails.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention operates [updating the guest check file in R] when creating, adding, or deleting a new guest check file. , After that, all NOHs were equipped with a function to transmit the updated information to all connected KCHs.
The same guest check file is provided for both.

Therefore, according to the present invention, all connected KGRs have the same guest check file, so even if any KCR fails, the entire system can be prevented from becoming inoperable.

Embodiment FIG. 1 is a schematic diagram of the overall structure of an electronic cash register device according to an embodiment of the present invention. In Figure 1,
XC;R1 to KCRn are each connected by a transmission line 1o.

FIG. 2 is a schematic block diagram of each ECH.

Referring to FIG. 2, the %OPU 20 controls the entire operation including calculation control and I/O control according to a program pre-recorded in the ROM 21. The keyboard 23 inputs key codes such as menu codes and customer codes.
Tell PU20. 1. A printer 24 that prints menu codes, sales amounts, etc. input from the keyboard 20.
A display 26 is connected to display this. Furthermore, the transmission circuit 26 is for transmitting data between each ROR, and the RAM 22 records guest checkout files, menu information, sales amounts, and the like. Third
The figure is a flowchart for explaining the specific operation of an embodiment of the present invention.

Next, the operation of the above embodiment will be explained. 1. When the new check key for creating a new guest check file is input from the keyboard 23 of one KCH connected to the system, at step 30, CPυ20 creates a new guest check in I{AM22. Create a file. Then, in order to create a guest check file with the same number in the other 11H, the guest check creation command and the guest check number are outputted to the transmission line 10 via the transmission circuit 26 at 31. After the output, it waits at 1 for a reply indicating that it has been correctly received from all other XCRs at 32. On the other hand, the KCR who died at 33 and received the data interprets the command at 34, confirms the new guest check creation command, and presses 36 to create a guest check file in its own RAM. and 3
6, a reply indicating that the file has been created is sent after a certain period of time. In this way, all connected KCRs create a guest check file in their RAM, allowing all ECRs to have the same gust check file. To update or delete files, change the command to update or delete the guest check files of all ECRs in the same way as above.

Effects of the Invention As is clear from the above embodiment, the present invention is such that all connected NCRs have the same guest check file9, so even if any KCR fails, other RCRs will not be affected. Since it has a guest check file, it has the effect of preventing the entire system from becoming inoperable.
