BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic cash register composed of a plurality of separable parts, and more particularly to an electronic cash register which stores sales data in a non-volatile memory.

[0002]

2. Description of the Related Art An electronic cash register for registering sales data in a store includes a cash drawer for storing cash, a keyboard for inputting transaction details, a printer for printing transaction details, a display for displaying transaction details, etc. However, if these are integrated, the size of the housing becomes large and a large space is required at the installation site. Therefore, each part of the electronic cash register is divided into a plurality of modules, each module is connected through an interface and a cable, and each module can be installed at an arbitrary position within a certain range. There is an electronic cash register. In controlling each module related to sales processing in the electronic cash register having such a modular structure, for example, as shown in FIG. 6, a control CPU for executing sales processing is housed in a main module, and a keyboard and a printer are installed. And a display, etc. are independently provided in separate housings, and the CPU of the main module controls these keyboard, printer, and display (see FIGS. 6A and 6B).
There is. However, in such a configuration, the sales process and the control of each input / output device are performed by a single CPU. Therefore, when a part of the processing operation is changed according to the usage mode, the software of the CPU is used. The entire piece of clothing has to be changed, which complicates the work. Therefore, a sub CPU for controlling each input / output device is provided in each housing, and data is input / output between the sub CPU and the main CPU in the main module (FIG. 6).
(See (C)).

[0003]

However, as shown in FIG.
In the electronic cash register having the configuration shown in (C), although each module can be installed at any position within a certain range, input / output devices such as a keyboard, a printer, and a display are separated from the main module, and the main module is separated. It also becomes possible to operate by a device other than the above. Therefore, it is possible to print transaction contents different from the sales data created in the sales process of the main CPU on the printer or display them on the display, and to control all the sales data subject to taxation on the printer and the display. There was a problem that it could not comply with the laws and regulations of Italy, Greece, etc. that must be stored in a non-volatile memory (fiscal ROM) by the same CPU.

An object of the present invention is to provide a first sales processing section for creating sales data in a main module and a second sales processing section for create display data, print data and storage data in a sub-module. An object of the present invention is to provide an electronic cash register in which each part can be installed separately while satisfying the laws and regulations regarding storage of sales data.

[0005]

As shown in FIG. 1, the electronic cash register of the present invention comprises a main module having a first sales processing section for preparing sales data based on operation data of a keyboard. A second sales processing unit that creates display data, print data, and storage data based on the data input from the printer, a printer that is driven by the print data, and a registration storage unit that stores the storage data, as a sub-module. It is provided.

In the electronic cash register according to the second aspect of the present invention, the second sales processing section creates sales data, and the sales data created by the first and second sales processing sections. Comparing means for comparing
The sub-module includes an operation stopping unit that stops the operation of at least the second sales processing unit when both sales data do not match in the comparison unit.

[0007]

According to the present invention, the sales data is created in the first sales processing section of the main module based on the operation data of the keyboard, and the display data, the print data and the printing data are output based on the data output from the main module in the sub module. Saved data is created. The display is driven according to the display data, the printer is driven according to the print data, and the storage data is stored in the registration storage unit. Therefore, when the sub-module is configured in the housing including the printer, the keyboard, the main module, the sub-module and the display can be configured separately from each other, and the display can be displayed by the second sales processing unit provided in the sub-module. The printer and the registration storage unit are controlled, and the legal regulations regarding tax management can be satisfied.

When the sales data created by the first sales processing section of the main module and the data created by the second sales processing section of the sub-module are compared by the comparison means, and both do not match. Then, the operation of the second sales processing unit is stopped, and the operation of the display and the printer is immobilized. Therefore, when data different from that of the main module is input to the sub module, the transaction processing is not executed, and it becomes impossible to store the data of the content different from the actual transaction content in the registration storage unit.

FIG. 5 is a flowchart showing the processing procedure of the control unit of the electronic cash register. The CPU 11, which is the first sales processing unit provided in the main module 1, waits for a key input from the keyboard 2 (n1) and reads the operation data when the keyboard 2 is operated and the operation data is input. (N2), and sales processing for creating sales data based on the input operation data is executed (n3). Next, transmission data including the generated sales data and operation data of the keyboard 2 is generated (n4), and this is transmitted to the CPU 15 which is the second sales processing unit of the submodule 3 (n5). After that, the data in the file created in the predetermined memory area of the RAM 13 is updated (n6).

The CPU 15 of the sub-module 3 waits for input of transmission data (n11), receives the transmission data from the CPU 11 (n12), and receives sales data from the operation data included in the transmission data. Create (n13). Next, the sales data included in the transmitted data,
That is, the sales data created by the CPU 11 is compared with the sales data created by the own sales process, and it is determined whether the two match and whether the display 4 is connected (n14, n15). ).

When both sales data match and the display 4 is connected, display data is created and output to the display 4 (n16, n17),
Create print data and supply it to the printer 6 (n18,
n19). After that, the data in the file in the RAM 17 is updated (n20), and the sales data is stored as the storage data via the read / write control unit 20 to the fiscal R.
