There were problems such as poor register portability and increased cost.

Furthermore, in the above-mentioned conventional technology, a plurality of auxiliary cash registers share the arithmetic processing of the main cash register, and a plurality of independent product registration units are connected to the main cash register. No consideration has been given to the provision of a multi-person electronic cash register where payments can be made using a cash register, and in the conventional system described above, multiple product registration sections are required to construct a multi-person electronic cash register. A new auxiliary cash register must be developed, and a means for connecting the newly developed auxiliary cash register and the main cash register must also be newly developed.

An object of the present invention is to connect the input/output device dedicated to the electronic cash register, which is most frequently used by the operator, to the keyboard device for the electronic cash register, which the operator uses most frequently, to the POS basic unit. The object of the present invention is to construct an electronic cash register that is easy for the operator to use.

Another object of the present invention is to easily construct a multi-person electronic cash register by making it possible to connect a plurality of the keyboard devices to which the input/output device of the electronic cash register is connected to the POS basic unit.

[Means to solve the problem]

In order to achieve the above object, an electronic cash register is connected to a keyboard device for the electronic cash register, which is connected via a serial interface to the POS basic section consisting of an arithmetic processing section, a line control section, and a printer control section. It has the added function of controlling various input/output devices (magnetic card reader, password input device, scanner, operator display, customer display) dedicated to cash registers.

Further, in order to easily construct a multi-person electronic cash register, the keyboard device for the electronic cash register having the function of controlling the PO8 control unit and the input/output device for the electronic cash register is provided. A plurality of units can be connected via a serial interface, and the unit has a product approval unit and a product registration function configured by connecting one POS basic unit and one electronic cash register keyboard device via the serial interface. A multi-person electronic cash register is constructed by connecting a plurality of the keyboard devices through the serial interface.

[Effect]

In the electronic cash register keyboard device connected to the POS basic unit through the serial interface, a processor controlling the built-in keyboard includes an input/output device (magnetic card reader, PIN code input device) dedicated to the electronic cash register. equipment, scanner,
The operator display (2 customer displays) is controlled, and the PO
It operates to transmit and receive data between the S basic unit and the serial interface. Thereby, data input/output from the input/output device is transmitted/received to/from the POS basic section by the processor in the keyboard device, so that malfunctions will not occur.

Further, a plurality of the keyboard devices are connected to the PO8 basic unit through the serial interface. Said po
An iD code indicating a unique address is given to each of the plurality of keyboard devices connected to the s basic section, and the PO8 basic section operates to access each of the plurality of keyboard devices using the iD code. Thereby,
The PO8 basic section collectively manages the properties registered as products using the plurality of keyboard devices, and the PO8 basic section performs product approval for the product registration (product payment amount, product name, etc.) performed using the plurality of keyboard devices. Work like you do. Thereby, it is possible to easily construct a multi-person electronic cash register in which multiple operators can register multiple products.
