In the above-described configuration, the present invention has an independent POS register function and a sub-CP corresponding to each terminal.
U and sub-storage means are responsible for data exchange with the terminal. Data from the terminal is stored in the corresponding sub-storage means by the transmission means of the corresponding sub-CPU, and this operation is executed independently from other terminals. The main CPU reads data from each sub-storage means in a predetermined order and intensively processes the data, and writes instructions to each input means into the corresponding sub-storage means. The corresponding sub-CPU transmits the instruction to the input means, and display or printing is performed on the display means or printing means.

Embodiment Hereinafter, a POS register according to an embodiment of the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram showing a configuration in which a POS register according to an embodiment of the present invention connects two terminals. In the figure, two terminals 19 are installed in the POS register main body 18 of this embodiment, each with a sub CPU.
It is connected by data transmission means. The main body of the POS register includes a main CPU 1 that controls the operation of the entire device, a main storage means 2 composed of an IC memory, and an FDD 4).
(The main storage means 23 is composed of an auxiliary storage means such as a DD5 and a ROM 3 for storing main programs, etc.), peripheral devices 6 are connected to the main CPU, and a plurality of dual port RAMs (hereinafter referred to as sub storage means) are connected to the main CPU. A sub CPU 5 is provided to control data transmission for each of the sub storage means 7, and one of the sub CPUs is provided with an input/output means composed of an input means 2o, a display means 21, and a printing means 22. The input means 2° includes an input device 11 operated by an operator, and a secondary sub-C that controls output of data to the sub-storage means via the sub-CPU.
It is composed of a PU 5 and a ROM 10 that stores its operating program. The display means 20 is composed of a display 14, a secondary sub-CPU 12 that controls the display of data in the storage means 7 via the CPU, and a ROM 13 that stores its operating program. The printing means 22
The secondary CPU 15 includes a secondary CPU 15 that controls printing of data in the sub-storage means via the sub-CPU, and a ROM 16 that stores its operating program. The terminal device 19 is equipped with only input/output means consisting of the input means 2o, display means 21, and printing means 22, and has no sub-CP other than the main body.
It is connected to the transmission means by U, and inputs and outputs the data of the terminal to the corresponding sub-storage means. The input/output means of this terminal has the same configuration as that for the main body. The main storage means 2 is loaded with high-speed processing resident programs and resident files, the FDD 4 and HDDs are written with system programs, overlay programs that are loaded whenever necessary, tallying files, mask files, etc., and the ROM 3 is loaded with resident programs and files. It is the same as a conventional POS register in that initialization software when the power is turned on, a boot program for loading the main program into the main storage means, etc. are written therein. The features of the present invention are that the POS register main body and each terminal have independent RAM (sub storage means) 7, and the terminal RAM (sub storage means) 7, sub CPU 5, and terminal sub CPU 8 are independent. It is important to prepare accordingly. The operation in the above configuration will be explained. When the power is turned on and operation begins, the POS register main body becomes an independent POS register with built-in input means 2, display means 21, and printing means 22.
It functions as an S register, and data from the input means 20 is transmitted and controlled by the sub CPU 5 and input to the RAM 7, and display and print data from the main CPU 1 is input to the RAM 7 and transmitted to the RAM 7 and controlled by the sub CPU. This is executed by the display means 21 or the printing means 22. On the other hand, data from the input means 2° of the terminal 19 is transmitted and controlled by the sub CPU 5 and input to the RAM 7.
The display and print data from 1 is written into the RAM 7, transmission controlled by the sub CPU 8, transmitted to the terminal 19, and executed by the display means 21 or the print means 22. Data transmission can be carried out, for example, by simple serial data transmission means of connecting lines. Further, by assigning an individual number for each terminal to the data from each terminal, the data can be distinguished. This distinction is not only necessary for shaking hand operations between the main unit and the terminal, but can also be used, for example, to differentiate data by department. Data input/output from the main unit and each terminal is input/output to the main CPU via independent sub-CPUs and RAMs, and even when the main unit and terminals are operated at the same time, each data is simply input to each RAM. The main CPU separates and handles the data in a predetermined order.

FIG. 2 shows a main body 23 of a POS register according to an embodiment of the present invention.
2 is a wiring diagram showing a configuration in which two terminals 24 and 25 are connected to each other. The main body 23 functions as a single register, and the terminals 24 and 25 connected thereto input and output data using transmission means built into the main body 23.
