Embodiment An embodiment will be described below with reference to FIGS. 1 to 5.

FIG. 1 is a system configuration diagram of a sales data processing system, in which a plurality of slave electronic registers (hereinafter, referred to as slaves) SL and one master electronic register (hereinafter, referred to as master) MS, They are connected by an inline L so that they can transmit data to each other.

The components of the slave side SL and the master side MS are the same,
As shown in FIG. 2, each has a CPU 1, a ROM 2, a key input unit 3, a RAM 4, a display unit 5, a printer 6, a transmission control unit 7, and a drawer 8.

CPU1 according to a program stored in ROM2 in advance,
Various processes are performed on sales data and the like from the key input unit 3, the processing results are stored in the RAM 4, displayed on the display unit 5, printed by the printer 6, and transmitted via the transmission control unit 7. Further, the CPU 1 opens the drawer 8 based on an operation of a predetermined key of the key input unit 3.

The key input unit 3 is used for setting (P), registration (R), power supply OF
It has various function keys K2 such as a mode changeover switch SW for switching and setting each mode of F, inspection (X) and settlement (Z), a numeric key K1 and a rental key K2a.

The RAM 4 is provided with a customer-specific lending memory M2 for registering lending contents for each customer, in addition to a totalizer memory M1 such as a product-specific memory that stores the number of sales and the like in a product row.

The storage items of this customer-specific lending memory M2 are also the slave SL,
As shown in Fig. 3, each area stores the total lending amount for today, the total lending amount up to the previous day, and the lending limit amount for one month, as shown in FIG. Are formed. The monthly loan limit is
The amount according to the customer's credit is preset for each customer. Also, the total loan amount up to the previous day is cleared after the end of business on the last day of one month.

In the registration mode, the CPU 1 of the slave SL and the CPU 1 of the master MS add the lending amount to the total lending amount of the customer for today when the lending amount for each customer is input. It is determined whether or not the addition result has exceeded the customer's monthly lending limit for one month, and if so, the fact is displayed on the display unit 5. In this case, the operator asks the customer whether to pay the surplus in cash, or to return any merchandise and trade all by lending, and take appropriate measures. In other words, whether to lend or not is determined in a distributed manner in each electronic register, and the slave SL does not inquire of the master MS whether to lend or not.

When the business day of the master MS is closed and the settlement mode is set, the CPU 1 of the master MS sends the totalizer memory M1 from each slave SL.
And collects the total data of the total number of sales and the like in the customer row, and collects today's total lending amount for each customer in the customer-specific lending memory M2 and executes a predetermined process.

Next, with reference to FIGS. 4 and 5, a detailed description will be given of the processing of collecting the total lending amount in the customer-specific lending memory M2.

As described above, the CPU 1 of the master side MS closes the day, and when the settlement mode is set, first, each slave side
An instruction is sent to the SL via the transmission control unit 7 to transmit today's total loan amount in the order of customer numbers (step S in FIG. 4).
1). Then, in response to the above instruction, the total lending amount for today is transmitted from each slave SL in order of the customer No., and the customer No. including the own lending memory M2 for each customer is transmitted.
Separately, accumulate the total loan amount for today and add the total result to the total loan amount up to the previous day (step S
2).

Next, in order to prepare for the above-mentioned distributed processing on the next day at each slave SL, the above addition result is transmitted to each slave SL as a new total loan amount up to the previous day (step S3).

Then, the user clears his / her total lending amount for today (step 4), and ends.

On the other hand, in response to the above instruction from the master MS, the CPU 1 of the slave SL transmits today's total loan amount to the master MS in order of customer No. (step S11 in FIG. 5).
Then, when the new total amount of lending up to the previous day to be used for the above-mentioned distributed processing is transmitted, the total total amount of lending up to the previous day stored up to that point is cleared, and the new total amount of lending up to the previous day is cleared. Overwrite the total loan amount up to (Step S1
2). Next, the today's total loan amount is cleared (step S13), and the process ends.

As is clear from the above description, the total amount of lending up to the previous day also includes the amount of lending by customer registered in other electronic registers.
The next day, the decision of whether to lend or not can be made in a distributed manner. Therefore, the transmission speed between each electronic register is
High speed is not required.

Note that the present invention is not limited to the above-described embodiment. For example, in addition to the monthly loan limit, for example, a value of 90% of the loan limit may be simultaneously stored in each electronic register. Preset, and when the value exceeds 90% during registration, query the other electronic register to see if the customer's total loan amount is registered for today, and collect it if it is registered It is also possible to determine whether or not the cumulative result exceeds the loan sales limit. in this case,
Reliable management of loan sales limit is possible. Further, since the case where the value exceeds 90% is rare as described above, even if a transmission means having a low transmission speed is employed, there is almost no practical problem.

[Effects of the Invention] According to the present invention, at the time of settlement, the second data processing device collects the credit transaction amount for each customer transmitted from each of the first data processing devices for the same day, and collects the credit transaction volume for each customer. A new accumulated credit transaction is generated, and the generated new accumulated credit transaction for each customer is transmitted to each of the first data processing devices. Each of the first data processing devices transmits the new customer-specific credit transaction. Is updated and stored in its own storage means, and in accordance with the input of the credit transaction volume for each customer, the credit transaction volume is added to the credit transaction volume of the day corresponding to the customer, and the addition result And whether or not the total of the credit transaction volume corresponding to the customer exceeds the credit transaction limit corresponding to the customer, thereby determining whether or not the credit transaction is possible. Whether each of the first and second data processing devices has been called without calling the second data processing device The processing can be performed in a distributed manner by the data processing devices, and there is no need to connect each of the first data processing device and the second data processing device with a high-speed line, thereby reducing line costs.
