Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to product sales data used as a terminal of a POS (point of sale information management) system introduced in a retail store such as a convenience store in which the head office collectively manages each chain store. Regarding a processing device.

[0002]

2. Description of the Related Art In recent years, a POS system in which a POS terminal installed in each chain store is online connected to a host device installed in a head office, and each POS terminal is centrally managed by the host device is a convenience store. Widely used in stores.

Incidentally, the above-mentioned POS terminal usually has a function of accumulating and storing in a memory the data relating to the sales of products inputted in the registration work for each transaction. When the inspection work is selected, the cumulative data for each transaction stored in the memory is printed out on a receipt paper or a journal paper and issued as an inspection report.

Therefore, at a retail store such as a convenience store having the POS system, it is obliged that each chain store prints out the above inspection report at a fixed time every day and informs the headquarters of the contents by telephone or the like.
By doing so, there is an advantage that the head office can analyze the sales situation and the like fairly for each chain store.

[0005]

However, in the conventional POS terminal of this type, when the inspection report is printed out, it is necessary to suspend the registration work and select the inspection work. The person had to handle the inspection work in anticipation of the absence of customers. Therefore, it is not always possible to always obtain the transaction-specific cumulative data of each chain store at the same time depending on the congestion level of customers. In addition, it often happened that the time of inspection was forgotten and necessary data could not be collected.

Therefore, according to the present invention, the transaction-specific cumulative data stored in the memory is automatically secured at a fixed time, and the secured transaction-specific cumulative data is automatically transmitted to the host device. An object of the present invention is to provide a product sales data processing device capable of constantly collecting cumulative data for each transaction at a fixed time without interrupting the registration work and without the operator's hand.

[0007]

SUMMARY OF THE INVENTION The present invention is a product sales data processing apparatus which is connected to a host device via a communication line and cumulatively stores, in a memory, data relating to sales of products input in registration operations for each transaction. An external storage device, and transaction-specific data writing means for writing the transaction-specific cumulative data stored in the memory at fixed time intervals to the external storage device,
Transaction-specific data transmitting means for transmitting the transaction-specific cumulative data written in the external storage device to the host device in response to a collection command from the host device.

[0008]

According to the present invention having such a configuration, data relating to sales of products input in the registration work is cumulatively stored for each transaction in the memory. And at a fixed time,
The cumulative data for each transaction stored in the memory is automatically written to the external storage device. Then, when there is a collection command from the host device, the data written in the external storage device, that is, the cumulative data for each transaction at a fixed time, is automatically transmitted to the host device via the communication line. Therefore, the host device can reliably collect the accumulated data for each transaction at a fixed time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram. A ROM (a CPU (central processing unit) 10 which constitutes a main body of a control unit stores program data and the like for the CPU 11 to control each unit via a bus line 11 ( A read only memory) 12 and a RAM (random access memory) 13 in which various memory areas for storing data processed by the CPU 11 are formed are connected.

A clock circuit 1 for measuring date and time
4. The signal of the mode switch 15 for switching various business modes such as “registration”, “inspection”, “payment”, “setting”, etc. is input, and the opening drive signal is output to the drawer 16 for storing cash etc. An I / O port 17, a communication interface 18 for controlling data transmission / reception with a host device (not shown) connected via a communication line,
A keyboard controller 20 to which a key signal corresponding to an input key is input from the keyboard 19, a display controller 22 that drives and controls a display device 21 to display characters and the like corresponding to display data, and a printer 23 that drives and controls print data. Each part such as a printer controller 24 for printing corresponding characters on receipts and journal sheets, an HDD (hard disk) interface 26 for controlling writing and reading of data to and from a hard disk device 25 as an external storage device is the bus line. It is connected to the CPU 10 via 11.

The keyboard 19 is provided with function keys such as a numeral key, a department key, a subtotal key, a current total key (tightening key) and a clear key, which are used in various businesses. The display unit 19 is an electronic display for displaying the price of the merchandise registered for sale, the total price of the customer, and the like, and is provided with two types, one for the operator and one for the customer.

The RAM 13 has a work buffer 13a for temporarily storing data, as shown in FIG.
And a transaction-specific memory 13 for accumulatively storing, for each transaction, data relating to sales of products, etc. input in the registration work.
b is provided.

Incidentally, the transaction-specific memory 13b accumulates data for each transaction such as normal sales, special sales, discount totals, taxable totals, tax-exempt totals, current sales, coupon sales, and the number of cancellations.

Therefore, the CPU 13 is programmed so as to execute the processing shown in FIGS. 3A and 3B, in particular, when the registered work is selected by the mode switch 15.

That is, for example, when a timer interrupt occurs at 1-hour intervals, the processing shown in FIG. 3A is started. First, the current time is read from the clock circuit 14. When the current time coincides with the preset inspection time, the contents of the transaction-specific memory 13b are written into the transmission file of the hard disk device 25 (transaction-specific data writing means). The above processing is not performed at times other than the inspection time.

Further, for example, when a timer interrupt occurs at 1-minute intervals, the processing shown in FIG. 3B is started. First, the communication interface 18 is controlled to determine whether a data collection command from the host device is received. Then, if received, the contents of the transaction-specific memory 13b written in the transmission file of the hard disk device 25 are read and transmitted to the host device via the communication line (transaction-specific data transmitting means). ). Thereafter, the transmitted data written in the transmission file of the hard disk device 25 is deleted. If the data collection command has not been received, the above processing is not performed.

In this embodiment having such a configuration, when data relating to sales of merchandise is input by key input on the keyboard 19 while the registration operation is selected by the mode switch 15, the data is classified by transaction. Memory 1
Cumulatively stored for each transaction in 3b.

In this state, when the current time measured by the clock circuit 14 reaches the preset inspection time (for example, 2:00 pm), the cumulative data for each transaction stored in the transaction memory 13b. Is automatically written in the transmission file of the hard disk device 25.

Then, when a data collection command is received from the host device, the data written in the transmission file of the hard disk device 25, that is, the cumulative data for each transaction at the inspection time, is automatically transmitted through the communication line. Sent to the host device. Then, the transmitted data is deleted from the transmission file of the hard disk device 25.

As described above, according to this embodiment, it is possible to surely secure the cumulative data for each transaction at the preset inspection time on the hard disk device 25. Moreover, the accumulated data for each transaction at the secured inspection time is automatically transmitted to the host device in response to the collection command from the host device.

Therefore, since it is not necessary to suspend the registration work and print out the inspection report, it is possible to always obtain the transaction-specific cumulative data at a fixed time without causing any trouble to the customer. Further, since no special operation for acquiring the transaction-specific cumulative data is required and the omission of the acquisition cannot occur, the burden on the operator is greatly reduced.

Although the hard disk device is shown as the external storage device in the above embodiment, a floppy disk device or the like can be used. Of course, various modifications can be made without departing from the scope of the present invention.
