Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a PO8 terminal device connected online to a center-side device installed at a center, such as a hotel, department store, or supermarket.

FIG. 1 shows a typical configuration of an existing PO8 terminal device.

In the figure, 1 is a keyboard for inputting data, 2 is an arithmetic control circuit, 3 is a display device, and 4 is a data transmission line 5.
6 is a storage circuit that stores the data transmitted to the center side device, and 7 is a printer connected to this storage circuit that prints out the stored contents. be.

In the PO8 terminal device having such a configuration, input data from the keyboard 1 is processed by the arithmetic control circuit 2 and sent to the display circuit 3.
After the transmission is completed, the signal is stored in the storage circuit 6 by the arithmetic control circuit 2 and printed out by the printer 7.

At this time, if you want to print out the sales subtotal for each department on a receipt or journal, you can calculate the sales subtotal for each department in advance when registering from keyboard 1, and then register the calculated value from keyboard 1. This is good, but it requires calculating subtotals for each department at some point, which is not practical.

In particular, POs that must issue receipts to hand to customers
With the 8-terminal device, sales subtotals require subtotals for each department, and calculating subtotals for each department each time sales registration occurs is burdensome for the operator, increases processing time, and is prone to errors. This would be a major hindrance in terms of operation and system.

The present invention provides a device which completely overcomes the above drawbacks by adding simple circuitry.

FIG. 2 shows the configuration of the PO8 terminal device of the present invention.

In the same figure, 1 to 7 are keyboards as in Figure 1,...
- This shows a printer, and the main feature of the present invention is the address designation of the memory circuit 6.

That is, the keyboard 1 has a department key 1 that specifies the department of the sales item, such as food or drinks.
1 and numeric keys 12 for inputting the amount,
The department key 11 is provided with an encode address circuit 8 that generates a predetermined address for each department.

Further, the printer 7 is provided with a count address circuit 9 that generates an address advanced by 1 from the address where the print data was stored in response to a print operation. The address is applied to the address terminal of the memory circuit 6 via an address switching circuit 10 that switches according to a command from the arithmetic control circuit 2.

When the keyboard 1 is operated to register departmental sales without calculating subtotals for each department, the input data is processed by the arithmetic control circuit 2 and displayed by the display circuit 3 in the same way as in the conventional PO8 terminal device. and a signal to the transmission circuit 4, and after the data transmission is completed, it is stored in the memory circuit 6 by the arithmetic control circuit 2. At this time, the signal from the department key 11 of the keyboard 1 is also input to the encode address circuit 8. Then, the address circuit 8 generates an address signal corresponding to the department key 11, and this address signal is inputted to the address line of the storage circuit 6 through the address switching circuit 10.

Therefore, sales registered from the department key 11 will be stored in a specific area in the memory circuit 6 corresponding to the department key 11 at that time.
When sales are registered more than once, the arithmetic and control circuit 2 adds or subtracts the newly registered sales to the contents of the memory circuit 6, and the areas in the memory circuit 6 contain information for each department corresponding to each department key 11. The subtotal will be memorized.

The sales information is stored in the storage circuit 6 and simultaneously printed out by the printer 7, and recorded as a journal as shown in the upper half of FIG.

On the other hand, when it becomes necessary to issue a receipt to a customer, the user operates the receipt issuing key on the keyboard 1; therefore, a memory circuit 6 is introduced in which the subtotal amount for each department is stored.
The first address of is encoded into the memory circuit 6 by the encode address circuit 8.
, is applied via the address switching circuit 10, and depending on the address, the subtotal of the first department located at the first address of the memory circuit 6 is read out and printed out by the printer 7.

In response to this print operation, the count address circuit 9 generates an address that is one address ahead of the first address, supplies that address to the memory circuit 6 via the address switching circuit 10, and then selects the next address stored at the next address. 5. Read out and print out the subtotals for the departments.

Thereafter, the subtotals for each department are printed out one after another, and the subtotals for each department are printed to complete a receipt as shown in the lower half of FIG.

Incidentally, the tax and service charge sections at the bottom of the receipt are automatically calculated and printed by the memory circuit 6 and the arithmetic control circuit 2 when all copies have been printed out.

As is clear from the above description, when inputting data from a keyboard, the present invention accumulates the data by department in the storage circuit, simultaneously prints out the data as a journal using a printer, and when issuing a receipt, stores the data in the storage circuit by department. Since the separately stored totalization data is printed out as a receipt, when a receipt needs to be issued, the subtotal for each department can be obtained by simply issuing a command to issue a receipt using the keyboard, without having to calculate each department as in the past. The PO8 terminal device can be easily operated and errors in operation can be eliminated.

Furthermore, since the sales details of each department are recorded in a journal before the receipt is issued, confirmation is easy, and the benefits that the present invention brings to this industry are enormous.

The figure is a printout diagram showing an example of printout by the apparatus of the present invention, in which 2 shows an arithmetic control circuit, 6 a memory circuit, T a printer, 8 an encode address circuit, and 9 a count address circuit. There is.

[Claims] 1 PO8 connected to the center side device via a transmission line
The terminal device includes a keyboard consisting of at least department keys and numeric keys for sales items, a display device for displaying input data from the keyboard, and a display device for transmitting the input data to the center side via a transmission line. It consists of a transmission circuit, a memory circuit that stores data, a printer that prints out the stored contents of this memory circuit, and an arithmetic control circuit that performs calculations on input data. an encode address circuit that generates an address that specifies the address of the memory circuit in response to a print operation of the printer, a count address circuit that generates an address in response to the printing operation of the printer, and an encode address circuit that generates an address in response to a command from the arithmetic control circuit. , or an address switching circuit that switches which address of the count address circuit is introduced into the storage circuit, and when data is input from the keyboard, the data is transmitted in accordance with the data input. At the same time, the address switching circuit enables the address from the encode address circuit to be introduced into the memory circuit, and at the same time the address is introduced into the memory circuit and stored so as to be accumulated for each department. A PO system characterized in that the data is printed out as a journal by a printer, and when a receipt is issued, the address switching circuit enables the address from the count address circuit to be introduced into the storage circuit, and the receipt is printed out.
