Abstract

PURPOSE:To reduce the entire amount of communication and the burden of an external device such as a host computer, etc., by preventing key data without necessitating a process at outside from being transmitted to the outside. CONSTITUTION:When the key data are inputted by a keyboard 4, except the key data stored in a process procedure storage means 18, the key data is trans mitted to outside, and in accordance with it, process information received from outside is applied to output means 6 and 7. Meanwhile, when the key data stored in the process procedure storage means 18 are inputted, the output means 6 and 7 are operated corresponding to the process procedure based on the key data. Therefore, the key data without necessitating the process at outside are not transmitted to the outside. Thus, the entire amount of communication can be reduced, and also, the burden of the external device such as host computer 1, etc., can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a product sales data processing device such as a PO5 (Point of Sales) terminal. Specifically, the present invention relates to a product sales data processing device that transmits key data input from a keyboard to the outside, and in response, provides processing information received from the outside to an output means to execute processing.

[Prior art 1] In recent years, some POS systems transmit all key data entered from the keyboard of each PO8 terminal to a hot computer and respond to it in order to reduce the price of each Posa terminal itself. As a result, systems are being adopted in which commands sent from a host computer are given to an output device such as a display or printer to execute processing.

That is, as shown in FIG. 5, each PO8 terminal 3, -3. of,
A keyboard 4, a display 5, a printer 6 for printing on receipts and journals, a drawer 7, and other output devices, and when a key is input on the keyboard 4, the key data is sent to the host computer 1 through a communication line 2. and #l from the communication control unit 8 which, when receiving a command from the host computer 1 in response, gives the command to the output device to execute the process.

Therefore, the communication control unit 8 is configured as a function that simply controls communication. In other words, each pos @ terminal 3
As a result of using 1 to 3 terminals as terminals without intelligence, it is not necessary to have a processing program based on key data for each PO8 terminal 31 to 3 degrees, and
Since the hardware configuration can be simplified, each PO8 terminal 3.
We were able to lower the price of ~3° itself.

[Problem to be solved by the invention] However, in the system shown in Fig. 5, each PO8 terminal 3
Since all the key data entered from the keyboards 1 to 3 are sent to the host computer 1, even data that is originally not related to the processing of the host computer 1, that is, data that does not need to be processed, is also sent. That will happen.

Now, as shown in Figure 6, one of the posf4A end 3
1-3. The keyboard 4 of the computer stores data completely unrelated to the processing of the host computer 1, such as the printer 6.
If the feed key for feeding the paper is pressed, the data shown in (2) in FIG. 7 is sent from the keyboard 4 to the communication control unit 8.

Based on this, the communication system m unit 8 transmits the data (■) in FIG. 4 to be sent to the communication control unit 8 through
The communication control section 8 receives this and supplies the data (■) in FIG. 7 to the printer 6 to execute the command.

Among these data flows, the communication line 2 will be used for data ① and ②. Therefore, p
As the number of oss terminals 31 to 33 increases, the amount of communication @2
It will be crowded. Moreover, host computer 1
In this case, it is necessary to convert the data (2) sent from the communication control section 8 into the data (2) and send it to the communication control section 8, so there is a problem that the response time becomes longer.

The purpose of the present invention is to solve these conventional problems, eliminate communication regarding key data that does not need to be processed externally, and reduce the burden on external devices such as host computers. An object of the present invention is to provide a data processing device.

[Means for Solving the Problems] Therefore, the present invention includes a keyboard, an output means, and when there is a key input on the keyboard, transmits the key data to the outside, and 5. Processes it from the outside in response to the key input. In the product sales data processing device, the communication control unit provides processing information to the output means when information is received, and the communication control unit is configured to process key data that does not need to be processed externally based on the key data. A processing procedure storage means for storing a processing procedure; and processing means for operating the output means in accordance with a processing procedure based on the key data when key data stored in the processing procedure storage means is input from the keyboard. , is characterized by.

[Function] When key data other than the key data stored in the processing procedure storage means is input on the keyboard, the key data is transmitted to the outside, and in response, the processing information received from the outside or the output means is transmitted. given to. On the other hand, if key data stored in the processing procedure storage means is input, the output means is operated according to the processing procedure based on the key data.

Therefore, since key data that does not need to be processed externally is not transmitted to the outside, the overall amount of communication can be reduced, and the burden on external devices such as the host computer can be reduced.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. In explaining these figures, the same components as those in FIG. 5 described above are designated by the same reference numerals, and the explanation thereof will be omitted.

FIG. 1 shows the PO8 terminal 3. The circuit configuration is shown.

The communication control unit 8 in this solid line example connects the CPU II and this CPU.
Transmission interfaces 13 to 17, ROM 18 and RA connected to 11 via address/data bus 12
It is composed of M19.

Here, the transmission interface 13 is the communication port 1
It is connected to the host computer 1 through 12. Further, the keyboard 4 is connected to the transmission interface 14, the display 5 is connected to the transmission interface 15, the printer 6 is connected to the transmission interface 16, and the drawer 7 is connected to the transmission interface 17. ing.

As shown in FIG. 2, the keyboard 4 has keys from "0" to "
Number key 21 up to "9", department key 22 from "01" to "08", subtotal key 23, current total key 24, clear key 25, receipt feed key 26, journal feed-1r-27, deposit key 28 , a payment key 29, an exchange key 30, and a # key 31.

The ROM 18 stores key data that does not need to be processed by the host computer 1, such as a clear key 25, a receipt feed key 26, and a journal feed key 27.
, a processing procedure program that stores processing procedures based on key data such as the exchange key 30 and # key 31 is stored, and when other key data is input, the key data is transferred to the host computer. A communication control program is stored therein for transmitting the processing information to the host computer 1 and providing the processing information to the output means when processing information is received from the host computer 1 in response or separately. Here, the ROM 18 constitutes a processing procedure storage means.

As shown in FIG. 3, the RAM 19 stores a transmission identification code corresponding to each key 21 to 31 of the keyboard 4 to identify whether or not the key data is to be transmitted to the host computer 1. An identification table 41 is also provided. Here, it means that the transmission identification code is not transmitted when it is "0", and that it is transmitted when it is "1".

The CPU 1 executes the process of the flowchart shown in FIG. 4 according to the program stored in the ROM 18. Here, the CPU II constitutes processing means that operates the output means in accordance with the processing procedure based on the key data stored in the processing procedure program of the ROM 18 when inputted from the keyboard 4.

Next, the operation of this solid line example will be explained with reference to the flowchart of FIG.

As shown in the flowchart of FIG. 4, the CPU II checks the presence or absence of data received from the host computer 1 and the presence or absence of key input from the keyboard 4 in steps (hereinafter abbreviated as ST) 1 and ST2. There is.

When the STI recognizes that there is data received from the host computer 1, it proceeds to 5TII and checks whether the received data or display data is present.If it is 0 display data, it proceeds to 5T12 and sends the display data to the display 5. Forward. Then, the display device 5 displays the transferred display data. Also, if it is not received data or display data, 5
Proceeding to T13, it is checked whether the data is received data or print data. If it is print data, the process advances to 5T14 and the print data is transferred to the printer 6. Then, the printer 6 prints the transferred print data on a receipt and a journal. Note that if the data is not print data, the process proceeds to other processes.

On the other hand, in ST2, when it is recognized that there has been a key input from the keyboard 4, the process proceeds to ST21 and the transmission identification code of the corresponding key is "l" from the transmission identification table 41.
”.If the transmission identification code of the key is “1”, the process advances to 5T22 and the process based on that key is executed.In other words, the clear key 25 shown in FIG.
, receipt feed key 26, journal feed key 27, exchange key 30, and # key 31, processing based on these keys is executed. For example, if the sheet feed key 26 is used, the receipt from the printer 6 is fed. If the transmission identification code of the key is not "1", that is, if it is "0", the process advances to 5T23 and the key data is sent to the host computer via the communication line 2.
Send to.

Therefore, according to this embodiment, each key 21 of the keyboard 4
A transmission identification table 41 is provided which stores a transmission identification code for identifying whether or not the key data is to be transmitted to the host computer 1 in correspondence with . 41, the transmission identification code of the corresponding key is "1", and when the transmission identification code is "1'", the process based on that key is executed. Since key data that does not need to be processed is not sent to the host computer 1, the overall amount of communication can be reduced. Therefore,
Since the congestion on the communication line 2 and the burden on the host computer 1 can be reduced, the response time can also be shortened.

In the above-mentioned actual tumor example, whether or not the key data is to be transmitted to the host computer 1 is checked using the transmission identification table 41, or whether or not the key data is to be transmitted to the host computer 1 is programmed in the ROM 18. If it is, the transmission identification table 41 does not need to be provided.

[Effects of the Invention] As described above, according to the present invention, key data that does not need to be processed externally is not sent to the outside, so it is possible to reduce the overall amount of communication, and it is also possible to It is possible to reduce the burden on external devices.
