Description

Detailed Description of the Invention (a) Technical Field of the Invention The present invention relates to a data processing device in a POS system.

(b) Prior art and problems At mass retailers that have introduced POS systems, terminals are installed at checkout offices, but input devices and When a terminal device has a file device, an output device, a main memory, a processing section, and a control section, the data (input data, processing data, etc.) in the terminal device is output several times a day. "Inspect" this
For example, it is carried out twice in the morning and twice in the afternoon. The purpose of this is to print out the data handled by the terminal at each inspection point, so that if an abnormality occurs in the terminal, the point at which the abnormality occurred can be clarified. Furthermore, the file is protected (SAVE) by temporally dividing and outputting the data in the file. If a customer appears at the checkout office during such inspection work, conventional terminals have the drawback of making the customer wait until the output work for the inspection is completed.

(c) Purpose of the Invention The present invention was made to solve the above-mentioned drawbacks, and its purpose is to provide a terminal device that improves customer service.

(d) Structure of the Invention The present invention connects a file device, an output device, and an input device equipped with a data input key and an instruction key for inputting an instruction signal, and activates an input/output processing means and a plurality of processing means. management means for managing the control;
In a data processing device comprising an input/output control section that receives an input signal from the input device and notifies the management means, a signal is input that instructs to stop outputting data from the file device to the output device. A control key is provided on the input device to stop the output processing means during the output operation, and an output stop command from the control key is notified to the management means via the control unit and the file is When data output from the device is in operation, the management means activates the stop means to stop data output from the file device, thereby controlling to allow data input from the input device. This is a data processing device characterized by the following. Conventional POS terminals were unable to input data from transactions with customers while outputting predetermined data from a file during "inspection." The present invention provides an input device with a stop key for stopping the "inspection" operation, and when it becomes necessary to conduct a transaction with a customer, by pressing the stop key, the output operation is immediately stopped, and the keyboard It is designed to allow data input from.

(e) Examples of the invention The present invention will be explained below with reference to the drawings. FIG. 1 is a block diagram illustrating one embodiment of the present invention.

In FIG. 1, when conducting a transaction with a customer, the operator presses the data key 2 of the input device (keyboard) 1.
After inputting the input data (amount, quantity) D from , press the total key 3. The total signal T and input data D thus generated are sent to the control section 4.

Note that the task group (M, A ₁ ,
An, I ₁ , I _{2 ,} etc.) are executed by the processing unit 6, and the input data D is stored in the register R ₁ by execution of the input control task I ₁ . Furthermore, the management task M manages the execution (starting/stopping) of these task groups. Next, an input check task _I2 is activated, which checks whether the input data D in the register _R1 is in a predetermined format. If input data D is normal, input control task
_I1 is activated again, and then application tasks _A1 to An are activated, and necessary processing (such as summation processing) is performed on the input data D of register _R1 .

The obtained processed data D' is stored in the file F of the file device 7. Next, by executing the output editing task E and the output task B, the processed data D' is printed out on the receipt 9 from the printer 8.

As described above, data D' from transactions with customers is stored in file F. When the operator inputs the SAVE command S from the data key 2 of the input device 1 during "inspection", the management task M starts the output editing task E and the output task B, and outputs the data of the file F from the printer 8 to the paper 10. urge

Note that during this output, input from the data key 2 of the input device 1 is prohibited.

During the output during this "inspection", when it becomes necessary to input from the data key 2, that is, when inputting the input data D from the transaction with the customer, the operator presses the stop key 11 of the input device 1. The management task M identifies the abort data Q input by pressing this button, executes the input control task _I1 , stores it in the register _R2 of the main memory 5, and then executes the input check task _I2 to remove the abort data Q.
Performs a format check and determines it as an output stop command. After the determination process is completed, the management task M starts the abort task P, and the abort task P stops execution of the output editing task E and the output task B. By this procedure, the output processing of the data sent from the file device 7 to the output section 8 through the control section 4 and printed out is stopped.

Subsequently, the management task M causes the input control task _I1 to be executed, and the inhibition of input from the data key 2 of the input device 1 to the register _R1 is lifted.

(f) Effects of the Invention As described above, the present invention allows the output operation to be stopped when a transaction with a customer becomes necessary even during an inspection operation in which file data in a data processing device is saved. This has the advantage of not making customers wait and improving the operational efficiency of the system. Note that FIG. 2 is a flowchart explaining the above operation.
