2. Description of the Related Art Generally, an external storage device is connected to an information processing device as a part of a memory of an input / output device. Conventionally, an external storage device of this type synthesizes screen data and input data. There was no way to store it, and it was created manually as shown in the flowchart of FIG.

That is, as shown in the flow chart of FIG. 4, the data input by the key is manually code-converted and displayed on the screen, and further the code is manually converted to synthesize the converted code, and the synthesized data is obtained. Was registered as.

[0004]

As described above, conventionally, it is necessary to actually perform the operation to save the input data and synthesize the screen data. Moreover, when the synthesized data has an error, Took a lot of time to fix, and had to do some conversion to the code used internally by the hardware for key operations.

The present invention solves such a problem, and an object of the present invention is to provide an apparatus capable of inputting and outputting information defined by software operated by an information processing apparatus without human intervention.

[0006]

According to the present invention, an input / output connected to an information processing device having an external storage device, a central processing unit, a control device, and an internal storage device, an input device, and a screen output device is provided. In the control device, an input data processing unit that converts input data from the input device into an internal code of the information processing device, and a combined data processing unit that combines input data and screen data based on the converted internal code. And a screen data processing unit for converting the internal code into screen data and converting the screen data into the internal code.

The composite data processing unit includes means for transmitting and receiving composite data to and from the central processing unit and the internal storage device, and the screen data processing unit displays the image data on the screen output device. It is desirable to include.

[0008]

The data input from the keyboard of the input device is converted into a code inside the information processing device by the input data processing unit, and the combined data processing unit combines the converted data and the data to be output to the screen output device, Output from the internal storage device 7 to the external storage device via the control device. The combined data output from the external storage device operates as if the operation was actually performed in the central processing unit and is displayed on the screen display device.

With this, the data to be input and displayed on the screen can be converted into the internal code used in the information processing apparatus and stored in the external storage device without human intervention, and the work which does not cause an error in a short time can be performed. It can be carried out.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the embodiment of the present invention.

The embodiment of the present invention includes an external storage device 9,
It is connected to an information processing device 10 having a central processing unit 6, a control device 8 and an internal storage device 7, an input device 1 and a screen output device 5, and inputs data from the input device 1 to an internal code of the information processing device 10. An input data processing unit 2 for converting the input data to the screen data, a combined data processing unit 3 for combining the input data and the screen data based on the converted internal code, an internal code to the screen data, and the screen data to the internal code. The screen data processing unit 4 includes a unit for transmitting and receiving composite data to and from the central processing unit 6 and the internal storage unit 7, and the screen data processing unit 4 outputs the screen output. The device 5 includes means for displaying image data.

Next, the operation of the embodiment of the present invention thus constructed will be described.

First, the operation in the case of composite data output will be described. Input data from the input device 1 is sent to the input data processing unit 2, converted into an internal code, and sent to the combined data processing unit 3. The combined data processing unit 3 converts the converted internal code into the central processing unit 6 and the screen data processing unit 4.
To send to. The screen data processing unit 4 converts the sent internal code into screen data and outputs it to the screen output device 5.

The central processing unit 6 processes according to the contents of the internal code and sends the screen output data to the composite data processing unit 3. In this way, the input / output data is combined and sent to the internal storage device 7. The data accumulated in the internal storage device 7 is stored in the external storage device 9 via the control device 8.

That is, as shown in the flow chart of FIG. 2, the input data keyed from the input device 1 is converted into an internal code by the input data processing unit 2, and then the input data and screen data are converted by the composite data processing unit 3. And are combined and sent to the central processing unit 6 and the internal storage device 7.

The central processing unit 6 carries out an arithmetic processing of the composite data, judges whether or not the processing is completed, and if the processing is completed, the CPU 8 writes the data in the external storage device 9 through the control apparatus 8 and ends the processing. If it is not finished, determine whether there is display data,
If there is no display data, the process is returned to the original state, and if there is display data, it is sent to the central processing unit 6.

The central processing unit 6 inputs the display data to the external storage unit 9 via the control unit 8 and performs arithmetic processing, and sends the arithmetic result to the composite data processing unit 3.
The combined data processing unit 3 performs a combining process and sends the combined data to the screen data processing unit 4, and the screen data processing unit 4 converts it into an internal code and displays it on the screen output device 5.

Next, the operation in the case of inputting synthetic data will be described. The synthetic data called from the input device 1 is transferred from the external storage device 9 to the control device 8 and the central processing unit 6.
The process is similar to the process when a key is input via. This combined data is further sent from the internal storage device 7 to the combined data processing unit 3 and further to the screen data processing unit 4. The screen data processing unit 4 converts the combined data into screen data and outputs the screen data to the screen output device 5.

FIG. 3 is a flow chart showing the flow of this synthetic data input processing. The input data processing unit 2 converts the internal code by a key input from the input device 1,
It is sent to the central processing unit 6 via the combined data processing unit 3. The central processing unit 6 determines whether to perform the combining process, and when it is determined to perform the combining process, the combined data processing unit 3 performs the combining process and ends the process.

When it is determined that the combining process is not performed, the combined data is read from the external storage device 9,
It is sent to the internal storage device 7. Then perform the arithmetic processing,
The calculation result is sent to the screen data processing unit. The screen data processing unit 4 converts the screen data and displays it on the screen output device 5. The central processing unit 6 determines whether or not all the processing is completed, and if not completed, repeats the processing.

By repeating the processing as described above, it is possible to automatically store or withdraw the data for key operation and screen display in the external storage device 9.

[0022]

As described above, according to the present invention, it is possible to convert data that is input and displayed on a screen into an internal code used in an information processing device without human intervention and store it in an external storage device. Moreover, there is an effect that the data stored in the external storage device can be retrieved, and the error-free work can be performed in a short time.
