Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information input/output method in an information processing apparatus that outputs input contents or calculation results for input contents.

In this type of information processing apparatus, when outputting inputted contents or calculation results thereof, generally both inputting and outputting are performed as one task. For this reason, for example, if the output device becomes inoperable for some reason, input is no longer possible, and business operations are delayed until the cause of the inoperability of the output device is removed, resulting in a drawback of causing great loss to the user.

The present invention has been made in view of the above circumstances, and its purpose is to enable input work and output work to be performed separately and independently, so that input work can be continued even in the event of a malfunction of the output device, and the user business suffers significant losses. The objective is to provide an information input/output method that can prevent such problems.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the configuration of an information processing device, such as a business computer, to which the present invention is applied, and 11 is an input device such as a keyboard. 1
2 is an arithmetic processing module, and 13 is a storage device such as a magnetic disk device. Arithmetic processing module 1
2 performs calculations based on the input contents from the input device 11, and sequentially stores the calculation results or input contents in the storage device 13. The storage device 13 includes a data storage area (not shown) for storing calculation results and the like provided from the calculation processing module 12, and an index unit (hereinafter referred to as INX) 14.
This INX section 14 is for indicating storage position information of data to be output by an output processing module, which will be described later. As shown in FIG. 2, two types of flags F _A and F _B are set. In this embodiment, the arithmetic processing module 12 sets the flag F _A of the record each time data for a record is stored in the storage device 13. Similarly, the arithmetic processing module 12 sets the flag F _B of the corresponding record when instructing to re-output the data that has been output.

15 is an output processing module, 16 is an output device such as a printer, and 17 is a re-output instruction register in which re-output instruction information is set. The output processing module 15 retrieves the data from the storage device 13, edits it appropriately (for example, as applied to a ticket), and outputs it to the output device 16. In this embodiment, in the normal state, the output processing module 15 retrieves the corresponding record based on the set state of the flag F _A of the INX section 14 of the storage device 13.
When re-output instruction information is set in the re-output instruction register 17 by the arithmetic processing module 12, the corresponding record is retrieved based on the set state of the flag F _B of the INX unit 14. Furthermore, after retrieving the record, the output processing module 15 sets the flag F _A corresponding to the record.
Or reset flag F _B.

Next, the operation of one embodiment of the present invention will be explained with appropriate reference to the flowchart of FIG. The arithmetic processing module 12 inputs the input device 1 by operator operation, etc.
When data is input from 1, an operation is performed based on this input data, and the operation result and input data are sequentially stored in the storage device 13, starting from record #1, for example. When the arithmetic processing module 12 finishes storing data in the #1 record, it sets the flag F _A corresponding to the #1 record in the INX unit 14. After that, the arithmetic processing module 12 starts storing data in the #12 record. As long as data input from the input device 11 continues, the arithmetic processing module 12 executes the above-described processing while sequentially changing the target record.

As shown in the flowchart of FIG. 3, the output processing module 15 determines whether there is a re-output instruction every time it finishes outputting data for one record. This is done depending on whether re-output instruction information (for example, logic "1" information) is set in the re-output instruction register 17. If there is no re-output instruction, the output processing module 15
Refer to the flag F _A corresponding to the record next to the last output record in the INX section 14 (#1 record in the case of start), and check whether there is output data based on the state of this flag F _A. Make a judgment. If the flag F _A is set, the output processing module 15 determines that there is output data, takes out the contents of the corresponding record from the storage device 13, performs appropriate editing, and outputs it to the output device 16. Next, the output processing module 15 sets the flag F _A in the INX unit 14 corresponding to this output record.
and returns to the process of determining whether there is a re-output instruction. As is clear from this operational description, according to this embodiment, the output processing by the output processing module 15 and the processing of input data by the arithmetic processing module 12 are performed separately and independently.
Therefore, even if a malfunction occurs on the output side, such as the output device 16, the input work can be continued, and the work efficiency can be improved for the user.
Then, when the problem on the output side is resolved, the output processing module 15 transfers the INX section 1 of the storage device 13
4 (each flag F _A ),
It is possible to know the storage state of data and resume correct output operation.

By the way, there are cases where it is desired to cause the output device 16 to output again the contents that have already been output. In such a case, the arithmetic processing module 12 sets the flag F _B in the INX section 14 corresponding to the record to be re-outputted, and also sets re-output instruction information (for example, logic "1" information) in the re-output instruction register 17. Set. This is done, for example, by instructing the arithmetic processing module 12 from the input device 11 through an operator operation. When the output processing module 15 detects that re-output instruction information has been set in the re-output instruction register 17, it determines that a re-output instruction has been issued, and all corresponding records #1 to #n in the INX section 14 are processed. Refer to the flag F _B. The output processing module 15 again retrieves the contents of the record corresponding to the flag F _B in the set state from the storage device 13 and edits/outputs it to the output device 16. Then, the output processing module 15 resets the flag F _B in the INX unit 14 corresponding to this re-output record, and also resets the re-output instruction register 17. As described above, according to this embodiment, although the input work and the output work can be performed separately and independently, data can be re-outputted reliably as needed. Furthermore, in this embodiment, data to be re-output is not recognized by periodically referring to all the flags F _B corresponding to records #1 to #n in the INX unit 14; An output instruction register 17 is provided, and only when re-output instruction information is set in this re-output register 17, data to be re-output is recognized by referring to all of the above flags F _B. There is no risk of slowing down the processing speed.

In addition, in the above example, the record to be output is
The case where instructions are given using the flags F _A and F _B of the INX unit 14 has been described, but a first area for new data output instructions and a second area for re-output instructions are provided in the storage device 13. Each time a record's worth of data is written, the corresponding record name (or address, etc.) is registered in the first area, and if re-output is required, the corresponding record name (or address, etc.) is registered in the second area. It can also be implemented in the same way.

Further, in the above embodiment, the number of arithmetic processing modules is 1.
Although the case of a plurality of inputs has been described, for example, by providing a plurality of arithmetic processing modules and controlling these modules simultaneously, processing can also be performed on a plurality of inputs. Further, when the input speed is faster than the output speed, by providing a plurality of output processing modules, the contents input one after another can be outputted alternately to a plurality of output devices, thereby improving throughput.

Note that the input device 11 is not limited to a keyboard, and includes, for example, a card reader, a barcode reader, an online line, and the like. Similarly, the output device 16 includes not only a printer but also a display device, a paper tape puncher, an online line, and the like.

As detailed above, according to the information input/output method of the present invention, input work and output work can be performed separately and independently, so input work can be continued even when an output device malfunctions, improving the efficiency of user work. can be achieved.
