As mentioned above, in this embodiment, the data input device! l
3. Keyboard, barcode reader,
In addition, a magnetic card reader is assumed, and the entire system is assumed to be a POS using a microcomputer.

Therefore, if data is now input from any of the data input devices 511 to 513, the data input control section 4 stores the number of the data input device that generated the data at this time in the temporary storage section 12. The sequence number is stored in the sequence number generator 5, and the sequence number is retrieved from the sequence number generator 5, as shown in FIG.
It is indicated by data stored in the pointer storage section 8 of the sequence number storage section 7. The sequence number that matches the data input device number at this time is stored in the data end position pointer 14-4 of the storage unit, and this pointer 14-4 is thereby stored.

Next, the extraction of data input in this way will be explained.

When there is a data read request, the input data is retrieved, part 10.
operates the input data order determining unit 9.

According to No. 29, first, the input data presence/absence storage unit 11:
Each storage section 6-1 to 6-3 of the data/status storage section 6
For each data input device with data remaining, check whether there is any data left or not, and check the sequence number set in the corresponding storage unit 7-1 to 7-3 of the sequence number storage unit 7 for the data input device for which data remains. The order of the data is checked from the beginning of the storage position, and the number of the data input device is stored in the temporary storage section 12, and the presence of data is stored in the data presence/absence storage section 11. Then, - after this, the input data retrieval unit lO reads data from the corresponding storage units 6-1 to 6-1 of the data/status storage unit 6 according to the data in the storage unit 11 while maintaining the order. I will do it.

Regarding the order of data according to the above embodiments.

This will be explained with reference to FIG.

First, FIG. 3(a) shows data input tables w11 to . This shows an example of data input from 3, respectively.

The data input table W11 is a hexadecimal data output type, the data input device 12 is a character data output type consisting of one character, and the data input device i! 3 is a case of character string data output type, from data input table W2.

First, one character of data ``21N'' and ``par8'''' is read in sequence, then hexadecimal data 14 is read from data input device ll, and then data ``5'' is read from data input device 1 again.
'' indicates a state in which character string data ``212'''cg is further read from the data input device 13.

．． 6-2. The order of data to be stored in 6-3 and the corresponding storage units 7-1 of the sequence number storage unit 7
．． Sequence number 204.205 stored in 7-2.7-3
From this figure, it can be seen that input data is assigned a sequence number according to the order in which it was input, regardless of which data input device it came from. Therefore, in this state, data ''2'' in the data input table fill is
In this case, data 14 and data ``212''CR can be viewed by the data input device 3 as the data at the head of the pointer.

FIG. 3(c) shows the state after the input data reading unit 10 has read the data with sequence number 1. At this time, the data in the data input device 2 is the data with sequence number 2 ``II 8''. It can be seen that the data becomes ## and the data ``5'' with the order number 4, and the others remain as they are.

In addition, when data is not ordered as in the conventional example, data can only be read in a predetermined order from multiple data input devices.
So, for example, this reading order is a data input device! l→
If the order is 2 → 3 → 1, etc., then data can only be read in this order, and the order in which the data is read is as follows.

Although the data will be arranged in an arrangement that has nothing to do with the order in which it was actually input, there is no need to worry about this in practice.

Then, a process is performed to store the number of the data input device in the -time storage section 12.

Here, in step 403, the presence or absence of input data is checked,
If there is data, the process goes to step 404, and if there is no data, the process goes to step 402.

In step 404, input data is read based on the storage contents of the temporary storage section 12, and each pointer is updated.

These processes are repeated as long as the data exists according to the judgment process in step 405, and the main routine is ended.

Next, FIG. 5 shows an input control processing procedure DEN for inputting data before being processed in the main routine.
This is the flowchart showing T! The processing procedure DENT is started and executed when data is input from any of the data input devices i11 to i3, regardless of the operation of the main routine shown in FIG.

D is an input device order determination processing procedure ISO in which data is read from the input data status storage unit based on which input device data was input first.

Below, each step in FIG. 8 will be explained. First, in step 801, input data/status is input to the corresponding human-powered device based on the input device number indicated in the input device number-time storage section and the pointer in the storage section storage section of the corresponding input device. Step 802 of reading data from the data/status storage section involves changing the setting of the pointer used to read data in step 801 to a pointer at the top position where the next data is located, and one-to-one correspondence with the corresponding data. It stores the starting position of the sequence number storage section in which the ordering of the sequence is stored. Change the setting of the data start position pointer in the sequence number storage unit to the position of the next sequence number. After step 802 is completed, the data reading process is completed.

Now, returning to the flowchart of FIG. 5, regarding the input control processing procedure DENT for processing data input from the input device processed in the main routine explained above,
I will explain in more detail.

As described above, the input control processing procedure DENT shown in this embodiment is called every time data is input from the input device, regardless of whether the main routine is in operation or not. In other words, when data is input from each input device, this input control process is activated at any time, checks the presence or absence of data in the input device, obtains data from the device where input data exists, and returns the data in the order in which the input data is increased by 1. The order of input data is taken in from the number generation section, and the data from the input device is stored in the input data/status storage section stored for each input device in the data/status storage section indicated by the data end position pointer. One-on-one with Koto and Data
The sequence number corresponding to is stored in the sequence number storage section indicated by the sequence number storage section data end position pointer.

If not, the process proceeds to step 503, and it is determined in step 22 whether or not the data has been input from the human input device 2. If so, in step 504, it is determined that data has been input from the input device [2]. The data is stored in the data input storage unit 13, and the process moves to step 507. If not, the process moves to step 505, where it is determined whether or not the data input device 3 is used. If so, the process moves to step 506, and here In step 506, it is determined whether or not the data has been input from the input device !3, and in step 506, it is stored in the data input storage unit 13 that data has been input from the human input device ffl3, and the process proceeds to step 507. If not, the input control process ends.Step 507 updates the count of the sequence number generation unit indicating the sequence number of the input data by 1, reads the updated number, and stores the count in the storage unit corresponding to the input device number. The data end pointer in the sequence number storage section of the corresponding input device in the usage pointer storage section is updated.Step 508 receives and receives data ' from the input device after data input, and uses this data in the next step 509. Based on the position indicated by the input data/status storage section data end position port C lid, the input data/status storage section corresponding to the input device in the storage section usage pointer storage section is stored in the input data/status storage section, and the above pointer position is updated. Then the process ends.
