The request is sent to the program control unit 16. Then, as shown in the flowchart of FIG. 4, the program control unit 16 terminates the processing of the program that is currently activated (running), and obtains the page information (number of pages) stored in the page information storage unit 14.

Thereafter, a display page set command for switching and displaying the page corresponding to the page information on the display unit 6 of the multi-item input device 1 is issued to the command transmitting unit 13, and the command transmitting unit 13 outputs the page information. The corresponding page setting command is transmitted to the multi-item input device 1, and the program control unit 16 performs an updating process to delete the page information from the page information storage unit 14 and returns to the first process in FIG.

When the command receiving section 9 of the multi-item input device 1 receives the page setting command, it sends it to the display control section 7, and the display control section 7 sends the page data corresponding to the command from the page data storage section 8. It is read and displayed on the display unit 6.

In this way, when the execution of a certain program is interrupted and another program is activated, the display page of the interrupted program is stored and the other program is terminated and the original program of the interrupted program is terminated. When the program returns to the execution, the page corresponding to the interrupted program is automatically displayed on the display unit 6 of the multi-item input device 1, so that the operator does not need to perform the page switching operation when switching the program. Input efficiency also increases.

Next, a second embodiment of the present invention will be described. FIG. 5 is a block diagram showing the configuration of the data processing system in this embodiment, and the portions common to FIG. 1 are assigned the same reference numerals.

C. CMD, LMN. CMD, XYZ. When a plurality of tasks (task Nos. 1, 2, 3, ...) Which are CMD, ... Are selectively executed, each task number and program I
D, the number of display pages in each program, and a flag indicating whether or not the program is set to be executed in the foreground task are stored.

Here, the task number. The number of pages displayed when the program 1 is executed is 1, task N
o. When the program of No. 2 is executed, the number of pages displayed is 20, and the task number. The number of display pages when executing the program of No. 3 is 20, and the task number. Flags (*) 20 indicating that the second program is currently set to the foreground are stored.

Next, the processing in the data processing system of this embodiment will be described with reference to the flow charts of FIGS. 6 to 9. The parts common to the first embodiment, that is, the processing shown in the flow charts of FIGS. The description of the common parts will be omitted as much as possible.

First, it is assumed that a plurality of tasks are selectively executed in this data processing device, one task is executed in the foreground, and the other tasks are executed in the background. In this state, if there is a touch input on the input unit 4 of the multi-item input device 1, the input control unit 11 of the data processing device 2 checks the content of data corresponding to the touch input, as shown in the flowchart of FIG. ..

If the content of the data is a task switching request, the request is sent to the task control unit 18, and the process proceeds to the process shown in the flowchart of FIG. When the task control unit 18 issues a command requesting the page information of the page currently displayed on the display unit 6 of the multi-item input device 1 and receives the page information returned by the command from the data receiving unit 15. , It is stored in the task information storage unit 17,
Update the data.

After that, the page information corresponding to the designated task, that is, the task for which the switching is requested is read from the page information stored in the task information storage unit 17, and the page corresponding to the page information is displayed. A display page set command is sent from the command transmission unit 13 to the multi-item input device 1, and execution of the designated task is switched.

At the same time, the display on the display device 3 is switched to the display corresponding to the program of the task, the flag 20 set in the foreground in the task information storage unit 17 is updated to the task, and the multi-item input device 1 Then, the page corresponding to the received display page set command is displayed on the display unit 6.

Further, the input control unit 11 of the data processing device 2
Checks the content of the input data, and if the content is a new task start request, sends the request to the task control unit 18, and proceeds to the processing shown in the flowchart of FIG. Task control unit 18
Adds a task information column for storing page information and the like corresponding to the new task to the storage area of the task information storage unit 17 and executes the program of the new task for which the start request is made in the foreground.

After that, if the data content received by the input control unit 11 is a task end request, the request is sent to the task control unit 18, and the processing shown in the flowchart of FIG. 9 proceeds. The task control unit 18 terminates the execution of the program of the task for which the termination request is issued, and performs an update process of deleting the page information corresponding to the program of the terminated task from the task information storage unit 17.

Then, instead of the terminated task, one of the programs executed in the background task is transferred to the foreground task and executed. For example,
The task that was running in the foreground before starting the terminated task is run again in the foreground,
A page corresponding to the task is displayed on the display unit 6 of the multi-item input device 1.

In this way, when the data processing device 2 selectively executes a plurality of tasks, a page corresponding to the switched task is automatically displayed on the display unit 6 of the multi-item input device 1 every time the respective tasks are switched. Since it is displayed, the operator does not need to perform page switching operation when switching tasks, and the efficiency of item input is improved.

Next, a third embodiment of the present invention will be described. The data processing system of this embodiment has a function of selectively executing a plurality of tasks in the data processing device 2 like the data processing system shown in the second embodiment, and the tasks of the data processing device 2 are further implemented. Control unit 18
However, it also has a function of updating the page information stored in the task information storage unit 17 in response to a page switching command issued from a program being executed by a background task.

FIG. 10 is a flow chart showing the processing when the page switching command is issued. When a page switch command is issued from any of the programs being executed, the task number of the program that issued the page switch command is obtained as shown in FIG.

When the task number is obtained, the task number stored in the task information storage unit 17 shown in FIG.
The presence or absence of the flag 20 shown in (1) is checked to determine whether the task is being executed in the foreground or the background. If it is being executed in the foreground, the process is terminated as it is, but if it is being executed in the background, the page information in the task information storage unit 17 is updated by the page switching command issued by the program.

For example, the task No. shown in FIG. When a command for switching to page 10 is issued from the program (ABC.CMD) being executed in 1, the program is being executed in the background, so the data "1" for that page is updated to "10".

In this way, when the task is switched, the page displayed corresponding to the task can be changed by the page switching command issued by the program running in the background. If the user wants to change the page displayed in, it is not necessary for the operator to perform page switching operation, and the efficiency of item input can be improved.

[0058]

As described above, according to the data processing system of the present invention, after the execution of a certain program is interrupted and another program is executed, the program is terminated and the original program interrupted is executed. When returning to the execution, the page displayed immediately before the interruption of the program can be automatically displayed on the display unit of the multi-item input device.

Further, every time the task is switched, the page corresponding to the switched task can be automatically displayed, or the page changed by the background task at that time can be displayed. Therefore, the complicated operation of page switching by the operator can be eliminated.
