Switch on → Program channel switch 65 switch "1" is light pen
Operate with 30 to turn on → Operate all seat designation switch 64 with light pen 30 → Operate evaluation switch 75 with light pen 30 → Operate booth tape recorder lock switch 68b with light pen 30 By turning on the switch, the operation switch can be switched by checking this procedure even when the procedure for switching the required operation switch is not known.

Further, as another example, although not shown here, when “help” is operated with the light pen 30, an “explanation help screen” 77a is displayed as a window in a part of the display pattern 77. In this case, since the display pattern 77 and the “explanation help screen” 77a are displayed separately in one screen, the “explanation help screen” 77a is displayed.
While operating the light pen 30 according to the switching operation procedure while operating the necessary switches on the display pattern 77 while watching the contents of the above, when the operation procedure is completed, operate the "Return" switch of the "Explanation help screen" 77a with the light pen 30. Then, by returning to the original display pattern 77, even when the required operation switch switching operation procedure becomes unclear, the operation switch can be switched by checking this procedure.

In the two examples of the help mode described above, after confirming the switch operation procedure on the "Explanation help screen" 77a, the corresponding switch must be operated according to the procedure on the display pattern 77. On the help screen 77b, by operating any of the displayed screen switches 81-84 with the light pen 30, each screen switch 81-84
It becomes possible to automatically switch a plurality of relevant switches related to the above according to the procedure.

That is, when the help switch 78 is operated with the light pen 30, the “description help screen” 77b is displayed. Screen switches 81, 82, 83, 84 are displayed on the "description help screen" 77b. The screen switch 81 is operated in order to “make all the slaves hear the sound of the teaching material 1”, and the display on the operation switch display pattern 8b required here (“program set”, “1”) , "ALL", "program set"). Similarly, the screen switch 82 is operated in order to "send the sound of the microphone to the teaching material 1 and send it", and the display pattern of the operation switch required here.
There is also a display on "8b"("1","McMix").

In order to perform the operation of "to make all the slaves hear the sound of the teaching material 1", the screen switch 81 is operated with the light pen 30.
According to the operation flow shown in FIG. 16, the corresponding switch is operated according to the procedure (the program set switch 69 is turned on (step) → the switch "1" of the program channel switch 65 is turned on (step) → the all seat designation switch 64 is turned on (step) ) → Program set switch 69 is turned off (step)).

Thus, when the above-described flow ends, the operator operates the "return" switch 80 in the "description help screen" 77b with the light pen 30 to return the screen to the original display pattern 77.

The switching data stored by pre-stepping the switching procedure related to each of the steps 1 to 3 described above is stored in the input device 7.
The ROM3 of the control device 9 previously described by the input operation of
7, It is stored in RAM38 in the following order.

Address 1 ... Program set switch 69 on.

Address 2 ... Turn on the program channel switch 65 switch "1".

Address 3 ... All seat selection switch 64 is turned on.

Address 4: Program set switch 69 is turned off.

This switching data is automatically called in sequence and executed.

The change in the state of the display patterns 77, 77a, 77b is serially communicated to the base unit 6 and the analog switches 17a, 17b of the central control unit 6B and the voice control unit 6A are switched. For example, when the all-seat designating switch 64 is turned on, the program voice signal from the master unit 6 supplied to the slave units 10A to 10N is switched to PGM1.

Further, in order to be able to register the above-mentioned automatic switching operation procedure, it may be performed as follows.

First, select "Register automatic switching operation procedure" on the menu screen, and write the flow switching data as above with the light pen.
After operating various switches and inputting at 30, the "registration end" switch 79 displayed on the display pattern 77 as shown in FIG. 15 is turned on.

As a result, the input switching operation procedure data is recorded in the RAM 38 of the control device 9 and can be reproduced by the above-described method, so that the operator can perform the switching as desired. When a floppy disk drive device is attached to the control device 9 in parallel with the input device 7, it is possible to store this data in a floppy disk and read this data from there.

In this way, from the function description display, you can proceed while checking the function in multiple steps without error, so that even beginners can surely achieve the purpose and practice this operation, and explain the function. Since it can be executed on the spot, it can be used for abstract purposes (that is, it can be the purpose itself, not the role of the switch), and it is easy to use because it is possible to perform software-oriented operation rather than hardware operation.
Further, although the operation cannot be understood when there are many switches, the present invention has an effect that the number of switches can be practically reduced because the combination is executed.

In the above description, the display pattern of the display device 8a, 77,
It has been described that the input data is input to the 77a and 77b by operating the light pen 30, but it goes without saying that a method other than this, for example, a mechanical switch or a screen switch of a touch panel type can be similarly realized.

(Effects of the Invention) As described above, the language learning device according to the present invention is
A display device that displays an input image necessary for group learning and an input function explanation image, and an input operation corresponding to the input image of the display device, and an input that responds to the explanation of the input function by reading the input function explanation image An input device that performs an operation, and a control device that outputs a display signal that displays the content of the input operation of the input device and the processing result of the input operation to the display device as an input image each time the input operation is performed, For example, each time an input operation is performed using a light pen, a touch panel, a key switch, etc., the contents of the input operation and the processing result of the input operation are sequentially displayed on the image of the display device, so that the master side performing the input operation By checking the image on the display device every time an input operation is performed, the teacher can prevent mistakes in the input operation procedure and ensure that the correct input operation is performed. Even if the sequence of input operations becomes unclear, a large number of steps can be performed without error by reading the input function explanation image and performing the input operations sequentially according to the description of this input function. Can be surely executed, and as a result, there is an effect that teaching using the group learning device can be smoothly performed.
