EXAMPLE An example of the present invention will be described below. In FIG. 1, reference numeral 1 denotes a CRT display device having an integrated display function capable of displaying the first screen and the second screen as an integrated screen, and a split display function capable of displaying the first screen and the second screen as independent display screens. Is a split switch for selecting whether to use the integrated display function or the split display function of the CRT display device 3, 3 is a first screen controller for operating the first screen, and 6 is a first screen controller A first screen keyboard for inputting operation information to 3; a second screen controller for operating the second screen; 4 a second screen
The second screen keyboard 2a for inputting operation information to the screen controller 4 is provided with the first screen controller 3 and the second screen controller 4 or the first screen when the integrated display function is selected by the division switch 2. An operation selection switch 5 for selecting which of the keyboard 6 and the second screen keyboard 7 to use is exchanged and stored information between the first screen controller 3 and the second screen controller 4 and divided. This is a screen display memory that continuously displays the first screen and the second screen when the integrated display function is selected by the changeover switch 2, and this embodiment is the screen division changeover switch 2 in the MMI, two sets of screens. CRT with display (operation) controller and keyboard
It is a screen split display device that can display and operate two screens at the same time with one device, and switches between one screen size display as usual and split (two screen display in this case) for one CRT device. , One CRT device enables simultaneous display and operation of two screens.

That is, the configuration of this embodiment is such that one CRT device 1, a split changeover switch 2 for switching between normal display and split display, a first screen controller for normal display and for split display. 3, a keyboard 6, a second screen controller 4 for split display, a keyboard 7, and a screen display memory 5 that stores the display contents of the screen. This apparatus displays a screen (one screen) of the same size as the CRT as usual when the normal display is performed with the division changeover switch 2 turned off.
(At this time, the controller uses the controller for the first screen and the keyboard.) Then, by turning on the division switch, the CRT screen is divided into two, and the first screen and the second screen are displayed on one CRT device. At this time, the display screen size is the same as the normal size, a part of the screen is displayed, and the screen display can be freely moved by the scroll function. Although an example is shown in FIG. 2, a screen that cannot be displayed on one screen and that spans two screens can be monitored as a connected screen.

When the division switch 2 is turned on, the controller and keyboard corresponding to the respective screens become effective and the first and second individual screens are expanded and operated (control).
Can be carried out. At this time, since the screen display memory is shared, the same screen development (the registration screen is the same) can be performed in both the first and second screens. In addition, the CRT screen 1
There is no need to create separate software in the section like the interrupt screen that displays a small window screen (crown display).

As a result, one MMI can realize functions such as operability of the conventional two MMIs.

As another embodiment, multi-division display such as 4-division, 6-division, etc. can be mentioned. However, the storage space for the controller may increase. Also, without dividing the screen,
It is also possible to perform so-called overlapping display in which two screens are simultaneously displayed on the screen of the CRT device.

This embodiment solves the problems raised as follows.

(1) One screen displays a fixed screen, the other screen is expanded, and a necessary screen is displayed to display one screen (previous No. 1).
→ No. 2 → No. 1 → No. 3 → No. If it was expanded as No. 1, No. By fixing No. 1, Two
→ No. 3) is not required, and quick improvement is possible.

(2) Since two screens can be displayed and two screens can be operated at the same time, two operators (even one person) can simultaneously operate two screens.

(3) Since the functions of two conventional MMIs are reduced to one, the installation space of the device is halved, the operability is doubled, and space saving is realized.
