FIG. 1 is a block diagram showing the configuration of the control system of this embodiment. In the figure, the configuration of the two split input sections 3 and 4 among the split input sections 3 to 6 is shown. The other split input units 5 and 6 have the same configuration. The divided input units 3 and 4 are
A divided display unit 10 obtained by dividing the screen display unit 2 and a divided touch sensor panel unit 11 obtained by dividing the touch sensor panel.
And divided display unit 10 and divided touch sensor panel unit
11 is divided in a controllable manner, the dividing positions are the same, and the divided areas are substantially the same. An address is assigned to each of the divided input units 3 and 4.

Further, each of the divided input sections 3 and 4 is connected to a keyboard controller 12 capable of controlling each independently, and the keyboard controller 12 controls each of the divided input sections 3 and 4. Also keyboard controller 12
Is connected to a bus line 14 of a CPU (central processing unit) 13.

By dividing in this way, the division input unit 3,
Reference numeral 4 serves as an independent input device, and when the input does not have to be displayed on the display unit 1 as a whole, unnecessary split input sections are made non-display, and the input operation section is highlighted. By blinking unnecessary division input sections when an error occurs, the user can be notified at a glance that an error has occurred.

Further, all image information that can be displayed by the division input sections 3 and 4, that is, image information having the same size as the display screen of the division input sections 3 and 4 is defined as one unit (one page),
In addition, each page is assigned an address, and a ROM 15 which is a memory for recording image information page by page is connected to the bus line 14, and the ROM 15 can select image information by page number.

Further, in a certain input state, the address of the input device, the divided input device, is a rewritable memory for recording how many pages in the ROM 15 to be displayed.
