Abstract: PURPOSE: To save the space of office by connecting a 1st input to a display controller, connecting a 2nd input to the video signal connector element of a connector, providing a switch means connect the output to a display device, and controlling the switch means through the display controller. CONSTITUTION: When connecting a control circuit board 1 to a control unit 21, an MPU 23 detects whether an MFI mode or a PC mode is selected, and a control signal for controlling a switch 7 is supplied to a display controller 5 on the control circuit board 1. As a result, a composited video signal in the APA graphic mode of the PC mode is supplied from the display controller 25 through a line 35 and a position 7B of the switch 7 to a display device 14. Then, a composited video signal in the MFI mode and the text mode of the PC mode is supplied from the display controller 5 through a position 7A of the switch 7 to the display device 14.

Abstract: The display controller incorporates means (microprocessor 22) to position the cursor on a screen (28) rapidly from its present location to operator selectable fields, whose positions are indicated by special codes in the refresh buffer (24). A special selectable field tab key (33) is provided in the keyboard to activate this function.
