<p>PURPOSE:To draw the decision information effectively without reholding an input stylus nor shifting the operator's eyes by providing the buttons, etc. in numbers needed for switching and changing the functions according to the operations of those buttons. CONSTITUTION:An input/output device 11 contains a display screen and a coordinate input device which are unified to a controller 13 of the coordinate input device. Three buttons 81-83 are provided at the forward left corner of the device 11 to designate the change among the drawing, erasion and pointing modes. While pointers 81'-83' are set at the left position slightly higher than the center part of the device 11. In another example, the buttons 81-83 are set on the upper surface side of a switch box separated from the device 11. Then the switch box is connected to the device 11 via a cable 85. Thus the functions are switched without reholding an input stylus nor shifting the operator's eyes by means of operations of buttons 81-83. As a result, the decision information is processed effectively.</p> |
