<p>PURPOSE:To select visual and direct man machine interface device function even when abnormality is generated in a touch screen device by moving a marker by using a keyboard and providing a means to convert the coordinate data of the marker to processing at the input time of the touch screen when a request input is executed. CONSTITUTION:A signal line to transmit the coordinate data at the time of a coordinate input from a keyboard input processing part 12 to a touch screen input processing part 13 and a signal line to transmit a marker moving request from the keyboard input processing part 12 to a CRT display processing part 15 are newly provided. Thus, even when the abnormality is generated in a touch screen device 23, the function of a visually confirmed spot can be directly inputted to a screen equally with a case that the touch screen device 23 is normal. Then, even when the abnormality is generated in the touch screen device 23, the touch screen device 23 can be operated without the sense of incompatibility samely as a time that the touch screen device is normal.</p> |
