<p>PURPOSE:To input a coordinate position and processing work from an input means and to execute a processing work to the coordinate position part of a drawing picture by a processing means by inserting an instruction pin, which corresponds to the processing work, into the input means provided on a large picture screen, on which the drawing picture is displayed, in a large screen system device. CONSTITUTION:An operator selects a drawing by a request panel 2 on a console 1 and drawing data are taken out of a disk device 6 by a CPU 5 in correspondence to the selected drawing and displayed through a video projector 8 to a large picture screen 7. The operator sticks an instruction pin 10, for which a resistance value is changed in correspondence to work contents to be processed, in the coordinate position of a purpose spot on this screen 7. A coordinate input device 9 receives the pin 10 by a process I/O and the processing work contents are transmitted to the CPU 5 by the coordinate position and the resistance value of the pin 10. Then, the CPU 5 receiving processing operation executes processing and a processed result is outputted through the projector 8 to the screen 7.</p> |
