<p>PURPOSE:To realize the highly accurate position control for an operating switch panel by controlling the position of a display screen so as to secure coincidence between a mark put on a gauge to show the prescribed one of those touch switch addresses and the corresponding address of the display screen. CONSTITUTION:A control tool 40 is set into a cover 35 so that the guide part 42 of the tool 40 touches the inside of the guide part 35a of the cover 35. Then the tool 40 is put on the screen of a CRT 20. Thus the coincidence is secured between the address of a touch switch device 30 and the address of a picture displayed on the CRT 20. Under such conditions, the center of a cross-shaped mark M of the tool 40 is coincident with the center address (xc, yc) of the device 30. AT the same time, a test device is connected to a main controller to display a cross-shaped test pattern (m) on the CRT 20. Then a volume is turned to secure coincidence between the mark M and the pattern (m). Thus the shift of the mark (m) is controlled on the screen. In such a way, the position of an operating switch panel is controlled with high accuracy.</p> |
