PROBLEM TO BE SOLVED: To provide an optical film sticking position measuring device capable of easily and highly accurately measuring an optical film sticking position by capturing image data of an optical display device.SOLUTION: The optical film sticking position measuring device measures an optical film sticking position with respect to an optical display device including an optical film stuck on an optical element, and comprises: a frame; an infrared light source provided on one end of the frame and emitting infrared; imaging means provided on the other end of the frame so as to receive the infrared; and a ring light source provided between the infrared light source and the imaging means. The infrared light source and the ring light source have substantially coaxial optical axes to each other, have emission directions of light facing each other, and include therebetween a space formed through which the optical display device passes. High accuracy measurement can be realized with a simple configuration by the optical film sticking position measuring device in combination with the infrared light source and the ring light source.SELECTED DRAWING: Figure 3 |
