PURPOSE:To provide an optical unit inspection jig capable of easily and precisely evaluating an optical unit without requiring an expert. CONSTITUTION:The optical unit inspection jig is provided with an original 3 for checking an image and an original 4 for checking illuminance 4 arranged in the original setting position of the optical unit 2, a light source 5 for checking for irradiating the original 3 for checking the image, an image checking means 11 receiving light projected from the light source 5 for checking at a position where the image is formed by this light after transmitting the original 3 for checking the image and then, passing through the optical system 6 of the optical unit 2 and an illumination sensor 12 receiving the light projected from a light source 7 in the optical unit 2 at the position where the image is formed by this light after being reflected by the original 4 for checking the illuminance and passing through the optical system 6, and analog signals outputted from an image checking means 11 and the illumination sensor 12 are A/D-converted to execute the data processing of the signals by a CPU 17. |
