Abstract: An inspection module is disclosed for inspecting a droplet from an ink jet head. The inspection module includes a sensor located under the ink jet head and measuring a distance between the droplet and the sensor in real time; a variable lens changing an operating distance based on the measured distance of the sensor; and a camera for capturing an image of the droplet. The inspection module further includes a droplet inspecting part inspecting the droplet image captured by the camera.
