Exposure machine

The utility model discloses an exposure machine. A machine case is provided with a controller, a movable light emitting machine is provided with light emitting sources and a moving device, a first sensitising substrate lifting machine is positioned between two film fixing machines, two sensitising substrate moving machines are respectively used for moving the sensitising substrate between sensitising substrate receiving machines and the first sensitising substrate lifting machine and used for moving the sensitising substrate between the first sensitising substrate lifting machine and sensitising substrate withdrawing machines, and the light emitting sources are arranged on the moving device and reflect light rays through reflecting mirrors to the sensitising substrate on the first sensitising substrate lifting machine. The exposure machine disclosed by the utility model can automatically exposure the front and the back of the sensitising substrate and can continuously place the sensitising substrate for exposure.
