Patent ID: 8020512

Claim:
A pattern formation device comprising: a conveyance table configured and arranged to reciprocally move in a movement path extending in a primary scanning direction to convey a substrate mounted thereon; a pair of guide rails extending in a secondary scanning direction that is orthogonal to the primary scanning direction above the movement path of the conveyance table; a carriage supported by the guide rails, and configured and arranged to reciprocally move in the secondary scanning direction along the guide rails; a plurality of droplet discharge heads coupled to the carriage, and configured and arranged to discharge droplets of a functional liquid to the substrate to draw a pattern on the substrate while the substrate mounted on the conveyance table moves in the primary scanning direction; an inspection camera configured and arranged to capture an image of the droplets discharged from the droplet discharge heads; a camera base configured and arranged to couple the inspection camera to one of the guide rails; a linear motor configured and arranged to reciprocally move the camera base in the secondary scanning direction; a motor housing case disposed along the guide rails to accommodate the linear motor, the motor housing case having a guide opening configured and arranged to guide the camera base in the secondary scanning direction; a moving cable electrically connected to the inspection camera; and a cable housing case disposed along the motor housing case to accommodate the moving cable, the cable housing case having a window section through which a distal end of the moving cable follows a reciprocal operation of the inspection camera in the secondary scanning direction, the cable housing case having an exhaust vent at both end parts of the cable housing case to discharge air around the carriage by suction through the window section of the cable housing case.
