  • Printing apparatus for printing by discharging ink to an upper surface of a base material in the form of an elongated strip
    Patent number: 11479043
    Abstract: Since a head part is arranged in an inclined posture, the ink ejected from a nozzle surface of the head part may drip to a first lower surface peripheral edge portion along the nozzle surface, and then drops from a first long side of a lower surface of the head part toward a first side wall of a cover member being arranged below the head part. The first side wall having an upper end portion is located away from the first long side. Thus, the dropped ink is collected by the cover member without being attached to the upper end portion of the first side wall. Therefore, the ink can be prevented from being solidified at the first lower surface peripheral edge portion and the reattachment of the ink to the nozzle surface can be effectively prevented.
