Printing apparatus

A printing apparatus:

• comprising:
• a support member configured to support, with a curved surface thereof, a recording medium conveyed in a predetermined conveyance direction;
• an ejection head configured to eject a liquid from a nozzle of a nozzle surface arranged at a position facing the support member, to print an image on the recording medium supported by the curved surface;
• an irradiation section including:
• a housing;
• and
• a light emitting section configured to emit light for curing the liquid, the light emitting section being accommodated inside the housing,
• the irradiation section configured to irradiate the recording medium supported by the curved surface with the light emitted from the light emitting section through an irradiation port defined by the housing;
• a first light-shielding plate arranged between the ejection head and the irradiation section in the conveyance direction;
• and
• a second light-shielding plate arranged between the first light-shielding plate and the ejection head in the conveyance direction, wherein
• the housing is arranged in a position far from the curved surface with respect to a virtual tangent plane that passes through a portion, farthest from the irradiation port, of the nozzle surface and is in contact with a lower end of the first light-shielding plate, and
• the second light-shielding plate is arranged in a position that allows the second light-shielding plate to block at least part of light, entering a side surface orthogonal to the nozzle surface of the ejection head, of the light that is emitted from the irradiation section and regularly reflected or scattered by the support member or the recording medium supported by the support member, and is arranged in a position so that a distance between a lower end of the second light-shielding plate and the curved surface is equal to or larger than a height of the nozzle surface from the curved surface.
