a head configured to eject a light-curable ink onto a printing object;
a lamp movable relative to the printing object in a main scanning direction, the lamp being configured to emit light to irradiate the printing object on which the ink ejected from the head is deposited;
a condenser lens configured to focus the light emitted from the lamp;
a platen configured to support the printing object and to move in a sub scanning direction relative to the head, the sub scanning direction crossing the main scanning direction; and
a lamp cover having translucency and configured to transmit the light focused by the condenser lens, the lamp cover including one end portion and the other end portion in the sub scanning direction, each of the one end portion and the other end portion having an adjustment part configured to adjust the light transmitted through the lamp cover by blocking part of the light or diffusing the light.
