摘要： A first irradiation section has a light source and an emitting member. The light source generates radiation, and the emitting member is located between a first irradiation point and a virtual plane that extends through the edge of a nozzle surface closest to the first irradiation section tangentially to a curved surface. The radiation generated by the light source goes out through the emitting member. A control section controls a transportation speed in such a manner that ink dots formed at a dot formation point should move to the first irradiation point in a second time period that is equal to or shorter than a first time period. The first time period is the time period from the time immediately after the ink dots are formed to the time when the diameter of the ink dots reaches twice the nozzle pitch.
摘要翻译：第一照射部具有光源和发光部件。光源产生辐射，并且发射构件位于第一照射点和虚拟平面之间，该虚拟平面延伸通过最靠近第一照射部分的喷嘴表面的边缘切向于弯曲表面。由光源产生的辐射通过发射构件流出。控制部以这样的方式控制运送速度，使得形成在点形成点处的墨点应该在等于或短于第一时间段的第二时间段内移动到第一照射点。第一时间段是从形成墨水点之后的时刻到墨点的直径达到喷嘴间距的两倍的时间段。
