Inkjet printer having an active ray source

An inkjet printer comprising:

• a head for emitting an active ray cure ink onto a recording medium;
• an active ray source for emitting an active ray to cure the active ray cure ink, wherein the active ray source is arranged at a rear of the head in a direction of a relative movement of the head with respect to the recording medium during emission of the active ray cure ink, and wherein the active ray source is arranged in a same side where the head is provided with respect to the recording medium;
• and
• a shield member for preventing the active ray emitted by the active ray source from directly or indirectly entering into a trajectory formed by an ink particle emitted from the head and reaching the recording medium, said shield member being arranged between the active ray source and the head, and said shield member being provided with:
• a first extension member extending in a first extending direction toward the recording medium and closer to a surface of the recording medium than a surface of the head from which the ink particles are emitted;
• and
• a second extension member extending from the first extension member toward the trajectory, in a second extending direction crossing the first extending direction;
• wherein a surface of the second extension member opposite to the recording medium is formed in a convexo-concavo form.
