Abstract: A sensor chip includes a substrate, a relief structure composed of protruding sections formed so as to be arranged on a surface of the substrate to have a lattice shape and a recessed section between the protruding sections, and fine metal particles arranged along upper ridge lines of the respective protruding sections of the relief structure, the protruding sections being adjacent to each other, having a minute gap with which the surface plasmon resonance occurs. By irradiating the gap between the fine metal particles with a laser beam, the localized surface plasmon resonance occurs more efficiently. As a result, the sensor chip capable of taking out the surface enhanced Raman scattering to thereby detect the substance with high sensitivity can be realized.

Abstract: A printer includes first transporting belts disposed in parallel at predetermined intervals in the direction intersecting the direction of transportation of print media. The first transporting belts transport a print medium while adsorbing the print medium. Second transporting belts disposed in parallel at predetermined intervals in the direction intersecting the direction of transportation of print media further transport the print media. The second transporting belts are separated from the first transporting belts at the downstream part of the first transporting belts in the direction of transportation of print media. A print head prints on the print medium. The position of separation at which the print medium is separated from the first transporting belts is different in the direction of transportation of print media between one of the first transporting belts and another one of the first transporting belts.
