<p>A position detection mark (18) is provided to have any of a reflective surface, a refractive surface and a light shielding surface for blocking output light that is incident on a sensor (113) from a light source (12) when the output light arrives at a rotation position right before or behind measurement spots (17a, 17b, 17c) of an analyzing device (1). The analyzing device stores an output signal of the sensor (113) at a memory (28), wherein the sensor (113) reads out the measurement spots (17a, 17b, 17c), judges positions of the measurement spots (17a, 17b, 17c) from light receiving data stored at the memory (28) and extracts only a target analyzing signal, thereby reading out each measurement spot without adding components even if the number of spots increases.</p> |
