1. A DNA-array-equipped cartridge comprising:
- a housing rotatable about a center axis;
a plurality of fluid containing spaces formed inside the housing and including a plurality of reagent containing spaces and a DNA array space, the reagent containing spaces holding fluids for preparation of target DNA, the DNA array space formed in a circumferential shape coaxial with the center axis and having a plurality of DNA probes spotted along the circumferential shape; and
a plurality of openings communicating with the corresponding fluid containing spaces, formed on an upper side of the housing, and arranged side-by-side along a circumference coaxial with the center axis,wherein rotating the housing allows the plurality of openings to sequentially face a position setting a fluid port of a reaction tank independent of the housing, and allows the plurality of DNA probes to sequentially face a position setting a light detector independent of the housing.

Abstract
Rotating a cartridge body 54 allows distribution ports and a combined distribution port provided in the cartridge body 54 and a channel inlet 53c provided in an upper surface of a ring array 53 to sequentially face a fluid port 30a of a reaction tank 30 independent of the cartridge body 54. Additionally, rotating the cartridge body 54 allows a plurality of DNA probes 53a to sequentially face a collimating lens 62a serving as a light detector independent of the cartridge body 54.
