1. A sample processing system comprising:
a plurality of sample vessel holders each including a disk-shaped base section having a central axis extending in a vertical direction, and a sample vessel holding section that is disposed coaxially with, and above, the base section and has an outside diameter less than that of the base section, each sample vessel holding section is configured to hold a sample vessel in an upright posture; a conveying path that conveys the plurality of sample vessel holders placed thereon in a transport direction along the conveying path; and a holder holding mechanism, disposed adjacent to the conveying path, including a holding plate disposed extending along an outer peripheral portion of a columnar space that has a central axis extending in the vertical direction, wherein the holding plate has an open portion through which a sample vessel holder on the conveying path passes into the columnar space, wherein a drive motor is configured to rotate the holding plate around the central axis of the columnar space thereby rotating the open portion, wherein at least a portion of the holding plate rotates in a gap between the sample vessel holder holding the sample vessel in the columnar space and an adjacent sample vessel holder on the conveying path, and wherein the holder holding mechanism blocks or permits the sample vessel holder from being conveyed on the conveying path downstream of the holder holding mechanism in the transport direction based on an orientation of the open portion of the holding plate, which is rotated by the drive motor. |
