Furthermore, the shape of the guide hole 28 (guide hole 38) can be appropriately changed according to the shape of the first measurement unit 2 (second measurement unit 3) and the size of the mounting table 26 (mounting table 36). For example, the shape of the guide hole 28 (guide hole 38) of the present embodiment is formed in a straight line shape, but may be formed in a curved shape.
  • movement restriction unit 27 (movement restriction unit 37) is provided only on the one side plate 26c (one side plate 36c) of the mounting table 26 (mounting table 36), but the rear plate of the mounting table 26 (mounting table 36). 26b (rear plate 36b) or the other side plate 26d (the other side plate 36d) may be provided.
  • the sample processing system according to the present invention is a desktop type sample processing system in which a sample processing apparatus is installed on a base, and can provide a sample processing system with a high degree of freedom of installation location. It can be suitably used in the field of a sample processing system for performing processing.

Abstract

L'invention concerne un système de traitement d'un échantillon qui présente une plus grande souplesse sur les sites d'installation. Un élément en saillie (2k) (élément en saillie (3k)) qui fait saillie vers le bas est fixé sur une face inférieure (2f) (face inférieure (3f)) d'une première unité de mesure (2) (une deuxième unité de mesure (3)) à monter sur une base de fixation (26) (base de fixation (36)). Une ouverture de guidage (28) (ouverture de guidage (38) est formée sur une plaque supérieure (26e) (plaque supérieure (36e)) de la base de fixation (26) (base de fixation (36)), de sorte que l'élément en saillie (2k) (élément en saillie (3k)) s'adapte à travers celle-ci de manière à pouvoir effectuer une rotation dans le sens horizontal alors que le mouvement de celui-ci dans le sens horizontal est limité.
