Abstract
Disclosed is an analytical apparatus wherein a container is automatically transferred and the container is automatically closed with a cap member, said analytical apparatus being provided with a suitable mechanism that reliably closes the container. The analytical apparatus is provided with an optical sensor composed of at least one pair of a light source (4) and a light detector (5), which face each other with the container disposing position therebetween, and which are disposed such that the container disposing position is irradiated with light, and the analytical apparatus detects whether the container (1) is disposed or not or the absence/presence of the cap of the container, corresponding to a transmitted light quantity detected by means of the optical sensor. Thus, cap closing is prevented from being performed if there is no container, and the container is prevented from being transferred without the cap.
