Title:
ANALYTICAL APPARATUS AND DETECTION METHOD EMPLOYED IN ANALYTICAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/080894
Kind Code:
A1
Abstract:
Disclosed is an analytical apparatus wherein a container is automatically transferred and the container is automatically closed with a cover 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 receiver (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 cover of the container, corresponding to a transmitted light quantity detected by means of the optical sensor. Thus, cover closing is prevented from being performed if there is no container, and the container is prevented from being transferred without the cover.
