A light receiver has a shield wall disposed facing a part of a near-side light-receiving face of a light receiving element from an end opposite from a far-side light-receiving face. The shield wall blocks a portion of reflection light from a detection object located at a distance at which the detection object reflects reflection light that causes an amount of light received by the light receiving element to be larger than or equal to a predetermined value.

A passage is defined which provides communication among an input port, a chamber, and an output-ports-connecting fluid path. A path, in the passage, from the input port to the chamber is defined as a primary-side communication path. A plug is pressure-inserted into the primary-side communication path in a direction from the input port side toward the chamber, which blocks the primary-side communication path.


To provide an in-liquid fluorescence detection device capable of accurately detecting fluorescence in a liquid. An in-liquid fluorescence detection device includes a light source emitting an excitation light having a wavelength in which Raman scattered light is generated in a liquid in a wavelength band between first and second fluorescence wavelength bands toward the liquid, which can contain a first substance that emits light having higher intensities in the first fluorescence wavelength band as compared with in the second fluorescence wavelength band and a second substance that emits light having higher intensities in the second fluorescence wavelength band as compared with in the first fluorescence wavelength band; and a fluorescence detection unit detecting light in the first and second fluorescence wavelength bands.


A temperature management apparatus is provided with: a temperature management furnace having a space in which an article is disposed and temperature is managed; bar-like members containing a magnetic material; facing members, each of which faces a part of the side surface of each of the bar-like members and contains a magnetic material; drive apparatuses, which rotate the bar-like members about their center axes and change the relative positions of the bar-like members and the facing members; and a contact member, which moves in the temperature management furnace in association with changes of the relative positions of the bar-like members and the facing members, and which moves the article by being in contact with the article. The drive apparatuses are disposed outside of the space in which temperature is managed.
