光量調整が必要であつた。[Prior Art] Recently, a microbial monitoring monitor has been proposed in which a waterproof box with a built-in television camera is immersed in wastewater, and the state of microorganisms in wastewater can be directly monitored using the television camera. However, conventional TV cameras have a structure in which the magnification of the lens system cannot be changed automatically, and when changing the magnification, the entire lens system must be replaced. When changing this magnification, the focal length of the lens system changes, so the slit width of the sample chamber must be changed each time.
It was necessary to adjust the light intensity.

て光量の自動調整も行うようになつている。 A television camera 2 placed inside the waterproof box 1 is connected to a television monitor (not shown). The lens 2a of this television camera 2 is a microscope lens, and an electric zoom lens is used, and the magnification can be remotely controlled by a control unit 7 connected to a zoom lens control cable 6. There is.
Additionally, it is desirable that the focus be automatic. A light source 8 is also arranged inside the waterproof box 1, and is connected to a control unit 7 via a cable 9.
, and automatically adjusts the amount of light in response to changes in the magnification of the television camera 2.

The microcontainer 4 forms a sample chamber 5 that communicates with wastewater. The shape of this sample chamber 5 is such that its thickness a is preferably within 3 mm, and its length b is 5 mm or less, so as not to be affected by the flow rate of waste water.
Form to mm or more.

A pressure pipe 10 is connected to supply sewage or the like under pressure or to suck sewage from here, and by supplying the sewage in a timely manner, the sewage to be treated can be replaced and the inside of the liquid contact part 3 and the sample chamber 5 can be cleaned. can be carried out effectively. When suctioning wastewater, it is recommended to introduce the wastewater into an aspirator, generate negative pressure, and suction it.

変更に対応して移動するように形成されている。 Further, a reflector plate 11 is attached to the side wall of the microcontainer 4, facing the liquid contact part 3, and reflects the light from the light source 9 to remove microorganisms in the wastewater to the television camera 1.
It is now possible to play back clearly. here,
The reflector plate 11 is formed of a motorized member so as to be able to adjust the slit width of the sample chamber 5, that is, the distance to the liquid-contacting part 3, and is capable of changing the magnification of the lens by means of a control unit 7 to which a reflector control cable 12 is connected. It is designed to move.

確な微生物相の把握が行える。 According to the above configuration, the sewage to be monitored is not affected by the flow rate of the sewage in the sample chamber 5, so that enlarged microorganisms and the like are directly and continuously visualized on the monitor television. Furthermore, the magnification of the TV camera 2 is changed according to the microflora,
Correspondingly, the slit width and light intensity of the sample chamber 5 can be automatically adjusted, so that clear images and accurate microbial flora can be obtained at all times.

る。 Note that when the magnification is high, the slit width is very narrow, so it is preferable to automatically move the reflector and widen the slit width when changing the cleaning sample. Furthermore, if the slit width is narrow, the sample solution will hardly be replaced as it is, so if dye is supplied here and dyeing is performed, it is possible to fix filamentous bacteria, mold, etc.
