上記構成の動作を図１および図２を参照して説明する。図２に示すカメラハウジング装置１は、その前面である前面板１１の上部に開口孔１２が設けられ、その前面板１１の裏側には、図１に示すような清浄部６が備えられる。
図１において、カメラハウジング装置１は、清浄部６と仕切板８を介してその後部にカメラ収納部７が構成され、これにはカメラ装置１０が前向きに収納される。
これにより、屋外での撮影では、塵埃・風雨または日照などによるカメラ装置１０の電気／機械的弊害を防護し、また、撮像レンズ面に付着する水滴または汚れにともなう光学的障害に対処しながら撮影できる。The operation of the above configuration will be described with reference to FIGS. The camera housing device 1 shown in FIG. 2 is provided with an opening hole 12 in the upper part of the front plate 11 which is the front surface thereof, and on the back side of the front plate 11 is provided with a cleaning unit 6 as shown in FIG.

As a result, in outdoor shooting, the camera device 10 is protected from electrical / mechanical adverse effects caused by dust, wind, rain, or sunshine, and is also shot while dealing with optical obstacles due to water droplets or dirt adhering to the imaging lens surface. it can.

また、この清浄部６には、回転軸５で回動する光学回転板３が設けられ、回転軸５はカメラ収納部７側に設けた電動機に基づき連動する。この場合、光学回転板３は、これに点線の矢印で示す方向に前記回動するものとする。
そして、光学回転板３の前面がその回動にともない払拭されるように払拭子４を設置する。また、前記電動機のオン／オフ動作または速度を調整してもよい。さらに、払拭子４は一個でも複数でもよく、一組等の払拭子４で光学回転板３の両面を払拭してもよい。Further, the cleaning unit 6 is provided with an optical rotating plate 3 that is rotated by a rotating shaft 5, and the rotating shaft 5 is interlocked based on an electric motor provided on the camera storage unit 7 side. In this case, the optical rotary plate 3 is rotated in the direction indicated by the dotted arrow.
And the wiping element 4 is installed so that the front surface of the optical rotating plate 3 is wiped with the rotation. Further, the on / off operation or speed of the electric motor may be adjusted. Further, the wiper 4 may be one or plural, and both surfaces of the optical rotating plate 3 may be wiped with a pair of wipers 4.

ここで、仕切板８の上部には光学ガラス等を用いた撮影窓２を設け、これに近接して光学回転板３を配設する。また、カメラ装置１０の撮影レンズに基ずく撮影光軸は、それぞれ撮影窓２と、光学回転板３の上部部分と、及び図２の開口孔１２とを通し、必要とする視野角で被写体を撮影する。
このようにして、屋外での撮影では、塵埃・風雨または日照などによるカメラ装置１０の電気／機械的弊害を防護し、水滴／水濡れまたは塵埃等が撮影窓２に直接付着するのを防ぐ。そして、光学回転板３は、前記回動にともない光学回転板３の前面または両面の水滴／水濡れまたは塵埃等による汚れを払拭子４で払拭することにより、撮影窓２および撮像レンズ９の光学的障害に対処しながら撮影できる。Here, the photographing window 2 using optical glass or the like is provided on the upper part of the partition plate 8, and the optical rotating plate 3 is disposed in the vicinity thereof. The photographing optical axis based on the photographing lens of the camera device 10 passes through the photographing window 2, the upper part of the optical rotating plate 3, and the opening hole 12 in FIG. Take a picture.
In this way, in outdoor shooting, the electrical / mechanical adverse effects of the camera apparatus 10 due to dust, wind and rain, or sunshine are protected, and water droplets / wetting or dust or the like is prevented from directly adhering to the shooting window 2. Then, the optical rotating plate 3 is wiped with a wiper 4 to remove water droplets / water wetting or dust or the like on the front surface or both surfaces of the optical rotating plate 3 with the rotation. You can shoot while dealing with physical obstacles.

次に、前述の第２の課題解決手段によれば、仕切板８に通風孔を設けカメラ収納部７を介し清浄部６に空気を圧入して前記開口孔より排出する。
すなわち、モーターファンその他により、カメラ収納部７に空気圧を加える手段をカメラ収納部７またはその外部に備え、仕切板８の撮影窓２の上部等に設けた通風孔を介し、前記空気圧によりカメラ収納部７から清浄部６に空気を流入させる。
これにより、図２の開口孔１２より空気が排出することにより霧状の水滴または塵埃等の侵入を防止し、また、前記排出によりカメラハウジング装置内の熱を放出できる。
さらに、カメラ収納部７から清浄部６への前記空気の流入は、撮影窓２に添ってエアカーテン効果となるように流入することが望ましい。これにより、特に霧状の水滴または塵埃等に対する防御効果がある。Next, according to the second problem solving means described above, a ventilation hole is provided in the partition plate 8, and air is press-fitted into the cleaning part 6 through the camera storage part 7 and discharged from the opening hole.
That is, a means for applying air pressure to the camera housing portion 7 by a motor fan or the like is provided in the camera housing portion 7 or outside thereof, and the camera is housed by the air pressure through a ventilation hole provided in the upper part of the photographing window 2 of the partition plate 8 or the like. Air is caused to flow from the section 7 into the cleaning section 6.
Accordingly, the air is discharged from the opening hole 12 in FIG. 2 to prevent intrusion of mist-like water droplets or dust, and the heat in the camera housing device can be released by the discharge.
Further, it is desirable that the air flow from the camera storage unit 7 to the cleaning unit 6 flows along the photographing window 2 so as to have an air curtain effect. Thereby, there exists a protective effect especially with respect to a mist-like water droplet or dust.

また、第３の課題解決手段によれば、光学回転板３の回転軸５よりも下の部分と払拭子４とはそれぞれ清浄部６に貯水された水等の洗浄液に浸漬されて前記回動にともない該払拭子で払拭洗浄され、光学回転板３の面の一部分はそれが洗浄液より脱出した位置で上記払拭子とは別の払拭子により洗浄液の水滴／水濡れが払拭された面である。  Further, according to the third problem solving means, the portion below the rotating shaft 5 of the optical rotating plate 3 and the wiping element 4 are immersed in a cleaning liquid such as water stored in the cleaning unit 6 and rotated. Accordingly, a part of the surface of the optical rotating plate 3 is a surface where water droplets / wetting of the cleaning liquid has been wiped off by a wiping element different from the wiping element at a position where it has escaped from the cleaning liquid. .

これは、清浄部６の下部は水等の洗浄液を貯水できるものとし、光学回転板３の回転軸５よりも下の部分と払拭子４とは前記洗浄液に浸漬される。この洗浄液は別途容器に入れて容器ごと装填するようにすれば、洗浄液の交換が容易となる。
これにより、光学回転板３は、前記回動にともない該払拭子で払拭洗浄され、光学回転板３が回動して前記洗浄液面より脱出した位置で、上記払拭子とは別の払拭子により洗浄液の水滴／水濡れを払拭するものである。また、前記払拭洗浄および別の払拭子による洗浄液の水滴／水濡れの払拭は、光学回転板３の両面についても行なうことが出来る。This is because the lower part of the cleaning unit 6 can store a cleaning liquid such as water, and the portion below the rotating shaft 5 of the optical rotating plate 3 and the wiper 4 are immersed in the cleaning liquid. If this cleaning liquid is put in a separate container and loaded together with the container, the cleaning liquid can be easily replaced.
As a result, the optical rotating plate 3 is wiped and washed with the wiping element along with the rotation, and at a position where the optical rotating plate 3 rotates and escapes from the cleaning liquid surface, a wiping element different from the wiping element is used. It wipes away water droplets / wetting of the cleaning liquid. The wiping cleaning and the wiping of water droplets / water wetting with another wiping element can also be performed on both surfaces of the optical rotating plate 3.

さらに、第４の課題解決手段は、撮影窓２または光学回転板３は光学フィルタの作用を有するものである。
すなわち、撮影窓２または光学回転板３は、単なる透明な光学ガラス等によるものではなく、光学フィルタを用いることができる。これにより、例えば紫外線／赤外線その他の光学フィルタとして兼用できる。Further, as a fourth problem solving means, the photographing window 2 or the optical rotating plate 3 has an action of an optical filter.
That is, the photographing window 2 or the optical rotating plate 3 is not simply made of transparent optical glass or the like, and an optical filter can be used. Thereby, it can be used as, for example, an ultraviolet / infrared or other optical filter.

このようにして、本発明は、ハウジングの撮影窓を直接払拭することなく水滴／水濡れまたは汚れの蓄積を防いで光学的障害に対処しながら撮影でき、しかも、円弧状に往復移動する払拭子が撮影されて撮像画面が見ずらかったり、観測データに影響することのないカメラハウジング装置を提供できる。  In this way, the present invention is a wiper that can shoot while coping with optical obstacles by preventing water droplets / wetting or accumulation of dirt without directly wiping the imaging window of the housing, and reciprocating in an arc shape. Therefore, it is possible to provide a camera housing device that does not make it difficult to view the imaging screen and affect observation data.
