出扉15上の塵埃が外部に滑り落ちる。The dust collection chamber surrounded by the dust discharge door 15 of the intake / exhaust device 6 and the dust removal filter 12 becomes a negative pressure through the dust removal filter 12 by the fan motor 14 rotating the fan 13 in the forward direction. This allows the dust discharge door 15
Is sucked in a direction to close the space between the dust collecting chamber and the outside air, and a negative pressure applied to the hollow arm 4a is applied to the intake nozzle 5,
The air in the intake nozzle 5 is sucked into the dust collection chamber, the dust that is mixed with the air is removed by the dust filter 12 and stays in the dust collection chamber, and the air thus dusted is sucked by the fan 13. -It is discharged to the outside of the space 2. When dust is placed on the dust discharge door 15 and becomes heavier, the dust discharge door 15 rotates clockwise in FIG. 3, whereby the loaded dust slides down and the dust discharge door 15 becomes lighter. It is sucked by negative pressure and rotates counterclockwise to close the dust collection chamber. It should be noted that when the fan 13 is stopped, its own weight is applied, and when the fan 13 is rotated in the reverse direction, a positive pressure due to this is also applied, and the dust discharge door 15 rotates clockwise even if the amount of dust on the dust discharge door 15 is small The dust on the dust discharge door 15 slides down to the outside.

る。The electric motor 9 with a reduction gear has a built-in limit switch for detecting the upper and lower limit angles for restricting the rotation angle of the output shaft. These limit switches are installed in the electric motor 9 and the fan motor 14. It is connected to an energization control circuit 10 which is composed of a circuit (motor driver) for conducting forward and reverse energization and a controller. In the energization control circuit 10, when the limit switch for detecting the upper limit angle is opened, the forward rotation energization circuit is opened, and the reverse rotation energization circuit energizes the electric motor 9 for reverse rotation. When the limit switch for detecting the lower limit angle is opened, the reverse rotation energization circuit is opened, and the forward rotation energization circuit energizes the electric motor 9 for forward rotation. This causes the intake nozzle 5 to reciprocate. During this reciprocating agitation, the energization control circuit 10 energizes the fan motor 14 for forward rotation.
Dust discharge door 15 of intake / exhaust device 6 and dust removal filter 1
Negative pressure is applied to the dust collection chamber surrounded by 2, the air is sucked by the intake nozzle 5, and the dust discharge door 15 closes the space between the dust collection chamber and the outside while the amount of dust loaded on it is small. ing.

る。Rain, snow, sand dust or dust adhering to the front window glass 3 of the camera case 2 is first pushed by the brush 8 to the outside of the intake nozzle 5, but a part of that which has entered the nozzle 5 is hollow. What has been sucked into the window 4a and adhered to the window glass 3 is wiped with the wiper 4, and when it falls off the glass 3, it is sucked into the hollow arm 4a. Therefore, when the window glass 3 is little dirty or scratched and the industrial TV camera used in bad weather or dust environment is housed in the case 2 of this embodiment, a captured image with high image quality can be obtained.
