置。[Scope of Claim for Utility Model Registration] (1) A device for removing ozone generated by an electrostatic recording device, which is a device for removing ozone generated by an electrostatic recording device, and is a device for removing ozone generated by an electrostatic recording device, which is a backflow device that rotates around a hinge part at the outlet of a fan so that it can be opened and closed. a shutter for preventing backflow; and a shutter for preventing backflow from the hinge portion in order to maintain a substantial weight balance with the shutter for preventing backflow so that the shutter for backflow prevention opens with a weak airflow from a fan and closes when the fan stops. A balancer filler protruding from the opposite side; and an optical sensor disposed at a position where the balancer filler blocks an optical path when the backflow prevention shutter is open and detects opening/closing of the backflow prevention shutter. An ozone removal fan device characterized by: (2) Judging from the opening/closing detection signal of the backflow prevention shutter by the optical sensor and the fan drive signal,
The ozone removal fan device according to claim 1, further comprising means for notifying an abnormality of the fan when there is no detection signal indicating that the backflow prevention shutter is "open" in a state where the fan must rotate. .
