する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ozone removal device for use in electrophotographic copying machines and the like, which removes ozone (03) generated during corona discharge by a corona discharger that uniformly charges a photoreceptor.

電器が使用されている。An electrophotographic copying device uniformly charges the surface of a photoreceptor and exposes the image to light, thereby attaching a colored pigment called toner to an electrostatic latent image corresponding to the image to make it visible, and converting the toner image as appropriate. After the toner image is transferred onto the paper being sent, the paper is passed through a fixing section to fix the toner image and form a copy image. After the photoreceptor is transferred, the surface charge is removed, residual toner is removed by a cleaning device, and the photoreceptor is prepared for the next image formation. As mentioned above, in order to form an image on the photoreceptor, the photoreceptor is uniformly charged or neutralized, and the toner image is electrostatically transferred to paper in the transfer process, and a corona discharger is generally used as this device. has been done.

ルド板の一部に吸引口等を設け、上記７アーンを駆動す
ることでオゾンを吸引し外部に強制的に排気している。The corona discharger has a structure in which a conductive thin wire for corona discharge to which a high voltage is applied is surrounded by a shield plate whose surface facing the photoreceptor is open and grounded. It is generally well known that when a high voltage is applied to a wire to cause corona discharge, a large amount of ozone (03) is generated because the discharge occurs in the air. This generated ozone has an adverse effect on the photoreceptor and significantly shortens the life of the photoreceptor. In order to prevent this, the air is discharged from the inside of the corona discharger, and a hefern or the like is installed outside the copying machine to exhaust the air. In order to discharge ozone from the corona discharger, a suction port or the like is provided in a part of the shield plate, and the ozone is sucked in and forcibly exhausted to the outside by driving the 7-arne.
上記オゾンは、大変臭いの強い気体であり息切れ１頭痛
等の生理的作用が認められる。そのため、機外に排気さ
れたオゾンは人体に対して全く無害であるとはいいきれ
ず、機外に排気するのにも問題がある。The ozone mentioned above is a gas with a very strong odor, and physiological effects such as shortness of breath and headache are observed. Therefore, it cannot be said that the ozone exhausted outside the aircraft is completely harmless to the human body, and there are also problems in exhausting it outside the aircraft.

るため、コスト及びスペースの問題を残す。Conventionally, it has been proposed to provide an ozone absorption filter before or after the 77-n to absorb and decompose the exhausted ozone. However, since the air volume is considerably reduced by providing an ozone absorption filter, it is necessary to increase the size of the 7-arne for exhaust in order to perform the same exhaust as before. Furthermore, if the exhaust air 7 arn is also used as the cooling fur 2, the air volume will be reduced, resulting in a loss of cooling effect and the possibility of an abnormal temperature rise in the copying machine. For this reason, the exhaust fur 2 needs to be provided separately, which leaves problems of cost and space.

ゾンを吸収し分解するためのオゾン吸収剤を塗布して構
成されたものである。In view of the above, a device that absorbs and decomposes ozone generated within a corona discharger has been proposed and put into practice. This corona discharger is constructed by coating the inside of a shield plate with an ozone absorbent for absorbing and decomposing ozone.
該コロ°す放電器によれば、発生するオゾンが分解され
るため、オゾンを排気する必要がなくなる。According to the colloidal discharge device, the generated ozone is decomposed, so there is no need to exhaust the ozone.
しかしながら、上記オゾン吸収剤は半永久的に使用でき
るものではなく、どうしてもオゾンを吸収し劣化する。However, the ozone absorbent mentioned above cannot be used semi-permanently and inevitably absorbs ozone and deteriorates.

率が良好と−はいいきれない・ ・・：：。If the ozone absorbent deteriorates, the expensive corona discharger cannot be used as a disposable device, and the extremely troublesome work of wiping off the deteriorated absorbent with a solvent and applying new absorbent must be performed. Moreover, it cannot be said that this corona discharger has better biozone absorption efficiency than that of the exhaust fur 2.

排気される。The copying machine configured as described above uses a large-capacity heat source in the exposure and fixing sections. Therefore, parts that are easily touched by the user (such as the glass surface of the document table l) and various parts are exposed to high temperatures. Therefore, in order to cool the above-mentioned parts, a cooling fan 1-9 is installed on one side of the copying machine body to exhaust air from parts such as the document table 1, heat port, and rear 8 to the outside of the machine. It is located in The cooling fur 29 is rotationally driven by a drive source such as a motor, thereby creating a flow of air in the direction of the arrow through the opening 10 or 11, etc., and exhausting the air to the outside of the copying machine. At this time, excess heat generated in the lamp for exposure, especially illumination, and the fixing unit is exhausted so as not to reach a certain temperature or higher. Further, as shown in FIG. 1, ozone generated from inside the shield plates of the corona dischargers 5, 6, and 7 for charging, transfer, and neutralization is exhausted to the outside of the copying machine body along with the air flow.

Moreover, if the ozone removal efficiency deteriorates, the effect can be maintained by replacing the phage 9 itself, which improves serviceability.

As shown in the figure, corona dischargers 5 and 6
In response to this, the ozone generated within the shield plate is forcibly exhausted by the exhaust phage 12. As explained in FIG. 1, the evacuation phage I2 is constructed by forming the 7-arne itself with a member for absorbing or decomposing ozone, or by coating the surface of the phage with an ozone absorbent.

時に効率よくオゾンを除去できる。As described above, according to the ozone removal device for a copying machine of the present invention,
The 71-unit itself, which forcibly exhausts the ozone generated inside the corona discharger to the outside of the machine, has an ozone removal effect, so the ozone inside the corona discharger can be removed without reducing the air volume during exhaust. At the same time, it is possible to efficiently remove ozone when exhausting air to the outside of the machine.
