According to the study of the present inventors, the notch hole (the mounting hole of the unit) of the side plate of the apparatus. , Sliding holes in internal parts, etc.)
Inclusive leakage air the ozone from the apparatus side plate and the device-side
There is a phenomenon in which the device goes out of the device from the space between the device and the device cover provided outside the plate without passing through the ozone removing means. To make matters worse, the ozone-containing leaked air is sucked into a suction fan for sucking and taking in outside air, which is installed for the purpose of preventing the temperature of the apparatus and the optical system from rising and the temperature inside the machine to be increased. Together with the outside air suction flow, a phenomenon of being drawn into the machine again occurs.
