Abstract
A monitoring apparatus is provided which can ensure the prevention of a paper break even in a poor installation environment. A light source () illuminates light () on a lateral edge () of wet paper () and a camera () captures light () reflected therefrom. The camera () is a micro camera and completely covered by a camera box (). The camera box () has an observation window () which is made of a transparent member, at the lens side () of the camera (). The outer surface of the observation window () is coated and an air curtain () that flows from above to below prevents staining caused by mist. The air curtain () is formed in such a manner that air that is continuously supplied inside a cover () flows along the outer surface of the observation window () from an opening portion (). A color image obtained by the camera () is subjected to image processing in an image processing device () and the resulting image is projected on a monitor TV (), so that variations of the release point () can be monitored. This allows for forecasting of a machine abnormality leading to a paper break.
