Title: CLEANING DEVICE
Abstract:
The purpose of the present invention is to provide a cleaning device that makes it possible to efficiently remove both relatively large foreign matter and fine foreign matter from the surface of an object. The present invention is a cleaning device that conveys a plate-shaped or film-like object while removing foreign matter from the surface thereof, said cleaning device being characterized by the provision of: a brush roller rotationally driven in the reverse direction with respect to the conveyance direction by a rotating shaft that is substantially perpendicular to the conveyance direction and substantially parallel to a conveyance surface; a cleaning roller rotationally driven in the forward direction with respect to the conveyance direction by a rotating shaft that is substantially perpendicular to the conveyance direction and substantially parallel to the conveyance surface; a first facing roller arranged so as to face and be substantially parallel to the brush roller with the object therebetween; and a second facing roller arranged so as to face and be substantially parallel to the cleaning roller with the object therebetween. The surface hardness of the first facing roller is preferably higher than the surface hardness of the second facing roller. The first facing roller is preferably a metal roller.
