Abstract

A paper guiding device in a copying apparatus includes, in opposition, a lower guide plate having a main flat portion and an upper guide plate having a main flat portion. A plurality of rising pieces, having top edges and being laterally spaced apart upon the upper side of the main flat portion of the lower guide plate, rise above the lower guide plate and extend in the direction of movement of the copying paper. A plurality of hanging pieces, having lower edges and are laterally spaced apart on the lower side of the main flat portion of the lower guide plate, hang from the upper guide plate and extend in the direction of movement of the copying paper. The top edges and the lower edges define a path of movement of the copying paper while having minimal contact with the paper. A plurality of openings through the upper guide plate and an opening through each of the hanging pieces dissipate heat from the copying paper to substantially prevent the accumulation of moisture on the copying paper and in the improved paper guiding device.
