Blueprint device with a filter arrangement

摘要

In a blueprint device in which the prints, which have been developed in the developing station and heated in the process, leave the housing of the device through an exit, the exit is constructed as an exit shaft which has a top-side filter mounted on the housing of the device, so that while passing through the exit shaft the prints give off into the filter the residual gases rising because of the heat, without the necessity of an extraction device for this purpose.
