Apparatus and related method for correcting slide warpage in a slide projector |
摘要 |
Heat generated by the projection lamp in a projecting apparatus is used to individually pop slides having improper curvature due to heat deformation. According to the invention, a slide positioned in the projection gate of the projector exhibits incorrect curvature, preferably as detected by the autofocus system of the projector, a door is opened allowing dry heat from the projection lamp to be applied directly to the slide, preferably until the slide reverts to a proper or normal curvature.
