Abstract
A reproduction camera comprising an original plane, an objective plane, and a picture plane, a raster, a film, and a preferably transparent recording sheet being situated on a glass plate in the picture plane, and a rubber cover optionally being situated on the recording sheet during a reproduction. The recording sheet is preferably adhered along one side to the glass plate therebelow. Static electricity may, however, occur when a rubber cover in a pivotably mounted lid has been pressed towards the adhered recording sheet and is subsequently opened. The attractive force between the cover and the recording sheet caused by the charge may become so strong that the recording sheet follows the lid when said lid is opened. In addition the operator can be subjected to electric shocks. These problems have according to the invention been solved by the preferably transparent recording sheet being made electrically conductive, and by discharging the recording sheet when the rubber cover is removed from said recording sheet.
