Document reproduction camera with integral dark chamber - has lens carrier and document support displaced along same vertical axis

摘要

The reproduction camera has an integrated dark chamber and automatic focussing as well as a developing system. The camera has an objective lens support and a document support which are displaced on the same vertical translation axis. This ensures faithful reproduction of the document on a sensitive support via the lens and an inclined high reflection mirror. The document support has at its rear end guide pads which slide along vertical fixed axes. The document support consists of two horizontal slides and a horizontally movable drawer. This drawer has a cavity in it in which the documents are placed. The drawer has an hinged cover which has on its lateral aides a ramped cam. The cam cooperates with a roller fixed to an housing. This system ensures that the document is placed flat in the bottom of the cavity and automatically ensures optical parallelism.
