| description | Microfilm is inserted between two or more parallel, transparent, laterally invertible support plates placed in a light path emanating from a light source and travelling to a projection objective. The plates are placed in a tray which can be slided in two directions normal to the light path.

For reading the microfilm located on the other side, the plates are inverted in order to bring this film in proper reading position. |
