A record processor employing a novel developing system, toner module and method in which a quantity of toner fluid is held adjacent to an electrostatic latent image on a film, in a substantially quiescent state, for a sufficiently long period to insure migration and adherence of toner particles to the image, is disclosed, wherein a set small quantity of fluid is drawn into a development chamber formed adjacent to the film which chamber is sized and shaped so as to facilitate the fluid reaching a relatively quiescent state quickly and which fluid is held in the chamber by a natural meniscus dam at a sharp edge formed across the flow path of the toner.

Method and apparatus of aperture flooding

Disclosed is a copyboard cover for covering and holding in position documents placed upon a copyboard of a photographic copying machine. The copyboard cover in its preferred embodiment includes a frame, means for reciprocating the frame to and from a load position uncovering the copyboard for placement of a document on the copyboard and a copy position covering the document and the copyboard, a light-blocking cover material for covering the copyboard when the frame is in the copy position to block out undesirable light, a pressure plate mounted within the frame for holding the document flat against the copyboard, and means for reciprocating the pressure plate towards the copyboard in response to the frame moving into the copy position and from the copyboard in response to the frame beginning movement back to the load position. In the preferred form of the copyboard cover, the light-blocking cover material is provided by a flexible, wide belt which is moved over the document on the copyboard without relative movement between the document and the portion of the belt in contact with the document.
