Abstract
Abstract A sheet film processing apparatus for sheet film including a housing for holding a re-loadable film, and having an upper surface and a back surface, developing equipment including developing tanks with developing fluid, arranged above the upper surface, a housing cover for covering the developing equipment in a light impervious manner, elements for leading the film to the developing device, a fluid collector basin located between the developing tank and the upper surface for catching any developing fluid which may fall from the developing equipment, a waste water tank provided at the back surface, and a plurality of drain hoses connecting the tanks and the collector basin with the waste water tank so as to lead the developing fluid to the waste water tank. This leads to a particularly compact construction which is easily accessible for servicing.
