Method of and apparatus for controlling the application of processing fluid |
摘要 |
A method of an apparatus for insuring application of a preselected amount of processing fluid to photographic film material are disclosed. A weight sensing device weighs a container of the fluid and permits pumping of the fluid if there is an adequate amount of fluid contained in the container. A magnetic sensing arrangement also effects reversal of the pumping after a preselected length of material has had fluid applied thereto. At the completion of fluid application, the fluid is evacuated from the nozzle.
