ABSTRACT A FILM PROCESSOR A photographic film processor comprises six juxtaposed processing tanks (10 to 15), a rack mechanism (16) in each tank (10 to 15) operable to circulate the film within processing solution in the respective tank (10 to 15) for a certain time. A switch mechanism (17) operable to direct the film from being circulated at the end of that certain time and to direct it to a transfer mechanism (18) by which it is passed to the rack mechanism (16) of the next tank (10 to 15) for circulation in that tank. The penultimate tank (15) is a washing tank and there is a transfer mechanism (40) for transferring the film from that washing tank (15) to a dryer (43) which is the last processing station. The film is driven for circulation within and for transfer from one to the next of the six tanks by a first motor (32) which drives a common shaft (20). A clutch (35) couples or decouples the common shaft (20) to a shorter coaxial shaft (36) by which the film is circulated within the washing tank (15). Another clutch (41) couples the shorter shaft (36) to another slower motor (42) when it is decoupled form the common shaft (20) by the clutch (35) so that (15) independently of circulation of film in the other five tanks (10 to 14) and is transported out of the washing tank (15) and transferred to the dryer (43) at a speed which is slower than that of which it is circulated on and transferred between the first five tanks (i.e. 10 to 14).
