PURPOSE: To enable prevention of defective finishing of a film by providing a detecting means which detects that the 2nd and succeeding tracks are not ready to accept the film.

CONSTITUTION: The rear end of a cut film F passes through the inside of a notch 56 and moves to a film delivery port. The end of the turning operation is detected as the projection 51D of a rotary plate 51 actuates a switch 58 for detecting rotation. The film F moved to the film delivery port of the notch 56 is delivered by the driving force of a driving means 52B brought into press contact with a drum 25A by a solenoid (not shown in figure) until the front end thereof is detected in the outlet part of a temporary storage part 20. The film is thus subjected to a developing process. The operation such as emission of an alarm by interrupting the film feeding operation is accomplished when a control part 70 outputs a signal for inhibiting the turning of a reel at the point of the time when the operator depresses a developing switch.
