AUTOMATIC DEVELOPING DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent the inflow of the air in a processor into an image exposure device which attracts and holds a photosensitive material from an insertion port by a negative pressure. SOLUTION: An outflow preventive device 90 has a chamber 92 arranged near the upper side of guides 82 of a transporting device 74 and is projectingly provided with a nozzle 98 facing the insertion port of the processor 12 from this chamber. The outflow preventive device ejects the air sent into the chamber by the operation of a blast fan 96 toward the insertion port from an ejection port 100 formed at the nozzle. As a result, the outflow of the air in the machine frame from the insertion port may be surely prevented without hindering the passage of the photosensitive material.
