Title:
PHOTOGRAPHIC PROCESSING APPARATUS
Document Type and Number:
WIPO Patent Application WO/1993/011464
Kind Code:
A1
Abstract:
It is known to use rotating drums in photographic processing apparatus. However, in many embodiments, relatively large volumes of processing solution are required for effective operation of the apparatus. This makes most drum arrangements unsuitable for use with unstable chemistry and single use chemistry as the processing solutions need to be replaced frequently. Described herein is photographic processing apparatus which incorporates a drum arrangement to form a low volume processing tank. The arrangement comprises a processing tank (10) in which a central rotatable drum (20) is mounted. A clearance of less than 5 mm is provided between the tank (10) and the drum (20) which defines a low volume for the processing solution (30).
