Abstract

A conveying arrangement in a developing apparatus for photographic material has pairs of conveying rollers as well as guiding and/or deflecting sheets which extend between two opposite sidewalls. Fastening elements are provided on both sidewalls and are adapted to hold the ends of a guiding and/or deflecting sheet against movement in all directions except for an unlocking direction. A removable, deformable locking element is further provided and is adapted to prevent movement of the sheets in the unlocking direction. The fastening element for a guiding and/or deflecting sheet includes a cutout in each of the sidewalls and a positioning pin in at least one of the cutouts. The positioning pin cooperates with an opening in the corresponding guiding and/or deflecting sheet.
