A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel. The channel is formed by a repeating combination of squeegee pinch rollers and impingement slot nozzles. Photographic processing solution is introduced through the impingement slot nozzles and the squeegee pinch rollers are used to remove the processing solution from the photosensitive material and provide transport of the photosensitive material. Solution level control is achieved by drains positioned below the tops of the upturned sections. The slot nozzles and the pinch rollers work interactively to break down the chemical barrier layer.

Cette invention concerne un appareil de développement de photographies à faible encombrement qui met à profit un canal de traitement horizontal étroit. Le canal est formé par une combinaison répétée de galets pinceurs à raclette et de fentes de projection. Ces dernières assurent le mouillage du support photosensible tandis que les galets à raclette le débarrassent de la solution de développement tout en assurant son transport. Le réglage du niveau de solution est assuré par un canal d'évacuation situé à un niveau inférieur au sommet des sections repliées vers le haut. Les fentes de projection et les galets pinceurs coopèrent pour détruire la couche barrière chimique.
