The front-filling system consists of a pair of fill buckets located on the front of the processor housing. The fill buckets are connected to the internal solution tanks by fill tubes such that fluid in the fill buckets will be delivered to the solution tanks as solution is added during filling or replenishment. The fill buckets are provided with movable lids, to minimize evaporation and accumulation of debris, and the fill buckets are physically separated to prevent cross-contamination during the filling process. The fill buckets, or portions thereof, may be made of transparent material to aid in observing solution levels and solution condition. The fill buckets are positioned and sized to allow for easy filling and replenishment, and for easy observation of solution levels and solution condition without removal of top lids or top housings. The fill buckets each have front over-flow sluices, to eliminate any possibility of overflow within the interior solution tanks.

Solution filling system for a film processor apparatus

A switching system consists of a pressure sensitive floor pad containing internal, sealed electrical contacts, and solid-state electronic timer and associated circuitry. The floor pad is positioned so that an operator must step on the pad in order to feed film into a film processor apparatus. When an operator steps on the pad, an electric circuit is completed, which causes the film processor apparatus to automatically switch from a 'stand-by' mode to a 'run' mode, without requiring an operator to remember to activate any switch and without any need for film-sensing devices. After the operator steps back off the floor pad (after having fed one or more films into the apparatus), the electronic timing circuit continues the operation of the processing cycle for a time period sufficient to insure that any film inserted is fully processed. Because the timer does not start timing until after the last film has been introduced into the processor, no film can remain in the processor when the processor is returned to its stand-by mode. When the timer times out, the electronic circuitry automatically returns the apparatus to the 'stand-by' mode.

Switching system for a film processor apparatus

A film processor is provided with a top-drop film system which, in the perferred embodiment includes a slot in the top housing cover of the processor, an inclined-plane film guide directly beneath the slot, and a pair of opposing rollers positioned at the bottom edge of the film guide. The top-drop slot allows films to be dropped into the processor, rather than hand-positioning and hand-feeding each film. The specific roller locations and film guide angle allows films to be fed into the processor automatically and consistantly without 'snapping' or over-bending, and without need for operator presence or attention. The inclined-plane film guide is designed for easy removal for cleaning. The guide is mounted in precise-angle slots to maintain angle consistency. The extra width of the top-drop slot allows panoramic films to be processed in a sideways configuration, thereby increasing processing speed by 30% over comparable prior art devices.
