ABSTRACT:
A dispenser of film units is operative with a film processing apparatus enclosed within a housing. The housing includes a front sidewall having an exit slot for delivery of film units, the dispenser including a film ejection device located behind the slot for ejecting film units out of the housing via the slot. The ejection device may include rotating pressure rolls which may also serve a function in the film processing. The dispenser includes a catcher constructed of a four-bar mechanical linkage, and includes a spring urging the catcher from an extended state away from the sidewall to a retracted state contiguous the sidewall. The catcher is supported pivotally by a strut assembly which pivots from the sidewall, and connects. A flap interconnects the tray with the sidewall. An articulation pivot permits a folding of the flap against the tray during retraction of the catcher. Force exerted by an exiting film unit overcomes the retractive spring force to deflect the tray to the extended catcher state. A hook assembly in the tray engages side edges of a film unit to hold the film unit flat against the tray and prevent a folding of the flap against the tray. Retraction is inhibited by the presence of the film unit in the catcher, and proceeds automatically by removal of the film unit from the cathcher tray.
