Title: Daylight film handling system
Claims: What is claimed is: 1. Apparatus useful for dispensing film sheets into a cassette, each sheet having a notch extending inwardly from an edge thereof, one at a time from a stack of such sheets, said stack being comprised of alternate odd and even sheets with the notch in all of said odd sheets being aligned in a first row and the notch in all of said even sheets being aligned in a second row, said apparatus comprising: a housing having an exit opening adapted to accommodate said stack therein; first cam means in said housing for engaging said stack in alignment with said first row of notches; second means in said housing for engaging said stack in alignment with said second row of notches; means for alternately disengaging said first and second cam means from said stack to successively release one sheet at a time therefrom through said exit opening; a cassette having an entrance opening for receiving a film sheet therethrough; cassette light shield means disposed in said entrance opening; means on said housing removably engagable with said cassette for opening said light shield means to permit a film sheet released from said exit opening to pass through said entrance opening; said first cam means comprising a first cam member eccentrically secured to a first rotatable rod; said second cam means comprising a second cam member eccentrically secured to a second rotatable rod; and said means for alternately disengaging said first and second cam means including means for alternately rotating said first and second rods. 2. Apparatus useful for dispensing film sheets into a cassette, each sheet having a notch extending inwardly from an edge thereof, one at a time from a stack of such sheets, said stack being comprised of alternate odd and even sheets with the notch in all of said odd sheets being aligned in a first row and the notch in all of said even sheets being aligned in a second row, said apparatus comprising: a housing having an exit opening adapted to accommodate said stack therein; first cam means in said housing for engaging said stack in alignment with said first row of notches; second cam means in said housing for engaging said stack in alignment with said second row of notches; means for alternately disengaging said first and second cam means from said stack to successively release one sheet at a time therefrom through said exit opening; a cassett having an entrance opening for receiving a film sheet therethrough; cassette light shield means disposed in said entrance opening; means on said housing removably engageable with said cassette for opening said light shield means to permit a film sheet released from said exit opening to pass through said entrance opening; and means for preventing release of said film sheets when said cassette is not engaged with said means on said housing. 3. Apparatus useful for dispensing film sheets into a cassette, each sheet having a notch extending inwardly from an edge thereof, one at a time from a stack of such sheets, said stack being comprised of alternate odd and even sheets with the notch in all of said odd sheets being aligned in a first row and the notch in all of said even sheets being aligned in a second row, said apparatus comprising: a housing having an exit opening adapted to accommodate said stack therein; first cam means in said housing for engaging said stack in alignment with said first row of notches; second cam means in said housing for engaging said stack in alignment with said second row of notches; means for alternately disengaging said first and second cam means from said stack to successively release one sheet at a time therefrom through said exit opening; a cassette having an entrance opening for receiving a film sheet therethrough; cassette light shield means disposed in said entrance opening; means on said housing removably engagable with said cassette for opening said light shield means to permit a film sheet released from said exit opening to pass through said entrance opening; and means on said processor removably engageable with said cassette for opening said cassette light shield means to permit a film sheet to be transferred from said cassette to said processor. 4. Apparatus useful for dispensing film sheets into a cassette, each sheet having a notch extending inwardly from an edge thereof, one at a time from a stack of such sheets, said stack being comprised of alternate odd and even sheets with the notch in all of said odd sheets being aligned in a first row and the notch in all of said even sheets being aligned in a second row, said apparatus comprising: a housing having an exit opening adapted to accommodate said stack therein; first cam means in said housing for engaging said stack in alignment with said first row of notches; second cam means in said housing for engaging said stack in alignment with said second row of notches; means for alternately disengaging said first and second cam means from said stack to successively release one sheet at a time therefrom through said exit opening; dispenser light shield means disposed in said exit opening; a cassette having a film sheet entrance opening; cassette light shield means disposed in said entrance opening; means for engaging said cassette and said housing with said exit and entrance openings in alignment; said first cam means comprising a first cam member eccentrically secured to a first rotatable rod; said second cam means comprising a second cam member eccentrically secured to a second rotatable rod; and said means for alternately disengaging said first and second cam means including means for alternately rotating said first and second rods. 5. Apparatus useful for dispensing film sheets into a cassette, each sheet having a notch extending inwardly from an edge thereof, one at a time from a stack of such sheets, said stack being comprised of alternate odd and even sheets with the notch in all of said odd sheets being aligned in a first row and the notch in all of said even sheets being aligned in a second row, said apparatus comprising: a housing having an exit opening adapted to accommodate said stack therein; first cam means in said housing for engaging said stack in alignment with said first row of notches; second cam means in said housing for engaging said stack in alignment with said second row of notches; means for alternately disengaging said first and second cam means from said stack to successively release one sheet at a time therefrom through said exit opening; dispenser light shield means disposed in said exit opening; a cassette having a film sheet entrance opening; cassette light shield means disposed in said entrance opening; means for engaging said cassette and said housing with said exit and entrance openings in alignment; and means responsive to said engagement of said cassette and housing for opening said dispenser light shield means and said cassette light shield means. 6. The apparatus of claim 5 including a plate adapted to bear against said stack; and spring means coupled to said plate for resiliently urging said stack against said first and second cam means. 7. The apparatus of claim 6 including at least one arm positioned to bear against said stack for retaining said stack against said plate. 8. The apparatus of claim 7 wherein said means for engaging said cassette and housing includes a tray adapted to hold said cassette and mounted for movement toward and away from said housing; and means responsive to said tray moving said cassette into engagement with said housing for lifting said arm from said stack.
