Device for handling photographic film between a cassette and an exposure reproduction apparatus

In a device for handling photographic film for transfer to an exposure reproduction apparatus:

• a film holding cassette having an opening in one side adapted to be placed in registration with an access opening into a housing having exposure reproduction apparatus therein;
• a closure displaceable between open and closed positions relative to said cassette opening;
• a film support having opposite end portions;
• pivot means mounting one end portion of the support in the cassette and with the opposite end portion of the film support aligned with said cassette opening;
• means on said opposite end portion of the support for supporting engagement with a piece of film within the cassette, the film being intended for transfer to the exposure reproduction apparatus;
• and
• means for pivotally swinging said support on said pivot means to project said opposite end portion of the support through the cassette opening when said closure is in it's open position to thereby carry the film through said cassette opening and the aligned housing access opening for handling of the film by the reproduction apparatus.

A device for handling photographic film between a cassette and an exposure reproduction apparatus:

• said cassette having a film passage access opening normally closed by a shiftable closure, and said apparatus including an enclosing housing having an access opening;
• said openings being registrable with the cassette mounted in closing relation to said opening in the housing;
• said cassette having therein a film supporting frame;
• said apparatus including an exposure drum within said housing;
• means including said frame for moving the film from the film supporting frame through the aligned openings into said housing toward said drum;
• film supporting structure on said frame and said drum cooperating for transfer of the film from the frame to the drum;
• means including a rotatable and axially shiftable shaft;
• an actuating handle lever coupled with the shaft for selectively rotating and axially shifting the shaft;
• a guide plate having an angular guide slot therein through which said handle lever extends and by which selective axial and rotary movements of the shaft by actuation of the handle lever are determined;
• and
• means controlled by said shaft for effecting film movement shifting of said frame toward said drum and for driving said drum.

In a device for handling photographic film transferred from a cassette into an exposure reproduction apparatus including a drum within an enclosing housing:

• the housing having an access opening aligned with the drum for registration of a cassette with the opening for transfer of a piece of film shorter than the diameter of the drum from the cassette onto the drum;
• said drum being rotatably mounted within the housing;
• film-engaging pins located at spaced longitudinal intervals in alignment on the perimeter of the drum and engageable in openings in an end margin of a film piece;
• means for rotatably actuating the drum to align said pins with said openings to receive a film piece through said opening from a cassette and for then driving the drum rotatably to draw the film from the cassette unto the drum;
• and
• means for effecting transfer of film from the cassette coordinated in operation with rotatable actuation of the drum.

In a device for handling photographic film for transfer to an exposure reproduction apparatus:

• a film holding cassette having an opening in one side adapted to be placed in registration with an opening in a reproduction apparatus housing access opening;
• a displaceable closure for said cassette opening;
• a film support and means pivotally mounting the support in alignment with said cassette opening;
• means on said support for supporting engagement with a piece of film within the cassette for transfer to the exposure reproduction apparatus;
• means for pivotally swinging said support carrying the film through said cassette opening when said closure is open;
• said support comprising a frame;
• biasing means normally retaining said frame within the cassette;
• said means pivotally mounting the support frame comprising a shaft;
• said means for moving the support frame including a rock lever on said shaft;
• and
• means for driving said rock lever to turn the shaft for rocking said support frame.

A device for handling photographic film between a cassette and an exposure reproduction apparatus:

• said cassette having a film passage access opening normally closed by a shiftable closure, and said apparatus including an enclosing housing having an access opening;
• said openings being registrable with the cassette mounted in closing relation to said opening in the housing;
• said cassette having therein a film supporting frame;
• said apparatus including an exposure drum within said housing;
• means including said frame for moving the film from the film supporting frame through the aligned openings into said housing toward said drum;
• film supporting structure on said frame and said drum cooperating for transfer of the film from the frame to the drum;
• and
• air suction holes arranged in said drum in zigzag pattern grooves extending along the drum.

A device for handling photographic film between a cassette and an exposure reproduction apparatus:

• said cassette having a film passage access opening normally closed by a shiftable closure, and said apparatus including an enclosing housing having an access opening;
• said openings being registrable with the cassette mounted in closing relation to said opening in the housing;
• said cassette having therein a film supporting frame;
• said apparatus including an exposure drum within said housing;
• means including said frame for moving the film from the film supporting frame through the aligned openings into said housing toward said drum;
• film supporting structure on said frame and said drum cooperating for transfer of the film from the frame to the drum;
• means for rotatably driving said drum for withdrawing the film from the frame and the cassette in one direction and for returning the film to the cassette in the opposite direction;
• and
• stripper blade means operative to effect stripping of the film from the drum and guiding of the film for transfer from the drum into the cassette.
