  • the last frame of the film strip 12 After the last frame of the film strip 12 is exposed, it may be rewound in the camera in a well known manner thereby permitting the removal of the film assemblage 10 from the camera without risk of further exposing the film strip 12.
  • the projection 15 prohibits the leading edge 17 of the film strip 12 from being rewound into the cartridge 34, thereby permitting its subsequent withdrawal in a manner to be herein described.
  • the user may then grasp the pull tab 48 so as to forceably remove it from the canister 34.
  • Such removal need not be particularly difficult since the pull tab 48 may only be retained to the cartridge 34 by way of the frictional engagement between the tangentially extending lip portions 44 and 46 and the pull tab opening 50.
  • a frangible adhesive could be utilized to connect the pull tab 48 td the cartridge 34 during exposure.
  • the user may then insert the film assemblage 10 into the photographic processing apparatus 11 by way of the access door 64.

  • the frame member 92 is actuated by the solenoid 98 to translate outwardly from the base block 61 thereby separating the distance between the rollers 88, 90 so as to define a gap therebetween in order that the rollers 88, 90 become ineffective in applying pressure to the exposed filmstrip 12 as the film strip 12 is withdrawn from its cartridge 34.
  • Closure of the access door 64 may operate by way of the control circuit 101 to actuate the motor 76 which in turn drives the sprocket wheels 70, 72 by way of interconnecting gear train 78 and drive chain 74. In this manner, the exposed film strip 12 may be entirely withdrawn from its canister 34.
  • the leading end 17 enters the film receiving chamber 80 by way of the inlet opening 87 and is thereafter grasped between the outside edge of the wiper member 86 and the inside surface of the film receiving chamber 80 (see Fig. 8) so as to continue the forward movement of the leading end 17 of the film strip around the cylindrical chamber 80 in a manner as is more fully taught in U. S. Patent No. 3,377,936 entitled “Easy Loading Apparatus For Film Supply For Photographic Cameras", issued April 16, 1968.
  • the flexible wiper member 86 automatically reduces itself in outer diameter.
  • the pod 26 of processing composition is ultimately withdrawn through the opening 42 by bending over that portion of the side wall 40 between the slits 56 and about the fold line 54 as previously described.
  • the photodiode 100 thereafter senses the trailing end 19 of the exposed film strip 12 (see Fig. 7) so as to signal the motor 76 by way of the control circuit 101 to reverse its direction of rotation while simultaneously actuating the solenoid 98 to cause the frame member 92 to move toward the base block 61 thereby moving the pressure applying rollers 88, 90 into juxtaposed position with each other to establish a roller bite therebetween.
  • Frame member 92 may additionally support a heater element 112 which is complementary to the spaced apart strips 22, 24 of the heat activatable adhesive so as to effectively activate the adhesive strips 22, 24 when the frame member 92 is moved to its position closely adjacent the base block 61 as shown in Fig. 6.
  • the heater element 112 may also be activated by way of the control circuit 101.
  • Reversing the rotational direction of the motor 76 reverses the rotational direction of the sprocket wheels 70, 72 so as to. advance the film strip 12, trailing end 19 first, in a direction generally opposite to the given direction in which the exposed film strip 12 was previously withdrawn from the cartridge 34.
  • Advancement of the exposed film strip 12 past the heater element 112 operates to activate the spaced apart strips 22 and 24 of adhesive so as to bond the longitudinal edges of the two superposed sheets 14, 16 of photographic material together immediately prior to the application of pressure to the film strip 12 by way of the rollers 88, 90.
  • the rollers 88, 90 thereafter exert a compressive force against progressive incremental sections of the film strip 12 containing the recorded images as it is advanced from the chamber 80 by the sprocket wheels 70, 72 to facilitate the rupturing of the pod 26 of processing composition and the spreading of the processing composition 27 between the superposed sheets 14, 16 in correspondence with film advancement through the pressure applying rollers 88, 90.
  • the trailing edge 19 of the exposed and processed film unit 12 is thereafter advanced by way of the deflecting plate 110 into the inlet opening 106 of the imbibition chamber 104 from which it ultimately exits from the housing 62 by way of the outlet opening 108 after a sufficient duration has elapsed to allow the exposed and processed film strip 12 to develop a viewable image in the aforementioned manner.
  • the viewable images provided by the exposed, processed and developed film strip 12 may be viewed by transmitted light and thus are categorized as transparencies. Such transparencies may thereafter be cut from the film strip 12 and mounted in frames suitable for insertion in a slide projector as is wil known in the art. In this manner the photographer may process his own slide transparencies at home in an economical and efficient manner so that they may be viewed immediately after the last frame of the film strip 12 is exposed.
