Definitions

  • This invention relates to apparatus for processing rolls of 35mm transparency film.
  • the present invention relates to apparatus for processing a roll of 35mm transparency film and, more particularly, to such apparatus which is compact, inexpensive, easy to use and especially attractive to the amateur photographer who desires to process his own film.
  • U.S. Patent Nos. 4,309,100, 4,307,955, 4,272,178, 4,212,527 and 4,167,318 show film processing apparatus which are adapted for use in the processing of rolls of 35mm transparency film. Also, see pages 53 and 54 of RESEARCH DISCLOSURE, dated January 1981. While these apparatus have desirable features, they do not provide for low cost and ease of operation. For example, the apparatus disclosed in the U.S. patents, with the exception of the one taught by U.S. patent 4,167,318, require a cutter for severing the film from its attachment to its film spool, thereby adding to its cost. Further, only the apparatus of U.S.
  • patent 4,307,955 recognizes the advantages of simplicity of loading, the apparatus being designed for use with a processing kit. Still further examples are the apparatus described in U.S. patent 4,212,527 which includes an extendable dark chamber for receiving the film after it has been treated with a processing composition, thereby adding to its cost and overall size.
  • the apparatus described in U.S. patent 4,167,318 is rather large in comparison to the size of the film cassette used therein. Its operation requires the complete removal of the film from the film cassette before it can be processed. This adds to the cost of the apparatus as it requires. a control circuit for the detection of the trailing end of the exposed film with its associated container of processing composition.
  • the invention is based on an apparatus for processing a roll of film coiled on a spool in a cassette by means of a kit positionable into the apparatus, the kit comprising a housing, a container of processing liquid, a processing liquid dispenser cooperating with the container and a roller supporting a strip of sheet material, wound upon said roller, the apparatus comprising: a housing having means for retaining the kit such that a free end of the sheet material may be joined with a free end of the film, the housing of the apparatus including a door movable between open and closed positions.
  • the apparatus of the invention automatically protects the film before and during processing by locking, the loading door of the apparatus in its closed position to insure the lighttightness of the apparatus before the film is withdrawn from its cassette and during its processing; and, withdrawal of the film from the cassette is prevented until the processing liquid is ready to be used in the process.
  • the apparatus is manually operable, rather than by an electrical motor.
  • the invention relates to apparatus for processing a photographic film assemblage of the type which includes a film cassette containing therein a roll of 35mm transparency film.
  • the film cassette is preferably configured to be readily insertable into a conventional 35mm still camera.
  • the apparatus includes a lighttight housing having a loading door which is pivotally mounted for movement between open and closed positions.
  • the housing is constructed to receive a film processing kit which comprises a housing of two sections movable between open and closed positions, a roller having a length of flexible sheet material wound thereupon, a container of processing liquid, and a dispenser.
  • the apparatus also includes structure for supporting a film cassette containing a roll of exposed film, and a take-up roller which receives the free ends of the sheet material and the film to wind in superposition onto the take-up roller.
  • a gearbox containing a power transmission system including a plurality of gears, clutches and drives.
  • One of the drives is adapted to drive the take-up roller during a processing operation while the drive is disconnected from the film spool and the roller of the sheet material.
  • two of the drives are adapted to drive the film spool and sheet material roller during a post processing operation while allowing the take-up roller to freewheel.
  • the apparatus further includes a rack and sector gear arrangement which incorporates a lost motion feature.
  • a rack and sector gear arrangement which incorporates a lost motion feature.
  • the sheet material As the sheet material is unwound from its spool, it passes beneath the dispenser where a coating of the processing liquid is applied to a gelatin coated surface of the sheet material. That coated surface is then moved into engagement with the emulsion side of the exposed film and directed between a pair of pressure applying rollers to form a laminate which is subsequently wound upon the take-up roller.
  • the laminate remains wrapped upon the take-up roller for a period of time sufficient to form visible images in the laminate, preferably on the film.
  • the operator rotates the lever in an opposite direction to its original position.
  • Such rotation moves the roller out of the kit and the rack forwardly into its original position.
  • the rack During forward movement of the rack its arm moves the one housing section of the kit into closing relation with the other housing section as the roller moves out of the kit.
  • the rack unlatches the loading door and shifts the power transmission system so that any power input from the crank is transmitted to the sheet material roller and the film spool rather than to the take-up roller.
  • the crank is rotated in the same direction as during the processing operation.
  • the rotation drives the sheet material roller and the film spool in directions which unwind the laminate from the take-up roller.
  • the film is stripped from the sheet material and both are rewound upon their spool and roller, respectively. Thereafter the loading door of the processor may be opened, the kit containing the used sheet material and any residue of the processing operation may be removed and safely discarded, and the processed film may be removed from its cassette. The individual frames of the processed film may then be cut and mounted in frames for viewing.
  • Figs. 1 and 2 show a preferred form of apparatus 10 for processing a roll of exposed film the film preferably being of the 35mm transparency film.
  • the apparatus 10 comprises a housing 12 having a loading door 14 pivotally coupled at one end by a pair of pins 16 (only one shown) which extend outwardly from opposite side walls 18 and 20 of the housing 12 and are received by apertures 22 (only one shown) in the loading door 14. Movement of the loading door 14 into its closed position (Fig. 2) renders the housing 12 lighttight.
  • a generally planar support 24 extends between the side wall 18 and a side wall 26 of a gearbox 28.
  • the support is provided with a first opening 30 through which a spring-biased plate 32 extends, a second opening 34 through which a portion of a roller 36 penetrates, and a third opening 38 through which a portion of a take-up roller 40 extends.
  • the roller 36 and the take-up roller 40 are mounted for rotation about their axes by means not shown.
  • the apparatus 10 also includes means for locating a film processing kit 42 into its proper position relative to other elements of the apparatus 10. These means include an L-shaped flange 44 which extends inwardly from the side wall 26, an arm 46 which extends at a right angle to a rack 48 (Fig. 4), a pair of cams 50 (only one shown) located adjacent opposite sides of the horizontal support 24, and a plate 52 which extends along the side wall 18.

  • the first section includes a top wall 58, an end wall 60, and a bottom wall 62.
  • the end wall 60 (Fig. 2) includes a passageway 64 formed by a generally horizontal flange 66 and a vertical flange 68 for receiving the arm 46 of the rack 48.
  • the bottom wall 62 which has a length slightly less than half that of the top wall 58, includes a laterally spaced pair of fingers 70 and 72 the ends of which are provided with tapered latching members 74 and 76, respectively.
  • the second section 56 includes a pair of side walls 78 and 80 interconnected at one end by an end wall 82.
  • a gently curving wall 84 extends between the side walls 78 and 80 and slopes downwardly from the top of the end wall 82 to a point where it terminates in a generally vertical wall 86.
  • Two flanges 88 and 90 extend from the side wall 78 to a point where they are interconnected by a wall 92 (Fig. 6a).
  • the wall 92 has a U-shaped opening 94 therein.
  • a pair of resilient fingers 96 and 98 integral with the wall 92, extend into the U-shaped opening. The fingers 96 and 98 may be spread apart so that the end of a roller 100 can be pushed between them into the U-shaped opening 94.
  • Two flanges 102 and 104 extend from the opposite side wall 80 to a point where they are interconnected by a wall 106 having a U-shaped opening (not shown) therein for receiving the opposite end of the roller 100.
  • the roller 100 has a pair of annular flanges 108 and 110 which may be positioned between the walls 92 and 106.

  • a processing liquid dispenser 116 mounted in the second section 56.
  • the dispenser has a nozzle 118 and a pair of laterally spaced flanges 120 and 122 which restrain sidewise movement of the sheet material 112 as it passes beneath the nozzle 118.
  • the nozzle 118 has a length which is less than the width of the sheet material 112 and is approximately equal to the distance between laterally spaced sprocket holes in a strip of 35mm film, i.e. 2.5 cm.
  • a container 124 having a rupturable end 126 is supported on the wall 84, e.g., by adhesive tape 128.
  • the container 124 holds a supply of viscous processing liquid 130 in a quantity sufficient to coat substantially the entire length of the sheet material 112.
  • Flanges 132 extend inwardly from the bottom of the side walls 78 and 80 (only one shown). They function to guide the lateral edges of the bottom wall 62 as the second section 56 is mated with the first section 54 for closing the kit 42.
  • a recessed area 134 extends around portions of the side walls 78 and 80 and the end wall 82 and cooperates with the tops of the flanges 88, 90, 102 and 104 to receive the edges of the top wall 58.
  • the latching members 74 and 76 are first squeezed toward each other by two flanges 136 (only one shown) which respectively protrude from the side walls 78 and 80.

  • a gear 172 is mounted on a shaft 174 for limited axial movement between a first position wherein it is in drivable engagement with the second power path and a second position (shown in Fig. 5) wherein it is in drivable engagement with the first power path.
  • the gear 172 is normally biased into engagement with the gear 158 and may be moved in the direction of the arrow 176 into engagement with the gear 162 by a bell crank 178.

  • a clutch 190 is coupled between the gear 166 and its drive member 188 to allow slippage therebetween when the roller 100 and film spool 144 are driven, to compensate for differences in the increasing diameters of the roll of sheet material 112 and of the film 142.
  • the gear 168 is mounted for limited linear movement along its shaft 192.
  • the gear is biased out of engagement with the gear 166 when the take-up roller 40 is driven and it may be moved in the direction of the arrow 194 into driving engagement with the gear 166 by a cam 196 on the side of the rack 48 as will be explained.

  • the rollers 36 and 272 press the gelatin coated surface of the sheet material 112 into engagement with the emulsion side of the exposed film 142 to form a laminate comprised of a layer of processing liquid 130 sandwiched between the sheet material 112 and the exposed film 142.
  • the laminate is then wound upon the take-up roller 40.
  • the sheet material 112 and/or the film 142 have been completely uncoiled from their respective supports, but not detached therefrom, the resultant increase in tension in the laminate is automatically fed back to the crank 198 thereby signaling the operator to stop rotating the crank 198.
  • a slip clutch 294 may be coupled between the shaft 174 and the crank 198 so that further rotation of the crank 198 by the operator is not transferred to the shaft 174.

  • the rotation immediately drives the rack 48 forwardly toward the take-up roller 40 while moving the first section 54 of the kit 42 back into closing relationship with the second section 56.
  • the initial rotation of the lever 238 is not transferred to the rupturing mechanism 252 because of the lost motion connection; the mechanism 252 is moved, however, by an edge 298 of the top wall 58 of the first section 54 engaging the undersurface 296 of the mechanism and pivoting it upwardly until the left side of the aperture 248 engages the pin 250 and completes the movement of the rupturing mechanism 252 out of the kit 42 before it closes.
  • An edge 298 of the bottom wall 62 of the first section 54 is beveled to cooperate with a radius 300 on the spring biased plate 32 so as to urge the plate 32 downwardly so that the edge 298 may pass to a point where the bottom wall 62 seals the nozzle 118.
  • Movement of the rack 48 to its forward or post processing position shown in Fig. 3 also results in clockwise rotation of the bell crank 178 due to the cam slot 222 and cam follower 218 relationship.
  • the end 206 of the arm 204 pivots out of latching relation with the lip 208 and the U-shaped section 224 moves upwardly into contact with the gear 172, the cam surface 226 of section 224 moving the gear 172 out of engagement with the gear 158 and into engagement with the gear 162.
  • the crank 198 When the lever 238 has reached its post processing position, the crank 198 may be rotated in the same direction as before, i.e., in the direction of the arrow 292.
  • This power input is directed to the second power path through the gear 172 thereby rotating the sheet material roller 100 and the film spool 144 in a clockwise direction (Fig. 5).
