The present invention relates to still cameras, and more particularly to an improved apparatus for processing sets of photographic film,
In Belgian Patent No. 618,154, a photographic apparatus in the form of a camera has been described comprising two pressing members between which an assembly of film is advanced, in order to effect the distribution of a treatment fluid to the body. inside of the film set.

   Manual removal of a film assembly from a camera, such as this type of camera, to and between two roller-shaped pressers and directly from the camera poses the problem of guidance. of the film assembly, during its removal, between the pressure rollers. The pressure rollers are generally arranged so that their axes are in the same plane; once the film assembly is within the nip of the rollers, it can only be moved in a direction perpendicular to the axes of the rolls.

   Film assemblies of the type generally used in such apparatus generally have side edges which extend over most of their length and which are substantially straight and parallel! so that when the film assembly is to be removed without damage or mutilation, the film assembly should be oriented, during its removal movement between the pressure rollers, so that these side edges are perpendicular to the aforementioned plane,

     that is, so that its edges are parallel to the direction of travel of the film assembly

The present invention is useful in still photographic apparatuses such as cameras, in which an assembly or element of film is moved in the camera towards two pressure rollers and between them and is extracted directly from the cambra at the location of the rollers. ,

   under the effect of a tensile force applied manually to a leader attached to the assembly or element of film. The rollers come into contact with the film element and apply pressure thereto, so as to distribute a liquid treatment composition in contact with this element.

   The direction of movement of a film member held in the nip of the nip rollers is obviously perpendicular to the axes of the rollers so that the member or assembly of film, which is usually rectangular in shape, must be oriented during this movement. removal, so that its lateral, linear and parallel edges are substantially parallel to the axes of the rollers, in order to prevent mutilation of the element, due to contact of said lateral edges with parts of the rollers. the device.

 film between the rollers, so as to act on the side edges of the film assembly, so as to align and convane it, with respect to its direction of movement.



   Before exposing a set of film and removing it from the camera between the pressure rollers for processing, the cover sheet 76 is removed by pulling the leader 78 through the opening 112 until this leader detaches from the cover sheet, which advances the front end portion of this sheet between the pressure rollers and into the opening 110 where it can be grasped to remove it from the camera.



   Another kind of guide device, bearing the reference 140, according to the present invention is illustrated in FIG. 9. The guide device 140 has a structure similar to that of the guide device shown in FIGS. 6 to 8 and comprises a guide bar 142 and the two aforementioned guide members 144. The guide bar and the guide members are shown as constituting parts of a single element, but it goes without saying that the guide bar and the guide members guide can be constituted by three distinct elements, as illustrated in FIG. 8 and in this case, the guide bar 130 and the guide members 134 can constitute a single element similar to the guide device 140.

   The guide 140 is mounted on the front section of the housing 88 near the front roller 114 so that the end rear surfaces of the guide members 144 lie approximately in a plane tangential to the surfaces of the rollers 114 and 116. between rollers 114 and 116 is slightly greater than the width of the leader 70 but is less than the narrowest part of the decreasing width end section 20, so that the leader 70 can pass between the guide members 144,

 <Desc / Clms Page number 23>

 while the terminal section of decreasing width 20 * and supported and guided by the members 144 between the pressure rollers,

     The intermediate section of the guide bar 142 and the guide members 144 cooperate with each other and with the roller 114 to define what may be called a passage through which the leader 70 is guided to the front of the roller 114. and in the opening 112,
The width of the film removal passage 110 in the lower end wall of the camera housing is generally equal to the width of the film assembly, while the width of the opening 112 suffices. either suffi-,

  ante to let the primer pass 70. It is best to let only one primer at the roof come out of the camera where it can be grabbed and this feature is desirable to prevent the operator from pulling the primer. inadvertently wrong primer or pulling more than one primer to the liver. For this purpose, a recess 146 has been made in the end wall 103, near the opening 112, to contain the end sections. before 80 of the primers 70.

   These front end sections, primer $ 70 are folded over themselves, and each front end section is releasably glued to the primer of the film set preceding it, the front end section 80 of the first film set. (the one to be exposed) being attached to the primer 78. The folded forward end sections of the primer 70 are contained in the recess 146 which is provided with an elastic cover 148.

   When the leader 78 (or a leader 70) is removed through opening 112, the front end section 80 of the next bite 70 unfolds and comes out of the recess 146 where it can be grasped for pulling. The leader out of the camera * With this arrangement, only one leader at a time leaves the recess 146 in position to be grasped and removed. A convenient means of loosely attaching each forward end station 80 to the primer preceding it has been illustrated, and it consists of:

 <Desc / Clms Page number 24>

 by an opening 82, which is formed in each primer 70 near its front end section 80 and in the primer 78.

   A piece of pressure-applied adhesive tape is affixed to the primer to the right of opening 82, so that the adhesive surface of the roof tape contacts the front end section 80 of the next primer passing through the opening. 82,
When a photosensitive sheet 12 is pulled inside a film-pack around the curved end 60 of the press plate superimposed with a second sheet 14, the latter tends to be displaced, for example due to friction between the various materials constituting the sheets.

     Devices have been provided in the camera to prevent the second sheets 14 from performing such movement and, in the embodiment shown, they include a long bar 150, which is hinged between its ends in a housing 152. mounted on the rear wall 104 in the chamber 108. The bar 150 is urged by a spring 154 to a forward position, in which its end sections 156 extend forward in line with portions of the removal passage 56 formed in the. loader 42, towards the guide members 134 and against them.

   In this position the end sections 156 bear against the leading edges of the second digs 14 near their sides, in order to prevent the second leaves from being moved to the near-stroke rollers. The spring 154 is strong enough to oppose the low force exerted by the second sheets due to their friction against the other sheets, but it allows the bar 150 to pivot sufficiently back so that a second sheet 14 can be removed when it is pulled out of the charger superimposed with a photosensitive film 12,

   The aforementioned U-shaped opening 66 made in the rear wall 54 serves to receive a small box 152, a part of which extends into the magazine 42 passing through the opening 66,

 <Desc / Clms Page number 25>

 
To process a set of film after exposure of this set to the camera the operator need only grab the primer 70 of the set of film, which protrudes out of the wedge, and apply traction to this primer, until it loosens from the film set.

   During the bait removal or withdrawal movement, it is not necessary to take special precautions to ensure that the leader is pulled exactly in the desired direction * When the leader has come off, the opera * tower salted the narrowed * end * of the film assembly was, * which during the extraction of the primer was advanced between the pressure rollers and exited from the camera to an extent capable of gripping said end 20, by applying traction to the end in question,

   so as to remove all of the camera film between the pressure rollers.



   Also in this case no special effort is required to secure the removal of the film assembly in a particular direction since the direction of the removal and the orientation of the assembly. of film during this movement are determined as soon as the film assembly is gripped by the pressure applicator rollers, ie immediately after the resumption of the removal movement. During the interval between the two removal phases,

   forces are exorcised on the film assembly in the casera housing to properly orient the film assembly relative to the direction of removal between the rollers. :
It is obvious that the invention is not exclusively limited to the details described above and that many modifications can be made 'these details without departing from the scope of the invention, as defined in the resells. following tbns,
