Definitions

  • This invention relates to a device for use with a camera, adapted to stack film sheets, wherein the film sheets after being exposed are transmitted over a curved path to the inlet opening of a receiving magazine.
  • An object of the present invention is to improve existing devices.
  • Another object is the provision of a device which will place film sheets in a magazine in the order in which they were photographed.
  • a slide which moves in the guide of a rotatably mounted angular member and which receives a combined longitudinal and rotary movement from a crank driven by a shaft.
  • FIG. 1 is a longitudinal section through a portion of a film stacking device with attached magazine, which includes the subject matter of the present invention.
  • FIG. 2 is similar to FIG. I but shows the device in a different operative position.
  • FIG. 3 is a perspective view of the device.
  • the illustrated film stacking device includes the usual arrangement of two amplifying screens 1 and 2 constituting the exposure area.
  • An X-ray film 3 is located between the screens 1 and 2.
  • a transporting wheel 4 cooperates with a counterpressure roller 5 for withdrawing the film 3 out of the exposure area between the screens and moving it against a fixed guide 6.
  • the guide 6 has an approximately cylindrical surface, the curvature of which is substantially equal to that of the outer surface of the wheel 4. During this movement the film is bent to the extent of nearly 90 and is introduced into the receiving magazine 7, the longitudinal direction of which extends substantially at right angles to the surface of the film when it is located in the exposure area between the screens 1 and 2. During its insertion into the inlet opening of the magazine 7 the film is guided by guide plate 8.
  • a tubular shaft 13 is rotatably mounted between the sidewalls of a casing and has at one end, or at both ends, recesses for receiving a slide 9.
  • a separate angular member or cube I2 is located inside the tube and is provided with a slit for guiding the slide which can reciprocate in the slit.
  • the slide 9 and the cube I2 constitute the rotary member described in the claim.
  • One end of the slide 9 extends downwardly through a rectangular opening 15 provided in the guide plate 8, while the other end of the guide is rotatably mounted upon a crank 11.
  • the crank 11 is driven by and forms a part of a shaft mounted in the sidewalls of the casing.
  • One end of the shaft projects out of the casing and carries the friction wheel 10.
  • suitable drive engages the wheel I0 and causes the shaft to make I revolution during each feed, namely, every time a film sheet 3 is introduced into the receiving magazine 7.
  • FIG. 1 shows the position of the slide 9 directly after a film sheet has been removed from the exposure field between the screens 1 and 2 and has been inserted into the magazine 7.
  • a new film sheet 3 has been exposed and must be also introduced into the magazine 7 by rollers 4 and 5. Before the front edge of this new film sheet 3 has reached the upper edges of film sheets 14 already located in the magazine and, as
  • the shaft 13 has been turned clockwise to such an extent (Fl 3) that the slide 9 will engage the upper edges of the package of film sheets 14 and will shift them to the left (looking in the direction of FIG. 2), thereby pushing them to the side and providing free entry for the new film sheet 3.
  • the crank II is further rotated and causes the withdrawal of the slide 9, so that the edge of the film package is freed.
  • the new film sheet 3 will drop completely into the magazine and the device will return to the position shown in FIG. I.
  • the receiving magazine can be located in a different position than that illustrated, in relation to the exposure field between the screens 1 and 2.
  • the magazine can be located below the field and substantially parallel thereto. Then the film sheets will have to be curved to the extent of about and the guide 6 will be correspondingly lengthened.
  • a device in accordance with claim 1 comprising a guide plate extending close to said inlet opening for guiding a film sheet through said inlet opening, said guide plate having an opening receiving said slide when a film sheet is being exposed.
  • a device for stacking film sheets for use with a camera comprising in combination with a film exposure area, a magazine having an inlet opening, a guide plate having an opening located adjacent said inlet opening, a slide located adjacent said inlet opening and means moving film sheets individually from said exposing area into said magazine and simultaneously actuating said slide to move it during film exposure into the opening of said guide plate to cover said inlet opening and during the approach of an exposed sheet to move it out of the opening of said guide plate into said inlet opening and move aside film sheets already located in the magazine to facilitate passage of said exposed sheet into the magazine.
  • said means comprise a rotary cube having a slit, said slide being slidable in said slit, and a driving shaft having a crank connected with said slide.
