Definitions

  • the present invention relates to an apparatus for manufacturing photographic filmstrips from a long strip of photographic film, especially for manufacturing photographic filmstrips having one or two perforations and data per picture frame along one or both of lateral sides thereof by perforating, data recording and cutting the long film.
  • Leader-advancing type photographic film cassette have been disclosed, e.g., in U.S.P. No. 4,846,418, in which the whole length of a filmstrip is contained within a cassette shell, and a film leader of the filmstrip can be advanced to the outside of the cassette shell by rotating a spool of the cassette.
  • a camera need not have such a sprocket wheel that has conventionally been used for feeding the film leader to the take-up spool of the camera.
  • the filmstrip may be advanced by rotating the take-up spool. Therefore, the filmstrip of the leader-advancing type cassette need not have a lot of successive perforations which like conventional 135-type filmstrips have for engagement with the sprocket wheel or the take-up spool.
  • the filmstrip of the leader advancing type cassette has at least a perforation per picture frame.
  • the perforation is intended to be detected by a photo-sensor in the camera to determine each frame exposure location and position it in an exposure aperture of the camera. Since these perforations for frame positioning are disposed in association with the frame exposure locations, the filmstrip of the leader advancing type cassette, hereinafter referred to as a new type filmstrip, has no positioning perforation in its leader and trailer where no picture frame is to be recorded.
  • a section which extends over the frame exposure locations of each individual filmstrip will be referred to as a recording section.
  • apparatuses for manufacturing the new type filmstrip have been suggested, one of which uses a die set having a number of punches and dies corresponding to the number of frame exposure locations to be provided in the individual filmstrips formed from the long film.
  • the apparatus makes the corresponding number of perforations at a time in the recording section of each individual filmstrip.
  • the number of frame exposure locations per filmstrip will be referred to as film frame number.
  • a similar method has conventionally been applied to manufacturing 110-type filmstrips.

  • the suction chamber 15 transiently stores an appropriate length of the long film 12 before being fed to the die set 17 through a pass roller 16.
  • the die set 17 has a punch holder 19 with the same number of punches 18 as the film frame number, and a dies plate 21 with the corresponding number of dies 20.
  • the punches and dies 18 and 20 are arranged at the same intervals as the frame exposure locations.
  • An air cylinder 22 is driven to move the punch holder 19 down to the dies plate 21 while the long film 12 stops on the dies plate 21, making the same number of perforations as the film frame number at a time.
  • first vacuum suction drum 24 Downstream of the die set 17 are disposed a first vacuum suction drum 24, a second vacuum suction chamber 25, a second vacuum suction drum 26, a side-printer 27 and a cutter 28 in serial fashion.
  • the first and second suction drums 24 and 26 have suction holes formed through respective peripheral surfaces, and are driven by servo motors 30 and 32, respectively.
  • the suction drums 24 and 26 transport the film 12 while sucking it on the peripheral surfaces.
  • an encoder 31 connected to the servo motor 30 monitors the rotational amount of the drum 24 to detect the transported length of the film 12.
  • the drum 24 starts rotating after each die-punching the perforations P in the film 12, and stops rotating when the film 12 is transported by a unit length which is predetermined in accordance with the film frame number.
  • the next recording section to be perforated is positioned in the die set 17.
  • the perforated section of the film 12 is transported through the first suction drum 24 to the second suction chamber 25 to transiently store an appropriate length of the film 12 before being fed to the cutter 28.
  • the film 12 is transported from the suction chamber 25 to the cutter 28 through the second suction drum 26, while an encoder 33 connected to the servo motor 32 monitors the rotational amount of the second suction drum 26 to detect the transported length of the film 12.
  • the detection signal from the encoder 33 is sent to the side-printer 27.
  • the side-printer 27 optically records data such as the name of film manufacturer, frame serial numbers and the like as latent images of characters and bar codes along one or both of lateral sides of the film 12 while the film 12 is being transported through the second suction drum 26.
  • the side-printer 27 is movable toward a peripheral position of the second suction drum 26 where the transported film 12 tightly fit on, so that the side-printer 27 faces the photosensitive emulsion surface of the film 12 at a constant distance.
  • the peripheral position may be referred to as a side-print position.
  • the second suction drum 26 stops rotating when it has transported the film 12 by the predetermined unit length. Then, the cutter 28 is actuated to cut the film 12 into individual filmstrips.
  • the new type filmstrip may have variations in the film frame number like the conventional filmstrips.
  • the apparatus as shown in Fig. 13 is provided with interchangeable punch holders having different numbers of punches from one another.
  • One of the punch holders is selected in correspondence with the film frame number of the filmstrips designated to be produced.
  • the unit length for the transport of the film 12 through the suction drums 24 and 26 is changed in accordance with the selected film frame number.
  • the second suction chamber 25 absorbs the variation by changing the storing length of the film 12.
  • the side-print position is unchanged independently of the film frame number.
  • the number of times of recording as well as a side-print end position vary depending on the film frame number, as a side-print end position.

Moreover, since the drums 24 and 26 must have a diameter large enough to ensure the suction of the film 12, the distance between the cutter 28 and side-printer 27, and thus the length of the film 12 from a cut position B to the side-print position C must correspondingly be long, as is shown in Fig. 14, wherein the cut position B is a position to cut trailing ends 6 of individual filmstrips 5, that is, an innermost end in a cassette shell.
  • a film trailer length L3 into a range from 50 mm to 100mm or so, wherein the film trailer length L3 represents the length from the trailing end 6 of the individual filmstrip 5 to the start of its recording section.

  • CH-A-554 225 discloses a device for cutting and perforating segments with predetermined unit lengths from a long foil, whereby cutting and punching is actuated simultaneously.
  • the perforations extend perpendicularly to the transport direction of the foil such that each segment irrespective of its length has the same number of peforated holes. Variable lengths can be achieved by varying the distance between cutting device and punching device.
  • JP-A-6 170 795 on which the preamble of claim 1 is based discloses a perforation device for perforating filmstrips that comprises a die set unit with die sets and respective punches which are aligned along the feed direction of the film.
  • the device is designed for eliminating the need for exchanging the die set when filmstrips having different numbers of perforations are to be made.
  • a control part is operated to actuate the corresponding punches and to actuate a transporting device to transport said film by a unit length after actuation of the punches, said unit length being dependent on the number of perforations.

Since the leading end and the trailing end of two adjacent filmstrips having fifteen perforations P1 to P15 formed therethrough are cut by the cutter 28 in synchronism with the die-punching of the first and second die sets 46 and 47, the preceding one of the two filmstrips is cut off the film 12 into an individual 15-exposure filmstrip. But the leading end of the following filmstrip is transported farther than the cutter 28 as a result of the rotation of the suction drum 60 by the unit length L4b for 25-exposure filmstrip.
  • the film buffer length is L4 + L3 for any film frame number N, by selecting a factor "1" to multiply the unit length L4 in the above-described definition. In this way, merely a defective filmstrip will be produced at each film frame number change.
  • die-punching of the first and second die sets 46 and 47 and cutting of the cutter 28 are repeated in synchronism with each other, and the side-printer 27 prints data of 25-exposure filmstrip along the side-print zone 42 while the film 12 is transported by the unit length L4b after each die-punching, in the same way as above, to produce 25-exposure filmstrips.
  • the movable roller 56 is moved to the position Z to adjust the film buffer length to the unit length L4c for 35-exposure filmstrip. Then, the first to third die sets 46 to 48 are simultaneously actuated to make thirty-five perforations P1 to P35 at a time. Thereafter, the suction drum 60 is driven to transport the film 12 by the unit length L4c, while the side-printer 27 prints data of 35-exposure filmstrip along the side-print zone 42. The same operation is repeated to produce 35-exposure filmstrips in continuous succession.
  • the present invention is applicable to a case where a pair of perforations P1a and P1b; P2a and P2b; ... P N a and P N b are provided for each frame exposure location, as is shown in Fig. 11.
  • Two perforations for assigning longitudinal ends of each frame exposure location facilitate more accurate positioning of the frame exposure location in the exposure aperture of the camera. It is also possible to dispose a pair of perforations on opposite lateral sides of each frame exposure location.
  • the air cylinders 46c, 47c and 48c are selectively driven by the controller 80 for each die-punching stroke of the associated die sets 46 to 48, it is also possible to provide a cam 90 and a lever 91, as is shown in Fig. 12, for actuation of each punch holder 93.
  • the lowermost position of the punch holder 93 in the die-punching stroke is changed over by an air cylinder 92 connected to the punch holder 93, between an active position and an inactive position.
  • the cam 90 is connected to the air cylinder 92 through the lever 91.
  • the lever 91 has a cam follower 95 at its one end, the cam follower 95 being always contacted against the cam surface of the cam 90, and is connected to the air cylinder 92 at the opposite end, with its fulcrum 94 disposed in an intermediate position.
  • one rotation of the cam 90 causes one stroke of the punch holder 93.
  • the punch holder 93 cannot perforate the film 12 placed on a dies plate 96.
  • Fig. 12 shows only one punch holder 93, a plurality of such punch holders 93 are disposed along the film 12, and only those punch holders 93 which are set in the active position by the associated air cylinders 92 can effect die-punching by one stroke. This embodiment is suitable for faster die-punching operation.
  • cam 90 and the lever 91 are provided for each die set, and are actuated in synchronism with one another in the above-embodiment, it is possible to actuate a plurality of punch holders with air cylinders by a single cam and a lever.
  • the present invention is not only applicable to manufacturing photographic filmstrips, but also to manufacturing other kinds of strips or webs from a long strip of resin film or paper.
