Definitions

  • FIG-2 FIGS INVENTORS AK
  • Field of the Invention This invention relates to a method of cutting a photographic paper web, and more particularly to a method of automatically cutting the photographic paper web by the use of electromagnetic means.
  • one method utilizes an optical means for optically detecting a black ink mark provided on the photographic paper.
  • Another method utilizes electrical means for detecting the variation in resistance of a paper provided with a graphite mark.
  • a further method utilizes mechanical means for mechanically detecting a mechanical mark provided on the paper to define the position to be cut or position spaced from the position to be cut by a prescribed length.
  • Another object of the present invention is to provide a method of cutting a paper in which detection of the position to be cut is achieved by electromagnetic means.
  • Still another object of the present invention is to provide a method of cutting a paper by detection of the position thereof to be cut by the use of a pair of magnetic heads one of which records a mark on the paper when the paper is printed and the other of which detects the recorded mark to operate the paper feeding means and paper cutting means.
  • FIG. 1 is a rear perspective view of a photographic paper web showing the magnetically provided marks thereon.
  • FIG. 2 is a partial schematic elevational view of a paper cutting apparatus for carrying out the method of cutting according to the present invention in relation with the electromagnetic system shown in block diagram.
  • FIG. 3 is a side view of a marking magnetic head and a detecting head arranged in accordance with an embodiment of the present invention.
  • FIG. 4 is a side view of a marking magnetic head and a detecting head arranged in accordance with another embodiment of the present invention.
  • FIG. 5 is a side view of a marking magnetic head and a detecting head arranged in accordance with still another embodiment of the present invention.
  • FIG. 6 is a side view of a marking magnetic head and a detecting head in accordance with a further embodiment of the present invention.
  • a photographic paper web 1 is provided marks 2 thereon at positions corresponding to the printed frames thereof defined by boundaries 3.
  • a roll 4 of the photographic paper is unrolled and fed along a predetermined passage.
  • a magnetizing device 5 for magnetically marking the photographic paper 1
  • a detecting device 6 for detecting the marks 2 magnetically recorded
  • a pair of feeding rollers 7, and a cutting device 8 arranged in downstream order.
  • the detecting device 6 is a magnetic head in the embodiment shown in FIG. 2 connected to an amplifier 10 for amplifying the detecting signal from the magnetic head 6.
  • the amplified signal from the amplifier 10 is transmitted to an electromagnetic clutch 12.
  • the reference numeral 11 indicates a driving motor for rotating a cam 13 operating cutter 8 through the electromagnetic clutch l2 and for rotating the paper feeding rollers 7.
  • the marks 2 provided on the paper 1 are made by applying magnetizable material thereon and magnetized by the magnetizing device 5 which is a magnetic recording head in the embodiment shown in FIG. 2. That is, the paper 1 is provided with a magnetizable material coating at the positions shown in FIG. 1 when the photographic paper is printed, and then after developing the paper 1 is unroller from the roll 4 and fed along the path in which the magnetizing device 5 and the detecting device 6 are arranged. When fed along this passage, the magnetizable material at the position 2, representing the mark, is magnetized by the magnetizing device 5 and then the magnetized mark 2 is detected by the detecting magnetic head 6.
  • the detected signal is amplified by the amplifier l0 and the amplified signal is transmitted to the electromagnetic clutch 12.
  • the rotation of the motor 11 is transmitted to the paper feeding rollers 7 through the clutch 12.
  • the amplified signal is transmitted from the amplifier 10 to the electromagnetic clutch 12
  • the paper feeding rollers 7 are stopped and rotation of the cam 13 is initiated.
  • the cam 13 during rotation makes the cutter 8 cut the paper 1 after the predetermined time designed by the cam shape thereof, so that the paper 1 may be cut at the position detected by the detecting device 6.
  • the arrangement or combination of the magnetizing device 5 and the detecting device 6 may be any of the various combinations such as shown in FIGS. 3 through 6.
  • FIG. 3 an embodiment involving an arrangement of two magnetic heads is shown in which the magnetizing head is a permanent magnetic head and the detecting head is an electromagnetic coil head.
  • FIG. 4 shows another embodiment of the arrangement of the two magnetic heads in which the magnetizing head is an electromagnet and the detecting head is also an electromagnetic coil head.
  • FIG, 5 is shown still another embodiment of the arrangement of the heads in which the magnetizing head is a permanent magnetic head and the detecting magnetic head is a magnet diode.
  • FIG. 6 A further embodiment of the arrangement of the heads is shown in FIG. 6 in which the magnetizing head is an electromagnetic head and the detecting head is a magnet diode.
  • the magnetizable mark 2 on the paper is magnetized and detected so that the paper may be cut at the position of the boundary 3 of the frames by the combination of the clutch 12, feeding roller 7 and cam 13 working in response to the detected signal fro the amplifier l0.
  • a method of cutting a running photographic paper web after photographic development comprising:
