Abstract

880,570. Magnetic picture records. TOKYO DENKI KAGAKU KOGYO KABUSHIKI KAISHA, and HOSHINO, Y. Sept. 1, 1958 [Sept. 2, 1957; Sept. 12, 1957 (2); Nov. 4, 1957 (2)], No. 27979/58. Class 40 (2). To produce a plurality of copies of a magnetic sheet picture record, paper 1 is fed from a stock roll 2 past printing and drying means 4, 5, 6, which produce visual information on one side of the paper, past coating and drying means 7, 8, 9, which impart a broad stripe of magnetic ink to the other side of the paper, through an intermittent feed arrangement I to a magnetic printer D after which the strip is cut into separate sheets at C. A master record 24 is mounted to a plate 17, by means of which it is brought into close contact with the strip 1 and the magnetic properties of the two are such that an oscillatory magnetic field produced by the discharge of a capacitor in a winding 26 reproduces the magnetic pattern of the master sheet on the strip 1 without significant deterioration of the master sheet. While the copy is still clamped, registration holes are produced by punches 13 to enable the record to be located over co-operating pins in a reproducing machine. In a further embodiment (Fig. 7, not shown), reinforcements are punched out and secured to the records where the locating holes are punched subsequently. Specifications 794,788, 796,251 and 850,291 are referred to.
