Abstract: 704,986. Statistical apparatus. BRITISH TABULATING MACHINE CO., Ltd. Feb. 26, 1952 [May 11, 1951], No. 11172/51. Class 106 (1) Apparatus for sensing record cards of the type printed with separate data representing areas of magnetic ink comprises magnetic sensing means, and means for uniformly magnetizing the magnetizable areas with a sufficiently high intensity to cause operation of the sensing means when the areas are applied thereto, the sensing means and magnetizing means being arranged so that the magnetizable areas can be magnetized by the magnetizing means immediately prior to sensing. Cards 1 are fed from a magazine 3 by a picker 4 in known fashion to feed rolls 6, Fig. 1, and under a permanent magnet 10 which magnetizes any data representing areas which have been marked on the card with magnetic ink. The cards are then passed under a reading head 11 which senses the magnetized marks in a preselected column. The impulse from the sensing head 11 is passed to a two stage amplifier V1, V2 feeding a cathode coupled flip-flop circuit V3, V4, Fig. 5, the output of which is fed to a cathode follower V5 having the relay R1 as its cathode load. Energization of the relay R1 causes the magnet 13 to be operated to direct the card into one of the sorting paths 15 in timed relationship to the value of the mark in well known manner. The card 1, Fig. 2, bears printed matter, for example, a cheque, on its face and the magnetic data representing marks 2 on the back or, alternatively, if the card is made of more than one ply. The marks may be printed on one of the inside faces of one of the plies. In Fig. 2 the value of the marks shown reading from right to left is 539.
